Objective: To evaluate patient perception of the smile focused on analysis of the upper incisors. Design: Cross-sectional study. Setting: Department of Clinical and Social Dentistry at Federal University of Paraíba, João Pessoa, Brazil. Participants: The sample consisted of 135 individuals (73 women and 62 men). Methods: Images with different characteristics associated with the incisal edges were shown at random and analysed using a Likert scale. Data were analysed using the Chi-square test or Fisher’s exact test with a statistically significant difference ( P < 0.05). Results: Smile I (difference of 1.5 mm in relation to the central incisor and lateral) was considered the most aesthetic, while Smile III (no difference in height between the central and lateral incisors) was the least aesthetic. A significant difference was found between perception of smile II (difference of 1 mm in relation to the central incisor and lateral) and age groups ( P < 0.005), with 31% (n = 13) of individuals aged 45–64 years considering smile II as not pleasant, 4.4% (n = 2) aged 15–24 years and 8.3% (n=4) aged 25–44 years and 4.4% (n = 2) aged 15–24 years considering the same. A significant difference was also found in relation to educational background of the assessor and smile perception, with smile III ( P = 0.0441) and smile IV ( P = 0.0053) considered the most aesthetic ( P = 0.0116). Conclusion: The smile considered most attractive among the sample was that with 1.5 mm steepness between the central and lateral incisors, while a flat smile arc was considered least attractive.

ABSTRACT Objective: to determine the prevalence of use in life and in the last three months of alcohol, marijuana and cocaine among university students from the social and health Sciences areas of Ribeirão Preto, Brazil and to evaluate the association between use in life and in the last three months of alcohol, marijuana and cocaine and the variables gender, area of the course, with whom the student lives, importance of religion, age and year of study. Method: a cross-sectional study, carried out with a convenience sample of 275 students from a public university in Ribeirão Preto-SP. For data collection, two instruments were used, containing sociodemographic, training and psychoactive substances. For the analysis, the following tests were used: Fisher's exact test, Chi-square test of Person and Mann-Whitney test. Results: As for sociodemographic factors, there was a significant association between the gender of the participants among the use of marijuana and cocaine in life (p=0.024 and p=0.005, respectively) and the last three months (p=0.013 and p=0.009, respectively), among the importance of religion and the lifetime use of alcohol, marijuana and cocaine (p <0.001, p <0.001 and p = 0.024, respectively) and the use of only marijuana in the last three months (p <0.001) and among the use of marijuana in the last three months and the year of graduation (p=0.003). Regarding age, the results showed a significant difference only between the groups that reported not to use alcohol in life (p=0.037). Conclusion: the investigated university students presented a prevalence of use in their lifetime and in the last three months of marijuana and cocaine greater among men, but not for alcohol. The importance of religion was negatively associated with the use of investigated drugs. The results can provide important subsidies for the structuring of preventive measures for abuse of psychoactive substances between university students and the need for new investigations that cover the subject.

Background: Trichomoniasis is known as a common venereal disease. It is estimated that 180 million people in the world are infected with this disease. The present study was conducted to estimate the prevalence of (Trichomonas vaginalis) T. vaginalis among women who were referred to the central laboratory in Ilam. Methods: In this cross-sectional study, 481 women with suspicious symptoms of trichomoniasis were selected during the first six months of 2015 in the central laboratory and Shahid Mostafa laboratory in Ilam, Iran. All patients were referred to the labs by gynecologists. Sterile swabs were used to collect direct smears. The results and questionnaire data were entered into SPSS version 16 and were analyzed using chi-square test and Fisher's exact test. Results: Direct smear of T. vaginalis demonstrated seven positive cases (1.5%). The highest and the lowest percentages of T. vaginalis infection in women were related to the 45-50 and 20-30 years age groups, respectively. Illiterate women had the highest percentage of infection. No significant relationship was found between the level of education and trichomoniasis infection in women (p = 0.085). The highest infection rate was associated with the use of ectopic contraceptive methods (condoms). Conclusion: The prevalence of T. vaginalis was low among women in Ilam but was high among women who have used tubal ligation and condom to prevent pregnancy. Therefore, more attention is required from healthcare centers for appropriate education to women about the proper use of protective equipment.

Prevalence studies on oral conditions affecting children are rare worldwide, and none of them was conducted in in Erbil/Kurdistan region/Iraq. The aims in the this study were to determine the prevalence and distribution of oral conditions which include both lesions and normal variations in group of patients referred to a main, public specialized poly clinics dental center. A prospective cross-sectional study was performed, the including data collected were age, gender, and site of a condition. The examination of the patients was performed under standardized conditions; using artificial light, disposable gloves, retractors, and mirror with sterile gauze to hold tip of the tongue. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) version 22; Fisher’s exact test; and Chi-square test. A sample of 520 children, aged range (0–13) years included in this study, 265 (51.0%) were males and 255 (49.0%) were females, divided into three age groups; 100 (19.2%) were <5 years, 274 (52.7%) were 5–9 years, and 146 (28.1%) were 10–13 years. The prevalence of oral conditions was significantly higher in 5–9 years (52.7%). The most commonly clinically diagnosed oral conditions were fissure tongue (13.1%), followed by gingivitis (9.0%) and dentoalveolar sinus (8.3%). As a first study in this age group in Erbil/Kurdistan region/Iraq, oral conditions are relatively common in the sample examined; dentist and dental practitioner should be aware for their recognition and referral for management.

