Abstract: Nonsurgical therapy for the control of periodontitis consists of sub-gingival debridement, with oral hygiene instructions. Sub-gingival debridement without oral hygiene measures results in a limited healing response. Instruction on oral hygiene in the absence of sub-gingival debridement results in a suboptimal response clinically. The basic approach to periodontal infection has always been the removal of supra & sub-gingival bacterial deposits by scaling & root planning. Certain other aids such as the irrigants which are used by home or professional methods are also there other than mouth washes and systemic antibiotics. Newer advancements such as the local drug delivery the vector system and the probiotics also help in improving the maintenance of the oral hygiene status.
