Abstract

Sixty root canals of 3 adult dogs were instrumented one millimeter beyond the apex and overfilled with Calcium hydroxide-iodoform/distilled water-Mixture, Grossman's Sealer and Maisto antiseptic Paste. Periapical tissues were examined histologically after eighteen months. The best results were observed in the specimens treated with Calcium hydroxide-iodoform and Maisto antiseptic Paste. With those filling materials some cases exhibited closure of the apical foramen by cementum deposition and the periapical inflammatory reaction was not so frequently observed as it was with Grossman cement.

Keywords

Overfilling, Grossman's Sealer, Maisto antiseptic Paste, Calcium hydroxide-iodoform

Resumo

Sessenta canais radiculares de 3 cães adultos jovens foram instrumentados um milimetro além do ápice e sobreobturados com pasta de hidróxido de cálcio-iodofórmio e água destilada, cimento de Grossman e pasta antisséptica de Maisto. A análise histológica dos resultados foi efetuada após um perfodo de dezoito meses. Os melhores resultados foram observados nos espécimes tratados com a pasta de hidróxido de cálcio iodofórmio e água destilada e com a pasta antisséptica de Maisto. Com estes materiais obturadores, alguns casos exibiram selamento do forame apical por deposição de cemento e a reação inflamatória periapical não foi constatada com a mesma frequência observada com o cimento de Grossman.

Palavras-chave

Sobreobturação, cimento de Grossman, pasta antisséptica de Maisto, hidróxido de cálcio iodofórmio
