Adjunctive SAF Infinitum With Continuous NaOCl/HEDP Chelation Reduces Hard-Tissue Debris in Flattened Canals After...

Area of Science:

• Endodontics
• Dental Materials Science
• Biomaterials

Background:

• Effective removal of hard-tissue debris (HTD) is crucial for successful root canal treatment.
• Flattened root canal anatomy presents challenges for thorough cleaning and debris elimination.
• Single-file instrumentation systems aim to simplify root canal preparation but may leave residual debris.

Purpose of the Study:

• To evaluate the effectiveness of the adjunctive SAF Infinitum procedure in reducing HTD.
• To compare debris removal efficacy after single-file preparation with Reciproc Blue or XP-endo Rise Shaper.
• To assess the impact of continuous chelation irrigation during the SAF Infinitum procedure.

Main Methods:

• Thirty mandibular incisors with flattened canals were prepared using Reciproc Blue R25 or XP-endo Rise Shaper.
• Irrigation utilized 2.5% sodium hypochlorite (NaOCl) with etidronic acid (HEDP).
• Micro-computed tomography (micro-CT) scans assessed canal morphology and HTD before and after preparation and SAF instrumentation.

Main Results:

• No significant difference in baseline morphology or post-preparation HTD between the two shaping groups.
• The adjunctive SAF Infinitum procedure significantly reduced HTD in both preparation groups.
• Final residual HTD volumes were comparable between protocols, but percentage reduction was higher with Reciproc Blue.

Conclusions:

• Adjunctive SAF Infinitum procedure with continuous chelation enhances hard-tissue debris removal in flattened root canals.
• This benefit is achieved irrespective of the initial single-file instrumentation system employed.
• The SAF Infinitum system offers a valuable adjunct for improving canal cleanliness in challenging anatomies.
