BACKGROUND
The aim of this study was to know the distribution of dental developmental alterations in the population requesting stomatological attention at the Admission and Diagnosis Clinic of our institution in Mexico City.
MATERIAL AND METHODS
We reviewed the archives and selected those files with developmental dental alterations. Analyzed data were diagnoses, age, gender, location and number of involved teeth.
RESULTS
Of the 3.522 patients reviewed, 179 (5.1%) harbored 394 developmental dental alterations. Of them, 45.2% were males and 54.8% were females with a mean age of 16.7 years. The most common were supernumeraries, dental agenesia and dilaceration. Adults were 30.7% of the patients with dental developmental alterations. In them, the most common lesions were agenesia and supernumeraries. Mesiodens was the most frequently found supernumerary teeth (14.7%).
CONCLUSIONS
Our finding that 30.7% of the affected patients were adults is an undescribed and unusually high proportion of patients that have implications on planning and prognosis of their stomatological treatment.
背景
本研究的目的是了解在墨西哥城我们机构的入院与诊断诊所寻求口腔治疗的人群中牙齿发育异常的分布情况。
材料与方法
我们查阅了档案，挑选出有牙齿发育异常的病例。分析的数据包括诊断结果、年龄、性别、受累牙齿的位置和数量。
结果
在查阅的3522例患者中，179例（5.1%）存在394处牙齿发育异常。其中，男性占45.2%，女性占54.8%，平均年龄为16.7岁。最常见的是多生牙、牙齿缺失和牙折。成人占牙齿发育异常患者的30.7%。在成人中，最常见的病变是牙齿缺失和多生牙。正中牙是最常发现的多生牙（14.7%）。
结论
我们发现30.7%的受影响患者为成人，这一比例未被描述且异常高，对其口腔治疗的规划和预后有影响。
