Abstract:

Abstract Objective The alveolar prominence can change the morphology of the mandible by showing continuous remodeling. The chronic remodeling/resorption process of the jaw is influenced by gender, genetics, systemic conditions, sequence of tooth loss, duration of edentulism and other unknown factors. Our aim in this study is to investigate the effect of continuous trauma to the maxillofacial region on the morphology of the mandible in defense athletes. Methods: In the study, the patients who applied to the Atatürk University of Dentistry, Department of Oral, Dental and Maxillofacial Radiology

Abstract:

Osteoporosis is a pandemic, chronic, silent skeletal condition that can cause bone fractures and possibly disability if left untreated. In clinical practice, it frequently goes unnoticed until a fracture develops. Therefore, the study aims to evaluate visually the diagnostic efficacy of panoramic-based mandibular cortex index and trabecular patterns in aged women.Archival Panoramic radiographs of 800 aged women were examined and narrowed to controls (114) and study patients (116).

Abstract:

Background: Bones will experience a decrease in density due to an imbalance in the process of resorption and remodeling. Women are known to be at greater risk of bone density loss than men, due to aging and hormonal effects. Decreased bone density can also affect alveolar bone and attachment to teeth, leading to tooth loss and edentulous. Panoramic radiographs are one of the regular examinations at dental clinics. They observe changes in the thickness of the cortical bone of the mandible and detect abnormalities in bone density by measuring them using the Mental Index (MI). Objectives: T

Microscopic examination revealed a tumor similar to ameloblastic fibrosarcoma, with atypical mesenchymal cells; however, the odontogenic epithelium also showed atypia. In the second case, a 16-year-old female had a painless, asymptomatic, large intraosseous mandibular lesion.

Abstract:

Obstructive sleep apnea (OSA) in children is one of the most common problems encountered by the otolaryngologist. It was described frequently in adults but was not clearly defined as of true medical significance in children until 19761. Since then, rapid advances in technology and increasing recognition have propelled pediatric sleep apnea into both fame and notoriety.  Snoring is the hallmark of sleep disordered breathing. It occurs in up to 27% of school aged children 2-10 and peaks at 2-8 years. This is coincident with the peak in size and degree of immunologic activity of the t

Abstract:

Mandibles of termite workers present distinct patterns according to the type of material they deal with when foraging and building, being hence useful to distinguish functional groups. This is hardly suprising as, being the tools most frequently and intensely used by workers, mandibles should be constantly subjected to selective forces. If worker mandibles reflect evolutionary pressure one could hence hypothesize that mandible patterns of workers of termite hosts would differ from those of termite inquilines. After all, host and inquilines differ, if nothing, on their differential investment i

Background Early detection of mandibular bone changes is critical for preventing complications during dental surgeries. Radiographic assessment of mandibular trabeculae using visual index assessment and fractal dimension (FD) analysis represents a significant advancement in dental diagnostics. These approaches enhance the identification of individuals at risk of low bone mass and facilitate the monitoring of bone changes, thereby optimizing treatment planning.

All six jaws can be unequivocally allocated to Lacertidae and five of those are allocated to European green lizards of the Lacerta viridis group. Currently, La. viridis has regionally extinct or probably extinct status in Poland.
