The aim of this study was to determine whether or not the analysis of maximal intercuspation, protrusive and laterotrusive movements requires an additional digital method of occlusal diagnosis using the T-Scan™ Novus™ device (TekScan). In this observational study, we retrospectively examined a number of 10 subjects which were divided into 2 groups: the 1st group involved patients with intact dental arches and the 2nd group with patients that had received implant-supported restorations. The methods of analysis involved the calibrated articulating paper of 200 and 40 micrometers, and also the T-Scan™ Novus™ device (TekScan). The following data were collected: contact points in maximum intercuspation (functional and premature contacts), the pairs of teeth performing protrusion and right/left laterotrusion, active/passive interferences and premature contacts during protrusion and right/left laterotrusion. Descriptive statistics were obtained using the MedCalc Statistical Software version 19.2.6 (MedCalc Soft-ware bv, Ostend, Belgium) and Microsoft Excel for MAC 2011. It was tested if a statistically significant difference existed between the diagnostic methods regarding the number of contact points. The T test for independent samples without the assumption of equal variances and the Mann-Whitney test was used (to which we reported the medians of the 2 subgroups and the P value adjusted for equalities) and also the magnitude of association using the Chi-square test (p value) was measured. Also it was studied the correlation between the number of premature contacts and the number of contact points, respectively, obtained by each diagnostic method, and we expressed the results through the Spearman correlation coefficient. The analysis of the maximum intercuspation, of the protrusive and the laterotrusive movements has shown comparable results using the two examination methods. There were no statistically significant differences between the two methods of analyzing dental occlusion.

Introduction: The study aimed to evaluate the knowledge and awareness of orthodontics, a specialty of dentistry,amongst Medical Students. Materials and Method: A sample of 550 students (279 female, 226 male aged between 18 and 36 years) were attented.Of the subjects, 58.6% (n = 296) were preclinical students, while 41.4% (n = 209) were clinical students. The students were informed about the questionnaire and asked to fill in the questionnaire forms. For the comparison of data between groups (gender, level of education), the chi-square test was used. A chi-square test was used for statistical evaluation and the p-value < 0.05 was considered statistically significant. Result: 385 students (76.2%) had heard the term orthodontics although 41.2% of the subjects knew that orthodonticswas concerned with malocclusions and their treatment. The question about treatment procedures was answeredas scaling by 35.8%, tooth polishing by 40%, tooth aligning by 89.9% of the students. The percentage of knowingorthodontics to be related to tooth aligning showed a significant difference between female and male (p = 0.006), andpreclinical and clinical students (p = 0.033). Of the participants, 42.8% thought that dentures, 83% brackets, 78.8% ofremovable appliances were used by orthodontists. Conclusion: Our results have shown that medical students should have more information about orthodontics, aspecialty of dentistry.

Background: The SSRIs being used as 1st line therapy in treatment of depression have delayed therapeutic effect which makes the patient vulnerable to an increased risk of suicide and decreased adherence to the treatment and will prematurely discontinue the therapy. The present study was conducted to evaluate if low dose mirtazapine-escitalopram combination therapy has any add on benefit over monotherapy with escitalopram.Methods: In a single-centered, comparative study involving patients with depression attending the out-patient after screening and exclusion, 60 eligible patients were randomly assigned to receive tablet mirtazapine 7.5 mg plus tablet escitalopram 10 mg intervention or tablet escitalopram 10 mg plus placebo intervention in a double-blind 6-week treatment phase. The primary outcome measure was the change in the 17-item Hamilton Depression Rating Scale (HDRS) and Montgomery-Asberg Depression Rating Scale (MADRS) score from baseline. Participants were evaluated at baseline, 1st, 2nd,4th and 6th week. Results were analyzed using Chi-Square test for adverse effects and independent t-test analysis for efficacy parameter.Results: In the analysis of results at 6th week the numbers of patients achieved remission in mirtazapine group are more with a p-value of 0.018 which is significant and the numbers of responders in mirtazapine group are also more which is statistically significant on chi-square test. There is no significant difference was observed between the two groups with reference to occurrence of adverse effect.Conclusions: Adding low dose mirtazapine has an added benefit in terms of efficacy and getting remission early with more number of responders in the treatment of major depression.

