(2020) Gulsahi, Ayse; Cehreli, Sevi Burcak; Galic, Ivan; Ferrante, Luigi; Cameriere, Roberto; 31915966
This study aimed to test radiographic projections of the posterior and anterior sides of the C4 vertebral body for age estimation in a cross-sectional sample of Turkish children and adolescents from the Baskent University Faculty of Dentistry. A sample of 232 x-rays from individuals aged between 5 and 15 years (101 boys and 131 girls) was analysed to investigate the correlation of age and changes in the projection ratio of the anterior and posterior sides of the body of the fourth cervical vertebra (Vba) in lateral cephalograms. The Normal Bayesian Calibration (NBC) model for age estimation was used to assess the relationship between Vba and age. The intra-observer repeatability and inter-observer agreement were 0.95 and 0.94, respectively. Age distribution gradually increased as Vba increased up to 14 years in both sexes. The difference between chronological and estimated ages did not increase with the increase in age. Calibration distributions of the dataset by the evaluation of Vba suggested mean absolute errors (MAEs) of 0.879 years and 0.906 years (mean interquartile ranges (MIQRs) 1.290 and 1.435 years)) in boys and girls, respectively. The biases of the estimates (beta(ERR)) were 0.013 and 0.027 for boys and girls, respectively. In conclusion, the NBC method on Vba variable appears to be suitable for age estimation in Turkish children and adolescents.

(2018) Dogru, Hatice Boyacioglu; Gulsahi, Ayse; Cehreli, Sevi Burcak; Galic, Ivan; van der Stelt, Paul; Cameriere, Roberto
Radiological examination of the third molar is done in living individuals for estimation of chronological age, especially in the late adolescence. The aim of this study was to assess the application of Cameriere's third molar maturity index (I-3M) to determine whether an individual is 18 years or older (adult) or younger than 18 years (minor) in a sample of Dutch individuals. The sample consisted of panoramic images of 360 individuals aged between 14 and 22 years old. Three observers performed the measurements. Gender was not statistically significant in discriminating adults and minors. The highest value of the Youden index of the receiver operating curve analysis was for the value of I-3M < 0.08 in discriminating individuals as minor or adult. The specificity (Sp) and sensitivity (Se) results for females were 96.3% and 72.7% respectively. The Sp and Se for males were 95.0% and 84.0% respectively. The probabilities of correctly classified individuals were 83.3% and 88.9%, and Bayes post-test probability was 96.3% and 95.7% in females and males respectively. Obtained results showed that the specific cut-off point of I-3M < 0.08 may be a useful and reliable method for adult age assessment in a Dutch population. (c) 2017 Elsevier B.V. All rights reserved.

(2014) Tuncer, Duygu; Celik, Cigdem; Cehreli, Sevi Burcak; Arhun, Neslihan; https://orcid.org/0000-0002-5936-0196; AAA-1576-2021; AAD-6138-2021; R-2536-2019
Aim: The aim was to compare the microleakage of resin composite bonded with different adhesive systems in class-II cavities at enamel or dentine margins. Material and methods: 60 extracted human molar teeth received slot cavity preparations on mesial and distal surfaces (mesial cervical margin was prepared in enamel and distal in dentine). They were randomly divided into five groups (n=12) according to the adhesive system: Group-A: Silorane Bond (S), Group-B: Adper Single Bond 2 (SB), Group-C: Clearfil SE Bond (CSE), Group-D: Single Bond Universal (USel) (selective etch-and-rinse), Group-E: Single Bond Universal (USE) (all-in-one). The preparations were restored using the same resin composite (Filtek Ultimate) except Group A which was restored by Silorane composite. The teeth were thermocycled, immersed in dye, sectioned, and dye penetration was evaluated quantitatively using image analysis. The data were analyzed using the two-way analysis of variance and Bonferroni test. Results: In all groups, there was no statistically significant difference between enamel margins at occlusal and gingival sites (p>0.05). The statistical difference between Group-A (S) and Group-B (SB) was significant at all margins. Group-B (SB) presented the greatest microleakage amounts at all margins and the highest scores were obtained in the dentine. Likewise, SB demonstrated statistically significant differences between dentine and enamel margins (occlusal and gingival)(p<0.05). Conclusion: All adhesive systems showed similar microleakage values between enamel margins in occlusal and gingival regions. However, when the gingival margin is located in the dentine, etch&rinse adhesive systems may not be a choice in terms of microleakage prevention.

(2016) Tirali, Resmiye Ebru; Ilhan, Banu; Sar, Cagla; Cehreli, Sevi Burcak; 0000-0001-6487-3984; 0000-0003-4966-9779; 27159668; HZK-4947-2023; AAD-2907-2020; AAD-6138-2021
Toriello-Carey syndrome is a rare disease whose clinical manifestations are midline facial defects, laryngeal and pharyngeal hypoplasia, cardiac defect, and corpus callosum hypoplasia. Literature states that clinical manifestations are more evident in males. This is the second report in the literature which describes the dental and dentofacial features in an 8-year-old female patient with Toriello-Carey syndrome.
