Effectiveness of Honey and Aloe Vera on the Post Extraction Healing Among Young Adults: A Randomized Clinical Trial
INTRODUCTION: "Dry socket" was first described by Crawford in literature in 1896. When people are recognizing that current medicine is not the soul cure for diseases, we look back to the past for potential remedies with the least possible side-effectiveness. So the objective of this study was to evaluate the effectiveness of honey and aloevera on healing of post extraction wounds. MATERIAL AND METHODS: Honey and aloe-vera were prepared by mixing with sterilized cotton. The socket involved was separated by dry autoclaved cotton rolls from the rest of the oral cavity, then honey/aloe-vera was inserted into the respective groups. All patients were advised to avoid solid and liquid diets for 30 minutes after the treatment. Dressings were changed on 3rd day and on 7th day and sockets were evaluated. RESULTS: When the intra-group comparison of honey (p-value=0.003) and aloe-vera (p-value=0.000) was done, both were found to be statistically significant in the healing of dry socket. When the inter-group comparison was done between honey and aloe-vera, Aloe-vera had high healing capacity and was found to be highly statistically significant (p-value=0.001). DISCUSSION: When the intra-group comparison of honey and aloe-vera was done, both were found to be statistically significant in the reduction of dry socket. When the inter-group comparison was done between honey and aloe-vera, Aloe-vera had high healing capacity and was found to be highly statistically significant (p-value=0.00). CONCLUSION: From the analysis, it can be inferred that aloe vera and honey are healthy, natural and user-friendly substitute adjuncts that might be feasible to promote healing of extraction sockets
Effect of Summer Temperature on the Work Efficiency of Dentists
INTRODUCTION AND AIM: Environment is closely related to human health. While the effects of temperature on comfort are broadly recognized, the effects on worker productivity have received much less attention. Thus this research was planned to investigate the effects of heat stress on job satisfaction, job performance, occupational stress among dentists.
MATERIALS AND METHOD: This research was designed to be cross-sectional in nature where a convenience sampling of 70 interns, 88 post-graduate students and 49 faculty members of IDS Bareilly were selected. Questionnaires were self-administered and contained twelve points for job satisfaction (Minnesota Satisfaction Questionnaire), thirteen points for occupational stress and twelve for job performance
RESULTS: The subjects were moderately satisfied with their jobs, were less stressed and had a moderate job performance. After descriptive tests, the Chi-squared test, Pearson and Spearman Correlation Coefficient was applied to test statistical significance and p value was set to be significant at p<0.5.
DISCUSSION: The present study showed that most of the dentists (60.9%) had a high sense of heat and such results may be because of the current hospital framework which includes lack of air conditioners, continuous patient workload in hospital, high sense of heat among the dentists working in top floors etc.
CONCLUSION: If effective prevention measures are taken in the hospitals, dentists may perform more efficiently and also the increase the job satisfaction
The Impact of Using Social Media on Dental Treatment: An Online Survey
INTRODUCTION: Social media is a mode of communication that allows a person to create and share information with others. Facebook, WhatsApp, Twitter, Google+, YouTube etc are some examples of social media applications and they allow people to communicate across the world. There is very less literature available that shows the effect of social media in esthetics in India.
AIM: To conduct an online survey to see the impact of using social media on esthetic dental treatments.
MATERIALS AND METHOD: 477 questionnaires were returned with responses and the data was entered into the MS excel sheet. Descriptive statistics was used for the frequency distribution and Chi Square was applied for the statistical relationship between male and female variables (at 5% significance).
RESULTS: Four hundred seventy seven participants responded to this study through online forms. Most of the participants belonged to the age group of 26-35 years (n=256), followed by 18-25 years (n= 137), 36-45 years and > 45 years (n= 55 & 29 respectively). The response of females was high (63.5%) when compared to males.
