Er, Cr YSGG Imapereka Crystal Yabwino Ya Laser
Mafotokozedwe Akatundu
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.
Palibe kusiyana pakati pa zomverera za pretreatment zomwe zidawoneka pakukondoweza kwa mpweya kapena kafukufuku. Kukondoweza kwa evaporative kunachepetsa kuchuluka kwa ululu atangolandira chithandizo, koma milingoyo idakhazikika pambuyo pake. Kusapezako pang'ono kunawoneka pambuyo pa kuyatsa kwa laser ya Er:YAG. Gulu la 4 linawona kuchepetsa kupweteka kwakukulu ndi kukondoweza kwa makina nthawi yomweyo, koma pamapeto a kafukufuku, milingo yowawa idakwera. Pamasabata a 4 akutsata zachipatala, magulu a 1, 2, ndi 3 adawonetsa kuchepa kwa ululu womwe unali wosiyana kwambiri ndi wa gulu la 4. The Er: YAG ndi Er, Cr: YSGG lasers ndi othandiza pochiza DH, ngakhale palibe chithandizo cha laser chomwe chinayesedwa chomwe chinatha kuthetsa ululu wonse, kutengera zomwe zapeza komanso mkati mwa magawo a phunziroli.
YSGG (yttrium yttrium gallium garnet) yopangidwa ndi chromium ndi uranium imapereka kuwala kokwanira kwa laser crystal pakupanga ma microns 2.8 mu bandi yofunikira yamayamwidwe amadzi.
Ubwino wa Er,Cr: YSGG
1.Kutsika Kwambiri Kwambiri ndi Kutsika Kwambiri Kwambiri (1.2)
2.Nyali yonyezimira imatha kupopa ndi Cr band, kapena diode imatha kupopedwa ndi Er band
3.Imapezeka mosalekeza, momasuka kapena Q-switched
4.Kusokonezeka kwachilengedwe kwa crystalline kumawonjezera kukula kwa mzere wa pampu ndi scalability