Does MIH Affects Preoperative and Intraoperative Hypersensitivity?
(2022) Ozgul, Betul Memis; Sakaryali, Didem; Tirali, Resmiye Ebru; Cehreli, Sevi Burcak; 35830629
Objective: Hypersensitivity is an important problem that is encountered during the treatment of hypomineralized teeth. The aim of this prospective study was to compare responses to electrical pulp tests (EPTs) and cold tests among carious teeth with and without molar incisor hypomineralization (MIH) before and after the administration of local anesthesia for caries removal Results: The EPT results of anesthetized carious teeth without MIH were significantly higher than those of carious teeth with MIH (p = 0.011). The cold test results were significantly higher for anesthetized carious teeth with MIH than for those without MIH (p = 0.0001). Intraoperative pain was significantly higher for carious teeth with MIH (p = 0.003). Conclusions: The results of this study suggest that even after achieving sufficient anesthesia, hypersensitivity remains a clinical problem in MIH-affected carious molars. The results presented in this study indicate that this phenomenon is not related to achieving effective local anesthesia; therefore, behavior management in such cases is of the utmost importance compared to relying on adjacent anesthetic methods.
Does Radiopacity of Restorative Materials Change with Aging?
(2017) Tuncer, Duygu; Gulsahi, Ayse; Cehreli, Sevi Burcak; Arhun, Neslihan; AAD-6138-2021; R-2536-2019
Background: Dental materials should be radiopaque enough to be identified from enamel and dentin and enable the detection of secondary caries, marginal defects. The aim was to evaluate the radiopacity of restorative materials after 6 months of aging in distilled water. Material and Methods: Twenty-two restorative materials were used and the radiopacity them were first evaluated after setting and after 6-months of storage in distilled water. Human primary and permanent tooth slices were also used in the study. Restorative material specimens were prepared by using Teflon molds. Twelve specimens were prepared for each material group. All specimens were exposed together with an aluminum stepwedge using a phosphor plate. The analysis was made with Digora system. Results: Filtek-Silorane, Aelite-LSPosterior, Theracal-LC, Biodentine, Ionofil-U, Vitrebond and GCP-Glass-Seal exhibited lower radiopacity values at the initial setting and after 6-months of aging with respect to permanent enamel. When compared with deciduous enamel, Filtek-Z550, Charisma, Riva-Light Cure and Equia-Fil exhibited lower radiopacity values at both readings. Spectrum-TPH, Filtek-Ultimate, Clearfil-Majesty Flow, Sultan-Versa, IRM and Adhesor exhibited statistically significant higher values of radiopacity at the 6-month evaluation. Conclusion: The radiopacity of restorative materials is dependent on the material type exerting different radiopacity values after 6-months.

(2016) Ozkalayci, Ozlem; Araz, Coskun; Cehreli, Sevi Burcak; Tirali, Resmiye Ebru; Kayhan, Zeynep; 0000-0002-4927-6660; 0000-0001-6487-3984; 0000-0003-0579-1115; 27687464; AAJ-4576-2021; AAD-6138-2021; HZK-4947-2023; AAD-2907-2020; AAJ-4623-2021
Study objective: The study aimed to investigate the effects of listening to music or providing sound isolation on the depth of sedation and need for sedatives in pediatric dental patients. Design: Prospective, randomized, and controlled study. Setting: Tertiary, university hospital. Patients: In total, 180 pediatric patients, American Society of Anesthesiologists physical status I and II, who were scheduled for dental procedures of tooth extraction, filling, amputation, and root treatment. Interventions: Patients were categorized into 3 groups: music, isolation, and control. During the procedures, the patients in the music group listened to Vivaldi's The Four Seasons violin concertos by sound isolating headphones, whereas the patients in the isolation group wore the headphones but did not listen to music. All patients were sedated by 0.1 mg/kg midazolam and 1 mg/kg propofol. During the procedure, an additional 0.5 mg/kg propofol was administered as required. Measurements and main results: Bispectral index was used for quantifying the depth of sedation, and total dosage of the propofol was used for sedative requirements. The patients' heart rates, oxygen saturations, and Observer's Assessment of Alertness and Sedation Scale and bispectral index scores, which were monitored during the operation, were similar among the groups. In terms of the amount of propofol used, the groups were similar. Prolonged postoperative recovery cases were found to be significantly frequent in the control group, according to the recovery duration measurements (P = .004). Conclusions: Listening to music or providing sound isolation during pediatric dental interventions did not alter the sedation level, amount of medication, and hemodynamic variables significantly. This result might be due to the deep sedation levels reached during the procedures. However, listening to music and providing sound isolation might have contributed in shortening the postoperative recovery duration of the patients. (C) 2016 Elsevier Inc. All rights reserved.
