    Accuracy of different dental age estimation methods for determining the legal majority of 18 years in the Turkish population
    (Springer Heidelberg, 2022) Akman, Hayri; Surme, Koray; Cimen, Tansu; Ayyildiz, Halil
    Objectives Radiographic evaluation of the third molar maturation is used to estimate dental age, especially in adolescence. This study aimed to assess the application of three age estimation methods (Cameriere's third molar maturity index (I-3M), Demirjian's maturation stages, and The London Atlas) to determine whether an individual is 18 years or older (adult) or younger than 18 years (minor). Materials and methods The dental age was estimated using the I-3M, Demirjian's maturation stages, and The London Atlas methods on panoramic radiograms of a total of 500 Turkish individuals aged 14-22 years. A logistic model was derived with an individual's adult or minor status as the dependent variable, and each method and sex as predictive variables. The adult status was determined using dental age estimation methods and the performance of these methods in differentiating adults from minors was evaluated. The three methods were compared case-wise for their accuracy in predicting adult status. Results Logistic regression analysis showed that sex and each estimation method were statistically significant in discriminating adults and minors (p < 0.05). In the case-wise comparison for estimate adulthood, both Demirjian's stages and I-3M methods tended to perform better than the London Atlas method, with this trend reaching statistical significance (p < 0.05). Conclusions Cameriere's I-3M and Demirjian's development stages are useful methods for adult age assessment in the tested population.

    CAN THE SELF-ADHESIVE FLOWABLE COMPOSITE BE SECURELY BONDED TO PRIMARY TOOTH ENAMEL?
    (Serban Solacolu Foundation, 2021) Akman, Hayri; Surme, Koray; Akin, Mehmet
    This study evaluated the shear bond strength of self-adhesive flowable composite when used with acid etching or a self etch adhesive system. Buccal enamel surfaces on 80 extracted human primary incisors were used and randomly assigned into four groups (n=20); group 1: Vertise (TM) Flow; group 2: Vertise Flow with acid etching; group 3: Vertise Flow with a self-etching bonding agent; group 4: Premise FlowableTM with a total-etch bonding agent as the control group. After 5000 rounds of thermocycling, the bond strength test was performed using a universal testing machine at a crosshead speed of 0.5 mm/min. The fracture analyzes of samples were evaluated using a light stereomicroscope. The results obtained were analyzed via analysis of variance (ANOVA) and Tukey's tests. Statistically significant differences were observed among all groups (P<0.001). Group 1 generated a lower mean shear bond strength (2.63 +/- 1.08 MPa) than those of the other groups [group 2 (7.52 +/- 2.14 MPa), group 3 (5.12 +/- 2.93 MPa), and group 4 (14.18 +/- 2.93 MPa)]. Adhesive failure was the most common failure mode in Vertise Flow groups. Vertise Flow used with a self-etching agent or acid etching exhibited in lower shear bond strength than the control group.

    (Spemd-Soc Portuguesa Estomatologia & Medicina Dentaria, 2023) Ozkan, Hatice Buyukozer; Surme, Koray; Akman, Hayri; Er, Kursat
    Objectives: To compare the cyclic fatigue resistances of MicroMega Remover, EndoArt, and ProTaper nickel-titanium retreatment files when used in curved artificial canals.Methods: A total of 45 new C-wire Remover, controlled-memory wire EndoArt D2, and non heat-treated NiTi ProTaper D2 retreatment files, 15 per group, were tested in a stainless-steel block containing an 18-mm-long artificial canal with curvature in the apical third, an inner diameter of 1.5 mm, a curvature angle of 60 degrees, and a radius of curvature of 5 mm. The experimental system was filled with distilled water, and the ambient temperature was kept constant at 35 +/- 1 degrees C. The retreatment files were rotated until fracture to calculate the number of cycles to failure. The length of each fractured fragment was recorded. The number of cycles to failure and the fragment length values were analyzed using one-way analysis of variance (ANOVA) and Tukey post-hoc tests. The statistical significance level was set at p<0.05.Results: The group with the highest number of cycles to failure values was EndoArt D2 (1401.33 +/- 279.00), followed by MicroMega Remover (950.07 +/- 195.84) and ProTaper D2 (341.87 +/- 48.12), with a statistically significant difference between all file systems tested (p<0.05). No difference was observed among the retreatment files regarding the lengths of fractured fragments.Conclusions: The EndoArt D2 file exhibited greater cyclic fatigue resistance than the MicroMega Remover and ProTaper D2 files.

    Background The aim of this study was to compare the cyclic fatigue resistance (CFR) of the newly developed pediatric nickel-titanium (NiTi) rotary file systems for root canal preparation of primary teeth. Methods Eighty pediatric NiTi rotary file systems files were used in this study, including 20 EasyInSmile X-Baby (25/0.04), 20 Scope miniScope (25/0.04), 20 EndoArt Pedo Gold (25/0.04), and 20 EndoArt Pedo Blue (25/0.04) files. Static CFR tests; performed on a custom-made stainless steel block with an inner diameter of 1.5 mm, an angle of curvature of 60 degrees and a curved artificial canal with a radius of curvature of 5 mm. The test system was filled with distilled water and the temperature was kept constant at 35 +/- 1 degrees C. The files were rotated in the simulated canal until fracture occurred. The number of cycles to failure (NCF) data was recorded, and all the fracture surfaces of the files were evaluated using scanning electron microscopy (SEM). One-way ANOVA and Tukey tests were used for statistical analysis of the data, and the significance level was set at p < 0.05. Results EndoArt Pedo Blue showed the highest NCF values (2668.10 +/- 755.26), while the miniScope showed the lowest NCF values (453.65 +/- 72.51), with a statistically significant difference between all the tested file systems (p < 0.05). There was no statistical difference in terms of fractured fragment lengths among all tested files (p > 0.05). Conclusion The EndoArt Pedo Blue file system showed the best CFR performance among the four file systems specifically designed for primary teeth.

