Changes in oral health over ten years amongst UK children aged 4-5 years living in a deprived multiethnic area

Objective To examine the changes over a decade in caries experience amongst children aged 4-5 years living in a deprived multiethnic community in the United Kingdom. Design Cross-sectional surveys. Setting Schools and nurseries in the Old Trafford area, Manchester, England , 1989, 1990, 1991 and 1998. Main outcome measures Mean dmft, oral cleanliness and proportion of childre n with rampant caries. Results The unadjusted Odds Ratio for caries free children examined in 1998 compared with children examined prior to 1998, was only significant amongs t the white group. White children examined in 1998 were over three times mo re likely to be caries free than white children examined previously. South Asian children whose mothers were non English speaking examined in 1998 wer e almost twice as likely to have good/fair oral cleanliness than those exam ined prior to 1998. Moreover, South Asian children whose mothers were non-E nglish speaking in 1998 were over three times more likely not to have rampa nt caries than their counterparts in the earlier years. Conclusion There were significant improvements in caries and oral health am ongst white children over the decade, and although less marked these were m irrored amongst South Asian children.
