Öğe A Comparison of the Effectiveness of Combined Primer and Adhesive Systems in Orthodontic Bonding: An In Vitro Study(Mdpi, 2025) Uslu, Filiz; Gunes, Tugce Esra; Akin, Mehmet; Akman, HayriBackground: Adhesive systems are important for achieving reliable and durable bracket bonding in orthodontic treatments. The purpose of this study is to compare the outcomes of a new one-step orthodontic bonding system that combines the primer and adhesive solutions. Methods: In this study, four groups were formed, each consisting of 20 first premolar teeth. Acid etching was applied to all teeth for 30 s, except in Group II. Group I included teeth where a single layer of primer was applied using the Transbond XT system before bracket bonding. Group II consisted of teeth bonded with brackets after using a self-etching primer with the Transbond XT system. Group III used GC Ortho Connect, a single-step adhesive that incorporates the primer within the adhesive itself. Group IV, a single layer of primer was applied before bonding with GC Ortho Connect. Shear bond strength (SBS) was assessed using one-way ANOVA and the Tukey-HSD test, while Adhesive Remnant Index (ARI) scores were analyzed using the Chi-square test at a significance level of p < 0.05. Results: SBS measurements were recorded as 13.28 +/- 2.15 MPa for Group I, 11.06 +/- 2.26 MPa for Group II, 10.37 +/- 1.92 MPa for Group III, and 16.02 +/- 2.17 MPa for Group IV. Statistical analysis using the Tukey test revealed significant differences in SBS values between Groups II and IV, as well as Groups III and IV (p < 0.05). All groups showed clinically acceptable bond strength, with Group IV demonstrating superior adhesion. Additionally, the chi-square test indicated a statistically significant variation in the ARI scores across all four groups (p < 0.05). Conclusions: The adhesive performance of the one-step GC Ortho Connect system is clinically comparable to Transbond XT. However, primer application is necessary to achieve optimal bond strength.Öğe 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, HalilObjectives 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.Öğe Bilgilendirici Broşür Uygulamasının Travmatik Diş Yaralanmaları Hakkında Ilkokul Öğretmenlerinin Bilgi Seviyesine Etkisinin Değerlendirilmesi(2021) Sürme, Koray; Akman, HayriÇalışmamızın amacı Alanya bölgesindeki ilkokul öğretmenlerinin travmatik diş yaralanmasında acil durum yönetimi konusunda bilgi düzeylerini belirlemek ve bilgilendirici broşürün etkinliğini değerlendirmektir.Bu çalışmaya, Alanya’da görev yapmakta olan 250 ilkokul öğretmeni katılmıştır. Demografik bilgiler ve travmatik diş yaralanmalarında acil durum yönetimi ile ilgili sorulardan oluşan anket formları dağıtılarak öğretmenlerin yanıtlamaları istenmiştir. Anketler cevaplandıktan sonra, öğretmenlere tarafımızca hazırlanmış diş yaralanmalarında acil durum yönetimi hakkında bilgiler içeren broşürler dağıtılmıştır. İki hafta sonra aynı öğretmenler anketleri yeniden cevaplamışlardır.Çalışmaya katılan 250 öğretmenin 235’i her iki anketi de eksiksiz cevaplamıştır. Ankette bulunan 9 bilgi sorusuna öğretmenlerin verdiği her doğru cevap 1 puan ve her yanlış cevap 0 puan olarak değerlendirilmiştir. İlk yapılan anketlerde öğretmenlerin ortalama doğru cevap puanları 4.74 iken bilgilendirme broşürü sonrasında yapılan anketlerde öğretmenlerin ortalama doğru cevap puanları 7.89’a çıkmıştır ve iki puan arasında istatistiksel olarak anlamlı derecede fark vardır (p<0.0001).Çalışmamızdan elde edilen veriler öğretmenlerin travmatik diş yaralanmaları konusundaki bilgi düzeylerinin yeterli olmadığını göstermektedir. Dental travmaların okullarda çok sık görülmesi sebebiyle öğretmenlerin acil durum yönetimi hakkında daha fazla bilgi sahibi olması gerekmektedir. Travmatik diş yaralanmalarında öğretmenlerin acil durum yönetimi konusunda bilgi düzeylerinin artırılması için bilgilendirici broşür kullanımı faydalı olabilir.Öğe Can the self-adhesive flowable composite be securely bonded to primary tooth enamel?(Fundatia Serban Solacolu, 2021) Akman, Hayri; Sürme, Koray; Akın, MehmetThis 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™ Flow; group 2: Vertise Flow with acid etching; group 3: Vertise Flow with a self-etching bonding agent; group 4: Premise Flowable™ with a total-etch bonding agent as the control group.

