“…These results seem to be compatible with the angle values of two studies conducted at the same region 47,48. In addition, these results are also compatible with the results of different populations in various regions 42,44,49. However, they are slightly different from Okeke and Omaballa’s results45.…”

“…48 Results of similar studies assessing different regions and populations have also been reported. 40,[42][43][44]46,[51][52][53] The soft tissue total convexity (Gl-Prn-Pg) angle mean values obtained from females and males in our study seem to be compatible with the measurement average results of some studies. 40,42,43,52 In contrast, although the results were obtained from the same population, they differ from the results of Malkoç et al 48 .…”

“…According to a similar study conducted in the Croatian population, the Gl-Sn-Pg (soft tissue convexity facial angle) value in female participants was 169.05° (n=58) and 168.78° in male participants (n=52) 41. In a study conducted in Northern India, it was stated that the mean value of the soft tissue convexity facial angle was 168.54° in female participants (n=72) and 166.64° in male participants (n=78) 42. A similar study conducted in India has proven that specified angle value is 166.67° for female participants (n=37) and 166.29° for male participants (n=34) 43.…”

This study aims to evaluate the relationship between the convexity angle of facial tissue and fingerprint types by analyzing the connection between dermatoglyphic prints and facial structure. A total of 65 adults (24 females, 41 males) participated in the study. Each participant's fingerprint was analyzed using conventional methods of observation upon the index finger of the dominant hand. Fingerprints were classified into 3 fundamental types: arch, whorl, or loop. Craniofacial profiling was performed with measurements of hard tissue (Gl'-A-Pg') and soft tissue facial convexity (Gl-Sn-Pg) and total facial convexity (Gl-Prn-Pg) angles between 3 anthropological points determined on the lateral direct radiographs of the participants. Soft tissue convexity facial angle (Gl-Sn-Pg) values were found to be an average of 166.83°in females and an average of 162.05°in males. (Gl-Prn-Pg) values were found to be an average of 138.54°in females and 135.27°in males. The soft tissue profile of males showed a significantly convex structure compared with females. Also, the "whorl" type of fingerprint was found to be dominant in both sexes. There is no statistically significant difference in terms of soft tissue profile convexity in individuals belonging to the 3 different fingerprint groups. No statistically significant difference in soft tissue profile angular values between right-hand thumb and index fingerprint type groups were found among and between sexes. However, a comprehensive analysis of the relationships between the nose, lips, mouth, ear, and eyes and fingerprints of the same person may prove to be beneficial.

Aim: To present simple photogrammetric techniques that can objectively evaluate standardized digital extraoral and intra-oral photographs for diagnostic and therapeutic purposes. Materials and methods: 11 measurements (9 linear and 2 angular) from standardized lateral photographs were compared with analogous measurements from standardized lateral cephalograms. The study was conducted on 60 subjects (n=60, 41 females, 19 males) aged 18-25 years.8 photogrammetric techniques on standardized photographs, linear and angular photogrammetric analysis on lateral photographs, linear photogrammetric analysis on frontal and frontal smile photographs, photogrammetric analysis of occlusal cant, photogrammetric smile analysis and tooth and intra-arch measurements on occlusal photographs are described. Results: All 11 parameters that were analyzed showed strong correlation. The intraclass correlation coefficients (ICC) and corresponding 95% confidence intervals (CI) of all parameters showed that the reliability of the photographic technique was excellent. Conclusions: Photogrammetry on standardized photographs used in daily orthodontic practice offers a simple, cost effective solution without the hazard of radiation exposure. The 8 photogrammetric techniques described here show that photogrammetry has multiple applications. However, there is a need to standardize photogrammetric techniques, develop multiple photogrammetric analyses for different needs and obtain mean values for parameters from different populations.

Studies have recognized an association between 2D: 4D ratios and testosterone-dependent traits. The aim of the present study is to determine the relationship of 2D: 4D and facial masculinity. Four hundred and two (402) subjects were selected from the two association in Kano state (Tsaya da Kafarka Taxi Drivers Association and Tricycle Operators Association Kano (TOAKAN), using random sampling methods, the age range of the participants between 18-50 years. The lengths of the 2nd and 4th digits were determined by a direct method of measurement. Photographic approaches were used to capture the face, facial masculinity was derived from facial distances (captured image face). We use several approaches of measuring facial masculinity to study the association with digit ratio. The data were expressed as mean ± SD, Pearson correlation was used to quantify the relationships between the 2D: 4D and facial masculinity. None of the facial masculine- measures correlated with both right and left 2D:4D ratios. Keywords: Facial masculinity, 2D:4D (Digit ratio), Photographic methods, Correlation
