Clinical Efficacy of Concentrated Growth Factors for the Management of Marginal Tissue Recession: A Systematic Review and Meta-Analysis.

INTRODUCTION: To systematically review existing scientific literature to determine, compare, and evaluate whether concentrated growth factors (CGF) or connective tissue grafts (CTG) is a better treatment alternative for patients with marginal tissue recession (MTR). METHODS: Electronic databases like PubMed, Embase, Scopus, and Google Scholar were screened from the last 20 years reporting treatment of MTR using CGF or CTG and other techniques. Periodontal parameters like probing depth, clinical attachment level, recession depth, recession width, keratinized tissue width, root coverage, increase in gingival thickness and plaque index, and gingival index were compared. Standardized mean difference was used as a summary statistic measure with a random effect model and P value <0.05 as statistically significant. RESULTS: Six studies fulfilled eligibility criteria and were included in qualitative synthesis, of which only 4 studies were suitable for meta-analysis. The pooled estimate through standardized mean difference signifies that CGF was superior to CTG in the reduction of probing depth, gingival index, and plaque index and gain in clinical attachment level while CTG was superior in reducing the recession depth and recession width. Both the procedures had an overall equal effect on keratinized tissue width and root coverage, but these differences were statistically insignificant (P>0.05). Publication bias through the funnel plot showed symmetric distribution without systematic heterogeneity. CONCLUSION: The present study suggests that treatment of MTR with CTG or CGF resulted in clinically favorable outcomes, but no statistically significant differences was observed between these 2 procedures regarding the outcome.

Cytotoxicity of TiO2 nanoparticles towards freshwater sediment microorganisms at low exposure concentrations.

There is a persistent need to assess the effects of TiO2 nanoparticles on the aquatic ecosystem owing to their increasing usage in consumer products and risk of environmental release. The current study is focused on TiO2 nanoparticle-induced acute toxicity at sub-ppm level (≤1ppm) on the three different freshwater sediment bacterial isolates and their consortium under two different irradiation (visible light and dark) conditions. The consortium of the bacterial isolates was found to be less affected by the exposure to the nanoparticles compared to the individual cells. The oxidative stress contributed considerably towards the cytotoxicity under both light and dark conditions. A statistically significant increase in membrane permeability was noted under the dark conditions as compared to the light conditions. The optical and fluorescence microscopic images showed aggregation and chain formation of the bacterial cells, when exposed to the nanoparticles. The electron microscopic (SEM, TEM) observations suggested considerable damage of cells and bio-uptake of nanoparticles. The exopolysaccrides (EPS) production and biofilm formation were noted to increase in the presence of the nanoparticles, and expression of the key genes involved in biofilm formation was studied by RT-PCR.

Narrative review on artificially intelligent olfaction in halitosis.

Halitosis, commonly known as oral malodor, is a multifactorial health concern that significantly impacts the psychological and social well-being of individuals. It is the third most frequent reason for individuals to seek dental treatment, after dental caries and periodontal diseases. For an in-depth exploration of the topic of halitosis, an extensive literature review was conducted. The review focused on articles published in peer-reviewed journals and only those written in the English language were considered. The search for relevant literature began by employing subject headings such as 'halitosis, oral malodor, volatile sulfur compounds, artificial intelligence, and olfaction' in databases such as PubMed/Medline, Scopus, Google Scholar, Web of Science, and EMBASE. Additionally, a thorough hand search of references was conducted to ensure the comprehensiveness of the review. After amalgamating the search outcomes, a comprehensive analysis revealed the existence of precisely 134 full-text articles that bore relevance to the study. Abstracts and editorial letters were excluded from this study, and almost 50% of the full-text articles were deemed immaterial to dental practice. Out of the remaining articles, precisely 54 full-text articles were employed in this review. As primary healthcare providers, dentists are responsible for diagnosing and treating oral issues that may contribute to the development of halitosis. To effectively manage this condition, dentists must educate their patients about the underlying causes of halitosis, as well as proper oral hygiene practices such as tongue cleaning, flossing, and selecting appropriate mouthwash and toothpaste. This narrative review summarises all possible AI olfaction in halitosis.

