Öğe Accuracy of the London Atlas, Haavikko's Method and Cameriere's European Formula of dental age estimation in Turkish children(Elsevier B.V., 2022) Sezer, Berkant; Çarıkcıoğlu, BurakAge estimation is a mandatory procedure when the chronological age is unknown or uncertain. Dental development is the preferred characteristic for estimating a child's age. There are many methods for dental age estimation, but their reliability can differ between populations. This study compared the accuracy of three of these methods—the London Atlas (LA), Haavikko's method (HM), and Cameriere's European formula (CF)—in Turkish children living in northwestern Turkey. Panoramic radiographs of 980 children from northwestern Turkey aged between 6.00 and 14.99 years were examined for the whole study group and separately for different ages and sexes by all three methods. Statistical differences between chronological age and dental age were tested using the paired sample t-test and the Wilcoxon signed-rank test. The LA, HM, and CF accuracies were determined based on the mean absolute error. Spearman's rank correlation coefficient showed that the correlation between chronological age and dental age for both sexes was linear for all methods. The LA overestimated the chronological age by 0.09 years, while HM and CF underestimated it by 0.49 and 0.11 years, respectively. The difference between dental age and chronological age was significant in all samples, for all methods, except for the LA in boys. When boys, girls, and the total sample were evaluated, values with the lowest mean absolute error were obtained by HM and were statistically significant in all three groups. Therefore, HM is more accurate than the LA and CF for dental age estimation in Turkish children living in northwestern Turkey.Öğe ASSESSMENT OF DENTAL FEAR IN CHILDREN WITH MOLAR-INCISOR HYPOMINERALIZATION(Termedia Publishing House Ltd., 2022) Sezer, Berkant; Tuğcu, Nihan; Çalışkan, Cansu; Durmuş, Başak; Kargül, BetülIntroduction: Dental fear is a common unpleasant emotional response that occurs in situations related to dental treatment. Since children affected by molar-incisor hypomineralization (MIH) receive much more dental treatment than their healthy peers, these children may have more dental fear and behavioral problems. Objectives: The aim of the study was to assess the relation between the presence and severity of MIH and dental fear. Material and methods: Study group involved a sample of 127 children, aged between 8 and 12 years with MIH, showing a high-risk of caries, and 99 children were included into control group. In the wake of intra-oral examination according to the American Academy of Pediatric Dentistry guideline and DMFT/dmft indices, Children’s Fear Survey Schedule – Dental Subscale (CFSS-DS) was applied to each child. Mean value of independent groups for normally distributed data was compared using independent samples t-test. Spearman’s correlation was applied for correlations between DMFT/dmft scores and CFSS-DS scores. P-value of < 0.05 was considered statistically significant. Results: The final number of individuals affected by MIH in this study was 127 with approximately equal numbers for each age group. The mean CFSS-DS scores were 31.41 ± 10.73 for the MIH-group, and 31.60 ± 6.21 for the controls, respectively. The mean values did not differ significantly between children with and without MIH (p = 0.870). There were also no statistically significant differences in severe MIH (31.38 ± 10.93) compared with the control group (31.60 ± 6.21) (p = 0.890). Conclusions: The study’s findings revealed that there is no relation between the existence and severity of MIH and dental fear. © 2022 Polish Dental AssociationÖğe Assessment of the oral health status of children with chronic kidney disease(Springer Science and Business Media Deutschland GmbH, 2023) Sezer, Berkant; Kaya, Remziye; Kodaman Dokumacıgil, Nur; Sıddıkoğlu, Duygu; Güven, Serçin; Yıldız, Nurdan; Alpay, Harika; Kargül, BetülBackground There are various oral symptoms related to the disease and its management in individuals with chronic kidney disease (CKD). The aim of the study was to investigate the oral health status of children with different stages of CKD, kidney transplant recipients (KTR), and healthy children. Methods A total of seventy-one children diagnosed with CKD and fifty-two healthy children were included in the study. Each patient was examined for dental caries by the decayed-missing-filled-teeth (DMFT/dmft) index and the International Caries Detection and Assessment System (ICDAS-II), developmental defects of enamel (DDE) by the DDE index, and oral hygiene by the debris (DI), calculus (CI), and simplified oral hygiene (OHI-S) indices. Results The median number of DMFT/dmft was 1.00 (interquartile range (IQR):1.00-4.00) in children with stage 1-3 CKD, 0.00 (IQR: 0.00-2.50) in stage 4-5 children, 0.00 (IQR: 1.00-3.00) in KTR, and 8.00 (IQR: 1.00-13.00) in healthy children. According to ICDAS-II categories, the percentage of children with severe caries was 53.8% in healthy children, while it was 44.4% in KTR, 25.9% in stage 1-3, and 11.4% in stage 4-5 children. While the percentage of children with DDE was 88.8% in KTR, 80% in stage 4-5, and 66.7% in stage 1-3 children, this rate was 44.2% in healthy children. The highest mean OHI-S score was observed in stage 4-5 children (2.10 +/- 1.08), followed by KTR (1.46 +/- 1.19), stage 1-3 (1.27 +/- 0.61), and healthy children (0.45 +/- 0.44), respectively. Conclusions Compared to healthy children, children with CKD had more debris accumulation, calculus formation, and more DDE but a lower severity of dental caries.