Sažetak
Objective: Prevalence of hypodontia was investigated in orthodontic patients from two 400 km distant Croatian regions: the City of Zagreb and Split-Dalmatia County. Methods: Study included 501 orthodontic patients older than 12 years: 257 from Zagreb (90 males and 167 females) and 244 from Split-Dalmatia County (107 males and 137 females). Diagnosis of hypodontia was based on the analysis of orthopantomograms and dental records. Results: Hypodontia was found in 31.52% individuals in Zagreb and 32.79% in SplitDalmatia County. With exclusion of third molars, the prevalence was 10.50% individuals in Zagreb and 12.29% in Split-Dalmatia County, 11.38% in both regions together. The most frequently missing tooth was the upper third molar (19.36%), followed by lower third molar (16.17%), second lower premolar (6.19%) and upper lateral incisor (4.19%). Upper jaw was more frequently affected than the lower. Bilateral hypodontia was more common for all genetically unstable teeth except the lower central incisor. There was no significant difference between the sexes nor between left and right sides. Other authors found lower prevalence and significant differences between Croatian regions: Istra 6, 25%, Slavonija 2, 34% (Legović et al. 1990) ; Zadar 5, 52% (Visković et al. 1988). Conclusion: Relatively high prevalence of hypodontia was found in both regions, slightly lower in Zagreb. The comparison with the other authors’ findings indicates significant regional differences are possible. Similar prevalence in the two investigated distant regions indicates inhomogeneity of Zagreb population, considering that residents from all regions have been moving to the capital of Croatia for centuries, including from Dalmatia.
