“…Other countries reported percentages above ours, as in Nicaragua, which was 51.6% [27], 52.1% in Nigeria [31], 64% in Poland [28], 69% in Jordan [29], 72% in Spain [12], 88% in Thailand [30], close to 100% in Brazil [33], or in Sweden, where data have varied between 84% and 94% in several age groups [32]. Similarly, for various European countries, the USA, and Canada, reports ranged between 16–80% in boys and 26%–89% in girls [34,35], or 47% in socially disadvantaged groups in New Zealand [36]. In Mexico, Villalobos et al [39] observed a 56.3% prevalence of daily tooth brushing in schoolchildren from northwest Mexico, while in southeast Mexico community figures vary from 72% [40] to 82% [37,38] – percentages far higher than that observed in the present study.…”
