 es Microbiología pulpar de dientes íntegros con lesiones apicales de origen idiopático
Rodríguez, Patricia & Calero, Jesús Alberto

Resumen

Introducción: Los cambios periapicales denominados lesiones, en dientes con integridad coronal completa y sin antecedentes de trauma, no presentan una etiología clara.
Objetivo: Determinar la presencia de microorganismos en el tejido pulpar clarifica las causas de su muerte y el consiguiente daño a los tejidos periodontales
Materiales y métodos: Se seleccionaron 23 dientes, en personaas con rangos de edad entre 10 y 39 años. Las muestras se tomaron con puntas de papel y limas N° 0.8 (estériles), se transportaron en VMGA III, se procesaron en las siguientes 24 horas de tomada la muestra y se sembraron en agar brucella.
Resultados: Los dientes más afectados fueron los centrales superiores 43.8%. De los 23 dientes estudiados, en 20 se observó crecimiento microbiológico. Se identificaron los siguientes microorganismos: Fusobacterium check for this species in other resources spp., 25%; Eubacterium check for this species in other resources spp., 15%; Peptostreptococcus check for this species in other resources spp., 10%; Campylobacter check for this species in other resources spp., 10%; bacilos entéricos gram negativos, 10%; Porphyromonas gingivalis, 10%; Prevotella intermedia, 5%; Eikenellia corrodens, 5%; Dialister pneumosintes, 5%; y levaduras en 5%. No hubo evidencias de crecimiento de Actinomyces actinomycetemcomitans, Tanerella forsythensis ni de estreptococo β hemolítico.
Discusión y conclusiones: El tejido pulpar sano es estéril, la lesión sobre él causa inflamación degeneración, muerte pulpar y contaminación bacteriana. Los resultados en el presente estudio determinaron claramente la presencia de micro-organismos en lesiones apicales cerradas de origen endodóntico. De igual forma se evidencia que gran parte de los microorganismos que se encontraron son considerados periodontopatógenos lo que puede igualmente sugerir manejo compartido entre tratamiento endodóntico, periodontal y farmacológico.

 en Pulp microbiology of complete teeth with idiopathic apical lesions
Rodríguez, Patricia & Calero, Jesús Alberto

Abstract

Introduction: Periapical changes named as lesions, in teeth with full crown integrity and without history of trauma, do not show a clear aetiology.
Objective: To determine the presence of microorganisms in pulp dental tissue will clarify the cause of its death and therefore the damage to periodontal tissues.
Materials and methods: From people between 10 and 39 years old, 23 teeth were selected. The samples were taken with paper points and 0.8 sterile files, and were transported in VMGA III medium, to be processed in the following 24 hours after they were taken and sowed in Brucella-agar.
Results: The most affected teeth were upper central incisors, 43.8%. From the 23 studied teeth, microbiological grow was seen on 20 teeth. The following microorganisms species were identified: Fusobacterium check for this species in other resources spp., 25%, Eubacterium check for this species in other resources spp., 15%; Peptostreptococcus check for this species in other resources spp., 10%; Campylobacter check for this species in other resources spp., 10%; gram negative enteric bacteria, 10%; Porphyromonas gingivalis, 10%; Prevotella intermedia, 5%; Eikenellia corrodens, 5%; Dialister pneumosintes, 5%; and yeasts, 5%. There was no growing evidence of Actinomyces actinomycetemcomitans, Tanerella forsythensis and Streptococcus ß hemolytic.
Discussion and conclusions: Sound pulp dental tissue is sterile; an injury over it will cause its inflammation, degeneration, death and bacterial contamination. Results in the present study clearly show the presence of microorganisms in closed apical dental lesions of endodontic origin. In same manner, it was seen that a great part of microorganisms species found can be regarded as periodontal pathogens. This could suggest a management with an endodontic, a periodontic and a pharmacological combined treatment.
