    Abstract
    Recientemente los aspectos biológicos de las reconstrucciones fijas han recibido atención porque los materiales usados en estas prácticas poseen gran capacidad de acumular y retener placa. Las bacterias de esta placa están dispuestas en una matriz denominada biopelícula. El objetivo de este estudio fue determinar las bacterias anaeróbicas presentes en el surco gingival de pacientes durante el tratamiento prostodóntico fijo. Se analizaron 45 muestras. Como grupo experimental, se estudiaron 30 muestras provenientes de pacientes con prótesis parcial fija y 15 muestras provenientes de personas sin este tratamiento prostodóntico, como grupo control.Las muestras obtenidas con punta de papel, fueron aisladas en agar sangre e incubadas en medio anaerobio. Se les realizó la prueba de aerotolerancia y la identificación se hizo con el sistema RapID TM ANA II System Remel. Se aislaron 12 bacterias anaerobias correspondientes a: 8,33% bacilos Gram negativos; 58,33 % bacilos Gram positivos y 33,33 % cocos Gram positivos. En el grupo control ninguna bacteria anaerobia fue aislada. únicamente fueron observados cocos facultativos Gram positivos. Aunque no se ha descrito que la presencia de placa en prótesis fijas tenga alguna clase de impacto negativo sobre los tejidos periodontales, la acumulación de ésta por un período extendido puede convertirse en un factor de riesgo para un problema de salud pública, como la enfermedad periodontal. Los resultados de este estudio confirmaron que la presencia de prótesis fijas resultó en un cambio en la composición de la microflora anaeróbica del surco gingival, compatible con enfermedad periodontal.
     
    Present anaerobic bacteria in gingival sulcus of patients with fixed partial dentures Recently, the biological aspects of fixed reconstructions have been given attention because dental materials have great capacity to accumulate and retain plaque. The microflora at both tooth and fixed partial prostheses can be identified as biofilms, which are composed of microcolonies of bacterial cells distributed in a shaped matrix. The purpose of this study was to isolate anaerobic bacteria in gingival sulcus from patients during fixed partial denture treatment. 45 samples were analyzed. 30 patients with fixed partial dentures treatment and 15 subjects without partial denture treatment were enrolled in the study. Microbiologic samples were obtained by inserting paper points into the gingival sulcus.Samples were cultured for anaerobic bacteria on blood agar. The plates were placed into an anaerobic chamber. Later, aerotolerance tests were performed for each different colony. RapID TM ANA II System Remel was used for identification of anaerobes. A total of 12 anaerobic bacteria were observed: 8.33 % gram–negative bacilli, 58.33 % gram-positive bacilli, 0 % Gram-negative cocci, and 33.33 % gram-positive cocci. In the control group none anaerobic bacteria was isolated. Only facultative gram-positive cocci were observed (100%). The results of this study have confirmed that the presence of fixed partial dentures resulted in a change in the composition of the anaerobic microflora of the gingival sulcus, compatible with periodontal disease.
