Mineral trioxide aggregates (MTA) has been considered one of the most effective pulpotomy materials as it induces the formation of dentine at a greater rate with superior structural integrity, minimal inflammation and nominal hyperplasia. Portland cement (PC), posing the principal chemical elements with similar mechanisms of action, physical properties and biocompatibility like MTA, may be considered as effective alternative for the same. So, the objective of the study was to compare the clinical and radiographic outcome of Portland cement and mineral trioxide aggregates as pulpotomy material in primary teeth. A total of 40 patients having deep carious primary tooth with mild thermal sensitivity were enrolled in this study. Pulpotomy 20 patients were treated with Portland cement and the remaining 20 patients were treated with mineral trioxide aggregates, those considered as group A and group B respectively. Then, clinical and radiological examinations were performed at 3, 6 and 12 months interval to investigate the incidence of postoperative pain, swelling, dentinal bridge formation and root resorption. After a period of one year, a total of 60.0% teeth treated by Portland Cement and 50.0% teeth treated by MTA group came out successfully both clinically and radiographically. All these treated teeth that came out successful remained vital having no pain clinically along with radiological evidence of dentin bridge formation and absence of internal resorption. The difference between the tested groups was not statistically significant (p>0.05). It can be considered that Portland cement (PC) can also be used as successful pulpotomy material as an effective and economic substitute of MTA.

Foot Fractures

Most frequent trauma to primary dentitions are injures to the supporting tissue i.e. luxations, but root fractures are relatively uncommon. The difference in the trauma pattern favoring luxation rather than fracture has been found to be typical for the primary dentition, since the elasticity of the alveolar bone surrounding the primary teeth is high and primary tooth held in alveolar socket is less strong. Incidence of foot fractures increases at the age of 3-4 years where physiologic root resorption has begun, thereweakening the root. Traumatic injuries to the primary dentition present special problems and the management is often different as compared with the permanent dentition. Because of potential sequelae of trauma to primary teeth, a treatment method that minimizes any additional risks of further damage to the permanent successors should be selected. The report presents a case of 3.5 year-old boy after traumatic injury – extrusion of tooth 51, which required surgical treatment, and apical third horizontal root fracture of tooth 61 treated conservatively. Written consent from subject’s parents/subject’s legal guardians was obtained. Root-fractured primary tooth has been followed clinically and radiographically for 3.5 year, till advanced root resorption. Presented case and cases described in cited literature demonstrate that conservative treatment of root-fractured primary teeth is a favorable method of the treatment that allows the teeth to function naturally until the term of physiological resorption and exfoliation.

Background: Pulpotomy is measured as one of the most worldwide accepted favourable clinical procedure for the treatment of deciduous tooth with reversible pulpitis with carious destruction of tooth tissue. Objectives: To evaluate the clinical and radio-graphical findings of primary tooth with reversible pulpitis by Biodentine and Calcium Hydroxide as pulpotomy material. Study Design: Randomized comparative study. Study place and period: Conservative Dentistry & endodontics department of Bangabandhu Sheikh Mujib Medical University, Dhaka, September 2013 to September 2014. Study Population: The study population comprised of patients having primary tooth with reversible pulpitis irrespective of sex. Methods/Procedure: According to inclusion and exclusion criteria, out of 100 primary teeth 50 teeth were treated with Biodentine (Group-A) and the remaining 50 teeth were treated with Ca(OH)2 (Group-B). Clinical and radiographic follow up examination were done at 3months,6 months and 12 months’ interval to evaluate the rate of postoperative pain, swelling and periapical radiolucency. Statistical package for Social Science (SPSS) version 17 was used to analyze the collected data Main outcomes measures (s): 01. Pain 02. Dentinal bridge 03. Root resorption Results: At 3 months observation period, Biodentine and Ca(OH)2 pulptomy of primary teeth showed 100% success rate in treating teeth with reversible pulpitis; neither pain nor swelling or radiographic sign of resorption was observed. At 6 and 12 months following the completion of treatment except in two case in group A and four case in group B in observation period, there results were similar to that of 3 months. Two Biodentine (4%) and four Ca(OH)2 (8%) therapy reported pain, swelling. There was no statistical difference between the two group (p>0.05). Conclusion: So, we can say that clinical and radiographic end result of Biodentine is better than Ca(OH)2 as a pulpotomy material in mature primary tooth with reversible pulpitis. Update Dent.

