Related papers
Temporomandibular joint (TMJ) disorders have multifactorial aetiology and manifests as a painful condition in the orofacial region and have a high prevalence rate among different populations. The aim of the study was to assess the prevalence of TMJ disorders among patient visiting the outpatient department (OPD) of a dental college situated in Jharkhand.A total of 8,000 people visiting the OPD of Dental College in Jharkhand were screened for a period of 6 months, and out of them, 100 patients were having temporomandibular disorders (TMDs). Five parameters were evaluated, and positive as well as negative findings were recorded. Females were found to be more affected with TMDs than males in the 19-29 years age group. Clicking was the most common symptom among the parameters that were analyzed. Dental professionals need to educate and motivate the patients to take up preventive measures and early treatment to maintain and prevent TMJ manifestation.

Aim and objective: To determine the prevalence of the signs and symptoms of temporomandibular joint disorders (TMDs) among dental students in Navi Mumbai. Materials and methods: A representative population-based sample of 500 dental students was evaluated for the signs and symptoms of TMD by means of a validated questionnaire. A detailed case history was taken, and the examination of the temporomandibular joint (TMJ), mandibular movements, muscles and occlusion was done for each participant. Results: The signs and symptoms of TMD are frequent among dental students. Out of 500 students, who filled the questionnaire and underwent examination, 250 were females and 250 were males. In total, 22% of the study population had at least one symptom of TMD. In total, 51% of the study population had at least one sign of TMD. The prevalence of the signs and symptom of TMD was significantly higher in females than in males. Conclusion: The study showed that about 29% of the study population had at least one sign without any symptoms of TMD. This highlights the presence of subclinical cases that exist in the population that can be intervened to prevent their progression into TMD. Clinical significance: Extra emphasis should be given on the determination of the predisposing, initiating and causative factors of TMD along with the examination. Prevention and treatment at an early stage will prevent the progression of TMD.
Prevalence of degree of severity of temporomandibular joint disorder based on sex and age group
2009
Temporomandibular joint disorders are disturbances of mastication system due to one or more component of mastication system does not properly function. The factors that play a role in this problem divided into three factors; a) predisposition factor (systemic, occlusion disturbances and psychological trouble), b) initiation factor (traumatic) and c) perpetuation factor (social behavior). These disorders are able to cause a variety of symptom suck as limitedness of jaw movement, clicking, deviation locked joint, muscle pain, joint pain, jaw movement pain and pain of ear and headache. The objective of this study was to obtain information about the prevalence degree of severity of the temporomandibular joint disorder, the differences of prevalence between man and woman and the different among age groups. The study was descriptive and analysis survey, done to 134 patients as an experimental sample of 3–75-year old that have visited Dental Hospital, Padjadjaran University Bandung, during...

Background: Temporo-mandibular disorders is a collective term used to describe problems involving muscles of mastication and temporomandibular joint. The study aimed to evaluate the prevalence of temporo-mandibular disorders and its association with parafunctional habits in patients visiting department of dentistry, Patan Academy of Health Sciences. Methods: A cross-sectional study was carried out among 213 patients coming to Patan Academy of Health Sciences. A screening questionnaire recommended by American Association of Orofacial Pain was used to determine the signs and symptoms of temporo-mandibular disorders. Results: The prevalence of temporomandibular disorders was 31.9 %. The three most common parafunctional habits were chewing gums (32.4 %), mouth breathing (19.7 %) and biting of objects (14.6 %) respectively. Statistically significant association was found between nail biting, grinding of teeth, biting of lips and objects and mouth breathing with signs and symptoms of temporomandibular disorders (p<0.05). Among the signs and symptoms of temporomandibular disorders, getting headaches, neck pain or toothaches often was the most frequent signs of temporomandibular disorders (n=105, 49.3 %). Feeling of recent change in bite was the second most frequent sign reported by 82 participants (38.5 %). Conclusions: The parafunctional habits between nail biting, grinding of teeth, biting of lips and objects and mouth breathing have statistically significant association with signs and symptoms of temporomandibular disorders.
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.

