Modern molar endodontic access and directed dentin conservation.

Area of Science:

• Dentistry
• Endodontics
• Restorative Dentistry

Background:

• Endodontically treated teeth can fail due to structural compromise rather than apical lesions.
• Current endodontic treatment models may not ensure long-term success.
• Traditional endodontic access approaches are considered fundamentally flawed.

Purpose of the Study:

• To critically evaluate molar access and failures in endodontically treated teeth.
• To propose a new set of criteria for guiding clinical treatment decisions.
• To enhance the long-term functionality and prognosis assessment of endodontically treated teeth.

Main Methods:

• Review of existing literature on endodontic treatment failures.
• Analysis of structural compromises in endodontically treated molars.
• Development of a decision-making framework for clinicians.

Main Results:

• Failures are often linked to structural compromises, not solely apical pathosis.
• Traditional access methods can weaken teeth, leading to non-restorable conditions.
• The proposed criteria aim to improve treatment planning and outcome prediction.

Conclusions:

• A revised approach to endodontic access is necessary for long-term tooth survival.
• Clinicians must consider structural integrity alongside biological factors.
• Implementing new criteria can help optimize treatment decisions and patient outcomes.
