Objective.-To investigate the relationship between the frequency of sleep bruxism and report of morning headaches, and associations with depression and/or anxiety.Background. -The association between sleep bruxism and headaches in the morning, and between these factors and affective disorders, has been examined in several investigations. Although headache is cited by the International Classification of Sleep Disorders as a symptom associated with sleep bruxism, only a small number of studies have investigated the association between the frequencies of headaches in the morning and bruxism.Methods.-This was a cross-sectional observational study conducted between August 2017 and May 2018 in the municipality of Curitiba, Brazil. It comprised individuals of both sexes, ages between 18 and 65 years, with no restriction of race, skin color, or social group (n = 149). Structured questionnaires were used to survey demographic characteristics, sleep bruxism, depression, and anxiety. Self-reports and clinical examinations were used together to diagnose probable sleep bruxism and assess the frequency of this condition. The presence or absence of morning headaches and their frequency were evaluated using a self-report question. It was applied to people with anxiety and/or depression and to free controls of the general population by a trained dentist.Results.-A significant relationship (P ˂ .001 -Chi-square test) was found between the frequency of sleep bruxism and morning headaches. Symptoms of depression and anxiety were associated with the presence of headache (P ˂ .001 -One way ANOVA), but not with the frequency of sleep bruxism.Conclusion.-The present study confirms the hypothesis of a direct relationship between the frequency of sleep bruxism and the frequency of morning headaches. It also confirmed a linear association between mean depression scores, mean anxiety scores, and morning headaches.
The aim of the study was to describe the efficacy of buspirone in controlling nonpharmacological awake and sleep bruxism.Methods: Four cases of nonpharmacological awake and sleep bruxism, one of them with a 20-year-long history, in which buspirone succeeded to control bruxism, are described and discussed.Results: Two of the 4 cases had sleep bruxism, and the other 2 cases had sleep and awake bruxism. Besides anxiety, no other predisposing condition was identified. Buspirone was effective in reducing bruxism symptoms in the 4 cases. Mean percentage of bruxism reduction after buspirone was ranked as 65% by subjects. Conclusions:In this small series of cases, buspirone proved effective in the control of nonpharmacological awake and sleep bruxism.
Professor Sérgio Mascarenhas was a Brazilian researcher with a vast legacy. His work paved the way for new research possibilities by consolidating the use of innovation and transdisciplinary science. In Medicine, he proposed changes to what had previously been well-accepted concepts, and his contributions have influenced medical practices. Although many authors consider intracranial pressure (ICP) as an unrivaled variable for monitoring and diagnosis of many diseases, its clinical applicability is still the subject of debate in the literature because of the difficulty in standardizing protocols. Mascarenhas's research and the creation of a device for noninvasive monitoring of intracranial compliance are discussed and are shown to have led to the creation of Brain4care, a start-up, and a new perspective on the debate on ICP monitoring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
