Effects of Citrica Acid, Edta And Tetracycline Hydrochloride On Periodontally Involved Root Surface ( A SEM STUDY ).

Root debridement by scaling and root planing may not completely remove contaminated cementum particularly in more apical areas. The smear layer formed during root planing inhibits cell migration and attachment leading to impaired marginal periodontal healing. In the present study an attempt is made to compare the morphological effects of root surface demineralization using citric acid, TTC and EDTA as root conditioning agents. The findings obtained from this study could form the basis for future in vivo studies using the same agents for demineralization procedures.
