Serological survey for SARS-CoV-2 antibodies among tribal communities of Odisha post-second wave.

Background & objectives: Serial national level serosurveys in India have provided valuable information regarding the spread of COVID-19 pandemic in the general population, but the impact of the ongoing pandemic on the tribal population in India is not well understood. In this study, we evaluated the seroprevalence of COVID-19 antibodies in the tribal population of Odisha post-second wave (September 2021). Methods: A population-based, age-stratified, cross-sectional study design was adopted for the survey, carried out in seven tribal districts of Odisha from 30th August to 16th September 2021. A multistage random sampling method was used where serum samples were tested for antibodies against the SARS-CoV-2 nucleocapsid (N) protein in each district, and a weighted seroprevalence with 95 per cent confidence interval (CI) was estimated for each district. Results: A total of 2855 study participants were included from the seven tribal districts of Odisha in the final analysis. The overall weighted seroprevalence was 72.8 per cent (95% CI: 70.1-75.3). Serological prevalence was the highest among 18-44 yr (74.4%, 95% CI: 71.3-77.3) and from Sambalpur district [75.90% (66.90-83.10)]. Among participants, 41.93 per cent had received at least one dose of any COVID-19 vaccine. Kandhamal district had the highest number of fully immunized participants (24.78%), and in Sundergarh district, most of the study participants (58.1%) were unimmunized. Interpretation & conclusions: This study found high seroprevalence against SARS-CoV-2 in the tribal population of Odisha. The vaccination coverage is at par with the general population, and efforts to address some knowledge gaps may be needed to improve the coverage in the future.

Emotional well-being of dentists and the effect of lockdown during the COVID-19 pandemic: A nationwide study.

BACKGROUND: Lockdown in India might have adverse effects on the emotional health of the dental professionals; hence, the aim of the present study was to determine the impact of various factors on emotional well-being of dental professionals due to the effect of lockdown during COVID-19. MATERIALS AND METHODS: It was a cross-sectional, descriptive, questionnaire study conducted on dentists in India during April 2020. Sampling technique was convenient sampling, and sampling frame was all the dental professionals in India. The questionnaire was prepared online using Google Forms, and the link was generated which was shared among as many dentists accessible as possible, with the help of message, mails, and WhatsApp. The questionnaire consists of questions on Demographic details, practice, and emotional well-being. A total of 1844 dental professionals in 14 states in India responded. The statistical analysis was done using SPSS version no. 20. IBM SPSS version 20.0 (IBM; Armonk, New York USA) Descriptive statistics and multinomial regression test was applied. RESULTS: Majority of study participants (1096 [59.4%]) belonged to age group of 26-35 years. Emotional well-being score of 1206 (65.4%) dental professionals in the times of COVID-19 outbreak was poor with score between 26 and 78. It was assessed that males have significantly (P = 0.00**) (P < 0.001**) (**highly significant) poorer emotional well-being 0.085 (0.829-1.429) compared to females. Married dental professionals - 0.023 (0.011-1.221) had significantly better (P = 0.05*) emotional well-being than others. CONCLUSION: Emotional well-being score of majority of dental professionals in the times of COVID-19 outbreak was poor. Gender, marital status, socioeconomic status, years of experience, practicing in clinic, and average number of patients seen per month before lockdown have significant impact on emotional wellbeing of dental professionals.

Juvenile Nasopharyngeal Angiofibroma: A Case Report.

Juvenile nasopharyngeal angiofibroma is tumour almost exclusively seen in adolescent males, constituting less than 1% of all neoplasms in head and neck. They are benign and locally spreading and are highly vascular in nature and thus prove to be a surgical challenge because of its complex anatomical location. Here, we present a case report of a 18-year-old male presenting with a mass in his left nasal cavity, with recurrent epistaxis and nasal obstruction. Computed tomography imaging revealed a non-encapsulated lobulated heterogeneous mass lesion in the naso-pharynx and left posterior choana of the nasal cavity, extending to pterygopalatine and infratemporal fossa, masseter space of left side. The approach to its surgical management was a combined multi-disciplinary effort of otorhinolaryngology surgeons and maxillofacial surgeons.

Efficacy of 0.25% Lemongrass Oil Mouthwash: A Three Arm Prospective Parallel Clinical Study.

BACKGROUND: Chlorhexidine mouthwash has earned eponym of gold standard to treat and/or prevent periodontal diseases. However, the present study was carried out to explore an alternative herbal mouthwash. AIM: To compare the anti-plaque and anti-gingivitis efficacy of a 0.25% lemongrass oil mouthwash to that of 0.2% chlorhexidine mouthwash. MATERIALS AND METHODS: A double-blinded parallel designed clinical trial with 60 subjects was taken for the study. Baseline plaque index (PI) & gingival index (GI) score was recorded. Oral prophylaxis was done and the plaque score was set at zero. Then, subjects were randomly allocated into 3 groups (N=20 in each): 0.25% lemongrass oil mouthwash, 0.2% chlorhexidine mouthwash and oral prophylaxis only. Subjects were asked to swish with respective mouthwash twice daily for 21 days. Subjects were again re-evaluated on 14(th) and 21(st) day for GI and PI. Comparison of the mean difference among the variables was performed by parametric tests. RESULTS: Lemongrass oil mouthwash group showed highest reduction in GI & PI at both 14(th) and 21(st) day, which was statistically significant (p≤0.05). CONCLUSION: Lemongrass oil mouthwash can also be used as a good herbal alternative to chlorhexidine mouthwash, so further studies are needed.

Perception of Dental Professionals towards Biostatistics.

Biostatistics is becoming an integral part of dental sciences. Awareness regarding the subject is not thoroughly assessed in the field of dentistry. So the study was conducted to assess dental professionals' knowledge, attitude, and perception toward biostatistics at an academic dental institution. An anonymous cross-sectional questionnaire survey was conducted among all the faculty and postgraduate students of two dental colleges in Moradabad, Uttar Pradesh. The responses were assessed on 5-point likert scale. The survey response rate was 73.71%. Two-thirds of respondents believed biostatistics to be a difficult subject and at the same time half of them did not consider it to be more difficult than other subjects in dentistry. Females were less competent than males in applying biostatistical skills which was found to be statistically significant. Results suggested that dentists with research or academics as an adjunct to their clinical practice had better command over the subject. The current study shows that there is lack of command over the subject of biostatistics among dental professionals although they were aware of its importance in dentistry. There is a need of changing the training pattern of biostatistics for dental professionals which would make them confident enough to apply biostatistics in their clinical practice.

Social capital and oral health.

Social determinants have always been an important element of the oral health. It has been seen that social aspects like the organizations and relations influence the health of population. A new domain named social capital has come up into limelight which refers to "features of social organization, such as trust, norms and networks that can improve the efficacy of society by facilitating coordinated actions". The bonds between individuals, both in intimate relationships and in voluntary associations have been claimed to have health promoting effects. Oral health can never be segregated from general health as they are bidirectional in their relationship. Therefore determinants of general health and its promotion are interlinked with that of oral health. So, this review tries to figure out the effects of social capital on various aspects of oral health.
