- Diversity in dental clinical characteristics in portuguese and spanish military populationsPublication . Guimarães, Maria Inês; Martínez Chicón, Jesús; Gonçalves, Joaquim; Carneiro De Sousa Pinto Costa, Maria José; Márquez Ruiz, Ana Belén; Valenzuela Garach, AuroraIntroduction Dental characteristics were compared in population samples of Spanish and Portuguese military personnel. The main aim of this study was to identify those dental characteristics that could potentially serve to differentiate between these populations in a forensic analysis. Material and methods A sample of 5136 individuals belonging to the professional military staff of the Portuguese and Spanish armed forces was studied. Dental data were recorded with the Forensic Dental Symbols® for the Dental Encoder® database. The population sample analysed in this study consisted of 68.1% Spanish and 31.9% Portuguese individuals. Results The population was mostly male, with 86.6% men (88.1% in the Spanish sample versus 83.4% in the Portuguese sample), and 13.4% women (11.9% Spanish and 16.6% Portuguese). The frequency of unrestored teeth was lowest for first molars in all quadrants, and the highest frequency of unrestored teeth (>90%) was for the upper and lower anterior teeth and lower first premolars. The highest frequencies of restorative treatment were found for the first and second molars in all quadrants, and the highest frequencies of missing teeth were found for the third molars (always >28%). Concordance analysis showed that correlations between contralateral teeth were significantly higher than between antagonist teeth in both samples. Conclusions Our findings provide potentially useful information on the importance of dental record databases and their value for identification purposes.
- Dental diversity patterns: relevance in portuguese military populationPublication . Guimarães, Maria Inês; Gonçalves, Joaquim; Carneiro De Sousa Pinto Costa, Maria José; Valenzuela Garach, AuroraThis research’s purpose was to build a dental database of a Portuguese military population, to know the frequency and distribution of different medical conditions or pathologies found in each dental piece. In order to meet the goals, this study was based on a sample of 1636 professional military people of the Portuguese Armed Forces. Dental data was collected using the Forensic Dental Symbols® and Dental Encoder® database, Microsoft Excel, and SPSS v.23. Teeth were named following the FDI notation system. The analyzed sample population was composed of 83.4% of men and 16.6% of women. The age group with most individuals was 23 - 27 years with a frequency of 32%. The most frequent code in the 32 teeth was “unrestored”. The younger group (≤32 years) had healthier teeth and less missing teeth. Although inconclusive, the dental condition allows individuals classification based on age. The short variability of dental conditions found in the sample, which reflects the population under study, restricts the analysis and, hence, the number of inferences that could be drawn. Studying more heterogenic populations could provide more conclusive results and extraction of additional knowledge from the sample.
