ABSTRACT
Objective 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.
ABSTRACT
Objective To explore the influential factors of esthetic evaluation of mandibular prominence by orthodontic patients from two dimensions (ideal value and tolerance range).Methods 226 orthodontic patients were investigated by an electronic questionnaire of esthetic evaluation of mandibular prominence.Binary logistic regression was adopted to analyze the influential factors.Results The tolerable boundary value for female mandibular retrognathism was affected by age (OR1.360) and orthodontic history (OR2.849).The tolerable boundary value for female mandibular prognathism and male mandibular retrognathism were found to be affected by orthodontic history (OR2.557 and 2.845,respectively).The tolerable boundary value for male mandibular prognathism was affected by age (OR1.347) and orthodontic history (OR2.310).The ideal value of male mandibular prominence was affected by age (OR1.420).Conclusions Orthodontic patients' esthetic evaluation of mandibular prominence is influenced by age and treatment condition,but not by sex,education level,marital status and personal profile.
ABSTRACT
Objective To investigate the factors influencing positive and negative affects ot orthodontic patients.Methods 145 orthodontic patients were selected and finished questionnaire survey.The questionnaires included demographic data,psychosocial impact of dental aesthetic questionnaire (PIDAQ),aesthetic content of index of orthodontic treatment need (IOTN-AC),perception of occlusion scale (POS),and positive affect and negative affect scale (PANAS).Mann-Whitney U-test,Kruskal-Walis H-test,and Spearman correlation analysis were used to analyze the relation between impact of dental aesthetics and positive and negative affects in orthodontic patients.Results The scores of adolescent patients were higher than adult patients in negative affect (U =1886.500,P＜0.05).The patients under orthodontic treatment scored higher than those before treatment (U=2228.000,P＜0.05).The subdomains of PIDAQ,such as social impact (x2=ll.794,P＜0.05),aesthetic attitude (x2 =45.853,P＜0.05),and dental confidence (x2 =33.551,P＜0.05) were related with negative affect.The scores of IOTN-AC,PIDAQ,POS demonstrated positive correlation with negative affect (P＜0.05).The scores of social impact showed negative correlation with positive affect (P＜0.05).Conclusions Adult orthodontic patients suffer more negative affect than adolescent patients.Orthodontic treatment could promote patients' positive affect.However,the negative psychosocial impact in dental aesthetics would strengthen the negative affect.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the most acceptable lower anterior face height of male and female by orthodontic treatment seeking people.</p><p><b>METHODS</b>Two hundred and thirty-two Chinese orthodontic seeking people of Guanghua Hospital of Stomatology of Sun Yat-sen University were randomly selected in this survey. An electronic questionnaire was designed with a set of male and female young Chinese adult images with changes of the lower anterior face height (while the middle anterior face height remains the same). They were asked about the lowest, highest and optimal proportion (or so-called lower, higher and optimum limits respectively) between the lower anterior face height and the middle anterior face height (LAFH/MAFH) they could accept. All the findings of the proportion were analyzed by a statistic system.</p><p><b>RESULTS</b>The lower limits' median value in regard to the LAFH/MAFH of male model and female model images was 0.8, this limit value for the male model's was greater than the female model's (P = 0.039); the higher limits' median value was 1.1, this limit value for the male model's was less than the female model's (P < 0.001); the optimum limits' median value was 0.9, this limit value for the male model's was greater than the female model's (P < 0.001).</p><p><b>CONCLUSION</b>The result of this study shows all lower, higher and optimal limits accepted by the orthodontic treatment seeking people in regard to the proportion between the lower and middle height of anterior faces. This result will facilitate the understanding of aesthetic judgments of orthodontic patients on profile lower anterior facial height for orthodontist in treatments.</p>

Objective To explore the related factors that might had effect on orthodontic patients' esthetic evaluation of axial dental midline angulation from three aspects which are ideal value,detectable value and tolerable value.Methods Photographs of a smiling woman was digitally manipulated to produce models with left or right maxillary axial dental midline angulations in 2° increments.These digital photographs models were used to develop an electronic questionnaire in combination with corresponding guidance for each question.The electronic questionnaire was applied to investigate the esthetic evaluation of axial dental midline angulation from 222 orthodontic patients who complied with the inclusion criteria.Esthetic evaluation included three aspects,the ideal value,the detectable value and the tolerable value,which represented the degrees of maxillary axial dental midline angulations the patients considered to be ideal,detectable and tolerable,respectively.The patients' personal information and clinical orthodontic examination results were collected as well.Results The mean detectable value and tolerable value were 4.9° and 9.7°,the median of detectable value and tolerable value were 5°and 9.5°.Logistic regression analysis was applied to explore the influence of seven factors on each evaluator's ideal value,detectable value and tolerable value.The seven factors were gender,marriage condition,education level,orthodontic treatment condition,malocclusion index,dental esthetic rating from others and from themselves.The statistical analysis indicated education level and orthodontic treatment condition were the influential factors of detectable values,while the tolerable values were influenced by the education level and gender.The ideal value converged to 0° and none of the factors had effect on it.Conclusions The education level,orthodontic treatment condition and gender are considered to be the influential factors of the esthetic evaluation of axial dental midline angulation.
ABSTRACT
Objective To translate the original English version of psychosocial impact of dental aesthetics questionnaire (PIDAQ) into Chinese version and to test the psychometric properties of the Chinese version for use among the Chinese young adults. Methods In accordance with standard procedures of international quality of life assessment project, the original English version of PIDAQ was translated into Chinese, pre-tested and cross-cultural adapted. Subsequently the Chinese version and two other scales, aesthetic component of the index of orthodontic treatment need (IOTN-AC) and perception of occlusion scale (POS), were administered to young adults, 140 of which were orthodontic patients on the first visit, and 296 were general residents without orthodontic treatment in Guangzhou.Reliability and validity of the translated scale were assessed. Results Cronbachs α of the translated scale was 0. 942, standardized Cronbachs α was 0. 943, corrected item-total correlation ranged from 0. 392 to 0. 812. PIDAQ and its 3 dimensions were significantly associated with IOTN-AC and POS.Conclusion The translated Chinese version of PIDAQ demonstrates good reliability and validity. Its good psychometric properties provide the theoretical evidence for further use in Chinese young adults.
