Resumen

Objetivo: Comparar la efectividad de las terapias de sensibilización dental que usan láser diodo 940 nm y nitrato de potasio en pacientes con síntomas de hipersensibilidad dental (HD). Métodos: Este ensayo clínico aleatorizado incluyó 30 pacientes quienes habían recibido previamente terapia periodontal básica y presentaban recesiones gingivales clases I y II (Miller 1985) con síntomas de HD. La muestra fue asignada aleatoriamente a los dos grupos. Al primero (n=15) le fue aplicado láser 940 nm por 90 segundos en la superficie de la recesión, y se les suministró un tubo de glicerina para ser aplicado diariamente y evitar la generación de sesgos. El segundo grupo (n=15) recibió láser inactive como placebo y se le suministró un gel desensibilizante que contenía nitrato de potasio 0,5 g para aplicar dos veces al día durante 14 días. Se realizaron controles a los 15 minutos, 8 días, 15 días y 4 semanas. Los datos obtenidos se registraron en una table en Excel. Se emplearon U de Mann Whitney U y t Student para comparar los grupos (p=0,05). Resultados: Todos los pacientes del estudio mostraron reducción  de la HD, diferencias que fueron estadísticamente significativas (p<0,01) entre los dos grupos intervenidos. Conclusiones: Ambos, el láser diodo y el nitrato fueron efectivos en el manejo posterior a la terapia periodontal para el manejo de la HD. Sin embargo, las diferencias fueron mayores para el grupo de terapia con láser.
