摘要

背景:牙本质-牙髓复合体的仿生再生是一种涉及生物活性物质应用的现代方法。据报道,生物活性物质(如水泥或干细胞)能够控制牙髓细胞的信号传导和分化,从而限制炎症反应,使组织修复和再生。其中一种材料是MTA修复HP (MTA HP)——一种由矿物氧化物亲水颗粒组成的具有高可塑性的矿物三氧化物骨料(MTA)材料。目的:利用锥形束计算机断层扫描(CBCT)和微型计算机断层扫描(micro-CT)两种放射技术,分析人牙髓-牙本质复合体对MTA HP的反应。材料与方法:对6例30 ~ 37岁患者6颗无龋、完整的上颌、下颌第三磨牙或前磨牙进行分析。这些牙齿因正畸或手术原因被安排拔除。结果:三牙本质的检查参数在CBCT和micro-CT图像上比较,差异均无统计学意义(p < 0.05)。结论:与micro-CT类似,CBCT技术在鉴别和评估三级牙本质方面是有效的。此外,CBCT在临床环境中具有可用性的优势。利用放射学技术鉴定修复性牙本质参数的知识仍然不足,建议进一步研究。

Analysis of selected parameters of reparative dentin after direct pulp capping with MTA Repair HP in human teeth, using CBCT and micro-CT.

Background: The biomimetic regeneration of the pulp-dentin complex is a modern approach involving the application of a bioactive substance. Bioactive substances (e.g., cement or stem cells) have been reported to be able to control the signaling and differentiation of the pulp cells, thus limiting the inflammatory reactions and enabling the repair and regeneration of tissues. One of such materials is MTA Repair HP (MTA HP) - a type of mineral trioxide aggregate (MTA) material characterized by high plasticity, composed of hydrophilic particles of mineral oxides.

Objectives: The aim of the present study was to analyze the reaction of the pulp-dentin complex of human teeth to MTA HP using 2 radiological techniques - cone-beam computed tomography (CBCT) and micro-computed tomography (micro-CT).

Material and methods: In the study, 6 caries-free, intact maxillary and mandibular third molars or premolars from 6 patients aged 30-37 years were analyzed. The teeth were scheduled to be extracted for orthodontic or surgical reasons.

Results: No statistically significant differences in the examined parameters of the tertiary dentin were observed in the CBCT and micro-CT images (p < 0.05).

Conclusions: The CBCT technique, similarly to micro-CT, proved to be effective in identifying and assessing the tertiary dentin. Furthermore, CBCT has the advantage of usability in clinical settings. Knowledge on the parameters of reparative dentin identified with radiological techniques is still insufficient, and further research is recommended.
