Clinical features of atypical odontalgia; three cases and literature reviews

BACKGROUND Atypical odontalgia (AO) is a disease characterized by continuous pain affecting the teeth or tooth sockets after extraction in the absence of any identifiable cause on clinical or radiographic examination. Antidepressants, such as amitriptyline, are reported to be effective in the treatment of AO; however, their efficacy varies depending on the case. In this article, we report three types of AO and discuss its heterogeneity and management. CASE PRESENTATION In the first case, a 58-year-old woman presented with a heavy, splitting pain in the four maxillary front post-crown teeth, as if they were being pressed from the side. Her symptoms abated with 20 mg of amitriptyline. In the second case, a 39-year-old woman presented with a feeling of heaviness pain on the right side of maxillary and mandibular molar teeth, face, whole palate, and throat. She was unable to function because of her pain. Her symptoms drastically subsided with 3 mg of aripiprazole. In the third case, a 54-year-old woman presented with a tingling sensation on the left mandibular second premolar and first molar, and an uncomfortable feeling on her provisional prosthesis that made it unbearable to keep the caps on. Her symptoms diminished with 2 mg of aripiprazole added to 30 mg of mirtazapine. CONCLUSIONS AO shows various features and responses to drugs. It is considered not only a purely sensory problem, but also a considerably complex psychological problem, such as rumination about the pain. Investigating the difference in pharmacotherapeutic responses might help to advance the treatment of AO.
