ABSTRACT
Dental caries is an infectious, multifactorial, localized, transmissible process that leads to the destruction of hard dental tissue. Streptococcus mutans is considered to be the main microorganism associated with its development. The aim of this study was to determine presence and count of S. mutans in saliva samples from children with dental caries before and after an educational process including interviews, lessons, lectures, educational workshops and recreational activities on the importance of oral care and hygiene. Twentythree 3 to 6 year old schoolchildren provided 3 unstimulated saliva samples one before the educational process, one at 3 months and one at 6 months into the educational process. The samples were serially diluted and plated on Mitis Salivarius agar supplemented with bacitracin and 20% sucrose, and incubated anaerobically for 2 days at 37oC. Presumptive S. mutans isolates were identified with biochemical tests. Before the beginning of the educational process, and at 3 and 6 months into the educational process, S. mutans was found, respectively, in 22 (95.6%), 15 (65.2%) and 10 (43.5%) of the 23 children. The S. mutans count was reduced by 64.8% and 86.6% at 3 and 6 months, respectively, compared to the levels found before the educational process. These results indicate that educational intervention produced a significant reduction in S. mutans levels in the saliva of children with dental caries at 3 and 6 months into the educational process (AU)
RESUMEN
La caries dental es un proceso infeccioso multifactorial, localizado y transmisible que se caracteriza por la destrucción del tejido dental duro. Streptococcus mutans es considerado el principal microorganismo asociado al desarrollo de esta enfermedad. El objetivo de este estudio fue determinar la presencia y recuento de S. mutans en saliva de niños con caries dental antes y después de un proceso educativo. Con este fin se tomó saliva no estimulada de 23 niños con caries dental pertenecientes a un centro educativo con edades de 3 a 6 años. En todos los niños se tomaron 3 muestras de saliva antes del proceso educativo y a los 3 y 6 meses de iniciado el proceso educativo. El proceso educativo consistió en entrevistas, enseñanzas, conferencias, talleres educativos y actividades lúdicas sobre la importancia del cuidado e higiene oral. Después de su recolección, las muestras de saliva fueron serialmente diluidas y sembradas en Agar Mitis Salivarius con bacitracina y sacarosa al 20%. Los medios de cultivo sembrados se incubaron en anaerobiosis durante 2 días a 37ºC y los aislamientos presuntivos de S. mutans se identificaron con pruebas bioquímicas. Antes del inicio del proceso educativo, a los 3 y 6 meses de iniciado el proceso educativo se encontró S. mutans, respectivamente, en 22 de los 23 niños (95.6%), en 15 de los 23 niños (65.2%) y en 10 de los 23 niños (43.5%). En cuanto al recuento de S. mutans, se encontró una reducción de 64.8 % y 86.6% a los 3 y 6 meses, respectivamente, en comparación a los niveles encontrados antes del inicio del proceso educativo. En conclusión, los resultados indican que la intervención educativa realizada produjo una reducción significativa en los niveles de S. mutans en saliva de niños con caries dental después de 3 y 6 meses de iniciado el proceso educativo (AU)
