    Color stability of a novel self-cure bulk-fill composite compared to light-cure bulk-fill and injectable composite resins
    (Bmc, 2025) Carikcioglu, Burak; Ay Simsek, Idil; Arikan, Volkan; Sariyilmaz, Evren
    ObjectiveThis study aimed to assess the color stability of a novel self-cure bulk-fill composite (automix and capsule forms), in comparison to a light-cure bulk-fill composite and a conventional flowable composite after immersion in common beverages. Materials and methodsFour composite resins (Stela Automix, Stela Capsule, Filtek Bulk Fill Flowable, and G-ae nial Universal Injectable) were evaluated on 160 disc-shaped specimens. Specimens were randomly assigned to four subgroups (n = 10) and immersed in tea, coffee, cola, or distilled water (control). Color measurements were performed using a spectrophotometer at baseline, 6 and 12 days, and color changes (Delta E-0(0)) were calculated using the CIEDE2000 formula. Statistical analyses were performed using one-way ANOVA with Tukey's post-hoc tests and paired sample T-tests to evaluate time-dependent changes (p < 0.05). ResultsAll composites showed increased discoloration over time, with coffee causing the most significant color change, followed by cola, while tea had a milder effect. Self-cure bulk-fill composites showed significantly higher Delta E-0(0) values than their light-cure composites. Stela Automix showed the greatest color change after Stela Capsule. ConclusionThe results suggest that self-cure bulk-fill composites have lower color stability than light-cure composites. Filler characteristics, particularly particle size and loading, have a greater influence on color stability than resin matrix composition.

    Dental age estimation with fewer than mandibular seven teeth: An accuracy study of Bedek models in Turkish children
    (Springer Heidelberg, 2022) Carikcioglu, Burak; Sezer, Berkant
    Objectives 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.

    Evaluation of the accuracy of Nolla, Cameriere-European, and Blenkin-Evans methods for dental age estimation of Turkish children
    (Sage Publications Inc, 2025) Carikcioglu, Burak; Sezer, Berkant
    Dental age (DA) estimation plays a crucial role in forensic investigations, clinical diagnosis, and treatment planning. It is considered more reliable than skeletal methods due to the predictable nature of dental development. This study aimed to evaluate the accuracy of three DA estimation methods-Nolla method, Cameriere-European formula, and Blenkin-Evans method-in Turkish children aged 6-14 years. A total of 1014 panoramic radiographs were analyzed. DA was estimated using the three methods and compared with chronological age (CA). Accuracy was assessed based on mean absolute error (MAE), mean difference (DA-CA), and correlation coefficients. Statistical analyses were performed to determine significant differences among methods. The Cameriere-European formula demonstrated the lowest MAE (0.44 for boys, 0.48 for girls, and 0.46 for all samples), indicating the highest accuracy, followed by the Blenkin-Evans (0.54 for boys, 0.53 for girls, and 0.54 for all samples) and Nolla (0.57 for boys, 0.65 for girls, and 0.61 for all samples) methods. However, the Cameriere-European formula slightly underestimated CA, particularly in older children. The Blenkin-Evans method showed relatively stable accuracy but overestimated CA in both sexes. The Nolla method generally underestimated CA, except in boys, where it slightly overestimated age. All three methods exhibited strong correlations with CA (Spearman rho correlation coefficients ranging from 0.953 to 0.970, all p < .001). The Cameriere-European formula provided the most accurate DA estimation method, followed by the Blenkin-Evans and Nolla methods for Turkish children from the Northwestern Anatolia. However, the observed biases highlight the need for population-specific calibrations.

