Frequency of tooth brushing and associated factors among adolescents in western Norway

Abstract

Dental caries is the most prevalent disease in Norway and worldwide, and daily tooth brushing with fluoridated toothpaste is the main preventative measure when diets contain sugary foods. Tooth brushing is an important public health indicator, as the frequency of brushing also has been positively associated with good health in general. In Norway, brushing twice a day is the official recommendation. Our aim was to assess the frequency of tooth brushing among pupils in secondary school in two counties in western Norway, and to identify factors associated with brushing more than once a day. All 59 borough administrations in the two counties were invited to participate in the Ungdata survey in 2015-16; 26 agreed. In total 8,725 pupils filled in the electronic questionnaire (82%). Some 69% brushed their teeth more frequently than once a day, specifically 76% of whom were girls and 63% were boys (adjusted odds ratio=2.0). Of the boys, 6.5% did not brush daily. In 8-10th school grade 71% brushed more than once a day, compared to 65% in 11-13th grade. Out of 28 a priori selected factors, eight were independently associated with frequency of tooth brushing. Besides gender, the strongest associations observed were for frequency of brisk physical exercise, parents being informed about their adolescent’s whereabouts, and satisfaction with one’s own health.

Dental caries and associated factors among adolescents aged 12 to 15 in Jiangxi Province, China

“…In addition, eating habits, social status, and sociodemographic factors also contribute to the development of caries. [4][5][6][7][8] Although dental caries can be prevented and treated, dental decay is a cumulative process that can eventually cause tooth loss if intervention and treatment do not occur in the early stages. 9 In addition, dental caries may affect adolescents' nutrition, growth, development, oral health, general health, and quality of life.…”

Dental caries at enamel and dentine level among European adolescents – a systematic review and meta-analysis

“…As a consequence, adolescent behaviour patterns differ from those in childhood and adulthood. Risk of caries in this phase of life is higher due to environmental factors such as a changing, sometimes poor, diet [5]; a lowering of oral hygiene standards [6,7]; and a new independence for seeking, or avoiding, dental care [8]. The 12-15-year-old age group also faces a greater caries risk [9] due to newly erupted permanent canines, premolars, and second molars; 76 new tooth surfaces become exposed during this period.…”

Investigating hope in oral health promotion for adolescents: an exploratory study based on observations at the dental clinic

“…It can have adverse effects on a child's quality of life, academic performance, and overall cognitive and psychosocial development ( 2 ). Moreover, the risk of dental caries tends to increase as individuals reach the age of 12 ( 1 ) due to diet ( 3 ), potential declines in oral hygiene practices ( 4 , 5 ), and independence in seeking or avoiding dental care ( 6 ). Despite progress being made in children's oral health, data from Norway indicates that two-thirds of 18-year-olds have experienced dental caries ( 7 ), and dental erosion affects 38% of 16-year-olds ( 8 ).…”
