Association Between Erosive Tooth Wear Progression and Dietary Risk Factors.

Study Overview
=================
Brief Summary
-----------------
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.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Other: No intervention, (observational study).|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.|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Volume loss | 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. | 14 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dietary Risk factors | Frequency of consumption of dietary acids (Possible cut off: > 1 a day) | 14 months |
