Background and Aim: Recently, the use of self – etch primers, due to their ease of manipulation, for fissure sealant therapy is recommended. The aim of this study was to compare the microleakage of Helioseal F using two methods.
Materials and Methods: In this in vitro study, 36 extracted intact human premolar teeth were randomly divided into two groups (n = 18) and were sealed with two methods: 1 – Conventional etching method. 2 – Using Prompt – Lpop acidic primer. All specimens were thermocycled for 1000 cycles at 5C – 55 C, then the teeth were immersed in 2% fuschin solution for 24 hours, sectioned and analyzed by stereomicroscopy. Data were subjected to Mann – Whitney test.
Results:There was no statistically significant difference in microleakage of sealants between two methods(P= 0.869).
Conclusion: In case of poor patient cooperation along with proper isolation, the use of self – etch primers is recommended for fissure sealant therapy.
