Clinical outcomes of selective removal to soft dentin versus firm dentin for deep caries lesions: a randomized controlled trial up to 5 years

Clinical Outcomes of Selective Dentin Removal for Deep Caries

Study Overview

This study compared two methods for treating deep caries in permanent teeth: selective removal to soft dentin (SRSD) with or without calcium silicate (CS) and selective removal to firm dentin (SRFD).

Study Details

Conducted from November 2018 to March 2020, the study involved 165 deep caries lesions in 134 patients. Participants were divided into:

  • Control Group: 46 patients treated with SRFD and CS.
  • Test Group: 101 patients receiving SRSD, further split into:
    • SRSD with CS (45 patients)
    • SRSD without CS (45 patients)
  • PE Group: 29 patients with exposed pulps during treatment.

Key Findings

After five years:

  • Success Rates: SRSD (94.1-100%) was significantly more successful than SRFD (75.8%) and PE (81.8%).
  • Factors Influencing Outcomes: Cavity type and depth affected dentin bridge formation.

Conclusion

The study concluded that SRSD, with or without CS, is more effective than SRFD for treating deep caries, regardless of patient age or cavity characteristics. Using CS after SRSD improved healing.

Clinical Relevance

SRSD is a better option for managing deep caries lesions.
