Comparison of developmental dental anomalies between Generations Y and Z in Türkiye: a retrospective panoramic
Objectives:
This study compared the prevalence and distribution of developmental dental anomalies between Generation Y (1980-1994) and Generation Z (1995-2015) individuals in Türkiye.
Method And Materials:
A retrospective analysis was performed using panoramic radiographs of 3,444 systemically healthy individuals between May 1998 and October 2024. Participants were divided by birth year into Generation Z (n = 2,544) and Generation Y (n = 900). Anomalies were categorized as size, shape, number, and position/eruption anomalies. Binary and multiple univariate logistic regression analyses were conducted using SPSS version 26.0 (IBM).
Results:
The overall prevalence of developmental dental anomalies was significantly higher in Generation Z (38.9%) compared to Generation Y (13.8%) (P .001). Shape anomalies were more prevalent in Generation Z (64.6%) than in Generation Y (43.4%) (odds ratio [OR] 1.645; 95% CI 1.112-2.432; P = .013), whereas number anomalies were more common in Generation Y (34.6%) than in Generation Z (15.1%) (OR 0.484; 95% CI 0.305-0.770; P = .002). No significant differences were observed for size or position/eruption anomalies (P = .640 and .416, respectively). Among specific anomalies, taurodontism was significantly more prevalent in Generation Z (22.6%) compared to Generation Y (3.7%) (P .001), while hypodontia was more prevalent in Generation Y (30.6%) than Generation Z (10.6%) (P = .002).
Conclusion:
This study revealed distinct generational differences in developmental dental anomalies, suggesting possible associations between temporal and environmental factors on dental development. These findings may assist clinicians, researchers, and educators in adopting more generation-specific diagnostic and preventive approaches and in achieving better prediction of potential complications in clinical practice.
