NCT05605457

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Modified USPHS criteria

    Retention, marginal discoloration, marginal adaptation, secondary caries

    18 months

Secondary Outcomes (1)

  • Modified USPHS criteria

    18 months

Study Arms (2)

PRG barrier coat

EXPERIMENTAL

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

Device: PRG barrier coat + nanohybrid composite

Resin modified glass ionomer

ACTIVE COMPARATOR

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.
