Introduction: Crown diameters of a teeth are reasonably accurate predictors of sex and are good adjuncts for sex determinations. The aim of the study was to determine the reliability of mesiodistal width of mandibular canine in sexual dimorphism. Materials and methods: Medical students of Nepalgunj Medical College, Chisapani, Banke, Nepal were selected for data collection. Sample consisted of 300 subjects which included 150 males and 150 females of age group 18-25 years. The mesiodistal width of the mandibular right and left canine teeth were recorded by Vernier calliper. Descriptive statistical analysis was done from odontometric measurements data to calculate sexual dimorphism for mandibular right and left canine. The student t-test was used to determine the level of significance among the parameters measured. Results: The mean values for mesiodistal width of mandibular right canine for male and female subjects were 7.1665±0.28576 and 6.3777±0.37875 respectively. The sexual dimorphism for mandibular right canine was calculated to be 12.368%. The mean values for mesiodistal width of mandibular left canine for male and female subjects were 7.3875±0.35506 and 6.2847±0.41115 respectively. The sexual dimorphism for mandibular left canine was calculated to be 17.5%. Conclusion: Statistical analysis showed significant sexual dimorphism in odontometric analysis of permanent mandibular canines between male and female with the mandibular left canine showing the highest percentage.

Objectives. To evaluate the tooth size discrepancy and Bolton’s ratios between male and female subjects with a Class I malocclusion. Materials and Methods. The digital e-models of 100 male and 100 female 12-year-old southern Chinese children with a Class I malocclusion were selected. The mesiodistal widths from permanent first molar to the contralateral side first molar of the upper and lower dentitions were measured. Differences between the tooth size discrepancy, together with the anterior and overall Bolton’s ratios between male and female subjects, were assessed using a two-sample t-test. A paired t-test was used to determine differences between antimetric pairs of teeth within the same arch. Results. Females had statistically significant smaller teeth than males (P < 0.05) except the upper left and lower left lateral incisor and lower left and right central incisors. The mean values of anterior Bolton’s ratios for males and females were 77.04 and 77.03, respectively (P > 0.05), while the mean values of overall Bolton’s ratios of male and female are 90.48 and 90.65, respectively (P < 0.05). The clinical significant differences (Cohen’s d > 0.2) for contralateral tooth size were shown on the maxillary canines, lateral incisors, and central incisors of males; and mandibular canines and lateral incisors of females. Conclusions. Southern Chinese females presenting with Class I malocclusions have smaller mesiodistal tooth dimensions compared to males. Both males and females presented several tooth size asymmetries. There are no statistical differences in anterior and overall Bolton’s ratios between the genders.

The aim of this study was to determine the nasal parameters in the population of central Serbia and to compare them with those determined in earlier studies in different populations. The research was conducted on 496 randomly selected persons (262 males and 234 females), aged 18-65 years. The measured parameters were nasal height and nasal breadth and the standard spreading caliper with scale was used for measurements. There were significant differences in the nasal parameters between male and female subjects. The nasal breadth was 34.72 mm in females, and in the male population it was 36.7 mm. The mean values of nasal height were 52.6 mm and 54.32 mm in females and males, respectively. The nasal index in females and males was 66.01 and 67.56, respectively, and the mean value of the nasal index of all respondents was 66.78. After conducting the research it was concluded that the dominant nasal type in the population of the central part of Serbia is leptorrhine. The present study showed the existence of sexual dimorphism in nasal morphology. The data obtained in our study may be useful in anthropological and forensic research, as well as in cosmetic planning and reconstructive surgery.

