RESUMO

The maxillaries sinus can supply real value subsidies for the forensic identification. The sinus outlines individuality allows an accuracy and meticulous analysis, reducing the mistakes risks during the expert performance. The aims of this study were: to evaluate the possibility of sex estimate and individual human identification for the maxillaries sinus and to propose three identification methods through referred structures. The sample was composed by 656 panoramic dental radiographs of 328 individuals with 20 years superior age, masculine and feminine. They were divided in controls and experimental groups, in agreement with the absence and presence of dental loss. It was used two radiographs of participants, an initial and other after two years of the orthodontic treatment. Three methods were used: two manual and one computerized. In the manual techniques it was calculated the height and width of the maxillaries sinus, in acetate and took place analysis of those structures morphology, for quadrants. In the computerized it was calculated the area, perimeter and factor in way of the sinus, through the IMAGELAB 2000® software. In the analysis of the results, the descriptive statistics were used (average and standard deviation) and the t-Student test with variances same or unequal and pared t-Student, for the quantitative variables and visual observation of the quadrants morphology of each maxillary sinus. The methods proposed for analysis of the maxillaries sinus showed that the morphology comparison and measurements of these structures in panoramic dental radiographs can be used to estimate of the sex and individual human identification. The dental loss in the experimental group didnt implicate in the dimension of the sinus maxillaries. The incorporation of the sinus maxillaries analysis associated to other evidences is susceptible to be used at the Forensic Institutes, could contribute in a significant way in human identification cases.
