Fourteen root perforations were performed for microscopic evaluation of the repair of interradicular tissue in dogs' teeth. These perforations were accomplished at low-speed with a STP 58 bur at the cervical third of the mesial root toward the furcation under irrigation with saline solution, followed by immediate sealing with ProRoot MTA, MTA-Angelus and white Portland cement. The dogs were killed after 90 days, revealing good results. The Kruskal-Wallis test did not demonstrate any statistically significant difference. It was concluded that the three materials showed good sealing in mineralized tissue, with complete closure, and they were free of inflammation in most teeth.
在犬齿上进行了14次牙根穿孔，以对根间组织修复进行微观评估。这些穿孔是在生理盐水冲洗下，使用STP 58车针在近中根颈三分之一处朝向分叉处以低速完成的，随后立即用ProRoot MTA、MTA-Angelus和白色波特兰水泥封闭。90天后处死犬只，结果良好。Kruskal-Wallis检验未显示任何统计学上的显著差异。得出的结论是，这三种材料在矿化组织中显示出良好的封闭性，实现了完全封闭，并且大多数牙齿没有炎症。