Öğe Association between serum biomarkers and oral health status in children with chronic kidney disease: A cross-sectional study(Springer Science and Business Media Deutschland GmbH, 2023) Sezer, Berkant; Kodaman Dokumacıgil, Nur; Kaya, Remziye; Güven, Serçin; Türkkan, Özde Nisa; Çiçek, Neslihan; Alpay, Harika; Kargül, BetülObjectives: The aim of this study was to investigate the association between serum biomarkers and oral health parameters in children with chronic kidney disease (CKD). Materials and methods: Serum hemoglobin, blood urea nitrogen, serum creatinine, calcium, parathormone, magnesium, and phosphorus levels were measured in 62 children with CKD aged between 4 and 17 years. Intraoral examinations of the patients were performed by two different pediatric dentists. Dental caries was assessed using the decayed-missing-filled-teeth (DMFT/dmft) indexes, and oral hygiene was assessed using the debris (DI), calculus (CI), and simplified oral hygiene (OHI-S) indexes. Spearman’s rho coefficient and generalized linear modeling were used to examine the association between serum biomarkers and oral health parameters. Results: The results of the study showed that there were negative and statistically significant correlations between serum hemoglobin and creatinine levels and dmft scores in pediatric patients with CKD (p = 0.021 and p = 0.019, respectively). Furthermore, blood urea nitrogen levels and DI and OHI-S scores (p = 0.047 and p = 0.050, respectively); serum creatinine levels and DI, CI, and OHI-S scores (p = 0.005, p = 0.047, p = 0.043, respectively); and parathormone levels and CI and OHI-S scores (p = 0.001 and p = 0.017, respectively) were found to be positively and statistically significantly related. Conclusions: There are associations between various serum biomarker levels and dental caries and oral hygiene parameters in pediatric patients with CKD. Clinical relevance: The impact of changes in serum biomarkers on oral and dental health is important for dentists’ and medical professionals' approaches to patients' oral and systemic health.Öğe Association between work-related musculoskeletal symptoms and quality of life among dental students: a cross-sectional study(BMC, 2022) Sezer, Berkant; Kartal, Sinan; Siddikoglu, Duygu; Kargul, BetulBackground Dental students are frequently affected by work-related musculoskeletal symptoms (WMSs) due to reasons such as working conditions, difficult education process and long work periods. The aim of the study was to investigate the frequency and anatomical distribution of WMSs, and its effect on the quality of life (QoL) in dental students. Methods Sociodemographic and health-related characteristics of one-hundred and five dental students were recorded. WMSs were scored by the participants with the Nordic Musculoskeletal Questionnaire. Then, participants were asked to evaluate their QoL by scoring the World Health Organization Quality of Life-Brief Form. Differences between independent groups for continuous variables were evaluated by Student's t-test and ANOVA as appropriate. Linear regression analysis was performed to determine the effect of demographic and health-related parameters in predicting the QoL subscales. Results The most common painful region in the last 12 months was the neck (66.7%). The body region with the most WMSs in the last 7 days was the upper back (43.8%). Physical health-related QoL of those with diagnosed musculoskeletal symptoms, and general health-related QoL of those using medicine due to any musculoskeletal symptoms were found to be statistically significantly lower (p = 0.018, p = 0.041, respectively). It was observed that the general and physical health, psychological well-being, and social relationship of the participants who reported the presence of neck pain in the last 7 days were statistically significantly lower (p = 0.003, p < 0.001, p = 0.004, p = 0.012; respectively). According to multiple regression analyses, pain occurrence in the body in the last 12 months and/or in the last 7 days had a negative impact on the participants' general and physical health, psychological well-being, social relationship, and environmental status and related QoL (p = 0.026, p = 0.047, p = 0.021, p = 0.001, p = 0.027, respectively). Conclusions The results of this study show that dental students' body regions, especially the neck and the back, are affected by WMSs. These negative changes observed in the body had a negative effect on the QoL of the dental students.