Abstract

Background

Tooth wear and acid erosion have not been previously investigated in Jordanian schoolchildren.

Aim

To determine the prevalence of tooth wear and associations for a range of dietary and behavioural risk factors.

Methods

A sample of 1,602 children aged between 15 and 16 years were randomly selected from 32 schools in Amman, Jordan. Tooth wear was measured using the modified Tooth Wear Index and dichotomised on the presence or absence of exposed dentine. Analysis of questionnaire items was performed by multiple logistic regression analysis.

Results

Dentine was exposed in 51 % of children, and males (59 %) had significantly more tooth wear than females (42 %), OR = 1.9, 95 % CI 1.6, 2.4, p < 0.0001. Over 40 % of children had dentine exposed occlusally, mainly the lower first molars, and less than 1 % of the children had dentine exposed palatally. Daily consumption of oranges, ketchup, olives and sweetened coffee was associated with tooth wear through enamel to expose dentine. Carbonated drinks (fizzy) were on the borderline of significance at p = 0.055. The mean DMFT (5.52) was significantly greater in children without tooth wear compared to children with tooth wear (4.13) (p < 0.001). DMFT, gender, daily consumption of oranges and daily consumption of ketchup were significantly associated with tooth wear in the multiple regression model.

Conclusion

In this sample of children resident in Amman, Jordan, males had significantly more tooth wear than females. The acidic dietary items associated with tooth wear and, thus, dental erosion included oranges, olives and tomato ketchup.

Acknowledgments

The authors wish to thank all the school authorities for their enthusiasm and willingness to facilitate this study. Especial thanks must go to the children themselves. This study would not have been possible without the financial support from The British Council and The Deanship of Academic Research at The University of Jordan.
