RESUMEN
Background: In our study, we compare the power toothbrush with the manual toothbrush and the results showed were contradictory. Where few studies have reported that power toothbrushes are superior, other studies showed that both are equally efficacious in removing dental plaque. Aims: The present study was conducted to evaluate and compare the efficacy of manual toothbrush with an electric toothbrush in reducing dental plaque and gingivitis. Materials and Methods: The study included a total of 56 subjects which were randomly divided into two groups of 28 subjects each. At week 1, disclosing agent (two-tone solution) was used to detect plaque, and Loe and Silness Gingival Index were used to assess gingival scores. Oral hygiene instructions and brushing were also reinforced. A similar protocol was repeated at one, two, and six weeks. The collected data were subjected to statistical evaluation. Results: At two weeks, the plaque score for manual and power toothbrushes were 60.253 ± 20.672 and 44.031 ± 16.484, respectively, and this difference was statistically significant with P = 0.0020. At six weeks, plaque scores for manual and power toothbrushes were 43.784 ± 22.647 and 20.489 ± 10.336, respectively, and were statistically significant (P < 0.0001). Conclusion: The present study concludes that powered toothbrush has added advantages of improved oral hygiene compared to manual toothbrush concerning plaque reduction. This can be attributed to predefined power and force which can effectively remove plaque, calculus, and improved gingival health.
RESUMEN
The decreasing effectiveness of antimicrobial agents is a global public health threat, yet risk factors for community-acquired antimicrobial resistance (CA-AMR) in low-income settings have not been clearly elucidated. Our aim was to identify risk factors for CA-AMR with extended-spectrum ß-lactamase (ESBL)-producing organisms among urban-dwelling women in India. We collected microbiological and survey data in an observational study of primigravidae women in a public hospital in Hyderabad, India. We analyzed the data using multivariate logistic and linear regression and found that 7% of 1,836 women had bacteriuria; 48% of isolates were ESBL-producing organisms. Women in the bottom 50th percentile of income distribution were more likely to have bacteriuria (adjusted odds ratio 1.44, 95% CI 0.99-2.10) and significantly more likely to have bacteriuria with ESBL-producing organisms (adjusted odds ratio 2.04, 95% CI 1.17-3.54). Nonparametric analyses demonstrated a negative relationship between the prevalence of ESBL and income.
