Resumo
O objetivo deste trabalho foi observar se o curativo de demora tem alguma influência no processo de reparo após o emprego de um plug de raspas de dentina em casos de necropulpectomia. Dentes de cães foram submetidos à pulpectomia e os canais deixados expostos ao meio oral até que lesões periapicais fossem detectadas radiograficamente. Os canais radiculares foram a seguir preparados e obturados com cones de guta-percha e cimento de óxido de zinco e eugenol, após a confecção de um plug apical de raspas de dentina, em sessão única, ou depois da aplicação de dois curativos de demora com para-inonoclorofenol-canforado. Seis meses após o tratamento, a análise histológica mostrou melhores resultados no grupo onde se empregou o curativo de demora.

Abstract
The object of this paper was to observe whether a dressing has some influence in the periapical healing process after apical plugging of pulpless teeth with dentin chips. The dental pulp of dog's teeth were removed and the root canals left exposed to the oral environment, until a periapical radiolucency was observed. The root canals were then instrumented and filled with zinc oxide eugenol cement and gutta-percha points, after an apical plugging of dentin chips, either in a single session or after two dressings with camphorated chlorophenol. Six months after the treatment, the histological data showed better results in the experimental group where camphorated chlorophenol dressing was employed.
