[摘要] 目的 探討正畸后白堊斑采用滲透樹(shù)脂治療的療效。 方法 選取2014年8月～2015年8月期間我院接收的正畸后白堊斑患者24例，將入選者隨機(jī)分為涂氟處理組（n=12，共45顆牙齒）與滲透樹(shù)脂組（n=12，共45顆牙齒），涂氟處理組采取涂氟處理治療，滲透樹(shù)脂組采取滲透樹(shù)脂治療，觀察兩組的美學(xué)效果。 結(jié)果 兩組治療后1周、治療后3個(gè)月時(shí)的R值較治療前均顯著減小（P<0.05），治療后3個(gè)月時(shí)R值較治療1周時(shí)有所降低，但無(wú)明顯差異（P>0.05），不同時(shí)間點(diǎn)R值比較，滲透樹(shù)脂組顯著低于涂氟處理組（P<0.05）；兩組治療后3個(gè)月的SR值較治療后1周有所升高，但無(wú)明顯差異性（P>0.05），在不同時(shí)間點(diǎn)滲透樹(shù)脂組的SR值較涂氟處理組顯著要高（P<0.05）。 結(jié)論 滲透性樹(shù)脂治療正畸后白堊斑，相對(duì)于涂氟處理，可更大程度地減少病損面積，使牙外觀改善，且短期內(nèi)效果穩(wěn)定，具有推廣價(jià)值。

[Abstract] Objective To investigate the effect of penetrating resin in the treatment of chalk spot after orthodontic treatment. Methods A total of 24 patients with post-orthodontic chalk spot admitted in our hospital from August 2014 to August 2015 were randomly divided into group A（n=12， with 45 teeth） and penetrating resin group（n=12， with 45 teeth）. The fluoride treatment group was given fluoride treatment， and the penetrating resin group was given the penetration resin treatment. The aesthetic effect between the two groups was observed. Results The R values in the two groups at one week and 3 months after treatment were significantly lower than those before treatment（P<0.05）. The R value at 3 months after treatment was lower than that at one week after treatment， but there was no significant difference（P>0.05）. R values at different time points were compared， and the R value of the penetrating resin group was significantly lower than that of the fluoride treatment group（P<0.05）. The SR values in the two groups at 3 months after treatment were higher than those at one week after treatment， but there was no significant difference（P>0.05）. The SR value of the penetrating resin group was significantly higher than that of the fluoride treatment group at different time points（P<0.05）. Conclusion Penetrating resin in the treatment of chalk spot after orthodontics can reduce the lesion area to a greater extent compared with fluoride treatment， and can improve the appearance of teeth， with stable short-term effect and promotion value.

釉質(zhì)白堊斑是由各種病因?qū)е碌挠再|(zhì)脫礦，其內(nèi)部形成大量的微孔樣結(jié)構(gòu)，牙齒表面呈白堊色，是口腔臨床常見(jiàn)的釉質(zhì)表面病損。研究顯示，正畸患者治療后白堊斑的發(fā)生率為46.5%，其中前牙白堊斑的發(fā)生率為23.4%。在正畸過(guò)程中，由于帶環(huán)、托槽、弓絲等矯治器的存在，使牙齒清潔的難度大大增加，再加上正畸患者多為青少年，對(duì)口腔衛(wèi)生重視度不夠，常導(dǎo)致牙面白堊斑的出現(xiàn)[1-2]。若不治療，其可進(jìn)一步發(fā)展為釉質(zhì)齲。涂氟處理與滲透性樹(shù)脂是臨床治療正畸后白堊斑的主要手段，但究竟哪個(gè)療效更優(yōu)目前鮮有研究報(bào)道。為此，本研究通過(guò)對(duì)2014年8月～2015年8月期間我院接收的24例正畸后白堊斑患者資料進(jìn)行回顧性分析，探討氟處理與滲透樹(shù)脂對(duì)正畸后釉質(zhì)白堊斑的治療療效，現(xiàn)報(bào)道如下。