Background: Scabies is one of the most common skin diseases in our country. It is caused by the mite Sarcoptes scabiei var hominis, which is an ecto-parasite infesting the epidermis. Scabies is highly contagious. Prevalence is high in congested or densely populated areas. Individuals with close contact with an affected person should be treated with scabicidal which is available in both oral and topical formulations. The only oral but highly effective scabicidal known to date is Ivermectin. Amongst topical preparations, Permethrin 5 % cream is the treatment of choice. Objective: To evaluate the efficacy & safety of oral Ivermectin compared to topical Permethrin in the treatment of scabies. Methodology: This prospective, non-randomized study was conducted at the out-patient department of Dermatology and Venereology of Shaheed Suhrawardy Medical College & Hospital over a period of 6 months, from August 2016 to January 2017. The study population consisted of one hundred patients having scabies, enrolled according to inclusion criteria. They were divided into two groups. group A was subjected to oral Ivermectin and the group B to Permethrin 5% cream. Patients were followed up on day 7 and 14 for assessment of efficacy and safety. Result: The mean scoring with SD in group A (Ivermectin) and group B (Permethrin) were 8.26 ± 2.22 and 7.59 ± 2.01 respectively at the time of observation. The difference between the mean score of the two group is not significant (p=0.117) the mean scoring with SD in group A and group B were 4.54 ± 2.05 and 1.64 ± 1.84 respectively at 7thdays. The difference between the mean score of the two group is significant (p<0.001). The mean scoring with SD in group A and group B were 2.68± 2.35 and .36± 1.10 respectively at 14th day difference between the mean score of the group is significant (p<0.001). Conclusion: Topical application of permethrin 5% cream is more effective and safer than oral Ivermectin in the treatment of scabies. TAJ 2020; 33(1): 41-47

Relevance. To study the incidence of different types of resorption of multirooted primary teeth, to specify indications for deciduous molar extraction to prevent eruption abnormalities of permanent posterior teeth in mixed dentition.Materials and methods. Root resorption of 375 multirooted primary teeth (166 first primary molars and 209 second primary molars) was studied on panoramic X-rays of 60 children (30 girls and 30 boys) aged between 7 and 15. Illustrated classification by T.F. Vinogradova (1967) improved by authors was used to determine type and degree of root resorption of multi-rooted primary teeth. Received data were described with absolute values of number of cases and percentage. Chi-square was used to detect differences in sign incidence rate between groups, p<0.05 was considered statistically significant.Results. There were no statistically significant gender differences (p>0,05) in type and degree of root resorption of multirooted primary teeth. Type A resorption prevailed and constituted 53.3% of all primary molars. Disturbances in root resorption of multirooted primary teeth in mixed dentition were related to health condition of primary teeth. Transition of even resorption to unven was considered a risk factor of delayed eruption and aberrant position of permanent teeth, and indication for extraction of a primary molar in question. Conclusions. 1) Even root resorption (type A) was detected in 53.3% of primary molars in mixed dentition by orthopantomography. 2) Transition from even resorption of primary molar roots to uneven resorption was associated with eruption deviations and delayed premolar eruption. 3) Timely extraction of primary molars with uneven root resorption facilitated correct eruption of premolars and increased effectiveness of secondary prevention of malocclusion in children.

Abstract In order to quantitatively assess the effect of sample storage conditions on the body burden analysis of organic contaminants, a comparative analysis was carried out on the unionid mussel Elliptic complanata. The mussels were divided into two groups, each with distinct storage conditions, while Group A was kept in the freezer at −20°C, Group B was kept in the refrigerator for five days at 5°C. All the compounds present in the control were also present in Group B samples. Analysis of the organic contaminants in each of these two groups showed that for total PCB concentrations, the two treatments were not significantly different; however when compared individually 6 of the 13 PCB congeners showed significant differences. The observed differences were relatively small for individual PCB congeners (7.1 to 15.3%), higher for chlorobenzenes (10.5 to 36.4%), and yet higher for HCE (44.1%); the difference for HCE, although large is nevertheless not significant, even if only marginally so.

Seventy primary molar teeth, carious exposed, symptom free, without any sign of root resorption in children aged from 3 to 6 years (main age 4.3yr) were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 35 teeth) and formocresol solution (five minute procedure of Buckley's formula for next 35 teeth) have been used as pulpotomy agents. In both groups, pulp stumps were covered with zinc-oxide eugenol paste. Permanent restorations were stainless steel crowns. Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment. Our results within this period revealed 100% clinical success rate in both groups. Radiographic success rate was in both groups 97.2%, while in 2.8% cases has shown internal root resorption. On the basis of these results, we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment.

