【摘要】：【目的】研究以鈣磷為基礎(chǔ)的含鋅、氟離子礦化液對牙釉質(zhì)理化性能的影響。【方法】將因治療需要而拔除的成人第三磨牙牙冠制作成牙釉質(zhì)切片。分別以含不同濃度氟離子和鋅離子的鈣磷飽和礦化液處理牙釉質(zhì)切片,分為處理組:Ca P-Zn F、Ca P-F、Ca P-Zn、Ca P組和雙蒸水DDW對照組。采用掃描電鏡、X射線衍射儀和紅外光譜儀,檢測礦化液處理組和對照組牙釉質(zhì)切片的表面特性。【結(jié)果】掃描電鏡觀察到經(jīng)礦化液處理后的牙釉質(zhì)切片表面有聚集的微晶沉積。X射線衍射儀分析牙釉質(zhì)表層沉積的羥基磷灰石晶體顯示,含氟離子組和同時含有鋅、氟離子組礦化液與含鋅離子組或?qū)φ战M相比,晶粒增大、晶體完整性增高及沉積量增多。含氟離子組和同時含有鋅、氟離子組礦化液處理的牙釉質(zhì)表面紅外光譜儀圖譜分析,結(jié)果顯示在1102、1065、1027 cm-1處呈現(xiàn)多個P-O(磷酸組)吸收峰�！窘Y(jié)論】含有鈣離子、磷酸根離子、鋅離子和氟離子的礦化液可以在牙釉質(zhì)表面形成具有保護功能的載鋅氟磷灰石晶體層,從而具有防治早期牙釉質(zhì)齲的作用。
[Abstract]:[objective] to study the effect of zinc and fluorine mineralized solution based on calcium and phosphorus on the physical and chemical properties of enamel. Enamel sections were treated with calcium phosphate saturated mineralized solution containing different concentrations of fluorine and zinc ions respectively. The sections were divided into two groups: the treatment group: 1 Ca P-Zn FU Ca P-FU Ca P-ZnN Ca P group and the double distilled water DDW control group. Scanning electron microscopy (SEM) and infrared spectrometer (IR) were used. The surface characteristics of enamel sections in the mineralized solution treated group and the control group were examined. [results] the surface of enamel slices treated with mineralized solution was observed by scanning electron microscope. The surface of enamel was analyzed by X-ray diffractometer. The deposited hydroxyapatite crystals show that, Compared with the zinc ion group or the control group, the grain size, crystal integrity and deposition amount of the mineralized solution increased. Infrared spectrometer analysis of enamel surface treated with fluorine ion group and zinc, fluorine group mineralized solution showed that there were several P-O absorption peaks at 1102 ~ 1065 ~ 1027 cm-1. [conclusion] calcium ion, phosphate ion are present in the enamel surface, and the results show that there are many P-O absorption peaks at 1102 ~ 1065 ~ 1027 cm-1. [conclusion] there are calcium ions and phosphate ions in the enamel surface. Zinc ion and fluoride ion mineralized solution can form protective zinc-loaded fluoroapatite crystal layer on enamel surface, which can prevent and cure early enamel caries.
