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.
