Intraoral Scanner use may help detect erosive Dental Wear : Study

Thirty six 1 mm thick enamel samples were luted to labial surfaces of sound extracted anterior teeth. Baseline scans of the specimens were made by intraoral scanner (Carestream 3700) and 3D confocal microscope (KEYENCE VK-X100). Each enamel sample had a reference area created by applying a protective tape then the teeth were immersed in citric acid of 1% concentration (ph.: 2.7). After 1, 3and 6 hours teeth were removed and brushed with an electrical tooth brush for 2 minutes.

To determine the enamel loss each follow-up scan was superimposed with the baseline scan and measured with the tools of the intraoral scanner’s software. Same procedures were performed under the 3D confocal laser microscope where height difference between eroded and reference surfaces was measured. Values obtained were statistically analyzed.