Evaluation of Antibacterial Efficiency of Different Root Canal Disinfection Techniques in Primary Teeth
(2018) Oter, Banu; Topcuoglu, Nursen; Tank, Mehmet K.; Cehreli, Sevi Burcak; 29480759; AAD-6138-2021
Background: A successful primary root canal treatment depends on effective shaping and cleaning the root canal system and finally filling it with a hermetic sealer. Clinically, roots of primary teeth are difficult to shape and the irrigation/disinfection protocol has great importance on prognosis. Objective: The present study evaluated the antibacterial efficiency of Endosafe (Orangedental GmbH & Co. KG), photo-activated disinfection (PAD; Orangedental GmbH & Co. KG), diode laser (Epic 10; Biolase, Inc.), ozone (O-3, Ozonytron; Biozonix, Munchen, Germany), and sodium hypochloride applications in primary root canals that were infected with Enterococcus faecalis after standard mechanical instrumentation. Methods: The study was conducted on roots of 100 human primary molar teeth, which were extracted due to excessive caries. The roots were divided in 5 groups with 15 roots in each root disinfection protocol. In addition, 15 samples and 10 samples served as positive and negative controls, respectively. The Shapiro-Wilk test, the Kruskal-Wallis test and then by post hoc group comparisons with the Bonferroni-adjusted Mann-Whitney U test (unpaired observations) was used. Results: Sodium hypochlorite (NaOCl) exhibited the highest antibacterial effect (0 colony-forming units per mL). Diode laser irradiation was statistically more effective than the ozone, PAD, and Endosafe groups (p<0.001). Endosafe, PAD, and ozone groups showed similar antibacterial effect (p>0.05). Although not statistically significant, the Endosafe was more effective in reducing the bacterial count when compared with ozone and PAD. Conclusions: The five tested irrigation systems were shown to be effective in disinfection of the E. faecalis-contaminated primary root canals and best results were obtained with 2.5% NaOCl and diode laser.
Evaluation of Possible Associated Factors for Early Childhood Caries and Severe Early Childhood Caries: A Multicenter Cross-Sectional Survey
(2016) Ozen, Bugra; Van Strijp, A. J. P.; Ozer, Levent; Olmus, Hulya; Genc, Aysegul; Cehreli, Sevi Burcak; 26950812; AAD-6138-2021
Objectives: The present study evaluated associated factors for developing early childhood caries (ECC) and Severe-ECC (S-ECC) in a group of children aged 24-71 months. Potential positive effects of early dental visit on formation of ECC is investigated as well. Study Design: This was a multicenter, cross-sectional study conducted at three governmental and university pediatric dentistry clinics in 408 preschool children who were randomly selected from a total of 4116 children. The questionnaires administered to the mothers by interview and intraoral examination performed by calibrated pediatric dentists. The children were evaluated in three groups according to their caries experience as who had caries free, ECC and S-ECC. Results: The following factors were significantly associated with caries formation: 1. Prolonged (i.e., >18 months) breasffeeding in preterm babies (OR=2.4) 2.Prolonged breasffeeding in children who started tooth brushing after 1.5 years of age (OR=3.7), 3. Sugar (p<0.001) and fruit-juice consumption (p<0.0001), and 4. Lack of periodic dental examination (p<0.05). Parental smoking habit does not significantly affect ECC development. Nocturnal bottle feeding and nocturnal feeding also affected S-ECC formation significantly (p=0.043 and p=0.005, respectively). Conclusions: There is a significant difference between the children with caries and caries-free associated with the brushing initiation age started before or after 18 months. If a child is under the risk of multiple caries factors, it is very difficult to evaluate which habits affect the caries formation or increase the severity of the caries lesions.
Use of Cone-Beam Computed Tomography in Diagnosis of An Otherwise Undetected Periapical Lesion in An Anomalous Tooth
(2014) Gulsahi, Ayse; Ates, Ufuk; Tirali, Resmiye Ebru; Cehreli, Sevi Burcak; https://orcid.org/0000-0001-6487-3984; HGA-3970-2022; AAD-2907-2020; AAD-6138-2021
Fusion is a developmental anomaly of dental hard tissues. Since dental fusion is characterized by irregular coronal morphology and a complex endodontic anatomy, endodontic therapy of such teeth may present a serious clinical challenge. Cone-beam computed tomography (CBCT) is a useful tool for the management of complex endodontic problems and dental anomalies. In the case presented here, a CBCT scan revealed morphological details as well as the severity of periapical infection that had not been visualized with conventional imaging techniques. The results obtained with detailed imaging led to a change in the treatment plan.
