To assess orthodontic clinicians' knowledge and attitudes towards dentogingival aesthetics and to explore characteristics that predict the knowledge of dentogingival aesthetics.
Cross-sectional questionnaire.
On-line survey of members of the British Orthdontic Society.
An 11-item online questionnaire was sent to orthodontic practitioners for completion. The questionnaire covered respondent demographics and questions relating to both knowledge and attitudes towards dentogingival aesthetics (six parameters). Descriptive statistics were calculated for study characteristics and summary values for the survey items. Responses to the eight knowledge-based questions were converted to a binary outcome (correct and incorrect answer). The maximum score that could be achieved was eight. Multivariable modelling was used in order to examine associations between the study characteristics and the aggregate score.
A total of 252 responses were obtained resulting in a response rate of 17%. Within this cohort, the respondents were primarily women (52.8%) and aged 30-40 years (35.7%). The mean score for the eight knowledge-based questions was 3.8 ± 1.8 (range = 0-8). Knowledge of the ideal gingival margin position of the anterior teeth was high (92.4%). Knowledge of the other five dentogingival aesthetic parameters was variable. In the multivariable analysis, lower knowledge scores were predicated by respondents who did not have a special interest in dental aesthetics (-0.54; 95% confidence interval [CI] = -1.01 to -0.07; = 0.02), who could not recall attending courses, lectures or seminars on dental aesthetics in the past five years (-0.80; 95% CI = -1.43 to -0.17; = 0.01) and with increasing age (-0.43; 95% CI = -0.62 to -0.23; < 0.001).
Knowledge of ideal dentogingival parameters is generally suboptimal among orthodontists in the UK. The reported lack of knowledge of the ideal dentogingival parameters may also influence respondents' attitudes towards the importance of dentogingival aesthetics. Further teaching or courses related to dentogingival aesthetics is desired by orthodontic clinicians.
评估正畸临床医生对牙龈美学的知识和态度，并探讨预测牙龈美学知识的特征。
横断面问卷调查。
英国正畸学会成员的在线调查。
向正畸医生发送了一份 11 项在线问卷进行完成。问卷涵盖了受访者的人口统计学特征以及与牙龈美学（六个参数）相关的知识和态度问题。计算了研究特征的描述性统计数据和调查项目的汇总值。将八道基于知识的问题的答案转换为二进制结果（正确和错误答案）。可以达到的最高得分为 8 分。使用多变量模型来检查研究特征与总分之间的关联。
共获得 252 份回复，回复率为 17%。在这一组中，受访者主要是女性（52.8%）和 30-40 岁（35.7%）。八道基于知识的问题的平均得分为 3.8±1.8（范围为 0-8）。对前牙理想牙龈边缘位置的知识较高（92.4%）。对其他五个牙龈美学参数的知识则有所不同。在多变量分析中，知识得分较低的预测因素包括对牙科美学没有特殊兴趣的受访者（-0.54；95%置信区间 [CI] = -1.01 至 -0.07； = 0.02）、在过去五年内无法回忆起参加过牙科美学课程、讲座或研讨会的受访者（-0.80；95%CI = -1.43 至 -0.17； = 0.01）和年龄增长（-0.43；95%CI = -0.62 至 -0.23； ＜0.001）。
英国正畸医生对理想牙龈参数的知识普遍不足。报告中缺乏对理想牙龈参数的了解也可能影响受访者对牙龈美学重要性的态度。正畸医生希望进一步教授或提供与牙龈美学相关的课程。
