Prevalence of temporomandibular joint disorders in patients: An institutional-based study
SRM Journal of Research in Dental Sciences, 2020
Temporomandibular disorders (TMDs) represent a class of conditions influencing the temporomandibular joint (TMJ), the muscles of mastication, and/or related structures. Muscles associated with and incorporating the jaw joint control its position and movement. The TMJ associates the mandible to the temporal bone. TMDs is an aggregate term that depicts a subgathering of painful orofacial disorders, including grievances of agony on the TMJ region and exhaustion of the cranio-cervico-facial muscles, especially of masticatory muscles, impediment of mandibular movement, and the presence of articular clicking. TMJ dysfunction is a cryptic issue even today because of its multifactorial etiology. However, it is generally assumed that TMDs would mainly affect adult patients; nevertheless, children have also shown a similar incidence. The aim of the study was to assess the prevalence of TMJ disorders among patient visiting the outpatient department (OPD) of a private dental college situated in Haryana.
The temporal-mandibular joint composes one of the most important articulations in the skull anatomy, aiding in such essential functions as articulation, mastication among other facial-oral functions. Proper functioning of this joint is thus of paramount significance in day to day life, with the influence important factors including the integrity of the glenoid fossa, the menisci, articulating condyles as well as the support factors like the attaching muscles and ligaments. Mandibular pathologies are hard to diagnose with most patients individually devising relieving mechanisms and often adapting to the aches and pain that characterize the presentation, and dental clinical examination often may overlook the mandibular signs. This study's objective was to determine the proportion of dental students assessing temporal-mandibular joint disorders through the means of clinical examination among those attending Sharif Medical and Dental College Lahore. Randomly selected 120 students attending the clinic for TMJ complaints provided information for this study's findings.

Temporomandibular Joint Disorders- An Overview of Diagnosis and Treatment Options
Acta Scientific Dental Scienecs, 2021
Temporomandibular Joint (TMJ) Disorders is a lifestyle modulating disorder. Patients having this disorder go through a lot of pain, discomfort and restriction in the joint movement in day to day life. There are times when the patient is aware of the pain and discomfort but the diagnosis is not made on time, sometimes if the diagnosis is made the appropriate treatment is not started on time. These patients are passed on from doctors to doctors in search of an appropriate treatment. This article emphasizes on the need for the Dentist and Physician joining practice to understand the disorder along with the planning for the treatment. As TMJ disorders is a complex disorder requires right intervention in the right stage of the disorder. This article focuses on the various treatment options available till date for the management of TMJ disorders.

Introduction: This hypothesis-generating study was performed to determine which items in the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and additional diagnostic tests have the best predictive accuracy for joint-related diagnoses. Methods: One hundred forty-nine TMD patients and 43 symptom-free subjects were examined in clinical examinations and with magnetic resonance imaging (MRI). The importance of each variable of the clinical examination for correct joint-related diagnosis was assessed by using MRI diagnoses. For this purpose, "random forest" statistical software (based on classification trees) was used. Results: Maximum unassisted jaw opening, maximum assisted jaw opening, history of locked jaw, joint sound with and without compression, joint pain, facial pain, pain on palpation of the lateral pterygoid area, and overjet proved suitable for distinguishing between subtypes of joint-related TMD. Measurement of excursion, protrusion, and midline deviation were less important. Conclusions: The validity of clinical TMD examination procedures can be enhanced by using the 16 variables of greatest importance identified in this study. In addition to other variables, maximum unassisted and assisted opening and a history of locked jaw were important when assessing the status of the TMJ.