The pandemic that began in late 2019, COVID-19, affects all patients, including cancer patients. Patients with cancer that continues to spread and  there is no other effective alternative treatment must undergo surgery so that cancer does not get worse. Given this problem, many health care centers have developed a protocol system in the form of a COVID-19-free surgical route. This study is a retrospective cohort study comparing the incidence of pulmonary complications in patients undergoing elective cancer surgery at dr. Moewardi Surakarta before and during the COVID-19 pandemic. The study sample was adult patients  aged ≥ 18 years which underwent elective surgical procedures with the aim of curative cancer starting before COVID-19 (March 2019-February 2020) until the time the COVID-19 pandemic emerged (March 2020 - February 2021). The data obtained were 768 patients. Of these patients, 384 were classified as having a COVID19-free operation route during the pandemic, and 384 others underwent elective surgery in the pre-pandemic period. Based on the Chi-Square test, a p-value of 0.850 was obtained (P>0.05) which shows that there is significant difference between cases of pulmonary complications in surgical patients before and after the pandemic who were carried out through the COVID-19-free protocol route. In conclusion, there is no significant change in effect of the covid-19 free operation path protocol on the incidence of lung complications in postoperative elective patients at dr. Moewardi Hospital Surakarta, although this patented and mandatory protocol can reduce cancer patients’ morbidity and mortality who undergoing elective surgery during a pandemic.

Abstract Lip print pattern (LPP) is unique to each individual. For decades, forensic experts have used LPP for personal identification to solve criminal cases. However, studies investigating ethnic variation in LPP are scanty. Our study wanted to investigate variation in LPP between two ethnic groups, Oraon tribals and Bengalee Hindus, residing in West Bengal, India. A total of 280 participants included 112 Oraons and168 Bengalee Hindus of both. Prints were taken using dark shaded lipstick and transparent cellophane tape and recorded into white A4 sheet. Prints were divided into four quadrants and examined by magnifying glass. For analysis of results, classification of Suzuki and Tsuchihashi was followed. A p value of 0.05 was considered to be statistically significant. It was observed that Type II pattern was dominant in first and second quadrants in both ethnic groups, irrespective of sex. Combination of Type II+III was found to be the most common pattern in males among both Oraons (16.2%) and Bengalee Hindus (12.2%) whereas in females Type II pattern (25.0%) among Oraons and Type III pattern among Bengalee Hindus (11.4%) was the most common. Chi square test showed statistically significant difference among females (p<0.05) and in third and fourth quadrants among males (p<0.01) of both ethnic groups. Our investigation clearly demonstrated sex and ethnic variations in LPP. Further studies are required to investigate ethnic variation in LPP among the various populations groups, both tribal as well as non-tribal, from different regions of India.

Abstractwas to assess efficacy of Tadalafil alone versus Tadalafil plus Pentoxifylline in the treatment of erectile dysfunction by using self administered IIEF-5 questionnaire.Two hundred and thirty seven patients presenting with ED at andrology OPD were evaluated for ED by a self administered IIEF (International Index of Erectile Function) questionnaire. Patients were systematically randomized by computer generated random table into two groups groups namely, group A: Tadalafil only group, group B: combination of Tadalafil + Pentoxifyl-line. All the patients were re-assessed by IIEF-5 questionnaire after 8 weeks of medical therapy. Statistical analysis was performed using student’s unpaired t-test, paired t-test, chi square test. p-value < 0.05 was considered statistically significant.Two hundred and thirty seven patients were included in the present study, in group A: 92 patients (78.6%) showed improvement in their IIEF score after 8 weeks of tadalafil treatment. While in group B, overall 104 patients(86.6%) showed improvement after combination of Tadalafil and Pentoxifylline. There was a statistically significant difference of percentage change in IIEF score was seen in group B (group A 90.7±15.2%, group B 95.6±13.4%; p value – 0.014). We found this difference even more statistically significant in patients with severe ED (group A 72.7±47.2%, group B 132.3±54.3%; p value – 0.000). There was no significant difference in between the two groups with regards to occur-rence of side effects.Both tadalafil and combination of Tadalafil + Pentoxifylline improve erectile function in patients of ED. Patients with severe ED showed much significant improvement in erectile function with combination therapy.

