- Brief Summary
One of the main difficulties encountered in esthetic dentistry is the complexity associated with shade matching and layering technique to achieve optimal esthetic outcomes. To ensure an esthetic outcome, an imperceptible match of the color of the restorative material to that of the tooth is of utmost importance. Recently, a new shade matching composite that utilizes "smart chromatic technology", developed by Tokuyama was claimed to be able to capture the structural color of its surroundings teeth. Our main objective is to assess the blending capacity of OMNICHROMA composite material in anterior restorations of patients attending the Jordan University Hospital. Both visual and instrumental measurements will be performed and the differences between the shade of the composite resin and the tooth structure will be measured. In addition, multi chroma composite restorations will be placed for the purpose of comparison (control).
- Detailed Description
In the present study, the restorations will be placed under rubber dam isolation for moisture control. The cavities will be prepared according to the concepts of minimal invasive dentistry. Prior to placing the composite resin, the margins of the cavities will be finished using ultra fine grit diamond burs·and beveled in a 1-mm area. Deep cavities suspected to be near the pulp be lined with RMGI. Inclusion criteria: class Ill and Class IV carious lesions.
The enamel margins of the cavities will be acid etched for 60s with 37% phosphoric acid and then rinsed thoroughly with water spray. Afterwards, the dentin bonding system will be applied, left undisturbed for 20 s and then excess removed using an air syringe and light cured for 20s. The restorative composite material will be placed in incremental layers, adapted, each layer cured for 40s. After polymerization, the restorations will be finished under profuse water spray using diamonds, Sof-Lex finishing discs and polishers.
All restorations will be placed by one dentist (Pl). Written informed consent will be provided to all participants prior to starting the treatment
