Abstract

To evaluate the influence of calcium hydroxide (CH) paste used as intracanal medication on the bond strength of AH Plus (AH) and Epiphany (EP) sealers to root dentin. Sixty palatal canals were prepared in human maxillary first molars, using a rotary system. Half of the specimens received distilled water, and the other ones received intracanal medication with CH for 14 days. Thereafter, the CH was removed and both groups were further divided into two subgroups, filled with either AH or EP. The test specimens were submitted to the micropush-out test at a speed of 0.5 mm min(-1) . Results were statistically analyzed with anova and Tukey's test at a 95% confidence level. The use of CH had statistically significant (P < 0.05) influence on AH only, increasing its bond strength from 19.7 ± 4.5 to 23.8 ± 2.5 (mean ± SD in MPa). In both EP groups, with (1.8 ± 0.5 MPa) and without (1.5 ± 0.9 MPa) CH, the bond strength values were statistically significantly lower than in either of the AH groups (P < 0.05). Calcium hydroxide used as intracanal medication for 14 days had a positive influence on the bond strength of AH to root dentin whereas the effect on EP was insignificant. Regardless of the intracanal medication used, AH showed consider...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
