Clinical Trial Summary
This trial will be conducted to compare the clinical performance between a new bioactive
resin composite material and high viscosity glass ionomer for restoring occlusal carious
lesions of posterior teeth in patients scheduled for head and neck radiotherapy.
Description:
Inspite of recent developments in the materials' science, some novel materials require direct
association with components of the oral cavity for renewal or recharging of the constituents
of the restoration to enhance marginal integrity and thus decrease bacterial microleakage,
marginal discoloration and postoperative hypersensitivity . There is a constant increase in
aesthetic demand for a material that ensures near to perfect adhesion to the tooth surface in
order to minimize microleakage and improve marginal integrity. Microleakage forms the basis
for predicting the performance of any restorative material Bioactive restorative materials
have been introduced for numerous utilizations in dentistry. Among these are fluorides for
remineralization; antibacterial resins and restoratives that release and recharge fluorides,
phosphate and hydroxyle ions and thus can enhance marginal integrity . Bioactive restorative
materials are reported to release more fluoride than glass ionomers. Additionally, they react
to pH changes in the mouth by uptaking calcium, phosphate, and fluoride ions to maintain the
chemical integrity of the tooth structure.
It is proposed that contemporary bioactive esthetic materials, which associate with oral
fluids and show recharge and renewal of restorative material constituents, have the potential
to reduce bacterial microleakage and enhance marginal integrity, One possible approach to
increase the resistance of restorations to secondary caries formation is to use bioactive
materials ( Like predicta bilk fil composite) that contain agents which negatively influence
the micro-organisms and/or promote remineralization of tooth structure.
High viscosity glass ionomer (EQUIA Fil) has new technology that contains ultrafine and
highly reactive glass diffused within the glass-ionomer fillers to increase and enhance
matrix formation. This system allows ion availability and builds a stronger matrix structure
with greater physical properties, wear resistance and fluoride release.
