Brief summary
Dental manufacturers' constant tweaks and improvements to composite compositions have resulted in a wider spectrum of restorative materials with positive long-term clinical performance. For example, the creation of bioactive giomer material with proven continuous multi-ion release has been beneficial in avoiding demineralization and imparting acid resistance to enamel and dentin.
Detailed description
Giomer resin not only reduces the risk of secondary caries around restorations by releasing fluoride ions, but it also has good esthetic, physical, and handling features. Furthermore, advancements have been made to reduce giomer resin polymerization shrinkage by incorporating filler technology into the matrix system. As a result of these efforts, giomer resin is currently distinguished by its low shrinkage feature. According to the manufacturer, low shrinkage giomer resin has volumetric shrinkage of 0.8% and a polymerization shrinkage stress of 2.72 MPa. Several investigations were carried out to examine the overall clinical performance of low shrinkage giomer resin with equivalent success rates when compared to other restorative materials. The aim of the current study is to evaluate the effect of giomer in maintaining pulp health and dentin bridge formation after partial caries removal in permanent teeth with deep occlusal carious lesion when compared to resin composite restoration.
Interventions
PROCEDUREBeautifil II LS (Low-Shrinkage)
The most remarkable feature of this light-cured universal composite for anterior and posterior restorations is its unique shrinkage of 0.85 percent by volume
PROCEDURENanohybrid resin composite
Nanohybrid resin composites are the most popular, because they improve the distribution of fillers in the matrix by combining nanoparticles with submicron particles to achieve better mechanical, chemical, and optical properties

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Success rate | From enrollment to the end of treatment at 24 months | The primary outcome of the present clinical trial is success rate, expressed as a binary variable indicating whether the restored tooth maintained its pulp vitality after 24 months. Success will be evaluated by a positive response to cold pulp testing, absence of spontaneous pain, no tenderness to percussion, absence of periapical radiolucency. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Dentin bridge formation | From enrollment to the end of treatment at 24 months | Dentin bridge formation will be evaluated by digital radiographs taken with standardized exposure parameters according to standardized procedure by placement of film holders in paralleling technique. Dentin bridge formation will be measured by millimeters (mm) |