To identify associations between clinical symptoms of temporomandibular joint disorders and radiographic findings. Two hundred four adult patients (156 women, 48 men, mean age 40 years) with temporomandibular joint (TMJ) pain/sounds or changes in mandibular motion were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Bilateral sagittal corrected TMJ tomograms in closed and open positions were assessed for the presence of flattening, erosion, osteophytes, and sclerosis in the joint components and the range of mandibular motion. Logistic regression analyses were performed with the radiographic findings as the dependent variables and the following clinical variables as independent variables: opening pattern, maximal jaw opening, TMJ sounds, number of painful muscle/TMJ sites, duration of pain, presence of arthritic disease, depression and somatization scores, graded chronic pain, and age and gender. Coarse crepitus on opening/closing (od...
MULTIPLE ETIOLOGIES OF TEMPOROMANDIBULAR JOINT DISORDERS -A REVIEW REVIEW ARTICLE
MULTIPLE ETIOLOGIES OF TEMPOROMANDIBULAR JOINT DISORDERS – A REVIEW, 2019
Temporomandibular joint (TMJ), is a synovial joint, involves two bones particularly mandible and temporal bone. Since TMJ involve muscles of mastication and jaw movement therefore, its disorders damages surrounding tissues and minimizes its function. The etiology of TMJ disorders is complex and multifactorial including genetic, traumatic, inflammatory, degenerative and idiopathic disorders as well as behavioral factors (parafunctional habits). Generally females are more affected because of increased level of estrogen hormone affecting bone and cartilage; moreover, emotional factors (anxiety, stress and depression) are also higher in females compared to males. Genetic disorders of TMJ include many genes, which contribute in bone formation and inflammation mediation. This article is focused on etiology of temporomandibular joint disorders and involvement of certain genes and other predisposing factors leading to pathophysiology of its development. Information regarding TMJ disorders was retrieved through PubMed, Medline and other authentic search engines available in the University, information was collected through reviews, research, and epidemiological studies published up to 2016. This review article concludes urgent management is sought in 1-2% young children, 5% teenagers and 5-12% adults. In order to avoid any iatrogenic injury it is mandatory to do prior extensive and detailed physical examination of TMJ.

Objectives: The objective of this study is to evaluate frequency of temporomandibular joint disorder and its distribution in different age groups among male versus female population. Study Design: Descriptive cross-sectional study. Setting: Shahina Jamil Teaching Hospital, Frontier Medical and Dental College, Abbottabad. Period: December 2019 to May 2020. Material & Method: The study sample comprises of total 140 patients with TMD, meeting the inclusion and exclusion criteria. Fonseca’s questionnaire and Anamnestic Index were used to assess the subjective response and severity of TMD symptoms. WHO sample size calculator used to determine sample size. Consecutive sampling technique used. P-value<0.05 was considered significant. Results: The results are arranged and statistically evaluated. Overall, 45% answered positive to questions with respect to symptoms. Majority of patients reported positive for neck pain or stiff neck (16%) and muscular fatigue while chewing (17%). 50 % of patients suffering from TMD symptoms belong to Age Group 1 (15 – 35 years). 94.3 % female patients suffer from some degree of TMD. Based on Fonseca’s Anamnestic Index of severity, 65.9% of patients have Mild TMD symptoms, 18.9% with Moderate severity and 1.5% with severe symptoms of TMD. Conclusion: This study concludes that TMD are more common in females with age group of 15 – 35 years of age. The most prevalent symptom is muscular pain / tiredness of jaws during chewing and stiffness of neck. In this study sample, majority of patients suffer from Mild TMD symptoms Key words: Anamnestic Index, Fonseca’s Questionnaire, Prevalence of TMD, Temporomandibular Joint Disorder
A comparison between clinical and radiologic findings in 259 temporomandibular joint patients
The Journal of Prosthetic Dentistry, 1983
R esults from epidemiologic studies show that temporomandibular joint (TMJ) diseases are common.' Comparisons between clinical and radiologic data are scarce. Madsen' and Kopp and Rocklerj found no positive correlation between radiologic findings and the severity of pain or dysfunction in the TMJ. However, Kopp and Rockier) found that patients with TMJ crepitation showed a higher frequency of radiologic abnormalities than patients without crepitation. Subcortical sclerosis and reduced joint space were found to be positively correlated to loss of molar support. Based on an examination of 67-year-old individuals, Lysell' concluded that the occurrence of some type of deviant radiologic findings such as reduced joint space and structural bone changes was more common in persons with symptoms in the form of TMJ sounds, reduced opening capacity of the mouth, and/or tenderness of muscles on palpation.
Clinical view of the temporomandibular joint disorder
Acta clinica Croatica
Temporomandibular pain has a musculoskeletal origin because it occurs as a consequence of masticatory muscle function disorder and temporomandibular joint disorder. Most common diagnoses of disorders are disc displacement and osteoarthritis, but their comorbidity can also occur. Pain is the most common symptom, where chronic temporomandibular pain may con- tribute to the occurrence of psychological disorders in the patient population. Splint is the most widespread dental method of treatment but other, noninvasive methods of musculoskeletal pain treatment are also recommended. Electronic axiography is used for visualization of mandibular movements, in particular pathologic sounds in the joints. Mental health, although not so obvious in dental practice, can influence the need of a multidisciplinary approach to the patient with disorder of the temporomandibular joint.