Background: The child feed in the first two years of life is of fundamental importance for a healthy growth and development. Aims: To verify the association between food consumption indicators and overweight in children under the age of two, followed up by primary care health professionals. Methods: A cross-sectional study was conducted on 232 children assisted by primary care. A structured questionnaire was used with questions on sociodemographic data of mothers or guardians and food intake and anthropometric data of children. The analysis of the association between excess weight and food intake indicators was performed using the Pearson’s chi-square test (χ2) and Fisher’s exact test (f ˂ 5). Results: Regarding food intake in children under 6 months of age, 35.1% of the children were exclusively breastfed. Among children at the age of 6 to 23 months: 66.3% were on continued breastfeeding; 16.7% consumed adequate foods at the age of 6 to 8 months; 90.4% consumed foods that belonged to the six food groups; 76.3% consumed food at the minimum frequency and with adequate consistency; 88.9% consumed iron-rich and vitamin A-rich foods, and 59.3% consumed ultra-processed foods. Regarding nutritional status, 24.5% of the children were overweight. Conclusion: There was no statistically significant association between overweight and food consumption indicators among the surveyed children. However, exclusive breastfeeding was below the recommended level, a low percentage of the introduction of complementary foods at the appropriate age and high consumption of ultra-processed foods reveal the need to improve the assistance provided by primary care to this group.

ABSTRACT Purpose Verify the position of lips and tongue at rest in newborns with and without ankyloglossia. Methods Cross-sectional study, carried out with 130 newborns in University Hospital. Data collection was performed by the researcher and speech-language pathologists from the Hospital. Information on gestational age, sex, weight, height and days of life was collected. The position of the lips and tongue at rest was evaluated through visual inspection with the newborns asleep. After the newborns were awakened, Neonatal Screening of the validated Protocol for the evaluation of the lingual frenulum for infants was performed to detect the alteration of the lingual frenulum. The data obtained were described and submitted to statistical analysis using the Chi-Square test to verify the association between the position of the lips with the tongue and to compare the position of the lips and tongue with and without ankyloglossia. The Mann-Whitney test was used to verify the behavior of the variables the differed between newborns with and without ankyloglossia. The significance level of 5% was adopted. Results When comparing the data, a significant difference was found between: weight and height with and without ankyloglossia; position of lips and tongue. An association between the position of the tongue and lips with and without ankyloglossia was also found. Conclusion Newborns without alteration of the lingual frenulum have a tendency to remain with their lips closed and their tongue elevated during rest and newborns with ankyloglossia have a tendency to keep their lips parted and their tongue low during rest.

ABSTRACT Purpose: to describe the changes in speech and dental occlusion in children with cleft lip and palate and verify their association with each other and with the time of primary plastic surgeries. Methods: a cross-sectional study with collected data on the subjects’ identification, age at the time of primary surgeries, and clinical assessment of speech and dental occlusion. The chi-square test, Fisher's exact test, and t-test were used to verify the associations between the variables at the 5% significance level (p < 0.05). Results: the sample comprised 11 children aged 6 to 10 years, most of whom were males, self-reported white, with trans-incisive foramen cleft, predominantly on the left side. The mean age at lip repair surgery was 6 months, and 13 months at palatoplasty. Among the main dental occlusion changes, posterior and anterior crossbite stood out. All the subjects presented changed speech, with a prevalence of cases with dentoalveolar and palatine deformities, followed by passive and active changes. Subjects with anterior crossbite tended to have undergone primary lip repair surgery at a mean of four months earlier than the subjects without anterior crossbite. Conclusions: the associations between speech and dental occlusion changes, and between these and the time of primary plastic surgeries were not statistically significant. Even though it is known that early lip repair surgery is ideal to favor oral functions and aesthetics, the results revealed a tendency towards anterior crossbite, in these subjects.

Background: An attractive smile is often attributed to incisor alignment and proclined or retroclined incisors could contribute to a less aesthetic smile. Objectives: This study was aimed to evaluate the maxillary central incisor crown inclination, crown angulation and tooth size variation in aesthetic and unattractive smiles. Methods: This study was conducted among 100 females (equally divided into aesthetic and unaesthetic smile groups), aged between15 - 25 years, with Angle’s Class I normal occlusion and balanced profiles. Variations in maxillary central incisor crown inclination and angulation were measured on lateral cephalograms, photographs and the study models of the subjects. Variations in tooth morphology were also evaluated by measuring crown height and width in both groups. Mann-Whitney U test was performed to evaluate the difference between the aesthetic and unaesthetic smiles. P < 0.05 was considered as significant. Results: This study showed that incisor angulation was significantly higher in the unaesthetic group compared to the aesthetic group (P < 0.001). However, there was no statistically significant difference for the incisor inclination relative to the Palatal Plane between the aesthetic and unaesthetic smile groups (P = 0.086). In addition, there were significant differences between the aesthetic and the non-aesthetic groups regarding the central incisor height (P < 0.05). Conclusions: The findings of this study indicate that the possible variations in aesthetics are related to the ethnic elements that are associated with differences in crown angulations, as well as tooth size.

