摘要/Abstract

摘要：

目的:使用Smile Lite MDP(Smile Lite Mobile Dental Photograph)便携式口腔摄影系统进行前牙美学摄影的应用探索,简化美学摄影,方便医患沟通以及医技交流。方法:使用Smile Lite MDP摄影系统配合智能手机拍摄前牙正面咬合相,对色温参数设置、Smile Lite MDP灯光组合及灯光强度等拍摄条件进行探索,采用医师及技师盲法评价的问卷调查方式,以视觉模拟评分法量表(visual analogue scale/score, VAS)评估最佳拍摄参数。使用Smile Lite MDP摄影系统在最佳拍摄条件下拍摄口内正面咬合相,分别测量中切牙正面观宽长比以及上前牙正面观宽度比,以数码单反相机拍摄的照片作为对照标准,研究Smile Lite MDP摄影系统对前牙形态还原的准确度。结果:Smile Lite MDP便携摄影系统成像的最佳色彩还原的色温参数为5 000 K,最佳变焦倍数为4倍,Smile Lite MDP两侧灯光开启,灯光强度2档,采用该组条件的拍摄效果VAS评分较高,与其他组相比差异有统计学意义(P<0.05)。Smile Lite MDP便携摄影系统使用4倍放大率拍摄和单反相机拍照系统摄影标准参数拍摄上前牙的比例差异无统计学意义(P>0.05)。结论:Smile Lite MDP便携式口腔摄影系统应用于前牙美学分析摄影中能够真实、准确地还原前牙的颜色和形态,可以作为临床工作中简便易行的摄影工具。

Abstract:

Objective: To explore the possibility of the Smile Lite MDP (Smile Lite Mobile Dental Photograph) portable dental photography system applying in anterior teeth aesthetic photography, and to provide the chance to simplify aesthetic photography process and facilitate communication among patients, dentists and dental technitians. Methods: The Smile Lite MDP photography system combined with the smartphone were used to photograph the front occlusal phase photos of anterior teeth. The photographic conditions including the color temperature parameter, the Smile Lite MDP light position and the intensity settings were explored. The best photographic conditions were chosen by blind evaluation within expe-rienced dentists and technicians through the method of the visual analogue scale/score (VAS) evaluation, which went through statistical analysis to figure out the optimum photograghic conditions. Smile Lite MDP photography system was used to photograph the front occlusal phase photos of anterior teeth under the optimum parameter by different magnifications. The width/height ratio of the central incisor and the front width ratio of the upper anterior teeth in those photos were measured and calculated respectively. The accuracy of the anterior teeth photos taken by Smile Lite MDP photography system was analyzed based on the photographs taken by digital single lens reflex (DSLR) camera. Results: The optimum color temperature parameter of Smile Lite MDP portable camera system was 5 000 K, the optimum magnification was 4 times, the best light position was the side lights of Smile Lite MDP, the optimum intensity of lights was 2 grades. Photos taken by the optimum parameters won the highest score during the VAS evaluation and the result of statistical analysis had significant difference compared with other groups (P<0.05). When comparing the photos of the upper anterior teeth taken by the Smile Lite MDP portable photography system using 4 times magnification or by DSLR using the standard parameters, there was no significant difference neither in the width/hieght ratio of the central incisor nor in the front width ratio of the upper anterior teeth (P>0.05). Conclusion: The Smile Lite MDP portable dental photography system applying in anterior teeth aesthetic analysis photography was capable to show the color and shape of anterior teeth in an accurate way by using the right photography parameters. Therefore, Smile Lite MDP portable dental photography system was considered to be a simple and easy photographic tool in clinical work.
