Abstract Objectives: The purpose of this study is to find out the correlation between the right and left hamstring length in both genders to determine the prevalence of hamstring tightness among college students. Methods: N=100 subjects were recruited and screened on the basis of inclusion and exclusion criteria. 80 healthy college students were recruited between the age group of 18 to 25 years, sit and reach test was done among the students. Result: The results stated that there is no statistically significant difference between the right and the left hamstring length in both genders and showed high correlation between the hamstring length of right and left of both groups. Chi square test was done and found that there is statistically significant difference between both the hamstring length of both the genders. The left hamstring of male had severe tightness of 27.50% and the right hamstring of female subjects had severe tightness of 45%. Conclusion: The study results concludes that there is significant correlation between the right and the left hamstring length in both groups but there is no correlation of hamstring length when compared with right hamstring length between groups and left hamstring length between groups. Male subjects had comparatively greater tightness in left hamstring and female subjects had right Hamstring tightness. Linear prevalence of Hamstring tightness is greater in female subjects when compared to male subjects.

Objective: To estimate the maximum voluntary molar biting force (MBF) and incisor biting force (IBF) and their relationship to morphological variables in subjects with different vertical skeletal patterns. Materials and Methods: Maximum voluntary MBF, IBF, and morphological variables were recorded in 120 subjects (60 males and 60 females) with skeletal class I pattern in the age range of 14 to 24 years. All subjects were divided into 3 groups: Normodivergent, hypodivergent, and hyperdivergent, according to the maxillomandibular plane angle and Jarabak ratio. Bite force measurements were undertaken using a custom-made portable digital gnathodynamometer on the left and the right sides of the jaw in the molar and incisor regions during maximal clenching. Statistical analysis was performed using independent t-test, chi-square test, and ANOVA test using SPSS version 22.0.0.0 software. Results: MBF and IBF are influenced by gender with higher values obtained for male subjects in all groups in the following order: hypodivergent > normodivergent > hyperdivergent. No significant changes were seen with morphological variables in different groups. Conclusion: Molar and incisor biting forces are highest in hypodivergent subjects and least in hyperdivergent subjects as a reflection of jaw morphology and muscular efficiency. In all groups, males exhibit higher force values than females, underlining a strong gender influence on biting force and facial pattern.

OBJECTIVE: This study assessed the anterior-posterior positioning of the upper and lower first molars, and the degree of rotation of the upper first molars in individuals with Class II, division 1, malocclusion. METHODS: Asymmetry I, an accurate device, was used to assess sixty sets of dental casts from 27 females and 33 males, aged between 12 and 21 years old, with bilateral Class II, division 1. The sagittal position of the molars was determined by positioning the casts onto the device, considering the midpalatal suture as a symmetry reference, and then measuring the distance between the mesial marginal ridge of the most distal molar and the mesial marginal ridge of its counterpart. With regard to the degree of rotation of the upper molar, the distance between landmarks on the mesial marginal ridge was measured. Chi-square test with a 5% significance level was used to verify the variation in molars position. Student's t test at 5% significance was used for statistical analysis. RESULTS: A great number of lower molars mesially positioned was registered, and the comparison between the right and left sides also demonstrated a higher number of mesially positioned molars on the right side of both arches. The average rotation of the molars was found to be 0.76 mm and 0.93 mm for the right and left sides, respectively. CONCLUSION: No statistically significant difference was detected between the mean values of molars mesialization regardless of the side and arch. Molars rotation, measured in millimeters, represented ¼ of Class II.