Materials and Methods: A total of 160 class II carious lesions (with radiographic involvement of the outer half of dentin) in 30 patients were randomly divided into four groups and restored with a glass ionomer restorative system (Equia (TM)), two different bulk-fill composites (Sonicfill (TM) and X-tra fil (TM)), and a nanohybrid composite (Filtek Z550 (TM)). The restorations were clinically and radiographically evaluated at the baseline, and 3, 6, and 12 months according to the modified United States Public Health Service criteria. Statistical analyses were performed using Pearson's Chi-square and McNemar tests. Results: After 1 year, 134 restorations were evaluated in 26 patients. Equia was statistically less successful than the other restorative materials in marginal adaptation and retention criteria (P < 0.05). However, no material was found to be superior to the others over the study period in marginal discoloration, color matching, secondary caries, anatomical form, and postoperative sensitivity (P > 0.05). Conclusion: The bulk-fill and conventional composites exhibited good clinical performance, and Equia exhibited minor changes over the 1-year trial period.Öğe Comparison of cyclic fatigue resistance between heat-treated and conventional retreatment files(Spemd-Soc Portuguesa Estomatologia & Medicina Dentaria, 2023) Ozkan, Hatice Buyukozer; Surme, Koray; Akman, Hayri; Er, KursatObjectives: 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.

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.Öğe Effects of Early Unilateral Mandibular First Molar Extraction on Condylar and Ramal Asymmetry(2023) Sürme, Koray; Akman, Hayri; Çimen, Tansu; Akın, MehmetSUMMARY: Craniofacial symmetry is an important factor in creating a harmonious facial appearance. Genetic and external factors may cause the formation of mandibular asymmetry. The aim of this study was to evaluate vertical mandibular asymmetries in adolescents who had unilateral mandibular first permanent molar (FPM) teeth extracted at an early age. The study group consisted of 60 subjects (30 females, 30 males with a mean age of 16.18±1.04 years) who had their mandibular permanent first molar tooth extracted before the age of 12, and the control group consisted of 60 healthy subjects (30 females, 30 males with a mean age of 16.23±0.92 years). Condylar asymmetry index (CAI), ramal asymmetry index (RAI), and condylar-ramal asymmetry index (CRAI) were calculated using panoramic radiographs of the subjects. Independent samples t-test was used to evaluate the differences between groups. CAI, RAI, and CRAI values were similar between male and female subjects in both control and study groups, and no statistically significant difference was found (p>0.05). No statistically significant difference was observed between the group who had their mandibular first permanent molar teeth extracted at an early age and the control group (p>0.05). CAI values were relatively higher in both groups, but there was no significant difference between the CAI, RAI, and CRAI values between the groups.Öğe Effects of er:YAG laser treatment on the mineral content and morphology of primary tooth enamel(Mary Ann Liebert Inc., 2018) Kahvecioğlu, Firdevs; Kahraman, Kamil; Akman, Hayri; Tosun, GülObjective: The aim of this study was to evaluate the mineral content and morphology of primary tooth enamel prepared using an Er:YAG laser at different power settings. Materials and methods: The buccal surfaces of 45 noncarious primary molars were assessed in this study. The surfaces were cleaned and the teeth were randomly divided into nine groups (n = 5 each) to evaluate the effects of Er:YAG laser treatment at different energy levels: 200 mJ, 2 Hz; 200 mJ, 3 Hz; 200 mJ, 10 Hz; 250 mJ, 2 Hz; 250 mJ, 3 Hz; 250 mJ, 10 Hz; 300 mJ, 2 Hz; 300 mJ, 3 Hz; and 300 mJ, 10 Hz. The mean percentage weight (wt%) of calcium (Ca), phosphorous (P), fluoride (F), magnesium (Mg), potassium (K), and sodium (Na) in the primary tooth enamel was calculated for each group using scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy before and after laser application. The enamel morphology was also evaluated using SEM. The obtained data were statistically analyzed by one-way analysis of variance and Tukey's honest significant difference test. Results: The mean wt% of Ca, P, and F in the enamel exhibited a significant change after laser treatment (p < 0.05); the wt% of Mg, K, and Na remained unchanged (p > 0.05). There was no association between the power setting of the laser and changes in the wt% of minerals in the enamel (p > 0.05). SEM showed that enamel irradiated at different energy levels exhibited a characteristic lava flow appearance, and more surface irregularities were observed with the 250-mJ setting than with the 200-mJ setting. Conclusions: Our findings suggest that the mineral content and morphology of the enamel of primary teeth are affected by Er:YAG laser irradiation. © Copyright 2018, Mary Ann Liebert, Inc., publishers 2018.