Clinical Assessment of Giomer Based Technology Versus Smart Bioactive Restoration in Carious Class V Cavities

Cairo University34 enrolled

Overview

This study will compare between S-PRG-containing injectable flowable resin composite (Beautifil Flow Plus X) and smart bioactive flowable resin composite (Activa bioactive restorative) through evaluation of the modified USPHS clinical performance in patients with carious class V moderately deep cavities.

Bioactive glass has an amorphous structure, whereas glass-ceramics are crystallized glasses and composites of a crystalline phase in a residual glassy phase. Bioactive glass consists solely of the elements found in the body material, mainly being silicon (Si), calcium (Ca), sodium (Na), phosphorous (P), and oxygen (O) . Among the diverse kinds of bioactive glass filler, surface pre- reacted glass ionomer (S-PRG) filler has already been used for a relatively long time in some specific commercial RBCs. Most studies investigating this material assortment have focused on ion-release degree and potentially associated antibacterial effects. The restoration's surface integrity may be a key factor determining the eventual clinical beneficial effect of the alleged antibacterial properties. The antibacterial efficacy of bioactive glass depends on the concentration of the ions released from the glass. As inorganic bioactive fillers, S-PRGs have the additional ability to release ions. S-PRG filler is considered a multifunctional bioactive glass because it can release several types of ions including Al, B, F, Na, Si, and Sr. The released ions can exhibit a variety of bioactive behaviors, such as preventing fungal and bacterial adhesion, antibacterial activity, neutralizing acids, inhibiting demineralization, and enhancing remineralization. The biological effects of S-PRG fillers have been studied for several types of oral pathogens. It was reported that the elute of the S-PRG filler has a protective effect against Streptococcus mutans. Moreover, the elute of S-PRG filler reduced the density and thickness of the formed biofilm.

Beautifil Flow Plus X.PROCEDURE

Class V cavities will be prepared, Selective etching technique will be used with phosphoric acid etching gel for 15 seconds on enamel.Single Bond TM Universal will be applied to cavity walls and margins with agitation for 20 seconds.The adhesive will be light-cured for 20 seconds. Then Beautifil Flow Plus X composite will be placed

Activa bioactive restorativePROCEDURE

Class V cavities will be prepared, Selective etching technique will be used with phosphoric acid etching gel for 15 seconds on enamel. Bonding agent will be applied on the entire cavity and light-cured for 20 seconds then Activa bioactive restorative composite will be applied and cured for 20 seconds.

Outcomes

Primary Outcomes

Assessment of Modified USPHS Criteria (Marginal discoloration) change over time

Alfa: there is no visual evidence of marginal discoloration different from the color of the restorative material and from the color of the adjacent tooth structure. Bravo: there is visual evidence of marginal discoloration at the junction of the tooth structure and the restoration that has not penetrated along the restoration in a pulpal direction. Charlie: there is visual evidence of marginal discoloration at the junction of the tooth structure and the restoration, but the discoloration has penetrated along the restoration in a pulpal direction.

Time frame: Change between baseline,6 months and 12 months

Secondary Outcomes

Assessment of Modified USPHS criteria. (Secondary caries) change over time

Alfa: no caries is present. Charlie: caries is present.

Time frame: Change between baseline,6 months and 12 months