Öğe CAN ARTIFICIAL INTELLIGENCE EFFECTIVELY RESPOND TO FREQUENTLY ASKED QUESTIONS ABOUT FLUORIDE USAGE AND EFFECTS? A QUALITATIVE STUDY ON CHATGPT(Int Soc Fluoride Research, 2023) Buldur, Mehmet; Sezer, BerkantObjectives: The frequently asked questions about fluoride, as determined by the American Dental Association (ADA), were asked to Generative Pre-trained Transformer (ChatGPT) and the answers were qualitatively compared with those of the ADA. Methods: Questions were posed to ChatGPT on May 8th and 16th, 2023, and the responses were recorded. The answers from the ADA webpage were also recorded. The responses were compared for similarity in word and meaning, both within ChatGPT's responses over a one-week interval and between ChatGPT's responses and ADA's responses. Results: While the responses provided by ChatGPT with a one-week interval had similar information content, in the comparison made with the ADA, ChatGPT provided more detailed and scientific answers. However, both shared the same central idea about fluoride and its role in oral health. Conclusions: The accuracy and reliability of the answers given by the applications developed with artificial intelligence (AI) are of great importance, and it has been seen that the answers given by ChatGPT to the questions asked about fluoride are sufficient and reliable. Clinical Relevance: Advancements in technology, particularly in artificial intelligence, enable individuals to access accurate and reliable information about a topic quickly and in appropriate ways.Öğe Comparative evaluation of the remaining dentin volume following instrumentation with rotary, reciprocating, and hand files during root canal treatment in primary molars: An ex vivo study(Elsevier Taiwan, 2024) Eren, Irem; Sezer, BerkantBackground/purpose: The effectiveness of root canal treatments with different file systems in primary teeth is important in terms of clinical practice and the use of file systems that work with different principles in primary tooth pulpectomy is becoming widespread. The amount of remaining dentin in the coronal region of the root is important in terms of the prognosis of the tooth and the long-term success of the treatment in teeth that have undergone root canal treatment. The aim of this study was to evaluate the remaining dentin volume in the coronal part of the root after the use of rotary, reciprocating, and conventional hand files in primary tooth pulpectomy. Materials and methods: A total of 30 primary molars were divided into three groups. In each group, the preparations were made with three different file types: WaveOne Gold, which works with reciprocating motion; TruNatomy, which works with rotational motion; and conventional hand files. The three-dimensional images were evaluated for remaining dentin volume in the 2-mm coronal part of the root. Group means were compared using one-way analysis of variance, and post hoc analyses were performed with the Tukey test. Results: There was no statistically significant difference between the groups in terms of preoperative and postoperative dentin volume (P > 0.05). The mean difference after preparation was observed the most in the WaveOne Gold group and the least in the TruNatomy group. When the mean percentage differences were evaluated, it was observed that statistically significantly more dentin volume was preserved after the preparation with TruNatomy than with WaveOne Gold (P = 0.021). Conclusion: In primary tooth pulpectomy, file systems working with rotational motion can be preferred over file systems working with reciprocating motion in preserving the amount of dentin in the 2-mm coronal part of the root.Öğe Comparison of the Effects of WaveOne Gold, TruNatomy, and Conventional Hand Files on Remaining Dentin Volume in the Coronal Part of the Root and Preparation Efficiency in Mandibular Molars(Elsevier Inc., 2023) Eren, İrem; Sezer, BerkantIntroduction: The use of file systems that work with different principles in root canal treatment is becoming widespread. The aim of this study was to evaluate the remaining dentine volume in the coronal region of the root and preparation efficiency after the use of conventional hand files, WaveOne Gold; which works with reciprocating motion, and TruNatomy; which works with rotational motion in the root canal treatment of mandibular molar teeth. Methods: All canals of permanent mandibular molars (n = 36) were used. Root canals in each group (n = 12) were prepared with conventional hand files, WaveOne Gold, and TruNatomy. The three-dimensional images were evaluated for remaining dentine volume in the coronal two-millimeter region of the root and change in volume of the entire root canal space. Results: There was no statistically significant difference between the groups in terms of mean differences pre and postpreparation (P > .05). The mean differences after preparation were observed the most in the WaveOne Gold group and the least in the TruNatomy group in the coronal two-millimeter region of the root and entire canal volume, but the differences were not significant (P > .05, P > .05, respectively). Conclusions: Conventional hand files, WaveOne Gold working with reciprocating motion, and TruNatomy working with rotational motion, which are the file systems used in the study, are not superior to each other in terms of remaining dentin volume in the coronal two-millimeter region of the root and preparation efficiency in the entire root canal space in mandibular molars.