Resumen
Los microorganimos intraradiculares en pulpas necróticas fueron los principales causales de patologías Periapicales, si no son eliminados después de la biomecánica y medicación intraconducto, se pudo tener la seguridad que nuestro tratamiento endodóntico está predispuesto a fracasar, para esto fue necesario saber cuáles fueron los microorganismos que existieron en ese conducto radicular, considerando las características de la pieza dentaria a tratar independientemente. El objetivo de la presente investigación fue determinar la microbiota presente en pulpas necróticas con lesión periapical pre y post a la instrumentación biomecánica en conductos uniradiculares periodo 2014-2015 Clínica integral del adulto Universidad de Guayaquil Facultad Piloto de Odontología. Para poder realizar de manera satisfactoria la identificación de la microbiota pulpar , se debió cumplir a cabalidad la toma de la muestra, ya que un solo error pudo generar resultados negativos o alteraciones en los mismos , siendo así en el presente estudio se realizó el diagnostico por medio de cultivos bacteriológicos trasladados inmediatamente al laboratorio clínico .Esta investigación fue de tipo experimental y descriptiva, por la identificación y análisis de la microbiota existente pre y post instrumentación, Y experimental porque las variables fueron evidenciadas en dos casos clínicos realizados en la Universidad de Guayaquil Facultad Piloto de Odontología Clínica integral del Adulto .En esta investigación se pudo observar que los microorganismos más comunes en pulpas necróticas con lesión periapical fueron los microorganismos anaerobios como el Fusobacterium nucleatum ,Porfiromonas Asaccharolytica, por lo tanto se recomienda el uso del hidróxido de calcio ya que gracias a su poder bactericida que ejerce sobre estos microorganismos, facilitando así su erradicación siendo favorable para el tratamiento endodóntico y posterior desaparición de la lesión periapical producto de la existencia de los mismos. Palabra clave: pulpas necróticas, lesión periapical, terapia endodóntica, microbiología endodóntica.
The intraradicular microorganisms in necrotic pulps were the main causes of periapical pathologies, if not eliminated after biomechanics and intracanal medication, it could be assured that our endodontic treatment is predisposed to fail, for it was necessary to know what microorganisms were that They existed in the root canal, considering the characteristics of the tooth to be treated independently. The objective of this research was to determine the microbiota present in necrotic pulps with pre and post injury biomechanics periapical instrumentation channels uniradiculares period 2014-2015 adult comprehensive Clinic University of Guayaquil School of Dentistry Pilot. To perform satisfactorily identify the microbiota pulp was due to fully comply the sampling, because a single mistake could lead to negative results or alter them, so being in the present study the diagnosis was made by bacteriological cultures through immediately transferred to the clinical laboratory .This research was experimental and descriptive, for the identification and analysis of existing microbiota pre and post instrumentation and experimental because the variables were evidenced in two clinical cases performed at the University of Guayaquil Pilot School Adult Comprehensive Dentistry Clinic .In this study it was observed that the most common microorganisms in necrotic pulps with periapical lesion were anaerobes Fusobacterium nucleatum like, Porphyromonas asaccharolytica therefore the use of calcium hydroxide is recommended as thanks to its bactericidal power exercised over these organisms, thereby facilitating their eradication to be favorable for root canal treatment and subsequent disappearance of the lesion periapical product of the existence thereof. Keyword: necrotic pulp, periapical lesion, endodontic therapy, endodontic microbiology.
