A method to minimize complications in endodontic access cavity preparation

Area of Science:

• Dentistry
• Endodontics
• Dental Education

Background:

• Endodontic-access cavity preparation is critical for successful root canal treatment.
• Operative errors during access cavity preparation can lead to complications like perforation.
• Standardized methods are needed to improve accuracy and reduce errors in dental procedures.

Purpose of the Study:

• To present and evaluate a novel line-drawing method for endodontic-access cavity preparation.
• To assess the effectiveness of the technique in reducing operative errors.
• To determine if the method improves the quality of access cavities prepared by dental students and residents.

Main Methods:

• A line is drawn on the crown's facial surface, representing the root canal's coronal two-thirds on a radiograph.
• This line guides bur angulation for pulp chamber entry, ensuring proper mesio-distal orientation.
• The method was evaluated by endodontic teachers using studies involving dental students and advanced education residents.

Main Results:

• The line-drawing method showed potential for facilitating more ideal endodontic access cavities compared to conventional methods.
• One study indicated a statistically significant difference (p < 0.045) between the control and test groups.
• All evaluations suggested a positive difference in cavity preparation quality when using the method.

Conclusions:

• The line-drawing technique is a valuable tool for teaching and practicing endodontic-access cavity preparation.
• The method may help reduce common operative errors such as gouging and perforation.
• Further research and testing are recommended to validate the clinical utility of this technique.
