ABSTRACT

a enfermedad periodontal destructiva afecta los tejidos de soporte del diente, teniendo como consecuencia final la pérdida del mismo; por lo cual la investigación se dirige hacia medidas objetivas de identificación de riesgo como lo son los biomarcadores de destrucción. Debido a que los estudios realizados con biomarcadores presentes en el fluido gingival crevicular (FGC) han reportado resultados promisorios, es factible asociar marcadores de degradación tisular con la progresión de la enfermedad periodontal. El objetivo del presente estudio es determinar el efecto del tratamiento periodontal no quirúrgico, sobre los niveles de ICTP en el FGC de pacientes con periodontitis crónica. Materiales y métodos: En muestras de FGC (pre y postratamiento), tanto de sitios activos como de inactivos determinados según el método de tolerancia, se midieron los niveles de ICTP utilizando el ICTP EIA. Uni Q, los resultados se analizaron usando el programa Stata 7.0 y el student-test para las muestras no paramétricas. Resultados: Los niveles de ICTP disminuyeron significativamente después de realizar el tratamiento periodontal no quirúrgico (p= 0,0001). Conclusiones: De acuerdo con los resultados obtenidos, la ICTP puede ser un buen marcador para monitorear los efectos del tratamiento periodontal no quirúrgico.


he destructive periodontal disease affects the tissues supporting the teeth, with the final result in the loss of it; so the research is directed towards identifying objective measures of risk such as biomarkers of destruction. Because studies of biomarkers present in the gingival crevicular fluid (FGC) have reported promising results, it is posible associated markers of tissue degradation with the progression of periodontal disease. The aim of this study is to determine the effect of nonsurgical periodontal treatment on the levels of pyridinoline in the FGC patients with chronic periodontitis. Materials and Methods: FGC samples (before and after treatment), both active and inactive sites determined by the method of tolerance, ICTP levels were measured using the ICTP EIA. Uni Q, the results were analyzed using Stata 7.0 program and the student-test for nonparametric samples Results: ICTP levels decreased significantly after performing non-surgical periodontal treatment (p = 0.0001). Conclusions: According to the results, the ICTP may be a good marker to monitor the effects of nonsurgical periodontal treatment.

ABSTRACT

O hiperparatiroidismo secundário (HPTS), observado nos doentes urémicos, apesar de se instalar desde estadios precoces da insuficiência renal,apresenta manifestações clínicas pouco específicas e frequentemente tardias. Para além da promissora técnica de avaliação da arquitectura trabecularóssea por tomografia quantitativa microcomputorizada os métodos imagiológicos são de escassa utilidade no diagnóstico das alterações ósseasassociadas ao HPTS. Ao longo dos últimos anos foram avaliados diversos marcadores bioquímicos da remodelação óssea e a respectiva utilidade nodiagnóstico não invasivo da osteodistrofia renal. Finalmente, é ainda discutido o eventual papel de factores locais (citoquinas e factores de crescimento) na modulação da remodelação óssea.


Secondary hyperparathyroidism represents one extreme of the spectrum of the bone and endocrine changes observed in uraemic patients, and may develop since early stages of renal failure. The clinical symptoms and signs are non-specific and the contribution of image evaluation in the diagnosis of secondary hyperparathyroidism is, frequently, misleading. In this review, in addition to the classic modulators of bone remodeling, like parathyroid hormone (and PTHfragments), calcitriol and calcitonin, the role of others local factors involved in osteoblast and osteoclast activation, like cytokines and growth factors, is alsodiscussed.
