Objectives: To test the hypothesis that there is no difference between adults with Class I crowded (CICR) and Class I normal (CIN) occlusions with respect to  width of the maxillary and mandibular arches and gender comparisons. Materials and Method: In this cross sectional study, 52 pairs of study models were selected from the patients and students of the Orthodontics and Dentofacial Orthopedics Department of Dhaka Dental Collage and Hospital and were divided into two groups, 27 pair of dental casts with normal occlusion, 25 pair of dental casts with Class I crowded malocclusion including equal males and female samples. Results: The result of this study evaluated two study groups (Normal occlusion and Class I crowded ). Between different arch dimension maxillary arch widths were found to have significantly smaller in Class I crowded malocclusion compared with Normal Class I occlusion. Conclusion: In conclusion, the hypothesis was partially rejected by the finding of the study. Ban J Orthod & Dentofac Orthop, April 2017; Vol-7 (1-2), P.1-5

Aims: A descriptive type of cross-sectional study was conducted at the department of Orthodontics & Dentofacial Orthopedics of Dhaka Dental College & Hospital, Dhaka, Bangladesh during January 2010 to December 2012. The aim of the study was to test the hypothesis that there were no differences between adults with class I crowded, class III and class I normal occlusions in respect to width of the maxillary and mandibular arches and gender comparisons. Materials and Methods: In this study, 82 pairs of study models were selected from the patients and students of the Department of Orthodontics and Dentofacial Orthopedics at Dhaka Dental College and Hospital and were divided into three groups. Twenty seven (27) pairs of dental casts with normal occlusion, 25 pairs with class I crowded and another 30 pairs with class III malocclusions that included almost equal numbers of male and female samples. Results: Among different arch dimensions, maxillary arch widths were found to have significantly smaller in class I crowded and class III malocclusions compared to normal class I occlusion. Conclusion: The hypothesis was partially rejected by the findings of the study. It may be suggested that Orthodontist who is aware of these differences in arch dimension will be beneficial to diagnose and make planning of treatment of orthodontic cases more accurately.

Treatment Changes

Background: The orthodontic treatment should aim to maintain the inter-canine and inter-molar width to that of the pre-treatment values. The study was conducted with objective to evaluate arch width changes in Class I and Class II patients treated with fixed orthodontics. Methods: This was a hospital-based cross-sectional study with two study groups. The first group included patients with Class I malocclusion, treated with four first premolar extractions and the second group included patients with Class II Div 1 malocclusion, treated with upper two first premolar extractions. The inter-canine and inter-molar width of the pre and post-treatment study model were measured. To compare the changes observed amongst two groups, independent samples t-test was performed. A paired sample t-test was used to evaluate the treatment changes within each group. Results: There was significant increase in inter-canine width in both maxillary and mandibular arches in both the groups. In Class I extraction group there was significant decrease in the inter-molar width in both maxillary and mandibular arches. The Class II Div1 maxillary extraction group also showed significant increase in inter-canine width in both maxillary and mandibular arches. In the same group there was decrease in post treatment Methods: This was a hospital-based cross-sectional study with two study groups.

Elevated serum Transforming growth factor-beta1 (TGF-beta1) levels have been linked to tissue fibrosis including chronic kidney disease. Objectives: (1) Investigate serum TGF-beta1 levels in healthy adult people and (2) Examined the relation between serum TGF-beta1 level and gender, age, body mass index (BMI). Method: A cross-sectional study. TGF-beta1 were quantified by ELISA. Results: Levels of serum TGF-beta1 in healthy people were 13,45 ± 7,17 ng/mL mL (0,59 - 33,10 ng/mL). There are no difference of serum TGF-beta1 levels between men and women, between the age groups (<40 years, 40 to < 60 years and ≥ 60 years), between BMI groups < 23 and BMI group ≥ 23. Key words: TGF-beta1, healthy people

Introduction: Various forms of malocclusion are a matter of serious concern in Nepalese population. This study was carried out to understand the prevalence of malocclusion among the school children of Biratnagar. The objective of this research is to find out the prevalence of malocclusion of children from different schools of Biratnagar visiting the Pedodontics and Orthodontics department of Nobel Medical College and Teaching Hospital, Biratnagar. Materials and Method: A descriptive cross sectional study method was used in this research. Data was collected by using direct observation of the subjects and occlusal assessment was done according to Angle’s classification and Dewey’s modification types of class I, class II and class III malocclusion. Result: Subjects with normal occlusion was found to be 39 % and with malocclusion was found to be 61%. Among them, class I malocclusion (60%) and angles class II div I subjects (88.33%) were in majority of the total study population.

Background: Dirofilaria immitis is one of the most important parasites of the circulatory system of dogs that causes severe cardiovascular events in the animal and it is reported to be the most common nematode in humans and dogs from many parts of Iran. Methods: In order to investigate the presence of Dirofilaria immitis infection in Tabriz, Iran, a cross-sectional study was performed on 200 owned and stray dogs. The blood samples were analyzed using Knott method. The prevalence of D. immitis infection was reported to be 15% in owned dogs. Results: The highest levels of infection were reported in dogs less than one year of age and the lowest in dogs aged over 9 years. In a statistical survey, there was a significant relationship between infection and gender. Conclusion: According to the findings of this study, due to the presence of D. immitis infection in this region, the need for a more comprehensive examination and control of the infection in this region is emphasized.

Aim: The present study aimed to assess anxiety fear and awareness among dentists working during the current Corona Virus (COVID-19) outbreak. Materials and Methods: An online questionnaire was distributed using Google Forums in March 2020. A total of 249 participants from different cities across Pakistan participated and submitted the results. The data were entered in IBM SPSS Statistics, version 22 (IBM Corp) for statistical analysis. Results: No significant relationship (P< 0.06)between the participant's responses and gender or their education was established in this study. However, increased anxiety in Pakistani dentists because ofCOVID-19 was seen; 90.0%. A large number(86.7%) of the professionals seemed to be familiar with the revised CDC and WHO guidelines in regards to cross-infection for Coronavirusin dental procedures. However the majority 66.3% reported that they did not use rubber dam isolation in their treatments and only 45% had high-volume suction in their practices to use during treatments. Conclusion: Dentists all around Pakistan are anxious and fearful at work because of the pandemic. It is absolutely vital that only emergency dental procedures are given priority in regards to treatments while all elective procedures should be deferred till the pandemic is under control. Clinical Significance: It is important to identify the challenges the COVID-19 pandemic has presented to all dental professionals.
