Abstract: Objective:To analyze the hard tissue thickness in the crown of primary teeth by CBCT.Methods:The CBCT imaging data of 47 children were included,and the hard tissue thickness of primary teeth was measured by MIMICS software.SPSS 22.0 was used for data analysis.Results:The average thickness in the mesial surfaces was the smallest(P＜0.01),except for the libial surface of maxillary central incisor and the distal surface of mandibular first primary molar.In primary anteriors,the thickness in the same sur-face of maxillary teeth was greater than that of mandibular teeth significantly(P＜0.01)except for the libial surface of primary canine.In primary molars,the thickness of hard tissue in the same part of the distal and lingual side of the maxillary teeth was greater than that of the mandibular teeth(P＜0.01),and the thickness in the buccal side of maxillary teeth was lower than that of the mandibular teeth(P＜0.01).Conclusion:The distribution of hard tissue thickness of primary teeth in different position is different.
