| 内容記述 | In order to investigate the arch dimensions of deciduous dentition, as well as the condition of primary occlusion and crown morphology of deciduous teeth in Chinese children, dental checks and impression of dental plaster models were performed at nursery schools in Shijiazhuang, China. The authors previously reported the deciduous arch dimensions in Chinese children. Based on the same dental plaster models, we conducted the present study was to investigate the crown morphology of mandibular deciduous molars in Chinese children and to compare it with those previously reported for different races. The results were as follows: 1) Regarding the occlusal surface pattern of m_2, 95.1% were type Y and 4.9% were type +; no type X patterns were observed. Sixth cusps were noted in 29.4% of m_2, and seven cusps in 45.1%. 2) Regarding the occlusal surface pattern of m_1 85.7% were type Y, 2.9% were type +, and 11.4% were type X. Among these teeth, 50.5% had four cusps and 49.5% five cusps, and no teeth with six cusps were observed. 3) The frequency of Protostylid on m_2 was 46.5% and the developmental state of the Protostylid was rudimentary in 70.8%, distinct in 23.1%, and well-developed in 6.2%. 4) The frequency of Cingulum on m_2 was 55.3%. 5) For the ratio of anterior and posterior occlusal measurements of nil no significant difference observed between the Chinese children and Japanese children in Hanihara; the index was 49.9 or less in 16.9%, between 50.0 and 67.0 in 64.8%, 67.1 or more in 18.3%. | |||||||