Effectiveness of herbal oral care products in reducing dental plaque and gingivitis: an overview of systematic reviews.

Introduction: Numerous clinical trials and systematic reviews have investigated the effectiveness of both herbal and conventional oral care approaches to reducing plaque and gingivitis. However, their findings vary and are inconsistent. Thus, the objective of this umbrella review is to compile data from systematic reviews and provide an overview of the effects of herbal oral care products on tooth plaque and gingivitis. Methods: A comprehensive search of the literature was performed in 6 databases for systematic reviews with or without meta-analyses, published up to 30 May 2023, without any language restrictions. Only clinical trials comparing herbal oral care products (in the form of mouthrinse or toothpaste) against standard oral care products or placebo were considered. Results: Some herbal oral care products, particularly in the form of mouthrinses, have a similar level of positive effect on plaque and gingivitis reduction and, thus, can be used as an adjunct to traditional dentifrices. However, the shorter duration of trials (<4 weeks) and reported publication bias in the clinical trials mean that these findings must be interpreted with caution. Conclusion: To accurately determine the impact of various herbal extracts on periodontal health, well-designed, long-term, and controlled trials that adhere to standardized protocols must be carried out.

Introduction: On a étudié l'efficacité d'approches de soins buccodentaires classiques et à base de plantes pour lutter contre la plaque dentaire et la gingivite dans le cadre de nombreux essais cliniques et revues systématiques. Toutefois, leurs conclusions ont été variables et incohérentes. Cette revue générale vise donc à compiler des données issues de revues systématiques et de présenter un aperçu des effets des produits de soins buccodentaires à base de plantes sur la plaque dentaire et la gingivite. Méthodes: On a procédé à une recherche documentaire exhaustive dans 6 bases de données pour effectuer des revues systématiques, avec ou sans méta-analyses, sans aucune restriction relative à la langue de l'étude, publiées avant le 30 mai 2023. Seuls des essais cliniques comparant des produits de soins buccodentaires à base de plantes (sous forme de rincebouche ou de dentifrice) à des produits de soins buccodentaires classiques ou à des placebos ont été envisagés. Résultats: Quelques produits de soins buccodentaires à base de plantes, en particulier les rince-bouches de ce type, ont des effets positifs comparables en matière de réduction de la plaque et de la gingivite et peuvent donc être utilisés en complément des dentifrices ordinaires. Toutefois, ces résultats doivent être interprétés avec prudence du fait de la durée relativement courte des essais (moins de 4 semaines) et du biais de publication signalé dans les essais cliniques. Conclusion: Pour déterminer avec précision les effets de divers extraits de plantes sur la santé parodontale, il est nécessaire d'avoir recours à des essais bien conçus, à long terme et contrôlés, qui respectent des protocoles normalisés.

Root canal therapy used in conjunction with follow-ups for the nonsurgical handling of an enormous periapical lesion of endodontic origin: Clinical case record.

Key Clinical Message: The main objective of root canal therapy is to locate all the canals, cleaning, and shaping, and obturation to obtain fluid tight seal and to heal the periapical lesion if present. Abstract: The proper cleaning, shaping, and disinfection of the pulp chambers, as well as the filling of the canals, are critical to the efficacy of treatment with root canals. The success of an endodontically treated tooth is dependent on the accuracy of the diagnosis, disinfection, cleaning and shaping, obturation, and finally, the prosthetic rehabilitation management. Root canal therapy should provide a hermatic as well as fluid impenetrable seal which prevents the progression of periapical infection. There are two ways to treat such lesions: surgical and nonsurgical methods. If the root canal is cleaned, shaped, and sealed properly and adequately without the use of a surgical procedure, these lesions will recover during nonsurgical root canal therapy. This case series focuses primarily on the nonsurgical treatment of an enormous periapical lesion and provides evidence that these lesions respond well without surgery.

