| Abstract |
Background/Objectives:To collect the reference values for facial asymmetry in adults using landmark and surface-based three-dimensional analyses and to compare their diagnostic abilities.Materials and Methods:Laser scans were taken from 85 British Caucasians, 29 males (23.9±5.7 years, range 19-44) and 56 females (28.1±9.5 years, range 19-54), students and staff of the Cardiff Dental Hospital, and three orthodontic patients with marked facial asymmetry. An asymmetry index (AI) was measured for 14 landmarks. The surface-to-surface average distance between the best-fit registered original and mirror scans (ADom) was measured for the whole face and six regions. Non-parametric descriptive statistics was used to obtain the reference values, and Mann-Whitney U-test was used for gender comparison. P values less than 0.05 were considered significant. Patients' values were compared to the reference values by calculating the corresponding percentiles.Results:The lowest AI was found for 'pronasale' in males [median 0.1 (interquartile range 0.0-0.3) mm] and the highest for 'cheilion' [3.5 (2.4-5.0) mm] in females. The ADom for the whole face was 0.7 (0.5-0.9) mm in males and 0.6 (0.5-0.7) mm in females and regionally between 0.4 (0.3-0.6) mm and 0.8 (0.4-1.2) mm. In orthodontic patients, AI did not always reveal asymmetry in a particular coordinate plane, and surface-based analysis was favourable in regions underrepresented by landmarks.Conclusions:Facial asymmetry can be accurately quantified using landmark- and surface-based approaches. The latter offers a more comprehensive analysis of the face. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 January 2015.
All research outputs
#18,351,676
of 22,727,570 outputs
Outputs from European Journal of Orthodontics
#617
of 846 outputs
Outputs of similar age
#157,964
of 212,101 outputs
Outputs of similar age from European Journal of Orthodontics
#5
of 9 outputs
Altmetric has tracked 22,727,570 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 846 research outputs from this source. They receive a mean Attention Score of 3.0. This one is in the 18th percentile – i.e., 18% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 212,101 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 4 of them.
