Objective of the study was to evaluate the clinical status of the masticatory system in young adults with full permanent dentition and no stomatognathic system complaints. The study involved 186 randomly selected people with full dental arches with normal occlusal conditions corresponding to Angle's Class I aged 18 - 21 years with an average age of 19 years. Subjects were clinically examined and temporomandibular joint (TMJ) vibrations were recorded during open-wide and close movements using BioJVA. Then, patients were categorized into groups according to Piper's classification system...

Objective Temporomandibular joint dysfunction (TMD) may affect a patient's quality of life, and one of the etiologies can be anterior disc displacement with reduction (ADDwR) and anterior disc displacement without reduction (ADDWoR). Interleukin 1 Receptor 1 (IL-1R1) is a membrane receptor that plays an important role on initiating immune and inflammatory response by binding the agonists ligands of IL-1 alpha and IL-1 beta. Therefore, the aim of this study was to evaluate, through immunohistochemical analysis, the association of IL-1R1 with TMD...

Mandibular bone depression, also known as Stafne bone cavity, is defined as a bone depression filled mainly with salivary gland tissue. Parotid gland bone defects are infrequently observed. We report the case of a 52-year-old male patient who underwent radiographic examinations due to temporomandibular joint dysfunction, and a radiolucent area was detected in the mandibular ramus, with a provisional diagnosis of traumatic bone cyst or parotid mandibular bone defect. The patient was then referred for magnetic resonance imaging, which demonstrated a hyperintense area eroding the mandibular ramus, which corresponded to glandular tissue...

PURPOSE: Mandibular advancement devices are commonly used in the treatment of patients with mild to moderate obstructive sleep apnea (OSA). Designed to maintain the mandible in forced protrusion while being worn, mandibular advancement devices (MADs) are intended to increase the upper airway during sleep, thereby reducing OSA symptoms. Depending on the extent of mandibular protrusion, side effects including temporomandibular joint dysfunction are frequently reported. These are likely to reduce overall treatment success by affecting therapeutic adherence...

The objective of this study was to propose a treatment protocol for patients with lateral prognathism based on the unilateral sagittal split ramus osteotomy (USSRO). This was a prospective study involving 31 patients with lateral prognathism, who required a bilateral sagittal split ramus osteotomy (BSSRO). Two groups were formed using the proposed protocol, with specific inclusion criteria for each group: BSSRO (n=17) and USSRO (n=14). Occlusal parameters (dental midline deviation, overbite, and overjet) were measured preoperatively (T0), at model surgery (T1), 1 month postoperative (T2), and 1year after surgery (T3) and compared...

The oral and maxillofacial surgeon is instrumental in the management and care of pediatric patients with juvenile idiopathic arthritis (JIA) and should include JIA in the differential when evaluating pediatric patients with temporomandibular joint (TMJ) dysfunction. Medical management has largely decreased the need for surgical intervention, but these patients may require intraarticular steroid injections of the TMJ, close follow-up to monitor their facial growth, and management of the subsequent postinflammatory degenerative TMJ changes...

The incidence of tumors and pseudotumors of the temporomandibular joint (TMJ) in the pediatric population is low. They are often challenging to recognize unless associated with signs and symptoms that may erroneously be interpreted as TMJ dysfunction. Tumors of the TMJ can be divided into 3 categories based on the nature and type of precursor cell involved in the tumor: benign tumors, malignant tumors, and pseudotumors. This article discusses the most common entities in these categories.

Temporomandibular disorders (TMD) are a subgroup of craniofacial pain problems involving the temporomandibular joint (TMJ), masticatory muscles, and associated head and neck musculoskeletal structures. These disorders are subclassified into TMJ articular disorders and masticatory muscle disorders. Patients with TMD most commonly present with pain, restricted or asymmetric mandibular motion, and TMJ sounds during mandibular movements. The prevalence tends to increase with age. Management of TMJ articular disorders consists of a combination of patient education, home-care plan, biobehavioral therapy, physical therapy, orthotic jaw appliance therapy, pharmacotherapy, and/or surgery...

Temporomandibular joint (TMJ) osteoarthritis (OA) is a disease of the bone, cartilage, and supporting tissues of the joint. Patients with advanced TMJ-OA often have symptoms such as pain, swelling, and joint dysfunction, and they sometimes require surgical intervention when conservative treatment is not effective. The etiology of TMJ-OA remains elusive. The usefulness of 4-dimensional (4D) computed tomography (CT) in motion analysis of various joints has recently been reported. This article introduces a novel imaging technique of 4D CT that aims to identify kinematic features that may be associated with the etiology of TMJ-OA...

Temporomandibular joint disorders (TMDs) usually present with symptoms and signs such as pain, mandibular movement, dysfunction, or joint sounds. Botulinum toxin type A (BTX-A) is a biologic toxin which inhibits skeletal muscle through hindering the production of acetylcholine in the nerve endings. This toxin is used for the treatment of hyperactivity of lateral pterygoid muscle and TMD symptoms. This comprehensive review aimed to evaluate the effect of BTX-A injections in the lateral pterygoid muscle on treatment of TMDs symptoms...

Currently, there are three major groups of dentists who provide orthodontic services to the public: postgraduate trained orthodontists, postgraduate trained pediatric dentists, and general dentists who have taken various orthodontic training courses. All of them can expect to encounter a variety of clinical situations that require a proper understanding of how normal temporomandibular joints (TMJs) function, and also how the masticatory system can develop pain-dysfunction problems; those problems are classified and defined as temporomandibular disorders (TMDs)...

Osteoma is a benign osteogenic tumor, which is characterized the slow-growing proliferation of compact or cancellous bone. The etiology of the lesion is not well established. Among the hypotheses, the following are related: a traumatic factor, infectious processes, or true neoplasm due to the origin of cartilaginous cells. It can present at any age, usually in young adult individuals, with equal prevalence in both sexes. The clinical characteristics of the peripheral osteoma are represented by slow asymptomatic growth, which leads to swelling and, thus, facial asymmetry...

According to epidemiological data, muscular dysfunctions of the masticatory system occur in 15-23% of the population. Preventive examinations of functional disorders of the stomatognathic system are, therefore, of particular importance. A distinct group of patients exposed to dysfunctions in the area of the masticatory organ locomotor apparatus comprises those with genetic diseases characterised by disorders in collagen formation. One of such diseases is osteogenesis imperfecta (OI) and dentinogenesis imperfecta that usually goes together with the former...
