The purpose of this study was to evaluate the radiographic density of the alveolar bone of the maxilla after extraction of the impacted canines and using the pulp tissue as an autogenous graft.
This prospective cohort study recruited 14 patients (8 females and 6 males) between 2021 and 2023, with an average age of 35 years. All participants had palatally impacted maxillary canines. The impacted teeth were extracted surgically. The extracted teeth were then used for autogenous grafting. The pulp tissue was removed, cut into small pieces, and placed on an absorbable gelatin sponge before being inserted into the extraction socket. The wound was subsequently closed meticulously. After 4 months, the bone density was assessed radiographically using the Hounsfield Scale on cone beam computed tomography scans.
After 4 months, the mean radiographic bone density value in the extraction area was (652.77 ± 56.13 HU), while the average density of the original bone was (659.7 ± 39.6 HU).
Within the limits of this study, dental pulp tissue can be used to restore bony defects of the alveolar bone in the maxilla. However, further research is needed to confirm these findings.
本研究的目的是评估拔除阻生尖牙并使用牙髓组织作为自体移植物后上颌牙槽骨的影像学密度。
这项前瞻性队列研究在2021年至2023年期间招募了14名患者(8名女性和6名男性),平均年龄为35岁。所有参与者均有腭侧阻生的上颌尖牙。通过手术拔除阻生牙。然后将拔除的牙齿用于自体移植。去除牙髓组织,切成小块,置于可吸收明胶海绵上,再插入拔牙窝。随后仔细缝合伤口。4个月后,在锥形束计算机断层扫描上使用亨氏单位(Hounsfield Scale)对骨密度进行影像学评估。
4个月后,拔牙区域的平均影像学骨密度值为(652.77±56.13亨氏单位),而原骨的平均密度为(659.7±39.6亨氏单位)。
在本研究的范围内,牙髓组织可用于修复上颌牙槽骨的骨缺损。然而,需要进一步的研究来证实这些发现。