Applications of robot-assisted UV disinfection in dentistry.

Maintaining a microbial-free environment in healthcare facilities is more widely recognized as an essential component of therapies to minimize transmission of viruses associated with healthcare sector. The global spread of COVID-19 and recent outbreaks have presented humanity with previously unheard-of challenges. The development of autonomous disinfection robots seems to be necessary given the urgent need for constant sterilization in the face of a labor shortage. Due to their automated and perceived cost advantages by eliminating cleaning staff, these robots are being advertised more and more as an easy solution to immediately disinfect rooms and operating areas. The use of these services lowers the danger of infection, and expense of traditional cleaning and, most significantly, builds trust and security in medical facilities. Currently, routine (manual) cleaning is not replaced by disinfection robots; rather, they may support it. Additional hospital and device design alterations are necessary to address the overshadowing (visibility) issue allowing Ultraviolet disinfectant (UV-D) robots move freely in the medical environment. More technical developments and clinical studies in a variety of hospitals are needed to overcome the current challenges and find ways to integrate this unique technology into hospitals now and in the future. Thus, we present a review that includes detailing all elements required for it to function, as well as both its advantages and disadvantages. To the best of our knowledge, very limited studies have collected an in- depth data on the sterilization effect using a disinfection robot in the field of dentistry. We believe that this data will work as a foundation in more advanced uses at diverse sites that require disinfection and will highlight unsolved challenges and potential research avenues for UV robot operational concerns in dental hospitals. The goal of this work is to offer a comprehensive manual for UV-D robots covering pertinent information on traditional Ultraviolet germicidal irradiation (UVGI) system along with advancements in UV-D robots and thereby focusing on in-depth application in medical and dental facilities.

A Brief Review on Engaging and Interactive Learning for Children: Exploring the Potential of Metaverse-Based Oral Health Promotion.

The importance of oral health for overall health makes it critical to establish proper oral hygiene practices in children early on. The traditional approaches to teaching children about dental health may not be successful since they may not be able to keep their interest. Metaverse technology offers a promising alternative, allowing for the design of engaging and immersive worlds that can effectively educate children about oral health. Despite the growing interest in the use of metaverse technology in healthcare, there is a lack of comprehensive reviews on its potential for oral health promotion in children. This review aims to fill this gap by providing an overview of the current state of metaverse-based oral health promotion for children, discussing its benefits and challenges, and highlighting its potential for improving children's oral health. By conducting this review, the authors hope to provide new information on the potential of metaverse-based oral health promotion for children and to contribute to the ongoing discussion on the use of metaverse technology in healthcare. This review may also provide valuable insights for dental organizations and practitioners interested in using metaverse technology to promote oral health and healthy living among children.

Oral health status among the transgender population of India: A systematic review and meta-analysis.

BACKGROUND: The invisibility of the transgender population within official records, combined with other socio-economic factors, impacts oral health status among transgender people. Hence, our systematic review and meta-analysis aim to generate a pooled estimate of the oral health status of the transgender community in India. MATERIAL AND METHODS: A systematic search was performed across four databases. The studies included a quantitative research design conducted in India and involved self-identified transgender individuals. The pooled prevalence was determined at a 95% confidence interval (CI). Q-statistics and the I2 test were utilized to evaluate the source of heterogeneity. Leave-one-out analysis and Baujat plots were used to detect outliers within the studies. A Doi plot and LFK index were employed to assess the publication bias. RESULTS: A total of 12 studies comprising 1566 transgender participants were included. The pooled prevalence of toothbrush use among transgenders in India was found at 83% (95% CI: 0.73-0.91), smoking = 12% (CI: 0.03-0.26), smokeless tobacco = 53% (CI = 0.38-0.68), dental caries = 78% (CI: 67%-88%), calculus = 65% (CI: 0.4-0.86), and bleeding 18% (CI:0.08-0.32). CONCLUSION: Oral health disparities among Indian transgender individuals are evident in the low toothbrush usage, an elevated prevalence of tobacco use, and dental disorders such as calculus, cavities, and bleeding. Tailored dental health programs that include inclusive healthcare services and awareness are essential. PROSPERO REGISTRATION: CRD42023468872.

