INTRODUCTION
In the modern era, identification and determination of age is imperative for diversity of reasons that include disputed birth records, premature delivery, legal issues and for validation of birth certificate for school admissions, adoption, marriage, job and immigration. Several growth assessment parameters like bone age, dental age and the combination of both have been applied for different population with variable outcomes. It has been well documented that the chronological age does not necessarily correlate with the maturational status of a child. Hence, efforts were made to determine a child's developmental age by using dental age (calcification of teeth) and skeletal age (skeletal maturation).
AIM
The present study was aimed to correlate the chronological age, dental age and skeletal age in children from Southeastern region of Andhra Pradesh, India.
MATERIALS AND METHODS
Out of the total 900 screened children, only 100 subjects between age groups of 6-14 years with a mean age of 11.3±2.63 for males and 10.77±2.24 for females were selected for the study. Dental age was calculated by Demirjian method and skeletal age by modified Middle Phalanx of left hand third finger (MP3) method. Pearson's and Spearman's correlation tests were done to estimate the correlation between chronological, dental and skeletal ages among study population.
RESULTS
There was a significant positive correlation between chronological age, dental age and all stages of MP3 among males. Similar results were observed in females, except for a non-significant moderate correlation between chronological age and dental age in the H stage of the MP3 region.
CONCLUSION
The results of the present study revealed correlation with statistical significance (p<0.05) between chronological, dental and skeletal ages among all the subjects (48 males and 52 females) and females attained maturity earlier than males in the present study population.
引言
在现代社会，出于多种原因，年龄的识别和确定至关重要，这些原因包括出生记录有争议、早产、法律问题以及为学校入学、收养、婚姻、工作和移民等目的而对出生证明进行验证。诸如骨龄、齿龄以及两者结合等多种生长评估参数已应用于不同人群，结果各异。有充分文献记载，实足年龄不一定与儿童的成熟状态相关。因此，人们努力通过齿龄（牙齿钙化情况）和骨龄（骨骼成熟度）来确定儿童的发育年龄。
目的
本研究旨在关联印度安得拉邦东南部地区儿童的实足年龄、齿龄和骨龄。
材料与方法
在总共900名筛查儿童中，仅选择了100名年龄在6至14岁之间的受试者，男性平均年龄为11.3±2.63岁，女性平均年龄为10.77±2.24岁用于研究。齿龄通过德米尔坚方法计算，骨龄通过左手第三指中节指骨（MP3）改良法计算。进行了皮尔逊相关性检验和斯皮尔曼相关性检验，以估计研究人群中实足年龄、齿龄和骨龄之间的相关性。
结果
男性的实足年龄、齿龄与MP3的所有阶段之间存在显著正相关。女性也观察到类似结果，但在MP3区域的H阶段，实足年龄与齿龄之间存在不显著的中度相关性。
结论
本研究结果显示，所有受试者（48名男性和52名女性）的实足年龄、齿龄和骨龄之间存在统计学显著相关性（p<0.05），并且在本研究人群中女性比男性成熟得更早。
