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. Ukuvuselelwa kwe-evaporative kunciphisa inqanaba leentlungu kanye emva konyango, kodwa amanqanaba ahlala engaguquki emva koko. Ubuncinci bokungonwabi 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: ii-lasers ze-YSGG ziyasebenza ekuphatheni i-DH, nangona akukho nanye unyango lwe-laser oluhlolisisiweyo lukwazi ukuphelisa ngokupheleleyo intlungu, ngokusekelwe kwiziphumo kunye nangaphakathi kwesi sifundo.

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.
