Summary
Calcium hydroxide apexification is a highly successful endodontic treatment for immature teeth with pulpal necrosis. This apexification method proved effective regardless of patient factors or clinical variables encountered during treatment.
Area of Science:
- Dentistry
- Endodontics
- Regenerative Endodontics
Background:
- Immature teeth with pulpal necrosis pose treatment challenges.
- Apexification aims to induce root-end closure in non-vital immature teeth.
- Calcium hydroxide is a common material used in apexification procedures.
Purpose of the Study:
- To evaluate the clinical and radiographic success of calcium hydroxide apexification.
- To identify factors influencing treatment time and outcomes in endodontic therapy for immature teeth.
Main Methods:
- Retrospective study of 48 patients undergoing calcium hydroxide apexification.
- Data collected included tooth characteristics, etiology, patient demographics, and treatment parameters.
- Clinical and radiographic success were assessed post-treatment.
Main Results:
- Apexification required an average of 1 year +/- 7 months.
- Presence of radiolucency and larger apex opening correlated with interappointment symptoms (p<0.04 and p<0.02, respectively).
- Interappointment symptoms delayed apexification by an average of 5 months.
Conclusions:
- Calcium hydroxide apexification demonstrates high clinical and radiographic success rates.
- Treatment success was not significantly affected by the clinical variables examined.
- Interappointment symptoms can prolong apexification treatment duration.
