Summary
Regenerative endodontic procedures (REP) successfully treated a young patient with dens invaginatus and apical periodontitis. This approach promoted hard tissue formation and complete healing, demonstrating REP's potential for compromised teeth.
Area of Science:
- Endodontics
- Regenerative Endodontics
- Dental Traumatology
Background:
- Case report on a 16-year-old male with Oehlers type II dens invaginatus affecting tooth #10.
- Diagnosis included asymptomatic apical periodontitis despite prior treatment.
- The tooth presented structural compromise necessitating advanced endodontic intervention.
Purpose of the Study:
- To present the treatment of a structurally compromised maxillary lateral incisor using regenerative endodontic procedures (REP).
- To evaluate the outcomes of REP in a case of dens invaginatus with apical periodontitis.
- To investigate hard tissue formation within the root canal following REP.
Main Methods:
- Regenerative endodontic procedure (REP) performed on tooth #10.
- Procedure complicated by apical displacement of mineral trioxide aggregate (MTA).
- Yearly clinical and radiographic examinations, including cone-beam computed tomography (CBCT), were conducted. Tooth was re-accessed and root-filled with MTA.
Main Results:
- Complete periapical healing achieved 3 years post-REP.
- Significant thickening of dentinal root walls and completed apex formation observed.
- Hard tissue formation noted within the root canal, on canal walls, and at the apex via clinical, radiographic, and CBCT assessment.
- Reduced hard tissue formation on the labial wall adjacent to the displaced MTA.
Conclusions:
- Regenerative endodontic procedures (REP) can yield excellent outcomes for structurally compromised teeth.
- REP should be considered a primary treatment option for immature teeth with incomplete root development.
- Meticulous technical execution is crucial for successful REP outcomes, especially in cases with complications like MTA displacement.
