Self etching primer (SEP) saves valuable time by eliminating the multiple steps required to place a sealant prior to bonding brackets. The purpose of this study is to compare the resistance to demineralization between SEP and a conventional sealant. 25 patients were bonded with either SEP or Sealant using the split arch technique. At the end of the observation period (18--24 months), the plaque index and decalcification scores were noted. Data was analyzed using ANOVA and Tukey Kramer test. Significantly higher decalcification score was found with the SEP group as compared with the Sealant Group (p < 0.001). Significant difference was also found between the level of hygiene compliance and decalcification (p < 0.0001). Patients with fair or poor hygiene compliance have higher decalcification scores with SEP as compared to Sealant. These results suggest that application of a self etching primer saves chair time but provides less resistance to enamel demineralization as compared to a conventional sealant.

The propose of this dye and SEM study was to evaluate the cleansing capabilities of two solvents ethyl alcohol and chloroform, prior to dentin bonding in the coronal chambers of endodontically treated teeth obturated with either a eugenol or resin-based sealer. A total of 156 extracted human molar teeth were divided into 6 groups and obturated with either a eugenol-based (Roth's, Grossman), or a resin-based (AH Plus, Kerr) endodontic sealer. Samples were thermocycled and placed into India Ink or silver nitrate for (SEM samples). All teeth were cleared and evaluated for coronal microleakage. A significant difference was found between the …
