Prevalência e fatores associados ao bruxismo do sono em adolescentes de Teresina, Piauí

Abstract

SB is a frequent condition in adolescents, and the factors associated with its prevalence were: male sex, snoring and difficulty falling asleep.

Correlation between Parental-Reported Tooth Grinding and Sleep Disorders: Investigation in a Cohort of 741 Consecutive Children

“…Interestingly, nocturnal breathing symptoms that were under investigation in this work showed a correlation with parental-reported tooth grinding (sleep breathing difficulties, sleep apnea, and snoring). These results are consistent with literature knowledge, which suggested an association with snoring in children [ 7 ]. Guo et al included snoring among the risk factors related to the presence of bruxism [ 6 ], as also shown by another investigation that reported a relationship with respiratory disorders during sleep [ 19 ].…”

“…For instance, a correlation between parental-reported tooth grinding and bedtime problems, such as sudden movements while falling asleep ( r = 0.234), restless legs movements, muscular pain or tingling, and falling asleep sweating, has emerged. According to Santos-Suosa et al, SB in individuals with difficulty in sleeping may be a possible result of a nervous system excitation response accompanied by body movements [ 7 ]. Furthermore, Goncalves et al in a cross-sectional study reported an association between SB and problems with falling asleep, with an OR of 4.1 [ 18 ].…”

“…Also, Bortoletto et al asserted that children with SB have a greater risk of having primary headache [ 25 ]. According to some authors, patients with SB generally have morning headaches, which may depend on repetitive muscle contractions leading to tension headache [ 7 ]. On the other hand, in a case-control study of Bruni and colleagues, nocturnal symptoms were more frequent in migraine patients, especially breathing difficulties, snoring, sleep apnea, sleep talking, bruxism, and reports of frightening dreams, while tension-type headache patients were not different from controls [ 26 ].…”

“…In two systematic reviews, Guo et al listed the many factors that have been described in association with SB in children [ 5 , 6 ]. Some studies assessed the relationship between parental-reported SB and sleep disorders (e.g., bedtime problems, night awakening, nocturnal symptoms, nocturnal breathing symptoms, and morning symptoms) [ 7 , 8 ], whilst some others investigated for the association with behavioral problems, such as hyperactivity, poor school performance, and attention deficit. A large investigation by Restrepo et al suggested that some sleep disorders are associated with parental-reported tooth grinding, even if further studies are needed to refine findings [ 9 , 10 ].…”

The Relationship between Sleep Bruxism and Obstructive Sleep Apnea Based on Polysomnographic Findings

“…However, no such correlation was observed in patients with a severe form of OSA (AHI ≥ 30). One of the hypotheses linking SB and OSA is that SB activity protects against OSA by protruding the mandible and restoring airway patency [20,21]. However, this mechanism may not be adequate to prevent the airway from collapsing in severe OSA.…”
