Clinical Relevance Among the factors that significantly influence the depth of cure of resin composite restorations—the distance between the tip of the light source and the restorative material—as well as the geometry of the tip, are crucial parameters. Increasing the ratio between the entry and exit diameter of the tip will result in an improvement in the depth of cure for lower distances between the tip of the light source and the restorative material, while decreasing the ratio of the depth of cure, which will be higher for greater distances.

Dental Professional

Clinical Relevance Different light curing units, the thickness of the resin composite increments and the exposure distance to a curing light may change the physical properties of a restorative material and compromise its mechanical behavior under clinical loading conditions. Understanding how these factors can affect the quality of restorative products may help the dental professional in selecting the best activating source for a specific clinical application.

All adhesive systems performed best when bonded to enamel compared to dentin surface anatomy. Clinicians should be aware that strict adherence to manufacturer instructions, when using these materials, is of primary importance.
