Introdução: O fluido crevicular, em locais clinicamente saudáveis, é um líquido intersticial que aparece como um transudado no sulco devido a um gradiente osmótico.
Em locais não saudáveis este fluido pode ser classificado como um exsudado inflamatório produzido pela gengiva inflamada ao nível de sulcos e bolsas. Num periodonto com inflamação, este fluido encontra-se presente em maior volume. É um potencial marcador da severidade da inflamação dos tecidos, podendo o estudo das variações do seu volume auxiliar no diagnóstico e no tratamento da doença periodontal e peri-implantar .
Objetivo: Análise volumétrica comparativa do fluido crevicular nas localizações: dente saudável, dente com periodontite, implante saudável e implante com peri-implantite, para determinar se existem diferenças significativas entre situações de saúde e doença.
Pretende-se também com este estudo avaliar se existem diferenças volumétricas nas localizações com implantes comparativamente a zonas de dentes, nas mesmas condições de saúde e doença.
Materiais e métodos: Foram selecionados 18 pacientes, previamente submetidos a um questionário. Constituíram-se 2 grupos, o grupo de saúde (N=11) e o grupo de doença Periodontal e Peri-implantar (N=10). A recolha do fluido iniciou-se com o isolamento relativo da zona, seguido da inserção de um Periopaper no sulco/bolsa até ser sentida resistência, tendo-se aguardado 30 segundos até à sua remoção. O volume de fluido foi calculado com a inserção do Periopaper no Periotron 8000 (Oralflow Inc., New York, NY, USA). Utilizou-se o teste de Friedman na análise estatística.
Resultados: Na análise comparativa foram identificadas diferenças estatisticamente significativas (p=0,004) na comparação entre dente saudável e implante com periimplantite (p=0,029, teste de Friedman).
Conclusão: O volume de fluido crevicular apresenta-se mais elevado quanto mais severa for a inflamação dos tecidos.
Introduction: In clinical healthy sites, gingival crevicular fluid appears as an interstitial fluid resembling a transudate in the sulcus due to the osmotic gradient. In unhealthy sites, crevicular fluid can be classified as an inflammatory exudate secreted by the inflamed gingiva into the sulcus/pockets. In an inflamed periodontium, this fluid is present in larger volumes. It´s a potential marker of the severity of the inflammation in the site, and the study of its volumetric changes can be pertinent to better diagnose and treat periodontal and peri-implant disease. Objective: Volumetric and comparative analysis of crevicular fluid: healthy tooth, tooth with periodontitis, healthy implant, and implant with peri-implantitis, to determine if there are significant differences between healthy and disease conditions. It is also intended with this study to assess whether there are volumetric differences in locations with implants compared to areas of teeth, in the same health and disease conditions. Materials and methods: 18 patients were selected, previously submitted to a questionnaire, and informed consent. Two groups were constituted, the Periodontal and Peri-implant health group (N=11) and the Periodontal and Peri-implant disease group (N=10). Fluid collection in selected locations began with relative isolation, a Periopaper was inserted in the sulcus/pocket, in which it remained for 30 seconds until its removal. The fluids volume was calculated by inserting the Periopaper into the Periotron 8000 (Oralflow Inc., New York, NY, USA). The Friedman test was used in the statistical analysis. Results: In the comparative analysis, statistically significant differences (p=0.004) were identified in the comparison between healthy tooth and implant with peri-implantitis (p=0.029, Friedman test). Conclusion: The volume of crevicular fluid is higher the more severe the tissue inflammation is.
