Abstract

Amaçlar: Bu çalışma, 2015-2025 yılları arasında seçilen G7 (Amerika Birleşik Devletleri, Kanada, Birleşik Krallık) ve E7 (Türkiye, Brezilya, Hindistan) ülkeleri arasında endodontist ile ilgili Google Trends™ (GT) arama hacimlerini karşılaştırmayı ve arama ilgisi ile kişi başına düşen gayri safi yurtiçi hasıla (GSYİH) arasındaki ilişkiyi değerlendirmeyi amaçlamıştır.
Yöntemler: 2015-2025 dönemi için “endodontist” terimi ve her ülkenin yerel dilindeki karşılıkları için GT arama indeksleri elde edildi. Aylık arama değerleri nüfusa göre standardize edildi ve “10 milyon nüfus başına arama indeksi” olarak ifade edildi. Yıllık kişi başına düşen GSYİH ve ulusal nüfus verileri, kamuya açık uluslararası veri tabanlarından elde edildi. İstatistiksel analizler, grup karşılaştırmaları için t-testleri, ülke düzeyindeki farklılıklar için post-hoc testli tek yönlü ANOVA ve arama indeksi ile kişi başına düşen GSYİH arasındaki ilişki için Pearson korelasyon analizini içeriyordu. Anlamlılık düzeyi α=0,05 olarak kabul edildi.
Sonuçlar: G7 ülkeleri, E7 ülkelerine kıyasla önemli ölçüde daha yüksek standartlaştırılmış arama hacimleri göstermiştir (ortalama fark: 10,82; p<0,001). İkili karşılaştırmalar, Amerika Birleşik Devletleri ve Brezilya hariç tüm ülke çiftlerinin önemli ölçüde farklı olduğunu göstermiştir (p=0,899). Arama hacmi ile kişi başına düşen GSYİH arasında genel olarak zayıf ila orta düzeyde pozitif bir korelasyon gözlemlenmiştir (r=0,328, p=0,016). Bununla birlikte, alt grup analizi, E7 ülkelerinde güçlü bir pozitif korelasyon (r=0,855, p<0,001) ve G7 ülkelerinde orta düzeyde negatif bir korelasyon (r=−0,574, p=0,002) ortaya koymuştur.

Sonuç: Endodontistlere olan kamu ilgisi ülkeye göre önemli ölçüde değişmekte ve sosyoekonomik durumdan etkilenmektedir. Kişi başına düşen daha yüksek GSYİH, E7 ülkelerinde arama ilgisinin artmasıyla ilişkilendirilirken, G7 ülkelerinde bunun tersi bir eğilim gözlemlenmiştir. GT, kamuoyu farkındalığını izlemek ve endodontik bakımda kaynak tahsisini bilgilendirmek için değerli bir dijital epidemiyolojik araç olarak hizmet edebilir.

Abstract

Aims: This study aimed to compare endodontist-related Google Trends™ (GT) search volumes between selected G7 (United States, Canada, United Kingdom) and E7 (Turkiye, Brazil, India) countries from 2015 to 2025, and to evaluate the relationship between search interest and gross domestic product (GDP) per capita.
Methods: GT search indices for the terms “endodontist” and their equivalents in each country’s native language were retrieved for the period 2015–2025. Monthly search values were standardized by population and expressed as “search index per 10 million population.” Annual GDP per capita and national population data were obtained from publicly available international databases. Statistical analyses included t-tests for group comparisons, one-way ANOVA with post-hoc testing for country-level differences, and Pearson correlation analysis for the association between search index and GDP per capita. A significance level of α=0.05 was adopted.
Results: G7 countries demonstrated significantly higher standardized search volumes compared with E7 countries (mean difference: 10.82; p<0.001). Pairwise comparisons showed that all country pairs differed significantly except the United States and Brazil (p=0.899). A weak-to-moderate positive correlation was observed between search volume and GDP per capita overall (r=0.328, p=0.016). However, subgroup analysis revealed a strong positive correlation in E7 countries (r=0.855, p<0.001) and a moderate negative correlation in G7 countries (r=−0.574, p=0.002).
Conclusion: Public interest in endodontists varies substantially by country and is influenced by socioeconomic status. While higher GDP per capita was associated with increased search interest in E7 countries, the opposite trend was observed in G7 nations. GT may serve as a valuable digital epidemiological tool to monitor public awareness and inform resource allocation in endodontic care.
