OBJECTIVE
This study evaluated the use of bioactive glass, PerioGlas, after retrograde filling with Super EBA cement in the treatment of periapical bone destruction.
STUDY DESIGN
Healing outcomes were followed up after endodontic surgery in 186 teeth. Outcomes were divided into two groups according to follow-up time: short- and long-term. The EBA group (n = 110) underwent endodontic surgery and retrograde filling with EBA cement. In the EBA + PerioGlas group (n = 76), PerioGlas was embedded in the bone cavity after retrograde filling.
RESULTS
The success rate in the EBA + PerioGlas group was 72% compared with 56% in the Super EBA group at the short-term follow-up and 74% and 84%, respectively, at the long-term follow-up. Healing of periapical bone destruction classified as uncertain at the short-term follow-up was considered successful in two out of three cases at the long-term follow-up.
CONCLUSION
This study found that PerioGlas as bone substitute did not significantly improve endodontic healing outcome.
目的
本研究评估了在使用超EBA水门汀进行根管倒充填后，生物活性玻璃（PerioGlas）在根尖周骨破坏治疗中的应用。
研究设计
对186颗牙齿进行牙髓手术后的愈合结果进行随访。根据随访时间将结果分为两组：短期和长期。EBA组（n = 110）接受牙髓手术并用EBA水门汀进行根管倒充填。在EBA + PerioGlas组（n = 76）中，根管倒充填后将PerioGlas植入骨腔。
结果
在短期随访中，EBA + PerioGlas组的成功率为72%，而超EBA组为56%；在长期随访中，两组的成功率分别为74%和84%。在短期随访中分类为不确定的根尖周骨破坏愈合情况，在长期随访中三分之二的病例被认为是成功的。
结论
本研究发现，PerioGlas作为骨替代物并不能显著改善牙髓治疗的愈合结果。
