Literature review
Quality Test —
Shree Ram Khanna (2019), stated that while testing the brands no stipulations have been made regarding the composition of toothpastes, it is essential that toothpaste formulation should not contain any ingredient that may cause a toxic or irritating reaction when used in the mouth, nor shall it be harmful in normal use, keeping in mind that small amount may be ingested inadvertently.We can examine the brandwise ratings on Individual parameters as well. In the testing it was analyzed that all brands fulfill all requirements specified in the Indian Standard. All brands performed well on quality parameters such as pH, fluoride ion, fineness, stability, dispensing and inertness. Nicotine was not found in any of the tested brands. Pepsodent was found to have the highest foaming power. All brands passed in the microbiological and heavy metal tests.

Consumer Behavior —
G. Vani, (2010), States that this study revealed that consumer awareness of toothpaste is less in Bangalore city. Oral care market offers huge potential as penetration and per capita consumption of oral care products is very low in India. However, rising per capita income and increasing awareness is driving demand for oral care products, the dentist population is also low in India. For promoting the product consumption and creating awareness the government has taken initiatives like dental health camps. Manufacturers have used advertising campaigns to promote higher consumption of toothpaste. Creating awareness is a part of the social responsibility of the company. There are some important factors considered by the consumer for decision making. Brand image, advertising, and offer play an important role in purchasing toothpaste, sometimes based on the offer the consumer compares with competitor products and select the best one. Switching of one product to another company is mainly based on advertisement, brand name, packaging availability, and price rise, etc. So the companies analyze all these factors and find out the best suitable tools for promoting their toothpaste in India.

Data collection
I choose four brands on which I will make my analysis. Then I made a google form asking them to rate them on 1 to 10 scale. The form was filled by 30 people and their feedback was then collected in an Excel Sheet. The data were analyzed by the ANOVA (Single Factor) method. By analysing the values we came to the conclusion.

Data analysis
Between Groups — 21.09 (SS), 3(DF)
Within Groups — 191.5 (SS), 116(DF)
F-value — 4.26
P-Value — 0.01

The calculated value of F(3,116) is 4.25 at 0.05 level of significance and the tabulated value of F(3,116) is 2.68 at 0.05 level of significance, therefore calculated value of F is greater than the tabulated F value hence we reject the null hypothesis and accept the alternative hypothesis that means we can conclude there is a significant difference in the mean of this products.
