Abstract
En el movimiento dentario se encuentra involucrado además del propio diente el tejido de soporte periodontal; en el fluido crevicular aparecen determinados factores bioquímicos relacionados con la reabsorción y la formación ósea durante el movimiento ortodóncico.El objetivo de este estudio fue conocer los niveles de interleuquina IL 1β en el fluido crevicular para conocer el proceso inflamatorio que se produce durante el movimiento ortodóncico y saber si puede estar asociado o no al dolor que perciben los pacientes durante el tratamiento.Fueron seleccionados 29 pacientes adultos (15 mujeres, con una edad media de 21,8 ± 1,2 años y 14 hombres, con una edad media de 21,2 ± 1,5 años) que iban a ser tratados ortodóncicamente mediante aparatología fija multibrackets. Se cementaron brackets (0.022 x 0.028 pulgadas, Mini Master, American Orthodontics, Sheboygan, WI, USA, técnica MBT) en la cara vestibular de los dientes experimentales, y un tubo de cementado directo en cada primer molar superior del mismo lado del diente experimental. Se aplicó una fuerza continua de 100 g por medio de un coil spring de nikel-titanio GAC Sentalloy 100gr Closed Coil Springs (GAC International Inc, Bohemia, NY, USA), y se tomaron muestras de fluido crevicular en mesial (tensión) y distal (compresión) del diente experimental, y en distal del diente control, durante varias visitas: justo antes de aplicar la fuerza, a las 24 horas posteriores, a los 7 y a los 28 días después...
Periodontal tissue is actively involved in dental movement besides the tooth itself; certain biochemical factors related to bone resorption and formation during orthodontic movement appear in the gingival crevicular fluid.The aim of this study was to appraise the levels of interleukin IL-1β in the crevicular fluid in order to know the inflammatory process that occurs during orthodontic movement and to learn whether or not it may be associated with the pain perceived by patients during treatment.Twenty-nine adult patients (15 women, with an average age of 21.8 ± 1.2 years and 14 men, with an average age of 21.2 ± 1.5 years) were selected to be treated orthodontically by fixed-devices multibrackets. Brackets (0.022 x 0.028 inches, Mini Master, American Orthodontics, Sheboygan, WI, USA, MBT technique) were cemented into the vestibular side of the experimental teeth. A direct cementing tube was cemented into the upper first molar on the same side of the experimental tooth. A 100 g continuous force was applied by means of a Nikon-Titanium coil spring GAC Sentalloy 100 g Closed Coil Springs (GAC International Inc, Bohemia, NY, USA). Crevicular fluid samples were collected in mesial (tension) and distal (compression) of the experimental tooth and distal of the control tooth prior to the application of the orthodontic force, 24 hours later, and 7 and 28 days after applying such force...
