ABSTRACT
The aim of this study was to assess the effects of sleep hygiene measures combined with relaxation techniques in the management of sleep bruxism (SB) in a double-blind, parallel, controlled, randomised clinical trial design. Sixteen participants (mean ± s.d. age = 39·9 ± 10·8 years) were randomly assigned to a control group (n = 8) or to the experimental treatment group (n = 8). Participants belonging to the latter group were instructed to perform sleep hygiene measures and progressive muscle relaxation techniques for a 4-week period. Two polysomnographic recordings, including bilateral masseter electromyographic activity, were made one prior to the treatment and the other after the treatment period. The number of bruxism episodes per hour, the number of burst per hour and the bruxism time index (i.e. the percentage of total sleep time spent bruxing) were established as outcome variables. No significant differences could be observed between the outcome measures obtained before and after the 4-week period, neither for the sleep bruxism variables nor for the sleep variables. Within the limitations of this study, it was concluded that there is no effect of sleep hygiene measures together with progressive relaxation techniques on sleep bruxism or sleep over a 4-week observation period.
