Resumen
La irrigación en endodoncia tiene como finalidad eliminar
microorganismos que permanezcan en el conducto, en los túbulos
dentinarios y mantener las paredes dentinarias hidratadas y lubricadas.
Existen varias soluciones propuestas como irrigante endodóntico, a si
mismo ninguna de estas posee todas las propiedades requeridas para
cumplir con un buen protocolo de irrigación. Por lo que reconocemos a la
clorhexidina como un agente eficaz antimicrobiano oral utilizado en el
tratamiento periodontal, en la prevención de caries y en las infecciones
orales en general. Así mismo señalamos el potencial de la clorhexidina
cuando es aplicada como solución de irrigación o medicamento durante el
tratamiento endodóntico, teniendo más ventaja su poder antimicrobiano.
Definimos a la clorhexidina como una molécula catiónica simétrica que
consta de dos anillos de 4-clorofenil y dos grupos biguánidos unidos por
un anillo central de hexametileno. Algunos estudios clínicos han
demostrado que no existe un aumento significativo de la resistencia
bacteriana ni desarrollo de infecciones oportunistas durante el tratamiento
a largo plazo con clorhexidina.
En endodoncia la usamos al 2% como una solución irrigadora para lavar
conductos radiculares en casos de tratamientos y retratamientos, ápices
abiertos, alergia al hipoclorito de sodio o como vehículo acuoso con
hidróxido de calcio. Los efectos adversos de este medicamento son, en
general, leves y transitorios en especial manchas pardas en los dientes, la
lengua, prótesis y restauraciones de silicato y resina, así como la
alteración pasajera de la percepción gustativa y descamación de la
mucosa oral.
Irrigation in endodontics is to eliminate microorganisms remaining in the canal, in the dentinal tubules and dentin walls keep hydrated and lubricated. There are several solutions proposed as endodontic irrigant, himself none of these has all the properties required to meet a good irrigation protocol. As we recognize chlorhexidine as an effective oral antimicrobial agent used in periodontal treatment in preventing tooth decay and oral infections in general. Also note the potential of chlorhexidine when applied as irrigation solution or medication during endodontic treatment, taking more advantage of its antimicrobial power. We define a symmetrical cationic chlorhexidine molecule consisting of two rings of 4-chlorophenyl and two biguanides groups joined by a central ring hexamethylene. Clinical studies have shown no significant increase in bacterial resistance or development of opportunistic infections during longterm treatment with chlorhexidine. In endodontics we use 2% as an irrigating solution in root canals washing treatment and retreatment cases, open apices, allergy or sodium hypochlorite aqueous vehicle with calcium hydroxide. Adverse effects of this drug are generally mild and transient in special brown spots on the teeth, tongue, prostheses and restorations silicate and resin, as well as the transient alteration of taste perception and scaling of the oral mucosa.
