AI Article Synopsis
- The study investigates how painful temporomandibular disorders (TMDs) and myopia affect muscle activity, sensitivity, and sleep quality in individuals, classifying participants into four distinct groups based on their conditions.
- Results indicate that those with both myopia and TMDs experience increased muscle tenderness, altered bioelectrical activity in their muscles, and poorer sleep quality compared to other groups.
- The findings suggest a link between visual issues and muscle function, highlighting the need for further research on how refractive errors could impact muscle behavior during similar studies.
Article Abstract
The main aim of this study is to evaluate the effects of painful muscle form of temporomandibular disorders and myopia on the connections between the visual organ, the bioelectrical activity and sensitivity of the masticatory and cervical muscles, and sleep quality. Subjects were divided into 4 groups (Myopia & TMDs, Myopia (Without TMDs), Emmetropic & TMDs and Emmetropic (Without TMDs)). The study was conducted in the following order of assessment: examination for temporomandibular disorders, assessment of the muscle activity by electromyograph, pressure pain thresholds examination, ophthalmic examination and completion of the Pittsburgh Sleep Quality Index. It was observed that the Myopia & TMDs group had higher muscle tenderness, higher resting and lower functional muscle bioelectrical activity. The visual organ is clinical related to the masticatory and cervical muscles. TMDs and myopia alter masticatory and cervical muscle activity. The thickness of the choroid in people with myopia is related to muscle tenderness. TMDs and myopia impair sleep quality. It is recommended to determine the number of people with refractive error and its magnitude in the sEMG study in order to be able to replicate the research methodology.

Hemangiomas are benign congenital vascular tumors that commonly arise in the head and neck regions. Although they present with indolent growth and involution in most cases, they can cause facial deformities. Hemangiomas have three subtypes: capillary, cavernous, and mixed.

The purpose of this study was to investigate the clinical course of masticatory function recovery following an endoscopic-assisted open reduction and internal fixation (EAORIF) procedure. Patients with a unilateral mandibular condylar fracture who underwent EAORIF for therapeutic purposes were evaluated, with comparisons made between those who underwent the procedure for base or neck fractures. At each time point analyzed after treatment, the occlusal contact area and maximum bite force in patients with a base fracture were greater, although the differences between the groups were not significant.

This study evaluates the stress distribution in mandibular molar teeth with external cervical resorption restored using various restorative and biomimetic materials through finite element analysis. A mandibular first molar was scanned to create a 3D model. 'Class 2Bp' external cervical resorption defects were simulated on the buccal aspect and restored with different materials.

Introduction: The "All-on-four" technique addresses this by placing two vertical implants in the anterior region and two posterior implants angled up to 45°. This study evaluates stress distribution on bone, implants, abutments, gingiva, and prostheses based on posterior implant angulation, using both standard and angled neck implants. Additionally, angled neck implants were used alongside standard implants.
