Degenerative Temporomandibular Disorders: An Assessment of Bone Trabecular Structure Using Fractal Analysis in Digital Panoramic Radiographs.

Introduction Fractal analysis has proved to be a salient tool to quantitatively assess the qualitative changes in the bone trabeculae of patients with hyperparathyroidism, osteoporosis, and various temporomandibular disorders, including osteoarthritis (OA) and rheumatoid arthritis of temporomandibular joint (TMJ), in several previous studies. The purpose of this study was to use fractal analysis to assess alterations in the trabecular pattern of the mandibular condyle in patients with degenerative temporomandibular disorders. Materials and methods This study comprised 98 subjects with 49 subjects in the study group and 49 subjects in the control group, aged 18-50 years.

Clinical Dilemma and the Role of Cone-Beam Computed Tomography in the Diagnosis of an Unusual Presentation of Central Odontogenic Tumor-A Case Report.

Cone beam computed tomography (CBCT) provides a detailed analysis of the dentition and of cortical and medullary bone free of superimposition inherent in radiographs, which are effortlessly plausible, easily available, and relatively inexpensive when compared with other cross-sectional imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). This article presents a case report of a 23-year-old male patient with a complaint of a mass in the right side lower back tooth region for the past 2 and a half months, which had the unusual presentation of prominent exophytic growth masking the central odontogenic tumor, wherein the diagnostic performances of CBCT in unveiling the diagnostic challenge that led to the clinical dilemma is emphasized. Routine radiographs such as orthopantomogram, mandibular occlusal view were taken along with CBCT, which accentuated the precise diagnosis in this case.

Envelopment technique and topographic overlays in bite mark analysis.

Aims And Objectives: The aims and objectives of our study were to compare four sequential overlays generated using the envelopment technique and to evaluate inter- and intraoperator reliability of the overlays obtained by the envelopment technique.

Materials And Methods: Dental stone models were prepared from impressions made from healthy individuals; photographs were taken and computer-assisted overlays were generated. The models were then enveloped in a different-color dental stone.

Analysis of time-dependent changes in Bitemarks on Styrofoam sheets.

Context: The scope of Bitemarks in forensic dentistry is widening as they help the forensic expert in identifying the perpetuator in medicolegal cases. The greatest challenge in Bitemarks analysis is the time-dependent changes produced in Bitemark patterns on various substrates at the scene of the crime.

Aims: To analyze the time-dependent changes in Bitemarks on Styrofoam sheets.

A comparative study of overlay generation methods in bite mark analysis.

Aim: To evaluate the best method of overlay generation out of the three methods, i.e., manual, photocopying, and computer assisted method.
