The effect of patient-centered plaque control and periodontal maintenance therapy on adverse outcomes of periodontitis.
The purpose of this study was to evaluate systematic reviews that addressed the effectiveness of periodontal maintenance therapy for the management of patients with periodontitis. Recent surveys of dental care patterns suggest a marked increase in preventive and maintenance periodontal care in populations that retain the dentition for an increasingly longer lifetime. A considerable body of clinical investigation concludes that a multitherapy periodontal maintenance approach is effective in improving periodontal outcomes in patients treated for periodontitis. Individual components of such maintenance therapy were assessed, including the effects of an oral examination, personal oral hygiene instructions, supragingival scaling and polishing, subgingival scaling and root planing, adjunctive procedures, and maintenance frequency. There is much controversy about improvement in oral health that may accrue from the placebo effect of an examination and the maintenance ritual. Improved plaque control by the patient in anticipation of a forthcoming examination alone might be reflected in decreased measurements for plaque accumulation and gingival inflammation but the role of placebo effects on periodontitis remains unclear. There are insufficient randomized controlled trials to reach conclusions regarding the individual beneficial effects of repeated oral hygiene instructions or routine scaling/polishing on the recurrence of periodontitis. While subgingival root planing seems an effective component of periodontal maintenance, neither clinical investigations nor randomly controlled trial evidence have established an ideal maintenance frequency based on individual patient risk for periodontitis. The adjunctive beneficial effects of both locally and systemically administered antimicrobial agents were statistically significant for some formulations, and may be particularly useful clinically in patients who are resistant to mechanical therapy. We conclude that few clinical or randomized controlled studies have evaluated the individual benefit or required frequency of the periodontal maintenance ritual for patients who are relatively resistant or susceptible to periodontitis.