Öğe Dental age and tooth development in children with molar-incisor hypomineralization: A case-control study(Elsevier Ltd, 2022) Sezer, Berkant; Çarıkçıoğlu, Burak; Kargül, BetülObjective: The aim of the study was to determine the dental age for the evaluation of tooth development in children with molar-incisor hypomineralization (MIH) by using the Willems method, Cameriere-European formula, and London Atlas. Design: Panoramic radiographs of 308 children between the ages of 6–13 diagnosed with MIH and the same number of sex- and age-matched children without MIH were evaluated by two different examiners using the Willems method, Cameriere-European formula, and London Atlas. The mean difference between chronological age and dental age in both groups was calculated for each sex and age. The mean absolute error was used to determine the accuracies of the Willems method, Cameriere-European formula, and London Atlas. Results: There was a statistically significant difference found only in Willems method in dental age estimation between the groups with and without MIH (P = 0.001). In the evaluation performed with Cameriere-European formula and London Atlas, which are more accurate methods for dental age estimation in both groups, no statistically significant difference was found in dental age estimation between the two groups (P = 0.322, P = 0.290, respectively). There was a statistically significant intense linear correlation for three methods in both groups (P < 0.001). Conclusions: MIH, which is a developmental enamel defect, does not affect dental age and tooth development since there was no significant difference between groups with and without MIH according to the evaluations made with accurate dental age estimation methods.Öğe Dental age estimation with fewer than mandibular seven teeth: An accuracy study of Bedek models in Turkish children(Springer Heidelberg, 2022) Carikcioglu, Burak; Sezer, BerkantObjectives One or more missing teeth, such as hypodontia, make it difficult to obtain accurate results in age estimation methods. This paper aims to test the accuracy of the models developed by Bedek et al. that can estimate age with fewer than seven teeth for Turkish children. Materials and methods Panoramic radiographs of 1118 children (540 girls and 578 boys) aged between 6 and 16 years were evaluated using the Willems method and Bedek models for the entire sample and for different ages and sexes. Differences between dental age (DA) and chronological age (CA) calculated for all methods for each sex and all age groups were analyzed the paired sample t-test and Wilcoxon signed rank test. The accuracy of the DA estimation methods was determined by the proximity of DA to CA by calculating mean absolute error (MAE). Results While all Bedek models underestimated CA by 0.2 to 0.1 years, the Willems method overestimated CA by 0.3 years. DA-CA difference in the total sample and girls was statistically significant in all methods. In the total sample, the seven- and four-teeth models had the lowest MAE, while the one-tooth model had the highest MAE. Conclusions Seven- and four-teeth models were the most suitable for age estimation, and all models except the one-tooth model were found to be more accurate than the Willems method in northwestern Turkish children.Öğe Does the scientific literature provide sufficient information on incisors affected by molar incisor hypomineralisation?(Springer Science and Business Media Deutschland GmbH, 2023) Sezer, BerkantMolar incisor hypomineralisation (MIH), which was defined for the first time by Weerheijm et al. (2001) twenty-one years ago as a qualitative, hypomineralised enamel defect in which at least one permanent first molar is affected and the condition is frequently observed in permanent incisors, remains an important health problem.