Summary
Direct pulp capping and partial pulpotomy show comparable success rates for treating carious pulp exposures in permanent teeth with reversible pulpitis, offering effective pain relief and long-term preservation of pulp vitality.
Area of Science:
- Endodontics
- Restorative Dentistry
- Dental Traumatology
Background:
- Vital pulp therapy aims to maintain pulp vitality in carious exposures.
- Lack of clear guidelines for selecting direct pulp capping versus partial pulpotomy exists.
- Reversible pulpitis is a key diagnostic indicator for vital pulp therapy selection.
Purpose of the Study:
- To compare the clinical and radiographic outcomes of direct pulp capping and partial pulpotomy.
- To evaluate the success rates of these vital pulp therapy procedures.
- To determine the optimal treatment for carious pulp exposures with reversible pulpitis.
Main Methods:
- A parallel, double-blind, randomized clinical trial involving 140 mature permanent teeth.
- Teeth with reversible pulpitis were randomized to direct pulp capping (n=67) or partial pulpotomy (n=73).
- NeoPUTTY was used as the capping material; outcomes assessed at 6 and 12 months post-operatively.
Main Results:
- Both treatments significantly reduced pain within 1 week.
- At 1 year, success rates were 91.5% for partial pulpotomy and 81.3% for direct pulp capping (P = .08).
- No significant prognostic factors or interactions were identified for either procedure.
Conclusions:
- Direct pulp capping and partial pulpotomy are successful vital pulp therapy options for carious exposures in teeth with reversible pulpitis.
- Treatment selection should be based on intraoperative assessment of the exposed pulp.
- Both procedures effectively manage pain and preserve pulp vitality.
