RESUMEN
El objetivo de este estudio fue evaluar el efecto clínico y microbiológico de microgránulos de Minociclina, colocados subgingivalmente como coadyuvante del raspaje y alisado radicular en pacientes con Periodontitis crónica severa. Participaron 26 sujetos voluntarios con Periodontitis crónica, no fumadores. Se seleccionaron 4 sitios contralaterales con Sangrado al Sondaje (SS) y Profundidad al Sondaje (PS) > 6 mm. Condición Basal (CB): se registró, PS y Nivel de Inserción (NI). Se determinó mdiante PCR la presencia de Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), Treponema denticola (Td) y Aggregatibacter actinomycetemcomitans (Aa). Un lado de la boca fue aleatoriamente asignado al tratamiento experimental: grupo T, el otro al tratamiento control: grupo C. Al día 30 y 90 se repitieron los exámenes clínicos y microbiológicos. Día 30: el SS se redujo al 81 por ciento en el grupo C y al 12 por ciento en el grupo T (p<0,05). Estas diferencias se mantuvieron al día 90 (C: 58 por ciento, T: 8 por ciento) (p<0.05). Día 30 y 90: hubo disminución de la PS en ambos grupos, siendo significativamente mayor en el grupo T (p<0,05). En ambos grupos hubo disminución significativa del NI (p<0,05), no hubo diferencias entre los grupos al día 30 y sí al día 90. A los 30 y 90 días en ambos grupos se redujo la prevalencia para Pg, Tf ,Td y Aa. A los 30 y 90 días la reducción de sitios con Pg fue mayor en el grupo T (p=0,002). A los 90 días Td disminuyó en el grupo T y aumentó en el grupo C (p=0,023). No se observaron efectos adversos. Los resultados mostraron que la aplicación subgingival de microgránulos de minociclina adjunta al raspaje y alisado radicular produjo una reducción mayor del SS, la PS y el NI que el raspaje y alisado solo, aumentó la probabilidad de suprimir Pg y retardó la recolonización con Td.
ABSTRACT
The aim of this study was to evaluate clinical and microbiological effects of subgingival minocycline microgranules when used as an adjunct to scaling and root planing in subjects with Chronic periodontitis. Twenty-six non-smoker volunteers participated in the study. Four opposite sites, clinically standardized, with bleeding on probing (BOP) and pocket depth (PD) ≥ 6 mm were selected. Baseline BOP, PD and Clinical attachment level (CAL) were measured and microbiological samples were collected from the study sites and analyzed using PCR. Porphyromonas gingivalis (Pg) Tannerella forsythia (Tf), Treponema denticola (Td) and Aggregatibacter actinomycetemcomitans (Aa) were detected. One side of the mouth was randomly allocated to the experimental treatment: scaling and root planing plus minocycline microgranules (Test group=T) and the other side of the mouth toscaling and root planing alone (Control group=C). At days 30 and 90, clinical and microbiological examination was repeated. After 30 days BOP was reduced to 81% in C and to 12% in T and at day 90 to 58% in C and to 8% in T (p<0.05). PD wassignificantly reduced in both groups (C: 4.8mm, T: 4.2mm) favoring T at days 30 and 90 (p<0.05). CAL reduction at day 30 showed no difference between groups. At day 90, CAL reduction was higher in T (p<0.05). At days 30 and 90 Pg, Tf, Td and Aa was reduced in both groups. Pg reduction wassignificantly greater in group T. At day 90 frequency of sites with Td decreased in T and increased in C (p<0.05). No adverse effect was observed. This study showed that minocycline microgranules adjunct to scaling and root planing resulted in grater reduction of BOP and PD, higher CAL gain, increased probability of Pg suppression and retarded recolonization of Td than root instrumentation alone.
