Muertes por arma de fuego y disparo intraoral: etiología medicolegal

Investigation of deaths caused by the use of firearms, with their different homicidal, suicidal and accidental etiologies, is part of the medical-forensic expert's regular work. Mouth is usually chosen by the suicide using a gun. However, gunshot rarely occurs -or it is an exception, in homicidal or accidental deaths. In this paper we shall review the different variables which are useful in order to discriminate the different etiologies, such as the scene, the kind of weapon used, the number of injuries sustained and their location, or the direction of the bullet. Also, we shall particularly focus on the types of injuries caused. The way that lips, teeth and tongue are affected is of particular interest in this investigation. For this purpose, we have conducted a research in books and medical articles, including the PubMed, Dialnet y Academic Google bibliographic database.
