Endodontic access to maxillary lateral incisors

|October 1, 1981
Summary
For maxillary lateral incisors, the ideal endodontic access opening should be slightly buccal to the incisal edge. This ensures the most direct path for canal débridement, potentially improving endodontic therapy success rates.
Area of Science:
- Endodontic Therapy
- Dental Anatomy
- Radiographic Analysis
Background:
- Accurate root canal débridement is crucial for successful endodontic therapy.
- The orientation of the occlusal access opening influences the directness of the path to the root canal's long axis.
Purpose of the Study:
- To determine the optimal location for occlusal access openings in maxillary lateral incisors for endodontic treatment.
- To analyze the projection of buccal and lingual walls onto the incisal edge of maxillary lateral incisors.
Main Methods:
- Radiographic examination of 131 maxillary lateral incisors from a mesiodistal perspective.
- Analysis of projections of buccal and lingual walls relative to the incisal edge.
Main Results:
- 16% of projections opened buccally to the incisal edge.
- 32.9% were buccal and inclusive of the incisal edge.
- 43.5% were buccal and lingual to the incisal edge.
- 6.9% were inclusive of the lingual to the incisal edge.
- 0.8% were entirely lingual to the incisal edge.
Conclusions:
- The ideal occlusal access opening for maxillary lateral incisors should be inclusive of and slightly buccal to the incisal edge.
- This positioning facilitates a more direct path to the root canal's long axis.
- Optimizing access opening location can enhance the efficacy of canal débridement in endodontic procedures.
