Resumen
Los procedimientos quirúrgicos preprotésicos, como el alargamiento clínico de la corona (ACC), pueden causar dolor, malestar e inflamación posoperatoria, lo que requiere la prescripción de medicamentos. Sin embargo, el uso prolongado e indiscriminado de estos medicamentos suele provocar efectos adversos en la salud general. El objetivo de este estudio es evaluar un sistema local de liberación controlada que utiliza gel de clorhexidina (CHX) posterior a cirugías preprotesicas periodontales para controlar el dolor posoperatorio, en comparación con un grupo de placebo. Se realizó un ensayo clínico aleatorizado, controlado, doble ciego, de grupos paralelos con múltiples dosis. Se seleccionó una muestra de 10 pacientes, con edades entre 18 y 60 años, que requerían un procedimiento de alargamiento de corona. Se formaron dos grupos: el grupo A recibió gel de clorhexidina (CHX) al 0,2% y el grupo B recibió un placebo. La puntuación media de la escala visual analógica (EVA) (en mm) fue de 3,32 para el grupo A y de 4,85 para el grupo B (p=0,05), y los resultados no mostraron diferencias estadísticamente significativas. Pocos estudios han evaluado el efecto y la influencia del gel CHX al 0,2% en el control del dolor posoperatorio. Algunos informes sugieren que el uso intraalveolar de gel CHX es más eficaz que la administración de 10 mg de ketorolaco solo. En este estudio, no hubo diferencias estadísticamente significativas, lo que indica que el uso de gel CHX al 0,2% aplicado después de la cirugía preprotésica puede no reducir significativamente el dolor posoperatorio.
