[摘要] 目的 探討口腔正畸固定矯正治療中發(fā)生牙釉質(zhì)脫落的情況,并就如何防止牙釉質(zhì)脫落展開分析。 方法 回顧性分析2015年2月—2017年2月期間在該院接受口腔正畸固定矯正治療的120例患者臨床資料,矯正期結(jié)束后拆除固定矯治器,借助牙科治療臺(tái)燈光觀察患者牙釉質(zhì)脫落情況。觀察120例患者治療后牙釉質(zhì)脫落情況,分析導(dǎo)致患者牙釉質(zhì)脫落的原因。結(jié)果 120例患者中有34例出現(xiàn)不同程度的牙釉質(zhì)脫落情況,發(fā)生率為28.33%。從上下頜發(fā)生率來看,上頜脫礦率18.90%顯著高于下頜脫礦率7.62%,差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。經(jīng)logistic回歸分析發(fā)現(xiàn),口腔衛(wèi)生、牙面酸蝕、齦下菌斑、年齡等原因是導(dǎo)致牙釉質(zhì)脫礦的危險(xiǎn)因素。結(jié)論 口腔正畸固定矯正治療受到多種因素共同作用可導(dǎo)致牙釉質(zhì)脫礦,加強(qiáng)口腔健康知識(shí)宣傳、強(qiáng)化斑菌控制意識(shí)、指導(dǎo)患者正確的舒雅方式,養(yǎng)成良好的進(jìn)食習(xí)慣能有效預(yù)防牙釉質(zhì)脫礦。

[Abstract] Objective This paper tries to investigate the occurrence of enamel shedding in oral orthodontic treatment and to analyze how to prevent the enamel shedding. Methods The clinical data of 120 patients from February 2015 to February 2017 in this hospital for oral orthodontic treatment were retrospectively analyzed; the end of the correction period after the removal of fixed appliance, with dental treatment desk to observe the patients enamel shedding and the causes of enamel shedding. Results 34 cases of 120 cases of varying degrees of enamel shedding occurred, the incidence was 28.33%. The maxillary prolapse rate was 18.90%, higher than that of mandibular degeneration rate of 7.62%, and the difference was statistically significant(P<0.05). Logistic regression analysis showed that oral hygiene, tooth surface erosion, subgingival plaque, age and other reasons were leading to demineralization of enamel risk factors. Conclusion Oral orthodontic treatment can lead to enamel demineralization, strengthen oral health knowledge, strengthen the awareness of bacteria control, and guide the correct way of clearing the teeth, and develop good eating habits, which can effectively prevent enamel demineralization.

口腔正畸是通過口腔技術(shù)手段,將排列不齊的牙齒進(jìn)行矯正,矯正的方法有很多,最常見的就是固定矯正器治療。固定矯正器治療具有高精度、療效好的優(yōu)勢(shì),是很多臨床醫(yī)師和患者們的首選,在近百年來受到廣泛關(guān)注。但在口腔正畸固定矯正治療過程中,牙釉質(zhì)脫礦等并發(fā)癥是比較常見的問題,發(fā)生牙釉質(zhì)脫礦可能造成患者牙齒損傷,破壞口腔環(huán)境,危害極大,因此如何預(yù)防牙釉質(zhì)脫礦也成為人們關(guān)注的焦點(diǎn)[1]。該次研究以該院2015年2月—2017年2月期間進(jìn)行口腔正畸固定矯正治療的120例患者為例,探討口腔正畸固定矯正治療中發(fā)生牙釉質(zhì)脫落的情況,并就如何防止牙釉質(zhì)脫落展開分析,現(xiàn)報(bào)道如下。
