Purpose: to investigate the possible association between the severity of the temporomandibular disorder, cervical pain, and mandibular function impairment. Methods: is a cross-sectional, descriptive study, conducted with 32 individuals with temporomandibular disorder, categorized by degree of severity, according to the Fonseca Index. Using the diagnosis criteria for temporomandibular disorder, the likely etiological factors for the disorder were established, as well as the intensity of the functional disability, resulting from cervical pain and of the mandibular impairment. The data obtained were statistically treated, adopting the significance level of 5%. Results: the mean age was 33.8 years, 90.6% being females. As for the degree of disorder, 56.3% presented severe TMD, followed by 28.1% showing a moderate one. The myogenic etiology was present in 93.7% of the patients.

Background and Objective: The growing public interest in oral health has increased the demand for treatment of temporomandibular disorders (TMD). It is therefore important to have epidemiological data to estimate the proportion and distribution of these disorders. To the best of our knowledge, there are no reports on Nepalese citizens. Thus a study was designed to evaluate the prevalence and severity of TMD in undiagnosed health science university students. Materials and Method: The Fonseca questionnaire was administered to all undergraduate dental students at B.P. Koirala Institute Of Health Sciences willing to participate and fulfilling the inclusion criteria. Data entered in excel sheet and analyzed using SPSS. Results were analyzed using the frequency distribution of the questionnaire answers according to the Fonseca's anamnestic index. Results: 160 students (95 females and 65 males) with an average age of 21.49 years enrolled in the study. 31.85% showed some level of TMD: 28.125% mild TMD, 3.75% moderate and 0% severe. Women were the most affected group, with 21.87% showing some level of TMD against 10% of men, though the presentation not being statistically significant. Students with any level of TMD showed marked characteristics: 41.25% considered themselves tense people, 39.37% reported a frequent headache, 28.75% reported TMJ clicking, 28.12% had muscular pain while chewing, 25% clenched their teeth and 22.5% reported neck pain. Within these characteristics, significant gender difference was observed for headaches with higher female predominance. Conclusion: In contrast to other studies we observed a low prevalence and severity for TMD in the study population.

The primary objective of this study was to assess the prevalence of temporomandibular disorders (TMDs) and comorbid factors (sleep bruxism and headaches). This study was a cross-sectional population survey in the city of Maringá, state of Paraná, Brazil. Materials and Methods: Axes I and II of the Research Diagnostic Criteria for TMD (RDC/TMD) were used for assessment of TMD signs and symptoms. The population was users of the Brazilian public health system (SUS), of both sexes, between the ages of 20 and 65 years, and not seeking treatment for TMD. Results: The selected population (N = 1,643) was composed mostly of (a) women (65.9%), (b) married or single individuals (90.6%), (c) Caucasians (70.1%), (d) individuals aged 32.7 ± 10.3 years, (e) individuals earning a medium income (75.1%), and (f) those who had completed a high school education or higher (79.9%). According to the chronic pain grade classification (CPG) in the RDC/TMD Axis II, 36.2% of the population had some degree of TMD pain (CPG I to IV); however, only 5.1% had severe limitation due to pain (CPG III or IV). In the RDC/TMD Axis I diagnoses, 29.5% presented with muscle disorders (group I), 7.9% with disk displacements (group II), and 39.1% with other joint disorders (group III). Headaches were present in 67.9% and awake and sleep bruxism in 30% and 33.4% of the population, respectively. The prevalence of signs and symptoms of TMD was high in this population, but with low disability; however, the proportion of patients in need of treatment was much lower.

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.

Temporomandibular disorders in 19-year-old Korean men
Journal of Oral and Maxillofacial Surgery, 2002
Purpose: The purpose of this study was to determine the prevalence and the nature of the relationships between 3 temporomandibular joint disease (TMD) symptoms and symptoms of associated structures. Materials and Methods: This study was designed to rule out the effect from the uneven composition of the samples on TMD symptoms. The samples were collected from subjects who were of the same age, gender, district, and race. Nineteen-year old men (n ϭ 27,978) were selected and investigated by means of questionnaires and clinical examinations. The prevalence of each symptom was studied and tried to determine the effects of the TMD-associated signs on the TMD signs. The indices allocated to reflect the TMD signs and symptoms and the others were dichotomized for bivariate analysis. The predictor variables were headache, neck pain, referred pain, stress, past trauma history in the TMJ, past TMJ dislocation, bruxism, and clenching. The outcome variables were mouth opening limitation, TMJ pain on rest, and TMJ pain during function. Results: The incidence of masticatory muscle stiffness was 17.8%; TMJ sounds, 14.3%; headache, 7.2%; neck pain, 13.5%; bruxism, 8.4%; and clenching, 9.9%. Stress occurred in 12.8%, past trauma history in 11%, and previous joint dislocation in 2.5%. The experience of dislocation in the TMJ was found to be the most important risk factor in terms of mouth opening limitation (odds ratio, 4.08, P Ͻ .0001), joint pain during function (odds ratio, 5.50, P Ͻ .0001), and joint pain in the rest state (odds ratio, 4.63, P Ͻ .0001). Referred pain and the experience of trauma in TMJ were the secondary risk factors in terms of joint pain and referred pain and the stress in terms of mouth opening limitation. Considering referred pain can be induced by TMD, stress may be more related to mouth opening limitation (odds ratio, 2.18, P Ͻ .0001), and the experience of trauma in TMJ may be more related to pain in the rest state (odds ratio, 2.56, P Ͻ .0001) and during function (odds ratio, 2.47, P Ͻ .0001). Conclusions: The prevalence of TMD signs and symptoms as determined by this examination was in accord with the findings in women or mixed samples of other workers. Prior experience of a dislocated disc was found to be the most risky factor in TMD. Stress was related to limitations of mouth opening, and the experience of trauma in the TMJ was found to be related to pain in the joint region. Bruxism may not be a direct risk factor in TMD, and the clenching habit found to be more harmful than bruxism.
