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.

Background. External ear measurement is of utmost importance in reconstructive surgeries. Objectives. The present study is aimed at ascertaining sexual dimorphism in external ear anthropometry and ear lobe attachments among adults Ijaws in Bayelsa, Nigeria. Methods. A total of 112 adults within the age range of 18-50 yrs, who met the inclusion criteria, were involved in the study. Four linear dimensions of the ear, which are ear length (EL), ear width (EW), lobular length (LL) and lobular width (LW), were measured for both genders. The lobular attachment for both ears for males and females were also examined and results recorded. These data were subjected to Student t-test, Chi-square test, and Pearson’s correlation using SPSS version 20.0. Results. The mean values for EL, EW, LL, and LW for the left auricle in the males and females were 58.14±0.60, 27.41±0.37, 14.47±0.27, 13.50±0.34 and 57.90±0.16, 27.45±0.65, 15.41±0.31, 13.43±0.38 respectively. However, for the right auricle in the males and females, the values were 58.40±0.45, 28.21±0.68, 14.32±0.31, 13.04±0.32, and 56.66±1.10, 27.51±0.65, 15.58±0.29, 13.28±0.34 respectively. The left and right lobular length were the only parameters that proved statistical significance (p<0.05) in females compare to males. Pearson’s correlations between right and left sides for each of the parameters were positive and significant. Chi-square analysis revealed no significant relationship (p>0.05) between earlobe attachments and gender. Conclusions. Sexual dimorphism was thus established in the Ijaw population as regards lobular length dimensions. It is believed that the results of this study would be very useful for ear morphology and reconstructive surgeries.

Objectives: To determine the color preferences for elastic ligatures among patients receiving fixed-appliance orthodontic therapy.Methods: Five hundred patients with metal brackets (336 female patients and 164 male patients) were included, and their color preferences for elastic ligatures were recorded using a color scale. Chi-square analysis was performed to evaluate the color preferences and to determine the influence of age and gender on color preferences (P<.05).Results: Two hundred and seventy-six patients (55.2%) preferred strikingly colorful elastic ligatures, while 224 patients (44.8%) preferred less noticeable elastic ligatures. No significant difference was observed between the color preferences of female and male patients (P>.05). However, significant differences were observed between the color preferences of adolescents and older patients (P<.001).Conclusions: Female patients preferred red–purple-colored tones, while male patients preferred blue–black-colored tones. Adolescents preferred colorful elastic ligatures, while older patients preferred ligatures with less-noticeable colors. A stock of 10–12 colorful and less-noticeable elastic ligatures seems to be adequate to ensure patient satisfaction. (Eur J Dent 2010;4:171-174)

ABSTRACT Background Human identification is one of the most challenging subjects that man has been confronted with. The fingerprints and DNA comparison are the most commonly used techniques in human identification. Palatoscopy is one of the recently developing methods to identify a victim-based on the palatal rugae pattern. Aims and objectives The aim of the study was to analyze the different rugae pattern in Puducherry population and to find whether palatoscopy is a useful tool in human identification and sex determination. Materials and methods The studies consist of 100 male and female patients between the age group of 20 to 35 years. The rugae pattern was divided assessed based on Kotze classification. Chi-square test and one-way analysis was used to study the statistical significance. Results Wavy pattern appeared to be the most predominant pattern followed by curved, straight, branched and circular pattern in both male and female patients. The shape and number of rugae pattern is similar in male and females. Conclusion The present study concludes that wavy pattern appear to be most common rugae pattern among Puducherry population. No significant difference in rugae pattern was noted among the male and female group. Rugae pattern is unique to each individual and can be an effective tool in human identification.

Objectives: Although the glenoid labrum is linked to glenohumeral joint stability, its anatomy remains controversial. This study aimed to investigate the shape, consistency of the glenoid labrum, and whether these and its thickness and depth are age related. Methods: A total of 140 shoulders were dissected to expose the glenoid labrum. the shape and consistency of the glenoid labrum were assessed at a gross level. Measurements were taken of the labrum depth and thickness, using callipers, in the superior, anterior, inferior and posterior regions. ANOVA and chi-square tests were conducted to determine statistical significance, which was set at p<0.05. Results: The consistency of the superior half of the labrum was rubbery in 97.9% of specimens and firm in the remaining 2.1%, whereas the entire inferior half was firm. There was a significant difference (p=0.043) in the consistency of the superior half between males and females. The superior half was triangular in 95.7% of specimens, flat in 2.1% and flat to triangular in 2.1%, whereas the shape of the inferior half was rounded in 99.3% of specimens and flat in 0.7%. The labrum was observed to be thicker in younger individuals, with the differences being significant superiorly (p=0.011), anteriorly (p=0.050), inferiorly (p=0.001) and posteriorly (p=0.047). It was also observed to be deeper in younger individuals, but only significantly so superiorly (p=0.044). Conclusion: Labrum thickness and depth significantly decreased with increasing age, suggesting that these observations could be age-related.

