Clinical Performance of Nanohybrid Resin Composite Lined With PRG Barrier Coat Compared to Resin Modified Glass Ionomer in Class V Carious Cavities Over 18 Months: Randomized Clinical Trial

Cairo University (CU)

Status: Not yet enrolling

Conditions: Class V Dental Caries

Treatments: Device: resin modified glass ionomer; Device: PRG barrier coat + nanohybrid composite

Study type: Interventional

Funder types: Other

Identifiers

NCT05605457

PRG barrier coat liner Class V

Details and patient eligibility

About

Class V carious lesions will be restored using two different restorative materials either Resin modified glass ionomer or nanohybrid resin composite lined by PRG barrier coat. Each restoration will be evaluated for clinical parameters after finishing and polishing at baseline, at 6 months, 12 months and at 18 months. The restorations will be clinically examined according to modified USPHS criteria in terms of retention, marginal adaptation, marginal discoloration, secondary caries and postoperative sensitivity.

Full description

Class V carious lesions will be restored using two different restorative materials either resin modified glass ionomer or nanohybrid resin composite lined by PRG barrier coat.Each restoration will be evaluated for clinical parameters after finishing and polishing at baseline, at 3 months, 6 months, 12 months and at 18 months. The restorations will be clinically examined according to modified USPHS criteria in terms of retention, marginal adaptation, marginal discoloration, secondary caries and postoperative sensitivity.

30 participants in 2 patient groups

PRG barrier coat

Experimental group

Description:

It is a light cured surface-partially reacted glass (S-PRG) filler particles with a multifunctional glass core embedded in a resin matrix.

Treatment:

Device: PRG barrier coat + nanohybrid composite

Resin modified glass ionomer

Active Comparator group

Description:

Resin modified glass ionomer (Fuji II LC, GC, Japan). RMGIC are glass-ionomer cements with small quantity of monomers and initiators so the acid-base reaction is supplemented by a second polymerization reaction.

Treatment:

Device: resin modified glass ionomer
