Esthetics of Dental Composite and Adhesive System

Cavities of Teeth Clinical Trial

Official title: Esthetic Outcomes of a Newly Developed Dental Composite and Adhesive System: a Randomized Clinical Trial

Status Active, not recruiting

Clinical Trial Summary

To compare a newly developed filling composite to a current filling composite system. Two restorations will be placed in each subject, one using system A and one using system B. The first system listed in the randomization pair will be placed on first tooth (#4-#13), and the second system on 2nd tooth (#4-#13). The same three researchers will be responsible for placement of all the restorations.

Clinical Trial Description

The aim of this (12-month; 36-month; 60-month) randomized controlled clinical trial is to evaluate and compare the esthetic outcomes and patient satisfaction of a simplified newly developed dental composite system (system A)for the esthetic region to a nanohybrid composite system (Filtek Supreme Ultra-system B) placed in class III, IV and V lesions. Even though dental composite systems have been used extensively for the anterior region, clinicians face challenges with shade selection and longevity of the material over the years. This new system has been developed to improve the esthetic outcomes and patient satisfaction by enhancing the blending capability of the material.

Dental composite systems have been used for 50 years as state of art materials to restore the anterior region. Significant development has occurred regarding the composition and structure of dental composites, improving the longevity of these restorations; however, clinicians are faced with the challenge of selecting the most adequate shade and restorative technique to reproduce missing tooth structure.

Depending on the size of the cavity preparation, a single layer of material or multiple layers might be needed to reproduce dentin and enamel. Different dental composite systems offer multiple body, dentin, and enamel shades. Therefore, clinicians are faced with the challenge of recreating nature using this material. Different devices, such as spectrophotometers have been introduced on the market for shade selection. However, one of the most important aspects when placing anterior composites is the esthetic outcome based on the patient's assessment. Therefore, this study will evaluate the esthetic outcomes of a simplified and a conventional dental composite system based on the provider's and patient's assessment. ;
