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

Dietary acid intake and intrinsic acid exposure not
associated with erosive tooth wear progression, according to a recent study published in the
Journal of dentistry.

The aim of this study was to determine predictors of erosive
tooth wear (ETW) progression, using novel primary-care quantitative analysis

In a single-centre, prospective, observational cohort
longitudinal study, adolescents, aged 11-18 years, underwent a baseline BEWE
examination, validated risk factors questionnaire and baseline intraoral scan
(IOS, TRIOS 3.0, 3Shape, Copenhagen, Denmark). One year later a repeat scan was
taken. Quantitative analysis of wear progression (volume loss) on first
permanent molars and upper central incisors was performed using previously
published protocols. Multilevel linear regression was used to investigate the
associations between baseline predictors and volume loss per mm2.


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.
