This study aimed to evaluate the relationship between the calcification stages of permanent maxillary and mandibular canines and second premolars and skeletal maturity in both sexes.
This study included 138 patients (82 females, 56 males) who were treated in the Department of Orthodontics, Altınbaş University. The mean age of the patients was 12.31±1.76 years, ranging from 7.8 years to 15.8 years. Dental maturity stages of canines and second premolars were evaluated according to the Demirjian index on digital panoramic radiograph. The skeletal maturation stage was determined using the cervical vertebral maturation (CVM) index. The Pearson correlation analysis was performed to assess the association among CVM stages and calcification stages of canines, second premolars, sex, and chronological ages.
A statistically significant correlation was found between CVM and the calcification stages of the canines and second premolars (p<0.05). The calcification stages of the canines and second premolars had the highest distribution of Stage F and Stage G at CVM2 (p<0.01). For the canines and second premolars, Stage H corresponded to CVM3 in female patients and a high percentage of Stage G corresponded to CVM3 in the male group.
A significant correlation was found between the calcification stages of maxillary and mandibular canines, second premolars, and skeletal maturity in both sexes. It was observed that calcification stages and cervical maturations were advanced in female subjects compared with male subjects.
本研究旨在评估恒牙上颌尖牙、下颌尖牙及第二前磨牙的钙化阶段与男女骨骼成熟度之间的关系。
本研究纳入了138例在阿尔廷巴斯大学正畸科接受治疗的患者(82例女性,56例男性)。患者的平均年龄为12.31±1.76岁,年龄范围为7.8岁至15.8岁。根据数字全景X线片上的德米尔坚指数评估尖牙和第二前磨牙的牙齿成熟阶段。使用颈椎成熟度(CVM)指数确定骨骼成熟阶段。进行Pearson相关性分析以评估CVM阶段与尖牙、第二前磨牙的钙化阶段、性别及实际年龄之间的关联。
发现CVM与尖牙和第二前磨牙的钙化阶段之间存在统计学显著相关性(p<0.05)。在CVM2阶段,尖牙和第二前磨牙的钙化阶段F和G分布最高(p<0.01)。对于尖牙和第二前磨牙,女性患者中阶段H对应于CVM3,男性组中高比例的阶段G对应于CVM3。
发现男女上颌尖牙、下颌尖牙、第二前磨牙的钙化阶段与骨骼成熟度之间存在显著相关性。观察到女性受试者的钙化阶段和颈椎成熟度比男性受试者更超前。
