摘要

目的：本体外研究的目的是探讨树脂浸润下胶粘剂封闭牙釉质裂纹的遮蔽效果，并与使用通用胶粘剂进行比较。方法：采用摆锤冲击试验机对牛牙唇面进行牙釉质开裂试验。用ICON （DMG）或Scotchbond Universal Plus （3M）树脂浸渍对标本进行粘接处理。术前和术后采用三种方法拍摄标准化数字图像：前手电、后透射光和诊断相机（KaVo）。四名经过校准的评分者对每种类型的所有图像进行定性视觉评估：严重可见的牙釉质裂纹(1)，清晰可见的牙釉质裂纹(2)，轻微可见/美观可接受的牙釉质裂纹(3)和不可见的牙釉质裂纹(4)。选择标本通过共聚焦显微镜测量浸润深度。结果：术后使用ICON对牙釉质裂纹的遮蔽效果明显高于使用Scotchbond Universal Plus组（p < 0.001）。ICON的浸润深度显著高于Scotchbond Universal Plus （p < 0.002）。结论：树脂浸润治疗创伤性牙釉质裂缝是一种简单有效的治疗方法，其疗效优于粘接剂。需要进一步的研究来评估通过树脂渗透实现的光学改善的长期稳定性。临床意义：树脂浸润可以为临床医生提供一种治疗选择，以改善创伤性牙釉质裂纹的美观性。

Resin infiltration of trauma-induced enamel cracks – a proof-of-concept

Objectives

The aim of this in-vitro study was to investigate the masking efficacy of adhesively sealed enamel cracks with resin infiltration compared with the use of a universal adhesive.

Methods

Enamel cracks were induced on the labial surfaces of bovine teeth using a pendulum impact tester. Specimens were treated adhesively by resin infiltration with ICON (DMG) or Scotchbond Universal Plus (3M). Standardized digital images were taken pre- and postoperatively by three methods: flashlight from the front, transmitted light from behind, and DiagnoCam (KaVo). Four calibrated raters performed the qualitative visual evaluation of all images of each type: severely visible enamel cracks (1), clearly visible enamel cracks (2), slightly visible/aesthetically acceptable enamel cracks (3) and no visible enamel cracks (4). Specimens were selected to measure infiltration depth by confocal microscopy.

Results

Postoperatively, the masking efficacy in teeth with enamel cracks was significantly higher using ICON compared with Scotchbond Universal Plus in all groups (p < 0.001). Infiltration depths of ICON were significantly higher compared to those of Scotchbond Universal Plus (p < 0.002).

Conclusions

Resin infiltration offers a straightforward and effective treatment option for masking trauma-induced enamel cracks, demonstrating superior efficacy over adhesive sealing. Further studies are necessary to evaluate the long-term stability of the optical improvements achieved through resin infiltration.

Clinical Significance

Resin infiltration might pose a therapeutic option for clinicians to enhance the aesthetic appearance of trauma-induced enamel cracks.

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
