non-surgical therapy III Flashcards
limitations of subgingival mechanical therapy
- bacterial migration from root surfaces not accessed by instrumentation
- bacterial can colonize gingival epithelial cells and connective tissues
- bacteria can be pushed into the dentinal tubules that root planing opens
- apical migration from supragingival plaque/ other infected sites
3 main systemic host modulatory agents