    (Quintessence Publishing Co Inc, 2021) Surme, Koray; Akman, Hayri; Akbaydogan, Leyla Cime; Akin, Mehmet
    Purpose: The coronavirus disease 2019 (COVID-19) pandemic is a major public health crisis worldwide and it also has generated new challenges for dentistry. The aim of this study was to evaluate the knowledge and attitudes of the parents of pediatric patients about dental treatment during the COVID-19 pandemic through a questionnaire. Materials and Methods: A structured questionnaire consisting of 15 multiple-choice questions and demographic information about the knowledge and attitudes of parents regarding dental treatment during the COVID-19 outbreak was used for the study. The participants were parents of pediatric patients (aged 8-14 years) who visited for a routine orthodontic examination at the department of orthodontics. Results: A total of 250 participants responded to the questionnaire. The findings indicate that more than 95% of parents had information about the transmission paths of the virus, took COVID-19 seriously, and told their children about this disease. 34% of the parents thought that dental clinics were more dangerous than other social areas, and 39.2% thought their children could be infected by medical instruments during dental treatment. A statistically significant difference was observed between educational levels in the answers given about the transmission paths of the virus, the danger of dental clinics in terms of the virus, the permitted dental treatment procedures, and the personal protective equipment of the dentist (p < 0.05). Conclusion: Although most parents have information about COVID-19, there are differences in the knowledge and attitudes of parents during the pandemic period according to their educational level.

    (Springernature, 2023) Surme, Koray; Akman, Hayri
    BackgroundDental students are expected to play a critical role in the oral health education of society as future providers of dental care, and their attitudes on this subject have a possible impact on the awareness of patients regarding the importance of preventing oral diseases and improving oral health. This study aimed to evaluate the oral health attitudes and behavior of dental students.MethodologyThe Turkish version of the Hiroshima University Dental Behavior Inventory (HU-DBI) questionnaire regarding oral health attitudes and behaviors with an additional nine questions was distributed among 250 native Turkish-speaking dental students at the Faculty of Dentistry in Antalya, Turkey. The validity of the nine questions added to the original questionnaire was evaluated by expert opinion and a pretest method. A self-administered questionnaire was used for data collection. The Mann-Whitney U test and chi-square test were used for statistical analysis, and the statistical significance level was set at p-values <0.05.ResultsThe mean age of the 250 students in the study was 20.96 +/- 1.66 years. In total, 157 (62.8%) students were preclinical (first, second, and third year) dentistry students, and 93 (37.2%) students were clinical (fourth and fifth year) dentistry students. The mean HU-DBI score of all students was 5.95 +/- 1.65, and the mean HU-DBI score of clinical students (6.42 +/- 1.65) was significantly (p < 0.05) higher than that of preclinical students (5.67 +/- 1.59). The mean HU-DBI score of male and female students was 5.63 +/- 1.55 and 6.24 +/- 1.69, respectively, and this difference was statistically significant (p < 0.05). The study showed significant improvement in the behavior and attitude regarding the oral health of the clinical dental students compared with the preclinical dental students.ConclusionsAmong dental students, clinical students and female students had generally better attitudes and behaviors about oral health self-care compared to preclinical students and male students, respectively.

    The Turkish version of Caries Impacts and Experiences Questionnaire for Children: Translation, reliability, and validity
    (Wiley, 2024) Surme, Koray; Akman, Hayri
    Background: Caries Impacts and Experiences Questionnaire for Children (CARIES-QC) has been developed to assess the oral health-related quality of life (OHRQoL) associated with caries.Aim: This study aimed to evaluate the validity and reliability of the CARIES-QC in the Turkish-speaking population following its translation and adaptation into Turkish (CARIES-QC/T).Design: Two hundred and fifty children between the ages of 5 and 16 years who have active dental caries were included in the study and answered the Turkish-translated and cross-culturally adapted final version of CARIES-QC/T. Test-retest reliability and internal consistency were used to examine the reliability of the CARIES-QC/T. Factor structure of CARIES-QC/T was analyzed using exploratory factor analysis (EFA), and convergent validity was determined.Results: Cronbach's alpha and McDonald's omega values were 0.907 and 0.908, respectively. For the CARIES-QC/T scale, the intraclass correlation coefficient (ICC) value was 0.933, and polychoric correlations ranged from 0.390 to 0.794. The convergent validity of the items revealed a statistically significant correlation with the global question (rs = 0.821, p < .001). The EFA results of CARIES-QC/T suggested a one-factor solution and explained 59.7% of the total variance.Conclusion: The findings provided supporting evidence that the CARIES-QC/T could be used as a tool for measuring OHRQoL in healthy Turkish-speaking children aged 5-16 years with active caries.
