description Physiological events involving tooth replacement processes generate histochemical modifications that induce root resorption process. CD44 is a glycoprotein transmembrane involved in cell adhesion to extracellular matrix components; it participates in motility, migration and immobilizes the hyaluronic acid on the cell surface. This study included pulpar and mineralized tissues from teeth in different involutive stages, evaluating CD44 concentration. It was analyzed a total of 28 pulpar samples from health deciduous teeth (n=10), dental caries deciduous (n=12), deciduous supernumerary (n=3) and permanent supernumerary (n=3). It was found that the concentration of CD44 in deciduous teeth progressed towards increasing resorption activity. CD44 concentration was statistically similar in healthy and caries deciduous samples. In permanent supernumerary teeth, the concentration of CD44 was significantly greater than in deciduous teeth, with or without cavities, and still significantly higher than reported in deciduous supernumerary teeth. It was concluded that findings suggest that the hyaluronate receptor molecule is present most significantly in dental pulp where there is no process of resorption.

Los eventos fisiológicos que se involucran en los procesos del recambio dentario generan modificaciones histoquímicas que inducen el proceso de reabsorción radicular. La molécula CD44 es una glicoproteina transmembrana implicada en la adhesión entre células y componentes de la matriz extracelular; participa en la motilidad, migración e inmoviliza al ácido hialurónico en la superficie celular.Se trabajó con tejidos pulpares y mineralizados provenientes de piezas dentarias de la primera dentición en diferentes estadios involutivos, donde se evaluaron los distintos niveles de concentración del CD44. Se analizaron un total de 28 muestras provenientes de pulpas sanas (n=10), pulpa con caries (n=12), supernumerarios deciduos  (n=3) y supernumerarios permanentes  (n=3).Se comprobó que la concentración de CD44 en dientes deciduos se incrementó en consonancia con el aumento de la actividad resortiva en los procesos de rizólisis.  La concentración de CD44 fue estadísticamente similar en las muestras de pulpa decidua sana y con caries, mientras que en pulpa sana de dientes supernumerarios permanentes fue significativamente mayor que la registrada en la pulpa de deciduos, con o sin caries, y aún significativamente superior a la reportada en la pulpa de dientes supernumerarios deciduos. Se concluyó que los hallazgos sugieren que la molécula del receptor de Hialuronato está presente de manera más considerable en pulpas dentarias donde no hay procesos de reabsorción. Histochemical Variation in rhizolysis processes of first dentition teeth.
