I-Er, Cr YSGG Ihlinzeka Nge-Laser Crystal Esebenzayo

Ngenxa yezinketho zokwelashwa ezihlukahlukene, i-dentine hypersensitivity (DH) yisifo esibuhlungu kanye nenselele yomtholampilo. Njengesixazululo esingaba khona, kuye kwacwaningwa ama-laser anamandla kakhulu. Lesi sivivinyo somtholampilo sakhelwe ukuhlola imiphumela yamalaser e-Er:YAG kanye ne-Er,Cr:YSGG ku-DH. Yayingahleliwe, ilawulwa, futhi iyimpumputhe kabili. Ababambiqhaza abangama-28 eqenjini locwaningo bonke banelise izidingo zokufakwa. Ukuzwela kukalwa kusetshenziswa isikali esibonakalayo se-analogue ngaphambi kokwelashwa njengesisekelo, ngokushesha ngaphambi nangemuva kokwelashwa, kanye nesonto elilodwa nenyanga eyodwa ngemva kokwelashwa.

Akukho mehluko phakathi kokuzwela kokwelashwa kwangaphambili okuye kwabonwa ukuze kuvuselelwe umoya noma uphenyo. Ukukhuthazwa kokuhwamuka kwehlise izinga lobuhlungu ngemva nje kokwelashwa, kodwa amazinga ahlala engashintshile ngemva kwalokho. Inani elincane lokungaphatheki kahle libonwe ngemva kokushiswa kwelaser kwe-Er:YAG. Iqembu le-4 libone ukunciphisa okukhulu kakhulu kobuhlungu ngokukhuthazwa komshini ngaso leso sikhathi, kodwa ngokuphela kocwaningo, amazinga obuhlungu akhuphukile. Phakathi namaviki angu-4 okulandelwa komtholampilo, amaqembu 1, 2, kanye ne-3 abonise ukwehla kobuhlungu obuhluke kakhulu kuneqembu le-4. I-Er: YAG ne-Er, Cr: YSGG lasers iyasebenza ekwelapheni i-DH, nakuba akukho ukwelashwa kwe-laser okuhloliwe okwakwazi ukuqeda ngokuphelele ubuhlungu, ngokusekelwe kulokho okutholakele nangaphakathi kwemingcele yalolu cwaningo.

I-YSGG (yttrium yttrium gallium garnet) ehlanganiswe ne-chromium ne-uranium inikeza ikristalu ye-laser esebenza kahle yokwenza ukukhanya kuma-microns angu-2.8 kubhendi ebalulekile yokumunca amanzi.
