Background/purpose Bruxism affects the stomatognathic system and causes tissue damage by the excessive jaw movements. The purpose of this study was to evaluate the effects of sleep bruxism on jaw bone density, mineralisation and morphology by comparing bruxers and non-bruxers. Materials and methods 60 bruxers and 60 non-bruxers (control) patients were included in the analysis. Cortical width at the gonion (GI), at the mental foramen (MI), at the antegonion (AI), the panoramic mandibular index (PMI), the mandibular cortical index (MCI) and antegonial notch depth (AND) were measured bilaterally on 120 panoramic radiographs. The measurements were evaluated for repeatability, correlation with age, gender and correlation between the variables. Results A significant association was observed between cortical shape (MCI) and bruxism status (p = 0.012). The MI was significantly different between the bruxers and non-bruxers (p = 0.006). There was a significant but weak correlation between the MI value and age in bruxers and the control (p = 0.003, p = 0.04). The AI was not associated with bruxism status and did not vary by age or gender (p > 0.05). The AND was higher in bruxers than non-bruxers (p = 0.001). Male bruxers had a significantly higher AND value than female bruxers (p = 0.001). The GI was higher in male bruxers (p = 0.001). Conclusion Defects in the endosteal margin of the cortex and cortical thickening in the mental region were detected in bruxer patients. Furthermore, AND was increased in bruxers. Tiny bone peaks accompanied the cortical thickening seen in the gonial region. Male bruxer patients had higher GI and AND values than female bruxers.

The most common indication for CBCT was malocclusion and dentomaxillofacial anomalies in the primary and permanent dentition age groups, whereas the localisation of impacted teeth was the most common indication in the mixed dentition age group. Generally, CBCT was indicated in orthodontics and surgery.

Purpose: Cone Beam Computed Tomography (CBCT) is the most current and newest imaging method in dentistry. Since low radiation dose and true 3D image acquisition, use of CBCT is becoming increasingly common. The aim of this study is to determine demographic information and indications of the patients taken CBCT Material and Method: In the current study, a total of 843 patients' CBCT (i-CAT; Imaging Sciences International, Hatfield, PA, USA). The patients were divided into subgroups according to their age, gender, and radiographic indications. The descriptive statistics was used to review the data. Result: A total of 843 patients' CBCT were examined retrospectively. Out of the 843 patients, 453 were female and 390 were male. Average age of these patients was 29,7. 1/3 of the DVT was taken form 11 ages to 20 ages patients. Out of the 843 patients, 252 had partial or total edentulous jaws, 218 had orthodontic anomalies. TMJ disorders and impacted teeth were followed up them. Conclusion:The use of the CBCT has been increased day by day. Especially in implant and impacted teeth surgery and orthodontics, it widely used. In addition, CBCT's were mostly taken from young patients.

KM is a very rare clinical condition and few treatment options described. Early detection is essential to preclude complications and to provide more successful treatment. In this study, we evaluated the cases of KM and review of the literature also presented.
