牙齿纵折是指牙齿循长轴的折裂。许多学者已通过临床病例观察、动物实验对其发病因素、临床特征及治疗进行了探讨和分析。本文的目的是通过对50个拔除的纵折后牙的离体观察、结合临床资料来探讨和分析后牙纵折的特征和有关病因学因素。材料和方法在拔牙室随机收集纵折后牙50个。拔牙前进行记录;牙齿拔除后迅速固定在10％福尔马林液或4％的戊二醛液中。然后先用肉眼观察患牙的形态、修复和折裂等情况,再在解剖显
Teeth longitudinal fold refers to the long axis of tooth fracture. Many scholars have been through clinical case observation, animal experiments on the incidence of factors, clinical features and treatment were discussed and analyzed. The purpose of this paper is to investigate and analyze the characteristics of posterior longitudinal folds and related etiological factors through the in vitro observation of 50 extracted longitudinal folds and the clinical data. Materials and Methods 50 longitudinal extraction teeth were collected in the extraction room. Tooth extraction before extraction; dental extraction quickly fixed in 10% formalin or 4% glutaraldehyde solution. Then first with the naked eye to observe the shape of the teeth, repair and fracture, etc., and then in the anatomical significant
