为了研究牙、颌骨及牙周组织的正常结构及其病理变化,必须将其制成薄切片,通过染色等技术处理,才能达到观察组织形态的目的。由于牙齿和骨组织都是钙化的硬组织,特别是牙釉质是高度钙化的硬组织,不脱钙是无法切片的。口腔组织标本要求既要看清牙和骨组织,又要看清软组织,而且在切片中要求能尽量保持原有的骨与软组织之间的关系。而传统的制作方法是用 In order to study the normal structure of the teeth, jawbone and periodontal tissues and their pathological changes, they must be made into thin sections and processed by staining and other techniques to achieve the purpose of observing the morphology of the tissues. Since both tooth and bone tissue are calcified hard tissues, especially enamel is a highly calcified hard tissue that can not be sectioned without decalcification. Oral tissue specimens require both to see the teeth and bone tissue, but also to see the soft tissue, but also in the slice required to try to maintain the original relationship between bone and soft tissue. The traditional method of making is to use