Öğe Effect of casein phosphopeptide amorphous calcium fluoride phosphate and calcium glycerophosphate on incisors with molar-incisor hypomineralization: A cross-over, randomized clinical trial(Ios Press, 2022) Sezer, Berkant; Tugcu, Nihan; Caliskan, Cansu; Durmus, Basak; Kupets, Tatiana; Bekiroglu, Nural; Kargul, BetulBACKGROUND: Within the scope of minimally invasive dentistry, the use of different biocompatible remineralization agents on incisors affected by molar-incisor hypomineralization (MIH) gains importance. OBJECTIVE: To evaluate the effect of casein phosphopeptide amorphous calcium fluoride phosphate (CPP-ACFP) and calcium glycerophosphate (CaGP) in mineral density (MD) of white/creamy and yellow/brown demarcated opacities on incisors affected by MIH by means laser fluorescence (LF). METHODS: As a cross-over, randomized trial, twenty-two children with 167 incisors affected by MIH were recruited and randomly assigned to one of the two different agents and crossed over to other agents with two weeks washout in between. Incisors were examined by using LF at all before and after three months periods. RESULTS: The results of the paired t-tests for determining the period effect between the baseline findings showed significant difference in white/creamy and yellow/brown demarcated opacities of LF values for both groups (p < 0.05). The difference between both groups according to after categorization of 20% increasing in MD in the percent of change before and after application on LF values; was not found statistically significant in white/creamy (p = 0.970) and yellow/ brown (p = 0.948) opacities. CONCLUSIONS: The primary outcome was CPP-ACFP and CaGP had a positive effect in decreasing hypomineralization on MIH-affected enamel for three months period.Öğe Effect of dental caries on dental age and development in adolescents between 12-15 years(AVES, 2022) Sezer, Berkant; Çarikçioğlu, BurakObjective: The aim of this study was to investigate the effect of dental caries on dental age and development in adolescents between the ages of 12-15. Methods: The evaluation of dental caries in 368 patients between the ages of 12-15 was made using the DMFT index, and the estimation of the dental age was made using the Cameriere-European formula on the panoram-ic radiographs. For each age and gender group, the mean DMFT scores was calculated separately and the mean DMFT values were taken as the cutoff point. Paired-samples t-test, Wilcoxon test and chi-square test were used in the statistical analysis of the data. Results: It was observed that dental caries did not have a statistically significant effect on dental age and development in the total study sample (P >.05). In the evaluation performed at different age and DMFT score level, dental development was found statistically significantly delayed in boys with dental caries level above the DMFT mean at the age of 12 years (P =.016), while dental development was found to be statistically significantly advanced in boys with dental caries level below the DMFT mean of 13 years old (P =.027). Conclusion: It has been observed that dental caries has effects on dental age and development in different age and gender groups. There is a need for studies in larger populations and with different evaluation methods and indices. © 2022, AVES.

Study Design: Fifty-three children (n=401 lesions) with MIH were randomly divided into three groups: (1)calcium glycerophosphate (CaGP), (2)casein phosphopeptide amorphous calcium fluoride phosphate (CPP-ACFP) and, (3)control (1450 ppm fluoride toothpaste). Remineralization was evaluated by means of LF, at baseline, after one and threemonths. Anova Test for Repeated Measurements in intra-group comparisons in evaluating the effectiveness of remineralization agents. One-way Variance Analysis (ANOVA) and Tukey-Kramer Multiple Comparison test were used in the comparisons between groups and, Student Newman Keuls Multpile Comparison Test was used to determine the differences between the measurement averages in case of p<0.05. Results: There was a significant improvement in MIH-lesions over time in all groups (p 0.001), with no differences between groups. The highest percentage of change was observed in CPP-ACFP in lesions LF???20 scores and the mean percentage of change LF 20 scores, the highest percentage changes in CaGP. There was no significant difference between the groups over the time for all the used outcome measures (p>0.05). Conclusion: The additional use of both mineral containing agents in MIH-affected teeth improved these hypomineralized lesions with mineral deposition. Even if both agents could be used in the hypomineralized teeth with demarcated opacities, future studies are recommended the long-term effect of these mineral containing agents with longer observation and a larger sample size.Öğe Evaluating the accuracy of Chat Generative Pre-trained Transformer version 4 (ChatGPT-4) responses to United States Food and Drug Administration (FDA) frequently asked questions about dental amalgam(BMC, 2024) Buldur, Mehmet; Sezer, BerkantBackground The use of artificial intelligence in the field of health sciences is becoming widespread. It is known that patients benefit from artificial intelligence applications on various health issues, especially after the pandemic period. One of the most important issues in this regard is the accuracy of the information provided by artificial intelligence applications.Objective The purpose of this study was to the frequently asked questions about dental amalgam, as determined by the United States Food and Drug Administration (FDA), which is one of these information resources, to Chat Generative Pre-trained Transformer version 4 (ChatGPT-4) and to compare the content of the answers given by the application with the answers of the FDA.Methods The questions were directed to ChatGPT-4 on May 8th and May 16th, 2023, and the responses were recorded and compared at the word and meaning levels using ChatGPT. The answers from the FDA webpage were also recorded. The responses were compared for content similarity in Main Idea, Quality Analysis, Common Ideas, and Inconsistent Ideas between ChatGPT-4's responses and FDA's responses.Results ChatGPT-4 provided similar responses at one-week intervals. In comparison with FDA guidance, it provided answers with similar information content to frequently asked questions. However, although there were some similarities in the general aspects of the recommendation regarding amalgam removal in the question, the two texts are not the same, and they offered different perspectives on the replacement of fillings.Conclusions The findings of this study indicate that ChatGPT-4, an artificial intelligence based application, encompasses current and accurate information regarding dental amalgam and its removal, providing it to individuals seeking access to such information. Nevertheless, we believe that numerous studies are required to assess the validity and reliability of ChatGPT-4 across diverse subjects.Öğe Evaluation of the differences in the localization of the lingula mandibulae according to pubertal development in children: A new anthropological and forensic approach(Elsevier Ltd, 2024) Eren, Hakan; Sezer, Berkant; Deniz, YeşimObjective: This study aims to investigate changes in lingula mandibulae localization before and after puberty and sex differences. Design: 288 panoramic radiographs evaluated retrospectively were divided into four groups according to pubertal development: under and over 10 years old for females and under and over 11 years old for males. Four anatomic sites were used as reference points: (a) the anterior border of the ramus; (b) the posterior border of the ramus; (c) the deepest point of mandibular notch; and (d) the angulus mandibulae. The ratio of the distances from the lingula mandibulae to points (a) and (b) and the ratio of the distances from the lingula mandibulae to points (c) and (d) were determined. Two-way ANOVA was performed to assess differences between subgroups based on sex and puberty, and a Bonferroni post-hoc test was performed for multiple comparisons. Results: Puberty and sex has a significant interaction effect on the vertical location of the lingula mandibulae. Postpubertal lingula mandibulae is positioned proportionally more anteriorly by prepubertal localization. In addition, the lingula mandibulae is situated more posteriorly in females compared to males. A significant interaction effect of puberty and sex was observed in relation to the vertical positioning of the lingula mandibulae. Conclusions: The spatial localization of the lingula mandibulae and its spatial displacement with age can be used both in estimating sex and the onset of puberty. Changes in the localization of lingula mandibulae according to pubertal development and sex can be used in forensic and anthropological contexts.Öğe In-vivo evaluation of the effects of short-term dehydration and rehydration on the color differences of immature permanent incisor teeth(Wiley, 2024) Buldur, Mehmet; Misilli, Tugba; Sezer, BerkantObjective: It is aimed to evaluate the color changes of upper central incisor teeth with different root maturation levels after 15 min of dehydration and rehydration. Materials and Methods: Using the Cvek classification, 60 participants were divided into five groups. A spectrophotometer, equipped with a specially designed jig, was utilized for color measurements. Following isolation, color measurements were conducted at the dehydration process intervals of baseline, 1st, 2nd, 3rd, 5th, 7th, 10th, and 15th minutes. After mouth rinsing, measurements were repeated at the same time intervals during the rehydration process. CIEDE2000 (Delta E-00) values and the Whiteness Index (WID) were obtained to compare the color changes between the initial readings and each interval. Friedman and Repeated Measures ANOVA were applied to compare classes by time during the dehydration and rehydration periods, as well as ANOVA and Kruskal-Wallis tests to compare by classes for each time (p < 0.05). Results: Significant differences emerged in the mean Delta E-00 values during dehydration and rehydration periods across all Cvek Classes (p < 0.05). While no statistically significant differences were observed among Classes at different minutes during the rehydration period (p > 0.05), it was particularly noted that the mean Delta E-00 values of Classes 2, 3, and 5 at the 2nd minute of dehydration were statistically significantly higher than the mean of Class 1 (p < 0.05). However, when evaluating the starting and ending measurements of both dehydration and rehydration processes, and the overall change in Delta E-00 and Delta WID, no significant variations were detected across the Classes (p > 0.05). Conclusions: In teeth that have just erupted and are still undergoing root development, dehydration in the initial minutes results in noticeable color changes. However, the change in Delta E-00 and Delta WID of the teeth was found to be similar after the dehydration and rehydration processes.