Without having a reaction time, the pandemic has caused an unprecedented transformation in universities around the world, leading to a revolution from structured models anchored in the conception of transmission of training towards a teaching approach-learning saved thanks to the incorporation of technology. This study aims to verify whether the pandemic situation has influenced the digital competence self-perception of students. Comparing two groups during the academic years 2019/2020 and 2020/2021, the instrument used is the questionnaire for digital competence “DigCompEdu Check-In” for future teachers. After the educational intervention, group A (before COVID-19) presented higher self-perceptions of competence than group B (during COVID-19); the pandemic situation caused by COVID-19 has negatively influenced students’ self-perception of their digital skills in the pretest in the different dimensions under study. Before receiving the training, the group that did not experience the pandemic enjoyed a higher self-perception of their competencies than the group that experienced the pandemic. The data obtained indicate that the difference exists, and that it is statistically significant, and may be a consequence of the clear relationship between self-perception and the way in which students face reality through their personal and subjective vision.

Effect Of Age

Objectives: The main goal of this research was to determine the differences between the values of intraocular pressure (IOP) in the supine and sitting positions, and to assess the effect of age and cardiovascular parameters. Methods: Seventy-two healthy adults were enrolled and classified into age groups: 20–30 years (group A), 31–40 years (group B), and 41–71 years (group C). Corneal biometry and cardiovascular parameters, such as heart rate (HR), were measured. IOP measurements were taken in the sitting position (IOPS) and in the supine position (IOPL) using the iCare® Pro tonometer. Results: A significant difference between the IOPS and IOPL in the entire cohort was found ( p < 0.001). Regarding the age subgroups, a significant difference ( p < 0.001) between the IOPS and IOPL was obtained in group A (2.6 ± 1.6 mmHg) and group C (1.5 ± 1.3 mmHg). There were no significant differences in the IOPS between groups. The highest IOP values were obtained for group A. The correlations between HR and IOPS are statistically significant for group A and group B, and for HR and IOPL-S for group B only. Multivariate analysis showed that HR has a significant influence on the difference in IOP in the two body positions. Conclusion: A statistically significant difference between the effect of age and the values of IOPS and IOPL was shown. Cardiovascular parameters showed some relevant statistical dependencies, but with a rather marginal significance in young people. The influence of body position for the measurement of IOP for healthy subjects does not seem to matter, despite the fact that there are some dependencies that are statistically significant.

Background: Tonsillectomy is one of the most common surgical procedures performed worldwide by otorhinolaryngologists for different indications. Tonsillectomy is often performed as day-case surgery, which increases the demands of a satisfactory postoperative pain control and a low risk of early postoperative bleeding. Objective: The aim of the study was to compare the Monopolar diathermy and Dissection methods of tonsillectomy and evaluate their advantages and disadvantages during surgery, convalescence. Materials and Methods: Two hundred children were recruited for this study during the period of five years from January, 2014 to December, 2018 at Otolaryngology department of Khwaja Yunus Ali Medical College and Hospital (KYAMCH). Subjects between the age of 5 and 25 years listed for tonsillectomy were included. Subjects were recommended not to have aspirin within the 2 weeks before surgery. Results: The mean duration of operation was found 10.6±0.4 minutes in group A and 17.0±0.7 minutes in group B. The difference was statistically significant (p<0.05) between two groups. At 1st day, 11(11.0%) patients had throat pain in group A and 23(23.0%) in group B. At 2nd day, 14(14.0%) patients had throat pain in group A and 25(25.0%) in group B. Which were statistically significant (p<0.05) between two groups. Conclusion: The monopolar diathermy tonsillectomy appears to cause less bleeding, postoperative pain and less time consuming in compare with the dissection tonsillectomy although patients experience slightly more pain than dissection Method.

Background: Transcatheter pulmonary valve insertion has recently emerged as an alternative to surgery. To extend the indications to patients with large right ventricular outflow tract (RVOT), we previously developed an intravascular device that reduces the diameter of the main pulmonary artery (MPA) allowing the insertion of available valved stents. We report its use in a model of animals with enlarged RVOT and pulmonary valve incompetence (PVI). Methods and Results: 33 sheep were included. They first underwent surgical MPA enlargement. We then intended to implant percutaneously a reducer followed by the insertion of a valve. Three animals died during interstage. The remaining were sacrificed acutely (group 1, n=6), after a mean follow-up of 1 (group 2, n=12) and 2 months (group 3, n=12). Animals from chronic groups were equally divided into 2 subgroups according to the difference between diameters of the device inserted and MPA (A: < 5-mm, B: ≥ 5-mm). Reducers were inserted successfully (n=30). One embolized after its insertion (Group 3A). A valved stent could be implanted in all animals but one which experienced a balloon ruptured during its inflation leading to incomplete expansion and death of the animal. Six animals had pulmonary regurgitation after valve insertion. Five of them (Group A, n=5; Group B, n=1) had downsizing of the reducer. Conclusion: Pulmonary valve insertion is possible through a transcatheter technique using a PA reducer. Oversizing of this device reduces the risk of embolisation and paraprosthetic leak.
