Photobiomodulation on trigeminal neuralgia: systematic review.

Trigeminal neuralgia is a recurrent episode of facial pain, that may be associated with other conditions such as multiple sclerosis, neoplasms, and nerve compromises or may occur due to an unknown cause. The available treatments are pharmacotherapy or surgery; however, both are susceptible to develop side effects. Photobiomodulation could be a promising alternative therapy for trigeminal neuralgia. A systematic review of literature was carried out using the PRISMA protocol, in the PubMed/MEDLINE, Embase, and Web of Science databases. Risk of bias by ROB 2.0 protocol was performed in included studies. Initially, 20 identified articles were collected varying between the years of 1983-2018, from which 6 were included. A total of 193 patients were evaluated; photobiomodulation was compared to conventional therapies, TENS, and therapy combinations with pharmacotherapy. The overall risk of bias was low, with some concerns in the randomization and double-blinding process; moreover, there are few reports in the literature. Photobiomodulation appears to be as effective as conventional therapies, being a coadjutant therapeutic opportunity for the treatment of trigeminal neuralgia.

Assimetria da face associada à mordida cruzada medida em radiografias panorâmicas / Asymmetry associated with the crossbite measured in panoramic radiographs

A mordida cruzada posterior (MCP) é uma relação anormal vestibulo-lingual dos dentes posteriores quando em oclusão. E uma má-oclusão frenqüente, que pode causar assimetria na face do paciente quando não tratada precocemente. Esta pesquisa utilizou radiografias panorâmicas para comparar as medidas da altura do ramo (Rh) e do côndilo (CH), de pacientes portadores de MCP com os sem esta alteração, onde concluímos que ocorreu prevalência de assimetria mandibular em pacientes de MCP, em maior proporção na CH
