BACKGROUND
The study aims to investigate the pulp and periapical reaction and healing after capping with EndoSequence Root Repair Material (ERRM) combined with low-level laser application.
METHODS
In 6 rabbits, pulps were exposed via class V, half of the samples received a low-level diode laser at 980 nm. Thereafter, cavities were capped with regular-set ERRM. The specimens were processed for histomorphological examination after 2 weeks and two months.
RESULTS
After 2 weeks, images show mild inflammation and organized odontoblasts in lased group. The non-lased group shows more severe inflammation. The predentin thickness was thicker in the lased group with statistical significance (p < 0.05). After 2 months, inflammatory cells were sparse in both lased and non-lased groups. In the periapical area, group one showed dilated blood vessels and thick fibrous connective tissues. In group two, there were more numerous maturations of PDL fibers with scattered inflammatory cells and congested blood vessel.
CONCLUSIONS
Using low-level laser therapy in combination with ERRM for pulp capping shortens the inflammatory phase and enhances healing.
背景
本研究旨在探讨使用 EndoSequence Root Repair Material（ERRM）联合低水平激光应用对盖髓后的牙髓和根尖周反应及愈合情况的影响。
方法
在 6 只兔子中，通过 V 类洞暴露牙髓，其中一半样本接受 980nm 低水平二极管激光照射。然后，用常规凝固 ERRM 覆盖腔体。在 2 周和 2 个月后，对标本进行组织形态学检查。
结果
在 2 周时，激光组图像显示轻度炎症和有组织的成牙本质细胞，而非激光组显示更严重的炎症。激光组的前期牙本质厚度更厚，具有统计学意义（p<0.05）。在 2 个月时，两组的炎症细胞均稀疏。在根尖区，第 1 组显示扩张的血管和厚的纤维结缔组织。第 2 组中，PDL 纤维的成熟更多，有散在的炎症细胞和充血的血管。
结论
使用低水平激光治疗联合 ERRM 对牙髓进行盖髓可以缩短炎症期，促进愈合。
