Comparison of effectiveness of abrasive and enzymatic action of whitening toothpastes in removal of extrinsic stains - a clinical trial.

OBJECTIVE: To compare the effectiveness of abrasive component (perlite/calcium carbonate) and enzymatic component (papain and bromelain) of whitening toothpaste in removal of extrinsic stains. METHODS: This study is a randomized, triple blind and parallel group study in which 90 subjects aged 18-40 years were included. At baseline, stains scores were assessed by Macpherson's modification of Lobene Stain Index and subjects were randomly assigned to two groups with 45 subjects in each. Group 1 used whitening toothpaste with enzymatic action and group 2 with abrasive action. After 1 month, stain scores were assessed for the effectiveness of the two toothpastes and 2 months later to check the stain prevention efficacy. Wilcoxson's test was used to compare between baseline 1 and 2 months stain scores, and Mann-Witney U-test was applied for intragroup comparison. RESULTS: The mean baseline total stain score for the subjects allocated to the enzymatic toothpaste was 37.24 ± 2.11 which reduced to 30.77 ± 2.48 in 1 month, and for the abrasive paste, total stain reduced from 35.08 ± 2.96 to 32.89 ± 1.95. The reductions in total stain scores with both the pastes were significant compared with baseline stain scores (at 1 month Group 1, P = 0.0233 and Group 2, P = 0.0324; at 2 months, Group 1 P = 0.0356). Both the toothpastes proved to be equally good in removal of extrinsic stains; however, the enzymatic paste showed better results as compared to abrasive toothpaste. CONCLUSION: Whitening toothpaste with abrasive action and enzymatic action are equally effective in removal of extrinsic stains; however, whitening toothpaste with abrasive action needs to be used with caution.

Association of socio-economic status and dietary habits with early childhood caries among 3- to 5-year-old children of Belgaum city.

AIM: To ascertain if there were any association of socio-demographic factors and dietary habits with early childhood caries (ECC). METHODS: A cross-sectional study was conducted on 1,250 children 3-5 years of age. A self-designed validated questionnaire was prepared comprising two parts, one pertaining to socio-demographic data and the other related to a 3-day diet diary. Socio-economic stratification was based on Kuppuswamy's classification. Diet history was obtained via a 3-day diet diary completed by the parents. A calibrated examiner conducted the oral examinations of the preschool children. Dental caries was assessed by using WHO criteria. Chi-square test and logistic regressions described the strength of the associations. RESULTS: The prevalence rate of ECC was 63.17 %. Significant associations were obtained between ECC and age of the child, number of siblings in the family, mother's education, sucrose exposure in between meals, sucrose exposure at meals, total frequency of sucrose exposure, and total sweet score. However, non-significant association of ECC was observed with socio-economic status. CONCLUSION: Many of the socio-demographic and dietary factors were significantly associated with ECC. It would be appropriate to plan health education strategies for parents and care takers by inculcating socio-demographic factors with emphasis on reduced sucrose intake. ECC should be regarded as a serious public health problem.
