| Popis: | Aim: The aim of the current study is to correlate the presence of tooth agenesis with other dental anomalies in 7- to 15-year-old patients. Materials and methods: After evaluating 4000 panoramic radiographs of young subjects, 430 revealed the presence of tooth agenesis, except for the third molar, and are retrospectively observed and compared with a non-agenesis control group of 500 subjects, in order to investigate the existence of other associated dental anomalies in both groups. Results: The prevalence of tooth agenesis was approximately 9.30% (430/4000); no significant gender differences were found. A significantly higher prevalence of microdontia of the maxillary lateral incisors (p < 0.001) and delayed tooth development (p = 0.0001) was observed in the agenesis group (group A), while delayed development of permanent teeth (p < 0.0001) and hypo-occlusion of the primary molars (p = 0.0130) were found in the control group (group B). Conclusions: Agenesis patients presented a significantly higher prevalence of microdontia of the maxillary lateral incisors. Instead, non-agenesis patients presented a high prevalence of delayed permanent tooth development and hypo-occlusion of the primary molars. Moreover, further researches are needed to elucidate the role of genetics and environmental factors in the current sample group. |
