introdouction: dentinal hypersensitivity (dh) is one of the most painful chronic problems reported in dental offices. various methods have been applied for the treatment of dh. however, majority of them are either ineffective or last for a short period of time. it has been reported that lasers, particularly neodymium- doped: yttrium aluminum garnet laser (nd: yag), can be helpful in the treatme...

The effect of the pulse envelope on electron-positron pair creation in a circularly polarized laser is investigated. Interference length scale envelope, and smoothness edges are found to influence spectrum. A toy model flat-top used identify effects inaccessible local approaches. Broadening channel openings widening energy transverse momentum distribution receive contributions that below harmon...
