Conclusions There is weak evidence indicating length and width of EMCs increase following bracket removal and the scientific evidence concerning quantitative evaluation of the number parameter before and after debonding is insufficient .
However , there is a strong evidence that after debonding the number of EMCs is likely to increase .
Objectives To evaluate and compare the enamel microcracks ( EMCs ) characteristics ( qualitative and quantitative ) in the form of tooth damage before and after debonding from human teeth of in vitro studies .
How Is the Enamel Affected by Different Orthodontic Bonding Agents and Polishing Techniques?
Objectives : The objective of this study was to assess the effect of new bonding techniques on enamel surface . Material s and Methods : Sixty upper central incisors were r and omly divided into two equal groups . In the first group , metal brackets were bonded using TransbondXT and , in the second group , the same brackets were bonded with Maxcem Elite . The shear bond strength ( SBS ) of both agents to enamel was measured and the number and length of enamel cracks before bonding , after debonding and after polishing were compared . The number of visible cracks and the adhesive remnant index ( ARI ) scores in each group were also measured . Results : There were significantly more enamel cracks in the Transbond XT group after debonding and polishing compared to the Maxcem Elite group . There was no significant difference in the length of enamel cracks between the two groups ; but , in each group , a significant increase in the length of enamel cracks was noticeable after debonding . Polishing did not cause any statistically significant change in crack length . The SBS of Maxcem Elite was significantly lower than that of Transbond XT ( 95 % confidence interval ) . Conclusion : Maxcem Elite offers clinical ly acceptable bond strength and can thus be used as a routine adhesive for orthodontic purpose s since it is less likely to damage the enamel
