Abstract
OBJECTIVE: To determine the effect of filled and unfilled sealants on micro-leakage of class V
composite restoration.
METHODOLOGY: This in-vitro experimental study was performed at department of dental materials from
August 2018 to January 2019. Sample selection was performed through non probability convenience
sampling. Class V cavities were prepared on the buccal surfaces of sixty extracted teeth at the level of
cemento-enamel junction (CEJ), the coronal margins were facing towards enamel and gingival margins
were at dentine. Later, cavities were filled with an adhesive system and composite, followed by
polishing. Samples were randomly divided in to 3 groups according to surface sealants. Twenty teeth in
each group (Clinpro, GC coat and Control) and preserved in the incubator at 37°C with in airtight
containers that were filled with 10ml (5%) solution of Methylene blue dye. After 24 hours samples were
dissected longitudinally in bucco-lingual direction and evaluated under a stereo microscope. The data
were statistically analyzed by chi square test.
RESULTS: Association among all 3 groups at gingival level was found to be statistically significant with
p value of 0.001 and chi square value of 30.46. Furthermore, at coronal level micro leakage was found to
be statistically insignificant with p value of 0.619 and chi square value of 2.64.
CONCLUSION: Both surface sealants have shown effectiveness in reduction of micro-leakage. However,
Clinpro has presented with better reduction in micro-leakage than GC coat.
