Summary

Odontogenic sinusitis affects mucous membrane of the maxillary sinus and can be caused by the evolution of a tooth injury with formation of periapical abscess that advances into the sinus cavity. We present a patient with dens in dente in the upper right lateral incisor tooth, which suffered carious process and periapical abscess, contaminating the sinus mucosa on this side, which caused pain, bulging and tooth displacement. Surgery was performed via a CaldwellLuc access for curettage of the lesion, indicating the presence in the histopathological diagnosis of radicular cyst abscess and sinusitis. After 18 months of control, alveolar bone regeneration and spontaneous repositioning of teeth involved was observed. The authors warn that cingulum deep in dens in dente are diseases of the tooth that deserve attention for the diagnosis and prevention of carious processes in order to avoid further complications.

KEY WORDS: dens in dente, maxillary sinus, sinusitis.
