    Analyzing Content and Information Quality of Instagram® Posts About #teethwhitening
    (Cumhuriyet University Faculty of Dentistry, 2023) Buldur, Mehmet; Misilli, Tuğba; Ayan, Gizem
    Objectives: Getting information on health issues from social media applications provides autonomy to patients; however, different types of content can lead to the development of inappropriate norms. This study therefore aimed to evaluate the content and information quality of Instagram® posts about teeth whitening. Materials and Methods: The first 100 posts were included in the three search periods, which started in October 2022 and were carried out at two-week intervals. (n=300) The #teethwhitening hashtag, which was determined as a trend topic in each search period, was used. The content of the posts was analyzed over eight questions, whereas their general information quality was analyzed according to the modified DISCERN analysis on seven questions. The demographic data of the posts were evaluated in two parts: a) account and b) data of the post. The distribution of the user questions and other hashtags (#) mentioned in the posts were also analyzed. Data normality checked via the Shapiro Wilk test, then applied Mann Whitney U, Kruskal Wallis, Bonferroni tests, and Spearman correlation as needed for non-normal data. Results: 191 posts were excluded from the research. 42% (n=46) of the posts had “low” information content. In addition, the mean value of the content was 2.77 (min 0, max 8/n=109). The mean score in the modified DISCERN score was 11.83 (min 7, max 35/n=109). 53% (n= 57) of the posts were related either to prosthetic treatments alone or to combined treatments that included prosthetic procedures. Most of the posts mentioned the hashtag "#veneer/s". Questions such as cost, duration of treatment, and appointment procedures were also asked as comments under the posts. Conclusions: It can be stated that the content and information quality of Instagram® posts about #teethwhitening are insufficient and may direct patients to more interventional invasive treatment options. © (2023), (Cumhuriyet University Faculty of Dentistry).

    Cross-cultural adaptation of the Turkish version of the dentin hypersensitivity experience questionnaire short form (DHEQ-15)
    (BMC, 2024) Ayan, Gizem; Misilli, Tugba; Buldur, Mehmet
    Background The short form of the Dentin Hypersensitivity Experience Questionnaire (DHEQ-15) is a valid and reliable tool for Oral Health-Related Quality of Life (OHRQoL) studies. The aim of this study was cross-culturally adapt and validate the English version of DHEQ-15 for the Turkish language. Methods The Turkish version of the DHEQ-15 was developed using the forward-backward translation method. Two independent translators translated it from English to Turkish, followed by back-translation into English. A pilot study was conducted with 30 patients with dentin hypersensitivity (DH). The sample consisted of 150 individuals with DH and 150 without. DH was assessed using the Schiff Sensitivity Scale by applying air to the cervical area of the tooth for 1 s from a distance of 1 cm. A total of 300 individuals completed the Turkish DHEQ-15 in the waiting room. Subsequently, 30 randomly selected individuals with DH completed the questionnaire again after 7-10 days to assess test-retest reliability. Participants provided an overall oral health rating assessment on a 6-point scale. The reliability of the DHEQ-15 was assessed using internal consistency and test-retest methods. Exploratory Factor Analysis (EFA) identified its domains, while construct validity was evaluated through cross-cultural (Confirmatory Factor Analysis- CFA), discriminative (Mann-Whitney test) and convergent (Spearman correlation) validity. Results The demographic characteristics of the sample included 137 men and 163 women, with an average age of 36. The Turkish DHEQ-15 demonstrated excellent internal consistency (alpha = 0.970) and outstanding test-retest reliability (r = 0.920, p < 0.001), indicating an excellent correlation. Confirmatory factor analysis confirmed the unidimensional scale structure of the Turkish DHEQ-15 (p = 0.000). A statistically significant negative correlation was found between the DHEQ-15 score and the overall oral health rating assessment (p < 0.05). Participants with DH had a significantly higher DHEQ-15 score compared to those without DH (p < 0.001). Conclusions This study provides evidence supporting the cross-cultural validity and reliability of the Turkish DHEQ-15.

    Evaluation of Plaque Index, Gingival Index and Oral Health-Related Quality of Life in Obese Patients
    (Universidad de Costa Rica, 2023) Ayan, Gizem; Dayı, Burak
    Obesity is a chronic disease that may be related to caries, periodontitis, xerostomia, and dental erosion, as well as increasing morbidity and mortality. The aim of this study was to evaluate the plaque index (Silness & Löe, 1964), the gingival index (Löe & Silness, 1963), and the oral health-related quality of life (OHRQoL) in obese patients. The study included 45 extremely obese, 45 obese, and 45 normal-weight individuals between the ages of 18 and 58. The plaque index and gingival index of the individuals were determined by clinical examination by probing. In addition, the Oral Health Impact Profile-14 (OHIP-14) questionnaire was used for the OHRQoL. The IBM SPSS Statistic 22.0 software program was used for the statistical evaluation of the study data. The plaque index and gingival index values were statistically higher in obese compared to normal weight individuals (p[removed]0.05). There was no statistically significant difference between the OHIP-14 total scores of the groups (p>0.05). Increased apparent plaque index and gingival index values in obese patients may adversely affect periodontal health.

