Hall Technique Compared to Orthodontic Band Cementation in Carious Injuries in Deciduous Teeth of Children with...

The aim is to evaluate the longevity of the Hall Technique (HT) compared to orthodontic bands (BOCIV) for treating carious lesions in the deciduous molars of children with disabilities.

A total of 58 children with cognitive impairments, diagnosed with mild to moderate learning disabilities, aged 4-10 years, presenting with carious lesions classified as scores 5/6 in deciduous molars, were included. The sample consisted of 100 teeth, divided into two groups: HT, n = 50; and BOCIV, n = 50. Clinical and radiographic follow-ups were conducted at 6 and 12 months. Kaplan-Meier survival curves and log-rank tests were used to compare the two groups. Cox regression analysis was performed to assess the influence of other variables.

After 12 months, 72 teeth were reevaluated. A total of 100 teeth were reevaluated at least once during the study and included in the survival analysis. HT showed superior performance (88% survival) compared to the BOCIV (66% survival). Regarding marginal adaptation, BOCIV showed a higher frequency of subgingival extension, whereas the HT group exhibited better proximal contact preservation.

Orthodontic bands cemented with conventional glass ionomer (BOCIV) may be considered an alternative treatment for extensive carious lesions in deciduous molars; however, HT demonstrated superior survival, marginal adaptation, and proximal contact retention.

This study highlights a treatment option for these carious lesions in deciduous molars for children with disabilities. The study was registered in the Brazilian Registry of Clinical Trials (REBEC) under the number RBR-825qxqw.