Artificial Intelligence in Dental Caries Diagnosis and Detection: An Umbrella Review.

BACKGROUND AND AIM: Dental caries is largely preventable, yet an important global health issue. Numerous systematic reviews have summarized the efficacy of artificial intelligence (AI) models for the diagnosis and detection of dental caries. Therefore, this umbrella review aimed to synthesize the results of systematic reviews on the application and effectiveness of AI models in diagnosing and detecting dental caries. METHODS: MEDLINE/PubMed, IEEE Explore, Embase, and Cochrane Database of Systematic Reviews were searched to retrieve studies. Two authors independently screened the articles based on eligibility criteria and then, appraised the included articles. The findings are summarized in tabulation form and discussed using the narrative method. RESULT: A total of 1249 entries were identified out of which 7 were finally included. The most often employed AI algorithms were the multilayer perceptron, support vector machine (SVM), and neural networks. The algorithms were built to perform the segmentation, classification, caries detection, diagnosis, and caries prediction from several sources, including periapical radiographs, panoramic radiographs, smartphone images, bitewing radiographs, near-infrared light transillumination images, and so forth. Convoluted neural networks (CNN) demonstrated high sensitivity, specificity, and area under the curve in the caries detection, segmentation, and classification tests. Notably, AI in conjunction with periapical and panoramic radiography images yielded better accuracy in detecting and diagnosing dental caries. CONCLUSION: AI models, especially convolutional neural network (CNN)-based models, have an enormous amount of potential for accurate, objective dental caries diagnosis and detection. However, ethical considerations and cautious adoption remain critical to its successful integration into routine practice.

Effect of Repeated Moist Heat Sterilization on Titanium Implant-Abutment Interface-An In Vitro Study.

OBJECTIVES: Sterilization eliminates microbial viability by decreasing the biological load, but likewise have the ability to deteriorate the mechanical properties of an implant material. This study intended to evaluate the effect of repeated moist heat sterilization on implant-abutment interface using two different implant systems. MATERIALS AND METHODS: Forty screw-retained titanium implant-abutment combinations (fixture 3.5 ×10 mm, abutment 2 mm diameter), twenty each from Genesis (Aktiv Implant Systems, United States) and Bredent (SKY, Germany), were divided into four different groups (n = 10) and placed in a computer-aided diagnostic model. The abutments from each group were exposed to first and second autoclave cycle (121°C for 30 minutes), connected back to the fixture and analyzed under scanning electron microscope for marginal gap and surface roughness. RESULTS: Genesis group showed higher marginal gaps on both sides (buccal/mesial [2.8 ± 0.47]; lingual/distal [2.8 ± 0.33]), while Bredent implant-abutment system (IAS) did not show any changes in marginal gaps after autoclaving. Differences within and between the group were found to be statistically significant. Surface roughness for Genesis (243.7 ± 70.30) and Bredent groups (528.9 ± 213.19) was highest at second autoclave, with Bredent implant-abutment showing higher values for surface roughness than Genesis IAS. CONCLUSION: Marginal vertical gap increased with autoclaving for Genesis IAS, while Bredent implant abutments were more stable. Surface roughness increases with autoclaving for both Genesis and Bredent group of IAS.

Effectiveness of fluoride mouthrinse in prevention of demineralization during fixed orthodontic treatment: A systematic review and meta-analysis.

