Dental Ritual Mutilations and Forensic Odontologist Practice: a Review of the Literature

Uvod: Etnička sakaćenja imaju antropološko značenje, kako u suvremenom tako i u nekadašnjem ljudskom ponašanju, ovisno o geografskim, religioznim i kulturnim čimbenicima koji znatno mogu pomoći forenzičnom stomatologu u postupku izrade dentalnog profila. Sakaćenje zuba i ukrasi na njima bili su, i još uvijek jesu, uobičajeni među mnogim etničkim skupinama i kulturama. Kroz povijest ljudskoga roda zdravlje zuba bilo je simbol mladosti, ljepote i snage, ali može imati i druga značenja. Sakaćenje zuba obilježje je mnogih nestalih kultura i prakticiralo se uglavnom tijekom religijskih rituala, u estetske svrhe i kao simbol pripadnosti određenoj socijalnoj skupini. No slični običaji i danas su uobičajeni u nekim područjima diljem svijeta. Materijali i metode: Članak je zapravo sustavni pregled literature o ritualnom sakaćenju zuba iz ranih 1960-ih, a uključeni su i podatci s PubMeda, Scopusa i Google Scolara. Istaraživanje je namjerno ograničeno na ritualno sakaćenje koje se može definirati kao bilo koje nepovratno narušavanje integriteta ljudskoga organizma učinjeno u ritualne svrhe i bez namjere liječenja. Zato su isključeni svi slučajevi pojedinačnih ili višestrukih samovađenja zuba učinjenih iz psihotičnih razloga te oralno sakaćenje djece jer se takva praksa u nekim etničkim skupinama smatra terapijskom. Zaključak: Spoznaje o promjenama na zubima nakon oralnoga sakaćenja važne su pri identifikaciji živih ili umrlih osoba, ili čak ljudskih ostataka jer odaju odgovarajuće informacije o etničkom i kulturološkom podrijetlu subjekta. U ovom članku navedena su i neka medicinskopravna stajališta o sakaćenju zuba, a namijenjena su doktorima dentalne medicine.Background: Ethnic mutilations have a social and anthropological significance both in contemporary and past human behavior, influenced by geographic, religious and cultural factors which can greatly help forensic odontologist’s practice in dental profiling process. ental ritual mutilations and dental decorations were - and still are - practiced among many ethnic groups and cultures. Throughout the history of humanity, having healthy teeth has a symbolic meaning of youth, beauty and strength, but it can also have other meanings. Dental ritual mutilations were documented in many cultures in the past and were practiced mainly for religious rituals purposes, for esthetic reasons and because they represented a symbol of status or of belonging to a particular social group. Similar rituals are still performed. Material and Method: The present paper is a systematic review of the literature reporting on dental ritual mutilations from the early 1960s and is included in Pubmed, Scopus and Googlescholar. The research was deliberately limited only to the ritual mutilations, which can be defined as “any irreversible impairment of the integrity of the human organism, made with a ritual purpose and without any curative aim”. Therefore all the articles dealing with single or multiple dental self extractions of psychotic origins were excluded, as well as the infant oral mutilations, since the practice is deemed to have therapeutical effects among ethnic groups dedited to this practice. Conclusions: The knowledge of dental alteration due to oral mutilations can be a powerful tool for the identification procedures of living or dead persons or even in human remains especially providing relevant information about the ethnic origins and the cultural background of a subject. Some medical legal issues for the odontologist about dental mutilation are also addressed in the paper

Age estimation by assessment of pulp chamber volume: a Bayesian network for the evaluation of dental evidence

Purpose The present study aimed to investigate the performance of a Bayesian method in the evaluation of dental age-related evidence collected by means of a geometrical approximation procedure of the pulp chamber volume. Measurement of this volume was based on three-dimensional cone beam computed tomography images. Methods The Bayesian method was applied by means of a probabilistic graphical model, namely a Bayesian network. Performance of that method was investigated in terms of accuracy and bias of the decisional outcomes. Influence of an informed elicitation of the prior belief of chronological age was also studied by means of a sensitivity analysis. Results Outcomes in terms of accuracy were adequate with standard requirements for forensic adult age estimation. Findings also indicated that the Bayesian method does not show a particular tendency towards under- or overestimation of the age variable. Outcomes of the sensitivity analysis showed that results on estimation are improved with a ration elicitation of the prior probabilities of age
