Understanding/Promoting Oral Health of Indonesian Domestic Helpers in Hong Kong

Information is lacking on the oral health of Indonesian domestic helpers (IDHs) in Hong Kong. This community faces difficulties in accessing dental services. Objectives: to profile the oral health status and related behaviours of IDHs in Hong Kong and provide dental services to them. Methods: A random sample of 163 IDHs (aged 20-59) was recruited. A questionnaire collected information on their socio-demographic profile and oral health behaviours (knowledge, attitudes, practice and self-efficacy). Tooth status, periodontal health and oral hygiene status were assessed. An oral health talk and basic dental treatments were delivered, including scaling, topical fluoride application and atraumatic restorative treatment. Results: Over 90% of IDHs were affected by dental caries. The mean (SD) DMFT was 5.04 (3.79). Periodontal pockets existed in 45% participants. Despite participants' sound knowledge, attitudes and self-efficacy on oral health, many held a fatalistic view (perceiving tooth loss as a natural process of ageing). Despite the reasonable diet and toothbrushing habits, flossing was rarely practiced, although some started flossing after settling in Hong Kong. Socializing with others and good living condition were associated with favourable oral health behaviours and better oral health. Our outreach dental services were rated, anonymously, as useful/effective. Conclusions: Oral health of IDHs in Hong Kong is unsatisfactory. Oral health education is needed and should focus on encouraging flossing and expelling fatalistic conceptions on oral health. Participation in social activities and improvement in living condition are conducive to IDHs' oral health. Outreach services are practical to deliver basic dental cares to this community.
