Objetivos: Relacionar a quantidade de gengiva queratinizada com a saúde periodontal em pacientes periodontalmente sãos.
Materiais e Métodos: Foi realizado um estudo observacional em 31 participantes periodontalmente saudáveis. Foram avaliados um total de 870 dentes. Recorrendo a uma sonda periodontal foi quantificado, em milímetros, a faixa de gengiva queratinizada vestibular correspondente a cada dente na sua localização média. Foi medido ainda, caso exista recessão, a distância entre a margem gengival e a junção amelo-cementária. A espessura da gengiva a nível marginal foi caracterizada como sendo fina ou espessa, através da inserção da sonda no sulca e de esta ser ou não visível à transparência, respetivamente. Foi avaliada a relação a quantidade de gengiva queratinizada e a posição do dente na arcada, entre a quantidade de gengiva queratinizada e inflamação gengival, quantidade de gengiva aderida e inflamação gengival, quantidade de gengiva queratinizada e recessões gengivais, quantidade de gengiva queratinizada e espessura do periodonto, espessura do periodonto e inflamação gengival, espessura do periodonto e recessões gengivais. A análise estatística e representações gráficas foram realizadas através da base de dados SPSS. Para a avaliação da relação entre as variáveis em estudo foram realizados os testes estatísticos de Phi e Cramer’s V.
Resultados: Foi observada uma relação estatisticamente significativa entre a quantidade de gengiva queratinizada e a presença de inflamação gengival, entre a quantidade de gengiva aderida e inflamação gengival e entre a quantidade de gengiva queratinizada e a presença de recessões gengivais.
Conclusão: Os locais com menos de 2 mm de gengiva queratinizada e menos de 1mm de gengiva aderida têm uma tendência significativa a apresentarem inflamação gengival. Os locais com uma menor quantidade de gengiva queratinizada estão associados com a presença de recessões gengivais.
Objectives: To relate the amount of keratinized gingiva with periodontal health in periodontally healthy patients. Materials and Methods: An observational study was performed on 31 periodontally healthy participants. A total of 870 teeth were evaluated. Using a periodontal probe, the amount of buccal keratinized gingiva corresponding to each tooth at its middle location was quantified in millimeters. In the presence of gingival recession, the distance between the gingival margin and the cement-enamel junction was measure. The thickness of the gingiva at the marginal level was characterized as being thin or thick, by inserting the probe into the groove and whether or not it is visible to the transparency, respectively. The relationship between the amount of keratinized gingiva and the position of the tooth in the arch, the amount of keratinized gingiva and gingival inflammation, the amount of attached gingiva and gingival inflammation, the amount of keratinized gingiva and gingival recessions, the amount of keratinized gingiva and the periodontal thickness, the periodontal thickness and gingival inflammation, the periodontium thickness and gingival recessions. Statistical analysis and graphical representations were performed through the SPSS database. For the evaluation of the relationship between the variables under study, the statistical tests of Phi and Cramer's V were performed. Results: A statistically significant relationship was observed between the amount of keratinized gingiva and the presence of gingival inflammation, between the amount of attached gingiva and gingival inflammation, and between the amount of keratinized gingiva and the presence of gingival recessions. Conclusions: Locations with less than 2 mm of keratinized gingiva and less than 1 mm of attached gingiva have a significant tendency to present gingival inflammation. Locations with a lower amount of keratinized gingiva are associated with the presence of gingival recessions.
