Öğe Antimicrobial effects of several calcium silicate-based root-end filling materials(Japanese Soc Dental Materials Devices, 2014) Damlar, Ibrahim; Ozcan, Erhan; Yula, Erkan; Yalcin, Muhammet; Celik, SalihThe purpose of this study was to evaluate, in vitro, the antimicrobial effect of iRoot BP, iRoot BP Plus, and mineral trioxide aggregate (MTA) against Entercoccus faecalis and Candida albicans by using direct contact test. The materials were tested immediately after application to the microtiter wells and after setting for 1-day and for 7-days. Ten microliters of microbial suspension was added to each well for direct contact with each material for 1 h at 37 degrees C and 100% humidity. Then fresh media was added and, survival of bacteria and fungi was determined by using 10-fold serial dilution and inoculated onto agar plates. In fresh and 1-day samples all of tested materials showed statistically significant antimicrobial effects compared to control groups (p<0.05). In 7-day samples, there were no significantly differences compared to control groups. MTA, iRoot BP and iRoot BP Plus had similar antimicrobial efficacy against E. faecalis and C. albicans.Öğe Applicability of the Demirjian method for dental assessment of southern Turkish children(Elsevier Sci Ltd, 2014) Celik, Salih; Zeren, Cem; Celikel, Adnan; Yengil, Erhan; Altan, AhmetAge-related legal problems are especially common in underdeveloped parts of Turkey. In terms of civil and criminal law, the ages from 13 years to 18 years are critical in our country. Estimation of age is a very significant in aspect of accordance with laws. The aims of this study were to evaluate the applicability and accuracy of the Demirjian technique for assessing southern Turkish children; to analyze the sexual dimorphism of dental age in the studied groups; and to define the relationship between the dental age and the degree of mineralization in mandibular permanent tooth in southern Turkish children. This study was performed using panoramic radiographs from 932 healthy southern Turkish children, 444 girls and 488 boys aged between 4 and 18 years. Statistical evaluations were performed using SPSS (Statistical Package for Social Sciences) for Windows 13.0 software. The mean difference between dental and chronological age was calculated for each age and sex group. The paired t-test was used to compare all data. The chi-square test was used for between-group comparisons of categorical variables. Continuous variables were tested for normality using the Kolmogorov-Smirnov test. Relationships between continuous variables were examined using Pearson's correlation coefficient. The same observer re-examined 700 teeth three months after the first examination. The results were evaluated with the intraclass correlation test and both measurements were statistically significantly similar with each other(R = 0.982, p = 0.0001). Dental age (DA) and chronological age (CA) were consistent for boys in the 16-16.9 age group and for girls in the 9-9.9 and 15-15.9 age groups. From this study, we can conclude that dental age varies across ethnic populations. Additionally, dental maturation varies across different regions of the same country. Because Demirjian's standards are not suitable for all age groups of southern Turkish children, a new table is necessary for evaluating this population. Future studies using multi-ethnic population data are needed to establish the international applicability of Demirjian's method. (C) 2014 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

However, no study, dealing with EtG analysis in dental tissue, was performed so far. In this study, we aimed to demonstrate EtG levels in dental tissue. Materials and methods: Michigan Alcohol Screening Test (MAST) was performed to 29 participants. Following the test, cases were divided into three groups as non-hazardous alcohol users, alcohol abusers and 6 controls who verbally declared that they were abstainers. A total of 29 tooth specimens, obtained from participants, Was included in the study. These specimens were analyzed using LC/MS/MS. Results: All of the participants included in the study were male. According to the MAST outcomes 14 of the participants were non-hazardous alcohol users, and 9 were alcohol abusers, while 6 patients verbally declared that they