Objectives: To evaluate the individuality of palatal rugae patten and correlate them in males and females in different age groups by using Trobo’s classification. Study Design: Cross Sectional. Setting: Department of Prosthodontics, Dow Dental College, Dow University of Health Sciences. Period: September 2019 to January 2020. Material & Methods: This study comprised of ninety-four participants with equal number of males and females from 10 years to 70 years, visiting the Prosthodontic department. Study casts included were free of dental abnormality, trauma, malocclusion, orthodontic problems, and deformity in palatal rugae area. Sample size was calculated from software name openepi.com with 95% confidence interval. Data was tabulated and SPSS version 22.0 was used to identify the results. Results: Frequency distribution was performed among age groups in which second group (20 to 39 years) has highest frequency with 52 in number. The cross tab between age group and type of rugae was made which showed group II, having age between 20 to 39 years, had the highest number of palatal rugae configurations amongst all. Conclusion: Sinuous or type E was the predominant type of palatal rugae found in this study. The study did not show significant difference in gender, however number of rugae were found consistently more in young adults with propensity towards individuality. Their use can thus be justified for dental identification in forensic odontology.

Introduction: The palatal rugae are anatomical folds or wrinkles located on the anterior third of the palate behind the incisive papilla on each side of the palatal raphe. The rugae patterns have been studied for various purposes mainly in the field of anthropology, comparative anatomy, genetics, prosthodontics, orthodontics and forensic odontology. This study is aimed to determine the difference in number and pattern of palatal rugae in males and females. Methods: This is a prospective study in which maxillary impressions of 50 volunteers, 25 males and 25 females were taken and the casts prepared. The boundaries of the rugae were marked with a HB pencil and were observed with a magnifying glass following the classification used by Kapali, et al, (1997). Association between rugae number and sex and rugae shape and sex were tested using two sample unpaired t test. Results: The study revealed significant difference in the pattern of converge rugae which were found to be higher in females than males, however, no statistical significant difference was found in the number of rugae between the two sexes. Conclusions: The rugae pattern can be an additional method of differentiation between the males and females in conjunction with the other methods used in forensic sciences. Keywords: forensic science; human identification; palatal rugae.

Indonesia as a disaster-prone area allowed casualty in large numbers and need immediate identification. One way to identify it was the use forensic odontology. Palatal rugae pattern has been suggested as an alternative method in forensic odontology to determine gender in all sorts of ethnic and population. The aim of this study was to know the difference of palatal rugae pattern between males and females in Minang ethnic. This study used descriptive analytics with cross sectional approach. The study sample compromised 122 dental stone casts of Minang ethnic, 61 males and 61 females wih range 15-19 years.  The method rugae identification was based classification of Thomas and Kotze. The data were analyzed by Mann-Whitney test. The most predominant palatal rugae pattern in Minang ethnic are wavy and primary rugae. The Minang males were predominantly wavy, followed by straight, curve, unification, and circular. The Minang females were predominantly wavy, followed by curve, straight, and unification. There was a significant (p<0,05) sex difference in the circular type which was higher in males. Palatal rugae pattern can be used as adjunct to sex differentiation between males and females of ethnic Minang in forensic odontology. Key words : Forensic odontology, analysis of rugae palatal, gender, Minang ethnic

Knowledge of acetabular morphometry parameters namely acetabular inclination and anteversion angles beside acetabular depth aid surgeons to accurately plan hip replacement procedure. The current hip implants designed based on Caucasian population which may not accurately match morphologic features of our population. Our objective is to determine normal acetabular morphometric parameters from CT scans of Malay patients in Hospital Universiti Sains Malaysia and compare gender and age group differences. A cross-sectional study was done within 18 months duration from November 2010 till May 2012. A total of 133 samples collected and divided into four age groups. Mean and standard deviations for all parameters were determined. No significant difference between acetabular parameters among males and females (p>0.001). Significant difference between age groups noted, mainly in group 1 (18 to 30 years) with group 4 (51 to 60 years) in all parameters. As for conclusion, no significant parameter differences between genders, hence no indication for gender or population specific hip implants. Significant differences noted when parameters compared between age groups, especially between the two extremes of age groups.

