Objective: To assess knowledge about dental erosion and determine frequency of consumption of carbonated drinks among a group of Nigerian medical and dental undergraduate students.
Methods: A self administered questionnaire was used to collect information on demography, knowledge about dental erosion, and consumption of carbonated drinks from students. Students were chosen using stratified sampling method. Each level of study was taken as a stratum and students were then chosen from each stratum by systematic sampling.
Results: A total of 387 questionnaires were returned. Less than a quarter (22.7%) of the respondents correctly describes what they understood to be dental erosion while 60.5% incorrectly answered that ‘sugar is involved in the aetiology of erosion of teeth’. Dental students significantly had better knowledge of acid erosion than the medical students (p < 0.05). Many (42.4%) of the respondents drank carbonated drinks 2-4 times a week and frequency of consumption was not significantly affected by knowledge of dental erosion (p > 0.05).
Conclusion: Knowledge of acid erosion was found to be low especially among the medical students indicating a need to include teaching about dental erosion in the general medical school curriculum. Consumption of carbonated drinks was common amongst the surveyed students.
Keywords: Knowledge, Dental erosion, Frequency, Carbonated drinks, Consumption, Students
Résumé
Pour évaluer les connaissances par rapport a l’érosion dentaire et déterminer la fréquence de la consommation des boissons gazéifiées parmi les étudiants Nigérians en médecine et soins dentaires. Un questionnaire librement administré, était utilisé pour collecter les données démographiques, connaissance, érosion dentaire, et consommation des boissons gazéifiées parmi les étudiants. Les étudiants étaient choisis par la méthode stratifiée Chaque niveau d’étude était prise comme un strata et les étudiants étaient ainsi choisit de chaque strata de façon systématique. Au total 387 questionnaires étaient retournés. Moins du quart (22.7%) des participants décrivaient correctement ce qu’ils comprennent par érosion dentaire alors que 60.5% répondaient
fausses que le sucre est impliqué dans l’étiologie de l’érosion des dents’. Les étudiants dentistes avaient significativement une meilleure connaissance de l’érosion par l’acide que les étudiants en médecine (p < 0.05). Plusieurs (42.4%) des participants buvaient les boissons gazéifiées 2-4 fois par semaine et and la fréquence de consommation n’affectait pas significativement par la connaissance de l’érosion dentaire (p > 0.05). En conclusion, la connaissance de l’érosion par l’acide était faible spécialement parmi les étudiants en médicine indiquant le besoin d’inclure les enseignements sur l’érosion dentaire dans leur curriculum. La consommation des boissons gazéifiées était commune parmi ces étudiants
