Some endodontists use iodoform in Sealapex in order to rend it more radiopac. This procedure is empiric and for this reason we decided to observe, histologically, if the iodoform introduces some modification in the biological properties of Sealapex. Thirty root canals of dogs' teeth were overinstrumented and filled, by lateral condensation technique, with gutta percha points and Sealapex, with or without iodoform. The iodoform was added in two different proportions: 30 mg or 112 mg for one centimeter of the base and one centimeter of the catalyst of Sealapex. The pieces were removed for histological studies, 6 months after the treatment. The histological results showed that Sealapex encourages apical closure by cementum deposition and that the addition of iodoform does not change that biological property.
一些牙髓病医生在Sealapex中使用碘仿，以便使其在X射线下更显阻射。此操作是经验性的，因此我们决定从组织学角度观察碘仿是否会对Sealapex的生物学特性产生一些改变。通过侧方加压技术，用牙胶尖和Sealapex对30颗犬齿的根管进行过度预备并充填，其中一部分添加了碘仿，一部分未添加。碘仿以两种不同比例添加：每1厘米Sealapex的基质和1厘米催化剂添加30毫克或112毫克碘仿。治疗6个月后取出样本进行组织学研究。组织学结果表明，Sealapex通过牙骨质沉积促进根尖闭合，并且添加碘仿不会改变该生物学特性。
