ART and Hall Technique for the Management of Occlusal-proximal Caries in Primary Molars: A Randomized Clinical Trial
In Brief
A clinical study evaluating Atraumatic Restorative Treatment and Hall Technique for Dental Caries. Completed, enrolled 131 participants.
Detailed Summary
The aim of this, two-arm, parallel group, patient-randomised controlled, superiority trial is to evaluate the survival rate of approximal Atraumatic Restorative Treatment (ART) restorations compared to the Hall Technique (HT) placed in a school setting. The investigators will recruit 120 schoolchildren (5-10 years) with at least one occlusal-proximal carious lesion in primary molar. They will be randomized and treated following best-practice protocols to either receive an ART restoration using the high-viscosity glass ionomer cement (EQUIA Forte, capsules, GC Corp.) or a preformed metal crown placed using the HT (3M ESPE) cemented with glass ionomer luting cement (Fuji I Capsules, GC Corp.). Baseline measures and outcome data (at reviews over a three year period) will be assessed through participant report, clinical examination and parent report/ questionnaires.

Timeline
Interventions
No local anaesthesia will be used. Infected carious tissue will be removed with hand instruments, and the cavities restored with Glass Ionomer Cement (GIC).The cavity will be filled with GIC. After the press-finger technique, the excess of material will be removed.
It employs the cementation of preformed metal crowns (PMC) without the need of any prior teeth preparation or caries removal. No local anesthesia is used neither tooth preparation.Different sizes of PMCs will be tested until the smallest size that perfectly fit the tooth is achieved. The PMC will be loaded with the dental material glass ionomer cement (GIC) and placed. Child will asked to bite firmly on it, until it is fitted. The excess of GIC will be removed with hand instruments and dental floss.
