The authors conducted this study to assess the quality of the information available on the Web about oral hygiene for patients with fixed orthodontic appliances.
The authors entered the search terms "cleaning braces," "brushing braces," and "oral hygiene and braces" into Google, Yahoo, and Bing search engines. They analyzed Web sites satisfying the inclusion criteria from the first 20 hits of each search for accessibility, usability, and reliability by using the LIDA instrument; for readability by using the Flesch Reading Ease (FRE) score; and for the completeness of oral hygiene instructions.
Sixty-two Web sites met the inclusion criteria. The mean total LIDA score of 71.2 indicated the moderate quality of the design of the reviewed Web sites. The mean (standard deviation [SD]) values of LIDA scores for accessibility, usability, and reliability were 85.9 (7.0), 63.4 (16.1), and 48.0 (10.4), respectively. The mean (SD) FRE Score of 68.6 (9.7) applied to standard reading skills. The completeness of information (mean [SD] = 67.1 [27.8]) presented the highest variability.
Overall, the authors found that the standards of online oral hygiene materials for orthodontic patients with fixed appliances exhibited modest scores. Readability appeared to be appropriate for young adolescents, whereas the comprehensiveness of the displayed information was highly variable. Further improvement of the infrastructure of electronic health information (that is, e-health) in orthodontics is necessary to meet patients' needs.
Given the moderate quality of oral hygiene instruction available on the Web for patients with fixed appliances, orthodontic patients and caregivers should be cautious when browsing the Internet for relevant information. Dental professionals should refer patients to valid Web-based educational materials.
作者开展本研究以评估网络上有关固定正畸矫治器患者口腔卫生的可用信息质量。
作者在谷歌、雅虎和必应搜索引擎中输入搜索词“清洁牙套”“刷牙套”以及“口腔卫生与牙套”。他们使用LIDA工具分析每个搜索结果前20条中符合纳入标准的网站的可及性、可用性和可靠性；使用弗莱什易读性（FRE）分数分析可读性；并分析口腔卫生指导的完整性。
62个网站符合纳入标准。LIDA总分平均分为71.2，表明所审查网站的设计质量中等。可及性、可用性和可靠性的LIDA分数均值（标准差[SD]）分别为85.9（7.0）、63.4（16.1）和48.0（10.4）。适用于标准阅读技能的FRE分数均值（SD）为68.6（9.7）。信息完整性（均值[SD]=67.1[27.8]）的变异性最高。
总体而言，作者发现针对固定矫治器正畸患者的在线口腔卫生材料标准得分一般。可读性似乎适合青少年，而所展示信息的全面性差异很大。正畸领域电子健康信息（即电子健康）基础设施的进一步改善对于满足患者需求是必要的。
鉴于网络上针对固定矫治器患者的口腔卫生指导质量一般，正畸患者及其护理人员在浏览互联网获取相关信息时应谨慎。牙科专业人员应向患者推荐有效的基于网络的教育材料。