ABSTRACT Objectives Previous studies showed there were variations in the interforamina distance of mental foramen between races. The aim of our study is to determine the interforamina distance of mental foramen among Malaysian populations. Materials and methods A total of 503 orthopantomogram (OPG) radiographs were observed. Interexaminer calibration was estimated using the Kappa-Cohen formula. A sheet of transparent paper was superimposed on the panoramic film and the mental foramen was traced on it by using a fine marker pen. A vertical line marking the midline was drawn passing between the maxillary central incisors, the mandibular central incisors, or the nasal septum by using a ruler. The distance of the mental foramen from the midline was then recorded from both the left and the right side. The data were analyzed using chi-square test. Results According to our inclusion and exclusion criteria, 110 OPGs have been excluded and 393 OPGs were selected. In the Malay population, the most common interforamina distance for a male is between 55 and 60+ mm (n= 73, 54.8%). Also, the most common interforamina distance for a female is 55 to 60+ mm (n = 84, 50%). In the Chinese population, the most common interformina distance for a male is between 55 and 60+ mm (n=60, 66.8%). Similarly, the most common interforamina distance for a female is between 55 and 60+ mm (n= 73, 53.8%). Among the Indian population, the most common interforamina distance for a male falls between 55 and 60+ mm (n= 53, 43.4%) and for a female as well (n=50, 54%). According to the chi-square test, the results show that the study is statistically insignificant since the p-value is >0.05 for both the male and female population. Conclusion There is no relationship between the interforamina distance and the ethnicity. The most common interforamina distance for all the races falls between 55 and 60+ mm.

Abstract Background: Dengue was reintroduced in Brazil in the 80’s. Since 2010, it is estimated that there have been over a million cases of dengue per year, leading to hundreds of deaths. Community health education is one of the main objectives of vector control policies.Objective: Here we compare perceptions and behaviours before and after an educational intervention based on behavioural change theories (BCT) of a group of Endemic Disease Control Agents (ACEs) with a group of college students of Campina Grande city, Paraiba state, Brazil.Methods: Using a distance-learning platform adapted for mobile devices, the intervention consisted of tasks or missions that were presented through short videos with people performing the desired target behaviour. To demonstrate the accomplishment of the tasks, participants produced videos and shared on social networks. A questionnaire was completed before and after the intervention by 58 participants, 31 students and 27 ACEs. Results: Most of the participants were female (83.9% and 72.2% of college students and ACEs, respectively); 27.8% of ACEs attended higher education and 70.4% were married contrasting with 9.8% of the students. Among college students, a significant difference in the chi-square test was found for all ten-target behaviours after the intervention. ANOVA analysis showed that ACEs have a higher perception of susceptibility and more fear of acquiring arboviruses than students do; and there was a correlation between facilitating behaviours with behaviour change. Conclusion: Intervention based on BCT thus contributed to bring students' behaviour patterns closer to those of ACEs.

DHF is still remains a health problem in Indonesia, especially in Semarang City. Based on data from Semarang City Health Office at 2014, DHF affected  the age group 1-14 years as many sufferers of 1,065 (65%), in children ages 6-12 years old groups only has recorded 336 sufferers (ITP 20.6%). Several protective factors that prevent  mosquito bite in children is wearing pants/skirt length, use of repellent, installation of bednet, and installation of net mosquitoes. The aims of this research was toprove whether wearing long pants/skirt could prevent the occurrence of DHF in elementary students. The design was a case control study. Total sample was 160 children (80 children per group) selected by proportional random sampling with due regard to inclusion and exclusion criteria. Data analysis was bivariate with chi-square test and multivariate logistic regression. There were variables that may prevented the incidence of DHF in school children which were wearing pants/long skirts at home (p=0.003; Or=2,781; 95% CI=1,412-5,476), installation of net mosquitoes in the windows (p=0,018; Or=2,462; 95% CI=1,166-5,200). Results of this research showed that  the occurrence of DHF in children can prevented by wearing pants/long skirts at home, and the installation of net mosquitoes at windows home.

Objective: To determine the various types of maxillary labial frenum attachment in Nepalese children. Materials & Methods: A cross sectional study was conducted in a total of 198 children of age ranging from 1 to 14 years who visited Dental Department of Dhulikhel hospital for routine dental treatment. Types of maxillary labial frenum attachment was recorded along with age and gender. Children were divided into two groups; age 1-7 and 8-14 years. Descriptive analysis was carried out to determine the frequency of frenum types. The relation of frenum with gender and frenum types between two groups were calculated using chi square test. Results: The most common type was gingival attachment {61.1%) and the least common was papillary penetrating type of frenum attachment {8.1%). There was no significant difference in the frenum attachment between the two genders. Mucosal and gingival attachment was significantly higher in older age group whereas papillary and papillary penetrating was higher in younger age group. Conclusion: Attachment of frenum in children changes according to age.
