Using a Delphi panel to survey criteria for successful periodontal therapy in anterior teeth.

Abstract：

BACKGROUND:Valuable decision making for periodontal treatment success in situations where there is ambiguous or conflicting information was previously reported using a consensus building method, the Delphi survey, for posterior teeth with chronic periodontitis. This study focuses on outcome measures relevant in assessing therapy of anterior teeth with chronic periodontitis. METHODS:The Delphi panelists were the same American periodontists who participated in the previous Delphi survey evaluating successful therapy in posterior teeth. In this study, panelists determined the level of importance of attachment level, probing depth, mobility, plaque, inflammation, esthetics, pain, and patient satisfaction following periodontal treatment of a single tooth or multiple anterior teeth in a patient with severe chronic periodontitis. The panelists were questioned concerning the relative importance of each outcome measure, a minimally acceptable level considered necessary for success for each outcome measure, and the length of time required for these outcome measures to remain stable. RESULTS:The 35 panelists considered the control of pain, esthetics, and patient satisfaction to be "extremely important" outcome measures for successful periodontal treatment of single or multiple teeth. Attachment levels, probing depths, plaque levels, degree of inflammation, and mobility (for multiple teeth) were considered to be "very important" outcomes. The minimally acceptable reduction in probing depths following 1 year of treatment was 2 mm; whereas 2 mm of attachment gain was considered necessary for successful treatment. The panel also found a Miller degree I mobility as an acceptable outcome for clinical success. Finally, the panel agreed that the 1-year results of treatment should remain stable for a minimum of 5 years. CONCLUSIONS:The Delphi technique proved a practical instrument to transform expert opinion into a group consensus for relevant periodontal outcome measures. Absence of pain, esthetics, and patient satisfaction were outcome measures considered "extremely important" for successful therapy. Although panelists considered attachment loss, probing depths, and mobility somewhat less important outcomes, they wanted an attachment gain of 2 mm and would accept a degree I mobility as long as outcomes remained stable for 5 years. These data suggest that minimal standards for successful therapy of anterior teeth can be established among periodontal practitioners.
