Abstract
Objective: The aim of study is to examine the interest in orthodontics in the last 5 years using Google Trends data all over the world. Materials and Methods: On July 6, 2020, the Google Trends application was searched for the last five years. Search results were recorded separately for all keywords and separately for 26 countries with sufficient data. The mean of all search results is taken and a Google Trends Value (GTV) is obtained for the countries. These data are correlated with population, Gross Domestic Product (GDP) and knowledge of English (English Proficiency Index – EPI) in countries. Pearson correlation test was used for correlation values between Population, GDP and EPI with Google Trend values. Results: According to the table, the highest GTV were observed in United States (65.33); lowest GTV were observed in France. According to the statistically analysis, a positive correlation was found between GTV with both population and GDP and EPI values. Finally, a positive correlation was found between GDP and EPI values and this positive correlation was statistically significant(p<0.05). Conclusion: No significant relationship was found between the interest in orthodontics and the population. There is a significant positive correlation between the Gross National Product and the level of knowledge of English.
