Summary

Bruxism is a parafunctional habit characterized by grinding and/or clenching of the teeth. It may happen while awake (awake bruxism) or while sleeping (sleep bruxism). In adults, the prevalence is 20% for the awake bruxism and 8% for the sleep bruxism. Peripheral, central, and psychosocial factors influence the disorder, which may predispose to pain in the masticatory muscles and neck, headache, decreased pain thresholds in the masticatory and cervical muscles, limitation mandibular opening, sleep disorders, stress, anxiety, depression, and overall impairment of oral health. The aim of this study is to compare physical therapy interventions with dental treatment in pain, mandibular opening, sleep quality, anxiety, stress, depression, and oral health in individuals with bruxism.

Detailed description

Participants will be randomized into one of four groups: Group 1 (n = 24) intervention will consist of massage and stretching exercises; Group 2 (n = 24) will consist of relaxation and imagination therapies; Group 3 (n = 24) will receive dental treatment and Group 4 (n=24) will consist of massage, exercises, relaxation and imagination. The evaluations will be performed at baseline, immediately after treatment, and at 2-month follow-up. Pain intensity will be assessed using the visual analogical scale, while pain thresholds will be determined using algometry. Mandibular opening will be assessed using digital pachymeter. Sleep quality will be assessed by the Pittsburgh Sleep Quality Index, anxiety by the State-Trait Anxiety Inventory, stress by the Perceived Stress Scale-10, depression by the Beck Depression Inventory, and oral health will be assessed using the Oral Health Impact Profile - 14. Significance level will be determined at the 5% level. Valid Reasons of updates: 2014 - Changes made according requeriments of plattform of ClinicalTrials. 2015 - In 2014, in my qualification examination at University of São Paulo, the professors suggested my transfer from master degree to direct doctorate and the inclusion of more one intervention group, whereas the other three groups were still in the randomization process. I updated the registration in 2015 with the inclusion of this fourth group. However, as the protocol published in 2014 reports 3 groups (initial idea of the master degree before the transition to the direct doctorate), this fourth group started the treatment (massage, exercises, relaxation and imagination) after the end of treatment of other three groups (Groups:1,2 and 3). 2016- Although I have listed as primary variables: pain (VAS) and mandibular opening in this platform in 2013, and in the protocol published in 2014 (http://trialsjournal.biomedcentral.com/articles/10.1186/1745-6215-15 -8); symptoms like clenching, headaches and sleep difficulties were also assessed by VAS, and no included posteriorly to trial registration. They were evaluated, but not described in this platform. The same happened with intention to treat analysis. June 20, 2016- Updates for clarifications and suggested by the PRS Team. Please, any doubts, send me a e-mail! Thank you!

Conditions

• Bruxism

Interventions

Type	Name	Description
OTHER	Massage and stretching exercises	The routine to be used in this group (stretching, massage, and diaphragmatic breathing).
OTHER	Relaxation and imagination therapies	The routines to be adopted will focus on progressive muscle relaxation associated to imagination and diaphragmatic breathing.
OTHER	Dental treatment	Restoring treatment will involve direct reconstruction of the anterior guides (incisive faces of the incisive and canine teeth) with resin.
OTHER	Massage, exercises, relaxation and imagination therapies	The routine to be used in this group (stretching, massage, diaphragmatic breathing, progressive muscle relaxation and imagination therapies).
