Precocious puberty indicates quick growth inception and delayed puberty indicates retardation in growth. This study aimed to investigate whether dental development is synchronous with somatic development.
In this study, 62 girls and 34 boys with precocious puberty aged 5 to 9, 29 girls with delayed puberty aged 13 to 16, and 43 boys with delayed puberty aged 14 to 17; 169 children (91 girls and 78 boys) with normal development were compared about their dental ages through their panoramic radiographs by using the Demirjian method and skeletal ages from hand-wrist radiographs by using Greulich-Pyle atlas.
The findings showed that, in all cases, the dental age values were higher than chronologic and skeletal age values to a statistically significant degree. In the precocious puberty group, the dental age values were higher than chronologic age values to a statistically significant degree. In the delayed puberty group, the difference determined between the chronological age and the dental age was not found to be statistically significant.
Given that the Demirjian method is inclined to make calculations that are higher than the chronological age, our findings suggest that the dental development was faster in the precocious puberty group and retarded in the delayed puberty group.
性早熟表明生长开始迅速,青春期延迟表明生长迟缓。本研究旨在调查牙齿发育是否与身体发育同步。
在本研究中,纳入了62名5至9岁的性早熟女孩、34名5至9岁的性早熟男孩、29名13至16岁的青春期延迟女孩以及43名14至17岁的青春期延迟男孩;通过全景X线片使用Demirjian方法比较了169名发育正常的儿童(91名女孩和78名男孩)的牙齿年龄,并通过手腕X线片使用Greulich-Pyle图谱比较了骨骼年龄。
研究结果表明,在所有情况下,牙齿年龄值均高于实际年龄和骨骼年龄值,且具有统计学意义。在性早熟组中,牙齿年龄值高于实际年龄值,具有统计学意义。在青春期延迟组中,实际年龄与牙齿年龄之间的差异未发现具有统计学意义。
鉴于Demirjian方法倾向于得出高于实际年龄的计算结果,我们的研究结果表明,性早熟组的牙齿发育较快,青春期延迟组的牙齿发育较慢。
