Presence Of Temporomandibular Disorders Symptoms Research Articles

Prevalence and associations of temporomandibular disorders in older Brazilian adults.

The objective of the study was to estimate the prevalence of temporomandibular disorders (TMD) and describe associations in a representative sample of community-dwelling older Brazilian adults. TMD cause recurrent or chronic pain and dysfunction with substantial impacts on quality of life, but little is known of their occurrence and associated factors among older adults. This was a cross-sectional study using data from the second wave of the Brazilian Longitudinal Study of Aging, a nationally representative sample of older Brazilian adults aged 50 or older. The presence of temporomandibular disorder symptoms was measured by the Fonseca Anamnestic Index. Independent variables included sociodemographic characteristics, general health conditions and self-reported oral health measures. The association between the independent variables and TMD symptoms was evaluated using logistic regression models. Complete information for the variables of interest was available for 9391 individuals. The overall prevalence of TMD symptoms was 18.0% (95% CI 14.4-22.1). Relative to older adults aged 50-59 those in all age categories had lower odds of TMD symptoms. Individuals with depression, pain, sleep problems and self-reported poor general health had higher odds of reporting TMD symptoms. None of the oral health measures were related to TMD. The prevalence of TMD symptoms among Brazilian older adults is associated with demographic and general health conditions, but not with dentition status.

Pre-operative parafunctional or dysfunctional oral habits are associated with the temporomandibular disorders after orthognathic surgery: An observational cohort study.

Temporomandibular disorders (TMDs) are frequent and disabling, and hence, preventing them is an important health issue. Combining orthodontic and surgical treatments for malocclusions has been shown to affect temporomandibular joint (TMJ) health. However, publications regarding the risk factors that predict negative TMJ outcomes after orthognathic surgery are scarce. Present prospective cohort study was conducted to identify an association between pre-operative dysfunctional/parafunctional oral habits and the presence of TMD symptoms after orthognathic surgery. We included 237 patients undergoing orthodontics and surgical treatment for malocclusions associated with dentofacial deformities within the Department of Oral and Maxillofacial Surgery of the University of Lille. Their parafunctional and dysfunctional oral habits were recorded through clinical examination along with the presence of TMD symptoms before and after the surgery. According to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) classification, the TMD symptoms studied were myalgia, arthralgia, disc displacement with or without reduction. Multivariate analysis revealed significant associations among bruxism (odds ratio [OR] 3.17 [1.066; 9.432]), lingual interposition (OR 4.241 [1.351; 13.313]), as well as primary swallowing (OR 3.54 [1.225; 10.234]) and the presence of postoperative symptoms of myalgia. Moreover, a significant association was observed between the presence of any dysfunctional oral habit and postoperative disc displacement with reduction (OR 4.611 [1.249; 17.021]). Bruxism and dysfunctional oral habits were shown to be risk factors for the presence of TMD symptoms also after combined orthodontic and surgical treatment. Treating such habits before orthognathic surgery should help prevent TMD.

Relationship between Expanded Disability Status Scale scores and the presence of temporomandibular disorders in patients with multiple sclerosis.

Objectives:The objectives of this study were to assess the prevalence of temporomandibular disorders (TMDs) in patients with relapsing-remitting multiple sclerosis (MS) and to investigate whether an association exists between the presence of TMD symptoms and the degree of MS-related disability.Materials and Methods:In all, 120 individuals were evaluated: 60 patients with a diagnosis of relapsing-remitting MS and 60 age- and sex-matched controls without neurological impairments. A questionnaire recommended by the European Academy of Craniomandibular Disorders for the assessment of TMD symptoms was administered. For those who answered affirmatively to at least one of the questions, the RDC/TMD Axis I instrument was used for a possible classification of TMD subtypes. The Expanded Disability Status Scale (EDSS) was the measure of the degree of MS-related disability.Statistical Analysis Used:Fisher's exact test was used to analyze the data. ANOVA was used to detect significant differences between means and to assess whether the factors influenced any of the dependent variables by comparing means from the different groups.Results:The prevalence of TMD symptoms in patients with MS was 61.7% versus 18.3% in the control group (CG). A diagnosis of TMD was established for 36.7% in the MS group and 3.3% in the CG (P = 0.0001). There were statistically significant differences between degrees of MS-related disability and the prevalence of TMD (P = 0.0288).Conclusions:The prevalence of both TMD and TMD symptoms was significantly greater in the MS group. EDSS scores and TMD prevalence rates were inversely related.

Prevalence of signs and symptoms of temporomandibular disorders in college preparatory students: associations with emotional factors, parafunctional habits, and impact on quality of life.