Introduction. Chest X-ray (CXR) is used for the initial triage of patients with suspected COVID-19. Studies of CXR scoring in the European population found a higher score in males than in females and significantly correlated with age. Because there have not been studies in the Mexican-mestizo community, we aimed to compare the differences in CXR scores between males and females and their correlation with age after controlling comorbidities like diabetes and hypertension. Materials and Methods. A retrospective study of 1000 CXR of Mexican-mestizo patients with SARS-CoV-2 infection, confirmed by RT-PCR. Significant differences between age, age groups, symptoms, comorbidities, and CXR scores between males and females used the Mann–Whitney U , Chi-square tests ( χ 2 ), and Kruskal–Wallis tests. The relationship between the total CXR score and age was measured with the Spearman rank correlation coefficient (Rs); partial correlation analysis controlled the effect of symptoms, risk factors, and comorbidities. Results. The total CXR score did not show a difference between males and females grouped by age. There was a positive, low correlation between the total CXR score and age in males, Rs = 0.260 , p < 0.001 ( N = 616 ), and in females, Rs = 0.170 , p = 0.001 ( N = 384 ). Age only explained a <9% variance of CXR severity. Rs decreased its magnitude (from Rs = 0.152 to Rs = 0.046 ) and lost its significance (change in p value from p < 0.001 to p = 0.145 ) after controlling the effect of hypertension. Conclusions. There is no significant difference in CXR score between males and females in the Mexican-mestizo population grouped by age. Hypertension cancels the significance of CXR severity with age pointing to its role in the pathophysiology of COVID-19. Further research using stratified groups by age and gender in other populations needs to be published.

Introduction: Creation of anthropometric database in any age group is one of the most important issues in designing and manufacturing of used equipment. The aim of this study was to determine the anthropometric characteristics of nurses of kindergartens and preschools in Isfahan in the age range of 2 to 6 years and to create an information reference.Materials and Methods: In this applied study, 700 healthy male and female boys were selected randomly from cluster sampling from nursery schoolchildren and preschools in Isfahan city. 36 anthropometric measurements of them were cross-sectional in the academic year 1396 to 1397. And indicators and statistical percentiles (5.50 and 95) were extracted.Results: Statistical indexes and percentiles were presented as an anthropometric database in 5 age groups and in two sex groups. Age and sex were influenced by most anthropometric variables and significant difference (P <0.05). .Conclusion: The age and sex are two factors affecting anthropometric variables. Therefore, it is necessary to use the anterpometric database of the same age group and gender in the design of the equipment.

INTRODUCTION: Bone mineral density(BMD) is a common test done in our country. Traditionally, BMD has been reserved for postmenopausal females to check for risk of osteoporosis. The aim of this study is to check whether BMD score showed difference between males and females and across different age groups. Also, we tried to examine any correlation between Vitamin D and BMD values. MATERIAL AND METHODS: It was a cross-sectional observational study.118 healthy subjects of both genders were recruited. BMD was measured by dual energy X-ray absorptiometry(DEXA). Vitamin D was estimated by electrochemiluminescence. Statistical Analysis: Data was entered in to MS Excel and analyzed by STATA 12 software. Normality was analyzed. Mean and SD for all variables were calculated. Difference in T-score between males and females were calculated using T-test and T-score in different age groups was compared using one-way ANOVA test. Vitamin D levels were correlate with T-scores by Spearman's correlation test. RESULTS: Mean age of subjects was 51.31 years. Mean T-score was -1.40. Mean Vitamin D was 23.45 ng/ml. There was no significant difference between T-score of males and females. T-score was also not significantly different across age groups from 20 to 80 years. Vitamin D was not correlated with T-score in same subjects. Osteopenia was present in 74 subjects and osteoporosis in 11 subjects. DISCUSSION: Contrary to popular opinion, T-score was not different between males and females, therefore there is a need for uniform BMD criteria for both genders. Vitamin D levels alone are unreliable as they do not correlate with T-score. CONCLUSION: Thus, there is a need for revised T-score guidelines and additional tests like serum calcium, BMI, serum parathormone which needs to be done and examined together with BMD and Vitamin D to identify bone demineralization in the population.

