RESUMO
Evaluar la tasa de sobrevivencia y la capacidad preventiva de los sellantes de ion¢mero de vidrio de alta viscosidad colocados de acuerdo al protocolo propuesto por el tratamiento restaurador atraumatico (TRA), en primeros molares permanentes en ni¤os de 6 a 12 a¤os de edad, en una comunidad de alto riesgo. Material y mtodos. Se trataron 75 primeras molares permanentes de 34 ni¤os de la Instituci¢n Educativa Jos Olaya Balandra en el balneario de Bujama, distrito de Mala, Ca¤ete, Per£. Los sellantes se colocaron utilizando ion¢mero de vidrio de alta viscosidad siguiendo el protocolo del TRA y fueron evaluados luego de 12 meses utilizando los criterios de la Organizaci¢n Mundial de la Salud (OMS). Resultados. Las piezas evaluadas mostraron que 56,4% present¢ sellantes completos (c¢digo 0); el 23,6% sellantes parcialmente presentes sin caries (c¢digo 1); el 1,8% sellantes parcialmente presentes con signos de caries (c¢digo 2), y el 18,2% present¢ ausencia de sellantes sin presencia de caries (c¢digo 3). Empleando el criterio de efectividad biol¢gica se establece que 98,18% de las piezas inicialmente tratadas permanecieron libres de caries. Existi¢ una diferencia significativa (p<0,05) en relaci¢n a la ubicaci¢n de la pieza, observ ndose mayores tasas de retenci¢n en las primeras molares inferiores (67,9%) al compararlas con las superiores (44,4%). Conclusiones. Los sellantes TRA demostraron tener un gran potencial para prevenir lesiones de caries oclusales en primeras molares permanentes a los de 12 meses de seguimiento.
To evaluate the survival rate and preventive capacity of high viscosity glass ionomer sealants placed according to the protocol proposed by ART, in first permanent molars in children aged 6 to 12 years old, in a high risk Peruvian community. Material and methods. 75 first permanent molars were treated from 34 children of the school Jose Olaya Balandra in Bujama, district of Mala in Ca¤ete, Peru. Sealants were placed using high viscosity glass ionomer following the ART protocol and they were evaluated after 12 months using the World Health Organiation (WHO) criteria. Results. Evaluated pieces showed that 56, 4% had completed sealant (Code 0), 23, 6% partially sealants present without caries (code 1), 1,8% partially sealants present with signs of decay (Code 2) and 18,2% had no sealant without the presence of caries (code 3). Using the biological effectiveness criterion states that 98, 18% of the parts treated initially remained free of decay. There was a statistically significant difference (p<0,05) relative to the location of the piece, showing higher retention rates in the first molars (67, 9%) when compared to higher (44,4%). Conclusions. The ART sealants showed a great potential to prevent oclusal caries lesions in first permanent molars after 12 months of follow up.
