Objective: Chronic kidney failure (CKF) is a progressive deterioration of the kidneys. The goal of this study was to analyze the oral manifestation of CKF in a sample of hemodialysis and transplanted patients. Methods: Eighty-three records of patients treated in the Pro-Renal Foundation in Curitiba, Brazil were used. The records were separated in four groups: Transplanted Men (TM = 14), Transplanted Women (TW = 18), Men in Hemodialysis (MHD = 28) and Women in Hemodialysis (WHD = 23). Information about oral and systemic health condition were collected. Data from each group were submitted to correspondence analysis and quantitative variables were compared by Kruskal-Wallis and Dunn's test. Significance level was 0.05. Results: Gingival inflammation, loss of periodontal support tissue, dental calculus and increase in periodontal probing depth were common findings in all patients, but significant association was found in following groups: TM presented dental calculus; TW presented a high prevalence of cardiovascular problems and saburral tongue; MHD presented poor oral hygiene, gingivitis associated with smoking; WHD presented a high prevalence of temporomandibular dysfunction. Conclusions: The most prevalent findings were increase in the periodontal probing depth and gingival recession. Unexpectedly, WHD group presented a high prevalence of temporomandibular dysfunction.Key words: Hemodialysis; Chronic kidney failure; Oral health Manifestações bucais em pacientes portadores de doença hepática crônica ResuMO Objetivo: Insuficiência Renal Crônica (IRC) é caracterizada pela perda progressiva dos rins. O objetivo deste estudo foi analisar as manifestações bucais de uma amostra de pacientes renais transplantados ou que faz hemodiálise. Metodologia: Oitenta e três prontuários de pacientes em atendimento na Fundação Pró-Renal em Curitiba, Brasil foram analisados e quarto grupos foram formados: Homens Transplantados (HT=14), Mulheres Transplantadas (MT=18), Homens em Hemodiálise (HH=28) e Mulheres em Hemodiálise (MH=23). Informações sobre a saúde bucal e sáude geral foram coletadas. Dados de cada grupo foram submetidos à análise pelo teste Kruskal-Wallis, seguido pelo teste de Dunn com nível de significância de 0,05. Resultados: Inflamação gingival, perda de tecido periodontal de suporte, cálculo dentário e aumento de profundidade de sondagem foram encontrados em todos os pacientes, mas associações significantes foram encontradas nos seguintes grupos: HT apresentaram alta prevalência de cálculo dentário; problemas cardiovasculares e língua saburosa foi observada em MT; HH são fumantes, apresentam probre higiene bucal e gengivite; em mulheres em hemodiálise foi relatada uma alta prevalência de disfunção temporomandibular. Conclusão: Em geral, os achados mais comuns são aumento de profundidade de sondagem e recessão gingival. Mulheres que realizam sessões de hemodiálise apresentam disfunção tempormandibular.