The aim of the current study was to identify the level of cognitive distortions among the patients suffering from psychiatric disorder according to age, gender and educational qualification. Cross sectional survey method was followed, using Bangladesh Cognitive Distortion Scale (BCDS, Siddika and Chowdhury, 2013) on 239 patients, suffering from anxiety and depression for assessing cognitive distortion. Among the psychiatric patients 86.2% respondents found to have clinical level of cognitive distortion. Analysis revealed that there is no significant difference in cognitive distortion according to different age groups and gender. But regarding educational qualification, there is significant difference of total score of Bangladesh cognitive distortion scale (p > 0.01) and it is higher among low literate respondents (non institutional to class 5) than high literate.

Introduction: Elastic modules are an integral part of fixed appliances. The availability of different colours is important to patients and their compliance during treatment. Knowledge about the most popular colours is important to orthodontists when ordering their materials. Aim: This study aimed to determine the elastic ligature colour preferences of patients undergoing fixed orthodontic treatment and the influences of age and gender on these preferences. Materials and Methods: This cross-sectional study was done on a total of 319 patients (88 males and 231 females) aged 18-36 years of age participated in this study. The patients’ elastic ligature colour preferences were recoded using a colour guide and a self-administered questionnaire. The questionnaire contained questions about the patients’ preferences regarding coloured or transparent ligatures, light or dark shades, and changing the ligatures for specific occasions. The data were analysed using SPSS version 25. The descriptive statistics were calculated, and a Pearson’s chi-squared analysis was performed to determine the influence of age and gender effects on colour preferences (p-value <0.05). Results: Most of the participants were excited about changing their elastic ligatures colours (44.5%), and they liked to change the colours at each visit (45.5%). Most participants did not like having multicoloured elastic ligatures in their mouths (77.4%) or changing the elastic colours before certain occasions (49.8%). There was no statistically significant difference in the elastic ligature colour preferences between the genders (p-value=0.0552), but there were statistically significant differences among the age groups (p-value <0.001). Conclusion: Most of the patients undergoing orthodontic treatment with fixed appliances preferred less noticeable elastic ligature colours. A significant difference was found between age groups: younger patients preferred coloured elastics, while older patients preferred less noticeable and transparent elastics. No difference was found between the colour preferences among both the gender.

OBJECTIVES:  To analyze the impact of age and gender on iron stores in a population of the Nowshera region. METHODOLOGY: This cross sectional study was conducted in the Department of Pathology Qazi Hussain Ahmed Medical Complex Nowshera from 1st January 2019 to 31st March 2020. All patients were selected by convenience sampling in the Pathology department irrespective of age and gender.   Both descriptive and inferential statistics were applied to analyze data by the latest SPSS version 25.  RESULTS: Out of the total study population males were 70 (27.1%) and females 188 (77.9%) with median age 30 years.  The median ferritin level was 12.8 ng/ml. Out of total, 142 (55%) of cases were with serum ferritin less than 15ng/ml. A significant (p=0.03) gender based median ferritin level difference was observed with 1.5 times more probability of low iron stores in females as compared to males (OR=1.5). No statistically significant difference in body iron stores exists in different age groups. CONCLUSION:  A significant difference was noted in the iron stores in gender groups and the probability of depleted/low iron stores was higher in female gender as compared to male gender in all age groups in our population.

Background & Objectives: The current study was conducted to identify and determine the association between gender and characteristics of palatal rugae in Nepalese population.  Materials & Methods: Characteristics of palatal rugae including number, length, shape, direction and unification were analyzed in 100 maxillary dental plaster casts.  Association between palatal rugae and gender were tested using chi square analysis and statistical descriptors were identified using SPSS 10.0 keeping the level of statistical significance at p<0.05. Results: A total of 997 rugae were traced. Females were found to have more rugae than males though statistically not significant. In the present study significant difference in secondary (p=0.012), fragmentary (p=0.005), straight (p=0.001) and perpendicular directed (p<0.0001) palatal rugae were observed, which were higher among females. Forward directed followed by backward were predominantly observed and more among females. Wavy followed by curved, straight and circular rugae was the most prevalent shape.Conclusion: No two individual had similar rugae pattern. They can be used to identify people and differentiate between males and females in addition to other tools of identification and has great application in forensic science.
