FERNANDES, Clemente Maia da Silva; PEREIRA, Frederico David Alencar de Sena; SILVA, Jorge Vicente Lopes da  e  SERRA, Mônica da Costa. Forensic Facial Reconstructions analysis: proposal of a evidence-based pilot protocol. Rev. Assoc. Paul. Cir. Dent. [online]. 2015, vol.69, n.2, pp. 103-118. ISSN 0004-5276.

The forensic facial reconstruction corresponds to the rebuilding of the face of an individual, upon an unidentified skull. It can be two-dimensional or three-dimensional, performed manually or digitally. In the latter case, the advent of new information technologies has greatly contributed, especially with regard to the development of 3D image softwares, computed tomography and 3D scanner. Different techniques, equipments and softwares have been employed for this purpose. The characterization of facial reconstructions with hair, as hair, eyelashes and eyebrows, has been questioned, especially when there is no information about such data. This paper analyzes 3D digital forensic facial reconstructions and, based on evidence, proposes a pilot protocol for their confection and presentation. Digital facial reconstructions, made with 3ds Max software, without hair characterization, were made using three different tables of thickness of soft tissues. They were evaluated by 22 examiners, in a recognition test. In all cases, the target-subject was the most recognized subject, reaching the recognition rate of 45.45%. A proposal for a pilot protocol for the confection and presentation of forensic facial reconstructions is presented. The 3ds Max software is used to perform the facial reconstruction, and the ZBrush software to make the post-production (as wrinkles and lines). A prototype of the facial reconstruction is printed - it can facilitate the recognition of the subject. The authors state that the characterization with hair should not be performed, as it can impair the recognition.
