基于影像学分析的儿童上颌前牙区多生牙对恒牙萌出影响的临床研究
A clinical study on the impact of supernumerary teeth in the anterior maxillary region on permanent tooth eruption in children
摘要
Abstract
Objective:To investigate the clinical characteristics of supernumerary teeth in children and their impact on the eruption of permanent teeth.Methods:A retrospective analysis was conducted on the clinical features of 132 pediatric patients(184 supernumerary teeth)and their effect on the eruption of permanent teeth.Results:The majority of patients were aged 7～9 years(53.03%),with a higher prevalence in males(approximately 4∶1).Most cases had a single supernumerary tooth(61.36%),with the teeth predominantly located on the palatal side(80.43%),inverted(47.28%),and conical in shape(62.50%).Most supernumerary teeth were unerupted(76.63%).32 teeth(17.39%)caused delayed eruption/impaction,43 teeth(23.37%)led to displacement,18 teeth(9.78%)caused rotation,and 31 teeth(16.85%)resulted in midline diastema.Supernumerary teeth located within the dental arch were more likely to cause rotation of permanent teeth(25.00%)(P<0.05).The tuberculate type was more frequently associated with displacement(44.23%)and rotation(21.15%)of permanent teeth(P<0.05).In contrast,orientation,eruption status,and distance from the permanent tooth germ showed no statistically significant association with eruption abnormalities(P>0.05).Conclusion:Supernumerary teeth can lead to eruption abnormali-ties of permanent teeth.Early imaging screening and intervention are crucial for preventing malocclusion.关键词
