    Abstract: Background We aimed to investigate the risk factors of post-coronary artery bypass grafting (CABG) atrial fibrillation (AF) in male and female patients without any history of AF, to identify the sex-specific risk factors, and to examine the effect of sex-specific risk factors on the overall population. Methods This retrospective study was conducted using the hospital database with 4,758 patients who underwent CABG surgery. Among them, 2,836 patients with complete data participated in this study. The female patients were divided into two groups as patients who developed new-onset AF after CABG and those who did not. The relationship between the patients' variables and risk factors of post-CABG AF was examined. Results The overall incidence of post CABG AF was 12.9% (386/2,836). Sex-specific incidence of AF was similar: 3.2% (91/690) and 12.9% (277/2146) in female and male patients, respectively (p = 0.849). Multiple analysis revealed the independent risk factors for male and female patients, respectively: mean age (odds ratio [OR] = 1.057, OR = 1,076), age over 65 years (OR = 2.156, OR = 2.736), the European System For Cardiac Operative Risk Evaluation Scores (EuroSCORE) (OR = 1.13, OR = 1.218), COPD (OR = 1.589, OR = 1.789), BUN level (OR = 1.026, OR = 1.019), mean cardiopulmonary bypass (CPB) time (OR = 1.007, OR = 1.010), prolonged CPB time (OR = 1.604, OR = 2.309), mean cross-clamp time (OR = 1.009, OR = 1.017), need of inotropic support (OR = 2.249, OR = 2.731), and mean mechanical ventilation time (VT) (OR = 1.026, OR = 1.027). Low left ventricular ejection fraction (LVEF) (OR = 1.419), left ventricular (LV) aneurysm repair (OR = 1.533), carotid artery disease (OR = 1.750), prolonged VT (OR = 1.729), and use of intra-aortic balloon pump (IABP) (OR = 2.436) were found to be the risk factors only for male AF patients. Unstable angina (OR = 1.969), right coronary artery (RCA) disease (OR = 2), prolonged cross-clamp time (OR = 2.152), and the number of grafts per operation (OR = 1.298) were found to be the risk factors only for female AF patients. Conclusion This study suggests that predictors of AF in the overall population may be due to isolated patient groups. Multiple regression analysis and artificial intelligence modelling should be performed on large-scale, isolated groups to make strong AF prediction.

    Abstract: Objective: The aim of this retrospective study was to determine the root and canal morphology of the mandibular first and second permanent molars in a Turkish population using cone-beam computed tomography (CBCT). Materials and Methods: CBCT images of mandibular first (n = 966) and second molar (n = 1165) teeth from 850 Turkish patients were evaluated. The root canal configurations were classified according to the method of Vertucci. The data were analyzed by Pearson's Chi-square test. Results: The majority of mandibular molars were two rooted with three canals; however, three roots were identified in 0.05% of the first molars and 0.01% of the second molars, and 100% of the additional root canals were of type I configuration. Mesial roots had more complex canal systems with more than one canal, whereas most distal roots had a type I configuration. Conclusions: Within the limitations of this study, it can be concluded that CBCT scanning provides supplemental information about the root canal configurations of mandibular molars in a Turkish population. This study may help clinicians in the root canal treatment of mandibular molars.

    In: European Journal of Dentistry, Georg Thieme Verlag KG, Vol. 03, No. 04 ( 2009-10), p. 273-279
    Abstract: Objectives: To assess the incidence of postoperative pain after single- and multi-visit endodontic treatment of teeth with vital and non-vital pulp. Methods: In total, 306 patients with teeth requiring endodontic treatment were identified and were included in this study. Two experienced clinicians treated the patients, who were randomly assigned to two groups. While the teeth of patients in group 1 were obturated, group 2 were temporarily sealed and obturated after one week. Three days after the root canal instrumentation of each tooth, the patients were asked whether they experienced any postoperative pain and to rate the level of discomfort as no, mild, moderate, or severe pain. Data were analyzed statistically using the chisquare test. Results: No significant difference in postoperative pain was found between vital and non-vital teeth (P 〉 .01). Mild, moderate, and severe pain occurred in 31.4, 13.7, and 4.6% of vital teeth, respectively. Postoperative pain occurred in 107 (69.9%) and 106 (69.3%) teeth in the single- and multi-visit treatment groups, respectively. There was no significant difference in postoperative pain between the two groups (P 〉 .01). Conclusions: The prevalence of postoperative pain did not differ between vital and non-vital teeth. The majority of patients in either groups reported no or only mild pain. (Eur J Dent 2009;3:273-279)

