ASSESSMENT OF DENTAL DIVERSITIES ON PANORAMIC RADIOGRAPHS FOR HUMAN IDENTIFICATION: A RETROSPECTIVE STUDY

ABSTRACT Aim: The correct identification of a person after death is an important process with respect to moral, social and legal consequences. The aim of this study is to evaluate the diversity of dental patterns, which is seen in dental panoramic radiographs for personal identification in the Turkish population. Materials and Methods: Five hundred and three radiographs were randomly selected from the patient database of different 3 private dental clinics. Teeth observed on the dental radiographs about seventeen major dental patterns for each tooth by a well-trained dentist. Generally, permanent dentition was considered for major evaluation for the patient older than 18 years of age and dentulous or partially edentulous. Each radiograph was matched to the sex, age and educational status of every individual. Results: Distributions of observed population were 57.3% female, 42.7 male; 66.4% young, 30.2% middle age, 3.4% old; and 40.2% primary-educated individual, 59.8% high-educated individual. The dental pattern data were grouped and analyzed by categorical data analysis and experimental design. The most observed dental patterns were virgin tooth (54.98%) in all cases. The missing tooth (13.46%) and dental fillings (11.45%) followed virgin tooth respectively. However, other the least commonly observed 14 dental patterns were showed lower than 5% frequency. Conclusion: The healthy teeth are mostly observed in the lower anterior sextant in both male and female. In young adults, the present a more balanced distribution compared to other age groups. Also, the people with low education have more rarely healthy teeth in the upper and lower molar regions according to odds-ratios.

OZET INSANLARIN KIMLIKLENDIRILMESINDE PANORAMIK RADYOGRAFILER UZERINDEN DENTAL CEŞITLILIKLERIN DEĞERLENDIRILMESI: RETROSPEKTIF CALIŞMA Amac: Olum sonrasinda bireyin dogru sekilde kimliklendirmesinin yapilmasi her toplum icin dini, ahlaki, sosyal ve yasal bir zorunluluktur. Bu calismanin amaci ornekleme yapilan Turk populasyonun dental nedenlerle daha onceden alinmis panoramik dis filmleri uzerinden dental durumlarinin degerlendirilerek kimlik tespitinin yapilip yapilamayacaginin degerlendirilmesidir. Gerec ve Yontem: Uc farkli dis muayenehanesinden daha once teshis ve tedavi amaciyla hekimlerin talep ettigi ve hasta arsivinde bulunan toplam 503 dental panoramic radyografi rastgele secilmistir. Iyi egitimli bir dis hekimi tarafindan bu radyografiler uzerinden 17 temel dental durum ayri ayri sayisal olarak analiz edilmistir. Secilen radyografilerin ait oldugu hastalarin 18 yasindan buyuk olmasina ve tam dissizlik durumunun bulunmamasina dikkat edilmistir. Her radyografi, sahibinin yasi, cinsiyeti ve egitim durumuyla da eslestirilmistir. Bulgular: Orneklemde kullanilan populasyonun % 57.3’u kadin, % 42.7’si erkek; % 66.4’u genc, % 30.2’si orta yasli, % 3.4’u yasli ve % 40.2’si ilk ogretim seviyesinde egitimli, % 59.8’i de lise ve ustu egitim almis olarak tespit edilmistir. Tum vakalar icin en fazla gozlenen durum %54.98 olarak saglikli dis varligidir. Bunu sirasiyla %13.46 olarak dis eksikligi ve %11.45 olarak dolgu izlemektedir. Diger dental durumlarin %5 sikligin altinda oldugu tespit edilmistir. Sonuc: Hem hadin hem de erkeklerde en fazla saglikli disler alt on bolgede gorulmektedir. Genc bireylerdeki saglikli dis dagilimi diger yas gruplarina gore daha dengelidir. Odds orani dikkate alindiginda da diger gruplardan farkli olarak dusuk egitim seviyesine sahip bireylerde molar bolgelerde saglikli dise daha nadir rastlandigi gozlenmistir.
