Question

Quizplus · Accepted Answer

A laser caries detector cannot be used to diagnose interproximal caries because of limited access to interproximal surfaces.It cannot detect caries under dental sealants or an amalgam restoration,although it will detect decay around the occlusal margins of a restoration.
A carious tooth will show more fluorescence,and a clean,healthy tooth will show less fluorescence.
A laser caries detector is equally effective in both primary and permanent teeth.
