Abstract
La terapia ortodóntica produce una mayor acumulación de placa bacteriana en los pacientes, observándose cambios ecológicos orales que causan aumento del número de estreptococos mutans, por lo que es importante una adecuada higiene bucal que ayude a disminuir las bacterias y prevenir la caries. Objetivo. El propósito fue comparar el efecto del uso de una pasta dental con xilitol, en el recuento de Streptcococcos mutans en pacientes con aparatología ortodóntica fija. Material y métodos. Se realizó un estudio cuasiexperimental de cegamiento simple. La muestra estuvo constituida por 34 pacientes adolescentes con aparatología ortodontica fija de ambo sexos que cumplieron los criterios establecidos, todos fueron instruidos en una técnica de cepillado y designados al azar a uno de los dos grupos: grupo experimental 17 pacientes que usaron una pasta dental con xilitol y 17 pacientes en el grupo control que utilizaron una pasta dental convencional con flúor. A ambos grupos se les tomó y procesó microbiológicamente placa bacteriana al inicio del estudio y a las 3 y 5 semanas para evaluar el recuento de streptococos mutans. Resultados. La prueba T-Student demostró que hubo menos unidades formadoras de colonias en los pacientes que utilizaron pasta dental con xilitol siendo significativa la diferencia en la quinta semana de uso (˂ 0.0001). Conclusiones. Existe mayor efectividad de la pasta dental con xilitol, en relación a la pasta dental solo con flúor en el recuento de Streptococos mutans, sin embargo, los pacientes de ambos grupos tuvieron menos unidades formadoras de colonias.
Orthodontic therapy produces a greater accumulation of bacterial plaque in patients, with oral ecological changes that cause an increase in the number of mutans streptococci, so it is important to have an adequate oral hygiene that helps to reduce bacteria and prevent caries. Objective. The purpose was to compare the effect of the use of a toothpaste with xylitol on the Streptococcus mutans count in patients with fixed orthodontic appliances. Material and methods. A single-blinded quasi-experimental study was carried out. The sample consisted of 34 adolescent patients with fixed orthodontic appliances of both sexes who met the established criteria. All were instructed in a brushing technique and randomly assigned to one of two groups: 17 patients in the experimental group used a toothpaste with xylitol and 17 patients in the control group used a conventional toothpaste with fluoride. Both groups had bacterial plaque taken and processed microbiologically at the beginning of the study and at 3 and 5 weeks to evaluate the streptococcus mutans count. Results. The T-Student test showed that there were fewer colony-forming units in patients who used xylitol toothpaste with the difference being significant at the fifth week of use (˂ 0.0001). Conclusions. There is greater effectiveness of toothpaste with xylitol in relation to toothpaste with fluoride alone in the Streptococcus mutans count; however, patients in both groups had fewer colony-forming units.
