N'ihi nhọrọ ọgwụgwọ dị iche iche, dentine hypersensitivity (DH) bụ ọrịa na-egbu mgbu na ihe ịma aka ụlọ ọgwụ. Dị ka ihe ngwọta nwere ike ime, a chọpụtala lasers dị elu. Emebere nnwale ụlọ ọgwụ a iji nyochaa mmetụta Er:YAG na Er,Cr:YSGG lasers na DH. A na-ahazi ya, na-achịkwa ma kpuo ìsì abụọ. Ndị sonyere 28 na otu ọmụmụ ihe niile mezuru ihe achọrọ maka nsonye. A na-atụle mmetụta uche site na iji ihe nlele analog nke anya tupu ọgwụgwọ dịka ntọala, ozugbo tupu ọgwụgwọ na mgbe ọgwụgwọ gasịrị, yana otu izu na otu ọnwa na-esote ọgwụgwọ.