were abstainers. Dental tissue analyses revealed EtG levels ranging between EtG < LOD and 23.39 pg/mg. EtG levels were observed to beÖğe THE EFFECTS OF ERDOSTEINE ON COAGULATION IN RATS(Carbone Editore, 2014) Motor, Sedat; Alp, Harun; Yuksel, Rana; Erden, Ersin Sukru; Oktar, Suleyman; Celik, Salih; Cayirci, GokhanBackground and objectives: Erdosteine, a thiol derivative in the same group as N-acetyl cysteine, belongs to a class of medicines called expectorants. Aim: It was aimed to determine effects of erdosteine (ERD) on coagulation. Material and methods: A total of 23 female rats were divided into three groups as control (C) (n=7), ERD-10 (n=7), ERD-50 (n=9). Rats in C group were given dilution of 0.3 ml sodium bicarbonate [NaHCO3]; rats in ERD-10 group were given 10 mg/kg ERD; and rats in ERD-50 group were given 50 mg/kg ERD. The drugs were given for ten days by oral gavage. Blood samples were drawn from the heart 24 hours after the last drug dose, and coagulation parameters were measured with automated analyzers. Results: While Factor VIII and AT-III levels decreased in both ERD-10 and ERD-50 group, Factor IX levels only decreased in ERD-50 group. Also, INR, PT and aPTT were prolonged in the ERD-50 group compared with the control and ERD-10 groups. There was no significant difference between groups for protein C and S. Conclusion: The results showed that erdosteine may increase bleeding tendencies in a dose-related manner. Therefore, we suggest that it should be noted when erdosteine is used together with anticoagulant medications. In addition, patients should be questioned regarding the use of erdosteine before dental or medical operations in order to prevent bleeding abnormalities.Öğe The effects of erdosteine on coagulation in rats(Acta Medica Mediterranea, 2014) Motor, Sedat; Alp, Harun; Yuksel, Rana; Erden, Ersin Sukru; Oktar, Suleyman; Celik, Salih; Cayirci, GokhanBackground and objectives: Erdosteine, a thiol derivative in the same group as N-acetyl cysteine, belongs to a class of medicines called expectorants.

The procedure set out below satisfies a wide-access approach for the prevention of facial nerve injury. Materials and Methods: The preauricular approach with the additional deep subfascial approach was applied to 18 patients who had various problems from ankylosis to internal derangement. All patients were assessed at the following postoperative times. Facial nerve functions were evaluated after surgery and 24 hours after surgery by the House-Brackmann facial nerve grading system. Results: Temporary facial nerve palsy was seen in a patient who had a residual keratocyst in the condylar neck region. Other patients tolerated the procedure well, and there were no other complications. Discussion: This procedure significantly decreased the risk of facial nerve injury. However, soft tissue traction at the condylar neck region or zygomatic arch where the facial nerve passes close by may increase the risk of nerve damage.Öğe Evaluation of Discectomy and Dermis-Fat Grafting on the Contralateral Side(Lippincott Williams & Wilkins, 2012) Candirli, Celal; Esen, Alparslan; Taskesen, Fatih; Celik, Salih; Cakir, BanuPurpose: We investigated the effects of unilateral discectomy with an abdominal dermis-fat graft of the temporomandibular joint (TMJ) on the contralateral side. Patients and Methods: A total of 14 patients who underwent unilateral TMJ discectomy and dermis-fat grafting for severe internal derangement in 2009 and 2010 were included. Clinical parameters, such as maximum mouth opening and lateral movements of the mandible, were recorded preoperatively and at 1 year postoperatively. Preoperative and 1-year postoperative magnetic resonance imaging was conducted to determine the duration of the operated and unoperated TMJs. Results and Conclusions: All 14 patients showed improvement in the mandibular mobility and function. However, postsurgical disc displacement without reduction was observed on the unoperated TMJ in 1 patient. Another patient complained of crepitus on the operated TMJ. Primary occlusal contact on the operated side of occlusion was observed in 2 other patients. Maximum mouth opening and measured lateral movements had increased in all patients at 1 year after the operation.