Association Between Oral Behaviors and Painful Temporomandibular Disorders: A Cross-Sectional Study in the General Population

Background

Studies have reported correlations between various oral behaviors and painful temporomandibular disorders (TMD), yet comprehensive research on the independent effects of each oral behavior within the general population remains sparse.

Objective

This cross-sectional study aimed to investigate the association between painful TMD (PT) and various oral behaviors in general population.

Methods

A questionnaire survey was conducted with participants to collect data encompassing demographic characteristics, eight specific oral behaviors, and the 5 major TMD symptoms(5Ts) checklist. Participants were categorized into PT and non-PT (NPT) groups based on their responses to the 5Ts checklist. Those reporting TMJ/facial pain or headaches were assigned to the PT group, while all other participants constituted the NPT group. Both univariate and multivariate logistic regression analyses were employed to evaluate the association between individual oral behavior and the presence of PT, controlling for demographic confounders including age, sex, systemic diseases, and dental treatments history.

Results

A total of 441 valid questionnaires were received, including 156 males and 285 females. The prevalence of PT was identified to be 33.33%, with 61.00% of participants engaging in one or more types of oral behaviors. Each oral behavior was more frequently reported in the PT group compared to the NPT group. The univariate logistic regression analysis identified positive correlations between all eight oral behaviors and PT. In the multivariate logistic regression analysis, these associations persisted after adjustment for demographic confounders including age, sex, history of systemic diseases and dental treatments (P<0.01). The behaviors most strongly associated with PT were "Hold or jut jaw forward/to the side" (OR:4.478), "Hold, tighten or tense muscles without clench" (OR:3.343) and "Hold jaw in rigid or tense position" (OR:3.209).

Conclusion

The presence of oral behaviors has significant association with PT. Individuals exhibiting multiple oral behaviors are more likely to experience PT. Additional studies are needed to clarify the effects of reducing oral behaviors on pain-related symptoms.

Associations Between Temporomandibular Pain and Biobehavioral Variables in Dental Students in Response to an External Stressor

AIMS

To assess changes in temporomandibular disorder (TMD) pain and multiple biobehavioral variables relevant to TMDs in response to an external stressor.

METHODS

Self-reported data using online DC/TMD questionnaires were collected from volunteer dentistry graduate students. Data collection was performed on two occasions: during a non-exam period of the semester and during the subsequent exam period. Changes in the proportion of students with pain, differences in pain grade, and severity of biobehavioral status were measured and compared over the two periods. The association between severity of non-exam-period biobehavioral status and pain presence was also tested to assess whether biobehavioral variables can predict pain occurrence or persistence. Chi-square test, Wilcoxon signed-rank test, ANOVA, and Kruskal-Wallis tests were used for data analysis. P < .05 was considered significant.

RESULTS

Of the 213 enrolled students, 102 remained after data reduction. In the non-exam period, the proportion of individuals with pain was 24.5%; in the exam period, the proportion was 54.9%, and more students had a higher pain grade. The severity of all biobehavioral variables was higher in the exam period, but there was no association between changes in the presence of pain and changes in biobehavioral variables. Higher anxiety and parafunction levels were found in those who reported pain on both occasions.

CONCLUSION

Exam periods initiate readily measurable changes in the psychologic status of many students, as well as alterations in their temporomandibular pain. Higher levels of anxiety and oral behaviors during non-exam periods seem to be predictors for persisting pain.

Psychosocial and Behavioral Factors in Awake Bruxism-Self-Report versus Ecological Momentary Assessment

The issue of psychosocial factors and concurrent conditions associated with AB is a relatively new approach in the study of Awake Bruxism (AB). In the present study a population of 84 dental students were assessed for probable AB with two modes of AB assessment: Single point self-report (SR) and ecological momentary assessment through a designated smartphone application (BA). The two assessment modes were compared with regard to their ability to phenotype subjects as far as the following psychosocial and behavioral variables are concerned: Gender; depression; somatization; oral behaviors; chronic pain and associated pain symptoms in the head, neck and scapula. Two-way ANOVA showed main effect of SR for the following variables: Chronic Pain Intensity score (F_(1,49) = 6.441, p < 0.02), migraine/headache (F_(1,81) = 7.396, p < 0.01), pain in neck (F_(1,81) = 6.726, p < 0.05), pain in scapula (F_(1,81) = 8.546, p < 0.005) and the oral behaviors of pushing the tongue forcefully against the teeth (F_(1,81) = 5.222, p < 0.05) and inserting the tongue between the upper and lower teeth (F_(1,81) = 5.344, p < 0.03). The effect of SR on the habit of chewing gum was borderline (F_(1,81) = 3.369, p = 0.07). Main effect of BA was found for depression (F_(1,81) = 6.049, p < 0.05), while the effect of BA on somatization was borderline (F_(1,81) = 3.657, p = 0.059). An interaction between SR and BA groups could be observed for the behavior of biting, chewing or playing with the tongue, cheeks or lips (F_(1,81) = 4.117, p < 0.05). The results suggest that a combination of a single-point self-report referring to the past 30 days, and an ecological momentary assessment supplying information about the actual timing of the report, can help us to better assess AB, as well as increase our ability to define the phenotype of subjects with AB as far as psychosocial and behavioral factors are concerned.

