Purpose:
To compare the punch resistance of VariGlass and Vitrebond.
Materials And Methods:
Discs measuring 1.4 cm in diameter and 1.5 mm thick of VariGlass (VG) and Vitrebond (VT) light-activated lining materials, were prepared and submitted to punch testing in a universal testing machine at 7 minutes, 30 minutes and 24 hours after mixing.
Results:
VG showed higher resistance to punch testing than the VT in the three periods evaluated (P< 0.01). The results were further compared to previous data obtained from three calcium hydroxide lining cements which gave much lower values than VG and VT (P< 0.01).

For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in ASTM C...

Using the ICE table and substituting the Kb value, we calculate the initial pH of 50 mL of 0.1 M ammonia to be 11.11. Addition of 25 mL of 0.1 M hydrochloric acid to this solution of ammonia results in a buffer with an equal concentration of ammonia and ammonium ions. The pH of this buffer can be calculated by substituting these...
