“…A contraction protocol will be used to induce fatigue. [ 7 ] MVC clenching the teeth will be performed to record the time until initial exhaustion of the masseter muscle (determined by EMG). The groups will then be submitted to the interventions and MVC will be performed a second time to record the time until initial exhaustion of the masseter muscle (determined by EMG).…”

Background:Orofacial pain encompasses painful conditions, such as temporomandibular disorder (TMD). Multidisciplinary health teams seek to control such musculoskeletal disorders to improve the quality and functional capacity of the muscles of mastication. The aim of the proposed study is to evaluate the effect of low-level laser therapy as a form of treatment for the prevention of initial fatigue of the muscles of mastication (masseter and anterior temporal muscles) as well as the recovery of these muscles after induced exhaustion (caused by isometric contraction) in young adults.Methods:The participants will be 78 healthy male and female volunteers between 18 and 34 years of age. The volunteers will be randomly allocated to a laser group (n = 26), sham group (n = 26), and control group (n = 26). All participants will be submitted to a clinical evaluation to record mandibular movements, bite force, muscle sensitivity to palpation, and initial muscle fatigue. Initial fatigue will be induced by isometric contraction of the jaws. Maximum voluntary contraction will be performed to record the time until initial exhaustion of the masseter muscle (determined by electromyography). The groups will then be submitted to the interventions: active laser therapy (wavelength: 780 nm; fluence: 134 J/cm2; power: 50 mW; irradiance: 1.675 W/cm2; exposure time: 80 seconds per point) on 3 points of the masseter and 1 point on the anterior temporal muscles on each side; sham laser (placebo effect); or no intervention (control). Maximum voluntary contraction will be performed again after the interventions to record the time until initial exhaustion of the masseter muscle (determined by electromyography). Differences in individual time until exhaustion between the pre- and postintervention evaluations will be measured to determine the effect of low-level laser therapy.Discussion:Although studies have been made with the use of low-level laser therapy in TMDs and on the effect of photobiomodulation on fatigue, this the first study to test this therapy in the prevention of fatigue in this region. The clinical relevance lies in the fact that longer dental procedures could take place if the patients are less prone to fatigue.

This article focusses on those aspects of patient centred care which are relevant to dentistry. Understanding motivating factors and patient expectations of treatment are fundamental in the provision of high quality care. Ensuring that patients have realistic expectations can be enhanced by providing good information and communicating well at all stages of treatmentfactors which also enhance the overall patient experience. A wide range of factors contribute to patient satisfaction with treatment, alongside meeting expectations and ensuring that the treatment experience is positive, but some of these factors are still not fully understood and more work is required to understand, for example, how patients' psychological traits may influence satisfaction. It is essential that clinicians consider these factors when providing care for their patients and this paper discusses current evidence relating to patient expectations, patient experience, effectiveness of treatment (primarily quality of life) and also those factors which may impact on patient satisfaction with treatment. Clinical relevance statement Patient centred care involves being proactive about getting patients involved in decision making and build good professional relationships with to enhance communication and trust. Brief objectives statement To discuss the relevant aspects of patient centred care to dentistry including patient expectations, patient experience, quality of life and also those factors which may impact on patient satisfaction with treatment.
