This prevalence should be considered high when compared to the following studies: Freire et al 27 performed in 26 capitals of Brazilian states and in the Federal District, where the prevalence of toothache was 17.8%; Jaiswal et al 28 , in Kollipara Mandal, Guntur district, Andhra Pradesh, India, whose prevalence of toothache was 28.3%; Rosa et al 29 , performed in 36 municipalities with up to 50,000 inhabitants in Rio Grande do Sul, where 29.8% reported having toothache in the last 6 months.
