Author: Abhishek Meshram (90)
Introduction:
Toothpaste is an essential oral care product used to maintain dental hygiene and prevent problems such as cavities, bad breath, and gum disease. It helps in cleaning teeth, removing plaque, and strengthening enamel. In India, a wide variety of toothpaste brands are available to meet different oral care needs, such as whitening, herbal protection, and cavity prevention. Popular brands like Colgate, Dabur, Close-Up, and Patanjali are commonly used. This research focuses on understanding different toothpaste brands, their effectiveness, and consumer preferences.
Objective:
To determine which toothpaste brands are most popular among consumers.
Literature Review:
Factors Affecting Purchase Decision
Patel (2021) identified price, product quality, packaging, and advertising as the key determinants of toothpaste purchasing behaviour. The study emphasized that advertising significantly influences consumer perception and plays a vital role in building brand image and attracting customers.
Brand Awareness and Loyalty
Sharma (2019) found that brand awareness and brand loyalty play a crucial role in influencing consumer purchasing decisions. The study revealed that consumers tend to prefer familiar toothpaste brands and are less likely to switch unless there are strong promotional offers or innovative product features introduced in the market.
Data Collection:
The study was conducted to compare the ratings of four toothpaste brands—Colgate, Dabur, Close-Up, and Patanjali—based on student preferences. A Google Form survey was used to collect data, where 30 students rated each toothpaste on a scale of 1 to 10 according to their experience or liking. All responses were recorded in a spreadsheet, resulting in a total of 120 ratings, with 30 ratings for each brand.

The collected data were analyzed using single-factor ANOVA to determine whether there were significant differences among the average ratings of the four toothpaste brands. The mean ratings were 7.3 for Colgate, 6.4 for Dabur, 6.5 for Close-Up, and 5.167 for Patanjali, with variances ranging from 6.907 to 8.455.
The ANOVA results showed an F-value of 3.0094, which is greater than the critical F-value of 2.6828, and a P-value of 0.0331, which is less than the significance level of 0.05. These results indicate that the differences between the toothpaste ratings are statistically significant.
Conclusion:
Based on the analysis, there is a significant difference in the ratings of the four toothpaste brands. Among them, Colgate has the highest mean rating, while Patanjali has the lowest. Since the differences are statistically significant, it can be concluded that consumers have clear preferences among the brands, with Colgate being the most preferred in this study.
