Hall technique for managing carious primary molars shows good long term outcomes.

There is a growing literature supporting caries management options where caries is sealed in beneath restorations or sealants. The aim of this trial to compare long-term (at 5 yrs) outcomes for carious primary molars managed by GDPs’ standard conventional restorative methods (control) with the Hall Technique in general dental practice.   The outcomes at 2 years have been reported previously ( Innes et al 2007)

This was a split-mouth randomised controlled trial involving 17 general dental practitioners. 132 (3-10 yr-old children ) with caries affecting matched pairs of asymptomatic primary molar teeth were included. were randomised with one tooth allocated to restoration with the Hall Technique, and the contralateral tooth allocated to the control (the dentists usual treatment option). Annual clinical and radiographic follow-up data were recorded. The major outcomes were: irreversible pulpitis or dental abscess requiring pulp therapy or extraction, inter-radicular radiolucency, restoration loss and tooth unrestorable, and internal root resorption.

Ninety one patients (69%) had 48 months’ minimum follow-up. there was a statistically significant increased risk of for both Major (p < 0.000488)  and minor  failures( p <0.000001) when a control restoration had been placed compared with a Hall Technique. There were only 3 major failure in teeth treated with the Hall technique ( see table).

The authors concluded

At 60 months, for teeth with a minimum of 48 months’ follow-up, sealing-in caries by the Hall Technique statistically, and clinically, significantly outperformed the GDPs’ standard restorations.
