Changes in the pH level of saliva when prosthetics of edtless jaws with various base plastics

Ertesyan A. R.

In this study, we studied the change in the pH level in unstimulated saliva of the sublingual gland before and after the application of complete removable plate prostheses made of photopolymer resins for 3D printing and acrylic plastics. The best result was observed in patients with complete removable dentures made of: Denture 3D + - 6.59±1.24 and 6.65±1.24, 7 and 21 days, respectively; Denture Base, 7 days - 6.71±0.98, 21 days - 6.64±1.28. Having conducted a study to study the pH values in the unstimulated saliva of the hyoid gland, it can be concluded that the pH of saliva in patients with complete removable dentures made of photopolymer resins for SLA printing on a Denture 3D+ 3D printer, Denture Base on days 7 and 21 is statistically and reliably less than Ftorax and Rapid Simplified hot curing plastics.
