The cervical window as an aid in root canal access

Area of Science:

• Dentistry
• Endodontics
• Dental Anatomy

Background:

• Cervical caries, both treated and untreated, can obstruct direct access to the coronal opening of root canals.
• Standard endodontic access may be compromised by the location and extent of cervical decay.
• Difficulty in accessing the canal system can lead to incomplete treatment and potential complications.

Observation:

• A direct visualization approach through a surgically created buccal opening, termed a 'buccal window', was employed.
• This technique was successfully utilized in two clinical cases presenting with challenging root canal access due to cervical caries.
• The buccal window provided an unobstructed pathway to the coronal aspect of the root canal system.

Findings:

• The buccal window technique facilitates direct visual access to the coronal root canal opening, even in the presence of significant cervical caries.
• This method overcomes the limitations of traditional access preparations when faced with restorative or carious challenges at the cervical level.
• Successful application in two patients demonstrates the feasibility and efficacy of this approach.

Implications:

• The buccal window technique presents a viable alternative for endodontic access in complex cases involving cervical caries.
• This approach may enhance the predictability and thoroughness of root canal treatment in compromised dentition.
• Further investigation and case studies are warranted to establish the broader applicability and long-term outcomes of the buccal window technique in endodontic therapy.
