Dental health of Vietnamese Boat People on Pulau Bidong, Malaysia.

The influx of refugees from Vietnam to the industrialized countries has attracted a certain interest to studies describing the oral health status of these population groups. The present study comprises 361 refugees arriving in Malaysia from Vietnam and collected immediately at the refugee camp on Pulau Bidong. Dental caries, calculus, gingival bleeding and loss of periodontal attachment were recorded. Mean dmft increased from 1.3 for 0-2-yr-olds to 7.4 for 3-5-yr-olds. For 6-9-yr-olds mean DMFT was 2.4 while it ranged between 8.5 and 10.10 for the older age groups. The frequency of secondary lesions was high for all age groups. Calculus increased consistently with age, while gingival bleeding was common even in the youngest age group. Loss of periodontal attachment greater than or equal to 6 mm was rare in all age groups except the oldest (45 yr or older). A strategy for oral health care for these population groups is discussed.
