Abstract
Background: The number of international students enrolled in universities in Japan is increasing. To provide better oral care services for international students, we have to understand their oral environment and dental health behaviors. However, few studies have investigated the oral health status of international university students. The object of the present study was to clarify the current oral status of international university students. Methods: The subjects were students who visited the dental department at the University of Tokyo’s Health Services Center between April 2012 and March 2013. Our medical records were reviewed with regard to the following items: attributes (nationality, gender, and age); chief complaint (reason for visit); history of dental treatment; mean number of decayed (D), missing (M) or filled (F) teeth as a single (DMFT) index; degree of calculus deposition; gingival condition; and oral hygiene status. Results: The records of 554 university students (138 international and 416 non-international students) were analyzed; 88.4% of the 138 international students were from Asian countries (n = 122), of which 47.1% were from China and 10.9% from Korea, followed by North America (5.8%), Europe (4.3%), and Africa (1.5%). Although no significant differences were found regarding the history of dental treatment between international and non-international students (49.3% and 48.8%, respectively), international students had a significantly higher dental caries morbidity rate (60.1%) than non-international students (49.0%). The international students showed a significantly higher DMFT value compared with the non-international students: 5.0 and 4.0 per individual, respectively. Severe calculus deposition was observed in international students compared with non-international students (51.9% and 31.7%, respectively). Conclusions: The international university students had poorer oral health status than the non-international students, even though the result might include many uncertainties and possible biases.
