Comparison of the Cameriere's third molar maturity index and Olze et al.’s stages of radiographic visibility of the root pulp in a Turkish population

Abstract

Purpose: 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. Materials and Methods: 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. Results: 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. Conclusion: 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.

Cameriere'nin üçüncü molar olgunluk indeksi ile Olze ve ark.'nın kök pulpasının radyografik görünürlük aşamalarının Türk popülasyonunda karşılaştırılması

Abstract

Amaç: Reşit olma yaşı, bireyin çocukluktan yetişkinliğe geçiş yaşı olup, hukuki öneme sahiptir. Türkiye'de reşit olma yaşı 18'dir. Yasal yetişkinlik yaşı olan 18 yaşında halen gelişmekte olan üçüncü azı dişleri diş yaşını tahmin etmek için kullanılabilir. Bu çalışmanın amacı, Türk popülasyonunda olgunluk yaşını tahmin etmek için Cameriere'nin üçüncü molar olgunluk indeksini ve Olze ve ark.'nın kök pulpunun radyografik görünürlük aşamalarını karşılaştırmaktı. Gereç ve Yöntem: Bu çalışma, 15-22 yaş arası çocuk ve yetişkin hastalardan alınan 705 panoramik radyografi üzerinde yapılmıştır. Bulgular: Cameriere üçüncü molar olgunluk indeksi erkeklerde %0,77 duyarlılık ve %0,96 özgüllük, kadınlarda %0,57 duyarlılık ve %0,92 özgüllük gösterdi. Olze ve ark.’nın evre 0'ının duyarlılık ve özgüllük sonuçları erkeklerde sırasıyla %0,86 ve %0,79, kadınlarda %0,85 ve %0,75 olarak bulundu. Sonuç: Her iki yöntem de 18 yaş altı ve üstü bireyleri ayırt etmek için uygulanabilse de, Cameriere tarafından önerilen cut-off değeri daha yüksek oranda tip 2 hata (yanlış negatiflik) üretmiştir. Bu nedenle, Olze ve ark.'nın kök pulpasının radyografik görünürlülüğü yöntemi, Türk popülasyonunda yetişkinler ve küçükler arasında ayrım yapmak için kullanılabilir.
