ABSTRACT
Abstract This study aimed to evaluate sodium hypochlorite (NaOCl), limewater (LW), and Polymyxin B (PMB) as irrigants over MMP-3, MMP-8 and MMP-9. Thirty-three patients with apical periodontitis of single-rooted teeth were treated according to three-experimental groups (n=11) group-1 2.5% NaOCl was used as irrigant; group-2 2.5% NaOCl for the first two files and LW [0.14% Ca(OH)2] for the last two files; group-3 2.5% NaOCl for the first two files and PMB for the last two files. The association of Ca(OH)2 and CHX was used as an intracanal medication in all groups. Four root canal samplings (S) were collected S1) immediately after access cavity; S2) after biomechanical preparation; S3) after EDTA application; and S4) after removal of the intracanal medication. After quantification of MMP-3, MMP-8, and MMP-9, the data were analyzed by Friedman and Kruskal-Wallis tests and completed by Dunn test (5%). Regardless the used irrigant, there was no difference in reducing MMP-3 or MMP-8 (P=0,5273, P=0,7048 respectively). However, in reducing MMP-9 (P=0,0246) the NaOCl group was the most effective followed by NaOCl+LW group and NaOCl+PMB group respectively. The intracanal medication [Ca(OH)2 + CHX] with the NaOCl and NaOCl+LW was effective in reducing MMP-8 (P<0,0001, P=0,0025) and MMP-9 (P=0,0007, P=0,0047) respectively, but not for the group of NaOCl+PMB which was not effective in reducing MMP-8 or MMP-9 (P=0,1718, P=0,1953) respectively. NaOCl and NaOCl+LW were effective in reducing MMP-9 levels, and this effectivity could be improved by the use of the intracanal medication [Ca(OH)2 + CHX] in reducing MMP-8 and MMP-9 levels.
RESUMO
Resumo O objetivo deste estudo foi avaliar o hipoclorito de sódio (NaOCl), água de cal (LW) e polimixina B (PMB) como soluções irrigadoras sobre MMP-3, MMP-8 e MMP-9. Trinta e três pacientes com periodontite apical de dentes unirradiculares foram tratados de acordo com três grupos experimentais (n= 11) grupo 1 2,5% NaOCl foi usado como solução irrigadora; grupo-2 NaOCl a 2,5% para as duas primeiras limas e LW [0,14% Ca(OH)2] para as duas últimas limas; group-3 2.5% NaOCl para as duas primeiras limas e PMB para as duas últimas limas. A associação de Ca(OH)2 e CHX foi utilizada como medicação intracanal em todos os grupos. Quatro amostras de canais radiculares (S) foram coletadas S1) imediatamente após a cirurgia de acesso; S2) após o preparo biomecânico; S3) após aplicação do EDTA; e S4) após a remoção da medicação intracanal. Após a quantificação das MMP-3, MMP-8 e MMP-9, os dados foram analisados pelos testes de Friedman e Kruskal-Wallis e completados pelo teste de Dunn (5%). Independentemente da solução irrigadora utilizada, não houve diferença na redução de MMP-3 ou MMP-8 (P= 0,5273, P= 0,7048 respectivamente). No entanto, na redução de MMP-9 (P= 0,0246) o grupo NaOCl foi o mais eficaz, seguido pelo grupo NaOCl+LW e grupo NaOCl+PMB, respectivamente. A medicação intracanal [Ca(OH)2 + CHX] com o NaOCl e NaOCl+LW foi eficaz na redução de MMP-8 (P<0,0001, P= 0,0025) e MMP-9 (P= 0,0007, P= 0,0047) respectivamente, mas não para o grupo de NaOCl+PMB que não foi eficaz na redução de MMP-8 ou MMP-9 (P= 0,1718, P= 0,1953), respectivamente. NaOCl e NaOCl+LW foram eficazes na redução dos níveis de MMP-9, e esta efetividade pode ser melhorada pelo uso da medicação intracanal [Ca(OH)2+CHX] na redução dos níveis de MMP-8 e MMP-9.