    Abstract: Objective: The aim of this study was to determine the root and canal morphology of the maxillary and mandibular anterior teeth in a Turkish population by analyzing cone-beam computed tomography (CBCT) images. Materials and Methods: CBCT images of 417 females and 410 males with a mean age of ranging from 14 to 70 years were examined in this study. A total of 1453 maxillary central incisors, 1504 maxillary lateral incisors, 1523 maxillary canines, 1582 mandibular central incisors, 1603 mandibular lateral incisors, and 1604 mandibular canines were analyzed. The number of root canals and the canal configurations were investigated and then were classified according to Vertucci's classification. The data were analyzed with the Pearson Chi-square test. Results: The Type 1 canal configuration was most prevalent in the maxillary anterior teeth (96.8-99.7%). The Types 2, 3, 4, and 5 canal configurations were observed within the range of 0-1.3%, 0-0.8%, 0-0.7%, and 0-1.8%, respectively. In the mandibular anterior teeth, the Type 1 canal configuration was most prevalent (77-95%). The Types 2, 3, 4, and 5 canal configurations were observed within a range of 0.2-2.7%, 0.2-1.6%, 0.9-5.9%, and 1.8-14.4%, respectively. The prevalence of two canals was higher in males than in females both in the maxillary and mandibular anterior teeth (P 〈 0.05). Conclusions: Type 1 was the most prevalent canal configuration of maxillary and mandibular anterior teeth in the Turkish population. Type 5 was the most frequently observed canal configuration of the two canalled teeth. The incidence of root canal numbers and configurations differed with sex.

    In: European Journal of Dentistry, Georg Thieme Verlag KG, Vol. 10, No. 01 ( 2016-01), p. 040-045
    Abstract: Objectives: Bulk-fill composite materials are being developed for preparation depths of up to 4 mm in an effort to simplify and improve the placement of direct composite posterior restorations. The aim of our study was to compare shear-bond strength of bulk-fill and conventional posterior composite resins. Materials and Methods: In this study, 60 caries free extracted human molars were used and sectioned parallel to occlusal surface to expose midcoronal dentin. The specimens were randomly divided into four groups. Total-etch dentine bonding system (Adper Scotchbond 1XT, 3M ESPE) was applied to dentin surface in all the groups to reduce variability in results. Then, dentine surfaces covered by following materials. Group I: SonicFill Bulk-Fill, Group II: Tetric EvoCeram (TBF), Group III: Herculite XRV Ultra, and Group IV: TBF Bulk-Fill, 2 mm × 3 mm cylindrical restorations were prepared by using application apparatus. Shear bond testing was measured by using a universal testing machine. Kruskal–Wallis and Mann–Whitney U-tests were performed to evaluate the data. Results: The highest value was observed in Group III (14.42 ± 4.34) and the lowest value was observed in Group IV (11.16 ± 2.76) and there is a statistically significant difference between these groups (P = 0.046). However, there is no statistically significant difference between the values of other groups. In this study, Group III was showed higher strength values. Conclusion: There is a need for future studies about long-term bond strength and clinical success of these adhesive and bulk-fill systems.

    Abstract: Background: The aim of this study was to determine the prevalence of talon cusps in a Turkish dental patient population with respect to sexes, jaws, and dental localization to determine the relation between sex and this anomaly. Materials and Methods: A cross-sectional study was carried out. Patients attending outpatient department of Restorative Dentistry Dental School, Kirikkale between October 2009 to January 2012 were screened specifically for the presence of talon cusp during routine outpatient screening. Each patient was examined clinically and radiographically for the presence of talon cusps. Results: A total 2597 sample was evaluated. Talon cusps were observed in 31 patients. Thus, the person prevalence of talon cusp was 1.2% in this study. Gender-wise prevalence was 1.25% and 1.13% in females and males, respectively. Talon cusps were detected in 44 teeth out of a total of 35424 teeth to give a tooth prevalence of 0.12%. Maxillary lateral incisors were most commonly affected teeth in the mouth, and most commonly seen type of talon cusp was type I (23 teeth, 52.3%). Conclusion: The prevalence of talon cusps was found to be 1.2% for the Turkish dental patient population. Clinicians should be aware of potential complications that may occur with talon cusps.
