Surface characteristic changes of dental ceramics after cyclic immersion in acidic agents and titratable acidity.
The potential erosive effect of acidic food, sour fruits and drinks on all-ceramic restorations used in dentistry has not been clearly documented. Surface characteristic changes have been evaluated and compared for disc-shaped specimens (diameter 12.0 mm and thickness 2.0 mm) of fluorapatite-leucite and fluorapatite ceramics using various storage agents (deionized water, citrate buffer solution, pineapple juice, green mango juice, cola soft drink and 4% acetic acid). Immersion in pineapple juice, green mango juice, cola soft drink and 4% acetic acid for 16 hours produce significant increases in surface roughness for both types of ceramics investigated.
