- Abstract
Purpose: This study analyzed associations of cumulative learning, demographic characteristics, fluoride content, and toothbrush head size with the amount of toothpaste used by dental students. Methods: Students in the third and fifth year of dental school were recruited. Each participant was asked to dispense three toothpastes (pediatric, regular fluoride, and high fluoride) on five toothbrushes (rotation-oscillation, sonic, manual pediatric, and two manual adult toothbrushes). The length and weight of the toothpaste dispensed were recorded. The data were evaluated by nonparametric correlation analysis (P < 0.05). Results: Eighty-one students (third year = 42; fifth year = 39; mean age: 26.2 ± 5.3 years) participated in the study. More toothpaste was dispensed by third-year students than by fifth-year students (weight: P = 0.014; length: P = 0.037). Men dispensed more toothpaste than did women (weight: P < 0.001; length: P = 0.042). Participants with higher educational attainment dispensed less toothpaste (weight: P < 0.001; length: P < 0.001). The type of toothbrush was associated with the weight of toothpaste dispensed (P < 0.001). Toothbrush head size was inversely associated with the length of toothpaste dispensed (P < 0.001). Conclusion: The amount of toothpaste used by dental students was associated with cumulative learning, educational attainment, sex, and toothbrush head size but not with the fluoride content of the toothpaste.
