A matrix is a metal or plastic strip used to replace the missing interproximal wall of a tooth during the placement of the restorative dental material.
<h3> But now, scientists are trying out sealing interproximal incipient caries.</h3><h3>False or True.</h3>
At first, they were worried that sealants would keep germs in the pit and cause caries to spread. Dental sealants are typically applied on the chewing (occlusal) surface of the posterior permanent teeth, such as the molars and premolars, to help protect them against caries. However, researchers are also experimenting with sealing interproximal incipient caries. This is due to the molars' and premolars' chewing surfaces' grooves, which make them susceptible to tooth decay. Cleaning in these locations can be challenging due to the depth of these depressions.
In these grooves, bacterial plaque accumulates, and the acid produced by the bacteria from this enamel demineralization plaque causes caries. Fluoride helps to protect dental decay surfaces and sealants, fill the grooves, and prevent tooth decay by preventing food from getting stuck there.