A cross sectional study was conducted in Eastern and Western parts of Chitwan district from November 2015 to April, 2016  in two parts, the social study followed by biological to determine and compare the prevalence, distribution of antibodies, and level of awareness of farmers  against Brucella abortus in cattle of the two regions of same district. Altogether blood samples of 92 cattle were taken for detection of Brucella antibodies by using RBPT test and the positive samples were further retested by Indirect ELISA test through ID Vet iELISA kit 2016. The samples which showed positive on both tests were confirmed as seropositive. Chi -square test and Fisher Exact test was used to find out the association between various variables. The result showed that 14.13% (13/92) and 10.86% (10/92) sample were positive by RBPT and iELISA test respectively. There was no significant prevalence differences (p>0.05) on location, age group, breed type, and method of service (artificial and natural) used in cattle. Comparing abortion with prevalence of Brucellosis, there was significant differences (p<0.05) in the result of both RBPT and iELISA test. Inferring from this result, there is association between the abortion and occurrence of Brucellosis. The higher significant prevalence differences (p<0.01) was according to the time of abortion where higher seropositivity was obtained in the cattle aborted on 5-7th month of pregnancy and cattle of 3rd parity. The study showed the existence of Brucellosis in Chitwan district with no adoption of any preventive measures against this disease, so here is current need of the strategies for its prevention and control in order to mitigate such overwhelming situation.Int J Appl Sci Biotechnol, Vol 4(3): 365-371

Background: Global Health Estimates 2015 has shown the stroke as second leading global cause of death and 3rd leading global cause for DALYs for year 2015. The objectives of this study were to determine the frequency, distribution and determinants of hypertension in adult stroke population of D.I.Khan Division, Pakistan. Materials & Methods: This cross-sectional study was conducted in Department of Community Medicine, Gomal Medical College, D.I.Khan, Pakistan from February 1, 2017 to April 30, 2017. A sample 217 was selected with margin of error 5.59%, 90%CL and 50% prevalence of hypertension in 200,000 adults at risk of stroke population through consecutive sampling. All indoor adult patients of stroke were eligible. Sex, age groups, and residence and presence of hypertension were variables. Frequency and distribution of hypertension were analyzed by count and percentage. Hypotheses for distribution were substantiated by chi-square goodness-of-fit and of association by chi-square test of association. Results: Out of 217 patients with stroke, 123 (56.7%) were men and 94 (43.3%) were women, 86 (39.6%) were≤60 years and 131 (60.4%) were>60 years, and 105 (48.4%) were urban and 112 (51.6%) were rural. Frequency of hypertension was 132/217 (60.83%). Out of 132 patients with hypertension, men were 74 (34.10%), women 58 (26.73%), age group≤60 years 46 (21.20%), >60 years 86 (39.63%), urban 72 (33.18%) and rural 60 (27.65%). Presence of hypertension was associated to residence (p=.023) but not to sex (p=.817) and age groups (p=.072). Conclusion: Frequency of hypertension in adult stroke population of D.I.Khan Division, Pakistan was found to be similar as expected. Frequency was more in men, in older age group (of>60years) and in urban population. The presence of hypertension in adult stroke population of D.I.Khan Division was associated to residence but not to sex and age groups.

Background: Construction sector is a thriving industry which comprises most of the unorganized workers and providing widespread opportunities for employment of most of the poorest and marginalized sections of society in India. The workers are more susceptible to various occupational hazards due to working conditions in dusty environment. This study is proposed to identify the morbidity pattern, availability and usage of safety measures, health care seeking behaviour and health care facilities at the quarry site.Methods: A cross sectional study was conducted among the stone quarry workers of Maduranthakam area in Kancheepuram district from February 2018 to May 2018. The sample size was calculated as 94 and five quarries were selected randomly. The study tool was interview based semi structured questionnaire and clinical examination. Appropriate descriptive and inferential statistics like Chi square test, Fischer’s exact test was done to determine significant association (p<0.05).Results: The common morbidities among the participants were abdominal conditions (54%), injuries (34%) and musculoskeletal disorders (27%). One in five individuals had respiratory problems and those with breathing difficulty had decreased peak expiratory flow rate. Usage of personal protective equipments is low and about 63.8% of them were using government health care facilities.Conclusions: Increasing demand for stone and aggregates has led to extensive stone quarrying operations. Awareness and enforcement of personal protective equipment, vaccination against diseases like tetanus, periodic health check- ups should be enforced for people working in quarries.
