Öğe Assessment of pharyngeal airway volume in adolescent patients affected by bilateral cleft lip and palate using cone beam computed tomography(E H Angle Education Research Foundation, Inc, 2014) Celikoglu, Mevlut; Ucar, Faruk I.; Sekerci, Ahmet E.; Buyuk, Suleyman K.; Ersoz, Mustafa; Sisman, YildirayObjective: To test the null hypothesis that there were no significant differences for pharyngeal airway volumes between the adolescent patients affected by bilateral cleft lip and palate (BCLP) and well-matched controls using cone beam computed tomography. Materials and Methods: The study sample consisted of 16 patients (11 female and 5 male; mean [SD] age 14.1 [2.1] years) affected by BCLP and 16 patients (10 female and 6 male; mean [SD] age 13.4 [2.0] years) as age- and sex-matched control group. Craniofacial measurements and pharyngeal airway dimension, area, and volume measurements of patients in both groups were calculated and statistically examined using Student's t-test and multiple linear regression analyses. Results: Statistically significant differences were found between the BCLP and control groups for SNB (P <.05), SN-GoGn (P <.05), Co-A (P <.05), PAS (P <.01), minAx (P <.01), and oropharyngeal airway volume (P <.05). The most predictive variables for oropharyngeal airway volume were found as PAS (r =.655 and P =.000) and minAx (r =.787 and P =.000). Conclusions: The null hypothesis was rejected. Oropharyngeal (P <.05) and total (P>.05) airway volumes were found to be less in the BCLP group, and thus the treatment choice in these patients should have positive effects on the pharyngeal airway.Öğe Effects of force magnitude on relapse: An experimental study in rabbits(Mosby-Elsevier, 2011) Kilic, Nihat; Oktay, Husamettin; Ersoz, MustafaIntroduction: The aims of this study were to investigate the effects of 2 force levels on the amount of relapse and to determine whether there is a relationship between the rates of tooth movement and relapse. Methods: Approximately 20-g (group I) and 60-g (group II) forces were applied to the maxillary central incisors of 25 young adult (14 weeks of age) New Zealand female rabbits. Active tooth movement lasted 20 days. Then, the appliances were removed, and the incisors were released. The distance between the incisors was measured daily from the midlevels of the crowns by using a digital caliper during the active phase of tooth movement for 20 days, and then relapse was measured at the same level for 37 days. Analysis of variance and the Bonferroni multiple range test were used for statistical analyses. Results: After active tooth movement, the mean total opening amounts were 3.98 +/- 0.59 mm in group I and 4.82 +/- 0.82 mm in group II, and the mean difference was approximately 0.8 mm. A rapid relapse was observed on the initial days in both groups, and its rate decreased with time. Significant relapse was observed in the first 5 and 8 days of the experiment in 20-g and 60-g force groups, respectively. The relapse in group II was significantly greater than in group I only on the first day of experiment. Statistically significant correlations were found between total tooth movement and relapse (R=0.896, P<0.001). Conclusions: These results showed a close relationship between the amount of relapse and orthodontic force magnitude. Greater relapse occurred during the initial days after appliance removal, and this indicates that retention appliances are needed immediately after the removal of orthodontic appliances.

Methods: In this retrospective study, the samples were selected from the files of 450 patients treated at the Department of Orthodontics, Inonu University. The files of patients whose treatments were completed as planned were included in the study. In total, 387 patients (137 males and 250 females) met this criterion (mean age: 14.65 years). Patients were divided into three groups: treatment duration less than 20 months (group A), between 20-30 months (group B), and more than 30 months (group C). Analysis of variance (ANOVA) and t-tests were conducted to determine the difference in treatment duration between the groups and sexes. Results: From the 387 patients, 78 (20.2%) had Class I, 254 (65.6%) had Class II, and 55 (14.2%) had Class III malocclusion. The average treatment duration was 27.82 months (males: 31.82 months, females: 29.33 months). There were no statistically significant differences between the sexes according to the treatment duration. The average treatment duration according to malocclusions was 26.24 months for Class I, 28.22 months for Class II, and 28.21 months for Class III. The distribution of the groups according to treatment duration was as follows: Group A: 72 (18.6%), Group B: 173 (44.7%), and Group C: 142 (36.7%) patients. The relationship between the treatment durations and Angle classifications was not statistically significant (p=0.216). Conclusion: This study showed that there were severe anomalies and problematic malformations within each Angle classification because no statistically significant difference among the malocclusion classes in terms of the duration of treatment was found. Therefore, besides the anomaly type, the treatment duration and effort put into the work should also be taken into consideration in determining the treatment charge.