Inducing Apical Periodontitis in Mice

This study presents a novel protocol for locally inducing apical periodontitis in mice, facilitating controlled investigation of periapical inflammation. The method involves drilling the mouse's tooth to expose pulp and offers various analysis techniques, including micro-CT and histology.

Frequently Asked Questions

What is apical periodontitis?

Apical periodontitis is an inflammatory condition affecting the dental pulp and surrounding tissues, typically caused by infection.

Why use mice in this study?

Mice provide an accessible and controlled model for studying complex dental diseases.

What are the main advantages of this protocol?

It is cost-effective, technically simple, and allows for controlled observation of periapical inflammation.

What analysis methods are used?

Micro-CT imaging and histology are utilized to assess inflammation and tissue structure.

How is the protocol validated?

Validation is achieved through consistent observations of induced inflammation and tissue responses.

Can this method be applied to other studies?

Yes, it can be adapted for various dental and pulpal research projects.

What long-term effects are monitored post-procedure?

Animal weight and behavior are monitored for 42 days following the procedure.

在这里,我们提出一个协议,本地诱导小鼠的牙周炎。我们展示如何在老鼠的牙齿上钻一个洞,并暴露它的果肉,以引起局部炎症。研究这种炎症性质的分析方法,如微CT和成体学,也进行了演示。

我们的协议允许在可访问且受控的小鼠模型中研究周内炎。因此，此协议比患者样本或体外模型具有优势。该技术的主要优点是鼠标已经研究得很好，而且该方法在技术上在设施要求方面很简单，而且具有成本效益。

由于牙齿尺寸小，此过程具有挑战性，因此将程序可视化以了解该技术的定位和性能是有益的。在确认对头趾捏没有反应后，将鼠标放在紧闭细胞挤出聚苯乙烯泡沫表面的主导手侧，用胶带固定爪子。使用每对切口的单根橡皮筋，以及固定在闭合细胞挤压聚苯乙烯泡沫表面的长针，支撑嘴张开。
