Profilometry was not suitable for measuring mineral loss, unless the organic material was removed. The results of this study do not lend support to the notion that brushing increases substance loss of eroded dentine. ![]() When the organic material was removed enzymatically, all methods gave comparable results. P-O yielded the lowest (7.0 +/- 3.4 microm) and LMR the highest (109.8 +/- 10.7 microm) substance loss values. Surface changes (smoothing) One sign of dental erosion. Considerable differences occurred, however, when results from the different methods were compared. Teeth that appear thin and translucent are a sign that tooth enamel erosion may have already begun. For substance loss, there was no significant difference between eroded and eroded/abraded samples. Eroded teeth can become translucent, yellow (thats the dentin showing through), develop rounded edges, and become sensitive to hot and cold foods and. The SEM images showed that a demineralized organic layer had developed, which was unaffected by brushing. ![]() The effects of brushing were investigated by optical (P-O) and mechanical (P-M) profilometry, by longitudinal microradiography (LMR), and by scanning electron microscopy (SEM). Eroded or worn enamel is what causes teeth to take on a translucent appearance. Therefore, the present study sought (i) to investigate the effects of toothbrushing on eroded dentine and (ii) to analyze how the organic matrix influences the outcome of established methods for quantifying dental hard tissue loss. Only a few studies have aimed to show this for dentine and, if so, disregarded the complex histological structure of this tissue. Enamel erosion can be caused by the following: Having too many soft drinks, which have lots of phosphoric and citric acids. ![]() Certain medical conditions can influence the development and the potency of the enamel. It is an established assumption that eroded dental hard tissues are particularly prone to toothbrush abrasion. To put it in simple words, translucent teeth happen because of eroded enamel.
