Abstract
This investigation was conducted to observe if an oily or a water soluble vehicle could influence the healing process of periapical tissues after root canal treatment with calcium hydroxide. The research was developed in dog's teeth and the histological results were analysed 90 days after the treatment. HeaJing with closure of the periapical foramina by hard tissue deposition was observed when the oily vehicle (Lipidiol) was employed. A resorption of the filling material and an ingrowth of a chronic inflammatory connective tissue were the histological features when calcium hydroxide prepared with a water soluble vehicle (Telebrix) was used. The results obtained suggest that the oily vehicle improved the properties of calcium hydroxide, encouraging calcium salts deposition after root canal treatment.

Resumo
O objetivo do presente trabalho foi observar se um veículo oleoso ou aquoso pode influenciar o processo de reparo dos tecidos periapicais após o tratamento endodôntico com hidróxido de cálcio. A experimentação foi desenvolvida em dentes de cites e os resultados histológicos foram analisados 90 dias após o tratamento. Quando o veículo oleoso (Lipidiol) foi empregado, observou-se selamento biológico do forameapical pela deposição de tecido duro. Quando o hidróxido de cálcio foi preparado com um veículo aquoso (Telebrix), observou-se como característica histológica a reabsorção do material obturador e a invaginaçito de um tecido conjuntivo com infiltrado inflamatório crônico. Os resultados obtidos sugerem que o veículo oleoso (Lipidiol) melhorou as propriedades do hidróxido de cálcio, estimulando a deposiçito de sais de cálcio após o tratamento endodôntico.
