Methods: Sixty periodontally involved human extracted teeth were randomly assigned to six groups: G1-SRP alone (control); G2- topical application of CarisolvTM + SRP; G3- burnishing application of CarisolvTM + SRP; G4- multiple applications of CarisolvTM + SRP; G5- SRP + 24% EDTA gel; G6- topical application of CarisolvTM + SRP + 24% EDTA gel. The chemical gel was applied to each root surface for 30 seconds, followed by 50 strokes that were performed during scaling and root planing, except in group 4. In this group, multiple gel applications were interposed with mechanical instrumentation of the root surfaces, which were instrumented until a smooth, hard and glass-like surface was achieved. In groups 5 and 6, the 24% EDTA gel was burnished onto the root surface for 2 minutes. Following each treatment, the teeth were sectioned to obtain experimental specimens. All specimens were analyzed by SEM. Statistical analysis was performed using Newman-Keuls test. Results: There was a statistically significant difference in the root surface morphology only when G1 was compared to G3, G5 and G6 (p<0.05). Smear layer was evident in both control (G1) and chemo-mechanical treatment specimens (G2, G3 and G4), with no statistically significant difference between the treatment modalities (p>0.05). Multiple gel applications (G4), however, were more effective in removing the smear layer than G2 or G3 treatments (p<0.05). Conclusion: These findings suggested that the CarisolvTM application have a significant effect on the alteration of root surface morphology, only when it was applied using the burnishing technique. Smear layer removal can be improved by multiple applications technique used in the present study. | ||
