Pathologic changes in soft tissues associated with asymptomatic impacted third molars.

Objective: The aim of this study was to examine the need for routine removal of asymptomatic impacted third molars under the prophylactic indication, based on the incidence of pathologic changes. The frequency and type of pathologic conditions associated with impacted third molars were also evaluated.

Study Design: One hundred twenty impacted third molar dental follicles were submitted for histopathologic examination.

An unusual association of odontomas with primary teeth.

Odontomas generally appear as small, solitary or multiple radio-opaque lesions found on routine radiographic examinations. Traditionally, odontomas have been classified as benign odontogenic tumors and are subdivided into complex or compound odontomas morphologically. Compound odontomas commonly occur in the incisor-canine region of the maxilla and complex odontomas are frequently located in the premolar and molar region of both jaws.

Routine antibiotic prophylaxis is not necessary during operations to remove third molars.

The purpose of this study was to evaluate the efficacy of antibiotic prophylaxis during removal of impacted third molars. We studied 150 patients with impacted mandibular or maxillary third molars who were divided randomly into three groups. The first was given amoxicillin 2g combined with clavulanic acid, orally daily for 5 days postoperatively; starting at the end of the operation.
