This study was conducted to test the null hypothesis that no difference exists in the oral hygiene knowledge and practices of university students in different courses when they have equal opportunity to access health-promotive dental care.
The study was conducted using 120 students each from the medical and engineering colleges at the University of Manipal Academy of Higher Education who had easy access to the dental college within the campus which provides health-promotive dental care to all its patients. A self-administered structured questionnaire consisting of questions on demographic data, oral hygiene knowledge and practices, and dental service utilization patterns was distributed among the students. The data collected was analyzed using SPSS 10 version.
Statistically significant differences were found between the two groups with respect to the knowledge of fluoridated toothpastes, frequency of toothbrush renewal, use of dental floss, and a tongue cleaner (p < 0.001). The groups were similar in all other practices including the utilization of dental services. There were no significant differences between the self-reported oral hygiene knowledge and practices among medical and engineering university students, but the knowledge levels of the students were considerably lower than expected.
本研究旨在检验零假设，即在有平等机会获得促进健康的牙科护理时，不同课程的大学生在口腔卫生知识和实践方面不存在差异。
该研究选取了马尼帕尔高等教育学院医学院和工程学院各120名学生，这些学生可方便地前往校园内为所有患者提供促进健康的牙科护理的牙科学院。向学生发放了一份自行填写的结构化问卷，内容包括人口统计学数据、口腔卫生知识和实践以及牙科服务利用模式等问题。收集到的数据使用SPSS 10版本进行分析。
两组在含氟牙膏知识、牙刷更换频率、牙线使用和舌刷使用方面存在统计学上的显著差异（p < 0.001）。在包括牙科服务利用在内的所有其他实践方面，两组情况相似。医学和工程专业大学生自我报告的口腔卫生知识和实践之间没有显著差异，但学生的知识水平远低于预期。
