Parafunctional habits

This review article describes the methods and clinical recommendations for reinforcing traumatized anterior immature teeth with pulp necrosis treated with mineral trioxide aggregate (MTA) apexification. Traumatic injury can cause pulp necrosis and incomplete root formation in immature teeth. MTA apexification is the treatment of choice for necrotic immature teeth, particularly during the middle or late stages of root development. MTA apexification has a high success rate; however, failures due to cervical or root fractures occasionally occur...

BACKGROUND AND AIMS: Bruxism is associated with a variety of factors, some of which are oral (occlusion, joint, face shape) while others are of a systemic nature (respiratory, cardiac, neurotransmitters, stress). The relationship between bruxism and occlusion has received great attention, but it still has a lot of ambiguity. This study aimed at investigating the parameters that may affect bruxism: dental interferences or premature contacts, vicious habits, temporomandibular joint (TMJ) pain, TMJ noises, TMJ morning fatigue, snoring, obstructive sleep apnea, which may occur before bruxism, or because of chronic parafunction...

This research fills a knowledge gap in bone tissue engineering by examining the mechanical characteristics of scaffolds at bone-tissue interfaces utilizing a cutting-edge technique involving the creation of 3D scaffolds from Polycaprolactone (PCL). The work employs Finite element analysis to measure the scaffolds' maximum principal and Von Mises stresses and strains. CT scans of the Maxilla and Mandible were used to apply load conditions to 3D models of the upper central incisor. In the derived computational model, four different load situations considered were: the masticatory load (70-100 N at 45°), two parafunctional habits (100-130 N) and 500-550 N at the incisal edge, both at 45°), and a trauma case (800-850 N applied perpendicularly from the inwards direction at 90°)...

BACKGROUND: Temporomandibular disorders (TMDs) are a heterogeneous group of conditions involving the temporomandibular joint complex, and surrounding musculature and osseous components. They are a multifactorial disease that can be determined by organic, genetic aspects, oral parafunctional habits, and psychological stress. They have an annual incidence of more than 5% of the population and about 6% to 12% of the population is affected by symptoms. The diagnostic criteria (DC), introduced by Dworkin, is considered the standard system to diagnose this disease in a specific way...

Symptoms of temporomandibular disorders (TMD) could be present as otologic symptoms like earache and dizziness in some patients. In most cases, these symptoms are not recognized because otolaryngologists fail to diagnose TMD as a source of the problem. This investigation was conducted to evaluate the effect of TMD treatments on the otologic symptoms which after taking history and clinical examinations seemed to be related to TMD. In the present study, the patients who were complaining of otalgia, ear fullness, tinnitus, hearing loss, and dizziness were evaluated by an ear fellow...
