| Abstract | Dentalna medicina oduvijek je imala veliki značaj u forenzici i antropologiji. Određivanje dentalne dobi pokazalo je odlične rezultate pri procjeni kronološke dobi kako živih tako i mrtvih ispitanika. Metoda po Cameriere-u određuje dentalnu dob pomoću zuba u rastu i razvoju, mjerenjem njihovih širina apeksa.
Cilj: Izračunati dentalnu zrelost hrvatske djece koja žive u splitskoj regiji metodom po Cameriere-u, usporediti je sa kronološkom dobi, te utvrditi koliko je odstupanje kronološke od dentalne dobi.
Materijali i metode: Analizirano je 400 ortopantomograma (OPG) pohranjenih na Odjelu za maksilofacijalnu kirurgiju Kliničkog bolničkog centra Split, 200 muških i 200 ženskih pacijenata dobi od 6 do 15 godina. Prije samog razabira snimaka, isključeni su svi OPT-i osoba sa evidentiranim razvojnim anomalijama i sindromima te stanjima koji utječu na razvoj trajnih zuba. Pregled literature se temeljio na bazi podataka MEDLINE/PubMed. Analiza je provedena softwareom „MS Excell“ i „Coral Draw x8“.
Rezultati: Srednja dentalna dob u cjelokupnom uzorku je statistički značajno podbacila dentalnu dob u odnosu na kronološku u dječaka, -0,11±0,73 godina (p<0,044), dok je razlika za djevojčice bila -0,18±0,70 (p<0,001) godine. Prema dobnim skupinama dentalna dob je prosječno podbacivala u odnosu na kronološku dob, statistički značajan prebačaj dobi je nađen jedino u 6 godišnjih djevojčica i 8 godišnjih dječaka. Razlike dentalne od kronološke dobi nisu bile značajne za većinu dobnih skupina osim u 8, 13, i 14 godišnjih dječaka i 6, 7, 10, 13 i 14 godišnjih djevojčica. Rezultate statističke značajnosti t-testa za dobne skupine od 6 i 14 godina treba uzeti sa rezervom radi malog broja ispitanika. Naknadni (post-hoc) test je pokazao da je statistički značajna razlika bila između dobne skupine dječaka od 8 godina sa dobnom skupinom od 13 godina (p=0,005) i 14 godišnjaka sa svim skupinama od 6 do 12 godina. U djevojčica je statistički značajna razlika bila između skupina od 6 i 10 godina (p<0,043), 13 i 6 godina (p <0,001), 13 i 7 godina (p <0,001), 13 i 8 godina (p =0,001), 13 i 9 godina (p =0,002), 13 i 11 godina (p =0,001), 13 i 12 godina (p=0,048) te 14 godišnjakinja sa svim skupinama od 6 do 12 godina. Srednje apsolutno odstupanje dentalne od kronološke dobi je bilo 0,53±0,52 godina za dječake i 0,55±0,47 godina za djevojčice.
Zaključak: Rezultati pokazuju da metoda po Cameriere-u iz 2007. godine prosječno podbacuje dentalnu dob manje od 6 mjeseci u oba spola osim u dobnim skupinama od 13 i 14 godina, štoje u skladu sa preporukom autora da navedenu metodu treba koristiti u djece mlađe od 13 godina. |
| Abstract (english) | Dental medicine has always had a great significance in forensic science and anthropology. Dental age estimation has shown excellent results in the assessment of chronological age of both the living and the dead examinees. The Cameriere’s method determines dental age by measuring the width of an apex of growing and developing teeth.
Objective: The aim of this study was to calculate the dental maturity of Croatian children from region of Split using Cameriere’s method, compare the results and to determine deviation between chronological and dental age.
Materials and methods: The analysis was made on 400 orthopantomographs (OPG) of 200 male and 200 female patients aged 6 to 15 years, all of which are stored at the Department of Maxillofacial Surgery at the University Hospital Centre Split. Before the selection of radiographs, the OPGs of the patients with developmental anomalies, syndromes, and conditions which affect the development of permanent teeth were excluded. A literature review was based on databaseMEDLINE/PubMed. The analysis was conducted through MS Excell and Coral Draw x8software.
Results: Statistically, mid dental age in the overall sample significantly underestimated dental age when compared to chronological age in boys, -0,11±0,73 years (p<0,044), while the difference for girls was -0,18±0,70 (p<0,001) years. According to age groups, dental age was mostly underestimated when compared to chronological age, overestimation of the age was found only in 6-year-old girls and 8-year-old boys. The differences between dental and chronological ages were not significant for the majority of age groups, except for boys aged 8, 13, and 14, and girls aged 6, 7, 10, 13, and 14. Statistically significant results of the t-test for age groups of 6 and 14 should be interpreted with caution due to the small number of patients. The subsequent (post-hoc) test showed a statistically significant difference between age group of boys aged 8 and age group aged 13 (p=0,005) and between 14-year-old boys and all group ages between 6 and 12. The statistical difference with girls was significant between age groups of 6 and 10 (p<0,043), 13 and 6 (p <0,001), 13 and 7 (p <0,001), 13 and 8 (p =0,001), 13 and 9 (p =0,002), 13 and 11 (p =0,001), 13 and 12 (p=0,048), and 14-year-olds with all group ages between 6 and 12. Mean absolute deviation of dental and chronological age was 0,53±0,52 years for boys and 0,55±0,47 years for girls.
Conclusion: The results show that the Cameriere’s method from 2007 on average underestimates dental age for less than 6 months in both sexes, except for age groups of 13 and 14 years old, which is in accordance with the author’s recommendation to use this method in children younger than 13. |
