A Comparative Clinical Evaluation of Surgical Blade Abrasion and Partial Thickness Flap as Treatment Modalities for Gingival Pigmentation.
Objective: To compare the retention and marginal discoloration of Self-etch and Total Etch Adhesive
before Pit and Fissure Sealant application at 1 month, 3 months, 6 months, and 12 months. Materials and
methods: 30 school-going children received sealants in all four permanent second molars,this study was
carried out in the Department of Pedodontics and Preventive Dentistry. The fully erupted second
permanent molars were randomly allocated into 2 groups: group A (Self-Etch) and B (Total etch) .
According to the split-mouth design, each patient received sealant in the second molar with self-etch in
one arch and total-etch in the other arch; contra-lateral molars were kept in the control group. Results: No
statistically significant difference was found in the marginal discoloration and microleakage of fissure
sealants placed on occlusal surfaces following the use of a Self-Etch bonding agent and traditional Total-
Etch adhesive after 12 months. Conclusion: When TotalEtch adhesive is applied before sealant, the same
amount of microleakage or marginal discoloration happened in the occlusal fissure of permanent teeth as
when SelfEtchant adhesive was put on before sealant.
