There is some debate about whether to bevel or not the cavosurface margins in the occlusal box of a class II preparation for resin restoration in a primary molar in order to remove the aprismatic enamel and increase the surface area for bonding.
hi mona, well there have been very few studies that have checked the effect of bevel on cavosurface margins of PRIMARY molars, heres is one of the classical in vivo clinical trial which might help you to understand the concept of beveling in primary teeth
hope it is helpful

Hai Mona, I think you should read the following article then you get an answer

Hi Mona, I would like to know first, why do you ask this question? On the benches of the dentistry school we taught us that the particular orientation of the enamel prisms in the primary molar is different from permanent molar and it makes useless the beveling because there are not steady prisms in the cavo-surface margins. However, I find the paper recommended by our colleagues Adit et Nirmala very interesting especially because the studies on the temporary teeth are relatively rare.
