Epidemiological Sampling Survery Of Recognition And Behavior Related To Dentine Hypersensitivity And Analysis Of Influen-cing Factorsamong Undergraduate Students And Associate Professors Of University

Objective To explore the related knowledge and behavior about dentine hypersensiti-vity of the students and the associate professors in a University, to provide the basis for university teachers and students’ prevention from DH and the healthcare.Methods Questionnaires was designed based on Oral Health Surveys of WHO and Consensus-Based Recommendations for the Diagnosis and Management of Dentin Hypersensitivity of Chinese Advisory Board on DH.300students and200teachers were investigated randomly in our study, which included in brushing habits, dietary habits, oral habits and medical behavior concerning with DH. Data were analyzed by using SPSS17.0statistical software which creates database and the statistical number rate, and chi-square test was used to test significance. Values of P is lower than0.05.Results In this study,493questionnaires were completely finished and used for further statistical analysis. Among these questionnaires, there were200teachers and293students.55.07%of students and64.0%of teachers were suffered from teeth sensitivity.Only6.5%of students and19.0%of teachers knew DH.2.39%of students and45.50%of teachers checked their dental health regularly. When the sensitivity happened, only14.63%of students and30.46%of teachers tried to help from the dentist. The primary reason in72.14%of students and82.02%of teachers was the lack of attention. There were many risk factors related to DH:12.63%of students and13.50%of teachers used hard toothbrush;18.77%of students and16.0%of teachers used undue pressure while brushing;89.08%of students’ brushing direction and82.5%of teachers’ were transverse;20.13%of students and6.0%of teachers drank carbonated more than once a week;54.63%of students and32.0%of teachers liked to eat acidic food;44.71%of students and41.0%of teachers liked hard food;13.31%of students and13.0%of teachers had nocturnal bruise;20.14%of students and24.0%of teachers had diurnal clenching;58.36%of students and57.5%of teachers had unilateral chewing, etc.The statistic data implied that the teachers did better than the students in terms of brushing their teeth after meals immediately, gargling after meals immediately, using dental floss, using toothpicks, insisting in brush vertical law, knowing dentine hypersensitivity, periodic oral health examination, seeking help from the dentist (P<0.05). The statistic data also implied that the students had higher rate than the teachers in terms of eating acidic food, drinking carbonated beverage (P<0.05). The statistic data implied that the male teachers had higher rate than the female in terms of using hard toothbrush, brushing with strong strokes, having diurnal clenching (P<0.05). The female teachers had higher rate than the male in terms of brushing their teeth after meals immediately, gargling after meals immediately, eating acidic food (P<0.05). The female students had higher rate than the male in eating acidic food and hard food (P<0.05). The male students had higher rate than the female in terms of brushing with strong strokes, using toothpicks, drinking carbonated more than once a week (P<0.05).Conclusion College students and teachers are lack of recognition and prevention from DH. Improving the education of oral knowledge is the effective method to reduce the incidence of DH.
