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.

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.

Forensic odontology in dentistry is used to identify victims. Several methods can be used, such as rugoscopy. Rugoscopy is a victim identification method by evaluating the palatal rugae. Rugoscopy is very advantageous due to its low cost, fast results and practical nature. Palatal rugae is protected from trauma and high temperature due to its internal position in the oral cavity. Palatal rugae is an individualistic structure, though it bears several resemblance with the hereditary pattern due to the polygenic mechanism. The purpose of this research is to determine the difference of palatal rugae shape and size between uncle and nephew in Minangkabau ethnics. This study is an analytical observational study with a cross sectional approach. A total of 78 pairs of uncle and nephew of the Minangkabau ethnicity in Luhak Nan Tigo. Palatal rugae is classified using the Thomaz and Khutze classification. Data were analyzed by using Mann Whitney non-parametric statistical analysis. Data analysis show the palatal rugae shape of uncle and nephew from the Minangkabau ethnicity is dominated by a wavy shape, followed by curvy, straight, unified and circular shapes. The palatal rugae size of uncle and naphew from the Minangkabau ethnicity is dominated by primary size, followed by secondary and fragmenter size. Mann Whitney analysis revealed no significant difference of palatal rugae shape and size between uncle and nephew in Minangkabau ethnics (p>0,05), though there is a significant difference in the unified shape (p<0,05). Palatal rugae shape and size have a similar pattern with hereditery patterns, though not identical. Palatal rugae may be used as a secondary method of victim identification Keywords : Rugoscopy, palatal rugae, uncle and nephew

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.

Abstract Background: Accidental paediatric poisoning is a common medical emergency and also associated with a high morbidity and mortality in children. In developing countries like India, the poisoning emergencies are becoming a major cause of mortality in infants and toddlers. Among the various studies done on poisoning cases in our country, the study on poisoning is more or less only on adults and hence this study is taken up to understand the number of childhood poisoning cases (based on gender). Method: A ten year record based cross sectional study from January 1999 to December 2008 was conducted at the Department of Forensic Medicine & Toxicology, Kasturba Medical College, Manipal, to understand the magnitude of childhood poisoning cases among males and females at Kasturba Hospital, Manipal. Results: Male children were predominantly affected (male: female::1.32: 1). Most of the poisoning cases occurred at home in both the genders with boy to girl ratio based on percentage in indoor poisoning being 0.92:1 and boy to girl ratio based on percentage in outcome being 1.06:1. Conclusion: Our study examines the difference in place and outcome of poisoning among boys and girls to identify population at risk and give suggestions so as to reduce the morbidity and mortality.

Introduction: Cheiloscopy is considered as an emerging method in forensic odontology for identification of gender. There are several methods given in literature to identify the lip print types. Digital photographs can be used to study the lip prints for gender identification. Objective: The aim of the study was to identify the predominant lip print pattern in males and females by using digital photographs. Methods: This analytical cross-sectional study included 206 subjects, comprising 103 males and 103 females. Digital photographs were used to identify the lip print patterns. The classification given by Suzuki and Tsuchihashi was used to further classify the lip patterns. Kappa test was applied to check for inter observer variation. Statistical analysis was done using SPSS version 23. The association between gender and lip print type was tested by Chi square test. Results: Type I was the most common lip print followed by Type I’. Type V was the least common lip print followed by Type IV. Type I and Type II were the most common pattern in females and males respectively and these differences were found to be statistically significant (p<0.01). Conclusion: Digital photographs are very useful for identification of lip print pattern. The variation in lip print pattern among males and females can be taken as an aid in gender determination.

Abstract Introduction Palatal rugae or plica palatine are the finger prints of the oral cavity and the arch length varies between males and females. These two parameters constitute an integral part of the anthropometric studies in the realms of dentistry as well as forensic odontology. The aim of this study was to assess whether any relationship existed between the upper arch length and the rugae pattern and whether these two parameters showed any gender differentiation. Materials and Methods The sample consisted of upper and lower study models of 60 subjects (30 males and 30 females). Arch lengths were measured using a brass wire and rugae were traced on the dental casts and assessed by applying the Thomas and Kotze classification (1983). The data collected was subjected to statistical analysis. Results The results showed that the maxillary and mandibular arch length dimensions were higher in males than in females; however, the differences were found to be statistically insignificant. The assessment of rugae pattern showed that the male subjects had a higher number of rugae. The differences in rugae pattern distribution for male and female subjects were found to be statistically significant. Conclusion The palatal rugae pattern and maxillary arch length can be used as an additional method in differentiating gender between human population groups.

