Understanding sexual maturity and bone fusion is crucial in forensic investigations and legal contexts. This study investigates the contemporary trend of sexual maturity and bone fusion in females, comparing the observed age-related characteristics with documented ages. Such analyses contribute to the accuracy of age estimation methods used in medico-legal scenarios.
A comprehensive study was conducted involving a diverse sample of females, and their sexual maturity and bone fusion were assessed relative to documented ages. The research utilized a cross-sectional design, collecting data through interviews, medical examinations, and radiographic imaging. Ethical approval was obtained, and participants provided informed consent. Variables included documented age, age of menarche, stages of sexual maturity, dentition, and bone fusion. Validation of model performance was conducted.
Among 70 cases studied, the mean age of menarche was 10.48 years (range: 7-12 years). Maternal reports indicated menarche onset between 12-17 years. Tanner's Staging 5 for pubic hair and fully developed breasts occurred at 14 years. Permanent teeth increased with age, with 28 or more teeth present at age 14 or above. Fusion of the distal end of the Radius and Ulna with the parent bone was positive from 15 years onwards. The regression model predicted age accurately (97.99% fit).
The results highlight the early onset of sexual maturation, consistent teeth eruption, and bone fusion patterns in females. The observed correlations offer valuable insights for medicolegal practitioners and forensic experts.
了解性成熟和骨骼融合在法医调查和法律背景中至关重要。本研究调查了女性性成熟和骨骼融合的当代趋势,将观察到的年龄相关特征与记录的年龄进行比较。此类分析有助于提高法医场景中年龄估计方法的准确性。
进行了一项全面研究,涉及不同的女性样本,并根据记录的年龄评估她们的性成熟和骨骼融合情况。该研究采用横断面设计,通过访谈、医学检查和影像学检查收集数据。获得了伦理批准,参与者提供了知情同意。变量包括记录的年龄、初潮年龄、性成熟阶段、牙列和骨骼融合情况。对模型性能进行了验证。
在研究的70例病例中,初潮的平均年龄为10.48岁(范围:7至12岁)。母亲报告显示初潮发生在12至17岁之间。阴毛和乳房完全发育的坦纳5期出现在14岁。恒牙随着年龄增长而增加,14岁及以上有28颗或更多牙齿。桡骨和尺骨远端与母体骨骼的融合从15岁开始呈阳性。回归模型准确预测了年龄(拟合度为97.99%)。
结果突出了女性性成熟、牙齿萌出一致和骨骼融合模式的早期开始。观察到的相关性为法医从业者和法医专家提供了有价值的见解。
