44 - Retrospective Review of Hall Crown Outcomes

Abstract:

Purpose: The goal of this research was to review radiographs of teeth before and after hall crown placement. Teeth were followed until extraction, natural exfoliation, or unknown results were determined.

Methods: A total of 750 crowns were placed and evaluated. Pre-op radiographs were graded with an ICDAS score. Pre-op clinical signs and symptoms were recorded if present. The first follow up with or without radiographs was recorded. Clinical signs and symptoms were noted if any. Radiograph type and if the crown was seated and sealed was noted. Total length of follow up times were recorded. Outcome of success was recorded by: extraction, natural exfoliation, or unknown result.

Results: The final model included 627 crowns. The full data model found that seal and P failure compared to D3 were the only variables that were statistically significant. Seal (HR: 0.107; 95% CI: 0.05, 0.229; p < 1e-8). ICDAS (HR: 17.593; 95% CI: 5.509, 56.179; p <0.0001)

Conclusion: Hall crowns are a great treatment option for cooperative or uncooperative patients. Hall crowns have a high success rate for all carious lesions without clinical or radiographic signs of infection and if the crown is sealed and the decay is not in the pulp. Although there is an increased risk of failure for pulpally involved carious lesions and hall crowns that do not seal out the decay, hall crowns are shown to have high success rates, and should be considered when treating all carious teeth.
