Brief Summary

Tooth decay is one of the most common chronic infectious disease found in children worldwide and if left untreated, is rapidly progress. Severe tooth decay in children is not only affect child's health and school performance, but also has impact on the family well-being. Oral rehabilitation in children requires time, resources and effort of dental specialists, the child and parents. Caries is a destructive condition of organic and inorganic components of the tooth structures but reversible and most importantly, preventable. Topical fluoride therapy, delivered by dentists has been effectively used to speed up the repair process as well as to strengthen the surface of intact tooth structure. Topical fluoride is available in various preparations. Regular application of sodium fluoride varnish is every three months, by far, considered as effective method in preventing new caries, particularly in the high-risk children. It has the advantage of containing therapeutic concentration of fluoride and ability to flow over and stick to the tooth surface. Whereas silver ion and relatively higher fluoride concentration in Silver Diamine Fluoride (SDF) has been shown to be the most effective in harden the decay, stop the caries progress and eliminate pathogenic bacteria. It can be hypothesize that when use in combination in school children, both reagents might have synergistic effect on arresting existing caries as well as preventing new caries.

Outcome Measures

Primary Outcomes (1)

  • Number of arrested caries lesion changed from baseline

    Number of arrested caries lesion changed from baseline. The arresting dentine caries lesion was evaluated at 18 months after first application. Evaluation criteria included the condition of the hardness and discoloration of carious lesion. The carious lesion was re-categorized as a binary outcome: Dental caries (active/inactive)

    18 months

Secondary Outcomes (10)

  • Increasing number of new caries lesion from baseline

    6 months

  • Increasing number of new caries lesion from baseline

    12 months

  • Increasing number of new caries lesion from baseline

    18 months

  • Parental satisfaction

    2 weeks

  • Parental satisfaction

    18 months

  • +5 more secondary outcomes

Study Arms (3)

SDF arm

EXPERIMENTAL

SDF arm is application of 38% silver diamine fluoride solution (SDF) on cavitated caries in primary molar, , cavities in anterior teeth will be applied only on additional consent obtained.

Device: SDF

Fluoride varnish arm

EXPERIMENTAL

Fluoride varnish arm is application of 5% sodium fluoride varnish on all surface of every tooth.

Device: Fluoride varnish

Combination arm

EXPERIMENTAL

Combination arm is application of 38% silver diamine fluoride solution(SDF) on cavitated caries in primary molar, , cavities in anterior teeth will be applied only on additional consent obtained and then apply of 5% sodium fluoride varnish on all surface of every tooth.

Device: SDFDevice: Fluoride varnish