Öğe Facial soft-tissue thickness in patients affected by bilateral cleft lip and palate: A retrospective cone-beam computed tomography study(Mosby-Elsevier, 2014) Celikoglu, Mevlut; Buyuk, Suleyman K.; Sekerci, Ahmet E.; Ersoz, Mustafa; Celik, Salih; Sisman, YildirayIntroduction: The purposes of this study were to evaluate the facial soft-tissue thicknesses and craniofacial morphologies of patients affected by bilateral cleft lip and palate (BCLP) and to compare the findings with a well-matched control group without any clefts using cone-beam computed tomography. Methods: The study sample consisted of 40 retrospectively and randomly selected patients divided into 2 groups: a BCLP group (20 patients; mean age, 13.78 +/- 3.20 years) and an age-and sex-matched control group without clefts (20 patients; mean age, 13.94 +/- 2.52 years). Craniofacial and facial soft-tissue thickness measurements were made with cone-beam computed tomography. The Student t test and multiple linear regression analyses were performed for the statistical evaluations. Results: The BCLP group had an increased SN-MP angle (P = 0.003), a decreased Co-A (P = 0.000), and retruded maxillary (P = 0.000) and mandibular (P = 0.026) incisors. In addition, patients affected by BCLP had statistically significantly decreased thickness measurements for the variables subnasale (P = 0.005) and labrale superior (P = 0.026) compared with the controls. The most predictive variables were found at U1-SN (r = 0.417, P = 0.004), IMPA (r = 0.368, P = 0.010), and ANB (r = -0.297, P = 0.031) for subnasale and U1-SN (r = 0.284, P = 0.038) for labrale superior. Conclusions: The BCLP group showed greater vertical growth, greater retrusion of the maxilla and the maxillary and mandibular incisors, and decreased subnasale and labrale superior thicknesses compared with the well-matched controls without clefts. These differences should be taken into account when planning orthodontic and orthognathic surgery treatment for those patients.Öğe Micro-CT evaluation of microleakage under orthodontic ceramic brackets bonded with different bonding techniques and adhesives(Oxford Univ Press, 2016) Ozturk, Firat; Ersoz, Mustafa; Ozturk, Seyit Ahmet; Hatunoglu, Erdem; Malkoc, SiddikThe aim of this study was to evaluate microleakage under orthodontic ceramic brackets bonded with direct and different indirect bonding techniques and adhesives using micro-computed tomography. A total of 30 human maxillary premolars were randomly separated into five groups with six teeth in each group. In group I, teeth were bonded directly with Transbond XT (3M Unitek). In group II, group III, group IV, and group V, teeth were bonded through an indirect technique with Custom I.Q. (Reliance Orthodontic Products), Sondhi Rapid-Set (3M Unitek), RMbond (RMO), and Transbond IDB (3M Unitek), respectively, following the manufacturer's instructions. Micro-CT system model 1172 of Skyscan (Kontich, Belgium) was used to scan all samples. NRecon (Skyscan) version 1.6, CT-Analyser V.1.11 (Skyscan), and TView (SkyScan, Bvba) software programs were used for microleakage evaluation. Microleakage values between the test groups were assessed using the Kruskal-Wallis test, while the Wilcoxon signed rank test was used for within-group comparisons. The level of significance was set at P < 0.05. According to the Kruskal-Wallis analysis of variance test, there were no significant differences among the tested groups, with regard to volume and percentage (microleakage/region of interest x 100) of microleakage values (P < 0.05). The Wilcoxon signed rank test showed that coronal microleakage volume and percentage values significantly differed for RMbond and Transbond IDB groups. In the study, only ceramic brackets were used and microleakage into mini gaps did not show up on the micro-CT image because 50% silver nitrate solution could not penetrate into mini gaps which are smaller than silver nitrate particles. Use of direct and indirect bonding techniques with different adhesives did not significantly affect the amount of microleakage.