Maxillary dental arch width changes by extraction and non-extraction orthodontic treatment among angle’s class I malocclusion patients

This study examined the pretreatment and post treatment dental arch width changes between the extraction and non-extraction cases in Angle’s class I patients. Sixty pre-treatment and post-treatment dental casts from 30 extractions and 30 non-extractions participants were selected for the study. The inter-canine and inter-molar maxillary arch width were measured by Vernier gauge caliper. An unpaired t-test was performed to evaluate the arch width changes between extraction and non-extraction groups. The results showed that inter-molar and inter-canine maxillary arch widths in the non-extraction group were slightly higher than those in the extraction group in both pre- and post-treatment, but the differences were not statistically significant. In conclusion, the extraction and non-extraction techniques used in orthodontic treatment did not change the inter-caning and inter-molar arch widths

This article has no abstract. The first 100 words appear below: A 14-year-old male came to the outpatient Department with the complaints of proclination of the tooth and inability to close his lips. The patient was psychologically depressed for his facial appearance. Extraoral clinical examination showed a mesocephalic symmetrical face with convex facial profile as well as his lower lip was trapped The  nasolabial angle was acute. His mandibular movement was normal and there was no temporomandibular joint dysfunction

COVID-19 vaccine barriers and perception among rural adults: a qualitative study in Bangladesh

Objective The COVID-19 pandemic continues to pose challenges for global public healthcare, even with the authorisation of several vaccines worldwide. To better understand rural communities’ knowledge, attitudes, perceptions and barriers towards these vaccines, we conducted a qualitative cross-sectional study with adults in rural Bangladesh.Setting This cross-sectional study was conducted in the rural areas of Sylhet and Natore in Bangladesh from August 2021 to February 2022.Participants Our study involved 15 in-depth interviews with rural adults and 2 key informant interviews with health workers.Results We analysed data thematically, resulting in four main themes: (1) knowledge and perception aspects, (2) myths and misconceptions, (3) practice and attitude and (4) barriers and challenges of COVID-19 vaccines.Conclusions The findings indicate that rural populations lack sufficient knowledge about COVID-19 vaccines but have a more favourable attitude towards them. Misconceptions, beliefs and personal experiences were found to be the main reasons for vaccine avoidance. To address these challenges and dispel the spread of misinformation, health education programmes play a pivotal role in improving vaccine management. Policy-makers should initiate these programmes without delay to create a well-informed and enlightened community, given that the COVID-19 is still spreading
