Measure
Standard Care
Fifty patients will be recruited into standard treatment group and they will receive composite resin restoration for all decayed teeth and standard preventive treatment (cleaning and fluoride varnish application) at baseline. Composite restoration and tooth cleaning: Standard preventive treatment will be repeated on semi-annual (6-month) recall visits. All composite restorations will be placed according to the manufacturer's instruction.
Plasma Treatment
Fifty patients will be recruited into plasma treatment group and they will receive plasma treatment after cavity preparation, composite resin restoration, standard preventive treatment followed by plasma treatment for non-carious teeth. Plasma treatment: plasma treatment after preparation and for caries prevention

Standard Care
n=34 Participants
Fifty five patients were recruited into standard treatment group and they will receive composite resin restoration for all decayed teeth and standard preventive treatment (cleaning and fluoride varnish application) at baseline. Composite restoration and tooth cleaning: Standard preventive treatment will be repeated on semi-annual (6-month) recall visits. All composite restorations will be placed according to the manufacturer's instruction.
Plasma Treatment
n=29 Participants
Forty seven patients were recruited into plasma treatment group and they will receive plasma treatment after cavity preparation, composite resin restoration, standard preventive treatment followed by plasma treatment for non-carious teeth. Plasma treatment: plasma treatment after preparation and for caries prevention

PRIMARY outcome

Timeframe: 12 months

Population: After 12 months, in standard care group, we had 27 participants remaining and lost 28 participants; in plasma treatment group, we had 21 participants remaining and lost 26 participants. Units of analysis for composite restoration failure is number of composite restorations in each group. A participant may have more than one composite restoration.

Composite restoration evaluation for fracture or loss of filling partially or completely, with or without recurrent caries.
