Deep Pits and Fissures on the Occlusal Surface Make Cleaning

Question

Deep pits and fissures on the occlusal surface make cleaning the tooth difficult.

Accepted Answer

While it may seem that deep pits,fissures,or holes in enamel make cleaning difficult,these structures have numerous beneficial aspects.By serving as spillways during mastication,pits and fissures enable food to pass around teeth.This action prevents food from being forced interproximally.Pits and fissures facilitate interdigitation of opposing cusps during grinding of food,which dissipates extreme occlusal forces.Along with these beneficial aspects,deep pits and fissures promote plaque retention.