The aim of this study was to evaluate the prevalence of temporomandibular disorders (TMD) signs and symptoms, its correlation with gender, parafunctional habits, emotional stress, anxiety, and depression and its impact on oral health-related quality of life (OHRQL) in college preparatory students at public and private institutions in João Pessoa, Paraíba (PB). The sample consisted of 303 students. Presence of TMD symptoms was determined by an anamnesis questionnaire containing questions related to the presence of parafunctional habits and emotional stress. A simplified clinical evaluation protocol was used. Anxiety and depression were determined with the Hospital Anxiety and Depression (HAD) scale and the OHRQL using the short version contained in the Oral Health Impact Profile (OHIP-14). The Chi-square, Fisher Exact, Mann Whitney, and Kruskal-Wallis tests were performed. Presence of signs and symptoms of TMD was statistically associated (p ≤ 0,05) with female gender, parafunctional habits, emotional stress, and anxiety, and represented greater impairment of the OHRQL. The physical pain domain was the most affected. The increased prevalence of signs and symptoms of TMD among college preparatory students indicates that there is a need for education and clarification among teachers and students to improve early diagnosis and to prevent the problem.

Retrospective review of patients referred to a temporomandibular dysfunction care setting of a Brazilian public university

ABSTRACT BACKGROUND AND OBJECTIVES: The objective of this study is to describe the restrospective analysis of medical records of patients with temporomandibular disorder in a healthcare service of a Brazilian public university. The prevalence of signs and symptoms of temporomandibular disorder, associated factors, diagnosis and observations related to the treatment were recorded. METHODS: Two hundred and thirteen medical records were assessed by one single surveyor from March 2013 to December 2014. Information about sociodemographic factors, prevalence of symptoms of temporomandibular disorder and treatment need were collected (Fonseca Anamnestic Index), clinical examination, diagnosis, treatments and referral to other professionals. RESULTS: The majority of patients were female (81.7%), single (53.0%), students (23.3%) between 20 and 29 years of age (26.8%). Pain was reported by 50.4% of patients. According to FAI, 41.8% of patients were classified with severe synptoms of temporomandibular disorder and 73.2% identified with the need of treatment. Presence of temporomandibular disorder symptoms (p = 0.001) and need of treatment (p <0.001) were significantly associated to the female gender. The most prevalent diagnosis was muscle temporomandibular disorder (41.5%) and the most affected muscle was the masseter (21.3%). The most common treatments were occlusal splint (27.6%) and counseling (22.6%). CONCLUSION: The greater demand for temporomandibular disorder treatment came from young patients, single, female, complaining from pain. The prevalence of temporomandibular disorder symptoms was high, muscular disorders was the most prevalent findings and most of the treatments were reversible and conservative. The frequency of referral to other specialties related to temporomandibular disorder was low.

Temporomandibular disorders and oral habits in high-school adolescents: a public health issue?

ABSTRACT Objective: Determine the prevalence of signs and symptoms of temporomandibular disorder (TMD) and its relationship with parafunctional habits in a sample of adolescents. Methods: The sample consisted of 129 high school students, between 16 and 19 years old in public schools. Data were collected through: a questionnaire about parafunctional habits and TMD symptoms, the Fonseca's index (DMF) and a summarized protocol of clinical evaluation of the TMD signals. These data were analyzed in a descriptive way, using statistical analysis by Chi-square test (x2) and Fisher's Exact test. Results: 84.5% of individuals showed a degree of auto-reported dysfunction. The most frequent parafunctional habit was chewing gum (65.9%) while the habit of biting objects was significantly associated with the presence of TMD symptoms (p = 0.042). There was a statistically significant association between TMD symptoms with variables such as gender (p = 0.032) habits (p = 0.014) and emotional stress (p &lt;0.01), besides the association between the need of treatment and gender (p = 0.002) and stress (p &lt;0.01). In addition, there was an association between muscle tenderness, unilateral mastication (p = 0.045) and chewing ice / lollipop (p = 0.04). Conclusion: It was concluded that there was not only a high incidence of signs and symptoms of temporomandibular dysfunction and parafunctional habits in high school students, but also an association among them, becoming necessary to establish public policies of prevention and access to treatment for these problems for that specific age group.

