A support vector machine-based algorithm to identify bisphosphonate-related osteonecrosis throughout the mandibular bone by using cone beam computerized tomography images.

Objective: This study aimed to develop an algorithm to distinguish the patients with bisphosphonate-related osteonecrosis of the jaws (BRONJ) from healthy controls using CBCT images by evaluating both trabecular and cortical bone changes through the whole body of the mandibular bone.

Methods: Patient data set was created from axial CBCT images of 7 BRONJ patients (28 slices) and 8 healthy controls (27 slices). The healthy bone of healthy controls, bone sclerosis of BRONJ patients, bone necrosis of BRONJ patients, and normal appearing bone of BRONJ patients (NBP) were labeled on CBCT images by three maxillofacial radiologists.

Results: Mann-Whitney U-test revealed no significant difference between two groups regarding mucosal thickening and apical bone measurements (P > 0.

Saliva levels of caspase-1, TNF-α, and IFN-γ in primary Sjögren's syndrome: oral mucosal abnormalities revisited.

Background/aim: Abnormalities in oral mucosal immunity contribute to complex pathogenesis of primary Sjögren's syndrome (pSjS). We aimed to measure saliva and serum levels of caspase-1, tumor necrosis factor-alpha (TNF-α) and interferon gamma (IFN-γ) in patients with pSjS. Materials and methods: We studied 43 pSjS patients fulfilling the AECG criteria and 30 age/sex-matched healthy controls, as well as 39 rheumatoid arthritis (RA) patients as a disease control group.

Clinical periodontal status and inflammatory cytokines in primary Sjögren syndrome and rheumatoid arthritis.

Background: The aim of the present study is to compare the clinical periodontal findings as well as gingival crevicular fluid (GCF) and plasma levels of tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), interferon gamma (IFN-γ) and caspase-1 in primary Sjögren syndrome (pSS) and rheumatoid arthritis (RA) subjects.

Methods: In the present case control study plasma and GCF samples were collected, full-mouth recordings comprising plaque index (PI), bleeding on probing (BOP) and probing depth (PD) were performed in 44 subjects with pSS, 39 subjects with RA and 30 systemically healthy subjects. Plasma and GCF TNF-α, IL-1β, IFN-gamma and caspase-1 levels were determined by enzyme-linked immunosorbent assay.

Does the state of dentition effect the type of stylohyoid chain calcification pattern?

Introduction: The human stylohyoid chain calcification patterns (SCP) present considerable anatomic variability. This study was performed to investigate the calcification on SCP in the dentate and total edentulous population and its relation to mandibular protrusive movement.

Materials And Methods: The study analyzed 1.

Impact of Buccotherm® on xerostomia: a single blind study.

Objective: The purpose of this single blind study was to investigate effects of Buccotherm® spray on subjective symptoms of xerostomia patients.

Methods: Twenty patients with dry mouth complaint were instructed to use placebo six times a day for 2 weeks. After a wash period, mineral water spray was provided.

Dental students' knowledge of characteristics and management of oral complications of cancer therapy.

Objective: The aim of this study is to investigate the level of Turkish senior dental students' knowledge regarding the orodental complications and their treatment methods of cancer patients.

Study Design: A 15-item questionnaire which was obtained from National Institute of Dental and Craniofacial Research that contained information about the orodental complications of the cancer therapy and the dentists' role to provide their treatment protocols was used. Seventy-seven senior dental students answered the questionnaire and the replies were analyzed with stratified and logistic data analyses.

Prevalence and pattern of stylohyoid chain complex patterns detected by panoramic radiographs among Turkish population.

Objective: The calcified stylohyoid ligament and the elongated styloid process (SP) are identified radiographically, are associated with several syndromes and symptoms. The aim of this study was to classify and determine the incidence of different types of stylohyoid chain patterns in Turkish population to provide a guide for the dentist and maxillofacial surgeon. The effect of menopause, on the elongation of SP was also investigated.

In vitro antimicrobial effects of commercially available mouth-wetting agents.

Products have been developed to provide palliation for persons with dry mouth. In addition to mouth-wetting agents, some products incorporate antimicrobial constituents with the goal of improving oral microbial defenses. The aim of this in vitro study was to investigate the potential antimicrobial and antifungal effects of two commercially available saliva substitutes on Streptococcus mutans, Lactobacillus acidophilus, and Candida albicans by using the agar-well diffusion method.

Perception of anatomical structures in digitally filtered and conventional panoramic radiographs: a clinical evaluation.

Objectives: The aims of the study were to compare subjective image quality of clinical images obtained with a storage phosphor plate (SPP)-based digital and conventional film-based panoramic system for the visualization of various anatomical structures and to evaluate the effect of various processing algorithms on image interpretation.

Methods: Panoramic radiographs were taken in 42 patients both with film and with a SPP system. SPP images were treated with shadow, sharpen, negative, greyscale sigma and greyscale exponential filters.

The efficacy of Xialine in patients with Sjögren's syndrome: a single-blind, cross-over study.

Sjögren syndrome (SS) is a chronic inflammatory autoimmune disease of unknown cause whose main characteristic is severe dryness of the eyes and the mouth. The decreased functional capacity of the lacrimal and salivary glands which is the result of the inflammatory process and lymphocytic infiltration observed in SS is accountable for this complication. Twenty-nine patients with SS whose ages were ranging between 24-77, who were under treatment in Ege University Faculty of Medicine Department of Rheumatology, participated in the study, and their informed consents were obtained upon enrollment.

Facial subcutaneous calcinosis and mandibular resorption in systemic sclerosis: a case report.

Systemic sclerosis (SSc) is an autoimmune disease characterized by widespread fibrosis of subcutaneous connective tissue, causing serious complications with the involvement of other systems. Tight, firm skin is the main characteristic of SSc, causing extrinsic pressure and the obliteration of the vessels. This then leads to ischaemia and destruction of the underlying bone.

Complete replacement resorption after replantation of maxillary incisors: report of case.

This article describes the treatment of a 17-year-old patient with complete root resorption of the maxillary permanent central and lateral incisors following avulsion and replantation seven years ago. The most important factor influencing the prognosis of replanted teeth is the status of the periodontal ligament (PDL). As a result of replantation, the PDL cells necrosed and tooth replacement resorption occurred.
