“…Children with a history of restless sleep present a 2. between emotional factors and the etiology of this habit. The presence of emotional stress 5,24 was affirmed to show a greater influence on bruxism compared with other factors, 25 including occlusal factors. It is worth emphasizing that a simple occlusal correction is not indicated as therapy for bruxism as instituting coadjutant therapies is necessary.…”

Association of infantile bruxism and the terminal relationships of the primary second molars Abstract: The aim of this study was to analyze the association between infantile bruxism and the terminal relationships of the primary second molars. A total of 937 pre-school children (both genders), aged from 2 to 6 years, from municipal schools in São Paulo were evaluated. In this study, a questionnaire considering the bruxism habit and the presence of headaches and/or restless sleep was answered by the parents/guardians. A clinical exam of occlusion in the anteroposterior direction (vertical plane -VP, mesial step -MS and distal step -DS) was performed by the examiners in the school environment. Student's t test, Fisher's test and a logistic regression test were applied for the statistical analysis at a significance level of 5%. The prevalence of the bruxism habit was 29.3% among the total sample. Because there was no significant difference between the sides evaluated, the left side was taken as the standard. Among those children with bruxism, 25.7% presented a mesial step terminal relationship at the primary second molars, 29.1% had DS, and 30.2% had VP. Regarding the association of the parafunctional habit with the type of terminal relationship, no significant results were found. Children who slept restlessly or suffered from headaches were verified to show a higher chance of expressing the habit (OR = 2.4 and 1.6, respectively). The prevalence of bruxism in the studied sample was 29.3%, and its association with the primary second molars' terminal relationship was not statistically significant.

Association between sleep bruxism and stress sensitivity in an experimental psychological stress task

et al. 2011

The objective of this study was to examine the association between sleep bruxism and psychological stress. The subjects consisted of 76 volunteers, who were divided into those with and without bruxism according to the diagnostic criteria for sleep bruxism outlined by the American Academy of Sleep Medicine (AASM). Stress sensitivity was evaluated before and after an experimental stress task, which involved simple mathematical calculations. It was assessed objectively by measuring the subjects' salivary chromogranin A (CgA) levels and subjectively using a ten-division visual analog scale (VAS). Compared with those observed before the stress task, the mean salivary CgA levels of the non-bruxism group (n = 54) were not significantly increased after the stress task. Conversely, the mean salivary CgA levels of the bruxism group (n = 22) were significantly increased after the stress task (P < 0.01). The mean VAS scores of the groups without (n = 54) and with (n = 22) bruxism were significantly (P < 0.01) increased after the stress task compared with those observed before the stress task, but no differences were detected between the two groups in the stress task. These findings suggest that there is an association between sleep bruxism and psychological stress sensitivity.Oral habits such as bruxism are thought to affect temporomandibular disorders (TMD) and might have a relatively strong effect on the durability of prosthetic appliances (20,30). Bruxism, which is defined as clenching or grinding of the teeth, or a combination of both, is a diurnal or nocturnal parafunctional activity and has long been regarded as requiring treatment (5). It is thought that bruxism is associated with psychological stress (1,2,8,10,22). On the other hand, some studies did not find any association between bruxism and stress (15,19). The following reasons might explain this disagreement. In most of the above studies, diurnal bruxism and sleep bruxism were not distinguished from each other, and there were variations in the methods used to evaluate oral habits. In addition, differing definitions of stress and various methods for assessing stress were employed in these studies (17). Also, in these studies, stress was evaluated subjectively, such as by self-reporting, questionnaires, etc. Thus, the relationship between bruxism and stress is much more complex than previously imagined and involves many psychosocial factors (17). When humans are exposed to psychological stressors, the hypothalamic-pituitary-adrenal (HPA) axis and the sympathoadrenal medullary (SAM) system are activated (9,13,26). This results in changes of biomarkers, e.g., cortisol and/or chromogranin, etc., being secreted into the serum or saliva. Therefore, stress can be objectively evaluated by analyz-

“…Similar results were found by Troman e Woods, (17) on the teaching career of teachers in the United Kingdom, where there is a trend of abandonment of the teaching profession caused by stress. Just like Vandera, (18) affirms in a study that there is a correlation between emotional stress and bruxism. In the research of Martins, (19) the majority of respondents who presented a severe degree of dysfunction and bruxism, considered themselves nervous or tense.…”

Introduction: Bruxism is characterized by the parafunctional act of tightening or grinding the teeth, which may occur in a conscious or unconscious way, during sleep or in wakefulness. It has become a growing concern in recent years due to its negative impact on quality of life (QOL) and also because it is considered an important risk factor for temporomandibular disorders. Objective: This study aimed to evaluate the QOL related to bruxism in physiotherapy teachers from a private institution through a questionnaire and their perception for such parafunction. Method: A cross-sectional, quantitative and exploratory study. The self-perception of bruxism was assessed through three questions from the Fonseca Anamnestic Indexand the perspective of QLV through the Quality of Life Questionnaire (SF-36), with a sample of 38 teachers of both genders. Results: Based on the results found, the level of statistical significance was set at p<0,05 for all tests. Among the 38 interviewees, 47,4% (n = 18) of professionals were observed with bruxism, with a higher prevalence in the female gender. Regarding the comparisons of QOL in relation to bruxism, a statistically significant difference was found in relation to the dimension of Pain (p=0,014), in which the mean for the bruxism group was (59,8) and without bruxism (78,5). Conclusion: There is a relation of the bruxism with the quality of life of the interviewees, and this habit mainly interferes in the domain of pain. Another aspect that was shown to be significantly associated with bruxism was nervous tension, in which the tense and nervous professionals were associated with self-perception of bruxism.
