Comparing Color Stability and Wear Resistance of Injectable Flowable and Preheated Resin Composite Veneers in Anterior Teeth Using the Injectable Resin Technique

What this Trial Is About

Researchers are evaluating the color stability and wear resistance of two types of injectable composite materials used for anterior aesthetic dental restorations. This clinical trial compares highly filled injectable flowable composite materials with preheated conventional composites to assess their performance in vivo using a randomized controlled design. The study involves 20 patients needing at least six anterior restorations each, with a total of 142 restorations assigned to two groups. One group will receive anterior teeth restorations using flowable composite veneers, while the other group will have heated composite veneers applied. Both groups will be treated using the injectable resin technique. The trial will assess these restorations at baseline, 6 months, and 12 months. Parameters evaluated include color stability using a shade guide and spectrophotometer, and wear resistance by measuring material loss through 3D laser scanning of gypsum replicas. Clinical performance will be measured by USPHS criteria. Participants will undergo evaluations at the start of the study and during follow-ups at 6 months and one year. Assessments include color matching, volumetric wear measurement, and clinical performance checks. The study tracks changes over time to compare the two composite types. The total duration of participation spans one year after the restorations, with monitoring to determine which material maintains better color and durability.