Öğe Is there an association between molar incisor hypomineralization and developmental dental anomalies? A case-control study(BMC, 2023) Yavuz, Betuel Sen; Sezer, Berkant; Kaya, Remziye; Tugcu, Nihan; Kargul, BetulBackground The aim of this study was to determine whether there is any association between molar incisor hypomineralization and developmental dental anomalies.Methods Two pediatric dentists evaluated panoramic radiographs of 429 children aged 8-14 years with molar incisor hypomineralization (study group) and 437 children without molar incisor hypomineralization (control group) in terms of developmental dental anomalies. Twelve different developmental dental anomalies were categorized into four types: size (microdontia, macrodontia); position (ectopic eruption of maxillary permanent first molars, infraocclusion of primary molars); shape (fusion, gemination, dilaceration, taurodontism, peg-shaped maxillary lateral incisors); and number (hypodontia, oligodontia, hyperdontia) anomalies.Results No significant difference was observed in the frequencies of developmental dental anomalies between the study and control groups in total, females, and males (p > 0.05). A statistically significant difference was found between the distribution of developmental size, position, shape, and number anomalies between the study and control groups (p = 0.024). The most common anomaly in both groups was hypodontia (6.3% and 5.9%, respectively). There was a significant difference between the study and control groups in terms of subtypes of shape anomaly in all children and females (p = 0.045 and p = 0.05, respectively).Conclusions While a significant difference was observed between the distributions of types of developmental dental anomalies between individuals with and without molar incisor hypomineralization, there was no difference in terms of the frequency of developmental dental anomalies.Öğe İstanbul’da yaşayan bir grup çocuğun büyük azı-kesici hipomineralizasyonu gözlenen dişlerinde lezyon dağılım ve karakteristiklerinin değerlendirilmesi(2023) Sezer, Berkant; Tuğcu, Nihan; Çalışkan, Cansu; Durmus, Basak; Kargül, BetülAmaç: Büyük azı-kesici hipomineralizasyonu (BAKH), etkile- nen dişlerde beyaz/krem rengi ve/veya sarı/kahverengi sınırlı opasiteler, sürme sonrası mine yıkımı, atipik çürük ve restoras- yonların izlendiği gelişimsel bir mine defektidir.

Bulgular: Tüm dişlerde %64,2 oranında BAKH’ye bağlı de- fektler gözlenirken, büyük azı dişlerin etkilenme oranı %85,7, kesici dişlerin etkilenme oranı %53,9 olarak bulunmuştur. En çok etkilenen diş %91,4 oranla sol alt birinci büyük azı diş iken, en az etkilenen diş %41,4 oranla sol alt santral kesici diştir. Lez- yon karakteristikleri açısından kesici dişlerde en sık beyaz/ krem rengi opasiteler, büyük azı dişlerde atipik çürükler göz- lenmiştir. Hastaların %67,1’inde tüm büyük azı dişlerde lezyon tespit edilmiştir. Yaş ile etkilenen büyük azı diş sayısı arasın- da istatistiksel olarak anlamlı bir korelasyon gözlenmezken (p=0,686), kesici diş ve toplam etkilenen diş sayısı ile yaş ara- sında anlamlı bir ilişki olduğu gözlenmiştir (sırasıyla, p=0,003 ve p=0,004). Sonuç: BAKH’nin lezyon dağılım ve karakteristikleri bireyler ve etkilenen dişler arasında değişiklik göstermektedir.Öğe Motivations, attitudes for choosing dental profession and preferred dental specialties amongst Turkish dental students(John Wiley & Sons Ltd, 2022) Sezer, Berkant; Kolay, Duygu; Şen Yavuz, Betül; Güneyligil Kazaz, Tanyeli; Kargül, BetülAim: The aim of the study was to investigate the influential factors for choosing dentistry, their thoughts about the profession, their expectations for the future and their thoughts about the specialisation of dental students from all grades in the School of Dentistry, Marmara University.

It was seen that the students' clinical experience made differences in almost half of their motivational sources for choosing dentistry and their views on future opinions and expectations (p <.05). In addition to clinical experience, gender also made a statistically significant differences in almost all answers in the students' opinions about specialisation (p <.05). Conclusion: From the results of the study, the majority of Turkish dental students were self-motivated compared to familial and environmental factors for choosing dentistry as a career. The career motivations of them seemed to be associated with the socioeconomic aspects of dentistry, whereas the perceptions regarding the future of dentistry seemed to be associated with the need for postgraduate education.
