“…The soft tissue cephalometric analysis is widely employed in orthodontics to evaluate facial harmony and aesthetics. [ 7 8 9 ] This analysis uses several measurements, such as nasolabial angle (NLA) – formed by the lower base of the nose and by the upper lip,[ 10 ] the H-line – tangent to the most salient point of the chin and upper lip, and the H angle – formed by the intersection of the H-line with the NaPog line. [ 11 ] However, soft tissues may not always follow bone tissue morphology in an absolute ratio.…”

Objective:This study was aimed to evaluate the perception of orthodontists and of lay people about the facial profile and its possible correlation with cephalometrics parameters.Materials and Methods:A total of 20 evaluators were divided into two groups (10 orthodontists and 10 people with no relation to such area – lay people). They were asked to evaluate the photographs of 25 young males and of 25 young females, aged 17–24-year-old (mean age of 22.3 years, standard deviation 2.41 years). Photographs were randomly arranged in a photo album. The evaluators rated each photograph by means of a scale ranging from “good” to “deficient” based on the pleasantness of their facial profile. Nasolabial angle, Holdaway's H-line and the distance from H-line to nose tip were measured, in order to verify a possible relation between these soft tissue profile cephalometric measurements and the subjective ratings.Results:The kappa statistics test showed a concordance of 0.23 among orthodontists and 0.24 among lay people. Regarding the perception of orthodontists and lay people on facial profile, no significant divergence could be detected. For the correlation between cephalometric parameters and subjective ratings, there was a statistically significant correlation between the measures H and H-nose and the rating ascribed to the profile.Conclusions:It was concluded that smaller the difference from the normal cephalometric pattern, the higher was the rating given to the profile, demonstrating an important relation between subjective and objective criteria.

Objective:To analyze a possible correlation between different measures in the definition of vertical facial types.Materials and Methods:This is an analytical observational study about 95 lateral teleradiographs of Caucasian individuals with normal occlusion, of which 54 were male (56.84%) and 41 female (43.16%), aged between 15 years and 2 months old and 21 years and 4 months old. Facial types were divided into dolichofacial, mesofacial, and brachyfacial, according to the standards established by different authors. A relationship between these measurements was verified using total agreement analysis and the Kappa method, with the interpretation suggested by Landis and Koch.Results:Kappa was considered fair for Jarabak X VERT (0.22 and 60%) and slight for Jarabak X SN. GoGn (0.06 and 36.8%).Conclusions:Cephalometric studies often present different interpretations on the description of vertical facial types. In this study, the lowest agreement was between Jarabak and SN.GoGn. Such difference in interpretation may lead to distinct therapeutic approaches and thus different results.

“…With the advancements, various developments in the cephalograms have been proposed. [ 9 ] However, assessment of the soft tissues using frontal cephalogram radiographs alone is not possible. Various techniques in addition to conventional cephalogram have been used for assessing the changes in the soft tissues.…”

Background: Graber introduced facial photographs as an internal diagnostic aid. Facial photographs could serve as an important alternative assessment tool in the absence of equipment for cephalometric analysis. Objectives: The present study was aimed at assessing whether analyzing the photographs could have precision for assessing the landmarks appropriate for facial analysis. In addition, the relationship between frontal cephalogram and measurements on photographs was assessed. Materials and Methods: Twenty individuals including both males and females within the age range of 18 years to 28 years were enrolled in the study. Frontal facial photographs, as well as frontal cephalograms, were obtained for all the included study participants. Various soft-tissue vertical and horizontal landmarks were marked on both radiographs and photographs. The data were collected and subjected to statistical analysis. Results: The results showed a statistically insignificant difference between all the vertical and horizontal parameters on photographs and cephalograms. The reliability of the digital photographs was comparable to that of the cephalograms with nonsignificant differences in the recorded mean values using the one-way ANOVA test where the statistical significance level was kept at P ≤ 0.05. Conclusion: The present study concluded that photography is a cost-effective and reliable method for soft-tissue landmark identification, and allows recording the images of sufficient quantity for analysis. Low-cost and easily captured photographic images can replace costly radiographic procedures without causing any discomfort to the patients.
