This report describes the results of a survey on toothbrushing behavior and other health-related behaviors in young people. The survey instrument for this study gathered information about students' lifestyle and included a wide range of social, behavioral, and lifestyle variables. The survey encompassed 7,770 schoolchildren aged 14-15, from 131 secondary schools throughout England. The report is divided into four sections: an introduction which discusses survey methodology and the questionnaire; two sections that examine toothbrushing habits and toothbrushing motivation broken down by demographic variation, lifestyles, and dental health behavior; and a conclusion that summarizes the results and offers recommendations to improve toothbrushing. Results revealed a marked gender difference in brushing frequency, with females brushing more frequently than males. In general, better brushing practices were associated with higher self-esteem, Southerners, readers of reputable newspapers, and town dwellers. Students with higher self-esteem and more controlling attitudes seemed to brush for positive aesthetic reasons rather than for disease prevention. Those who brushed their teeth only once a day appeared more motivated by socially instrumental reasons, such as liking fresh breath. Some systematic differences in motivation for toothbrushing were observed, although contradictory tendencies appeared when attempts were made to generalize about particular reasons for toothbrushing.
