Clinical & Radiographic Outcomes of the Hall Technique Versus Conventional Pulpotomy in Carious Primary Molars

Abstract

Background: Successful management of carious primary molars requires predictable clinical and radiographic outcomes while maintaining patient comfort and clinical efficiency. The Hall Technique has been proposed as a minimally invasive alternative to Conventional Pulpotomy; however, direct comparative evidence remains limited.

Aim: To evaluate and compare the clinical success, radiographic success, and chairside treatment time of the Hall Technique and Conventional Pulpotomy in the treatment of carious primary molars.

Materials and Methods: This randomized clinical study included 60 children aged 4–8 years, each contributing one carious primary molar. The teeth were randomly assigned to either the Hall Technique group or the Conventional Pulpotomy group. Clinical and radiographic assessments were conducted at 3, 6, and 12 months. Chairside treatment time was recorded for both interventions. Statistical analysis was performed using appropriate tests, with the level of significance set at p < 0.05.

Results: At the end of the 12-month follow-up, both treatment modalities demonstrated high success rates. Clinical success was achieved in 93.3% of teeth treated with the Hall Technique and 90.0% of those treated with Conventional Pulpotomy, while radiographic success was observed in 93.3% and 86.7% of teeth, respectively. These differences were not statistically significant. In contrast, the mean chairside treatment time was significantly shorter for the Hall Technique (11.4 ± 2.1 minutes) compared with Conventional Pulpotomy (27.8 ± 3.9 minutes) (p < 0.001).

Conclusion: Both the Hall Technique and Conventional Pulpotomy provided comparable clinical and radiographic outcomes over a 12-month period. However, the Hall Technique required significantly less chairside time, supporting its use as a more efficient and child-friendly approach for managing carious primary molars.
