Dental Assistant State Licensing Examination (DASLE) Practice Exam

Question: 1 / 400

How far should the light tip be placed from the tooth during the curing process?

5-6mm from the tooth

1-2mm from the tooth

The ideal distance for the light tip during the curing process is 1-2mm from the tooth. This range ensures optimal curing of dental materials such as composites, as being too far away might reduce the effectiveness of the light on the material, resulting in insufficient curing. The closer proximity enhances the intensity and concentration of the light, allowing it to penetrate adequately and activate the photoinitiators in the resin material, leading to a proper bond and strong restoration. Proper distance is crucial for achieving the desired hardness and longevity of the material used in dental procedures.
