Introduction: Contamination of a surface occurs by microorganisms when it inhabits any surface or an object when the count of the bacteria increases. The degree of contamination can be estimated by counting the number of colonies, when a sample collected from that site is cultured. Streptococcus mutans is considered to be the normal commensal of our oral cavity. When it’s count is increased in the oral cavity, it causes dental caries and other tooth related problems. The main aim of this study is to estimate the bacterial contamination in the tooth brush head used by students for varying time periods.
Materials and Methods: Used toothbrushes for varying time periods are collected from students. Then their bristles are plucked with the sterilized forceps for the prevention of bacterial contamination and agitated in the saline and inoculated in the brain heart infusion broth agar with the help of sterilized bacterial loops and incubated for 24 hours at 37oC. Then the colonies are counted and record as CFU/ml.
Results: The bacterial count is directly proportional to period of usage, but it is affected by certain factors like duration of brushing and using brushes. On an average the count was estimated to be 47 CFU/ml for two months, 57 CFU/ml for six months, 68 CFU/ml for eight months and 81 CFU/ml for a year. The p1 value (for sample 1 and 2) was 0.046 (p<0.05), so it is statistically significant.
Conclusion: The study shows that in prolonged usage of tooth brushes the bacterial contamination also increases. So the tooth brushes should be protected in tooth brush holders, to avoid contamination and the toothbrushes should be changed once in a month for betterment of oral health.
Coronavirus disease [Covid 19] is an infectious communicable disease causing severe causality among the world’s population. A communicable disease with high intense spread rates originated from China. As a result the world has locked all its gates, prevails in the entire world. Economy the most affected sector in any country, daily life living is now restricted. The main aim of this study is to test the knowledge and create awareness on various attributes that are related to the Indian economy among the Trichy population. A self assessed questionnaire containing 14 questions about Indian economy during COVID 19 were framed and was shared through an online survey platform. The questionnaire was passed to 109 individuals. Responses from them were collected and were through SPSS. Many residents from Trichy are aware about various aspects that affect our economy. Most of the responses from them were relevant and correct, emphasizing that they are already aware in these fields. Pandemic plays an important role in deciding a country’s economy. It shows its effects on all sectors of the government. Measures should be adopted by the citizens in order to escape from this economic fever.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
