Occlusal Caries Clinical Trial
Official title:
Performance of Flowable Giomer Versus Nanofilled Flowable Composite With or Without Giomer Coat In Conservative Occlusal Cavities: 18 Months Randomized Clinical Trial
With limited evidence-based information in literature the goal of this clinical trial is to learn about Flowable Giomer and compare it to Nanofilled Flowable Composite in Conservative Occlusal Cavities. It is beneficial to evaluate the newly introduced material using a randomized controlled clinical trial to test the null hypothesis that this new flowable giomer (Shofu™ Beautifil Injectable X, Shofu Dental Corp., Japan) and conventional resin-based nano-filled composite (Filtek™ Z350 XT 3M ESPE, USA) which will then be coated with (Shofu™ PRG Barrier Coat, Shofu Dental Corp., Japan) will have the same clinical performance as flowable resin composite as a preventative restorative restoration in permanent molars.
This study will be conducted to clinically evaluate caries prevention and marginal integrity of flowable giomer and flowable resin composite coated with S-PRG in comparison to flowable resin composite as a preventative resin restoration in patients requiring minimally invasive simple class I cavities in permanent molars over 18 months test period. Teeth that meet the inclusion criteria will be selected. The occlusal surfaces will be cleaned by pumice and a low speed polishing brush. Baseline recording of carious lesions will be carried out using DIAGNOdent pen. Cavity preparation will be carried out using number 330 (Mani, Inc., Japan) bur. All the tested materials Shofu™ Beautifil Injectable X, (Shofu Dental Corp., Japan flowable composite) and Filtek™ Z350 XT (3M ESPE, USA) Flowable composite: Conventional resin-based nano-filled flowable composite which will then be coated with Shofu™ PRG Barrier Coat, (Shofu Dental Corp., Japan) will be used according to manufacturer instructions and comparator restorative material Filtek™ Z350 XT (3M ESPE, USA) Flowable composite. All restorations will be finished using flame-shaped finishing stone (Mani, Inc., Japan) and polished using rubber cups (Kerr Corporation, Orange, CA, USA). The primary and secondary outcomes will be measured at four intervals 1 week after placement, 6 months follow up, 12 months follow up and 18 months follow up. ;
