Nekuda kwemhando dzakasiyana-siyana dzekurapa, dentine hypersensitivity (DH) chirwere chinorwadza uye dambudziko rekiriniki. Semhinduro inogona kuitika, yakakwirira-yakasimba lasers yakatsvakwa. Uyu muyedzo wekiriniki wakagadzirirwa kuongorora mhedzisiro yeEr:YAG uye Er,Cr:YSGG lasers paDH. Yakanga isina kurongeka, yakadzorwa, uye yakapetwa kaviri. Vatori vechikamu makumi maviri nevasere vari muboka rezvidzidzo vese vakagutsa zvinodiwa kuti vabatanidzwe. Sensitivity yakayerwa pachishandiswa chiyero chekuona analogue pamberi pekurapa sekutanga, nguva isati yasvika uye mushure mekurapwa, pamwe nevhiki imwe nemwedzi unotevera kurapwa.