subject in the communities of researchers. Most authors consider occlusal anomalies as a fundamental factor in causing the symptoms, while other studies suggest that occlusal dysfunctions represent only one of the numerous factors associated with temporomandibular joint disorder (Landi et al 2012; Pullinger et al 1993; Sipila et al 2012). The occlusal factors must be analyzed both static and dynamic. Most of the studies carried out until now evaluated the static occlusal relationships, analyzing the degree of involvement in the etiology of TMD as isolated factor. Pullinger, Seligman and Gornbein realized a multifactorial analysis in order to determinate the degree of influence of each occlusal factor in association with other factors. Eleven occlusal factors were taken into consideration, being compared patients with signs and symptoms of TMD, with a group of healthy subjects. The authors concluded that many occlusal parameters, traditionally considered with increased influence in appearance of TMD, actually have little contribution in developing this disease, dental occlusion therefore cannot be considered the most important etiologic factor in TMD (Pullinger et al 1993). Several epidemiological studies have identified an association between facial pain and/or TMD and different forms of occlusal dysfunction such as medialized occlusion, cross occlusion, Abstract. Objective: This study aimed at assessing occlusal characteristics and their relation with sign and symptoms of temporomandibular joint disorder in a population group. Material and methods: Two hundred thirteen fourth year dental medicine students (mean age of 23±4.24 years) were evaluated according to Research Diagnostic Criteria for Temporomandibular joint Disorder form, but the examination also included additional procedures. Results: Pain in the oro-facial muscles was more frequent in female patients comparing to males. Articular and muscular pain is more frequent among subjects with interferences during the slide between Centric Relation and Maximum Intercuspation (articular p=0.038, OR 3.089, CI 95%, 1.066-8.954), muscular p=0.045, OR 3.771, CI 95%, 1.031-13.793). They can determine contractions of the masticatory muscles, affecting more often trapezius muscle (p=0,04), lateral pterygoid muscle (p<0.001), SCM (p=0.003) or milohyoid (p<0.001). A higher probability for joint clicks development is encountered in cases with accentuated Wilson curve (p=0.014, OR 17.285, CI 95%, 1.774-168.454). Conclusions: Occlusal characteristics can influence the articular and muscular status in the oro-facial area. These results indicate that clinicians should pay special attention to the temporo-mandibular joint status of patients with abnormal Spee or Wilson curves or presenting interferences during the slide from centric relation to maximum intercuspation.
Temporomandibular joint disorders – a lookback in time
International Journal of Dental Research, 2017
The variety of terms used has contributed to a great amount of confusion that exists in this already complicated field of study. Lack of communication and coordination of research efforts often begins with differences in terminology. Therefore in an attempt to coordinate efforts, the American Dental Association began to use TMD to include all functional disturbances of the masticatory system. The article reviews the research work done by various authors pertaining to the disorders of the temporomandibular joint.

BACKGROUND Temporomandibular joint (TMJ) is mostly prone to various dysfunctions or abnormalities, even with a slight alteration in its normal function. Dental treatments in particular are known to cause stresses on this joint causing complications such as pain, tenderness, restricted movement, clicking sound etc. It can become severe with time and interfere in the daily living activities and affect the quality of life (QOL). Hence, this study was done to focus on a few common dental conditions to determine their effects on TMJ. The objective of this study was to evaluate the prevalence of TMJ dysfunction in dental patients with varying treatment durations. METHODS A total of 130 male and female dental patients who underwent /were undergoing various dental treatments were included, on the basis of age (18 - 45). The total number of samples were collected from 6 categories i.e., endodontic, orthodontic, cleaning / scaling, tooth extraction, filling, multiple treatments. FONSECA’S que...
Current Concepts About Temporomandibular joint disorders: A Review Article
Journal of Research in Medical and Dental Science, 2020
Temporomandibular joint is formed by the mandibular condyle inserting into the mandibular fossa of temporal bone. It’s considered as ginglymoarthroidal joint which mean that is capable of both hinge type and gliding movements. TMD affects up to 15% of adults, with a peak incidence at 20 to 40 years of age. However, it can be classified as intra-articular or extra- articular. The incidence varies from 21.5% to 50.5%. The prevalence of TMD is about 3.7-12% greater in women than men. There are two types of treatment: conservative and surgical. We all believe that the valid diagnosis is the key to successful treatment on account of TMD multifactorial nature and often of patients suffering from other disorder simultaneously that can make the correct diagnosis difficult. Manual TMJ inspection was and remain self-evident manner used to detect joint dysfunction related to clinical findings. The primary study should be plain radiography (transcranial, trans maxillary views) or panoramic radi...
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.
