Abstract
Abstract Aim: This in vitro study was carried out to evaluate the efficiency of abrasive versus nonabrasive optical based whitening tooth pastes. Methods: A total of 30 sound extracted bovine teeth were sectioned, mounted in acrylic block and randomly divided into 3 groups I-III (water (control), abrasive optical whitening tooth paste (Closeup Diamond Attraction), nonabrasive optical whitening tooth paste (Closeup White Now)) respectively. The buccal surface of each sample was flattened and stained by immersion into a concentrated tea solution. Then samples were subjected to 5500 double strokes of brushing with 200g force using a brushing simulator. Tooth color and surface roughness were measured before and after the brushing procedure using reflecting spectrophotometer regarding (CIE) and a contact profilometer surface roughness tester. Results: For color, both whitening tooth pastes showed a statically significant means of ΔE1 and ΔE2 compared to the control group indicating a higher efficiency. Furthermore, all groups showed a statistically significant increase in roughness after brushing. On the other hand, they showed a non-statistically significant means compared to each other. Conclusions: Both types of pastes were effective in teeth whitening without creating potential harmful to surface of enamel for a time equivalent to one year usage in oral cavity.
