Abstract

This study evaluated the impact of long-term storage conditions (medium and time) on the development of experimental dentinal microcracks through micro-computed tomography. Sixty freshly extracted premolars were stored in formalin, water, or dry conditions (n = 20) and scanned after 72 h, 30 days, 6 months and 3 years of extraction. The effect of the storage medium and time on the occurrence of dentinal defects was statistically evaluated. A total of 211 000 images were screened revealing the existence of 11 519 slices with dentinal defects. Dry conditions significantly contributed to the development of new defects in all time points. During the 3-year follow-up period, no new defects were detected in the teeth that were stored in water and, in a single tooth, in the formalin group, after 6 months of storage.

长期储存条件对实验性牙本质微裂纹发育的影响。

本研究通过微型计算机断层扫描评估了长期储存条件（介质和时间）对实验性牙本质微裂纹发展的影响。将60颗新鲜提取的前磨牙储存在福尔马林、水或干燥条件下（n = 20） 72后扫描 h、 30 天，6 月和3 多年的开采。对储存介质和时间对牙本质缺陷发生的影响进行统计学评估。共211 000张图像被筛选出来，揭示了11 519片牙本质缺损。干燥条件在所有时间点都显著促进了新缺陷的发展。在3年的随访期内，储存在水中的牙齿没有发现新的缺陷，福尔马林组在6 储存数月。

期刊介绍： The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
