【摘要】：目的:評(píng)估6種LED固化燈光照射強(qiáng)度隨光源距離的增加出現(xiàn)衰減的程度。方法:選擇6種LED光固化燈:配置標(biāo)準(zhǔn)光導(dǎo)棒的Bluephase、Bluephase C8和Elipar S10,配置聚光透鏡的Ascent PX,配置渦輪光導(dǎo)棒的Demi和Ti-Lite GT-1500。使用光強(qiáng)測(cè)量?jī)x在距光源0、1、2、3、4、5 mm測(cè)量光固化燈的光照射強(qiáng)度,每一距離測(cè)量10次,并計(jì)算光強(qiáng)度平均值及相應(yīng)的光強(qiáng)度衰減率。結(jié)果:6種固化燈初始光強(qiáng)度分別為859 m W/cm2(Bluephase C8)、1 121 m W/cm2(Bluephase)、1 133 m W/cm2(Elipar S10)、1 300 m W/cm2(Ascent PX)、1 497 m W/cm2(Demi)和1 192 m W/cm2(Ti-Lite)。除Ascent PX的1~3 mm光源距離外,光源距離每增加1 mm,6種固化燈的光照射強(qiáng)度均出現(xiàn)顯著降低(P0.05)。距離光源5 mm時(shí),只有Bluephase、Elipar S10和Ascent PX的光強(qiáng)度超過了400 m W/cm2,光強(qiáng)度衰減率分別為56.7%、58.7%、53.8%,明顯低于Bluephase C8(66%)、Demi(78.8%)和Ti-Lite(72.2%)。結(jié)論:臨床中應(yīng)盡可能選用高強(qiáng)度LED固化燈并延長(zhǎng)照射時(shí)間以彌補(bǔ)光源距離增加所造成的光強(qiáng)度衰減,建議選擇配置標(biāo)準(zhǔn)光導(dǎo)棒或聚光透鏡的高強(qiáng)度LED光固化燈。
[Abstract]:Aim: to evaluate the attenuation of LED curing light intensity with the increase of light source distance. Methods: six LED light-cured lamps were selected: Bluephase Bluephase C8 and Elipar S10 with standard light guide rod, Ascent PX with condensing lens, Demi and Ti-Lite GT-1500 with turbo guide rod. The light intensity of the light curing lamp was measured by using a light intensity meter at a distance of 0 ~ 1 ~ 2 ~ 3 ~ 3 ~ 4 ~ 5 mm from the light source. The light intensity was measured 10 times per distance, and the average light intensity and the corresponding attenuation rate of the light intensity were calculated. Results the initial light intensities of the six kinds of curing lamps were 859m W/cm2(Bluephase / c8121mW / cm2 and 1 133m W/cm2(Elipar S10 / 1 300m W/cm2(Ascent / cm ~ (2 +) and 1 192mW / cm ~ (2) Ti-Lite, respectively. With the exception of 1mm light source distance of Ascent PX, the light irradiation intensity of each light source increased by 1 mm and 6 kinds of curing lamps decreased significantly (P 0.05). When the light source is 5 mm away, only the optical intensity of Bluephase Elipar S10 and Ascent PX exceed 400m W / cm ~ 2, and the attenuation rate of optical intensity is 56.7 and 58.7, respectively, which is obviously lower than that of Bluephase C8666 and Demi ~ (78.8) and Ti-Lite 72.2. Conclusion: the high intensity LED curing lamp should be selected as far as possible in clinic and the irradiation time should be prolonged to compensate for the light intensity attenuation caused by the increase of the light source distance. It is suggested that the high intensity LED light solidified lamp with standard light guide rod or condenser lens should be selected.