Enamel demineralization is a very common occurrence around bonded brackets in an orthodontic practice. Fluoride (FLR) applications have been used to prevent decalcification and further progression of white spot lesions. The purpose of this systematic review and meta-analysis was to systematically appraise available literature on the effectiveness of fluoride mouthrinse in the prevention of demineralization around fixed orthodontic appliances. A search was conducted for randomized controlled clinical trials among four electronic databases (MEDLINE, Google Scholar, PubMed, and Cochrane Review) through MeSH terms and keywords. Studies were excluded if random allocation was not conducted, or if they were animal or in vitro studies. About 146 articles were screened and 5 studies were selected for the present review. Only two studies were selected for MA due to variations in the measurement of outcomes among studies. This review concluded that rinsing with FLR in the course of the fixed orthodontic treatment lessens demineralization around the bracket. Using FLR mouthrinse to inhibit the formation of white spot lesions or dental caries in patients with multiple cavities or restoration can be considered in clinical practice.

Correlation between rheumatoid arthritis and chronic periodontitis: a systematic review and meta-analysis.

INTRODUCTION: The aim of this article is to summarize, compare, and assess possible association in individuals with or without rheumatoid arthritis (RA) for periodontitis. EVIDENCE ACQUISITION: Three study repositories were searched for quantitative studies examining the relationship between periodontal disease and rheumatoid arthritis between 2000 and December 2022. Quality was evaluated using the Newcastle Ottawa Scale (NOS). The standardized mean difference (SMD), with a random effect model and a P value of 0.05 as the significance level, was utilized as a summary statistic measure. EVIDENCE SYNTHESIS: Fourteen papers were included in the descriptive synthesis. Thirteen were qualified for meta-analysis. Our findings suggest a link between the two conditions in terms of clinical attachment levels (CAL), tooth loss, Plaque Index, and probing depth. The estimated SMD for CAL was found to be 0.68 (95% CI: 0.15-1.21) (P<0.01). For tooth loss, the forest plot analysis revealed an SMD of 1.62 (95% CI: 0.48-2.76) (P=0.005). Similarly, for pocket depth, the SMD was 0.53; CI: 0.07-0.99 (P>0.05). The pooled estimates for plaque index were 0.29; CI: 0.03-0.61 (P>0.05). The funnel plot showed a symmetric distribution with the absence of systematic heterogeneity. CONCLUSIONS: Although our data suggest a link between periodontal disease and rheumatoid arthritis, larger population-based investigations are needed to validate this connection. Case-control studies must pave the way to more rigorous investigations with well-defined populations and clinical outcomes as primary outcome measures.

Oral health status of prisoners in India: A systematic review and meta-analysis.

AIMS: Given the high prevalence of oral health problems among prisoners, the goal of this systematic review is to provide a better knowledge of the scope of this problem. METHODS: Electronic searches of PubMed/MEDLINE, Embase, Scopus, and Google Scholar were performed. Studies that investigated inmates aged 18 or older with oral health problems were eligible. Variables reported in four or less studies were described narratively. Conversely, for variables reported in more than four studies, a meta-analysis was performed using random effect model. Furthermore, meta-regression and sensitivity analysis is also performed to evaluate moderator effect on outcome. Doi and LFT index is applied to assess publication bias. RESULTS: Out of 494 results, 12 studies were included. The pooled prevalence of caries among prisoners is 78.42% (59.48%-92.58%). On meta-regression, the prevalence of caries appears to be lower in studies with a higher male percentage; however, non-significant (p = .079) due to small sample size. Community periodontal index (CPI) scores revealed periodontal disease, with scores of 3 and 4. Moreover, a significant need for oral hygiene instruction, prosthesis, extraction, and tooth ache, periodontal disease, oral mucosal lesions, leucoplakia, attrition, abrasion, bruxism, and smoking behaviors were also reported. CONCLUSION: Poor oral health status in the incarcerated population highlights the urgent need for comprehensive oral health intervention in prisons.

The differential stress response of adapted chromite mine isolates Bacillus subtilis and Escherichia coli and its impact on bioremediation potential.

