Comparison of a sonic and a manual toothbrush for efficacy in supragingival plaque removal and reduction of gingivitis.

A new sonic electric toothbrush (Sonicare) and a traditional manual toothbrush were compared for efficacy in removing supragingival plaque and reducing gingival inflammation in a 12-week, single-blind clinical trial. 60 subjects with a gingival index (GI) of > 1.5 and no probing depths > 5 mm were randomly assigned to use either the manual or sonic brush, instructed in its use, and asked to brush each morning and evening for 2 minutes.

Guided bone regeneration around an immediate transmucosal implant for single tooth replacement: a case report.

This case report describes the procedure of guided bone regeneration around an endosseous dental implant, placed into an extraction alveolus in the absence of total soft tissue coverage, ie, in a transmucosal condition. The technique presented permits an immediate placement of the implant after the extraction of the maxillary right lateral incisor. A nonresorbable barrier membrane was used, and strict chemical plaque control was maintained during osseointegration.
