ABSTRACT

Objetivo: Comparar las concentraciones de proteínas carboniladas y capacidad antioxidante total (CAT) en fluido crevicular gingival (FCG) de pacientes con recién diagnóstico de diabetes mellitus tipo 2 (DM2) con periodontitis crónica (PC), sujetos con PC y sujetos con gingivitis (G). Material y métodos: Estudio transversal en sujetos de ambos sexos (35-55 años). Se formaron tres grupos: DM2+PC, PC y G. Se incluyeron sujetos con ≤ 1.6 años de DM2 con PC. Se evaluaron parámetros clínicos y periodontales. Los marcadores de estrés oxidativo (OxS) se determinaron por colorimetría y se cuantificaron por espectrofotometría. Se utilizó ANOVA/Kruskal-Wallis para observar diferencias entre los grupos y se analizaron las correlaciones con Pearson/Spearman. Resultados: El grupo DM2 + PC mostró un incremento significativo en la edad, índice de masa corporal y glucosa en comparación con los grupos PC y G. La profundidad de la bolsa (PD), pérdida de inserción, sangrado e índice gingival fueron mayores en el grupo DM2 + PC versus grupos PC y G (p < 0.001). No se encontró diferencia entre los grupos en CAT. El grupo DM2 + PC mostró mayor concentración de proteínas carboniladas versus grupo G (p = 0.03). PD correlacionó directamente con LDL en el grupo DM2 + PC (p = 0.04). Conclusión: Las proteínas carboniladas en el grupo DM2 + PC presentaron una diferencia significativa, indicando el daño oxidativo sinérgico de ambas patologías. La concentración de CAT tiende a elevarse en el grupo DM2 + PC, probablemente como un mecanismo compensatorio en busca del restablecimiento de homeostasis (AU)


Objective: To compare the concentrations of carbonylated proteins and total antioxidant capacity (TAC) in gingival crevicular fluid (GCF) of patients with newly diagnosed type 2 diabetes mellitus (DM2) with chronic periodontitis (CP), subjects with CP and subjects with gingivitis (G). Material and methods: Cross-sectional study in subjects of both sexes (35-55 years). Three groups were formed: DM2 + CP, CP and G. Subjects with ≤ 1.6 years of DM2 with CP were included. Clinical and periodontal parameters were evaluated. OxS markers were determined by colorimetry and quantified by spectrophotometry. ANOVA/Kruskal Wallis was used to observe differences between the groups and the correlations were analyzed with Pearson/Spearman tests. Results: The DM2 + CP group showed a significant increase in age, body mass index and glucose in comparison with groups CP and G. The depth of the pocket (DP), insertion loss, bleeding and gingival index were higher in the group DM2 + CP versus groups CP and G (p < 0.001). No difference was found between the groups in TAC. The DM2 + CP group showed a higher concentration of carbonylated proteins versus group G (p = 0.03). DP correlated directly with LDL in the DM2 + CP group (p = 0.04). Conclusion: The carbonylated proteins in the DM2 + CP group showed a significant difference, indicating the synergistic oxidative damage of both pathologies. The concentration of TAC tends to rise in the DM2 + CP group, probably as a compensatory mechanism in search of the restoration of homeostasis (AU)
