ABSTRACT
Nicotine is an alkaloid toxic effects of oral cavity. In this study,14 adult Sprague-Dawley rats weighing 230-260 mg (+/-10 mg) were used as experimental animal. The rats of experimental group (n=6) were nicotinized systemically with nicotine sulphate, 2mg/kg subcutaneously, daily in period of 28 days. Pulp, alveolar bone tissue, periodontal membrane and gingival epithelial junction were investigated in these regions in incisive teeth longitudinal cross-section. Thinning of the collagen fibers in the pulp tissue, vascular congestion, and inflammatory cell infiltration were observed. Mesenchymal tissues that is stained positive for vimentin lay underneath the epithelium. A strong expression of vimentin can be observed in formed periodontal ligament.
RESUMEN
La nicotina es un alcaloide con efectos tóxicos sobre la cavidad oral. En este estudio, se utilizaron como animales de experimentación, 14 ratas Sprague-Dawley adultas con un peso entre 230-260 mg (+/- 10 mg). Las ratas del grupo experimental (n = 6) fueron expuestas a nicotina sistémicamente con sulfato de nicotina, 2mg/kg vía subcutánea al día, durante 28 días. Fueron estudiadas la pulpa, tejido óseo alveolar, membrana periodontal y la unión del epitelio gingival en los dientes incisivos en secciones transversales y longitudinales. Se observó un adelgazamiento de las fibras de colágeno, congestión vascular e infiltración de células inflamatorias en el tejido de la pulpa. Los tejidos mesenquimales que tiñeron positivamente para vimentina se ubicaron debajo del epitelio. Una fuerte expresión de vimentina se pudo observar en el ligamento periodontal.
