Abstract
Relative influence of brushing force transmission factors on substance loss of eroded dentine
Highlights
Dental erosion is chemical wear as a result of extrinsic or intrinsic acids or chelators acting on plaque-free tooth surfaces and dissolution of tooth by acids when the surrounding aqueous phase is undersaturated with respect to tooth mineral [1]
There were no significant differences in the average thickness of substance loss between the two areas, indicating that the dentine-abrading action
Eroded dentine wear with a sonic toothbrush was significantly deeper with a tapered tip (3.82 ± 2.73) than with a flat trim (2.40 ± 1.54) (Figure 4)
Summary
Dental erosion is chemical wear as a result of extrinsic or intrinsic acids or chelators acting on plaque-free tooth surfaces and dissolution of tooth by acids when the surrounding aqueous phase is undersaturated with respect to tooth mineral [1]. Clinical [10], in situ [4,9,11] and in vitro [5,6,7,8] studies have been conducted to understand the complex nature of erosive dentine wear In these studies, various techniques that were used to assess the mineral loss of dental hard tissues, such as microradiography [6,7], microhardness test [8], surface 3D topography [8] and scanning electron microscopy [7] have been applied to evaluate the influence of acid on dentine loss and the assessment of erosive dentine wear by toothbrushing. The former could detect surface roughness and substance loss of eroded dentine by scanning specimens with a laser beam and the latter by loading the contact stylus laterally across specimens for a specified distance and specified contact force
