摘要:

目的:探讨多生牙的临床及三维影像学特征,为临床诊治提供依据。方法:选取2016年1月—2020年12月赤峰学院附属医院经锥形束CT(cone beam computed tomography,CBCT)检查有多生牙的患者,对患者性别、年龄、多生牙数目、位置、形态、方向、长度、多生牙与邻近牙齿和周围解剖结构的关系,以及有无继发影响等结果进行分析。结果:从4 555例受试者中筛选出362例上颌前牙区多生牙患者,发生率为7.95%,共诊断出488颗多生牙。男性多于女性,男女比例为2.85∶1,患者多为替牙期就诊(54.42%)。大多数上颌前牙区多生牙是单发的(66.85%),多位于中线区及双侧上颌中切牙附近(92.42%)。上颌前牙区多生牙多为锥形(88.73%)、正位(37.14%)、埋伏阻生(73.16%),24.80%的多生牙累及切牙管,多生牙平均长度为11.69 mm。与上颌前牙区多生牙有关的并发症主要包括邻牙异位萌出(20.49%)及上颌中缝位置的牙列间隙(18.85%)。结论:本地区上颌前牙区多生牙具有地域性特点,可为临床诊疗提供参考,CBCT能够准确分析多生牙的位置及继发影响,为手术提供依据。

Abstract:

Objective: To investigate the clinical and radiographic features of supernumerary teeth, and to provide evidence for clinical diagnosis and treatment. Methods: Patients diagnosed with supernumerary teeth were examined by cone beam computed tomography(CBCT) in Affiliated Hospital of Chifeng University from January 2016 to December 2020 were enrolled. The gender, age, number of supernumerary teeth, location, shape, direction, length, relationship of supernumerary teeth with adjacent teeth and surrounding anatomical structures, and secondary effects or not were examined. Results: A total of 362 patients with supernumerary teeth in maxillary anterior area were selected from 4 555 subjects with a 7.95% incidence rate, and a total of 488 supernumerary teeth were identified. Male patients were more than female patients, with a ratio of 2.85∶1. Most supernumerary teeth appeared in the dental replacement stage (54.42%). Most of the supernumerary teeth in the maxillary anterior area was solitary (66.85%), and located in the midline and bilateral maxillary central incisors region (92.42%). The supernumerary teeth in the maxillary anterior area was conical in shape (88.73%), anteroposterior positioned (37.14%), impacted (73.16%). 24.8% of the supernumerary teeth involved the canalis incisivus, and the average length was 11.69 mm. Complications mainly included ectopic protrusion of adjacent teeth (20.49%) and interdental space at maxillary central suture(18.85%). Conclusions: The supernumerary teeth in the maxillary anterior area have regional characteristics, which can provide reference for clinical diagnosis and treatment. CBCT can accurately analyze the location of supernumerary teeth and their secondary effects, and provide a basis for odontotomy.
