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.
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.

| Measure | Description | Time Frame |
|---|---|---|
| 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 | 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. | -Shade measurements will be taken at baseline, one week, one month, 3 months and 6 months using the following methods:
| Assessment at baseline, 6 months and 1 year after the restorations of the teeth. |
