Dental caries prevalence and dental health behaviour in HIV infected children

Objectives . To determine dental caries prevalence in a group of HIV positive children and their reported dental health behaviour.
Design . Standardized epidemiological dental examination and structured interview.
Setting . Paediatric HIV outpatient department in a South London hospital.
Study population . HIV-positive children attending the above outpatient clinic over a 6-month period (30 subjects) and parents (20 informants).
Methods . Epidemiological examination of children was undertaken by one trained and calibrated examiner to determine caries prevalence using dmft/DMFT. Parents were interviewed to obtain information on their children's dental health behaviour: tooth-brushing, diet, fluoride; oral medication and dental attendance were explored.
Results . Sixty-three per cent ( n  = 19) of children had dental caries experience, much of it untreated. Mean dmft/DMFT was 4·4. Sixty per cent ( n  = 18) of all children presented with active or untreated caries and the care index for those at/under age 5 years was low (10%). Unfavourable dental health behaviour included: consumption of nonmilk extrinsic sugars at night, use of sugar-based medications, low fluoride intake, late commencement of toothbrushing and poor dental attendance. Dental health was not considered a priority for many of these children. Parents did not necessarily disclose their child's HIV status on dental attendance.
Conclusion . Caries prevalence was high, much of the disease untreated, and unfavourable dental health behaviour, including the use of sugar-based medicines was common. HIV infected children should be considered a high caries risk and receive appropriate dental care, in terms of both treatment and preventive services, following confirmation of seropositivity.
