BACKGROUND Trigeminal neuralgia is accompanied by severe mechanical, thermal and chemical hypersensitivity of the orofacial area innervated by neurons of trigeminal ganglion (TG). We examined the role of the voltage-gated sodium channel subtype Nav1.9 in the development of trigeminal neuralgia. RESULTS We found that Nav1.9 is required for the development of both thermal and mechanical hyperse...

Diverse studies suggest that non-steroidal anti-inflammatory drugs (NSAIDs) induce antinociception through inhibition of cyclooxygenases. In this study was evaluated the effect of NSAIDs to induce antinociception either alone or in combination in the formalin orofacial test of rodent. Male mice were injected intraperitoneally with dexibuprofen, dexktoprofen, diclofenac meloxicam, metamizol, and...

OBJECTIVE To verify the frequency of self-reported medical conditions and pain areas in orofacial pain patients, comparing them with patients from the routine dental care. METHODS Data were collected from archives of the Orofacial Pain Clinic (Group A, n=319) and of the routine dental care clinics (Group B, n=84) at Faculdade de Odontologia de Araraquara, São Paulo, in Brazil. All individuals...