Öğe The Orthodontic Treatment of a Patient with Idiopathic Root Resorption in Upper Incisors(Aves Press Ltd, 2015) Celik, Ozge; Ersoz, Mustafa; Kamalak, HakanThe aim of this case report was to present the treatment of a 14-year-old patient with anterior crossbite with idiopathic root resorption. A 14-year-old female patient referred to our clinic because of the presence of crossbite on the maxillary central incisor. The smile esthetics were compromised because of the crossbite of the maxillary right central incisor. Intraorally, the patient had an Angle Class I molar relationship on the left side, and her lower right first molar was lost because of decay. Initial cephalometric analysis showed that the ANB angle was -1.3, and the upper and lower incisor angles were105.9 and 82.3, respectively. The arch length discrepancies in the upper and lower arches were -2.9 mm and 4 mm, respectively. On radiographical examination, we noticed severe root resorptions. Hormonal tests (FT3, FT4, and TSH) were performed. The parents of the patient were informed about the root resorption. In the hematological and biochemical examinations, the patient did not show any problems. As a result of 8-month treatment, the chief complaint of crossbite was corrected in five months. The teeth were leveled and aligned. The final occlusion showed a Class I canine and molar relationship. Posttreatment radiographs showed that the pretreatment maxillary incisors' root resorption was at the same level. A satisfying occlusion and esthetic were achieved. Orthodontic treatment of the teeth with idiopathic root resorption can be achieved using proper mechanics and optimum force.Öğe A Patient- and Family-Centered Care Approach to Orthodontics: Assessment of Feedbacks from Orthodontic Patients and Their Families(Aves Press Ltd, 2016) Ersoz, Mustafa; Uz, Zehra; Malkoc, Siddik; Karatas, MehmetObjective: This study aimed to evaluate orthodontic patients and their families' clinical satisfaction and their perception of dentists in the framework of the Patient and Family Centered Care (PFCC) concept. Methods: The study population comprised patients treated at the Orthodontics clinic and their families. A mixed method research with quantitative and qualitative components was employed by conducting questionnaires with 62 patients and 65 parents. Collected data were recorded on the computer, and analyses were performed. Results: A majority of the patients who received treatment at our clinic were high school graduates, while their parents were university graduates. The patient's and their parents' overall satisfaction were similar. We also found that the patients and their parents expected doctors to have ethical perception and professional behavior in the treatment process. Conclusion: According to the results obtained from the survey questionnaires, the patients and their parents expect a dentist to have the following qualities: courtesy, friendliness, respect, punctuality, communication skills, and knowledgeableness. Dentists can optimize clinical and patient satisfaction by providing care and attention based on the principles of patient centered care (PCC) and PFCC and shaped in accordance with the expectations of the patients and their parents.Öğe Real-time cell analysis of the cytotoxicity of the components of orthodontic acrylic materials on gingival fibroblasts(Mosby-Elsevier, 2011) Ozturk, Firat; Malkoc, Siddik; Ersoz, Mustafa; Hakki, Sema S.; Bozkurt, Buket S.Introduction: The aim of this study was to evaluate the cytotoxicity of 3 orthodontic acrylic materials and 2 manipulation methods. Methods: The orthodontic acrylic materials Orthocryl EQ (Dentaurum, Ispringen, Germany), Orthoplast (Vertex Dental, Zeist, The Netherlands), and O-80 (Imicryl, Konya, Turkey) were prepared with 2 polymerization methods (doughing and spray on). Totally, 60 cylinders (5 x 2 mm), fabricated by using a different acrylic and method, were divided into 6 groups. Gingival fibroblasts were isolated from gingival connective tissue of systemically healthy subjects. Materials were incubated in Dulbecco's modified eagle's medium culture medium (Biological Industries, Beit Haemek, Israel) for 72 hours according to ISO 10993-5 standards (surface area to volume ratio of the specimen to cell-culture medium: 3 cm(2)/mL). Gingival fibroblasts were maintained with Dulbecco's modified eagle medium containing 10% fetal bovine serum. A real-time cell analyzer (RT-CES, xCELLigence; Roche Applied Science, Mannheim, Germany, and ACEA Biosciences, San Diego, Calif) was used to evaluate cell survival. After seeding 200 mu L of the cell suspensions into the wells (20,000 cells/well) of the E-plate 96, gingival fibroblasts were treated with bioactive components released by the acrylic materials (1/1 and 1/2 dilutions) and monitored every 15 minutes for 121 hours. For the proliferation experiments, the statistical analyses used were 1-way analysis of variance (ANOVA) and Tukey-Kramer multiple comparisons tests. Results: There was no significant difference between the cell indexes of the control and study groups for the 1/1 and 1/2 dilutions at 21 and 32 hours. When evaluated at 68 hours, all 1/2 dilutions of acrylic materials showed statistically insignificant differences (P >0.05) except for Orthoplast (P <0.05). But all acrylic materials were different from the control group in the 1/1 dilutions (P <0.001). At 121 hours, all test groups were significantly different from the untreated control group (P <0.001). Conclusions: The results indicate that the long cycle increased the cytotoxicity of the tested materials, and there was no significant difference between the spray-on and doughing methods on cytotoxicity.
