【摘要】：目的:隨著經(jīng)濟(jì)發(fā)展和物質(zhì)文化需求的提高,人們更加視身體健康和形象良好,越來越多的人不僅僅希望有一個健康的身體,還希望有一個完美的微笑。牙齒的顏色在微笑面容中是一個很重要的部分。牙齒顏色過深,牙齒著色,牙齒變色,以及發(fā)育性、藥物性牙齒顏色不良在臨床中十分常見,每個年齡組人群均可發(fā)生。根據(jù)變色原因的不同分為:外源性著色、內(nèi)源性著色,臨床中有很多方法改善牙齒著色。其中,活髓牙美白分為三種方法:診室內(nèi)美白、家庭美白以及非處方美白藥物。診室內(nèi)美白是在牙面涂布含有高濃度過氧化氫(15%～40%)的美白劑,一次治療后可取得較為明顯的效果。這種牙齒美白方法具有美白效果良好、安全性高和對牙齒無不可逆性損傷等優(yōu)點,因此被廣泛應(yīng)用于臨床。本研究旨在評價兩種臨床中廣泛應(yīng)用的美白藥物,Beyond冷光美白與OpalescenceBoost美白(即常用的普洋冷光美白和皓齒美白),評價牙齒的美白效果及美白持久性,以及在美白過程中和完成后,牙齒敏感性有無差異。材料方法:根據(jù)實驗?zāi)康闹贫▏?yán)格的志愿者納入標(biāo)準(zhǔn),并按照此標(biāo)準(zhǔn)篩選志愿者。將18名受試者納入本實驗研究,將每一名志愿者上下領(lǐng)從左側(cè)第一前磨牙到右側(cè)第一前磨牙選定為實驗牙齒,并從中線處分為左右兩側(cè),兩側(cè)隨機(jī)分別使用Beyond冷光美白系統(tǒng)與OpalescenceBoost美白系統(tǒng)。在進(jìn)行美白前進(jìn)行基線確定:使用Vita Easyshade電腦比色儀、和微距相機(jī)采集相片并使用軟件進(jìn)行色彩分析,測量并記錄每位志愿者16顆受試牙中央部位a*值、b值*、L*值,根據(jù)公式計算牙齒美白前后的△E值。比較Beyond冷光美白系統(tǒng)與OpalescenceBoost美白系統(tǒng)是否具有確切的美白效果、二者美白效果的差異、美白效果的持久性。同時調(diào)查志愿者美白術(shù)中及美白后牙齒敏感情況,對美白效果的滿意度。最后對研究數(shù)據(jù)進(jìn)行統(tǒng)計學(xué)處理(SPSS22.0),并分析得出結(jié)論。結(jié)果:1、Beyond冷光美白系統(tǒng)與OpalescenceBoost美白系統(tǒng)在美白后牙齒的明度(L*)、白度(b*)具有明顯提高,同時△E≥2.75,p值均小于0.05,說明二者具有確切的美白效果。2、Beyond冷光美白系統(tǒng)與OpalescenceBoost美白系統(tǒng)在美白后、48小時、一周、一月、三月各個時間點內(nèi),美白效果沒有明顯差異,p值均大于等于0.05,說明二者美白效果隨時間推移沒有表現(xiàn)出差異。3、Beyond冷光美白系統(tǒng)與OpalescenceBoost美白系統(tǒng)在美白后、48小時、1周、一月、三月美白效果都沒有明顯變化,P0.05,表明二者美白效果持續(xù)性較好。4、83.3%的志愿者出現(xiàn)可忍受牙齒敏感,并在48小時內(nèi)敏感可大部分自愈。5、88.9%志愿者對于美白效果滿意,44.4%的志愿者在美白完成時能主觀觀察到實驗兩側(cè)牙齒有輕微顏色差異(Beyond冷光美白系統(tǒng)略白于OpalescenceBoost美白系統(tǒng)),但此輕微差異會在48小時內(nèi)消失。結(jié)論:1、診室美白后,牙齒美白效果明顯,明度變高,黃度減少;美白效果持久性高。2、兩種美白產(chǎn)品在3個月內(nèi)的美白效果均表現(xiàn)為:確切有效,持續(xù)可靠,左右兩側(cè)顏色對稱,無明顯差異。3、兩種美白劑引起的牙齒輕微敏感可以被接受,Beyond美白劑與OpalescenceBoost美白劑同一個體敏感性無明顯差異,敏感性高低取決于受試者個體因素。臨床醫(yī)師在選擇美白劑時,應(yīng)先充分考慮患者的個體的敏感性。4、綜合考慮兩種美白產(chǎn)品的時間和經(jīng)濟(jì)成本,可以為患者選擇出更適合的美白產(chǎn)品。
[Abstract]:Objective: with the development of economy and improvement of material and cultural needs, people more visual health and good image, more and more people just want to have a healthy body, but also want to have a perfect smile. The color of the teeth is a very important part in the smiling face. The tooth color is too deep, teeth coloring, tooth discoloration, and the development of drug-induced adverse, tooth color is very common in clinical practice, each age group can occur. According to the different reasons for discoloration: exogenous endogenous coloring, coloring, there are many ways to improve clinical stain teeth. The teeth whitening is divided into three methods: consulting room in whitening, whitening family and non prescription drugs. Consulting room whitening whitening is containing a high concentration of hydrogen peroxide in the tooth surface coating (15% ~ 40%) whitening agent, after one treatment can obtain obvious effect. This kind of tooth Whitening whitening method has good effect, high safety and no teeth reversible injury etc, so it is widely used in clinic. The purpose of this study is to evaluate the two kinds of whitening agents are widely used in clinical medicine, Beyond whitening whitening and OpalescenceBoost (that is commonly used in whitening teeth whitening and Pu Yang), evaluation of tooth whitening the effect of whitening and persistence, and the completion of the whitening process after neutralization, there is no