Objective: To determine the in vitro antibacterial effect of different concentrations of the ethanol extract of Plantago major (plantain) on Porphyromonas gingivalis and Fusobacterium nucleatum. Material and Methods: Bacterial susceptibility tests were used in conjunction with the agar diffusion test and the minimum inhibitory concentration (MIC) test using the broth macrodilution technique. Results: Different concentrations of ethanol extract (25%, 50%, 75% and 100%) dissolved in 70% ethanol were used, with a positive control (0.12% chlorhexidine + 0.05% cetyl-pyridinium chloride) and a negative control (70% alcohol). The extracts at 75% and 100% showed inhibition halos against both strains studied. With 0.12% chlorhexidine + 0.05% cetyl-pyridinium chloride, inhibition halos averaged 14.9 mm, in contrast to 70° alcohol, where no bacterial inhibition was observed. The MIC was 50% for bo...

Objective: To determine the C-reactive protein level according to the periodontal state, age and trimester of pregnancy in pregnant women who attend the Centro de Salud Magna Vallejo, Cajamarca, Peru. Materials and methods: An observational, descriptive and cross-sectional study conducted in a sample of 60 pregnant women divided into three groups: those who were periodontally healthy, those with gingivitis and those with periodontitis. The Russell Index was used to determine the periodontal status. The value of the C-reactive protein level was taken from each patient’s medical record. Results: An elevated C-reactive protein level was found in 66.70 % of the pregnant women with gingivitis, 100 % of the pregnant women with periodontitis and 84.60 % of the adult pregnant women. Conclusions: C-reactive protein levels tend to rise in patients with periodontal disease and increase in adult ...
