| dc.description.abstract | ABSTRACT Background Teeth restored with direct composite resin are constantly exposed to specific challenges of the oral cavity. These challenges can modify the material properties and, when associated with daily brushing, eventually change its surface roughness, allowing bacterial growth and retention of extrinsic pigments. Dentifrices plays an important role in dental wear (abrasion) and over time, can also cause an increase in the surface roughness of restorative materials. Objective To assess the effect of dentifrices on the longevity of direct nanofilled composite resins restorations as far as wear and roughness is concerned. Method Class V cavity were prepared on 90 extracted human teeth and restored with Filtek Z350 composite. Teeth were randomly divided into 6 experimental groups of 15 each labelled as Group-1 (Colgate Dental cream) Group-2 (Colgate Active Salt toothpaste), Group-3 (Pepsodent Regular toothpaste), Group-4 (Dabur red toothpaste), Group-5 (Dabur Lal tooth powder) and Group-6 Control (water). The samples were fixed on tooth brushing machine and subjected to mechanical tooth brushing using various dentifrices according to respective groups in 3 phases and reading of surface roughness (Ra) was recorded. Result Surface roughness (Ra) had increased in following order: Group 6 < Group 3 < Group 2 < Group 1 < Group 4 < Group 5. All the tooth pastes were compared, their behaviour was found to be similar as there was no statistically significant difference amongst them. Though all of them were inferior to control group and the difference was statistically significant. Whereas the only tooth powder Dabur lal tooth powder gave the maximum roughness when compared with the other tooth pastes and the difference was statistically significant. Conclusion With increase in time of brushing there was increase in surface roughness in all the 5 dentifrices among them Ra was maximum for Dabur lal tooth powder.