Efeito da prática de instrumentos musicais nas disfunções temporomandibulares e distúrbios do sono

The aim of this study was to evaluate the relation among recreational practice of musical instruments, temporomandibular disorders (TMDs), and sleep disturbances in a sample of musicians that are members of orchestras in a southeast area of Brazil. The participants practice playing instruments as a leisure activity. Method: this was a cross-sectional study with two groups. The comparison group included members from the general population. Both group included 43 adults, being 14 women and 29 men. The mean age of comparison group is 28.35 (±4.867), and the mean age of musician group is 28.37 (±6.712). The participants completed self-rated questionnaires to assess TMDs symptoms and sleep disturbance. Results: tThe groups did not differ regarding the presence of TMDs symptoms, sleep disturbance, and demographic variables. A strong and negative correlation was observed between TMDs and time of playing a musical instrument. The participants with less practice in years in playing a musical instrument have 8.57 more chance of having TMDs than the musicians with a long history of playing an instrument. Conclusion: it seems that a long history of practicing a musical instrument as a leisure activity is associated with a lower chance of developing TMDs. This study reinforces the benefits of playing a musical instrument as a leisure activity to physical health, specifically, as a protective factor to developing TMDs.

Prevalence of temporomandibular disorders symptoms in patients with multiple sclerosis.

The aim of the present study was to assess the prevalence of symptoms of temporomandibular disorders (TMD) in patients with the relapsing-remitting form of multiple sclerosis (MS), the relationship between TMD and the severity of MS, and the presence of TMD symptoms in the evaluated groups. Sixty individuals were evaluated: 30 patients diagnosed with relapsing-remitting MS and 30 control individuals matched for gender and age range with no neurologic pathology. In order to investigate the TMD symptoms, the questionnaires of the EACD (European Academy of Craniomandibular Disorders) and the RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders), both validated for TMD research, were administered. To assess the extent of disability produced by MS, the Expanded Disability Status Scale (EDSS) was used. The prevalence of TMD symptoms in patients with MS was 56.7% versus 16.7% for the control group, with a statistically significant difference between the groups (p=0.0016). No correlation was found between the severity of MS and the prevalence of TMD symptoms (Fisher's test, p=1.0).

Self-reported aural symptoms, headache and temporomandibular disorders in Japanese young adults

BackgroundTo investigate the associations of aural symptoms, headache and depression with the presence of temporomandibular disorder (TMD) symptoms in a young adult population in Japan.MethodsA personal interview survey was conducted on first-year university students (n = 1,930) regarding symptoms of TMD, aural problems, headache, shoulder pain and depression. Logistic regression was applied to assess the associations of these problems with the presence of TMD symptoms after controlling for age and gender.ResultsAmong the 1,930 students, 543 students exhibited TMD symptoms and were classified into 7 groups: clicking only (Group I, n = 319), pain in the TMJ only (Group II, n = 21), difficulty in mouth opening only (Group III, n = 18), clicking and pain (Group IV, n = 29), clicking and difficulty in mouth opening (Group V, n = 48), difficulty in mouth opening and pain (Group VI, n = 11), and combination of three symptoms (Group VII, n = 97). The control group (n = 1,387) were subjects without any TMD symptoms. After adjusting for age and gender, a strong association was observed between TMD symptoms (Group II and IV) and tinnitus (OR = 12.1 and 13.2, respectively). TMD symptoms (Group I, II and III) were also associated with vertigo and headache. Otalgia and depression were significantly associated with the presence of clicking only.ConclusionsTMD symptoms were significantly correlated to aural symptoms and headache. A functional evaluation of the stomatognathic system should be considered in subjects with unexplained aural symptoms and headache.

Prevalence of Temporomandibular Joint Disorders in Outpatients at Al-Badar Dental College and Hospital and Its Relationship to Age, Gender, Occlusion and Psychological Factors

Background: Temporomandibular disorder (TMD) is a collective term that encompasses many clinical problems involving the masticatory muscles, temporomandibular joints (TMJ) and associated structures and it has high prevalence among populations. Aims and objectives: To determine the prevalence of TMD and its relationship to age, gender, occlusion and psychological factors and to evaluate which age group, gender, malocclusion parameters and psychological factors contribute to the prevalence of TMD. Materials and methods: The study includes a sample of 250 young adults (134 girls and 116 boys) with age ranging from 18 to 25 years, the presence and severity of TMD was determined using a self-administered anamnestic questionnaire composed of 10 questions regarding common TMD symptoms. Morphologic occlusion was evaluated according to Angle's classification (molar classes I, II, III) and to evaluate the psychological factors, The hospital anxiety and depression scale (HADS) developed by Zigmond and Snaith was used. Results: Data were computerized and the SPSS package (version 11.2) was used and nonparametric test of Chi-square for data analysis and unpaired t-test was also used for statistical data analysis. Anamnestic index (AI) showed that the percentage of women (5522%) had higher degree of TMD symptoms than compared with men (50.86%), comparing the age of men and women free TMD and with TMD, the statistical difference was not significant as (t = 1.35, p > 0.5), distribution of the cases among Angle's class I, II, III occlusion the difference was not statistically significant as (p > 0.5), the degree of anxiety and TMD degree among men and women patients, women had higher anxiety levels as compared to men and no statistical difference was found between the cases of men and women in the depression levels. Conclusion: Prevalence of TMD symptoms in our sample of 250 patients was high for women- Morphologic occlusion was not associated with the presence of TMD symptoms. By considering the psychological factors we found anxiety but not depression associated with TMD symptoms.

