【摘要】：目的应用锥形束CT(CBCT)观测江西成年人群下颌骨体副孔的分布位置,为临床安全操作提供依据。方法选取200份江西成年人的CBCT资料,按年龄分为4组,每组男女比例相等。描述下颌骨前牙、前磨牙和磨牙各区域的副孔数目和分布位置,分析年龄、性别和左右侧因素与副孔发生率的关系。结果发现下颌骨体副孔共1 123个,人均(5.62±2.10)个。副孔发生率自近中区域向远中降低,舌侧副孔发生率高于颊侧,男女性副孔数目无差异(P=0.195),年龄与副孔数目呈负相关(rs=-0.301)。下颌骨体三处副孔高频区域为:正中联合部(98.0%),中、侧切牙牙槽突舌侧(88.0%),前磨牙区的低位(55.0%)。结论下颌骨副孔每人均会出现,临床需留意避免损伤副孔内容物而引起并发症。
[Abstract]:Objective to observe the distribution of mandibular accessory foramen in Jiangxi adult population by conical beam CT (CBCT), and to provide evidence for clinical safety. Methods the CBCT data of 200 Jiangxi adults were divided into 4 groups according to their age. The number and distribution of accessory foramen in each region of mandibular anterior teeth, premolars and molars were described, and the relationship between the incidence of accessory foramen and age, sex, left or right side was analyzed. The results showed that there were 1 123 foramen accessory to the mandible, with a per capita number of (5.62 卤2.10). The incidence of accessory foramen decreased from near to middle region to far away, and the incidence of lingual accessory foramen was higher than that of buccal side. There was no difference in the number of accessory foramen between male and female (P < 0. 195). The age was negatively correlated with the number of accessory foramen (rs=-0.301). The high frequency regions of the three accessory foramen in the mandibular body were as follows: the median joint (98.0%), the lateral incisor (88.0%) and the premolar region (55.0%). Conclusion the accessory foramina of mandible will appear in every patient, and the complications caused by injury of the contents of accessory foramen should be avoided in clinic.
