Official title

Color Stability and Wear Resistance of Direct Flowable and Preheated Resin Composite Veneers Using the Injectable Resin Technique: A Randomized Controlled Clinical Trial.

Overview

The aim of this study is to conduct the first clinical trial to assess the color stability and wear resistance of the highly filled injectable flowable composite materials compared to preheated conventional ones and evaluate the in vivo performance of the injectable composite technique.

Detailed description

The design of study will be a modified split-mouth randomized clinical trial with two study groups. 20 patients will be recruited with the need of at least 6 anterior aesthetic restorations. A total of 142 restorations will be assigned into two groups. In the first group, 71 anterior teeth will be restored with flowable composite veneer restorations, and the second group 71 anterior teeth will be restored with heated composite veneer restorations. Both treatment groups will be done using the injectable resin technique. The following parameters will be evaluated at baseline, 6 months and 12 months of clinical service. Color stability will be evaluated using the Vita classical shade guide and a spectrophotometer. Wear resistance will be evaluated by measuring the volumetric material loss through superimposition of images taken at each follow up on baseline images taken by scanning of gypsum replicas using a 3D laser scanner. Clinical performance will be evaluated using the USPHS criteria. It is expected that the color stability, wear resistance and clinical performance of the heated composite restorations will be superior to the flowable restorations.

Interventions

  • Other Experimental: Group1: Estelite Sigma Quick
    Preheated conventional composite (Estelite Sigma Quick, Tokuyama Dental Corp, Tokyo, Japan). Estelite Sigma Quick is a resin composite with the following composition (Silica-zirconiasupra-nano, monodispersingc spherica, Bis-GMA, UDMA, TEGDMA).
  • Other Experimental: Group 2: Estelite Flow Quick
    Second group: Injectable flowable (Estelite Flow Quick, Tokuyama Dental Corp, Tokyo, Japan). Estelite Flow Quick is a resin composite with the following composition (Silica-zirconia, supra-nano monodispersing spherical, Bis-GMA, UDMA,TEGDMA).

Primary outcome measures

  • The wear resistance of the injectable flowable composite veneers compared to their preheated resin composites counterparts. [Time frame: Assessment at baseline, 6 months and 1 year after the restorations of the teeth.]
  • The color stability of the injectable flowable composite veneers compared to their preheated resin counterparts. [Time frame: Assessment at baseline, 6 months and 1 year after the restorations of the teeth.]

Eligibility criteria

Inclusion criteria

  • Restorations in functional occlusions with an opposing natural tooth.
  • Two proximal contacts area with neighboring teeth

Exclusion criteria

  • Patients with contra-indications for regular dental treatment based on their medical history.
