Non-surgical therapy, including supra- and subgingival scaling and root planing is one of the most important means of treating periodontitis. The objective of subgingival instrumentation in periodontally diseased sites is to remove the adhering microbial biofilm and calcified deposits and to create a clinically smooth root surface in order to promote a healing response in the gingival tissues. However, total removal of calculus is a difficult task. Following debridement of the periodontally involved root surface, the thoroughness of calculus removal is traditionally evaluated using a periodontal probe. The main failure in periodontal treatment may depend on calculus remaining after therapy. Recently, a novel measurement device has been introduced. The DetectarTM-system is designed for objective subgingival calculus diagnosis. By evaluating the root surfaces with LED light and detecting differences between calculus and the root surface, the endpoint of root surface instrumentation might be assessed more precisely.
