Ibicuruzwa

Mu rwego rwo gusobanura neza uburyo bwambere bwo gucukura dentin, hasuzumwe ingaruka zo guhagarika 1-hydroxyethylidene-1,1-bisphosifone (HEBP) ku myunyu ngugu ya dentin.Imbeba (100 g) zatewe mu buryo bwihishwa na HEBP (8 mg P / kg) kuri 7 cyangwa 14 d, hanyuma ibice bitunganyirizwa kuri Ca histochemie na / cyangwa microscopi ya electron.HEBP ivura incisors yerekanaga urwego rumeze nkurunani rwimirongo ya minisiteri yubucukuzi bwamabuye y'agaciro na minisiteri ya minisiteri kumpera ya apical.GBHA yerekanye Ca itagereranywa muri matrike ya minisiteri idafite amabuye y'agaciro aho microscopi ya electron yerekanaga ikwirakwizwa ryinshi rya meshi imeze nka electron-yuzuye.Matrix ya minisiteri idafite imyunyu ngugu yari mibi kuri Ca ariko yarimo imitsi myinshi ya matrixs (MVs) yuzuyemo kristaline na / cyangwa amabuye y'agaciro ya amorphous.Mineralisation ya circumpulpal dentin yabayeho itisunze MV ikungahaye kuri mantle dentin igaragara mubigero byagize ingaruka.Amakuru yacu atanga ibimenyetso bya histochemiki yumutungo ushobora kuba Ca-guhuza matrike ya circumpulpal dentin no kuba idahari muri mantle dentin aho MV-yunganirwa na minerval.Muri mantine dentin, HEBP ntabwo ibangamira imikurire ya kirisiti muri MV ahubwo ibuza gukura kwayo nyuma yo guturika.Hifujwe ko matrike ya circumpulpal dentin ifite ubushobozi bwo gucukura amabuye y'agaciro ititaye kuri MV yunganirwa na minant dentin, nubwo MV igena ahantu hambere nigihe cyo gucukura dentine.
