Prevalência de traumatismo dentário em pacientes com deficiência atendidos na clínica de pacientes especiais da Universidade Católica de Brasília (UCB)

Introdução No Brasil, o traumatismo dentário (TD) é considerado um problema de saúde pública. No entanto, poucos estudos na literatura relatam a prevalência de TD em pessoas com deficiência (PD). Objetivo O objetivo deste trabalho foi avaliar a prevalência de TD em PD atendidas na Clínica de Pacientes Especiais da Universidade Católica de Brasília (COPE). Material e método Este estudo seguiu um delineamento descritivo e retrospectivo, e foi realizado por meio da análise de 73 prontuários de PD atendidas na COPE entre 2014 e 2016. Foram coletados dados sociodemográficos e clínicos. O teste t foi utilizado entre as proporções para determinar se houve diferenças significativas entre as categorias das variáveis analisadas. O programa “Statistical Package for Social Sciences” (SPSS), versão 23.0 (IBM Corporation, Armonk, NY, EUA) foi utilizado nas análises (p<0,05). Resultado Encontrou-se uma prevalência de TD de 33/73 (45,2%) entre os PD. A fratura predominante foi a do tipo coronária, com uma frequência de 26/33 (78,8%). A maioria dos pacientes tinha acima de 20 anos, com uma frequência de 63/73 (86,3%), significativamente maior do que as frequências das outras categorias (p < 0,008). Os pacientes da amostra apresentavam doenças variadas, sendo as mais prevalentes as das categorias mental, com frequência de 22/73 (30,1%), múltipla com 19/73 (26%), e sistêmica com 14/73 (19,2%). Conclusão Foi encontrada uma alta prevalência de TD em PD, sendo a maioria dos casos relacionados a doenças mentais e múltiplas. Futuras pesquisas são necessárias para avaliar a prevalência de TD nesse grupo de pacientes em todo o Distrito Federal.Introduction In Brazil, dental trauma (DT) is considered a public health problem.

Inflammation markers in healthy and periodontitis patients: a preliminary data screening

Advances in diagnostic research are moving towards methods whereby the periodontal risk can be identified and quantified by objective measures using biomarkers. Patients with periodontitis may have elevated circulating levels of specific inflammatory markers that can be correlated to the severity of the disease. The purpose of this study was to evaluate whether differences in the serum levels of inflammatory biomarkers are differentially expressed in healthy and periodontitis patients. Twenty-five patients (8 healthy patients and 17 chronic periodontitis patients) were enrolled in the study. A 15 mL blood sample was used for identification of the inflammatory markers, with a human inflammatory flow cytometry multiplex assay. Among 24 assessed cytokines, only 3 (RANTES, MIG and Eotaxin) were statistically different between groups (p<0.05). In conclusion, some of the selected markers of inflammation are differentially expressed in healthy and periodontitis patients. Cytokine profile analysis may be further explored to distinguish the periodontitis patients from the ones free of disease and also to be used as a measure of risk. The present data, however, are limited and larger sample size studies are required to validate the findings of the specific biomarkers.Avanços no diagnóstico da doença periodontal levam a métodos nos quais o risco e atividade da doença periodontal podem ser identificados e quantificados por biomarcadores. Pacientes com periodontite podem apresentar elevados níveis circulatórios de marcadores inflamatórios específicos que podem ser correlacionados com a severidade da doença. Portanto, o objetivo desse estudo foi avaliar as diferenças nos níveis séricos de biomarcadores inflamatórios em pacientes saudáveis e com doença periodontal. Foram incluídos no estudo 25 pacientes (8 saudáveis e 17 com periodontite crônica). Uma amostra de 15 mL de sangue foi obtida para identificar os marcadores inflamatórios simultaneamente utilizando Array de proteínas através de citometria de fluxo. De 24 citocinas inflamatórias analisadas, apenas 3 (RANTES, MIG e Eotaxina) apresentaram diferenças estatisticamente significantes (p<0,05) entre os dois grupos. Conclui-se que alguns marcadores inflamatórios selecionados apresentam diferença de concentração em pacientes com periodontite e saudáveis. A análise do perfil de citocinas pode ser utilizada tanto para distinguir pacientes periodontais de pacientes saudáveis, como para medir o risco à doença. Contudo, mais estudos com número maior de amostras são necessários para validar os achados sobre os biomarcadores específicos.FAPESPCNP

