ABSTRACT

SUMMARY:

The aim of the article was to study changes in periodontal tissues in rats with spontaneous periodontitis (SP) and to evaluate the effect of hyaluronic acid (HA) on the state of the periodontium. Wistar rats with signs of SP were divided into 6 groups 1) intact group; 2) intact animals with HA "HD-1,0 MDa"; 3) SP group; 4) SP with HA "S-2,4 MDa"; 5) SP with HA "ST-2,4 MDa"; 6) SP with HA "HD-1,0 MDa". The study of the periodontium rats with SP noted the main structural changes (collagen reduction, resorption of alveolar bone, dilatation and stasis of the vessels of the periodontium, gingival papilla and tooth pulp), which were assessed as moderate. Morphological evidence of inflammation was infiltration of neutrophils into the connective tissue of the gums, without the formation of abscesses. Local administration of HA did not cause additional structural damage in periodontal tissues of rats with SP, but also did not affect changes in the microvascular system of periodontium and tooth pulp, periodontal ligaments, only a tendency to inhibit alveolar bone resorption in rats was noted. One can consider the tendency to improve the condition of periodontal tissues in the group of rats injected with high molecular HA and HA with mannitol (2.4 MDa).
RESUMEN
RESUMEN El objetivo del artículo fue estudiar los cambios en los tejidos periodontales en ratas con periodontitis espontánea (PE) y evaluar el efecto del ácido hialurónico (HA) sobre el estado del periodonto. Las ratas Wistar con signos de PE se dividieron en 6 grupos 1) grupo intacto; 2) animales intactos con HA "HD-1,0 MDa"; 3) grupo PE; 4) PE con HA "S-2,4 MDa"; 5) PE con HA "ST-2,4 MDa"; 6) PE con HA "HD-1,0 MDa". En las ratas con PS se observaron los principales cambios estructurales (reducción de colágeno, reabsorción del hueso alveolar, dilatación y estasis de los vasos del periodonto, papila gingival y pulpa dentaria), que fueron evaluados como moderados. La evidencia morfológica de inflamación fue la infiltración de neutrófilos en el tejido conectivo de las encías, sin la formación de abscesos. La administración local de HA no causó daño estructural adicional en los tejidos periodontales de las ratas con PE, pero tampoco se produjo cambios en el sistema microvascular del periodonto y en la pulpa dental y ligamentos periodontales.Se observó una tendencia a inhibir la resorción del hueso alveolar. Se puede considerar la tendencia a mejorar el estado de los tejidos periodontales en el grupo de ratas inyectadas con HA de alto peso molecular y HA con manitol (2,4 MDa).
