Debridamento ultrass？nico de boca toda no tratamento da periodontite cr？nica: uma revis？o sistematizada

introduction: the full-mouth ultrasonic debridement seeks a more conservative instrumentation with light pressure of the root surface, preventing recolonization of periodontal pockets. objective: this study examined the effects of subgingival debridement through the use of ultrasonic devices on clinical periodontal parameters in the treatment of chronic periodontitis by a review of the literature. material and method: studies were selected on the bibliographic databases pubmed, lilacs, scielo, medline and the central registry of controlled trials (the cochrane library). it was included english language publications with clinical studies of human intervention, randomized controlled trials that used ultrasonic debridement for the nonsurgical treatment of chronic periodontitis. result: initially, we found 167 references and analyzing the titles and abstracts totaled ten studies the characteristics required and were considered valid for the completion of this review. studies have shown that the approach by ultrasonic debridement therapy may be favorable to the treatment of chronic periodontal disease. conclusion: it can be concluded that the treatment of chronic periodontitis by full mouth periodontal ultrasonic debridement produces similar outcomes to those achieved in conventional scaling and root planing.
