The purpose of this study was to compare the Cameriere's third molar maturity index and Olze et al.'s stages of radiographic visibility of the root pulp in estimating the age of maturity in the Turkish population. The age of majority, which is legally significant, marks the transition from childhood to adulthood. In Turkey, the age of majority is set at 18 years. As the third molars continue to develop at this age, they can serve as an indicator of dental age.
A total of 705 panoramic radiographs obtained from individuals aged 15 to 22 years, including children and adults, were included in this study. The left mandibular third molars were evaluated on panoramic radiographs using Cameriere's third molar maturity index and Olze's method of radiographic root pulp visibility (RPV) stages. Minimum and maximum values were noted for each stage, and a median with upper and lower quartiles, as well as mean and standard deviation were calculated. Sensitivity and specificity values were calculated.
In males, Cameriere's third molar maturity index demonstrated a sensitivity of 0.77% and specificity of 0.96%, while in females, it showed a sensitivity of 0.57% and specificity of 0.92%. Regarding Olze et al.'s stage 0, the sensitivity and specificity values were 0.86% and 0.79% in males, and 0.85% and 0.75% in females, respectively.
Although both methods can be used to distinguish individuals below or above the age of 18, the cut-off value suggested by Cameriere's method resulted in a higher rate of type 2 error (false negativity). Therefore, the method proposed by Olze et al., based on the radiographic visibility of the root pulp, can be employed to differentiate between adults and minors in the Turkish population.
本研究旨在比较卡梅里埃第三磨牙成熟度指数和奥尔泽等人的牙髓放射影像学可见度分期,以评估土耳其人群的成熟年龄。具有法律意义的成年年龄标志着从儿童期到成年期的转变。在土耳其,成年年龄设定为18岁。由于第三磨牙在这个年龄仍在继续发育,它们可以作为牙龄的一个指标。
本研究纳入了705张从15至22岁个体(包括儿童和成人)获取的全景X线片。使用卡梅里埃第三磨牙成熟度指数和奥尔泽的牙髓放射影像学可见度(RPV)分期方法,在全景X线片上对左下颌第三磨牙进行评估。记录每个阶段的最小值和最大值,并计算中位数以及上四分位数和下四分位数,同时计算均值和标准差。计算敏感度和特异度值。
在男性中,卡梅里埃第三磨牙成熟度指数的敏感度为0.77%,特异度为0.96%;在女性中,其敏感度为0.57%,特异度为0.92%。关于奥尔泽等人的0期,男性的敏感度和特异度值分别为0.86%和0.79%,女性分别为0.85%和0.75%。
虽然两种方法都可用于区分18岁以下或以上的个体,但卡梅里埃方法建议的截断值导致更高的Ⅱ型错误率(假阴性)。因此,基于牙髓放射影像学可见度的奥尔泽等人提出的方法,可用于区分土耳其人群中的成年人和未成年人。