This study reported herein aimed to reveal prospective teachers’ misconceptions about classification of plants and the effect of pre-service education program on their correct conceptions of this biological issue. Prospective teachers majoring in Elementary School Classroom Teacher Education constituted the target population of this study during the fall semester of the 2012-2013 academic years from Turkey. In order to reveal the difference between the misconceptions of prospective teachers who are at the beginning and at the end of their university education, the research was conducted as a cross-sectional study (78 first and 84 fourth class). The results showed that the prospective teachers in both groups have misconceptions and considerable confusion over the concepts of without-seed plants, seedy plants, vascular plants, non-vascular plants, gymnosperm plants, angiosperm plants, fruit and vegetable. In addition, the pre-service education did not seem to have an important effect on correction of prospective teachers’ misconceptions about classification of plants. In this context, prospective teachers are graduated with misconceptions about classification of plants. Key words: biology, classification of plants, misconceptions, prospective teachers.

ABSTRACT Objective: The present study is intended to add a new parameter that would be useful in orthodontic clinical evaluation, treatment planning, and determination of vertical dimension (at occlusion). Materials and Methods: Standardized videographic recording of 79 subjects during posed smile was captured. Each video was then cut into 30 photos using the free studio software. The widest commissure-to-commissure posed smile frame (posed smile width [SW]) was selected as one of 10 or more frames showing an identical smile. Lower third of the face is measured from subnasale to soft tissue menton using a digital vernier caliper. Two values were then compared. Ratio between lower facial height and posed SW was calculated. Results: The co-relation between smiling width and lower facial height was found to be statistically significant (P < 0.01). The ratio of lower facial height and smiling width was calculated as 1.0016 with a standard deviation (SD) = 0.04 in males and 1.0301 with an SD = 0.07 in females. The difference between the mean lower facial height in males and females was statistically significant with a t = 10.231 and P = 0.000. The difference between the mean smiling width in males and females was also statistically significant with a t = 5.653 and P = 0.000. Conclusion: In class I subjects with pleasing appearance, normal facial proportions, normal overjet and overbite, and average Frankfort mandibular angle, the lower facial height (subnasale to soft tissue menton) is equal to posed SW.

BackgroundMany individuals with migraine report symptoms of dry eye (DE). However, it is not known whether DE profiles are similar between individuals with and without migraine. To bridge this gap, we evaluated symptoms and signs of DE, including symptoms suggestive of nerve dysfunction, in a large group of individuals with DE symptoms, and compared profiles between individuals with migraine and those without migraine or headache.MethodsProspective cross-sectional study of individuals with DE symptoms seen at the Miami VA.ResultsOf 250 individuals, 31 met International Classification of Headache Disorders criteria for migraine based on a validated screen. Individuals with migraine were significantly younger (57 vs 62 years) and more likely to be female (26% vs 6%) than controls. Individuals with migraine had more severe DE symptoms and ocular pain compared with controls (mean Ocular Surface Disease Index 53.93 ± 21.76 vs 36.30 ± 22.90, p=0.0001; mean Neuropathic Pain Symptom Inventory modified for the Eye 39.39 ± 23.33 vs 21.86 ± 20.17, p=0.0001). The difference in symptom profile occurred despite similar ocular surface parameters between the groups.ConclusionsIndividuals with migraine had a different DE symptom yet a similar DE sign profile when compared with controls without migraine. This suggests that DE symptoms in individuals with migraine may be driven by nerve dysfunction as opposed to ocular surface abnormalities.

The Neutrophil-Lymphocyte Ratio (NLR) and procalcitonin are used to indicate systemic inflammation in variousmedical disorders. Both parameters were determined in this study to predict the severity of acute pancreatitis. This studywas a cross-sectional study using a retrospective approach to patients diagnosed with acute pancreatitis by using medicalrecord data from patients at Dr. Wahidin Sudirohusoso Hospital, Makassar, from January 2014 to May 2019. This studycomprised 35 patients hospitalized with acute pancreatitis, with a similar proportion of males and females. This studydiscovered that the mean age in this study was 44.17±12.9 years. The most prevalent cause was Gallstones (77.1%), themost severe degree was mild (54.2%), and the highest outcome was survival (77.1%). The NLR (9.93±11.19, p=0.011)increased in proportion to severity. However, additional analysis based on classification of disease severity revealed thatonly mild-severe NLR was significant (p=0.005). Procalcitonin (8.13±11.25, p=0.001) increased along with the increaseddisease severity, and the subsequent analysis showed that the distribution of severity was similar. The NLR can predict theseverity of acute pancreatitis but is less effective than procalcitonin. This study required a more proportional subjectpopulation and consideration of other factors.