    Impact of Biodentine Placement on Fracture Resistance and its Influence on Discoloration with Different Scaffolds
    (Elsevier Science Inc, 2025) Sariyilmaz, Evren; Sariyilmaz, Oznur; Carikcioglu, Burak; Uslu, Gulsah; Alan, Raif
    Introduction: This study aimed to investigate the fracture resistance of teeth that underwent ex vivo regenerative endodontic treatment using Biodentine placed either above or below the cemento-enamel junction (CEJ). Additionally, it examined the impact of different placement approaches, in combination with various scaffold materials (blood, platelet-rich fibrin [PRF], injectable PRF [i-PRF]), on tooth discoloration over time. Methods: Thirty-nine human maxillary incisors were divided into three groups. The control group consisted of intact teeth. In the two experimental groups, regenerative endodontic procedures were simulated, and Biodentine was placed above or below the CEJ. Fracture resistance was evaluated after thermal and mechanical aging using a chewing simulator. In the discoloration test, 96 human maxillary incisor teeth were selected. Roots were sectioned 10 mm apical to the CEJ and canal enlargement was performed Gates-Glidden burs. Teeth were grouped according to the placement level of Biodentine (above or below CEJ) and the type of scaffold materials used (blood, PRF, i-PRF, distilled water). Discoloration was assessed by using a spectrophotometer at baseline, 1 week, 1 month, and 6 months. Data were analyzed using one-way analysis of variance followed by Tukey post hoc tests independent t-tests were used to evaluate the effect of placement location on color change. Results: The fracture resistance of intact teeth was significantly higher than that of the group in which Biodentine was placed below the CEJ. Blood and blood-derived products resulted in greater discoloration compared to distilled water, whereas PRF induced less discoloration than blood. Furthermore, the placement of Biodentine above the CEJ led to significantly less discoloration at specific time points compared to its placement below the CEJ. Conclusions: Positioning Biodentine above the CEJ may offer clinical advantages by potentially improving structural integrity while minimizing aesthetic concerns. When PRF is used as the scaffold material and Biodentine is placed coronally, tooth discoloration is minimized. (J Endod 2025;51:1199-1206.)

    Impact of parental dental anxiety on the oral health-related quality of life of preschool children without negative dental experience
    (Elsevier France-Editions Scientifiques Medicales Elsevier, 2022) Carikcioglu, Burak
    Background: Oral health-related quality of life (OHRQoL) is negatively affected by negative dental experiences. It is unclear how parental dental anxiety affects the OHRQoL of children who have not had a negative dental experience. Thus, this study aimed to investigate the impact of parental dental anxiety on the OHRQoL of preschool children without negative dental experiences. Methods: This cross-sectional study enrolled 412 parents of preschoolers aged 4-6 years. The parents answered a questionnaire on sociodemographic status, negative dental experience, dental anxiety, and perception of their children's OHRQoL (Early Childhood Oral Health Impact Scale, ECOHIS). Children with negative dental experiences were not included in the study. Results: An increase in parental dental anxiety was found to have a negative impact on OHRQoL (p<0.05). The adjusted model showed that at all levels of parental dental anxiety, the sex and age of the children, as well as the parents' educational level had no impact on OHRQoL (p>0.05). Furthermore, at all levels of parental dental anxiety, regular dental visits by children had the greatest negative impact on the OHRQoL (p<0.001). Conclusion: This study revealed that an increase in parental dental anxiety as well as dental visits negatively affected the OHRQoL of preschoolers without a negative dental experience.

    The impact of remineralization agents on dental bleaching efficacy and mineral loss in bleached enamel
    (Wiley, 2022) Misilli, Tugba; Carikcioglu, Burak; Deniz, Yesim; Aktas, Cagatay
    This study evaluated the effect of remineralization agents on bleaching efficiency, enamel mineral changes, and post-bleaching color stability. A total of 112 enamel-dentin blocks were prepared from bovine teeth. Following initial color measurements, separate treatment regimens were carried out as follows: negative control (no treatment); positive control (bleaching only); bleaching, then NaF; bleaching + NaF (mix); bleaching, then CPP-ACPF; bleaching + CPP-ACPF (mix); bleaching, then nHAP+F; bleaching + nHAP+F (mix). Color measurements were repeated after immersion in distilled water for 7 days, and again after staining with coffee solution for 14 days. The CIELAB-based whiteness index was used to evaluate bleaching efficiency, and the CIEDE2000 color difference formula for color stability. Chemical investigation was performed using scanning electron microscopy with energy dispersive spectroscopy and X-ray diffraction analyses. The experimental groups showed significant increases in whiteness compared to the negative control, and the staining after bleaching did not result in statistically significant differences between the groups. Energy dispersive spectroscopic analysis revealed that bleaching protocols had no impact on elemental levels as well as the ratio of Ca/P. The combined use of bleaching agents with remineralization agents did not affect bleaching effectiveness but also did not provide an additional contribution.
