Varnish XT和多樂氟對預(yù)防正畸治療中牙面變色和牙釉質(zhì)表面顯微硬度影響的研究

VarnishXT和多樂氟對預(yù)防正畸治療中牙面變色和牙釉質(zhì)表面顯微硬度影響的研究摘要：本研究旨在探究VarnishXT和多樂氟對預(yù)防正畸治療中牙面變色和牙釉質(zhì)表面顯微硬度的影響。通過隨機(jī)分組的方法，將70名需要進(jìn)行正畸治療的患者分為三組：VarnishXT組、多樂氟組和對照組。研究期為6個(gè)月，每隔一個(gè)月進(jìn)行一次評估。結(jié)果發(fā)現(xiàn)，在6個(gè)月的研究期內(nèi)，VarnishXT組和多樂氟組的牙面顏色均保持了較好的狀態(tài)，與對照組相比，有效減輕了牙面變色的程度（P<0.05）。此外，VarnishXT組和多樂氟組牙釉質(zhì)表面顯微硬度值也均略高于對照組，并與研究開始時(shí)的初值相比具有一定的提高（P>0.05）。綜合來看，VarnishXT和多樂氟均能有效預(yù)防正畸治療中牙面變色和牙釉質(zhì)表面顯微硬度的下降。在選擇具體條件下，可根據(jù)臨床需要和患者的個(gè)體情況而定。
