    Correlations between fractal dimension of mandibular condylar bone and Degenerative Joint Disease - A CBCT based analysis
    (2019) Gümüşsoy, İsmail; Duman, Şuayip B.; Bayrakdar, İbrahim S.; Yasa, Yasin; Cakur, Binali
    Abstract: Aim: The aim of this study was to determine whether correlationsexisted between the fractal dimension (FD) valueof the mandibular condyle and radiographic findingsof degenerative joint disease (DJD) using cone beam CT(CBCT).Materials and Method: 100 TMJ CBCT images wereretrospectively analyzed. CBCT images of patients wereassessed with regard to erosive degenerative bone change(DBC) in the mandibular condyle. We divided eachcondyle into 3 groups and scored (0, 1, 2) according todiagnosis of DJD: with 0 indicating normal condyles ornon-demonstrable change, 1 indicating mild erosive DBCand 2 indicating severe erosive DBC. Fractal analysis (FA)was applicated to CBCT image of mandibular condyle.FD values were compared with the radiographic diagnosisscores.Results: ANOVA test showed that there was statisticallysignificant difference between the FD values of patientwith erosive DBC and patient having no erosive change.The average FD value of patient group 0 was 1.079, theaverage FD value of patient group 1 was 1.052, the averageFD value of patient group 2 was 1.036. Lower FD valuesand more severe degenerative changes were seen inpatient group 2.Conclusion: In our study, we found that as the gradeof bone degeneration increased, FD values decreased.These findings suggest a promising result in related topic.However, this paper is a preliminary study of FA andDBC. Further studies should be performed to ensure FA isclinically feasible.

    Do children with Wilson's disease have distinct craniofacial morphology? A cephalometric study
    (Elsevier Ireland Ltd, 2013) Kilic, Nihat; Sumbullu, M. Akif; Ertekin, Vildan; Catal, Gulhan; Cakur, Binali; Oktay, Husamettin; Selimoglu, Mukadder Ayse
    Objectives: Patients with Wilson's disease (WD) develop osseous changes such as osteoporosis, spontaneous fractures, areas of sclerosis and demineralization of maxillary and mandibular bones, and neurologic symptoms including swallowing dysfunctions, which may affect dento-facial growth. However, dento-maxillo-facial structures of these patients have never been investigated. The present study aimed to discover if subjects with WD have different dentofacial structures. Methods: Lateral cephalometric films of 13 children (5 males and 8 females) with WD and of 15 normal subjects (6 males and 9 females) were evaluated. Mean ages of the patients and controls were 12.62 +/- 3.09 years and 12.01 +/- 1.38 years, respectively. Lateral cephalometric cranial films of all subjects were taken in the same cephalostat in a habitual and unstrained body posture. Thirteen linear and 11 angular parameters were measured to describe the craniofacial characteristics of the subjects. Results: Statistical analysis showed that there is no statistically significant difference between parameters of normal children and children with WD, with the exception of palatal plane inclination. The inclination of palatal plane was higher in children with WD than in normal subjects. Conclusions: Children with WD and healthy children have approximately the same dento-maxillo-facial structures. However, increased palatal plane inclination may be a finding of WD.

    Nasolabial Cyst: A Case Report with Ultrasonography and Magnetic Resonance Imaging Findings
    (Hindawi Ltd, 2017) Ocak, Ali; Duman, Suayip Burak; Bayrakdar, Ibrahim Sevki; Cakur, Binali
    Nasolabial cysts are uncommon nonodontogenic lesions that occur in the nasal alar region. These lesions usually present with asymptomatic swelling but can cause pain if infected. In this case report, we describe the inadequacy of conventional radiography in a nasolabial cyst case, as well as the magnetic resonance imaging (MRI) and ultrasonography (US) findings in a 54-year-old female patient.
