Resumen
La presente investigación trata de la “valoración Invitro de la
penetración de la solución irrigadora mediante la utilización de agujas
hipodérmicas calibre 22G y 30G, aguja de tuberculina y aguja
endodóntica calibre 30G” La importancia de la irrigación del sistema de
conductos radiculares, radica en los beneficios que tienen las sustancias
irrigadoras en su limpieza y desinfección (14) Por lo general, el tercio
coronal del conducto radicular es adecuadamente desinfectado por
medios químicos – mecánicos usuales. El tercio apical del sistema de
conductos radiculares es particularmente difícil de limpiar debido a su
anatomía compleja, deltas apicales, istmos estrechos y canales laterales
(6,7) Además, el tercio apical es inadecuadamente alcanzado por las
sustancias irrigadoras debido a la incapacidad que tienen algunas agujas
para irrigar este tercio. Por tal motivo, la efectividad de la irrigación en el
tercio apical es particularmente dudoso (15). Es por esto que el Calibre de
la Aguja juega un papel muy importante durante la irrigación del sistema
de conductos. Las agujas de menor calibre pueden alcanzar el ápice
libremente sin pegarse a las paredes. Por lo tanto se debería de emplear
esta clase de agujas debido a que tienen una mejor manera en cuanto a la
remoción de partículas de ápice que es lo que demanda nuestra mayor
atención. En conductos curvos, una aguja flexible de 30 G debería
emplearse para negociar curvas no muy acentuadas para que la punta de
la aguja esté más cerca del ápice para una mejor irrigación. Los
resultados demostraron que las agujas que alcanzaron una mayor
penetración dentro del conducto fueron la de los calibres de 30 G y las
agujas endodónticas. Por tal motivo, la sustancia irrigadora que llego al
tercio apical fue aquella transportada por estas mismas agujas.
This research is the " valuation of Invitro penetration of the irrigating solution using needles 22G and 30G hypodermic needle and needle tuberculin endodontic gauge 30G " The importance of irrigation system Root canal lies in the benefits that the substances irrigating in cleaning and disinfection ( 14 ) Generally , the third coronal root canal is adequately disinfected by chemical means - mechanical usual . The system apical root canals is particularly difficult to clean because of their complex anatomy , apical deltas, isthmuses and narrow side channels (6.7 ) In addition , the apical third is inadequately reached by the irrigants due to the inability of some needles irrigate this third . Therefore, the effectiveness of irrigation in the apical third is particularly doubtful ( 15). That is why the gauge Needle plays an important role in irrigation system duct . The smaller gauge needles can reach the apex freely without sticking to the walls. Therefore should employ this kind of needles because they have a better way as to particle removal whit what they demand our greatest attention. In curved canals , a flexible 30-gauge needle should not used to negotiate sharp curves so that the tip of the needle is closer to the apex for better irrigation. the Results showed that the needles reaching greater penetration into the duct were calibers and 30G endodontic needles. Therefore, the substance that came to irrigating apical third was that carried by the same needle.
