What is the reason the mandibular first molar retained sealants better than maxillary?


Answer:
because maxillary is working against gravity while the mandibular is always being pushed in from the weight of your entire cranium being supported by your mandibular teeth
Could just be a difference in the pits and fissures. Could be the way your bite occludes. Could be a number of things.
Deeper grooves possibly, if you chew ice or anything hard like that it can chip sealants off. If you eat anything sticky like taffy/carmel it can pull them off, grind teeth can knock them off, when the sealants are placed they put a cleaner to clean out the pores and grooves of teeth so the sealant will stick good sometimes certain teeth get cleaned better than others, If at anytime during sealants water/saliva gets on the tooth it weakens the bond of sealant to tooth and it will come off. General wear b/c of bite. Generally they stay on 1-3 years sometimes longer if really successful (this usually depends on age when placed). Sealants placed on 6 years olds usually don't hold as long as those placed on 16 year olds b/c they can hold stiller and are more cooperative.