CONCLUSION: Females tend to follow dentists more as compare to males on social media. In dental practice, social media has become a widely used for exchanging and obtaining information
Assessment of Knowledge and Attitude Towards Hepatitis B Infection Among Health-Care Professionals in A North Indian City
Introduction: Hepatitis B is an infection which occurs frequently worldwide. Hepatitis B virus is a DNA virus and is etiologically related to family Hepadnaviridae.Most of the cases of Hepatitis B virus infection do not have any symptoms when they are newly or chronically infected due to which there is silent spread of the infection which later causes serious liver disease. Incidence of the Hepatitis B virus infection among health-care professionals has been estimated to be 2–4 times more as compared to the general population.Aims: to assess the knowledge and attitude towards Hepatitis B infection among medical, dental, and nursing students in Bareilly city.Settings and Design: A cross-sectional observational study was conducted among the medical and nursing students of Rohilkhand Medical College and Hospital and dental students of Institute of Dental Sciences, Bareilly.Method and Materials: A self-reported questionnaire was distributed among all the students of the study who were present at the day.Statistical analysis used: p-value was calculated using Kruskal Walli’s ANOVA test. A p-value of 0.05 or less was used as cut off level for statistical significance.Results: Total 222 students were selected out of which 60 were medical, 60 were dental and 102 were nursing. In our study medical students had better knowledge, attitude towards Hepatitis B infection than dental and nursing students.Conclusions: None of the students of medical, dental, and nursing were fully aware on all aspects of Hepatitis B Virus infection and the vaccination status was found to be unsatisfactory which increased the risk to acquire Hepatitis B infection
Knowledge, Attitude and Practice Regarding Tobacco Cessation Methods among the Dental Professionals of Bareilly International University: A Cross-sectional Study
INTRODUCTION: In India, the percentage of deaths caused by tobacco smoking is anticipated to rise from 1.4 percent in 1990 to 13.3 percent by 2020.Health care experts have done their best to persuade and counsel users to quit the habit through their collaborative efforts. AIM AND OBJECTIVES: Assessment of dentistry students' attitudes and practices concerning tobacco cessation strategies, as well as the role of information in their promotion. MATERIALS AND METHODS: This cross-sectional survey was carried out at the Institute of Dental Sciences, Bareilly among the dental professionals, i.e. final year, interns, postgraduates students. The questionnaire was designed to test the knowledge, attitude, and practice of dental students regarding tobacco use. The self-administered survey included a set of questions. Descriptive statistics and Chi-square test had been used to test associations between their responses among age, qualification, and academic year using statistical package for social sciences (SPSS) version 22. RESULTS: A total of 300 surveys were sent out, with a 96.39 percent response rate. There were 54 percent females and 46 percent males among the 250 participants. Approximately 68 percent of people were between the ages of 20 and 23. In the current study, 32.4 percent were seeking MDS and 67.6 percent were pursuing BDS. Nearly half of those prefer to prescribe nicotine replacement therapy (NRT) as a cigarette cessation recommendation to patients, followed by self-quitting at 48% and pharmaceutical approaches at 1.2 percent. DISCUSSION: More than half of the respondents had an average level of awareness of smoking cessation therapies, and the majority of them had a favorable attitude toward their provision. As a result, it is important to persuade students to develop an interest in learning about tobacco quitting strategies
Decadal variations in NDVI and food production in India
In this study we use long-term satellite, climate, and crop observations to document the spatial distribution of the recent stagnation in food grain production affecting the water-limited tropics (WLT), a region where 1.5 billion people live and depend on local agriculture that is constrained by chronic water shortages. Overall, our analysis shows that the recent stagnation in food production is corroborated by satellite data. The growth rate in annually integrated vegetation greenness, a measure of crop growth, has declined significantly (p < 0.10) in 23 of the WLT cropland area during the last decade, while statistically significant increases in the growth rates account for less than 2. Inmost countries, the decade-long declines appear to be primarily due to unsustainable crop management practices rather than climate alone. One quarter of the statistically significant declines are observed in India, which with the world's largest population of food-insecure people and largest WLT croplands, is a leading example of the observed declines. Here we show geographically matching patterns of enhanced crop production and irrigation expansion with groundwater that have leveled off in the past decade. We estimate that, in the absence of irrigation, the enhancement in dry-season food grain production in India, during 1982-2002, would have required an increase in annual rainfall of at least 30 over almost half of the cropland area. This suggests that the past expansion of use of irrigation has not been sustainable. We expect that improved surface and groundwater management practices will be required to reverse the recent food grain production declines. © 2010 by the authors; licensee Molecular Diversity Preservation International, Basel, Switzerland
