Abstract
Background
The individual knowledge of the effects of tobacco usage on health plays an important role in its uptake. Tobacco consumption usually starts during adolescence, and lack of knowledge about the oral problems of tobacco usage probably plays a role in it.
Aim
To determine the knowledge of adolescents about the effect of tobacco usage on oral health.
Methods
A cross-sectional study was conducted among 1,465 adolescents aged 12 to 20 years who attended senior secondary schools in a major city in Nigeria. Data were obtained through a semistructured questionnaire. Data obtained were analyzed with SPSS.
Results
The mean age of respondents was 15.2 (±1.4) years. Only 40 (2.7%) of them used tobacco at the time of study and 992 (67.7%) said that tobacco usage has effect(s) on oral health. The main effects mentioned were mouth odor: 338 (34.1%); teeth discoloration: 297 (29.9%); tooth decay: 138 (13.9%); damage to teeth: 72 (7.3%); lip discoloration: 39 (3.9%); and oral cancer: 11 (1.1%). It was found that female respondents (72.1%, odds ratio = 1.4, confidence interval = 1.1–1.7, p = .005); those aged 12 to 15 years (73.6%, odds ratio = 2.0, confidence interval = 1.6–2.5, p < .001); and children of skilled workers (73.4%, odds ratio = 1.9, confidence interval = 1.2–3.0, p = .008) were more likely to mention that tobacco has adverse effect(s) on oral health.
Conclusion
Although two thirds of the students knew that tobacco usage has effects on oral health, there were gross inadequacies in the knowledge and misconceptions about those effects.
