摘要目的 探讨正畸患者对自身侧貌突度的感知能力.方法 2016年5-8月,调查中山大学附属口腔医院正畸科就诊符合样本标准的226例患者(男79例,女147例,平均19.3岁)对自身侧貌的关注度.让患者从模板中选出与自身侧貌最接近图片,拍摄其侧貌像,比较患者感知的侧貌与其真实侧貌的差异.结果 226例中有147例患者表示注意过自己的侧貌,占65.0％;其中男41例(27.9％);女106例(72.1％),表示注意过自己的侧貌.男性患者感知侧貌与真实侧貌差异有统计学意义(P＜0.05).女性患者感知侧貌与真实侧貌的差异无统计学意义(P＞0.05).女性患者感知侧貌与真实侧貌差异较男性小.结论 正畸患者中,女性较男性更注重自身侧貌.女性对自身侧貌感知的准确度较男性高.

abstractsObjective To make a preliminary study on self-perception of profile among orthodontic patients.Methods A total of 226 orthodontics patients (79 males and 147 females with average age of 19.3 years) were enrolled in this study.All the patients were treated in the Department of Orthodontics,Sun Yat-sen University Hospital of Stomatology during May to August 2016.Self-perception of profile was investigated in the patients.They were asked whether they had ever noticed their own profile and to choose from among various photos the one that most resembled their own profile.Then profile photos of patients were taken and measured.Differences between self-perception profile and actual profile were compared using paired t test.Results There were 147 patients (41 males and 106 females) answered that they had noticed their own profile.Difference was significant between patients' actual profile and self-perception profile (P＜0.05).Difference was significant between male patients' actual profile and self-perception profile (P ＜0.05).Difference was not significant between female patients' actual profile and self-perception profile (P ＞ 0.05).Compared with male patients,difference was smaller between female patients' actual profile and self-perception profile.Conclusions Compared with male patients,female patients put more emphasis on their own profile.Patients' self-perception of their own profile is not accurate.Female patients' self-perception of their own profile is more accurate than male patients.
