After mechanical and chemical treatment root surface morphology by Scanning Electron Microscope

Three sources of mixed results. The ingredients may include calculus , cementum , dentin or dental cuticle . Many studies have shown that simple mechanical preparation,[link widoczny dla zalogowanych], including scaling ,[link widoczny dla zalogowanych], washing , soft bristled toothbrush scrubbing , ultrasonic cleaning,[link widoczny dla zalogowanych], treatment can not completely remove it. This study demonstrated that , whether it is closed scaling . Or for in vitro scaling and washing , the root surface were contaminated layer exists. Not only that , 3% hydrogen peroxide treatment has no obvious effect , that is,[link widoczny dla zalogowanych], 3% hydrogen peroxide can not remove the root surface contamination layer. And now proved the existence of pollution can interfere with another layer of adhesion formation. Auxiliary by citrate in the root surface after acid treatment shows better cleaning effect of pollution layers . In the inset on Figure 4 shows three clean surface structure of cementum . Sharp few remaining fibers and fiber bundles . High magnification of the image see a base exposure of collagen fibers . Proof of the citric acid treatment with pHl root surface . Can effectively clean the root surface ,[link widoczny dla zalogowanych], induced by exposure of collagen fibers , promoting the formation of re- attachment .
