About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Patients older than 18 years

Asymptomatic sound anterior teeth, or localized Class III/IV/V cavity or restoration

Patients with irregular tooth anatomies, misalignments, spacing, mild staining, cervical wear that are indicated for direct composite veneers

Restorations in functional occlusions with an opposing natural tooth.

Disqualifiers

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

Patients at a high risk of caries.

Patients with poor oral hygiene.

Teeth with compromised periodontal status.

Treatments tested in this trial

  • Experimental: Group1: Estelite Sigma Quick

    Other intervention

    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).

  • Experimental: Group 2: Estelite Flow Quick

    Other intervention

    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).

Trial outcomes

Primary outcomes

1

The wear resistance of the injectable flowable composite veneers compared to their preheated resin composites counterparts.

Participants will be assessed at baseline, directly after the finishing and polishing procedure, and at review visits according to the following criteria: -The gypsum replicas will be scanned three-dimensionally using a 3D laser scanner at baseline, 6 months and 12 months of clinical service, to analyse the volumetric material loss, which can be associated with structural wear, using 3D analysis software (Medit Link, Medit, Seoul, Republic of Korea) \[28, 29\] \[30\] \[31\] \[32\]. Follow up images will be superimposed on baseline images

Time frame
Assessment at baseline, 6 months and 1 year after the restorations of the teeth.
2

The color stability of the injectable flowable composite veneers compared to their preheated resin counterparts.

-Shade measurements will be taken at baseline, one week, one month, 3 months and 6 months using the following methods: 1. Using a spectrophotometer (VITA Easyshade V; VITA Zahnfabrik, Bad Säckingen, Germany), color values (L\*, a\*, b\*) according to the Commission Internationale d'Eclairage (CIELab) will be taken at the middle of each restored tooth using a customized jig to fix the position and in the afternoon with sunlight and standardized room illumination and at each evaluation period. The color changes will be determined using the CIEDE2000 formula. 2. Using Vita classical shade guide (Vita Zahnfabrik, Bad Säckingen, Germany) and a professional photograph before treatment, at baseline and at each review visit.

Time frame
Assessment at baseline, 6 months and 1 year after the restorations of the teeth.