    Home-use agents in the treatment of dentin hypersensitivity: clinical effectiveness evaluation with different measurement methods
    (Springer Heidelberg, 2025) Ayan, Gizem; Misilli, Tugba; Buldur, Mehmet
    Objectives This study aimed to evaluate the effectiveness of home-use desensitizing agents over an 8-week period by comparing them using different measurement methods. Methods A randomized, controlled clinical trial was conducted with 180 individuals aged between 18 and 70 who clinically diagnosed dentin hypersensitivity (DH) in two or more non-adjacent teeth. Subjects who met the inclusion criteria (n = 164) were randomly allocated into five test groups-using Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), Arginine, Novamin, Propolis, and Potassium nitrate-and a control group using standard fluoride toothpaste. The status of DH was assessed at week 4 and week 8 by the same independent examiner. Changes from baseline in Dentine Hypersensitivity Experience Questionnaire-15 (DHEQ-15), Schiff Sensitivity Scale (SSS) and Visual Analog Scale (VAS) were analysed using ANOVA and Kruskall-Wallis tests. Results All test groups showed statistically significant improvements in DH at weeks 4 and 8 compared to baseline in the DHEQ-15, VAS, and SSS assessments (p < 0.005). In the control group, significant improvements were observed only in the VAS and SSS measurements from baseline to weeks 8 (p < 0.005). The CPP-ACP group demonstrated the greatest reduction in scores by the end of week 8 compared to baseline, with DHEQ-15 (56.68 +/- 17.87), VAS (6.52 +/- 1.48), and SSS (2.32 +/- 0.56). Conclusions Among the tested agents, the CPP-ACP group demonstrated the most notable reduction in DH symptoms by week 8, highlighting its potential as an effective method for alleviating DH symptoms in a home-use agents. Clinical relevance Home-use desensitizing agents are effective in the treatment of DH, improving the daily activities of patients who cannot access clinical care and ensuring the relief of DH before clinical invasive procedures.

    Investigation of DMFT Index and Saliva Values in Morbidly Obese and Obese Patients
    (Duzce Univ, Fac Medicine, 2023) Ayan, Gizem; Dayi, Burak; Sahin, Selale; Evren, Bahri
    Objective: Obesity is a global chronic disease that affects both developed and developing countries. The purpose of this study was to examine the effect of morbid obesity and obesity on the decayed, missing, and filled teeth (DMFT) index and saliva values. Method: This study included 50 morbidly obese, 50 obese, and 50 control group patients aged 18-68 years. The DMFT index of the patients was determined through a clinical examination. The saliva kit was used to determine the saliva values [unstimulated saliva flow rate (USFR), stimulated saliva flow rate (SSFR), saliva viscosity (SV), saliva pH (SpH), and saliva buffering capacity (SBC)]. The patients were surveyed to learn about their oral health habits, nutritional habits, and socioeconomic status. Results: No significant difference was found in the number of decayed teeth, filled teeth, USFR, or SV between the groups (p > 0.05). The DMFT index, number of missing teeth, SSFR, SpH, and SBC all showed significant differences between the groups (p < 0.05). The significant variables associated with DMFT, according to the multiple linear regression model, were the frequency of dental visits (f3 = 0.365), age (f3 = 0.322), and SSFR (f3 = -0.256). Conclusion: Obese patients have a low saliva rate, low saliva pH, low buffering capacity, high DMFT index, and a high number of missing teeth.

    Tıp Fakültesi Öğrencilerinin Ağız-Diş Sağlığına İlişkin Bilgi, Tutum ve Davranışlarının Değerlendirilmesi
    (2023) Ayan, Gizem; Misilli, Tuğba; Buldur, Mehmet; Örcünlü, Orçun Alp; Taner, Hüseyin
    Amaç: Genel sağlığın ayrılmaz bir parçası olan ağız-diş sağlığının korunmasında diş hekimlerine olduğu kadar tıp hekimlerine de büyük görev düşmektedir. Bu çalışmanın amacı tıp fakültesi 1. sınıf ve 6. sınıf öğrencilerinin ağız-diş sağlığına ilişkin bilgi, tutum ve davranışlarını değerlendirmektir. Gereç ve Yöntemler: Çalışmaya Çanakkale Onsekiz Mart Üniversitesi Tıp Fakültesi’nde öğrenim gören 112 1. sınıf ve 92 6. sınıf öğrencisi dahil edilmiştir. Tıp fakültesi öğrencilerine ağız-diş sağlıklarına ilişkin bilgi düzeyleri ve oral hijyen alışkanlıklarını değerlendirmek amacıyla 23 sorudan oluşan anket formu online olarak gönderilmiştir. İstatistiksel analizde Frekans ve Ki-kare analizleri kullanılmış, p<0,05 istatistiksel olarak anlamlı kabul edilmiştir. Bulgular: Tıp fakültesi öğrencilerinin öğrenim yılı ile diş hekimine gitme sıklığı (p=0,011), ağız-diş sağlığı ile ilgili eğitim alma durumu (p=0,023), diş çürüklerinin ve fırçalama sırasında dişeti kanamasının olası nedenleri (p<0,001), diş plağının etkileri (p=0,014), ağız hastalıklarıyla ilişkili olabilecek sistemik hastalıklar ve diş hekimi konsültasyonu gerektiren hasta gruplarına verdikleri yanıtlar (p<0,001) arasında anlamlı ilişki bulunmuştur. Tıp fakültesi öğrencileri, ağız-diş sağlığıyla ilgili en sık diş hassasiyeti, diş çürüğü ve dişeti kanaması problemleri yaşadıklarını belirtmişlerdir. Sonuç: Tıp fakültesi eğitimi, öğrencilerin ağız-diş sağlığıyla ilgili bilgi düzeylerinde olumlu anlamda bir katkı sağlasa da bunun yeterli düzeyde olmadığı görülmektedir. Koruyucu diş hekimliği alanında hekimlerin rolünün anlaşılabilmesi için ağız ve diş sağlığı konusunun tıp eğitimi müfredatında yer almasının faydalı olacağı düşünülmektedir
