Aim: To analyze the root canal organic tissue dissolution capacity promoted by irrigating solutions, with or without the use of different agitation techniques. Methods: Bovine pulp tissue fragments were initially weighed. The following irrigating solutions were tested: 2.5% sodium hypochlorite, 2% chlorhexidine digluconate solution, and distilled water. The irrigating protocols were: immersion, mechanical agitation with endodontic files, and ultrasonic or sonic systems (Endoactivactor® and Easy Clean®). At the end of the protocols, the pulps were weighed to determine their final weight. For comparison, the average percentage of tissue dissolution in relation to the groups was analyzed using the Kruskal-Wallis nonparametric test complemented by multiple comparisons test. The significance level was set at 5%. Results: Among the irrigation solutions, 2.5% sodium hypochlorite showed a higher dissolving power than 2% chlorhexidine digluconate and distilled water. Furthermore, ultrasonic and sonic systems were more effective irrigating protocols than immersion and mechanical agitation with endodontic files. Conclusions: The combination of sodium hypochlorite with an agitation system promotes a greater degree of tissue degradation.

“…As in our investigation, Koskinen et al (23), Gordon et al (24), Morgan et al (25), and Beltz et al (26) used bovine pulp to simulate human pulp; however, other kinds of tissue have been used to determine the efficacy of various root canal irrigants. Examples include human umbilical cord (27), porcine muscle (6,28), rat dermal connective tissue (4,29), pig palatal mucosa (30), and rabbit liver (2).…”

“…When these samples were blotted dry, it was noted that the tissue was firm; therefore, distilled water might function as a better control in future studies. Morgan et al (25) also reported that the use of saline as a control should be questioned. We agree with Morgan et al on this subject; however, Morgan et al found that isotonic saline dissolved a mean 10.48% of bovine pulp tissue.…”

ResumoIntrodução: O hipoclorito de sódio é a substância química auxiliar do tratamento endodôntico mais utilizada devido à sua ação antimicrobiana e à sua capacidade de dissolver matéria orgânica. Objetivo: O objetivo do presente estudo foi comparar a velocidade de dissolução de fragmentos de tecido pulpar bovino em diferentes concentrações de hipoclorito de sódio. Material e método: Fragmentos de tecido pulpar bovino, com peso determinado, foram imersos em 20 mL de hipoclorito de sódio, em frascos de Becker colocados em uma incubadora/agitadora. Foram testadas as concentrações de 1%, 2,5% e 5%, com pH 11, a 36°C. As amostras foram avaliadas visualmente durante a agitação, com auxílio de lupa, até sua completa dissolução. A velocidade de dissolução de cada fragmento foi determinada em miligramas por minuto e a velocidade média de cada grupo, analisada pelos métodos estatísticos de Kruskal-Wallis e Dunn's Multiple. Resultado: Houve diferença estatisticamente significante entre a concentração de 1%, que apresentou a menor velocidade, e as demais. Conclusão: A velocidade de dissolução do hipoclorito de sódio, nas concentrações testadas, se torna mais rápida com o aumento da concentração.Descritores: Hipoclorito de sódio; dissolução; polpa dentária. AbstractIntroduction: sodium hypochlorite is the most used auxiliary chemical substance in endodontic treatment due to its antimicrobial action and its ability to dissolve organic matter. Objective: the objective of the present study was to compare the dissolution speed of bovine pulp tissue fragments in different concentrations of sodium hypochlorite. Material and method: bovine pulp tissue fragments, with determined weight, were immersed in Becker bottles filled with 20 ml of sodium hypochlorite and placed in an incubator/stirrer. Concentrations of 1%, 2.5% and 5%, with pH of 11, at 36°C. Each sample was evaluated visually during the stirring, with the aid of magnifying glass, until its complete dissolution. The speed of dissolution of each fragment was determined in milligrams per minute and by the average speed of each group was analyzed by Kruskal-Wallis and Dunn's Multiple statistical methods. Result: There were statistically significant differences between the concentration of 1%, with the lowest speed, and others. Conclusion: The dissolution speed of sodium hypochlorite of tested concentrations, becomes faster with the increasing of the concentration.Descriptors: Sodium hypochlorite; dissolution; dental pulp.
