Introduction The aim of this in vitro study was to assess and compare the effect of different intermediary bases on microleakage between tooth and a nanocomposite interface in Class II box cavities in primary teeth. Methods Standard Class II box cavities were prepared in 52 primary molars and randomly divided into 9 groups according to the intermediary base used (Multicore Flow, Fuji II LC, SDR, Smart Dentin Replacement, and Biodentine). All specimens were subjected to thermocycling and prepared for microleakage testing and evaluation. Results There was significant difference in the mean ranks

Abstract Purpose: In recent years, laser etching has emerged as an alternative to conventional acid etching for enamel surface pretreatment due to its drawbacks. This method can be used as a substitute for preparing pits and fissures before sealing. The study aims to compare the impact of laser etching and conventional etching on microleakage, shear, and microtensile bond strength of hydrophobic and hydrophilic pit and fissure sealants. Methodology: The present in vitro study was performed on 60 healthy premolars which were extracted for orthodontic purposes which was cleaned and disinfected.
