Objective: To analyse of the average annual percent change (AAPC) of registered dental patients, patients with preventive dental care and patients requiring dental treatment in the period of 2014-2016 in the Slovak Republic. Material and Methods: Data from registered dental patients (n=14,736,888), patients with preventive dental care (n=8,212,441) and patients requiring dental treatment (n=5,262,323) in the period of 2014-2016 were obtained from the Statistical Office of the Slovak Republic; 28,211,652 dental patients were analysed. The Theil-Sen estimator of trend line based on median and its significance was tested by nonparametric Wilcoxon test using statistical software R package. Results: The significant decrease (-4.11%) of the AAPC rates of registered dental patient (p<0.05) during the entire period (2014-2016) can be observed in age subcategory 15-18 years, while in age subcategory 19+ years the non-significant increase (1.08%) of the AAPC rate of registered dental patients in the same period was achieved. In the period of 2014-2016, the highest AAPC rate of patients with preventive dental care with the significant decrease was found in age subcategory 6-14 years (-17.19%; p<0.001). The AAPC rate of patients requiring dental treatment proved the significant negative values in age subcategory 0-5 years (-7.26%; p<0.01), in age subcategory 6-14 years (-9.33%; p<0.001), in age subcategory 15-18 years (-8.81%; p<0.01). Conclusion: The highest decrease AAPC rate of registered dental patients was observed in age subcategory 15-18 years. The statistical significant decrease AAPC rate of patients with preventive dental care was found in children ≤ 18 years. In patients requiring dental treatment (≤ 18 y.) was observed decrease AAPC rate.
