Azithromycin as an adjunctive treatment of aggressive periodontitis: radiographic findings of a 12-month randomized clinical trial.

Purpose: To compare the 12-month radiographic outcomes following the use of azithromycin or placebo as adjuncts to non-surgical periodontal treatment of AgP.

Methods: 17 aggressive periodontitis (AgP) subjects 13-26 years old were randomly assigned to receive scaling and root planing (SRP) with systemic azithromycin or placebo. Standardized radiographs were taken at baseline and 12 months postoperatively.

Use of hydroxyapatite in tooth replantation radiographically followed up for 14 years: a case report.

A lateral incisor was replanted 4 h after trauma. The tooth subsequently developed external root resorption treated with calcium hydroxide initially and with a hydroxyapatite root filling subsequently. Radiographs of the replanted tooth were obtained to follow up the patient for 14 years.
