Purpose: To assess the effects of experimental titanium tetrafluoride (TiF4) varnish and commercial sodium fluoride (NaF) varnish with CO2 laser on enamel hardness.
Materials And Methods: Ninety human enamel samples were randomly assigned to one of the following groups: 1. control (no treatment) (CO); 2.
Purpose: The purpose of this in vitro study was to evaluate the irradiation efficacy of the CO(2) laser and the Er, Cr:YSGG laser-either unassisted or assisted by acidulated phosphate fluoride (APF) treatment-on enamel's acid resistance.
Methods: One hundred twenty enamel samples, obtained from 20 extracted human molars, were randomly assigned to 6 groups as follows: (1) control (C); (2) exposed to acidulated phosphate fluoride (APF) gel (F); (3) Er, Cr:YSGG laser (EL); (4) irradiated with Er, Cr:YSGG laser through APF gel (EL/F); (5) CO(2) laser (CL); and (6) irradiated with CO(2) laser through APF gel (CL/F). The specimens were individually demineralized in an acidified hydroxyethylcellulose system, and the acid resistance was evaluated by determining the calcium ion using atomic absorption spectrometry.
