Resumen
Los irrigantes cumplen roles muy importantes en las terapias pulpares, como aumentar la desinfección y eliminación de las bacterias, facilitando a su vez la remoción de tejido necrótico como todo el tejido pulpar y dentinario que se encuentra en el conducto pulpar de forma infectada, garantizando la eliminación de dentina contaminada y la permeabilidad del conducto desde el orificio coronario hasta el agujero apical.
Los problemas asociados a la irrigación activa, es la resistencia o prevalencia bacteriana que se puede producir, ya sea por la técnica que se desarrolla o por los materiales que se utiliza para su desinfección.
Poder determinar mediante un estudio los irrigantes más efectivos para distintos procedimientos será muy útil para los odontólogos que ejercen como endodoncistas, disminuyendo el índice de resistencia bacteriana y por ende los fracasos endodónticos, E. fecalis forma parte normal de la flora microbiana humana y es predominante entre los microorganismos en dientes tratados endodónticamente con periodontitis apical persistente.
Las técnicas de irrigación se clasifican en dos tipos, las técnicas manuales y las técnicas asistidas por máquinas. En las técnicas manuales se describe a la técnica convencional la cual se fundamenta en el principio de la presión positiva, las desventajas son la imposibilidad de limpiar el tercio apical y la alta probabilidad de extrusión de la solución toxica que irrita el tejido perirradicular. La irrigación, acompañada de la aspiración, es un auxiliar en la instrumentación del conducto radicular, y tiene como objetivo la remoción de los detritos, la reducción del número de bacterias existentes en el interior de los conductos radiculares.
Palabras claves: Irrigación, desinfección, resistencia bacteriana, hipoclorito de sodio.
Irrigators perform very important roles in pulpal therapies, such as increasing the disinfection and elimination of bacteria, facilitating the removal of necrotic tissue as well as all the pulp and dentin tissue that is found in the infected pulp canal, Removal of contaminated dentin and the permeability of the canal from the coronary orifice to the apical foramen. The problems associated with active irrigation, is the resistance or bacterial prevalence that can occur, either by the technique that is developed or by the materials that are used for its disinfection. To be able to determine by means of a study the most effective irrigators for different procedures will be very useful for dentists who exercise as endodontists, decreasing bacterial resistance index and, consequently, endodontic failures, E. fecalis forms a normal part of the human microbial flora and is predominant Among microorganisms in endodontically treated teeth with persistent apical periodontitis. Irrigation techniques are classified into two types, manual techniques and machine assisted techniques. In manual techniques the conventional technique is described which is based on the principle of positive pressure, the disadvantages are the impossibility of cleaning the apical third and the high probability of extrusion of the toxic solution that irritates the periradicular tissue. Irrigation, accompanied by aspiration, is an aid in the instrumentation of the root canal, and aims to remove debris, reducing the number of bacteria existing inside the root canal.
