| 内容記述 | To elucidate the eruptive conditions and dentition of the deciduous molars and the first molars during the early mixed dentition period (dental age IIIA), tooth crown and gingival morphology in the dental plaster casts was measured using a three-dimensional shape measurement system (CUBESPER CD-100). Upper and lower dental plaster casts obtained from 22 children were used as the materials for measurement, and extracted teeth (10 teeth per tooth type) were used as the measurement reference. The results were as follows : 1. With regard to the vertical distance between the cervical points and the reference plane, the cervical points on the buccal side were more superior in the first molars than in the deciduous molars both in the maxilla and mandible. The cervical points on the lingual side in the mandibular teeth were more inferior in the order of the deciduous first molars <the deciduous second molars <the first molars, showing increases in the vertical distance. Furthermore, the cervical point on the buccal side was more superior to that on the lingual side in the first molars both in the maxilla and mandible, showing large vertical positional differences. The differences were marked in the mandibular teeth. 2. The eruptive rate was approximately 62-70% in the deciduous molars, showing slightly higher values on the buccal side in the mandibular deciduous first molars, and on the lingual side in the mandibular deciduous second molars. On the other hand, the eruptive rate was approximately 50-60% in the first molars, showing lower values in comparison with the deciduous molars. 3. The coronal axial inclination was approximately 93-94° in the maxillary deciduous first and second molars, showing a slight buccal inclination. It was approximately 82-87° in the mandibular deciduous first and second molars. showing a slight lingual inclination. On the other hand. the coronal axial inclination was approximately 98° in the maxillary first molars, showing more buccally inclined angles than the deciduous molars, and it was approximately 73° in the mandibular first molars, showing more lingually inclined angles than the deciduous molars. 4. The tooth surface inclination on the lingual side was lower in the first molars than in the deciduous molars in the maxilla. The buccal surface inclination in the mandibular molars was lower in the order of the deciduous first molars> the deciduous second molars> the first molars, and the lingual surface inclination was higher in the order of the deciduous first molars <the deciduous second molars <the first molars. These results revealed the characteristics of the eruptive conditions and dentition of the deciduous molars and the first molars during the mixed dentition period in children. It was suggested that the eruptive position and bucco-lingual surface inclination in the first molars markedly differed from those in the deciduous molars. These findings were considered important to develop healthy permanent dentition and occlusion, to evaluate appropriate oral management and hygiene methods, and to perform caries treatment. | |||||
