RESUMEN
Bruxism is a sleep disorder characterized by grinding and biting teeth with multifactorial etiology, resulting in deleterious effects on teeth, periodontium, and temporomandibular joint. There is a lack of scientific evidence evaluating the effectiveness of medicines in treating this parafunction. The present case report was drafted under the rules of CARE checklist. An 8-year-old male patient with sleep bruxism and associated symptoms received a combined homeopathic therapy of Phytolacca decandra 12c and Melissa officinalis 12c for 2 months. After this period of combined homeopathic therapy, the bruxism and associated symptoms completely disappeared. After 2 years of clinical follow-ups, the patient had no recurrences. The use of homeopathic therapy was successful and should be seen as an alternative to treat sleep bruxism and its associated symptoms in children.