Salivary biomarkers of periodontal patients with type 2 diabetes mellitus

A associação entre o diabetes e a periodontite produz uma descarga de proteínas inflamatórias que pode ser refletida na saliva. Com base nisso, o objetivo desse estudo foi mensurar as concentrações salivares de interleucina-6 (IL-6), metaloproteinase da matriz-8 (MMP-8) e osteoprotegerina (OPG) em pacientes com periodontite crônica associada ou não ao diabetes mellitus tipo 2. Um total de 90 indivíduos foi dividido em quatro grupos: saudáveis (Controle, n=22), pacientes com doença periodontal (DP, n=24), apenas com diabetes mellitus (DM, n=20) e com doença periodontal e diabetes mellitus (DP+DM, n=24). Dados clínicos e metabólicos foram registrados. Amostras de saliva não-estimulada foram analisadas pelo ensaio imunoenzimático (ELISA). Diferenças estatisticamente significantes foram detectadas entre os grupos para todos marcadores (p=7 (profundidade de sondagem>=7mm) correlacionou-se positivamente com as concentrações de MMP-8 (r=0,46; p=7 (pocket depth>=7mm) correlated positively with MMP-8 concentrations (r=0.46; p<0.05), also HbA1c levels correlated positively with IL-6 concentrations (r=0.54; p<0.000). Conclusion: Saliva is an adequate substrate for inflammatory biomarkers identification in periodontal patients. IL-6 is a candidate biomarker for periodontitis and periodontitis associated to diabetes in the saliva

Diagnostic biomarkers related to periodontal disease activity in diabetics

O objetivo geral deste estudo foi monitorar a atividade da doença periodontal e sugerir potenciais biomarcadores salivares relacionados a esta atividade em pacientes com periodontite crônica associada ou não Diabetes mellitus tipo 2, a partir da avaliação do perfil da expressão gênica de sítios periodontais progressivos e de proteínas inflamatórias salivares. Foram incluídos 56 pacientes, sendo 21 com periodontite crônica (DP), 20 com periodontite crônica associada ao Diabetes mellitus tipo 2 (DP+DM) e 15 periodontal e sistemicamente saudáveis (controle). Foi realizado exame radiográfico antes e dois meses após a terapia periodontal básica, e posteriormente foi feita a subtração radiográfica a partir dos pares das radiografias. As medidas das áreas com perda de densidade foram registradas. Coleta de saliva não estimulada, verificação da hemoglobina glicada (HbA1c) e exame clínico periodontal profundidade de sondagem (PS), nível clínico de inserção relativo (NCIR), sangramento à sondagem (SS) e índice de placa (IP) também foram realizados antes e dois meses após a terapia periodontal básica. Os sítios periodontais com perda de inserção progressiva 1 mm na reavaliação foram considerados ativos de acordo com uma adaptação do método de tolerância. Biópsias de tecido gengival de sítios ativos e inativos com parâmetros clínicos semelhantes foram analisadas com real time PCR Array para análise do perfil de expressão gênica da resposta imune-inflamatória. As amostras de saliva foram submetidas ao imunoensaio Multiplex Cytokine Profiling para análise de expressão de proteínas. No grupo DP, 9% dos sítios foram classificados como ativos e no grupo DP+DM, 12% (p > 0,05). A média de perda de inserção clínica foi maior no grupo DP+DM (1,34 mm) em relação ao grupo DP (1,21 mm) (p 0,05). Concluindo, este estudo foi capaz de monitorar a atividade da doença periodontal em pacientes com e sem diabetes após a terapia periodontal básica; foi possível identificar genes diferencialmente expressos em sítios ativos de ambos os grupos, que podem ser úteis na indicação de potenciais biomarcadores para diagnóstico da doença periodontal na fase ativa; as proteínas salivares analisadas mostram uma tendência em diferenciar o padrão de saúde e de doença, podendo ser futuramente utilizadas como potenciais biomarcadores de periodontite associada ou não ao diabetes.The overall aim of this study was to monitor the periodontal disease activity and suggest potential salivary biomarkers related to this activity in chronic periodontitis patients with or without type 2 Diabetes mellitus (DM), based on the evaluation of gene expression profile of progressive periodontal sites and salivary inflammatory proteins. Fifty-six patients were enrolled, 21 with chronic periodontitis (PD group), 20 with chronic periodontitis and DM (PD+DM group) and 15 periodontal- and systemically healthy (control). Radiographs were taken before and two months after non-surgical periodontal therapy, and radiographic subtraction was performed from pairs of these radiographs. Measurements of the areas with density loss were recorded. Unstimulated saliva collection, glycated hemoglobin (HbA1c) measurement and periodontal examination probing pocket depth (PPD), relative clinical attachment level (rCAL), bleeding on probing (BOP) and plaque index (PI) were also conducted before and two months after non-surgical periodontal therapy. The periodontal sites with progressive attachment loss 1 mm at the recall visit were considered active sites according to the adapted method of tolerance. Gingival biopsies of active and non-active sites with similar clinical parameters were harvested for gene expression analysis of the immune-inflammatory response with Real Time PCR Array. Saliva samples were analyzed by Multiplex Cytokine Profiling Immunoassay for analysis of protein expression profile. In PD group, 9% of the sites were classified as active and in PD+DM group, 12% (p > 0.05). The clinical attachment loss mean was higher in the PD+DM group (1.34±0.23 mm) compared to the PD group (1.21±0.16 mm) (p 0.05). In conclusion, this study was able to monitor the periodontal disease activity in periodontal patients with or without diabetes after the non-surgical periodontal therapy; it was possible to identify genes differentially expressed in active sites from both groups, which may be considered useful in indicating potential biomarkers for the diagnosis of active periodontal disease; salivary proteins show a trend in distinguishing the standard of health and disease and may be used in the future as potential biomarkers of periodontitis with or without diabetes