Smiling, Yawning, Jaw Functional Limitations and Oral Behaviors With Respect to General Health Status in Patients With Temporomandibular Disorder-Myofascial Pain With Referral

Background: The temporomandibular joint is the one of the most important joints in the human body. It enables numerous orofacial functions such as mastication, swallowing, breathing, speech, emotional communication, and facial expressions. The aim of the study was to evaluate the prevalence of jaw functional limitations and oral behaviors with respect to general health status in patients with temporomandibular joint disorders—myofascial pain with referral.

Materials and methods: The study group consisted of 50 individuals (37 females and 13 males) with complete natural dentition. The average age was 23.36 years with ± 0.30 as a standard error. All subjects underwent clinical examination and were diagnosed with myofascial pain with referral according to the Diagnostic Criteria for Temporomandibular Disorders. The survey was conducted in connection with the Jaw Functional Limitation Scale-8 (JFLS-8), Jaw Functional Limitation Scale-20 (JFLS-20), Patient Health Questionnaire-4 (PHQ-4), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-15 (PHQ-15), and Oral Behaviors Checklist (OBC).

Results: The most common functional problems in the entire study group were chewing tough food and yawning. In terms of gender, statistically significant differences were noted for chewing tough food and smiling (p = 0.015451; p = 0.035978, respectively). With respect to Bonferroni correction and Benjamini-Hochberg procedure, the observed differences were not statistically significant. There were no statistically considerable differences in mastication, mandibular mobility, verbal and emotional communication, or global limitations (p > 0.05). Over half (56%) of the respondents had depression of varying severity. Somatic symptoms of different severity were found in 78% of the patients, and 44% of the respondents declared anxiety disorders. The score of the Oral Behavior Checklist (OBC = 27.18) highlighted a high tendency for developing craniomandibular disorders.

Conclusion: Patients with myofascial pain with referral, demonstrated a disturbed biopsychosocial profile. The restrictions in yawning and smiling as well as limitations in mastication, mobility, verbal and emotional communication, and global limitations appear to be significant predictors of craniomandibular dysfunction. Depression, stress, and somatic disorders are important factors predisposing patients to the occurrence of myofascial pain with referral. The progression of oral behaviors may indicate the role of somatosensory amplification.

Oral health status, dental treatment needs, and barriers to dental care of elderly care home residents in Lodz, Poland

Objectives

To determine oral health status, dental treatment needs, and to identify barriers that prevent easy access to dental care by elderly care home residents in Lodz.

Background

Studies in many countries show that oral health status of elderly care home residents is poor and there is an urgent need to improve it.

Methods

The study included 259 care home residents, aged 65 years and older. The oral examination was performed. In face-to-face interviews, subjects were asked about frequency of cleaning teeth and/or dentures, whether they needed assistance, and whether the assistance was available; they were also asked about the perceived dental needs, and about the time since their last visit to a dentist and the purpose of the visit. If they had not visited the dentist in the past 12 months, they were asked about reasons for failing to visit the dentist.

Results

Forty-six percent of the subjects were edentulous. Only 5.8% of all participants had a sufficient number of functional natural teeth. Dental treatment was found to be necessary in 59.8% of the respondents. One in four subjects reported reduced ability of correctly cleaning teeth and dentures themselves, of whom only one-third were helped by others. An insufficient level of hygiene was found in every other subject. About 42% of residents had not visited a dentist for over 5 years, mainly due to organizational reasons.

Conclusion

Expanding the current scope of medical care for the elderly care home residents to include dental care would improve their currently poor oral health status.

Social gradients in dental health among low-income mothers and their young children

For low-income mothers of children aged 3-6 years, we estimate whether social gradients exist between mothers' income, education, and employment status and mothers' perceptions of self and child dental and general health, and whether these relationships differ by racial/ethnic group. Disproportionate stratified sampling by racial/ethnic group selected 10,909 eligible children aged 3 to 6 in Medicaid in Washington State. Mothers (n=4,373) completed a mixed-mode (web, mail, telephone) survey. Mothers' education had a strong, gradient relationship with mother ratings of self and child dental health that was not explained by other measures. Similar gradients were found for mothers' employment status and income, but some associations were no longer significant (p>.05) after adjusting for oral health beliefs and behaviors, dental insurance, and regular dental care. Associations did not differ significantly by racial/ethnic group.