difference of tooth sensitivity. Materials and methods: according to the strict criteria of volunteers, and in accordance with the standard screening volunteers. The study included 18 subjects, each volunteer on the collar from the left side of the first to the right side of the first premolar molar teeth were selected for the experiment, and the left and right sides from the center line on both sides of random disposition, respectively using Beyond tooth whitening system with OpalescenceBoost whitening system. For baseline determined using Vita Easyshade computer colorimeter, and macro camera photos and use software for color analysis, measure and record each volunteer 16 specimens the central part of the a* value, b value, L* value, according to the formula of tooth whitening value before and after E. Beyond whitening the system and whether the system has exactly OpalescenceBoost whitening whitening effect, the difference between the two whitening effect, lasting whitening effect. At the same time survey volunteers during and after tooth whitening whitening whitening effect on the sensitive situation, the degree of satisfaction. Finally the research of statistical data processing (SPSS22.0), and analyze the conclusion. Results: 1 Beyond, whitening and OpalescenceBoost tooth whitening system in after whitening the lightness (L*), white (b*) has increased significantly, while the E = 2.75, P values were less than 0.05, indicating that two is indeed Cut the whitening effect of.2, Beyond whitening system and OpalescenceBoost system in whitening whitening after 48 hours a week, January, March each time point, there was no significant difference between whitening effect, P value was greater than or equal to 0.05, indicating the two whitening effect over time showed no difference between.3, Beyond and tooth whitening system OpalescenceBoost whitening whitening system in after 48 hours, 1 week, January March, whitening effect did not change significantly, P0.05, indicating that the two whitening effect good continuity.4,83.3% volunteers appeared tolerable sensitive teeth, and in 48 hours can be most sensitive.5,88.9% volunteers for self-healing whitening effect with 44.4% volunteers to subjective observation the teeth on both sides of a slight color difference in complete whitening (system slightly white Beyond whitening whitening system on OpalescenceBoost), but this slight difference within 48 hours Disappeared. Conclusion: 1. Consulting room whitening, teeth whitening effect, high lightness, yellowness decreased; the whitening effect of persistent high.2, whitening effect of two kinds of whitening products within 3 months are as follows: the effective, reliable and continuous, the left and right sides of the color symmetry, there was no significant difference in.3, two tooth whitening agent caused by the slight sensitive can be accepted, Beyond whitening agent and OpalescenceBoost whitening agent of the same individual sensitivity had no significant difference in the sensitivity depends on the subjects' individual factors. Clinicians in the selection of whitening agent, should fully consider the sensitivity of.4 of individual patients, considering two kinds of whitening products and time the economic cost, can choose more suitable whitening products for patients.
