Aim To evaluate the efficacy of sonically and ultrasonically activated irrigation on removal of accumulated hard‐tissue debris (AHTD) in mesial root canal systems of mandibular molars using micro‐computed tomographic (micro‐CT) analysis. Methodology Forty mesial roots of mandibular molars with two independent canals joined apically by an isthmus (Vertucci type II) were selected. The root canals were instrumented using Reciproc R25 instruments, and specimens were scanned at a resolution of 10.5 μm. Subsequently, n = 10 roots were assigned to each of the four final irrigation groups such that the group means and variances were almost identical: sonically activated irrigation with EndoActivator (EA) or EDDY (ED), ultrasonically activated irrigation (UAI) and manual irrigation without activation (MI). The final irrigation procedures were performed using a total of 5 mL 1% NaOCl and 5 mL 15% EDTA per canal over 5 min with activation time of 4 × 20 s. Reconstructed data sets were coregistered, and the mean percentage reduction of AHTD after final irrigation was compared statistically between groups using analysis of variance at a significance level set at 5%. Results A significant reduction of AHTD was achieved after final irrigation in all groups (P < 0.05), ranging from 44.1% to 66.8%. The vol% of debris after irrigation was 3.7 ± 1.9% for EA, 3.3 ± 2.3% for ED, 2.1 ± 1.6% for UAI and 4.4 ± 2.3% for MI, with no significant difference between groups (P > 0.05). Conclusions None of the final irrigation protocols completely removed AHTD from mesial root canal systems in extracted human mandibular molars. Sonically and ultrasonically activated irrigation performed no better compared to manual irrigation.

“…Many other studies have also proven great effectiveness of RinsEndo, especially in rinsing the apical third of the canal (15,16). According to the studies so far, acoustic streaming and cavitation of the irrigant, created during the PUI, improve cleaning efficacy (25,27). One of the explanations of our results is the irrigation time.…”

“…Prijašnja istraživanja također su potvrdila učinkovitost tog sistema, posebice u ispiranju apikalne trećine kanala (15,16). Prema dosadašnjim istraživanjima, zvučno istraživanje i kavitacije u sredstvu za ispiranje tijekom PUI-ja pojačavaju učin-kovitost irigansa (25,27). Jedno od objašnjenja jest vrijeme ispiranja.…”

“…Actualmente el concepto de IUP ha sido cuestionado, algunos reportes indican que el contacto con la pared del conducto radicular ocurre frecuentemente 22 . Sin embargo, la literatura reporta que la IUP presenta buenos resultados para la desinfección de los conductos radiculares, la eliminación de medicación intraconducto, la eliminación del smear layer y barro dentinario [7][8][9][10][11][12][13][14]16,21,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] .…”

La limpieza del sistema de conductos radiculares constituye uno de los principales factores para determinar el éxito del tratamiento endodóntico. Por lo tanto, la irrigación complementaria a la instrumentación juega un papel fundamental en la eliminación de las bacterias, restos de dentina y materiales terapéuticos. Además, el método de irrigación es fundamental para garantizar la eficiencia en la limpieza del sistema de conductos radiculares, que puede realizarse manualmente con una jeringa y una aguja, también utilizando dispositivos específicos para esta finalidad, como el ultrasonido. El objetivo de este estudio fue realizar una revisión de literatura sobre el efecto del ultrasonido en la limpieza del sistema de conductos radiculares. Una búsqueda eletrónica fue realizada en las bases de datos PubMed, LILACS y Cochrane Library, con los términos: “passive ultrasonic irrigation”, “root canal” y “endodontic irrigation”. Los artículos fueron seleccionados a partir de los criterios de inclusión y exclusión. Se concluyó que la irrigación ultrasónica pasiva es eficaz en relación a la eliminación de bacterias, hidróxido de calcio, restos dentinarios y smear layer, utilizándose hipoclorito de sodio (NaOCl) como solución de irrigación, permitiendo así una optimización en la limpieza del sistema de conductos radiculares.

Intermittent or continuous ultrasonically activated irrigation: micro-computed tomographic evaluation of root canal system cleaning

Abstract: Root canal irrigation plays an important role in cleaning and disinfection of the RCS. Effective apical irrigation is an important procedure during root canal treatment. PUI and CMI (at 1 mm short) were effective in cleaning of the main and simulated lateral root canals.
