The examination of static and dynamic occlusal relationship are important in orthodontic diagnosis. Thus, this study aims to analysis the difference of occlusal cant and favored chewing side. This is cross-sectional study of 70 healthy dental students Universitas Sumatera Utara with complete dentition and have no orthodontics treatment history. The position of tongue spatula across on occlusal of both first bicuspids to assess the existence and degree of the canting occlusal based on extra-oral photograph. The occlusal cant positive if it coincided to inter pupil as transversal references and sectioned with facial midline as a vertical reference more than 3º. A modified direct method- visual observation was done to assess the favored chewing side. A chi-square test with p level 0.05 in evaluation of the null hypothesis that states there was a difference of occlusal cant and favored chewing side in those subjects. From 36 subjects with cant occlusal positive, there were 26 subjects with and 10 subjects without favored chewing side. Then, from 34 subjects with cant occlusal negative, there were 14 subjects with and 20 subjects without favored chewing side. There was a significant difference (p=0.017) between occlusal cant and favored chewing side. Subjects with complete teeth showed that favored chewing side tendency of 3,714 more often had an occlusal cant positive compared to favored chewing side negative. In conclusion, the significant difference of occlusal cant and favored chewing side in subjects with complete dentition can be considered as a preliminary study in order to understand the complexity of development of mandibular asymmetry.

Objective: To determine the effect of maternal iron deficiency anemia on APGAR score of neonates at one minute.Patients and Methods: This cross-sectional study was conducted at Aziz Bhatti Shaheed Teaching Hospital Gujrat from January 2017 to November 2017. In total 380 patients (50% anemic and 50% non-anemic mothers) were included in study. Grouping into anemic and non-anemic groups was done, based on their hemoglobin level, MCV, MCH and ferritin levels. APGAR score at 1 minute was noted in neonates born to both groups. Data was analyzed using SPSS 20.0. Chi square test was applied to evaluate the difference of APGAR score.Results: Mean age in anemic was 27+4.6 years and in non-anemic 26+5.1 years. The mean hemoglobin among anemic was 8.9+2.1 g/dl and among non-anemic 12.3+1.2 g/dL. Mean MCV in non-anemic 85.7+3.8 fl, while among anemic was 62.4+4.1 fl Mean ferritin levels among anemic were 7.4+1.1 ng/ml. Neonates delivered by anemic mothers had mean APGAR score of 6.5+0.2 and those delivered to non-anemic had 8.7+0.5. The APGAR score of neonates delivered by anemic and non-anemic showed a significant difference (p-value 0.00). The relative risk of having low APGAR score of infant in anemic compared to non-anemic mothers was 29.00 (95% CI, 13.1798-63.8098) with p<0.0001.Conclusion: Maternal anemia is significantly associated with poor APGAR score in neonates.

Background The COVID-19 pandemic has caused lockdown situation impeding all educational institutions including dental colleges. The circumstance demanded online classes as the alternative strategy for continuation of education. Objective To assess current practice and perception about online education among faculties of dental colleges in Nepal. Method A cross-sectional study was conducted among 208 faculties of all dental colleges in Nepal. Data collection was done through structured online questionnaire comprising demographic information, practice and perception of the respondents towards online education. Descriptive statistics surveyed the frequency distribution and Chi-square test assessed the difference in perception among the faculties of different universities. Result The response rate was 74.3%. Faculties commonly used PowerPoint presentation (96.6%) on Zoom platform (83.3%) using laptop (94.7%) with Wi-Fi connection (91.8%). Majority of faculties had good or satisfactory access to internet (94.8%). The faculties believed that the online class environment was interactive (95.2%); but it was not effective (86.5%) as live classroom. Majority of the faculties (79.4%) felt tracking of students’ presence was difficult. There was no significant difference on perception towards online class among the faculties of Kathmandu University, Tribhuvan University and BP Koirala Institute Health Sciences at p < 0.05. Conclusion The COVID-19 pandemic has paved the way for e-learning in dental education in Nepal. Faculties agree to complete the theory syllabus and conduct sessional exams as an alternative during the lockdown period. However, they show strong reservations in carrying out practical/clinical simulations and university exams online. Training on e-learning and institutional strategy for online education is recommended.

Skeletal Asymmetry

ABSTRACT Introduction: Facial skeletal asymmetry is commonly found in humans and its main characteristic is menton deviation. The literature suggests that occlusal and masticatory problems arising from tooth absence could be related to the development of such asymmetries. Objective: The aim of this cross-sectional study was to estimate the prevalence of mandibular skeletal asymmetries and to investigate its association with posterior tooth absences. Methods: Tomographic images of 952 individuals aged from 18 to 75 years old were used. Asymmetry was the analyzed outcome, and it was categorized into three groups according to gnathion displacement in relation to the midsagittal plane (relative symmetry, moderate asymmetry, and severe asymmetry). Patients were sorted by the presence of all posterior teeth, unilateral posterior tooth absence, or bilateral posterior tooth absence. Chi-square test with a significance level of 5% was used to verify the association between posterior tooth absence and asymmetry. Results: Results show relative symmetry present in 55.3% of the sample, as well as the prevalence of 27.3% for moderate mandibular asymmetry and 17.4% for severe asymmetry. Moderate and severe mandibular asymmetries occurred in a higher proportion in patients with unilateral posterior tooth absence. However, there was no statistically significant difference between the analyzed groups (p = 0.691). Conclusions: In this study, mandibular asymmetries did not present any association with the absence of teeth on the posterior area of the arch.

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.

