Association Between Erosive Tooth Wear Progression and Dietary Risk Factors.

Study to determine if whether or not exist an association between the tissue loss (ETW progression) and the frequency of an acidic diet. To accomplish the aim, a quantitative analysis of intraoral scans of study models will be performed to identify erosive tooth wear progression in a group of Chilean adolescents.

First, participants with different intake of dietary acids will be compared in terms of their baseline sociodemographic and clinical characteristics. Second, the association between baseline frequency of dietary acids and changes in volume loss over time will be evaluated using linear mixed models to account for the data structure (repeated assessments nested within teeth and teeth nested within children). Models will be adjusted for demographic factors, family socioeconomic position, health behaviours and chronic conditions.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male and female (age range 10-18) assisting in a school with low socioeconomic status.

They must have: -Complete record of questionnaires

  • Baseline and Follow-up Intra oral scanners (with correct alignment when using Wearcompare software)
  • BEWE scores
  • Signed Inform consent

Exclusion criteria

  • Patients not willing to participate
  • Patients wearing orthodontic appliances

Treatment and study plan

No intervention, (observational study).

Other

From every participant the following information was recorded for further analysis:

  • BEWE score- Basic erosive tooth wear examination (from 2 calibrated examiners) to diagnose the presence of erosive tooth wear.
  • Their answer to a validated questionnaire assessing the dietary habits based in the frequency of acidic diet.
  • 2 Intra oral scans (IOS): Baseline and follow up (1 year after baseline) to perform a quantification of tissue loss (in Volume loss per mm3) using Wearcompare software.

Primary outcomes

  1. Volume loss

    Time frame: 14 months

    Volume Loss in mm3 in patients having a frequent consumption of dietary acids (cut off to decide) Volume loss will be determined by aligning the marker teeth of each participant: 1.1-2.1-1.6-2.6-3.6 and 4.6.

Secondary outcomes

  1. Dietary Risk factors

    Time frame: 14 months

    Frequency of consumption of dietary acids (Possible cut off: > 1 a day)
