“…Despite being pathological conditions of the temporomandibular complex, incorrect occlusions caused by dental malocclusions and inadequately treated or untreated edentulism are not thought to be the primary causes of TMD (14). A low occurrence of certain malocclusional characteristics (negative overjet, one-sided open bite, one-sided cross bite of men, and edge-to-edge bite of women) with TMD symptoms or signs has been noted by Badel et al (15). In the same study, it was discovered that asymptomatic patients had considerably more hyperbalance and interference contacts than did TMD patients.…”

This contemporary review delves into the intricate realm of temporomandibular joint (TMJ) function and dysfunction, shedding light on its multifaceted nature and offering insights into diagnostic and therapeutic strategies. The TMJ, a vital component of the craniofacial complex, plays a pivotal role in everyday activities such as chewing, speaking, and yawning. Understanding its anatomy and physiology is paramount in the treatment and management of TMJ dysfunction. The biomechanics of TMJ function, from the articular disc to the surrounding ligaments and muscles, have been explored comprehensively. A critical aspect of this review revolves around the diverse etiological factors contributing to TMJ dysfunction. Genetic predispositions, parafunctions, occlusal irregularities, and psychological stress are dissected to illuminate the roles of these factors in the development of TMJ disorders. These complexities prompted the need for a robust classification system elucidating the clinical manifestations and diagnostic criteria for various TMJ disorders. Modern diagnostic modalities, including clinical assessment, imaging techniques, and joint aspiration, are scrutinized for their indispensable roles in accurate diagnosis. The comprehensive overview included management strategies, from conservative measures to surgical interventions. In recognizing the pivotal influence of psychosocial factors, this review underscores the importance of patient-centered care and cognitive-behavioral interventions. Furthermore, regenerative therapies, minimally invasive techniques, and personalized medicine are emerging trends in TMJ research. This review provides a contemporary roadmap for comprehending, diagnosing, and managing TMJ-related conditions.

“…Among the risk factors in this category, attention should be paid to alcohol [63] and tobacco use [64], use of opioids and/or cannabis [65,66], and obesity [67]. Several of these agents may also result in SB [68][69][70][71]. Furthermore, some anticonvulsants that amplify signaling via GABA-A receptors can elicit or exacerbate SA [72].…”

Objective The purpose of this study is to examine the pathophysiology underlying sleep apnea (SA). Background We consider several critical features of SA including the roles played by the ascending reticular activating system (ARAS) that controls vegetative functions and electroencephalographic findings associated with both SA and normal sleep. We evaluate this knowledge together with our current understanding of the anatomy, histology, and physiology of the mesencephalic trigeminal nucleus (MTN) and mechanisms that contribute directly to normal and disordered sleep. MTN neurons express γ-aminobutyric acid (GABA) receptors which activate them (make chlorine come out of the cells) and that can be activated by GABA released from the hypothalamic preoptic area. Method We reviewed the published literature focused on sleep apnea (SA) reported in Google Scholar, Scopus, and PubMed databases. Results The MTN neurons respond to the hypothalamic GABA release by releasing glutamate that activates neurons in the ARAS. Based on these findings, we conclude that a dysfunctional MTN may be incapable of activating neurons in the ARAS, notably those in the parabrachial nucleus, and that this will ultimately lead to SA. Despite its name, obstructive sleep apnea (OSA) is not caused by an airway obstruction that prevents breathing. Conclusions While obstruction may contribute to the overall pathology, the primary factor involved in this scenario is the lack of neurotransmitters.

“…Bruxism was originally thought to be a central nervous system problem, associated with anxiety, tension, and the release of stressful [4]. Recent studies have shown that bruxism may be caused by a synergistic effect of multiple factors, such as genetic factors [5], neuropsychological factors (long-term anxiety and tension) [6,7], physiological and pathological factors (malocclusion, snoring, sleep disorder) [8][9][10][11], and bad lifestyle habits (smoking, alcoholism, excessive caffeine intake) [12][13][14][15].…”

[Objective] Occlusal splints are always applied on individuals with bruxism to reduce tooth wearand relieve orofacial symptoms such as myofascial pain. The stomatognathic system ismainly composed of tooth, occlusion, masticatory muscles, and temporomandibular joint. The occlusion and masticatory muscles function are regarded as the important parameters for evaluating the stomatognathic system state objectively. However, the effects of occlusal splints on individuals with bruxism is rarely elucidated from accurate neuromuscular analysis and occlusion evaluation. The aim of the present study was to estimate the effects of three different splints (two clinically common full coverage occlusal splint and an modified anterior splint) on subjects with bruxism using K7-J5 neuromuscular analysis system and Dental Prescale II (DP2) to evaluate occlusion. [Methods] Sixteen subjects claimed to be suffering from nocturnal bruxism,with complete dentition and stable occlusal relationship, were selected for study.The intermaxillary space and the baselines of EMG-activity of the anterior temporalis and masseter were recorded for all the subjects. The participants was treated with three different splints, and outcomes were estimated by comfort index, occlusion and surface electromyography of anterior temporalis and masseter. [Results] At teeth clenched position, EMG data were significantly lower in the participants with use of modified anterior splint than with hard, soft occlusal splint or without splint (p < 0.05). The maximum bite force and bite area occur in subjects without use of splint , while the minimal occur in subjects with use of modified anterior splint. Intermaxillary spaceincreased and masticatory muscles presented significant reduction of EMG data at rest position as a result of J5 (p < 0.05). [Conclusion] Modified anterior splint seems to be more comfortable and effective in reducing occlusion force andelectromyographic activity of anterior temporalis and masseter for subjects with bruxism.

Abstract: Conclusion: Suicidality of breast cancer patients is associated with QOL domains but not with clinical characteristics of the illness. Decreasing of faith is associated with suicidality.