In the current study, indigenous bacterial isolates Bacillus subtilis VITSUKMW1 and Escherichia coli VITSUKMW3 from a chromite mine were adapted to 100 mg L(-1) of Cr(VI). The phase contrast and scanning electron microscopic images showed increase in the length of adapted E. coli cells and chain formation in case of adapted B. subtilis. The presence of chromium on the surface of the bacteria was confirmed by energy dispersive X-ray spectroscopy (EDX), which was also supported by the conspicuous Cr-O peaks in FTIR spectra. The transmission electron microscopic (TEM) images of adapted E. coli and B. subtilis showed the presence of intact cells with Cr accumulated inside the bacteria. The TEM-EDX confirmed the internalization of Cr(VI) in the adapted cells. The specific growth rate and Cr(VI) reduction capacity was significantly higher in adapted B. subtilis compared to that of adapted E. coli. To study the possible role of Cr(VI) toxicity affecting the Cr(VI) reduction capacity, the definite assays for the released reactive oxygen species (ROS) and ROS scavenging enzymes (SOD and GSH) were carried out. The decreased ROS production as well as SOD and GSH release observed in adapted B. subtilis compared to the adapted E. coli corroborated well with its higher specific growth rate and increased Cr(VI) reduction capacity.

India's Union Budget 2023-Healthcare allocation leaves much to be desired.

Healthcare is an imperative sector for India, considering the huge population in the country and the sub-par health facilities available to a majority of the country's people. In this scenario, and given the havoc wreaked by the COVID-19 pandemic, owing to India's lack of optimal healthcare infrastructure, a large part of the healthcare industry expected that India's Union Budget 2023 would provide significant outlays for the sector. However, with the budgetary outlay for healthcare coming in at the 10th position from the top, this hope was severely dashed, leading to questions about the country's interest in providing healthcare facilities to its people. This article discusses the various facets of the Union Budget, and the lack of focus on healthcare, while also delineating the reasons why budgetary focus on healthcare is imperative for a developing country like India. It has also brought forth potential solutions, such as a public-private partnership in healthcare, which could ensure increased access to healthcare, improved quality of healthcare, reduced costs, and enhanced innovation and research.

The role of Weizmannia (Bacillus) coagulans LMG S-31876 in treating IBS-diarrhea.

Introduction: Irritable bowel syndrome (IBS) is a common gastrointestinal condition. Some studies have shown the efficacy of probiotics in the treatment of irritable bowel syndrome (IBS). Weizmannia (Bacillus) coagulans LMG S-31876 has been marketed as a dietary ingredient, but to date, its efficacy in diarrhea-predominant irritable bowel syndrome (IBS) condition has not been clinically elucidated. Thus, a double-blind placebo-controlled multi-centered trial was planned to evaluate the safety and efficacy of Weizmannia (Bacillus) coagulans LMG S-31876 in diarrhea-predominant IBS patients. Experimental design: Study participants (n = 50) diagnosed with IBS prominent symptoms that include abdominal pain and other GI-related symptoms were treated with ProBC Plus (2 billion CFU) along with a placebo capsule once daily for approximately 8 weeks. Study participants were evaluated for the treatment success determined by the differences in stool consistency and frequency per day between the intervention and placebo groups over the study period. Results: The vital signs and the biochemistry parameters were under the normal range; the other parameters showed a significant result as compared to the placebo during the study period. Conclusion: This study depicts a significant decline in the clinical symptoms such as abdominal pain, bloating, diarrhea, and frequency of the stool as compared to the placebo. All the parameters such as hematology, lipid profile, and vital signs were in the normal range during the supplementation of ProBC Plus for a period of 8 weeks. Furthermore, the study verified that Weizmannia (Bacillus) coagulans LMG S-31876 and its probiotic product ProBC Plus at a dose of 2 billion/CFU/day has a prominent action in the relief from the clinical symptoms of IBS-D. Therefore, the product is intended safe to utilize for IBS-related symptoms.Clinical trial registration: The clinical study has been registered with CTRI/2023/01/048644 with https://ctri.nic.in/Clinicaltrials/pmaindet2.php?trialid=77708&EncHid=24313.96864&userName=CTRI/2023/01/048644 [CTRI/2023/01/048644].

