OBJECTIVE
The aim of this study was to evaluate the rat alveolar socket response to implanted polyethylene tubes filled with a light-cured MTA or Angelus MTA.
STUDY DESIGN
Fifty-seven Wistar rats received an implant filled with one of the materials in the dental socket of the right central incisor. After 30, 60, and 90 days, animals were killed, and the right hemimaxillas were removed and processed to be analyzed on light microscopy. After embedding in paraffin, 6-μm-thick sections were obtained and stained with hematoxylin and eosin. Qualitative and quantitative analyses of the reaction were performed.
RESULTS
It was observed that the light-cured MTA presented a similar response compared with Angelus MTA, characterized by the reduction of the chronic inflammatory response and organization of the alveolar bone close to the materials, especially at the 90th day of observation.
CONCLUSIONS
It was concluded that both materials were well accepted by the alveolar tissue of rats, with the formation of mineralized tissue close to the materials.
目的
本研究旨在评估大鼠牙槽窝对植入填充光固化MTA或安捷lus MTA的聚乙烯管的反应。
研究设计
57只Wistar大鼠在右上中切牙牙槽窝植入填充其中一种材料的植入物。在30天、60天和90天后，处死动物，取出右半侧上颌骨并进行处理，以便在光学显微镜下分析。石蜡包埋后，获得6μm厚的切片，并用苏木精和伊红染色。对反应进行定性和定量分析。
结果
观察到光固化MTA与安捷lus MTA表现出相似的反应，其特征是慢性炎症反应减轻，牙槽骨在材料附近形成组织，尤其是在观察的第90天。
结论
得出的结论是，两种材料均被大鼠牙槽组织良好接受，材料附近形成矿化组织。
