Oral health knowledge and practices of clinical medical and dental students in a North- Eastern Nigerian University

Abstract

Objective: Medical and dental students as future health care professionals should be aware of adequate oral health care. Therefore, this study aimed to determine the knowledge and practices of oral health of clinical medical and dental students in a North-Eastern Nigerian University.Methods: Cross sectional study involving 150 students, comprising 107 medical and 43 dental students. They were interviewed on knowledge of oral health care, oral health practices and psychosocial impact of oral health using an interviewer-administered questionnaire. The students were further examined for dental caries and their oral hygiene status. The Student t-test was used to compare means while Chisquare test was used to test associations between categorical variables at p<0.05.Results: The mean ±SD age of the students was 24.5 , males constituted 61.3%. One hundred and twentysix (84.0%) students had good knowledge of oral health care. Forty-two (97.7%) of the dental students had good knowledge while 84 (78.5%) of the medical students had good knowledge (p=0.003). Twenty (46.5%) and 60(56.1%) of dental and medical students respectively had poor oral health practice (p=0.32). Mean ±SD psychosocial impact score was 1.26 ±2.06 and 1.53 ±2.34 for dental and medical students respectively (p=0.68). The prevalence of dental caries and poor oral hygiene was 15(34.9%) and 23(53.5%) for dental students. The corresponding value for medical students were 30(28.0%) and 51(47.6%).Conclusions: There was good knowledge of oral health care among these students. Dental students had better knowledge of oral health care than medical students. They also had better oral health care practices and lower psychosocial impact of oral health than medical students though not statistically significant. Overall, younger age group of students reported higher psychosocial impact of oral health care on daily activities than older ones.Keywords: Oral health, knowledge, behaviour, medical, dental, students, Nigeria
