Objective: To analyze the literature about AO, as well as its epidemiology, pathophysiology, predisposing factors, associated pathologies and treatment.

Methodology: Information was searched in PubMed, SCOPUS and Google Scholar. Key words were used to search for information such as: atypical odontology, epidemiology, pathophysiology, related disease, treatment, among other relevant articles.

Results: AO occurs in women (85%) and men (20%) between 50 - 60 years old, hormonal or psychiatric disorders, related to local neuropathies due to problems in electrical conduction, and present or largely confused with trigeminal neuralgia and burning mouth syndrome mainly, sometimes it is possible to identify duct treatment or a history of aggressive therapy in the area, and can be treated with Amitriptyline, Imipramine, Aripiprazole, and locally with Botulinum Toxin A with favorable results found at 4 weeks.

Conclusion: AO does not have specific characteristic criteria for its diagnosis, leaving a wide spectrum of possibilities that represent a complex pathology that needs further study.