This study was conducted to investigate the problem of demotivation in English language learning (ELL) within the Moroccan context. To attain this objective, two instruments were adopted: a questionnaire and a writing test. The participants involved in this study were 201 baccalaureate students (second year) from six secondary schools, 84 were males and 117 were females. The data gathered was quantitatively analyzed through frequency distribution and percentages, Cross-tabulation, Chi-Square Tests, Independent Samples t-Test, in addition to the statistical significance which was set at the level of .05 (95%) for all statistical procedures. Six main findings were reported: (1) students positively perceived themselves in ELL; (2) students did not consider English language as a demotivating factor while learning it itself; (3) students were largely positive towards their teachers of English; (4) crowded classrooms were the main demotivators in learning environment among classmates, textbook of English, and classroom atmosphere; (5) generally, learning environment was the main demotivating factor in ELL; (6) as for gender, there was no significant difference between males and females in terms of the number of demotivating factors that they encountered. In the light of these findings, some pertinent implications were provided.

The prevalence and pattern of presentation of severe malaria differ from one area to another, in one age group and gender. A descriptive cross sectional study of children between the ages of one month and fourteen years with symptoms of severe malaria was conducted between July and December 2018 in Dutse and Birnin Kudu Local Government Area of Jigawa State. Venous blood samples were used for parasitological, hematological and biochemical examination following standard procedures. Thick and thin blood films were prepared, stained and examined at x100 magnification. A total of 172 children were considered in which, 73/167(43.7) children had severe malaria. Children less than 5 years of age had the highest percentage of severe malaria (47.1%; 95% CI = 39.5 to 54.7). Hyperpyrexia, prostration, hyper parasitemia and multiple convulsions were the commonest presentations. While metabolic acidosis, jaundice, hypoglycemia and respiratory distress were the least presenting features, no child presented spontaneous bleeding or shock. Furthermore, 21/73 children with severe malaria had only one feature of severity, 32/73 (43.8) had two features of severity, while 14/73 (19.2) of the children had up to three features. Only 4/73 (5.5) children had four of the features of severity. Chi-square analysis showed significant difference (P <0.05) in prostration and multiple convulsions among children less than and above 5 years. The prevalence of severe malaria in less than five years old is high; hence care givers should present symptoms early to the hospital in order to prevent progression to severe life threatening malaria.

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.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

Background: The palatal rugae are special constructions that are inalterable in their position and pattern during the lifestyles of an individual. This imparts them an exceptional role in the forensic dentistry and may play potential role in malocclusion identification. This study was aimed to see association of rugae pattern with sagittal skeletal malocclusion in orthodontic patients visiting tertiary care hospital. Methods: This cross-sectional examination was completed on pretreatment records (lateral Cephalometric radiographs and maxillary dental casts) of 384 subjects at the orthodontic department of Ziauddin Dental Hospital, Karachi. The study duration was from January to July 2019. The samples were sub-divided into three sagittal skeletal groups based on ANB angle proposed by Steiner’s on lateral Cephalometric radiographs (Class I with ANB angle between 0° to 4°; Class II: ANB angle greater than 5°; Class III: ANB angle less than 0°). The shapes of three most-anterior primary rugae were then evaluated bilaterally using Kapali et al., Classification. Chi Square test was applied to find association of rugae pattern among sagittal skeletal malocclusions groups. Results: Circular and curved rugae shapes were the most prevalent in all skeletal malocclusions. The primary palatal rugae pattern was seen to be significantly different among three skeletal malocclusion groups (p<0.05). The right and left sided palatal rugae pattern showed significant difference in all three skeletal malocclusion groups (p<0.05). Conclusion: The present study showed no specific palatal rugae pattern associated with sagittal skeletal malocclusion. Further studies on larger sample and use of modern 3D technologies to scan the maxillary casts are required for results that are more precise.

AbstractIntroduction:To determine the awareness of citizens and physicians concerning the capabilities of a rural emergency medical services (EMS) system.Hypothesis:Citizens and physicians are unaware of the capabilities of the EMS system.Methods:Residents were selected randomly from the local telephone directory and asked a series of structured questions about their EMS agency. A written survey was distributed to area physicians. Chi-square analysis was used to compare the proportion of respondents who knew the available interventions in their community with the proportion of those who did not. Statistical significance was inferred at p <0.01.Results:A total of 49% of the citizens were able to identify available skills, and 41.4% of the physicians were able to identify available skills. Physicians were less likely than were the citizens to be able to identify the skills performed by each provider (p <0.001).Conclusion:This study indicates that both physicians and the lay public have little understanding of the capabilities of their EMS system.
