Dietary acid intake and intrinsic acid exposure not linked to erosive tooth wear progression

Results:

• A total of 295 dental surfaces (131 incisors and 164 molars) in 70 patients were analysed for this study.
• The mean age of participants at baseline was 15.0 years (SD: 0.79), and the average time between scans was 11.8 months (1.61 SD; range 10-13).
• The mean volume loss per mm2 of dental surfaces was -0.013 mm3 (SD: 0.009).
• Greater volume loss was observed among adolescents with higher baseline BEWE scores and those whose parents had lower education as well as on molar than incisor surfaces.
• No associations were found with dietary acid intake and intrinsic acid exposure when baseline levels of tooth wear, parental education and other factors were controlled for.

The findings help to characterise groups at greater risk of ETW and would indicate that improved screening and upstream preventative measures should form the basis of a preventative program. Intra-orals scans and registration software might improve the ability to diagnose, monitor and prevent the early loss of dental hard tissue.
