Brief Summary

The aim of this randomized clinical trial study is to compare the longevity of Atraumatic Restorative Treatment (ART) using high viscosity GIC and Conventional Treatment using composite resin under rubber dam isolation and local anesthesia (CT) in primary molars. As secondary outcomes, cost-efficacy, self-reported discomfort and cooperation will also be tested. Children aging between 3 to 6 years old presenting at least one occlusal and/or occlusoproximal cavity will be randomly assigned to one of two groups according to the dental treatment: ART (experimental group) or CT (control group). The dental treatment will be performed at a dental care trailer located in a Public School in Barueri (São Paulo, Brazil). The unit of analysis for randomization will be the child. A number of 204 teeth presenting occlusal cavities and 240 teeth presenting occlusoproximal cavities were set after sample size calculation. The primary outcome will be the restorations' longevity, which will be assessed after 6, 12, 18 and 24 months by two evaluators through clinical examination according to Frencken et al. (1998) criteria for occlusal restorations and Roeleveld et al. (2006) criteria for occlusoproximal restorations. The time spent during the dental treatment and all materials used will be considered for estimating the cost-efficacy of each treatment. The individual's discomfort will be also measured after each dental procedure using the Facial Scale of Wong-Baker. Cooperation will be assessed by the operator using a 5-point scale.

Outcome Measures

Primary Outcomes (1)

  • The restoration survival

    The treatments will be classified as successful when they present a clinical satisfactory aspect. Otherwise, "minor failures" will be analyzed. "Minor failures" are those in which there is a defect in the restoration/crown, but it does not interfere with the tooth health.

    Every 6 months up to 24 months.

Secondary Outcomes (3)

  • Cost-efficacy assessment

    Through study completion, an average of 24 months

  • Child self-reported discomfort

    Immediately after treatment

  • Cooperation

    Immediately after treatment

Study Arms (2)

Conventional Treatment

ACTIVE COMPARATOR

Occlusal and occlusoproximal composite resin restorations in primary molars (rubber dam isolation + Adhesive system + composite resin Filtek z350)

Procedure: Conventional Treatment

ART using Fuji IX

EXPERIMENTAL

Occlusal and occlusoproximal ART restorations in primary molars with GIC Fuji IX

Procedure: ART using Fuji IX

Interventions

Occlusal and occlusoproximal ART restorations in primary molars using the high viscosity GIC Fuji IX will be performed under relative isolation. No local anesthesia will be used. Infected carious tissue will be removed with hand instruments, and the cavities restored with GIC. After the press-finger technique, the excess of material will be removed and occlusion will be checked. For occlusoproximal restoration, an adapted matrix strip with a wooden wedge will be used to assure appropriate contour.

ART using Fuji IX

Occlusal and occlusoproximal composite resin restorations in primary molars using the Scotchbond Multi-purpose adhesive system and the Filtek Z-350 composite resin wil be performed. Local anesthesia will be used. Absolute isolation will be performed using rubber dam and clamp. Removal of unsupported enamel will be performed using a round bur. Infected carious tissue will be removed with hand instruments. The cavity will be etched using 37% phosphoric acid for 15 seconds followed by rising and drying for the same amount of time. The cavity will be restored with composite resin. Occlusion will be checked. an adapted matrix strip with a wooden wedge will be used to assure appropriate contour.
