1、乳飲料對(duì)年輕恒牙脫礦作用的研究1.天津醫(yī)科大學(xué)總醫(yī)院天津300052；2.天津醫(yī)科大學(xué)總醫(yī)院口腔內(nèi)科天津300052【摘要】目的：研究目前市場(chǎng)暢銷(xiāo)的乳飲料對(duì)年輕恒牙釉質(zhì)的脫礦作用，比較不同飲料對(duì)牙釉質(zhì)的脫礦程度。方法：將顯微鏡下觀察無(wú)齲、無(wú)裂紋及釉質(zhì)發(fā)育缺陷的42個(gè)釉質(zhì)樣木，隨機(jī)分成四組：A為每日活菌組，B為沙棘酸牛奶組，C為酸牛奶組，每組12個(gè)樣木，D為對(duì)照組，含6個(gè)樣木；四組牙釉質(zhì)塊均用相同人工唾液儲(chǔ)存于同一條件下。將每組樣木經(jīng)過(guò)不同的飲料及不同的方法處理后通過(guò)能譜分析儀及掃描電鏡分析其表面形態(tài)及鈣磷含量的變化并用SPSS19
2、.0分析。結(jié)果：三種乳制品飲料都會(huì)導(dǎo)致釉質(zhì)的脫礦。經(jīng)去離子水沖洗后的牙釉質(zhì)較未經(jīng)去離子水沖洗的牙釉質(zhì)脫礦程度低。結(jié)論：不同的乳飲料均會(huì)導(dǎo)致牙釉質(zhì)脫礦，但其脫礦程度略有差別。提醒廣大青少年合理飲用乳制品飲料，同時(shí)建議飲用飲料后及時(shí)漱U,以預(yù)防或減少其對(duì)牙釉質(zhì)的脫礦作用，降低牙齒的患齲率?！娟P(guān)鍵詞】乳飲料，年輕恒牙，脫礦AnexpelrimentalstudyonyoungpermanentteethenameldeminerlaziationbymilkdrinksBaiXiangyu，ZhangJieTianjinMedicalU
