本研究评价了一种技术，包括修复磨牙根管穿孔和引导组织再生，以恢复牙周组织，从分叉区域访问的网站。六只狗对下颌第四前磨牙和第一磨牙进行了根管治疗。每颗牙齿的远端牙根在分叉和根尖之间的分叉面上穿孔。进行了替换皮瓣手术，以准备并使用中间修复材料填充穿孔部位。将异种骨移植物置于入路截骨部位，并用GoreTex增强材料（GTAM）覆盖。对照包括未填充的穿孔和未使用骨移植物和/或GTAM。在术后6、12和24周处死犬。并发症更常见时，根穿孔留下未填补。组织形态计量学显示，在统计学上显着减少炎症和更多的骨填充根穿孔时，填补和GTAM，分别。
This study evaluated a technique that included retrofill to repair molar root canal perforations and guided tissue regeneration to restore the periodontium that was removed from the furcation area for access to the sites. Six dogs had root canal therapy on mandibular fourth premolars and first molars. The distal root of each tooth was perforated on the furcation aspect halfway between the furcation and the apex. Replaced flap surgery was performed for access to prepare and fill the perforation site with Intermediate Restorative Material. A bone xenograft was placed in the access ostectomy site and covered with GoreTex Augmentation Material (GTAM). Controls included unfilled perforations and not using bone grafts and/or GTAM. Dogs were killed at 6, 12, and 24 wk postsurgery. Complications were more common when root perforations were left unfilled. Histomorphometry revealed a statistically significant decrease in inflammation and more bone fill when root perforations were filled and GTAM was used, respectively.
