The Relationship

Beginning with its founding at the start of this century by Edward H. Angle, the orthodontic profession's primary concern for its first forty years was the relationship of teeth. Orthodontists' efforts were directed towards how the teeth interdigitated. Since the early 1940's, due to the influence of Doctors Tweed, Brodie, Steiner, Margolis, etc., emphasis has been placed upon the effects of orthodontics on the patient's profile, and the profession was then concerned with both esthetics and tooth function. There are two final areas into which the bulk of the orthodontic profession has yet to move, and they are the areas of the temporomandibular joint myofunctional therapy. Orthodontists must now begin to incorporate TMJ function and the results of myofunctional therapy into their thinking and into their treatment plans and realize the effect they have upon improving the skeletal muscle, neurology and physiology of the patient's face as well as his facial esthetics and the cuspal interdigitation of his teeth. The dental profession as a whole must not only realize the role myofunctional therapy has in attaining these goals, but the role it plays in maintaining their subsequent stability.

Abstract Objectives Occupational stress is defined as a lack of coordination between job requirements and individual abilities. This stress relates to several salivary biomarkers. Stress plays an important role in creating temporomandibular disorder (TMD). In this study we aimed to investigate the relationship between stress and TMD by examining the occupational stress using dental environment stress (DES) questionnaire and measuring the stress markers in saliva including cortisol and immunoglobulin A in fourth to sixth year students of Qom Dental School. Methods In present study, 60 students participated. At first, a clinical examination was performed based on the RDC/TMD method to determine the temporomandibular joint status, then a DES questionnaire was completed to determine the occupational stress level and finally a sample of saliva was taken from the students and the amounts of salivary cortisol and IgA were measured by enzyme-linked immunosorbent assay (ELISA). Results The mean cortisol and IgA levels were 4.74 ± 2.80 ng/ml and 220.26 ± 121.22 µg/ml, respectively and the mean score of the DES questionnaire was 2.48 ± 0.58. In this study, 24 patients (40%) suffered from TMD. There was no correlation between cortisol and IgA levels with the DES score (p value > 0.05). There was no significant relationship between TMD and three variables of cortisol, IgA and DES scores (p value > 0.05). Conclusion Stress is one of the most important causes of TMD. Salivary biomarkers can be useful markers for determining stress in people with TMD but this issue was not confirmed in our study. Clinical relevance: In this study, no relationship was observed between TMD and occupational stress.

Abstract Background Patients with temporomandibular joint disorder (TMD) often complain of pain in other areas. Several studies have been conducted on spinal pain in TMD patients, but have contained only limited information. Therefore, this study analyzed the relationship between TMD and spinal pain in greater detail by using nationwide data. Methods A total of 12,375 TMD patients from the Korean National Health Insurance Review and Assessment database were analyzed. Controls were selected using propensity score-matching. The McNemar test, chi-square test, and paired t-test were used to compare the prevalence and severity of spinal pain between cases and matched controls. Logistic regression and linear regression models were used to analyze factors affecting the prevalence and severity of spinal pain in patients with TMD. Results The annual period prevalence of TMD was 1.1%. The prevalence was higher in younger individuals than in individuals of other ages and was higher in women than in men. The medical expenditure for TMD per person was $86. Among TMD patients, 2.5% underwent surgical procedures and 0.3% were hospitalized. The prevalence of spinal pain in patients with TMD was 48%, whereas that in the control group was 34%. Increased severity of TMD was associated with an increased probability of spinal pain. The medical expenditure, mean number of visits, and lengths of treatment for spinal pain were greater for patients with TMD than for controls ($136 vs. $81, 4.8 days vs. 2.7 days, 5.5 days vs. 3.3 days). Higher TMD grade was associated with greater differences in average medical expenditure, number of visits, and lengths of treatment for spinal pain between cases and controls. Additionally, for women, living in a rural area and having an older age and more severe TMD were associated with a greater probability of spinal pain and higher medical expenditure related to spinal pain. Conclusion A strong association was observed between the presence of TMD and the presence of spinal pain. The association became stronger as the severity of TMD increased, indicating a positive correlation between the severity of TMD and spinal pain.
