Abstract:
Since the 1970s, root planing has become the core of non-surgical treatment of periodontitis to eliminate “infected cementum”. Subsequent studies on root endotoxin have concluded that excessive removal of the cementum by root planing is unnecessary, which also prompt the concept of “subgingival debridement”. At present, the mainstream view of standardized periodontal treatment still emphasizes the use of manual instruments to make the root surface biocompatible as an important procedure for removing the pathogens after subgingival debridement. Previous studies on root planing mainly focused on the comparison of ultrasonic subgingival debridement with manual subgingival scaling and root planing. Ultrasonic subgingival debridement has yet to be compared with ultrasonic subgingival debridement combined with manual root planing. This article reviews previous studies on subgingival debridement and root planing to provide guidance of decision-making for clinicians and references for future clinical research.