Öğe An evaluation of factors associated with persistent primary teeth(Oxford Univ Press, 2012) Aktan, Ali Murat; Kara, Isa; Sener, Ismail; Bereket, Cihan; Celik, Salih; Kirtay, Mustafa; Ciftci, Mehmet ErtugrulThe aim of the present study was to investigate the reasons for the persistence of primary teeth and also use panoramic radiography to determine the characteristics of persistence teeth. Four-hundred and twenty-six panoramic radiographies, which diagnosed one or more retained primary teeth, were selected from 100,577 panoramic radiographic image files from nine clinics and six different cities in Turkey. The selected radiographies were evaluated to determine the reasons for the persistence of primary teeth; furthermore, this study analyzed the characteristics of the retained primary teeth including tooth type, number, location, and root resorption, and whether, or not, the primary teeth showed evidence of pathological conditions, such as periodontal problems, caries, ankylosis, infra-occlusions, or tipping of the adjacent permanent teeth. Six hundred and seventy-seven retained primary teeth were determined in 426 patients (148 males and 278 females). Retained primary teeth were found most frequently in the mandible rather than the maxilla and the left side was more frequently affected than the right side. Level 1 was found as a most frequently encountered root resorption level. Within the limitation of the present study, the most common type of persistent primary teeth seen on the dental arch were mandibular primary second molars, followed by maxillary primary canines. The most frequent reason for the persistence was the congenital absence of successors to the primary teeth, followed by impaction of the successor teeth.Öğe Periodontal Manifestation in a Patient with Kindler Syndrome(Hindawi Ltd, 2021) Sari, Aysegul; Celik, SalihKindler syndrome is a rare subtype of inherited epidermolysis bullosa. A 42-year-old female patient was admitted to our clinic with a complaint of tooth mobility. Multiple hypo- and hyperpigmented macules dissipated all over her body, prominent poikilodermatous changes, xerosis of the skin, and atrophy were seen in the clinical extraoral examination. Intraoral examination showed atrophy of the buccal mucosa, limited oral opening, epidermal tissue easily separated from the connective tissue, painful ulcers of the hard palate, severe periodontitis, and keratosis of the lips. All of the teeth showed mobility. After dermatologist consultation, the diagnosis of the patient was clinically identified as Kindler syndrome. All of her teeth were extracted due to her progressive periodontal disease and late admission to our clinic. Periodontal treatment might be effective in treating and controlling oral symptoms related to the syndrome and in improving the patient's quality of life.Öğe The use of stereophotogrammetry in oral surgery: Measurement of area changes after secondary epithelization and grafting vestibuloplasties(2012) Ozturk, Adnan; Dolanmaz, Dogan; Celik, Salih; Isik, Kubilay; Karabork, Hakan; Yildiz, Ferruh; Yakar, MuratObjective: Stereophotogrammetry (SPT) is a method in which three-dimensional coordinates are calculated from multiple two-dimensional projections. The purpose of this study was to compare the surface area changes between the secondary healing and grafting vestibuloplasty techniques in the mandible by using a stereophotogrammetric technique (SPT). Patients and Methods: Thirteen patients were included in this study: six patients were managed by using full-thickness skin or palatal mucosa grafts (two full-thickness palatal mucosal grafts and four full-thickness skin grafts); the remaining seven patients, who did not accept a second surgery for graft harvesting, underwent secondary epithelization vestibuloplasties. Postoperative changes of surgical areas were measured by using SPT. Statistical Analyses: The Wilcoxon (intragroup comparisons) and Mann-Whitney U (intergroup comparisons) tests were used for analysis of data. Results: In the grafting vestibuloplasty group, the surface area gain was statistically significant (P < 0.05). In the secondary epithelization vestibuloplasty group, there was no significant difference (P > 0.05), with even decrease of surface area being noted in some cases. Conclusion: SPT is a valid method for measurement of intraoral soft tissue changes.