The incidence and prevalence of temporomandibular disorders and posterior open bite in patients receiving mandibular advancement device therapy for obstructive sleep apnea

This study aims to evaluate the incidence and prevalence of temporomandibular disorders (TMD) in patients receiving a mandibular advancement device (MAD) to treat obstructive sleep apnea using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). In addition, it also aims to assess the development of posterior open bite (POB). Data from 167 patients were evaluated at baseline, from 159 patients after 118 days (visit II), from 129 patients after 208 days (visit III), and from 85 patients after 413 days (visit IV). The presence of TMD symptoms was evaluated through a questionnaire. TMD signs were assessed using the RDC/TMD. Clinical evaluation assessed for the presence of POB. The prevalence of TMD was 33/167 (19.8 %) at baseline. After an initial decrease to 14.5 % on visit II, the prevalence increased to 19.4 % on visit III and finally demonstrated a decrease to 8.2 % on visit IV. The incidence of TMD was 10.6 % on visit II. This decreased on further visits and only two (1.9 %) patients developed TMD from visit III to visit IV. POB was found to develop with an average incidence of 6.1 % per visit. The prevalence of POB was 5.8 % on visit II, 9.4 % on visit III, and 17.9 % on visit IV. The use of MADs may lead to the development of TMD in a small number of patients. Nevertheless, these signs are most likely transient. Patients with pre-existing signs and symptoms of TMD do not experience significant exacerbation of those signs and symptoms with MAD use. Furthermore, these may actually decrease over time. POB was found to develop in 17.9 % of patients; however, only 28.6 % of these patients were aware of any bite changes.

Prevalence of symptoms indicative of temporomandibular disorders in adults: cross-sectional epidemiological investigations covering two decades

Objectives. The aims were (1) to study possible secular trends in the prevalence of temporomandibular disorder (TMD) symptoms in adults and (2) to analyse possible associations between TMD symptoms and background factors. Materials and methods. The investigation has a repeated cross-sectional design. Three independent, randomly selected samples of ∼100 individuals in the age groups of 20, 30, 40, 50, 60 and 70 years, a total of 1704 subjects, participated in the Jönköping studies in 1983, 1993 and 2003. All the subjects were evaluated using a questionnaire and a structured interview relating to the presence of TMD symptoms. Associations between symptoms and the Anamnestic Dysfunction Index (Ai) as dependent variables and each of the independent variables, age group, gender, reported bruxism, trauma (1983), self-perceived health impairment and the year of investigation were analysed in binary logistic regression models.Results. The prevalence of the separate symptoms, apart from for TMJ clicking, did not vary to any statistically significant degree between the different examination years. However, the prevalence of recurrent headache in 20-year-old subjects rose remarkably in 2003 and an increase in the Ai I and Ai II for the whole population was observed during the 20-year period. Reported bruxism, which increased during the study period, and self-perceived health impairment were associated with most of the TMD symptoms and the Ai. Conclusions. An increase in the prevalence of TMD symptoms expressed as Anamnestic Dysfunction Index I and II has been noted over a 20-year period.

Association of dietary habits with symptoms of temporomandibular disorders in Bangladeshi adolescents.

The prevalences of signs and symptoms of temporomandibular disorder (TMD) in Bangladeshi adolescents and their associations with intake of various hard food items were investigated. A group of 1200 randomly selected high school students aged 12-17 years from three communities (rural, semi-urban and urban) completed a questionnaire on dietary habits and presence of TMD symptoms and were examined clinically. In bivariate analysis, no significant relationship was observed between TMD symptoms and eating of hard foods. However, in logistic regression analysis, clicking showed a significant correlation with consumption of hard vegetable and fruits more than three times per week (P < 0.05). A statistically significant correlation was also observed between consumption of all hard food items (at least one item in each of the four categories of hard food) more than 12 times per week and pain in the temporomandibular joint (TMJ) (P < 0.05). A positive association was found between pain in the TMJ and older age (15-17 years) (P < 0.001). The prevalence of pain in the TMJ was significantly higher in males (P < 0.01). Prevalences of clicking and pain in the TMJ were significantly higher in subjects living in a rural area than in subjects living in an urban area (P < 0.01 and P < 0.01, respectively). Subjects having one or more decayed, missing and filled teeth (DMFT) showed significantly higher prevalences of clicking (P < 0.01) and restricted mouth opening (P < 0.01). The results suggest that prevalence of TMD symptoms are related to prolonged consumption of hard food items.
