牙、颌骨、牙周组织的切片,通常称为软硬组织联合切片,是口腔病理学和口腔医学研究中最常用的技术之一。对这类标本的观察要求比较高,既要求看清软组织和硬组织的组织结构,又要求看清牙和骨之间的关系。制作较一般组织困难,不易作连续切片。传统的火棉胶包埋法,时间长,切片厚,结构不清晰,还必须备有专门的推拉式切片机。牙颌骨联合切片石蜡法的应用解决了组织结构清晰度的问题,用普通切片机即可切片。但制作步骤复杂,也不经济。
Tooth, jaw, periodontal tissue sections, commonly referred to as hard and soft tissue sections, are one of the most commonly used techniques in oral pathology and stomatology. The observation requirements of such specimens are relatively high, requiring both to see the soft tissue and hard tissue organizational structure, but also requires to see the relationship between teeth and bone. More difficult to make than the average organization, not easy to make a continuous slice. Traditional fire cotton embedding method, a long time, sliced thick, the structure is not clear, you must also have a special push-pull slicer. Application of dental paraffin and paraffin section method to solve the problem of the clarity of the structure, sliced with a common slicer. However, the production steps are complicated and not economical.
