Evaluation of the clinical effect of a probiotic mouthwash in the treatment of generalized marginal chronic gingivitis: randomized pilot study

Objective. to evaluate the clinical effect of a probiotic mouthwash in reducing generalized marginal chronic gingivitis using positive and negative control groups. methodology. four-week study conducted in San Luis Potosí, Mexico, from january to march 2017. participants were healthy, non-smokers with generalized marginal chronic gingivitis; age range 18-45 years. subjects were randomized and divided into three groups: group A: mouthwash based on 0.05 percent cetylpyridinium chloride (CPC) (positive control); group B: mouthwash based on probiotics (experimental); group C: placebo mouthwash (negative control). no oral hygiene practices or routines were modified; subjects were followed for 4 weeks. the primary outcome variable of interest was the Löe and Silness gingival index, and the secondary one, the Quigley Heinn plaque index modified by Turesky. results. of the 45 patients included, 19 (42.2 percent) were men and 26 (57.7 percent) women, mean age was 22.8±2.07. each group consisted of 15 subjects; all subjects completed the study. there was no statistically significant reduction in gingival inflammation when comparing the 3 treatment groups (p=0.540) with respect to the gingival index. A comparison was made before and after the treatment and in the 3 groups there was no reduction of the gingival inflammation. plaque reduction was not statistically significant when comparing the 3 groups (p=0.278). however, when doing intra-group comparison, it was found that the patients in group A had a reduction in plaque index (p<0.005), which was not observed in groups B (p=0.1103) and C (p=0.1508). conclusions. the use of a probiotic mouth mouthwash did not reduce gingival inflammation or the accumulation of dentobacterial plaque in a period of 4 weeks. there were no statistically significant differences between the study groups.

Perfil de presión uretral estático en la incontinencia urinaria de la mujer / Static urethral pressure profile in woman urinary incontinence

Se estudiaron en forma prospectiva 75 pacientes del sexo femenino con incontinencia urinaria identificada desde el punto de vista clínico. Se les realizó perfil de presión uretral estático sin micción y se encontró incontinencia de urgencia en 26, de esfuerzo en 25 y de tipo mixto en 24. No hubo diferencias en la previsión vesicalbasal. La longitud funcional de la uretra sí se afecta en el tipo de urgencia, y da como resultado diferencias con respecto a la de esfuerzo y mixta. Tanto la presión máxima de cierre como la uretral máxima disminuyen conforme progresa la edad de la mujer, sin guardar relación con el tipo de incontinencia. La presión máxima de cierre y uretral máxima en la incontinencia de urgencia produce diferencias a una p en relación con las de esfuerzo y mixta. La utilidad clínica del perfil de presión uretral es un aspecto controvertido. Los datos que se informan en este artículo indican que se tiene que revalorar su posición, pues podrían ser de gran ayuda para la valoración integral de la incontinencia urinaria de urgencia.
