Chronological course of wisdom teeth eruption in Croatian population

Dental age determination is required in various clinical and scientific disciplines. OBJECTIVES: The aim of this research was to estimate the chronological course of wisdom teeth eruption in Croatian Caucasian population. METHODS: The evaluated sample consisted of 1.249 orthopantomograms of Croatian Caucasian patients between 10 and 25 years and 530 males and 719 females in terms of gender. The following staging system was used for classification of wisdom teeth eruption from stage A: occlusal plane covered with alveolar bone to stage D: complete emergence in occlusal plane. RESULTS: The minimum age of occlusal plane covered (stage A) with alveolar bone was 10 years and mean age was 12.5 years for both genders. The corresponding standard deviation range was 1.5 years. The minimum age of alveolar emergence of wisdom teeth (stage B) was 12 years for females, and 12 to 13 years for males. The mean age of alveolar emergence ranged from 15.9 to 16.2 years for males and from 15.7 to 16.1 years for females. The corresponding standard deviation ranges were 1.8-1.9 and 1.9-2.2 years. In the stage C, the minimum age of gingival emergence in this study was 15 years for both genders. The corresponding standard deviation range was 2.0 – 2.2 years for males, and 2.2 years for females. In the stage D, the minimum age of complete emergence of the wisdom teeth in the occlusal plane was 17 years in both genders. The mean age of complete emergence ranged from 21 to 21.5 years for males and from 21.4 to 21.5 years for females. The corresponding standard deviation range was 1.7 – 1.9 years for males, and 1.9 – 2.0 years for females. CONCLUSION: The results on the emergence of wisdom teeth contribute to the forensic dentistry practice while determining the dental age at the same time.
