Title : Enhancing root canal success strategic use of orifice opener one step synthesis gels orifice barriers

Abstract:

Modern endodontics comprises of chemico-mechanical phases aimed at eliminating microorganisms to prevent apical periodontitis. According to Swartz et al., the failure rate of endodontically treated teeth is nearly double when adequate post-endodontic restoration is absent. The four key phases: access and mechanical preparation, chemical cleaning, filling, and endodontic sealing- each phase plays a critical role in ensuring successful outcomes.

Coronal flaring of root canals is a vital technique in contemporary cleaning and shaping procedures, as it enables unobstructed access and enhances the effectiveness of subsequent steps. Specialized nickel-titanium instruments, known as orifice openers or shapers, are designed with a conical shape to effectively widen the canal.

Silver NanoParticles (AgNPs), have gained interest in this context because they can penetrate hard-to-reach areas, such as dentinal tubules, effectively inhibit the growth of microorganisms like Enterococcus faecalis. Every effort should be made to prevent infectious contamination. To ensure long-term success, the use of one-step synthesis gels for enhanced disinfection is recommended.

The American Association of Endodontists emphasizes in a white paper that a definitive coronal restoration is an integral part of the root filling process to prevent recontamination of the pulp space. Roghanizad and Jones further advocate for placing a coronal seal at the orifice, recommending the replacement of 3 mm of coronal gutta-percha to enhance protection.

To ensure long-term success, the use of orifice openers for effective canal shaping, one-step synthesis gels for enhanced disinfection, and orifice barriers after final obturation should be strongly emphasized as critical techniques for preventing recontamination, apical periodontitis and for promoting durable outcomes.
