Chifukwa cha njira zosiyanasiyana zochiritsira, dentine hypersensitivity (DH) ndi matenda opweteka komanso vuto lachipatala. Monga yankho lomwe lingathe, ma lasers apamwamba kwambiri adafufuzidwa. Chiyeso chachipatalachi chinapangidwa kuti chiwone zotsatira za Er:YAG ndi Er,Cr:YSGG lasers pa DH. Zinangochitika mwachisawawa, zolamulidwa, komanso zakhungu ziwiri. Otenga nawo gawo 28 mu gulu la kafukufuku onse adakwaniritsa zofunikira pakuphatikizidwa. Kukhudzika kwake kunayesedwa pogwiritsa ntchito sikelo yowona ya analogue musanalandire chithandizo ngati choyambira, nthawi yomweyo musanalandire chithandizo ndi pambuyo pake, komanso sabata limodzi ndi mwezi umodzi mutalandira chithandizo.
