摘要
目的:应用锥形束CT(CBCT)分析多生牙相关特征,为临床诊疗提供参考。方法:选择2019年1月—2020年12月内蒙古医科大学附属医院口腔科经CBCT确诊的234颗多生牙作为研究对象,分析其生长发育特征及继发影响。采用SPSS 25.0软件包对数据进行统计学处理。结果:患者平均年龄11.16±7.61岁,以7~12岁最多。男女比例为1.6∶1。汉族占85.0%。多数单侧生长,数量多为1颗。多生牙生长区域多数为上颌骨切牙区,下颌骨前磨牙区。切牙区多生牙多见于7~12岁,尖牙区和前磨牙区多见于13~18岁,磨牙区多见于≥19岁。切牙区多生牙好发于男性,以圆锥形为主;其余区域多生牙好发于女性,以结节形为主,差异均有统计学意义(P<0.05)。发育情况为≥19岁年龄组高于其他3组,磨牙区高于其他区域,上颌骨高于下颌骨,差异均有统计学意义(P<0.05);位于两恒牙牙根之间的多生牙高于其他3组,差异无统计学意义(P>0.05)。萌出情况为部分牙根形成和完全形成高于牙冠形成,正向高于其他方向;位于两恒牙牙根之间的多生牙高于其他3组,差异均有统计学意义(P<0.05)。继发影响为各生长区域及位于恒牙唇侧、根尖部和两恒牙牙根之间的多生牙主要影响邻近恒牙,位于恒牙腭侧的多生牙多数无继发影响,差异均有统计学意义(P<0.05)。结论:CBCT可精确分析多生牙相关特征,利于临床制定完善诊疗方案,提高治疗效果。
PURPOSE:Cone-beam CT(CBCT)was used to analyze the related characteristics of supernumerary teeth and provide more reference for clinical diagnosis and treatment.METHODS:A total of 234 multiple teeth diagnosed by CBCT from the Department of Stomatology,Affiliated Hospital of Inner Mongolia Medical University from January 2019 to December 2020 were selected as the research subjects.The growth and development characteristics and secondary effects of supernumerary teeth were analyzed with SPSS 25.0 software package.RESULTS:The average age of patients was 11.16±7.61 years old,with the largest number of patients in the age group of 7-12 years old.The male to female ratio was 1.6∶1.Han nationality accounted for 85.0%.The supernumerary teeth were mainly unilateral.The quantity was mostly one.Maxillary supernumerary teeth mainly occurred in the incisor area,while mandibular supernumerary mainly occurred in the premolar area.Maxillary supernumerary teeth in the incisor area was more common in the age group of 7-12 years old,while those in the canine and premolar area were more common in the age group of 13-18 years old,those in the molar area were more common in the age group over 19 years old.Supernumerary teeth in the incisor area was more likely to occur in males,and mainly conical;the remaining of the growth areas were more likely to occur in females and mainly nodular.The differences were statistically significant(P<0.05).Development status in the age group over 19 years old was better than the other three groups;the molar area was better than other areas;the maxilla was better than the mandible;the differences were statistically significant(P<0.05).The supernumerary teeth located between the roots of the two permanent teeth were better than the other three groups,the difference was not statistically significant(P>0.05).The eruption situation was that partial root formation and fully formed supernumerary teeth were higher than crown formation,positive growth was higher than other directions,supernumerary teeth located between the roots of two permanent teeth were higher than the other groups.The differences were statistically significant(P<0.05).The secondary effects were that supernumerary teeth located in each growth area and located on the labial side,the apex of the permanent teeth and between the roots of the two permanent teeth mainly affect the adjacent permanent teeth,and most of the supernumerary teeth located on the palatal side of the permanent teeth have no secondary effects.The differences were statistically significant(P<0.05).CONCLUSIONS:CBCT can accurately analyze the clinical characteristics of supernumerary teeth,which is beneficial to formulate and improve the diagnosis and treatment plan and improve the treatment effect.