Academic Delay Of Gratification

The present study measured the partial (configural, metric and scalar) invariance of Academic Delay of Gratification Scale (ADOGS) for college students prepared by Hefer Bembenutty and Stuart Karabenick (1996), with respect to gender. 488 students (277 boys and 211 girls) from engineering, law, pharmacy, and education faculties of Sultan Ul Uloom Education Society, Hyderabad, were samples of the study. Confirmatory Factor Analysis framework was used to test the three invariance, one at a time, using SPSS AMOS Ver.23. This was done by constraining the factor structure, factor loadings and intercepts for the genders boys and girls simultaneously. The SPSS AMOS CFA test provided Chi-square value and degree of freedom for the unconstrained and the constrained structures. By comparing the difference in the Chi-square test p-value for a degree of freedom of the constrained factor structure with the unconstrained structure’s Chi-Square p-value and its degree of freedom using an excel sheet calculator of Chi-square test available on the Internet, the measurement invariance of the instrument was verified. The findings of the study reveal that the scale is configural and metric invariant, as there is no significant difference between constrained and unconstrained structures. However, the scale is not scalar invariant. The educational implications are discussed.

Background and Objectives: Estimation of dental age is based upon the rate of development and calcification of tooth buds and their progressive sequence of eruption in the oral cavity. The tooth calcification provides a valuable indicator of dental age and serves as an index of the maturation of the child. The aim of this study is to determine whether Body Mass Index (BMI) has association with dental maturation. Materials and Methods: A cross sectional study design was applied for the present study, 383 school children were participated in this study which nominated from Erbil city. For the sample to be representative the city was divided in to six geographic areas according to the municipalities, the samples randomly selected school children of 10 to 14 years old from both genders. The height and the weight of each participant had been recorded in the college of dentistry / Hawler Medical University in order to calculate the body mass index of the following the guidelines of centers of disease control (CDC) , at the same time an orthopantomography radiograph had been used to investigate the stage of the dental maturation using the Demirjian method, finally, the relationship between BMI and dental maturation were investigated using chi square test with P value of ≤ 0.05 was considered significant difference. Result: there was a statistically significant relationship between dental maturation and BMI. The majority (93.6%) of samples with under-mature dentition were under-weight at the same time. The vast majority (96%) of samples with mature dentition had normal BMI. In the same manner, majority (91.7%) of samples with over mature dentition were over-weight too. Chi square test was used to find out the association and P-value was 0.001 Conclusion: In conclusion, normal weight students have normal dental maturation, underweight students have under dental maturation and overweight or obese students have over dental maturation. Keywords: body mass index, Demirjian, Orthopantomography.

ABSTRACT Introduction Physical performance depends on a variety of biological and mechanical properties. These different phenotypes are related through the complex interaction between the environment and the individual genetic profile. The hypothesis is that there is a hereditary component that interferes in physical fitness. ACE stands out among the genes that may influence this response. Objectives The objective of this study is to analyze the polymorphism of the ACE gene in American football athletes. Methods: At the end of the study, the sample was composed of 45 male athletes and 72 non-athletes. DNA was extracted from the jugal mucosa. ACE polymorphisms were genotyped through polymerase chain reaction and analyzed using the electrophoresis process. To compare the frequency of genotypes between athletes and the control group, we used the Chi-square test. The association between the frequencies of alleles was verified through the 2X2 contingency tables analyzed using the Chi-square test with Yates correction. The type of study was diagnostic - Investigation of a diagnostic test, level of evidence II. A p-value of ≤0.05 was considered statistically significant for all the analyses. Results The results showed a greater frequency of the D allele in American football athletes when compared with non-athletes, and a significant difference in the genotypic distribution of the athletes being composed of a higher number of the DD genotype as compared to the control group. Conclusion The study provides evidence of the allelic and genotypic influence of ACE polymorphism in amateur American football players in Brazil. Level of evidence II; Investigation of a diagnostic test.
