Summary
Direct pulp capping using calcium hydroxide shows high long-term success rates in mature teeth. Maintaining a quality coronal restoration is crucial for successful direct pulp capping outcomes.
Area of Science:
- Dentistry
- Endodontics
- Dental Materials
Background:
- Direct pulp capping is a dental procedure to preserve pulp vitality.
- This study focuses on the long-term outcomes of direct pulp capping in mature teeth.
Purpose of the Study:
- To evaluate the long-term success rate of direct pulp capping in mature teeth.
- To identify factors influencing the outcome of direct pulp capping procedures.
Main Methods:
- Retrospective evaluation of 225 teeth treated over 15 years by a single operator.
- Direct pulp capping with calcium hydroxide or calcium hydroxide-based cement for teeth with pulp exposure and reversible pulpitis.
- Long-term follow-up (1 to >35 years) assessing success based on clinical and radiographic criteria.
Main Results:
- Success rates were 100% at 1 year, decreasing to 89% at 35 years.
- The quality of the coronal restoration was the most significant factor affecting treatment outcome (P < .001).
- Exposure size, capping material, and restoration type also influenced outcomes at later follow-up periods.
Conclusions:
- Direct pulp capping with calcium hydroxide demonstrates a high success rate, particularly in the first decade.
- The integrity and quality of the coronal restoration are paramount for the long-term success of direct pulp capping.
