RESUMO
Background: Anaemia is a major health problem creating an extreme burden on public health, especially in developing countries. Globally, anaemia affects 1.62 billion people, which corresponds to 24.8% of the population. The government of India is implementing various programs to bring down the prevalence of anaemia including iron and folic acid supplementation to school going children. This study attempts to assess the prevalence of anaemia among school going children of first to the tenth standard, in rural and urban areas of Mysore and Chamarajanagara districts of southern part of Karnataka state, India.Methods: A cross sectional study was conducted in 50 selected schools of Mysore and Chamarajanagara districts for a period of one academic year, and 8719 students were evaluated for anaemia. The data was analyzed using appropriate software and statistical methods.Results: The prevalence of anaemia among school going children in Mysore and Chamarajanagar districts was 27.6%. While 22.7% of the girls showed the signs of anaemia, only 19.2% of boys showed anaemia. The prevalence of anaemia was high in rural areas than urban areas and maximum prevalence was seen among high school students followed by upper primary school students and lower primary school students.Conclusions: The total prevalence of anaemia among school children in Mysore and Chamarajanagara districts was 27.6%. The prevalence of anaemia was below the currently available national standards. This low prevalence could be attributed to the continuing care with yearly screening and iron and folic acid tablets provided to the study population under National Health Mission.
RESUMO
Background: Dentin hypersensitivity (DH) affects all age groups in a population and is perceived as pain to any stimuli. From time immemorial, researchers have sought herbal or natural solutions to treat hypersensitivity. Propolis is one such natural, nontoxic resinous substance produced by honey bees, which is useful in various applications in dentistry and effective in treating dentinal hypersensitivity. Aim: The aim of this in vitro study is to assess the effect of propolis varnish on occlusion of dentinal tubules thus aiding in the treatment of dentinal hypersensitivity. The objective is to evaluate the effectiveness of the proposed treatment using scanning electron microscope (SEM) imaging. Materials and Methods: Twenty naturally extracted teeth were collected and stored until in vitro assessment. Discs obtained from each tooth were divided into two groups of 20 each – I (test) and II (control), with each tooth acting as its own control. Propolis varnish was applied only to the acid-etched surface of the exposed dentin of discs in the test group, whereas all the discs were subjected to SEM imaging. Results: Statistical analysis showed a significant reduction in open tubules (P < 0.001) from 160 ± 6.97 before treatment to 61.20 ± 9.10 after propolis varnish application in the test group. Conclusion: This study showed the promise of propolis varnish as a natural treatment modality for DH.
