RESUMEN. Antecedentes: existe evidencia clinica y experimental que la proteina C reactiva (PCR) es un marcador de inflamacion sistemica asociado a periodontitis cronica, siendo esta enfermedad la principal causa de edentulismo. Objetivo: identificar microorganismos periodontopatogenos presentes en pacientes edentulos y en pacientes con periodontitis moderada/avanzada y establecer su relacion con la proteina C reactiva ultrasensible (PCR-us). Metodos: estudio de corte transversal en 61 pacientes mayores de 30 anos divididos en dos grupos: con periodontitis cronica y edentulos, A cada paciente se le tomo una muestra de saliva y del dorso de la lengua para identificacion microbiologica de microorganismos y muestra serica para evaluacion de PCR-us. La asociacion microorganismo, PCR-us, grupo paciente. Resultados: PCR-us mostro un valor maximo de 1,12 mg/l en el grupo de edentulos sin ninguna diferencia estadisticamente significativa con el grupo de periodontitis cronica (p=0,29); sin embargo, valores mayores de PCR-us se observaron en pacientes con microorganismos como Candida albicans, Porphiromona gingivalis, Actinomyces naeslundii (A. naeslundii), Capnocytophaga sp, Streptococcus intermedius (S. intermedius), y Bacteroides thetaiotaomicron. Conclusion: De acuerdo con los resultados de este estudio, no hay diferencia en PCR-us entre pacientes edentulos y aquellos con enfermedad periodontal. Se encontraron periodontopatogenos en edentulos principalmente Capnocytophaga sp, A. naeslundii y S. intermedius, tanto en lengua como en saliva. ABSTRACT. Background: There is clinical and experimental evidence that the C-reactive protein (CRP) is a marker of systemic inflammation associated with chronic periodontitis, being this oral disease the main cause of edentulism, and sharing in some cases, some microorganisms. Purpose: To identify periodontal pathogens in edentulous and moderate/severe periodontitis subjects, and stablish its association with us-CRP. Methods: Cross sectional study in 61 patients older than 30 years old, divided in two groups: The edentulous group and the other with chronic periodontitis. A sample of saliva and tongue dorsum surface was collected for microbiological identification, and serum us-CRP levels were also evaluated. An association between the microorganisms and the us-CRP in each group of patients was investigated. Results: us-CRP showed a maximum level of 1.12 mg/l in the edentulous group with no statistically significant difference when was compared with the periodontitis group. However, the presence of microorganisms such as Candida albicans, Porphiromona gingivalis, Actinomyces naeslundii (A. naeslundii), Capnocytophaga sp, Streptococcus intermedius (S. intermedius), and Bacteroides thetaiotaomicron was associated to a slight increase in the serum us-CRP levels. Conclusion: According to the results of this study, there´s no difference in us-CPR between edentulous patients and those with periodontal disease. We found periodontopathogens in edentulous mainly Capnocytophaga sp, A. naeslundii, and S. intermedius in tongue and saliva.
