Introdução: Para além da cor dos dentes, a cor da gengiva tem um papel muito importante na reabilitação protética do sector anterior do maxilar, sempre que é necessário substituir tecidos moles ausentes. A cor destes tecidos periodontais não é fácil de definir, variando de tons rosa para tons mais avermelhados ou acastanhados, por exemplo. Tendo em consideração esta dificuldade de caracterizar a cor da gengiva, definiu-se como objectivo deste estudo determinar a cor da gengiva aderida, zona de transição e gengiva livre de indivíduos caucasianos.
Metodologia: Procedeu-se à realização de questionários onde se recolheram os dados demográficos, hábitos alimentares e de higiene oral dos participantes. A amostra foi constituída por 50 indivíduos, (30 (60%) são do sexo feminino e 20 (40%) são do sexo masculino). Realizaram-se também fotografias intra-orais frontais a todos, posteriormente foram analisadas no programa informático Adobe Photoshop® por forma a recolher os dados referentes a uma escala de cores (CIELab).
Resultados: O género influencia a alteração de cor da gengiva sendo que a dos homens tem maiores quantidades de amarelo do que de azul ao avaliarmos a cor pela escala CIELab. O consumo de tabaco influencia a luminosidade da gengiva, sendo que a gengiva dos fumadores tem menos luminosidade. A higienização, neste estudo não tem influência na cor da gengiva. Não foi possível aferir significativamente a relação entre o consumo de café e a sua influência na cor da gengiva nem a utilização de restauração protética.
Conclusão: O sexo, o consumo de tabaco e o consumo de alimentos ácidos influenciam a cor da gengiva. Devemos então alertar os pacientes para o consumo excessivo do tabaco e de alimentos ácidos.
Introduction: In addition to the color of teeth, gingiva color has a very important role in the prosthetic rehabilitation of the anterior maxillary sector, when the replacement of missing soft tissue is necessary. The color of the periodontal tissue is not easy to define, varying shades of pink for more reddish or brownish, for example. Taking into account the difficulty of characterising the gum color, the objective set on this study was to determine the color of attached gum, transition zone and free gum in Caucasians individuals. Methodology: The procedure was made with the help of questionnaires. From these, demographic, eating habits and oral hygiene data of the participants were collected. The sample consisted of 50 individuals, of which 30 (60%) were female and 20 (40%) were male. Front intraoral photographs of all of them were taken and later analyzed by Adobe Photoshop® software, collecting data for a range of colors (CIELab). Results: It was found that the gender influences the change of gum color. When evaluated by the CIELab scale, men have larger amounts of yellow and less of blue. Tobacco consumption reduces gums brightness. According to the statistic analysis, dental hygiene doesn't influence gum color. The relationship between the use of prosthetic devices and the coffee consumption and their influence in gum color couldn't be accessed on this study. Conclusion: The gender, the tobacco and acidic foods consumption influences the color of the gingiva. We must alert patients for the aesthetic consequences of their excessive consumption.
