Influence of irrigation needle type on apical cleaning efficacy in endodontic treatment - An in vivo study

The impact of various irrigation needles on apical cleaning during endodontic treatment was assessed in this <i>in vivo</i> investigation. The use of open-ended, side-vented or double-side vented needles determined the patients' grouping. Apical cleanliness was evaluated under a microscope after standard irrigation with sodium hypochlorite was completed. Open-ended needles performed the worst in terms of cleaning effectiveness, while double-side vented needles were the most effective. The findings imply that needle design has a major impact on the removal of apical debris and ought to be carefully taken into account in clinical practice.