αA-Crystallin Peptide 66SDRDKFVIFLDVKHF80 Accumulating in Aging Lens Impairs the Function of α-Crystallin and Induces Lens Protein Aggregation
The eye lens is composed of fiber cells that are filled with α-, β- and γ-crystallins. The primary function of crystallins is to maintain the clarity of the lens through ordered interactions as well as through the chaperone-like function of α-crystallin. With aging, the chaperone function of α-crystallin decreases, with the concomitant accumulation of water-insoluble, light-scattering oligomers and crystallin-derived peptides. The role of crystallin-derived peptides in age-related lens protein aggregation and insolubilization is not understood.We found that αA-crystallin-derived peptide, (66)SDRDKFVIFLDVKHF(80), which accumulates in the aging lens, can inhibit the chaperone activity of α-crystallin and cause aggregation and precipitation of lens crystallins. Age-related change in the concentration of αA-(66-80) peptide was estimated by mass spectrometry. The interaction of the peptide with native crystallin was studied by multi-angle light scattering and fluorescence methods. High molar ratios of peptide-to-crystallin were favourable for aggregation and precipitation. Time-lapse recordings showed that, in the presence of αA-(66-80) peptide, α-crystallin aggregates and functions as a nucleus for protein aggregation, attracting aggregation of additional α-, β- and γ-crystallins. Additionally, the αA-(66-80) peptide shares the principal properties of amyloid peptides, such as β-sheet structure and fibril formation.These results suggest that crystallin-derived peptides such as αA-(66-80), generated in vivo, can induce age-related lens changes by disrupting the structure and organization of crystallins, leading to their insolubilization. The accumulation of such peptides in aging lenses may explain a novel mechanism for age-related crystallin aggregation and cataractogenesis
Second echelon node predicts metastatic involvement of additional axillary nodes following sentinel node biopsy in early breast cancer
BACKGROUND : In many patients with early breast cancer, the sentinel
lymph node (SLN) is the sole site of regional nodal metastasis. This
subgroup of patients may not benefit from completion axillary lymph
node dissection (CALND). AIMS: This pilot study evaluates the status
of 2nd echelon (station) lymph nodes in the axilla as a predictor of
additional positive nodes in the axilla in the presence of sentinel
node metastasis. SETTINGS AND DESIGN: Cross-sectional study of 40
breast cancer patients. MATERIALS AND METHODS: Forty patients with
invasive breast cancer underwent SLN biopsy followed by 2nd echelon
lymph node biopsy in the same sitting. SLN mapping was performed using
a combined technique of isosulfan blue and 99 mTc-sulfur colloid. SLNs
(Station I) were defined as blue and/or hot nodes. These nodes were
then injected with 0.1 ml of blue dye using a fine needle and their
efferent lymphatic was traced to identify the Station II nodes. Then a
complete ALND was performed. All the specimens were sent separately for
histopathological evaluation. RESULTS : SLNs (Station I nodes) were
successfully identified in 98% (39/40) patients. Of the 17 patients
with a positive SLN, 8 (47%) patients had no further positive nodes in
the axilla, 9 (53%) patients had additional metastasis in nonsentinel
lymph nodes upon CALND. Station II nodes were identified in 76% (13/17)
patients with a positive SLN. Station II nodes accurately predicted the
status of the remaining axilla in 92% patients (12/13). STATISTICAL
ANALYSIS : We calculated the Sensitivity, Negative predictive value,
Positive predictive value, False negative rate and Identification rate.
CONCLUSION : Station II nodes may predict metastatic involvement of
additional nodes in the axilla
Factors Influencing Households’ Intention to Adopt Solar PV : A Systematic Review
Rising energy needs, concerns of energy security, mitigating greenhouse gas emissions, climate change phenomenon and a push to utilize indigenous sources for energy generation purposes has encouraged the use of solar photovoltaics (PV). The technological advancements of the recent past, improvement in technologies’ performance, reduction in the prices, policy and regulatory support, and its applicability at household level has made solar energy as a preferred form of energy generation. However, despite its rapid diffusion, it is widely believed that its current application is insignificant compared to its potential. This leads us to ask why solar PV has not been adopted to the level it should have. The existing literature has highlighted a number of factors affecting solar PV adoption. This paper systematically reviews the literature to identify the factors that have been instrumental to solar PV adoption. By exploring the Scopus database, this research identifies 39 articles matching the study objectives. Findings of this research will help academics, technology companies and policymakers in understanding the factors influencing the process and proposing solutions to address these.©2020 Springer.
