Abstract

Aim: This study aimed to test the applicability of the methods proposed by Olze et al. (2012) and Timme et al. for dental age estimation in Brazilian subadults and adults. Material and methods: Panoramic radiographs of 503 individuals aged between 20 and 70 years were analyzed. The mean chronological age of males and females of the sample was 29.04 and 29.97 years, receptively. Secondary dentin formation, cementum apposition, periodontal recession, and attrition of teeth #34, #35, #44 and #45 teeth were assessed as parameters to be calculated in the formulae designed by Olze et al. and Timme et al. Results: In males, the mean estimated age by the Olze method was 28.97 ± 2.86 years, while in females it was 27.85 ± 2.70 years. The Timme method estimated mean age for males of 32.54 ± 5.32 years and for females 33.09 ± 5.16 years. Low coefficients of determination (r 2 ) for the application of tooth-specific formulae of both methods suggest that estimated and chronological ages were not properly associated. Conclusion: The outcomes of this study indicate that the Olze and Timme methods may be limited for forensic applications in Brazilian subadults and adults. Country-specific statistical adjustments might be useful for improvements in practice<br />Cilj: Željela se ispitati primjenjivost metoda koje su predložili Olze i suradnici (2012.) i Timme i su-radnici za procjenu dobi zuba brazilskih adolescenata i odraslih. Materijal i metode: Analizirane su panoramske rendgenske snimke 503 osoba u dobi od 20 do 70 godina. Prosječna kronološka dob muškaraca i žena u uzorku bila je receptivno 29,04 i 29,97 godina. Sekundarni dentin, apozicija ce-menta, parodontna recesija i trošenje zuba #34, #35, #44 i #45 ocijenjeni su kao parametri koje treba izračunati u formulama koje su osmislili Olze i suradnici i Timme i suradnici. Rezultati: Kod muškaraca je srednja dob procijenjena Olzeovom metodom bila 28,97 ± 2,86 godina, a kod žena je iznosila 27,85 ± 2,70 godina. Timmeovom metodom procijenjena je srednja dob za muškarce od 32,54 ± 5,32 godine, a za žene 33,09 ± 5,16 godina. Niski koeficijenti determinacije (r 2 ) za primjenu formula specifičnih za zube u objema metodama sugeriraju da procijenjena i kronološka dob nisu pravilno povezane. Zaključak: Rezultati ove studije pokazuju da Olzeova i Timmeova metoda mo-gu biti ograničene kad je riječ o forenzičkoj primjeni kod brazilskih adolescenata i odraslih osoba. Statističke prilagodbe za pojedine zemlje mogle bi biti korisne za poboljšanja u praksi.
