Concept of predictable disinfection in endodontics

Area of Science:

• Dentistry
• Endodontics
• Microbiology

Background:

• The timing of root canal obturation is critical for successful treatment outcomes.
• Factors such as patient symptoms, pulp vitality, and periradicular health influence obturation timing.
• Current endodontic practices consider single-visit procedures for specific clinical scenarios.

Purpose of the Study:

• To review the factors influencing the decision to obturate a tooth in endodontic treatment.
• To discuss the indications and contraindications for one-step versus multi-step obturation procedures.
• To highlight the importance of aseptic technique and bacterial control in root canal therapy.

Main Methods:

• Literature review of endodontic treatment protocols.
• Analysis of clinical factors affecting obturation timing.
• Discussion of outcomes based on pulp and periradicular status.

Main Results:

• One-step obturation is considered acceptable for vital pulp cases performed under aseptic conditions.
• Delayed obturation is generally indicated for teeth with acute symptoms, pulp necrosis, and periradicular abscesses.
• Antimicrobial dressings are often used between appointments for symptomatic cases prior to definitive obturation.

Conclusions:

• The clinical presentation of the patient, particularly pulp and periradicular status, dictates the optimal timing for obturation.
• Minimizing bacterial contamination through aseptic technique and timely obturation is key to endodontic success.
• Aseptic conditions and appropriate management of symptomatic teeth contribute to favorable treatment outcomes.
