Öğe Effects of cleft lip and palate on the development of permanent upper central incisors: a cone-beam computed tomography study(Oxford Univ Press, 2015) Celebi, Ahmet A.; Ucar, Faruk I.; Sekerci, Ahmet E.; Caglaroglu, Murat; Tan, EnesObjective: The aim of this study was to evaluate 1. the differences among the cleft sides of unilateral cleft lip and palate (UCLP) patients, non-cleft sides of the same UCLP patients and well matched control patients in the root development and position of permanent upper central incisors and 2. possible gender differences. Materials and methods: The study sample consisted of 40 patient (20 males and 20 females; mean age: 14.84 +/- 3.2 years) with non-syndromic UCLP patients, and 40 control patients (20 males and 20 females; mean age: 13.38 +/- 1.6 years). Cone-beam computed tomography (CBCT) images were taken off from all patients. All tomographs were obtained in supine position by using CBCT (NewTom 5G, QR, Verona, Italy). Results: Significant smaller root volume of central incisor was observed on the cleft side than on the non-cleft side of UCLP patients (P < 0.05). No significant difference in the root development and position of the central incisors was found between the non-cleft side of the UCLP and the control group (P > 0.05). There were no statistically significant gender differences in any linear, angular, or volumetric measurements (P > 0.05). Only the root volume of the cleft side was smaller in females than in males (P < 0.05). Conclusions: In general, root volumes of central incisors on the cleft side were 12.15 per cent smaller than non-cleft side. Root development of the central incisor was much more influenced by the cleft in females than in males.Öğe Effects of early bilateral mandibular first molar extraction on condylar and ramal vertical asymmetry(Springer Heidelberg, 2013) Halicioglu, Koray; Celikoglu, Mevlut; Caglaroglu, Murat; Buyuk, Suleyman Kutalmis; Akkas, Ismail; Sekerci, Ahmet ErcanThis study aims to investigate the mandibular vertical asymmetry in a group of adult patients who had early bilateral mandibular first molar extractions. Mandibular asymmetry index measurements (condylar, ramal, and condylar plus ramal) were made on the panoramic radiographs of a study group including 30 subjects (mean age, 18.22 +/- 1.30 years) and a control group of 25 subjects (mean age, 18.24 +/- 1.17 years). Group I comprised the control group patients with no extractions and had excellent class I relationships, no missing teeth, and slight or moderate anterior crowding. Group II included patients with a bilateral mandibular first molar teeth extracted before the age of 12 years. Student's t test was used for the comparison of asymmetry index values between the groups. A paired t test was used to determine possible statistically significant differences between the sides for condylar, ramal, and condylar plus ramal height measurements. No group showed statistically significant side-specific differences for posterior vertical height measurements. Condylar asymmetry index (CAI), ramal asymmetry index, and condylar plus ramal asymmetry index measurements were not statistically different between the groups (p > 0.05). CAI values were significantly high when compared with the 3 % threshold value in the both groups, but comparisons between the groups were not statistically significant. This article investigates the effects of early bilateral mandibular molar teeth extraction that has never been investigated in the literature. The present study showed that the lengths of the condylar, ramal, and condylar plus ramal height were less in the study group than in a well-matched control group of without extraction.Öğe Evaluation of surgical-orthodontic treatments on impacted mandibular canines(Medicina Oral S L, 2011) Aras, Mutan-Hamdi; Halicioglu, Koray; Yavuz, Muhammed-Selim; Caglaroglu, MuratObjective: The aim of the study was to evaluate patients treated for impacted mandibular canines through a combined surgical and orthodontic approach. Study Design: The cases which were made button operations of impacted mandibular canines were selected from 5100 panoramic radiographs taken from patients who made use of our oral and maxillofacial surgery services between January 1998 to April 2006. All of these selected patients were assessed radiographically. Pertinent information such as sex, age at the time of surgery, site of the unerupted tooth, space availability and any other associated pathoses were also recorded. These patients were called again, and the condition of the mandibular canines was evaluated with panoramic radiographs. If the tooth erupted in the right position and it was functional and asymptomatic, we assumed the treatment to be successful clinically. Results: In the present study, from 5100 patients, 69 patients had impacted mandibular canines and only 21 patients' teeth (a total of 23 teeth) were treated orthodontically. Sixteen impacted mandibular canine teeth of 14 patients erupted successfully. Two impacted canine were extracted, and only one canine tooth was transplanted to the normal position. Four patients ended the treatment because of failure of eruption. Conclusion: If a mandibular canine tooth is impacted, not only is surgical exposure sufficient but also traction force must be applied orthodontically after the surgical exposure. In addition, age influences the success of the treatment on impacted mandibular canine teeth more than the position and impaction level of the teeth.Öğe Histopathologic investigation of the effects of prostaglandin E2 administered by different methods on tooth movement and bone metabolism(Korean Assoc Orthodontists, 2012) Caglaroglu, Murat; Erdem, AbdulvahitObjective: The aim of this study was to investigate and compare the in vivo effects of prostaglandin E2 (PGE2) administered by different methods on orthodontic tooth movement and bone metabolism macroscopically, histopatologically, and biochemically. Methods: Forty-five young adult New Zealand rabbits were randomly divided into 3 experimental groups (n = 10/group), 1 positive control group (n = 10), and 1 negative control group (n = 5). The experimental rabbits were fitted with springs exerting 20-g reciprocal force on the maxillary incisors and PGE2 (10 mu g/mL) was administered by the intravenous, submucosal, or intraligamentous route after appliance insertion and on days 1, 3, 7, and 14 thereafter. All rabbits were sacrificed on day 21 and their premaxillae were resected for histologic evaluation. Results: Tooth movement was observed in the experimental and positive control groups, but the intraligamentous PGE2 group had the highest values of all analyzed parameters, including serum calcium and phosphorus levels and osteoclastic and osteoblastic populations (p < 0.001). Conclusions: Submucosal and intraligamentous PGE2 administration significantly increases orthodontic tooth movement and bone metabolism, but the intraligamentous route seems to be more effective.
