Abstract:

The microgap formation associated with hydrophilic and hydrophobic root canal obturation systems is of interest. Hence, thirty extracted human single-rooted teeth were randomly divided into two groups (n=15 each): Group I - obturated (Resilon with Epiphany sealer) and Group II - obturated hydrophobic system (Gutta-percha with AH Plus sealer). After obturation, the samples and microgaps were evaluated using scanning electron microscopy (SEM) at 2000x magnification. Group I (hydrophilic) showed a significantly lower mean microgap of 2.36 ± 0.52 µm, while Group II (hydrophobic) exhibited a higher mean microgap of 5.81 ± 0.89 µm. Thus, hydrophilic obturation systems showed superior sealing ability with minimal microgap formation compared to hydrophobic systems.

Cavity Drainage and Flashings in Masonry walls

Typically, a cavity wall consists of two wythes separated by a gap of at least 2 inches, which may contain insulation while still maintaining a minimum clear space of 1 inch to facilitate adequate drainage. Advanced methods like the insertion of a continuous drainage mat can further reduce this space while ensuring effective moisture expulsion.
Weep holes, strategically placed at the base of the cavity, are critical for draining accumulated water. These openings are created by leaving head...