BACKGROUND Femur is the longest and strongest bone of the human body. It also takes relatively longer time to disintegrate after death, hence morphometric analysis of skeletal remains of femoral head can be considered for the determination of age and sex for forensic expert, anthropologist as well as anatomist. The present study was an attempt to establish sex of a skeleton by the help of femoral head diameters which will be of great help in medico-legal and anthropometric studies. METHODS The present study was carried out in the S C B Medical College Cuttack from May 2019 to June 2020 by taking 84 dried and intact femora. The vertical head diameter of femoral head and head circumference were measured by the vernier’ s caliper and measuring tape in centimeters. RESULTS The result showed significant difference in the head circumference and the vertical diameter of head of femur of the male and female femora. It was found that the mean femoral head circumference of the male was 13.296 cm with a “S.D” of 0.8694 cm and female was 12.023 cm with a “S.D” of 0.73 cm and vertical diameter of male was 4.1520 cm with a “SD” of 0.3635 cm and that of female femora was 3.7231 cm with a “S.D” of 0.2264 cm respectively. CONCLUSIONS There was a significant difference in the head circumference and the vertical diameter of head of femur of the male and female femora which determines sexual dimorphism.

The Difference

Context : It has long been customary among anatomists, anthropologists and forensic experts to judge the sex of the skeletal material by non-metric observations. Afterward the study of sexual divergence has been based upon actual measurements in different bones. The study in relation to metrical data on bone is very few in our country. The study was planned to observe the differences of sacra between male and female in respect to measurement of alar length and auricular index of sacrum. The findings of this study might be useful in providing morphometrical data that can be used by anatomists, forensic experts, anthropologists, orthopedic surgeons and neurologists for proper initiative in their respective fields. Materials and Methods: A cross-sectional, analytical type of study was performed in the department of Anatomy, Dhaka Medical College, Dhaka from January 2011 to December 2011. A total of 172 (one hundred seventy two) adult human dry sacra of unknown sex was assessed. The study samples were distributed in male and female sex groups by discriminant function analysis. All the samples were studied morphologically. Length of ala and auricular surface were measured with the help of digital slide calipers. Results: The mean length value of ala was greater in female than male (P<0.001). The difference between the mean value of alar index in male and female was significant (P >0.05). The mean value of auricular index was higher in male than female and the difference was statically significant (P<0.001). Conclusion: The sacrum can be used for sexual dimorphism as is usual in anthropological work. The knowledge of alar length and auricular index of sacrum is essential in medico-legal practice for sex determination of an individual.

This study was carried out to determine the modern office technology competencies expected of office technology and management (OTM) graduate workers by supervisors in Delta State. The study was guided by two research questions and two hypotheses tested at 0.05 level of significance. The respondents consisted of 142 supervisors, made up of 74 heads of department and directors of government establishments, and 68 managers and directors of private establishments in the study area. Descriptive survey research design was used to conduct the study and 28 – items questionnaire were used to collect data from respondents. The instrument was validated by three experts and had a Cronbach Alpha reliability coefficient of 0.77. Means with standard deviations were used to answer the research questions, while t-test was used to test the null hypotheses. The extent of supervisor‟s expectations of information processing competencies did not differ significantly based on the mean ratings of male and female supervisors of OTM graduates in government and private establishments. The findings also revealed that supervisors expect much information processing and communication competencies from the OTM graduate workers. Based on the findings and the implications, it was recommended among others that, curriculum planners, business and OTM education lecturers should ensure that the competencies required for modern office technologies are entrenched and taught in the institutions to prepare the OTM graduates for the world of work.

The aim of this study was to apply the morphometric quantification of the canine index for sexual dimorphism in a Brazilian sample. The sample consisted of 90 participants (45 males and 45 females) aged between 18 and 35 years. With the aid of a digital caliper, the intraoral mesio-distal measurement of the permanent mandibular right canine (MD43) and the intercanine distance (IC) were taken by three examiners. The measurements were used in a formula established by Rao, Rao, Pai e Kotian (1989) to estimate sex based on morphometric features of the human canines. The applicability of this approach for sexual dimorphism was assessed based on the inherent mandibular canine index (MCI) calculated by the formula. The MCI was higher in males than females. The mean general accuracy rate of the MCI for sexual dimorphism in the total sample was 52.22%. In males, the MCI was able to properly distinguish sex in 82.22% of the sample, while in females the accuracy decreased to 22.22%.  These outcomes raise the attention for the careful use of the MCI in practice – especially in the field of Forensic Anthropology. In particular, the accuracy of the method was close to random in a sample that contained both sexes. Thus, MCI should not be used as the only tool for sexual dimorphism.