Objective: To determine the differences of self-perception of halitosis and oral hygiene practices among the medical and dental undergraduate students. Methodology: A cross-sectional study conducted over duration of 9 months amongst the medical and dental undergraduate students of Bahria University Medical and Dental College. The questionnaires were distributed to 298 students. Questionnaire employed for this study was adopted and modified from the study conducted by Khalid Almas et al. Descriptive statistics were checked by means of percentages and frequency for all variables. Chi-square test was applied to check significant difference among the responses given by the medical and dental undergraduate students. Results: The response rate for the survey was about 85%. 55% of dental and 17 % of medical students were able to smell their breath. About having examination by dentist about 73% of medical students agreed as compared to 53% of dental students. Both medical and dental students preferred having examination done by the dentist. For management of halitosis, dentist was preferred by 62% of the dental students, while 97% of the medical students did not agree. 62% of the dental students preferred using traditional medications, while 82% of the medical students preferred using self-medications for treatment. Conclusion: The results suggest that there is not a high level of agreement among dental and medical students concerning the detection and management of halitosis. Although large percent of the respondents claimed to be aware of dentistry, our findings revealed low level of knowledge and attitude to Dentistry by the medical undergraduate students. Efforts should be made towards closing this knowledge gap to attain effective oral health.

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.

Diastasis Recti (DR) is a common muscular condition often present during and after pregnancy. This cross-sectional correlational study investigated the prevalence of DR among pregnant and postpartum women. A total of 250 pregnant and postpartum women were recruited using convenience sampling technique from obstetrics and gynaecology department, Aminu Kano Teaching Hospital, Kano, Nigeria. Age, body mass, height, BMI, parity, trimester, duration of DR postpartum, location of DR and DR status was recorded for each participant. Presence of DR was confirmed using the finger width method. Descriptive statistics of mean, SD, percentage were used to describe the data and determine the prevalence. Inferential statistics of Pearson’s and Spearman’s correlation were used to analyse the relationship between prevalence of DR and age, parity and duration of DR postpartum. Chi square was computed to determine the difference in prevalence of DR across trimesters. The result of this study indicated high prevalence of DR in post-partum and pregnant women (84% and 64.7% respectively); the most common location of DR was at the umbilicus in both pregnant and postpartum women. Prevalence of DR was high among the multigravida; and a significant relationship was found between prevalence of DR and age and parity of participants. There was a significant difference in prevalence of DR across the trimesters. It can be concluded that prevalence of DR among pregnant and postpartum women is high; age and parity are determinants of DR prevalence. Evaluation of DR should be considered as routine assessment in both pregnant and postpartum women.

: An emergency can be encountered anytime and anywhere. Minimal knowledge about medical emergency and their etiology, primary protocol for management must be known to avoid potential consequences. Hence, the present study was undertaken to compare the knowledge, and ability to handle the medical emergencies among the dental students. A cross-sectional survey was conducted among 100 randomly selected dental students (post-graduate students and interns) comprising of two groups of students those who had underwent training and those who did not. The data obtained was analyzed using the SPSS for windows version 22.0 released 2013. Independent chi square test was used for comparison of responses and independent student t-test was used for the comparison of mean scores. The significance level was set at p&#60;0.001. : The average mean knowledge and ability score was 68% & 61.4% respectively among the participants. On further comparison of mean knowledge & ability scores between the participants with & without basic life support training, participants with BLS training showed better knowledge than those without training and the difference was statistically significant between the two groups (p&#60;0.001%). The study found deficiencies in the knowledge and ability of untrained graduates to deal with medical emergencies as compared to trained.

BACKGROUND: In Indonesia, a new behavior has been introduced in the community to prevent COVID-19 transmission following 3 months of the COVID-19 outbreak. The Ministry of Health, Republic of Indonesia, names this new concept as “the adaptation of new behavior.” However, preventive measures and health protocols encouraged by the government have not yet yielded a significant impact on reducing the COVID-19 positivity rate. This unsuccessful outcome indicates that infective circulation is still occurring caused by incompliant to the health protocol. AIM: This study aimed to measure community perceptions against COVID-19 at the individual level. METHODS: A cross-sectional study with a total of 1687 respondents was performed. Questionnaires distributed thru sharing online links which contain questions on perception of vulnerability and severity of COVID-19. Chi-square test used in analysis to determine the difference in perception with respondents’ behavior. RESULTS: A total of 81.7% of respondents who had a perception of “susceptible to contract” performed behavior suited to recommendations and 81.2% study population had a perception of “COVID-19 is severe” executed behavior suited to the recommendation. CONCLUSION: This study demonstrated the establishment of government recommendations for COVID-19 infection did not guarantee the actual health practice/behavior in the community. The existing misconception of the perspective of seriousness/severity and susceptibility would prevent the country from flattening the curve.

Background: COVID-19 is a serious pandemic. However, no studies worldwide have assessed the knowledge of any healthcare workers, including dentists, towards COVID-19. Objectives: Given the importance of Iran as an epicenter of this disease, this preliminary study assessed the knowledge of dentists, dental students, and dental specialists towards COVID-19. Methods: In this cross-sectional study, a questionnaire with 23 questions (three regarding sources of information and 20 regarding knowledge) was developed through a pilot study. It was distributed electronically to dental professions/students, 778 of whom completed it. Factors associated with knowledge were assessed using the chi-square test in SPSS (α = 0.05). Results: Above 70% of the responders answered correctly to all questions, except for six more technical questions, including handwashing-related questions. Age, specialization, and attendance at lectures and meetings did not play a role in grasping accurate information (all P values > 0.1). Men had poorer information (P = 0.014), and the sources of information were mostly official websites and social networks (P = 0.000). Conclusions: Knowledge of dentists, dental students, and specialists towards SARS-CoV-2 is generally good, except in the case of more technical questions that need more education (especially regarding handwashing).
