Brief Summary

This is a questionnaire based study investigating the relationship between the timing of dietary acid intake toothbrushing and erosive tooth wear. Data will be collected on the timing, nature, frequency and duration of dietary acid intakes and timing and frequency of the participants toothbrushing. Signs of the participants erosive tooth wear will then be recorded

Conditions

Tooth Wear

Outcome Measures

Primary Outcomes (1)

• Basic Erosive Wear Examination

  Each tooth will be graded by the extent of the surface which the acid has damaged. The Basic Erosive Wear Examination (BEWE) index will grade tooth wear on the buccal, occlusal and palatal/lingual surfaces of each tooth excluding third molars. This ordinal scale graded tooth wear from 0 to 3 (0 = no wear, 1 = early surface loss, 2 = surface loss \< 50% or specific defect, 3 = surface loss \> 50%). The worst score in each sextant will be taken to be the sextant score. A cumulative score will be calculated for the mouth by adding each sextant score, which can range from 0-18. A higher score indicates a higher level of erosive tooth wear (worse outcome)

  Single reading of wear of the teeth at the appointment date. Examination of wear takes 5 minutes

Study Arms (2)

Severe Tooth Wear

Severe tooth wear with a BEWE score of 12 and at least one score of 3 in three quadrants Adult 18 years or older No missing anterior teeth Minimum of at 10 teeth in the upper and 10 teeth in the lower jaw No anterior crowns/ bridges or implants Written consent to the study There was no intervention - just a questionnaire for each group

Without Tooth Wear

BEWE score of 10 or lower and no score of 3 on any surface of any tooth (clinically classified as no or mild erosive tooth wear) Adult 18 years or older No missing anterior teeth Minimum of at 10 teeth in the upper and 10 teeth in the lower jaw No anterior crowns/ bridges or implants Written consent to the study There was no intervention - just a questionnaire for each group
