“…In general, when measured over the years, the type of study that most prevailed was once again in vivo (n = 51), followed by in vitro (n = 37, 30%). Such studies aimed at using mesenchymal stem cells to treat various joint disorders of the TMJ, mainly osteoarthritis, a disease characterized by chronic inflammation of the synovial tissue, as well as progressive cartilage degradation and remodeling of the subchondral bone [ 75 ]. Osteoarthritis is classified as articular TMD by the Diagnostic Criteria for Temporomandibular Disorders (DC/DTM) [ 76 ], an essential diagnostic tool used by clinical dentists and researchers.…”

Temporomandibular disorder (TMD) is an umbrella term used to describe various conditions that affect temporomandibular joints, masticatory muscles, and associated structures. Although the most conservative and least invasive treatment is preferable, more invasive therapies should be employed to refractory patients. Tissue engineering has been presented as a promising therapy. Our study aimed to investigate trends and point out future research directions on TMD and stem cells. A comprehensive search was carried out in the Web of Science Core Collection (WoS-CC) in October 2022. The bibliometric parameters were analyzed through descriptive statistics and graphical mapping. Thus, 125 papers, published between 1992 and 2022 in 65 journals, were selected. The period with the highest number of publications and citations was between 2012 and 2022. China has produced the most publications on the subject. The most frequently used keywords were “cartilage”, “temporomandibular joint”, “mesenchymal stem cells”, and “osteoarthritis”. Moreover, the primary type of study was in vivo. It was noticed that using stem cells to improve temporomandibular joint repair and regeneration is a significant subject of investigation. Nonetheless, a greater understanding of the biological interaction and the benefits of using these cells in patients with TMD is required.

“…However, little is known about its etiology and progression [4], and its pathogenesis has not yet been elucidated. The symptoms are soreness and pain of joints and corresponding muscles, difficulty in opening mouth or abnormal mandibular movement, accompanied by joint pain, headache, ear pain, dizziness and even tinnitus [5] Mainly through medical history and clinical examination, according to the international general RDC / TMD biaxial diagnostic criteria . Temporomandibular joint disc displacement is a high incidence of clinical lesions, which can be divided into reversible anterior disc displacement and irreversible anterior disc displacement (anterior disk displacement with or without reduction) [6].…”

The temporomandibular joint (TMJ) is the only bilateral joint of the human body, which bears important physiological functions such as opening and closing mouth. Temporomandibular joint disorders is the most common oral disease with a high incidence of 30-40 %. Sleep bruxism (SB) is a kind of parafunctional activity, characterized by the contraction of the mandibular muscles and clenching or molars. Studies have shown that bruxism is considered to play a key role in the occurrence and development of temporomandibular disorders (TMD) and is positively correlated with the incidence of TMD. However, the similarities and differences in the occurrence and mechanism of condylar and articular tubercle bone changes between temporomandibular joint disc displacement and bruxism have not been studied. Based on this, CBCT imaging was used to study the bone mineral density (condyle, joint nodules) of joints and the morphology of joint bone structure in patients with bruxism and temporomandibular joint disc displacement, so as to understand whether there are differences in the effects of reversible and irreversible displacement (disk displacement with or without reduction) displacement without reduction and bruxism on joint bone structure.We compare the changes of joint space and condylar bone structure between patients with bruxism and asymptomatic non-molars, to explore the influence of bruxism on temporomandibular joint, and to provide theoretical basis for clinical diagnosis and treatment of patients with bruxismtemporomandibular joint disorder.

“…The position of a mandibular condyle within the articular fossa can vary. Patients with a dentofacial deformity show a condylar position related to the morphological anatomy of the mandible [7]; in these cases, the morphology of the TMJ could be in an adaptation to optimize joint function in normality or joint disease [11]. It depends on variables such as age, sex, mechanical load conditions, and others.…”

Orthognathic surgery is indicated to modify the position of the maxillomandibular structure; changes in the mandibular position after osteotomy can be related to changes in the position of the mandibular condyle in the articular fossa. The aim of this study was to determine changes produced in the mandibular condyle 6 months after orthognathic surgery. A cross-sectional study was conducted that included subjects who had undergone bimaxillary orthognathic surgery to treat dentofacial deformity of Angle class II (group CII) or Angle class III (group CIII). Standardized images were taken using cone-beam computed tomography 21 days before surgery and 6 months after surgery; measurement scales were used to identify the condylar position and its relations with the anterior, superior, and posterior joint spaces. The results were analyzed using the Shapiro–Wilk and Student’s t-tests, while considering a value of p < 0.05 as indicating a significant difference. Fifty-two joints from 26 patients, with an average age of 27.9 years (±10.81), were analyzed. All subjects in both group CII and group CIII showed a significant change in the anterior, superior, and posterior joint spaces. However, postoperative changes in the position of the condyle in the articular fossa were not significant in the anteroposterior analysis. We conclude that orthognathic surgery causes changes in the sagittal position of the mandibular condyle in subjects with mandibular retrognathism and prognathism.
