Thermal modelling of micropulsed diode laser retinal photocoagulation.

abstract：BACKGROUND AND OBJECTIVES:Many studies of laser-induced thermal decomposition of dental enamel have demonstrated a reduction in the rate of acid dissolution, size of artificial caries-like lesions, and acid reactivity. Additionally, studies have correlated the loss of carbonate from dental enamel with a reduction in ac...
