Summary
Calcium hydroxide and iodoform paste (Metapex®) effectively promoted root-end growth and apexification in nonvital immature permanent teeth. This treatment showed promising results in pediatric dental cases after 12 months.
Area of Science:
- Pediatric Dentistry
- Endodontics
- Regenerative Endodontics
Background:
- Immature permanent teeth with necrotic pulps present a challenge in pediatric dentistry.
- Apexification is crucial for maintaining the integrity and function of these teeth.
- Nonvital immature teeth require treatments that promote root development and apical closure.
Observation:
- Three pediatric cases of nonvital immature permanent teeth were treated.
- Calcium hydroxide and iodoform paste (Metapex®) was placed in the root canals.
- Radiographic evaluations were conducted over 12 months.
Findings:
- Metapex® demonstrated promising results in inducing root-end growth and apical closure (apexification).
- All treated teeth showed continued root development and no signs of periapical pathology after 12 months.
- Conventional endodontic treatment was successfully completed post-apexification.
Implications:
- This case series suggests Metapex® as a viable treatment option for apexification in pediatric patients.
- The use of calcium hydroxide and iodoform paste can lead to successful root development in immature teeth.
- Further research may validate Metapex® for broader application in regenerative endodontics.
