Aim: The aim of the present cross-sectional study was to investigate the effects of bisphosphonates (BP), prescribed for osteoporosis, on jawbones using multidetector computed tomography (MDCT).
Methods: Fifty-three women who had dual-energy X-ray absorptiometry examination were scanned by MDCT. Both the cortical and the trabecular parts of the alveolar and the cortical bones were compared between BP users and non-BP users using a number of radiological measurements.
Objective: To assess the trabecular bone structure of jawbones and the dens (the odontoid process of the second cervical vertebra) amongst osteoporotic and nonosteoporotic women using cone-beam computed tomography (CBCT). Analysis of the dens trabecular bone structure aimed to test the validity of CBCT in such analysis.
Methods: Thirty-eight women who went under dual-energy X-ray absorptiometry (DXA) examination were scanned by CBCT.
Purpose: The goal of this study was to develop a new index as an objective reference for evaluating current and newly developed indices used for osteoporosis screening based on dental images. Its name; IDIOS, stands for Index of Dental-imaging Indices of Osteoporosis Screening.
Materials And Methods: A comprehensive PubMed search was conducted to retrieve studies on dental imaging-based indices for osteoporosis screening.

Purpose: This study aimed to evaluate the use of dental cone-beam computed tomography (CBCT) in the diagnosis of osteoporosis among menopausal and postmenopausal women by using only a CBCT viewer program.
Materials And Methods: Thirty-eight menopausal and postmenopausal women who underwent dual-energy X-ray absorptiometry (DXA) examination for hip and lumbar vertebrae were scanned using CBCT (field of view: 13 cm×15 cm; voxel size: 0.25 mm).
Background: Periodontal debridement has an impact on the vascular thrombotic markers in healthy individuals. This study aimed to investigate changes in several vascular thrombotic markers after surgical and non-surgical periodontal debridement in hypertensives with periodontitis.
Materials And Methods: 40 hypertensives, 27 males and 13 females, 37-68 year old, mean 51.
Objective. To determine whether differences exist between periodontitis subjects with and without Coronary Heart Disease (CHD) in a Syrian population in the distribution of IL-1 alleles at positions IL-1α+4845, IL-1β+3954, IL-1β-511, and IL-1RN VNTR. Background.

Using genotyping IL-1 test, a pilot study was conducted on 32 Syrian patients with aggressive periodontitis (AgP) and 35 healthy controls to investigate the association between the IL-1α(-889), IL-1B(+3953) gene polymorphisms and AgP among schoolchildren. The results revealed a similar distribution of genotypes between patients and controls, and did not support an association between IL-1 gene polymorphisms and AgP, however, the association was significant in male patients only.

This comprehensive analysis of the subgingival microbiota in patients with PLS used 16S ribosomal RNA (rRNA) clonal analysis and the 16S rRNA-based Human Oral Microbe Identification Microarray (HOMIM).
Methods: Thirteen patients with PLS from seven unrelated families volunteered for this microbiologic study.
