Er, Cr YSGG Ibonelela ngeCrystal esebenzayo yeLaser

Ngenxa yeendlela ezahlukeneyo zonyango, i-dentine hypersensitivity (DH) isifo esibuhlungu kunye nomngeni wekliniki. Njengesisombululo esinokubakho, iilaser ezibukhali kakhulu ziye zaphandwa. Olu lingo lwezonyango lwenzelwe ukuhlola iziphumo ze-Er:YAG kunye ne-Er, Cr:YSGG lasers kwi-DH. Yayingacwangciswanga, ilawulwa, kwaye iyimfama kabini. Abathathi-nxaxheba abangama-28 kwiqela lophononongo bonke banelise iimfuno zokubandakanywa. Uvakalelo lwalinganiswa kusetyenziswa isikali se-analogue esibonakalayo phambi konyango njengesiseko, ngokukhawuleza ngaphambi nasemva konyango, kunye neveki enye kunye nenyanga enye emva konyango.

Akukho mahluko phakathi kobuthathaka bonyango lwangaphambili lubonwe nokuba luvuselelo lomoya okanye lophando. Ukuvuselela i-evaporative kunciphisa inqanaba leentlungu kanye emva konyango, kodwa amanqanaba ahlala engaguquki emva koko. Olona bungakanani buncinci bokungakhululeki bubonwe emva kwe-Er:YAG laser irradiation. Iqela le-4 libone ukuncipha okukhulu kwentlungu kunye nokuvuselela komatshini kwangoko, kodwa ngokugqitywa kophando, amanqanaba entlungu aphakanyisiwe. Ngethuba leeveki ze-4 zokulandelwa kwekliniki, amaqela e-1, i-2, kunye ne-3 abonise ukuncipha kweentlungu ezihluke kakhulu kwiqela le-4. I-Er: YAG kunye ne-Er, i-Cr: i-YSGG lasers iyasebenza ekuphatheni i-DH, nangona akukho nolunye unyango lwe-laser oluvavanywayo lwakwazi ukuphelisa ngokupheleleyo intlungu, ngokusekelwe kwiziphumo kunye nangaphakathi kweeparitha zolu pho nonongo.

I-YSGG (i-yttrium yttrium gallium garnet) efakwe i-chromium kunye ne-uranium ibonelela ngekristale yelaser esebenzayo kwisizukulwana sokukhanya kwi-2.8 microns kwibhendi ebalulekileyo yokufunxa amanzi.
