Pain-related temporomandibular joint disorders (TMJD) are a major public health problem, including the diagnoses of disc displacement (DD) with and without reduction (DDwR/DDwoR). The study aimed to examine the matrix remodeling and the inflammatory profile in synovial tissues of patients with TMJ-DD, with a view to understand the pathophysiology, and to contribute to the development of tissue-based diagnostic criteria. This laboratory-based observational case-control study included 30 synovial tissue samples obtained from 30 patients, diagnosed with delayed (DO) or sudden (SO) onset of DDwoR, which were compared against the reference patient material, DDwR ( = 10/diagnosis group).

Ther is a consensus to perform minimal invasive interventions as first-line surgical treatment since there are no evidence on best surgical practice yet.
Objective: The aim was to perform a complex systematic review (SR) on the topic-is there evidence for surgical treatment of TMJ DD?
Methods: The PICO was defined as DD patients (population), treated with different surgical interventions including arthrocentesis (intervention), compared with other or no treatment (control) regarding the outcome variables mandibular function, mouth opening capacity, TMJ pain, etcetera (outcome).
The primary aim of this study was to investigate whether patients with end-stage temporomandibular joint (TMJ) disease treated with gap arthroplasty with temporalis interpositional flap (GAT) had improved maximal interincisal opening (MIO) and TMJ pain in a long-term perspective. All patients with severe osteoarthritis, or fibrous or bony ankyloses, and subjected to GAT between 2008 and 2015 were included. The criteria of treatment success were TMJ pain VAS score ≤4 and MIO ≥30 mm.

Study Design: A prospective observational cohort study including 97 consecutive patients scheduled for TMJ surgery was performed. Joint mobility and several other predefined clinical variables were recorded.
Background: Synovial tissue is known to be the origin of inflammation in joint disease. Despite this, synovial fluid is the main biological specimen of choice in temporomandibular joint (TMJ) inflammation and pathology biomarker research. No comparison of TMJ protein content between synovial fluid and synovial tissue has been made.

Characterising the protein profile, as well as mapping clinical preoperative variables, might increase our understanding of pathogenesis and forecast surgical outcome. A cohort of 100 patients with either disc displacement, osteoarthritis, or chronic inflammatory arthritis (CIA) was prospectively investigated for a set of preoperative clinical variables.
View Article and Find Full Text PDFBackground: Symptomatic disc displacement (DD) of the temporomandibular joint (TMJ) may cause pain and limited mouth opening. The aetiopathogenesis is obscure and probably complex, which makes the diagnostic classification crude and mainly based on clinical criteria rather than disease mechanisms, and tissue characteristics.
Objectives: The study aim was to characterise and quantify synovial tissue in DD, where specific cytokine patterns might serve as potential biomarkers.
Temporomandibular joint (TMJ) disease classification and subsequent treatment selection are highly debated subjects within dentistry and medicine. Several suggestions for diagnostic classification and treatment algorithms have been proposed thus far without achieving a clear gold standard. A universally accepted diagnostic classification is essential for therapeutic decision-making as well as a prerequisite for prognostic evaluation and is necessary for achieving research results that are reproducible, comparable, relevant, and applicable in the clinical setting.

The objective of this study was to investigate various factors and their possible correlation with an unsuccessful outcome of arthroscopic lysis and lavage in patients diagnosed with chronic closed lock, arthralgia with or without concomitant osteoarthritis of the TMJ, or systemic rheumatologic disease with involvement of the TMJ.
Materials And Methods: A retrospective analysis of 224 operations was conducted to identify pre-, peri-, and postoperative factors correlated with an adverse outcome.

Purpose: To estimate the incidence of bisphosphonate (BP)-related osteonecrosis of the jaw (BRONJ) associated with the use of oral BPs and osteonecrosis of the jaw (ONJ) not associated with current or previous medication with a BP or radiotherapy to the head and neck region (background ONJ) in Sweden.
Materials And Methods: A survey was sent to all oral and maxillofacial surgery clinics and hospital dental clinics in Sweden. They were requested to report all new cases of BRONJ and background ONJ during 2007 and 2008.
