Abstract
BACKGROUND:
The
aim of this systematic review was to answer the focused question, "In
adults, is there any association between sleep bruxism (SB) and alcohol,
caffeine, tobacco, or drug abuse?"
TYPES OF STUDIES REVIEWED:
This
systematic review included studies in which the investigators assessed
SB diagnosis by using questionnaires, clinical assessment, or
polysomnography and evaluated its association with alcohol, caffeine,
tobacco, or drug abuse. The authors graded SB as possible, probable, or
definitive. The authors developed specific search strategies for Latin
American and Caribbean Health Sciences Literature, PsycINFO, PubMed,
ScienceDirect, and Web of Science. The authors searched the gray
literature by using Google Scholar and ProQuest. The authors evaluated
the methodological quality of the included studies by using the
Meta-Analysis of Statistics Assessment and Review Instrument.
RESULTS:
From
among 818 studies, the authors selected 7 for inclusion in which
samples ranged from 51 through 10,229 participants. SB was associated
highly with alcohol and tobacco use. In 1 study, the investigators noted
a positive and weak association for heavy coffee drinkers. The odds for
SB seem to increase almost 2 times for those who drank alcohol, almost
1.5 times for those who drank more than 8 cups of coffee per day, and
more than 2 times for those who were current smokers. The abuse of
methylenedioxymethamphetamine associated with SB remained without
sufficient evidence.
CONCLUSIONS AND PRACTICAL IMPLICATIONS:
On
the basis of limited evidence, SB was associated positively with
alcohol, caffeine, and tobacco. The association between the studied
drugs could not be discredited; however, there is still a need for
stronger evidence based on studies with greater methodological rigor.