Role of various pharmacologic agents in alveolar bone regeneration: A review.

Alveolar bone and gingiva are components of the periodontium that house the tooth. It constantly adapts itself to the masticatory forces and position of the tooth. However, localized diseases like chronic periodontitis and certain systemic diseases destroy periodontal tissues, which include the alveolar bone. Various pharmacological agents are being explored for their pleiotropic properties to combat the destruction of alveolar bone. This review focuses on the role of pharmacological agents in alveolar bone regeneration.

Comparative evaluation of three different regression-equation-based mixed dentition analysis of children for prediction of the mesiodistal width of permanent canine and premolars.

BACKGROUND: Dental malocclusion is common all over the world, and it is caused by a difference in arch length and tooth size. This necessitates mixed dentition analysis for early intervention treatment planning such as eruption guiding, serial extraction, space maintainer, space regainer, and jaw extension. The aim of the study is to comparatively evaluate three different regression equation based mixed dentition analysis of children for prediction of the mesiodistal width of permanent canine and premolars in population of Vidarbha region. METHODS: This study comprised of 300 patients aged 13 to 16 years old. The impressions of patients were poured, and the mesiodistal width of their teeth was measured and documented. Three independent analyses were performed using the Ling and Wong method (L&W), the Bernabe and Flores-Mir method (B&F), and the Tanaka and Johnston method (T&J), and the results were compared to the sum of permanent canine and premolar teeth (SPCP). ANOVA with post hoc analysis was used to compare the predicted mesiodistal diameter (MDD) by analysis to the SPCP observed on cast. RESULTS: The mesiodistal width of SPCP of maxilla and mandibular teeth had statistically significant difference (P<0.001) with the predicted width by Ling and Wong method, Bernabe and Flores method and Tanaka and Johnston method for patients of Vidarbha region. CONCLUSIONS: The study concluded that all the three analysis overestimated the mesiodistal width of the sum of permanent canine and premolar in the patients. Tananka and Johnston analysis method was better in predicting the SPCP of the children of Vidarbha region.

COVID-19 Vaccine Hesitancy among the General Population: A Cross-Sectional Study.

Hesitancy about receiving vaccines has been deemed a global danger to public health by WHO. The sociocultural backgrounds of the people have an impact on vaccine acceptance. The purpose of this study was to examine the effect of sociodemographic factors on COVID-19 vaccination hesitancy as well as to identify the factors that contributed to COVID-19 vaccine hesitancy. METHODS: A cross-sectional study was carried out to determine the primary variables causing COVID-19 vaccination hesitancy among residents of Pune. The general population was sampled through simple random sampling. The minimum sample size was determined to be 1246. The questionnaire inquired about the individuals' sociodemographic information, vaccination status, and reasons for vaccine hesitancy. RESULTS: In total, there were 5381 subjects, 1669 of whom were unvaccinated and 3712 of whom were partially vaccinated. Fear of adverse effects (51.71%), fear of losing a few days of work (43.02%), and inability to secure a vaccine slot online (33.01%) were the most frequently cited reasons. An older population (>60 years, p = 0.004), males (p = 0.032), those who were literate (p = 0.011), those of lower middle socioeconomic status (p = 0.001), and smokers were significantly associated with fear and mistrust of the COVID-19 vaccine, while mistrust of the vaccine was greatest among individuals from the upper and lower middle classes (p = 0.001). CONCLUSION: Vaccine hesitancy due to concerns about the side effects and long-term complications was prevalent among the elderly, males, those from the lower middle class, and smokers. This study emphasizes the importance of communicating effectively about the vaccine's efficacy, its distribution, and vaccination sites.
