Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Flowable Giomer

Patients with conservative carious class I occlusal cavities will be treated with Shofu™ Beautifil Injectable X, Shofu Dental Corp., Japan flowable composite Novel bio-active flowable resin containing nano S-PRG (Surface Pre-Reacted Glass ionomer).

Group Type EXPERIMENTAL

Flowable Giomer

Intervention Type OTHER

Pre-reacted Glass Ionomer (PRG) filler is added to resin to create giomer, a dental adhesive material. Fluoride release and recharge, acid resistance, an anti-plaque effect, dentin remineralization, and acid buffering capacity are some of the benefits of giomer.

Nano-filled Flowable Composite with S-PRG barrier coat

Patients with conservative carious class I occlusal cavities will be treated with 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.

Group Type EXPERIMENTAL

Flowable Nano-filled composite with S-PRG barrier coat

Intervention Type OTHER

Flowable composites are claimed to have a higher wetting ability of the tooth surface and thus ensure penetration into all surface irregularities in layers of minimal thickness. As a result of the higher amount of filler particles, it is noted that flowable composites have less porosity than conventional resin-based sealants. Moreover, flowable composite materials have better mechanical properties which lead to increased durability and longevity of the restoration.

The PRG Barrier Coat is a resinous coating substance that shields the enamel surface from demineralization brought on by acidic attack. Near the coated surface, S PRG filler ions in PRG Barrier Coat have been found to have an acid-neutralizing effect. F and Sr released by PRG Barrier Coat can be effectively absorbed by the tooth substrate to prevent demineralization thus hindering the progression of caries.
