clinical conditions affecting the muscles of mastication, the temporomandibular joint (TMJ) and associated structures, resulting from a series of alterations of the masticatory system. The main symptom is pain, localized in the area of the masticatory muscles and/or in the preauricular area with a prevalence of 31.1% for adults and 11.3% for children.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">1</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">The etiology is multifactorial (parafunctions, clenching of teeth, stress, etc.) and continuous pain is frequently associated with comorbid pathologies such as anxiety, depression and insomnia, with patients sometimes presenting different degrees of moderate to severe depression.<a class="elsevierStyleCrossRef" href="#bib0060"><span class="elsevierStyleSup">2</span></a> It is known that both chronic pain and depression share common neurochemical substrates and similar dysfunctional alterations, and drugs that regulate pain by interrupting or reducing the release of neurotransmitters in the synapse between first and second order neurons are targets for their treatment. These situations could explain the role of serotonin reuptake inhibitors (SRIs) and tricyclic antidepressants (TCAs) in pain control and release.<a class="elsevierStyleCrossRef" href="#bib0065"><span class="elsevierStyleSup">3</span></a></p><p id="par0015" class="elsevierStylePara elsevierViewall">Although the use of TCAs as the treatment of choice for depression has been decreasing and more tolerable drugs, such as SSRIs, have been introduced, many clinicians use amitriptyline or its metabolite nortriptyline, at low doses, as first-line treatment for persistent myofascial pain (PMP), as it decreases both pain intensity and muscle tenderness.<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">4</span></a></p><p id="par0020" class="elsevierStylePara elsevierViewall">There are few studies that analyze the efficacy of TCAs and ISRs in the treatment of chronic orofacial pain (COP) in TMDs.

Pain intensity was assessed at baseline and at 3, 6 and 9 weeks using the visual analog scale (VAS). The sample size was calculated by repeated measures ANOVA, with 3 groups and 4 measurement times, with a power of 80% and a significance level of 0.05.
