In forensic sphere and clinical dentistry, age estimation is a topic of utmost importance. Various techniques are employed in children to determine age; however, dental development has proven to be an appropriate method because of its low variability. Cameriere's method is a widely accepted method of age estimation in children, which is carried out by measuring the projections of open apices and also the heights of developing permanent teeth seen on panoramic radiographs. The aim of this study is to establish a new formula for age estimation in the Western Indian population by measuring the open apices of mandibular teeth using Cameriere's European formula. For this study, we included 311 panoramic radiographs of healthy children living in Western India (Maharashtra, Gujarat, and Goa) aged 4-15 years which were analysed by two independent researchers. Seven left permanent mandibular teeth were assessed for length and width of open apices. Dental maturity was evaluated using measurements of the left seven permanent mandibular teeth ( = / , = 1,…, 7), the sum of the normalized open apices (), and the number (0) of teeth with complete root formation. A linear relationship between open apices, 0, age, and other factors was evaluated with the aid of a stepwise multiple regression model. A stepwise linear regression showed that all parameters, gender, , 0, and , were significantly associated with age ( = 85%). No statistically significant difference was found between the predicted and actual chronological age of children in the age group of 4-13 years using the regression equation for the Western Indian population. The present research suggests that the new regression formula developed will be more accurate for age assessment in the Western Indian population.
在法医学领域和临床牙科中，年龄估计是一个极其重要的话题。在儿童中采用了各种技术来确定年龄；然而，牙齿发育已被证明是一种合适的方法，因为其变异性较低。卡梅里埃方法是一种被广泛接受的儿童年龄估计方法，它通过测量全景X线片上开放根尖的投影以及正在发育的恒牙的高度来进行。本研究的目的是通过使用卡梅里埃的欧洲公式测量下颌牙齿的开放根尖，为西印度人群建立一种新的年龄估计公式。在本研究中，我们纳入了311张居住在印度西部（马哈拉施特拉邦、古吉拉特邦和果阿邦）的4至15岁健康儿童的全景X线片，由两名独立研究人员进行分析。对七颗左侧下颌恒牙的开放根尖的长度和宽度进行了评估。使用左侧七颗下颌恒牙的测量值（ = / ， = 1，…，7）、标准化开放根尖的总和（）以及牙根完全形成的牙齿数量（0）来评估牙齿成熟度。借助逐步多元回归模型评估开放根尖、0、年龄和其他因素之间的线性关系。逐步线性回归表明，所有参数，即性别、、0和，均与年龄显著相关（ = 85%）。使用针对西印度人群的回归方程，在4至13岁年龄组儿童的预测年龄和实际年龄之间未发现统计学上的显著差异。本研究表明，所开发的新回归公式在西印度人群的年龄评估中将更加准确。