Öğe Evaluation of Parents' Knowledge and Attitudes Towards Pediatric Dental Practice during the COVID-19 Pandemic(Quintessence Publishing Co Inc, 2021) Surme, Koray; Akman, Hayri; Akbaydogan, Leyla Cime; Akin, MehmetPurpose: 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.Öğe Evaluation of Self-Reported Oral Health Attitudes and Behavior of Dental Students in Antalya, Turkey(Springernature, 2023) Surme, Koray; Akman, HayriBackgroundDental 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.

The success of an adequate and effective nerve block with this technique depends on deposition of local anesthetic solution near mandibular foramen (MF), located on the medial side of mandibular ramus. Objectives: The purpose of the study was to investigate the relative position of MF using digital panoramic radiographic technique to provide data for IANB technique in children. Material and methods: This retrospective study consisted of digital panoramic radiographs from 200 children, aged 5-14 years. Panoramic radiographs were divided into 5 groups according to Hellman dental classification. The distance of MF to occlusal plane, anterior border of the ramus, and lower border of the mandible were measured using computer software in different age groups, and then compared to determine the position of MF on radiographs. One-way analysis of variance test, which is one of the parametric tests, was used to compare mean values between the groups. Results: While MF was 0.85 mm above the occlusal plane in Hellman IIC age group, this distance increased with age progression, and there was a statistically significant difference between age groups. The distance from MF to anterior edge of the ramus and lower plane of the mandible increased in Hellman IVA age group, and there was a statistically significant difference between age groups. Conclusions: The position of MF in panoramic radiographs gradually changed posteriorly and upwards on the ramus with age progression. © 2021 Polish Dental Association.Öğe Retrospective analysis of ferric sulfate and sodium hypochlorite pulpotomy procedures in primary molars(Tabriz University of Medical Sciences, 2023) Akman, Hayri; Sürme, KorayBackground. Pulpotomy is a vital pulp treatment procedure frequently used in primary molars to preserve pulp vitality and function until tooth exfoliation. There is currently no pulp medicament with all the features of the ideal pulpotomy material. The present study compared the radiographic success of sodium hypochlorite with ferric sulfate (FS) when used for pulpotomy in primary molars. Methods. A retrospective analysis was performed to evaluate the success rates of primary molars pulpotomized using sodium hypochlorite or FS according to radiographic findings. Healthy 4?10-year-old children who had pulpotomy procedures on primary molars between 2018 and 2021 at the pediatric dental clinic and had a control radiograph at least 12 months later were enrolled in the study. The chi-squared test was used to determine the differences in success between these two materials. Results. A total of 142 teeth, including 85 (59.9%) first primary molars and 57 (40.1%) second primary molars, in 98 healthy children were evaluated. The mean follow-up period of the teeth included in the study was 585.1 ± 249.4 days. Radiographic success rates for NaOCl and FS groups were 73.8% and 71.0%, respectively, with no statistically significant difference (P > 0.05). Internal root resorption (IRR) was the most common cause of radiographic failure in both groups. Conclusion. Radiographic success rates of both materials were similar, and using these materials in primary molar pulpotomy procedures can be recommended in clinical practice. © 2023 The Author(s).Öğe The Turkish version of Caries Impacts and Experiences Questionnaire for Children: Translation, reliability, and validity(Wiley, 2024) Surme, Koray; Akman, HayriBackground: 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.
