Factors associated with changes in self-reported dentifrice consumption in a brazilian group from 1996 and 2009

Abstract

The aim of the study was to determine factors associated with changes in self-reported dentifrice consumption in an urban population group over 13 years. This study evaluated two surveys of 671 and 688 households sampled in the urban area of a city from Southern Brazil in 1996 and 2009, respectively. The mother of the family was asked to answer a structured questionnaire about demographics, socioeconomic and behavioral variables. The primary outcome was obtained by questioning "how long does a dentifrice tube last in your house?" The cut-off point of duration was less than 1 month. It was used to determine high consumption of dentifrice (HCD). Associations between HCD and independent variables were evaluated by multivariable Poisson regression. There was a significant decrease of 20% (81.2% to 61.2%) in the prevalence of HCD between 1996 and 2009, resulting in a crude annual decrease of 1.54%. Mother's age, family income, dental assistance, mother's brushing frequency and number of household members that use a toothbrush were significantly associated with HCD independent from the year of survey. The prevalence ratio (PR) of HCD for the year of survey was 0.75, indicating an overall decrease of 25% in the probability of HCD from 1996 to 2009. Probabilities of HCD also decreased over the 13 years among the strata of education, number of household members and reason for choice of dentifrice. It may be concluded that the factors associated with the observed decrease were higher educational levels, larger number of household members and reasons for choosing a dentifrice related to preventive/therapeutic effects.

Epidemiology of periodontal diseases in adults from Latin America

“…Contradictory findings on the consumption of oral hygiene products were observed upon comparison of the data from two surveys, conducted 13 years apart in an adult Southern American population . Whereas dentifrice consumption in this population was high at both time‐points, the percentage of households using more than one tube of dentifrice per month decreased from 81.2% in 1996 to 61.2% in 2009.…”

Factors associated with self‐reported use of mouthwashes in southern Brazil in 1996 and 2009

“…This lack of studies demonstrates that this field has been overlooked in systematic research approaches. This fact is worrisome, as changes in the use of oral hygiene products have been associated with changes in health status of both individuals and populations , demonstrating their importance in the oral health context.…”

“…In this respect, in an analysis on the consumption of toothpaste, Colussi et al . observed that mother's age and family income were associated with greater use of this oral hygiene product.…”
