Summary
Glutaraldehyde pulpotomy in primary molars showed high clinical success but lower radiographic success after 36 months. Clinicians should exercise caution with glutaraldehyde agents due to a notable failure rate.
Area of Science:
- Pediatric Dentistry
- Endodontics
- Dental Materials Science
Background:
- Pulpotomy is a common treatment for pulp-exposed primary molars.
- Glutaraldehyde is frequently used as a pulpotomy agent.
- Long-term clinical and radiographic outcomes of glutaraldehyde pulpotomy require further evaluation.
Purpose of the Study:
- To clinically and radiographically assess the long-term success rate of pulpotomy using different glutaraldehyde preparations in primary molars.
Main Methods:
- A 36-month follow-up study involving 258 primary molars in 201 children (4-7 years old).
- Four glutaraldehyde preparations were used: 2% buffered, 2% unbuffered, 5% buffered, and 5% unbuffered.
- Clinical and radiographic evaluations were performed on 150 teeth.
Main Results:
- Clinical success was high at 98%, but radiographic success was lower at 78.7% over 36 months.
- The 5% buffered glutaraldehyde group had the highest success rate (87.5%), while the 5% unbuffered group had the lowest (74.1%).
- No significant difference in success rates was found among the four glutaraldehyde groups. Canal obliteration occurred in 22 successfully treated teeth.
Conclusions:
- Long-term radiographic evaluation reveals a concerning failure rate for glutaraldehyde pulpotomy in primary molars.
- While clinical success appears high, radiographic evidence suggests potential long-term issues.
- Clinicians should be cautious regarding the extensive use of glutaraldehyde as a pulpotomy agent.
