Scanning electron microscopy analysis of RinsEndo system and conventional irrigation for debris removal

Abstract

A new device for irrigation, which presents hydrodynamic activation based on the pressure-suction technology, has recently been introduced to the market: the RinsEndo system. This study compared the efficacy of the RinsEndo system and conventional (manual-dynamic) irrigation in the removal of debris from the root canal walls, using scanning electron microscopy (SEM). Twenty mandibular premolars with completely formed roots were selected and randomly divided into group 1 (irrigation with the RinsEndo system) and group 2 (conventional irrigation). The canals were irrigated with 1 mL of saline at each change of instrument. Instrumentation started with a #15 K file and continued up to a #40 K file, which was standardized as the working length instrument. Then, the teeth were sectioned in buccolingual direction and the halves were sputter-coated with gold and examined by SEM. The apical, middle and cervical root canal thirds were evaluated, and the results were analyzed statistically by the Mann-Whitney test for comparison between methods, Kruskal-Wallis test for comparison among thirds, and Miller test for individual comparisons. A significance level of 5% was set for all analyses. The results did not show significant differences (p>0.05) between methods at each third and among thirds for each technique analyzed individually. In conclusion, there was no difference in the cleaning ability of the RinsEndo system and conventional irrigation.

Debris and smear removal in flattened root canals after use of different irrigant agitation protocols

“…This result is in agreement with those of studies that used similar SEM analysis (Hü lsmann et al, 1997; Salman et al, 2010;Vivan et al, 2010) or optical microscopy (Ferreira et al, 2004;Fornari et al, 2010;Nadalin et al, 2009;Passarinho-Neto et al, 2006), and found debris in flattened areas of the canals that were not reached by the endodontic instruments. However, among the irrigation/activation protocols evaluated in the present study, those using ultrasonic and apical negative pressure irrigation (EndoVac system) were more effective for removal of debris.…”

In vitro Evaluation of the Effect of Sonic Vibration on the Cleaning Capability of Root Canal Irrigants

“…[35][36][37] In contrast, a comparison of the RinsEndo, a device for automatic irrigation, with conventional cleaning using a syringe found no significant difference in cleaning capability. 38) Dynamic cleaning has also been reported to increase the chemical permeability of dentin. 39) In the former, sodium hypochlorite solution and EDTA were used as the irrigants, whereas the irrigant solutions used in the latter, were sodium hypochlorite solution or …”

“…25 Yapılan başka bir araştırmada ise; kök kanallarındaki dentin debrisini uzaklaştırma etkinliği bakımından, RinsEndo ve konvensiyonel irrigasyon sistemleri arasında fark olmadığı bildirilmiştir. 48 EndoVac sistemi, endodontik irrigasyon yöntemlerinde, en son gelişim gösteren sistemlerden birisidir. Bu sistem sayesinde; kanaldaki tüm çalışma aralığının,sürekli gelen sıvı yardımı ile yıkanması sağlanır.…”
