METHODS: Digital panoramic radiographs belonging to 253 patients aged between 18-35 years old were examined. According to the inclusion criteria of the study, a patient and control group was formed. The patient group (n=46) included individuals having at least one extracted tooth in the posterior region of the mandible, and the control group (n=45) included full dentate patients. The MI and PMI (PMI-i and PMI-s) were calculated bilaterally for all of the individuals.
RESULTS: No significant difference was found between the MI, PMI-i and PMI-s indices of the patient group and the control group among both genders.
CONCLUSIONS: The mandibular premolar and/or molar teeth loss in young adults did not lead to any change in the MI, PMI-i and PMI-s indices among both genders.
方法:检查了253名年龄在18-35岁之间的患者的数字全景X射线照片。根据本研究的纳入标准,形成患者和对照组。患者组(n=46)包括在下颌骨后部区域至少有一颗拔牙的个体,对照组(n=45)包括完整齿状患者。双侧计算所有个体的MI和PMI(PMI-i和PMI-s)。
结果:在MI之间没有发现显着差异,两种性别中患者组和对照组的PMI-i和PMI-s指数。
结论:年轻人的下颌前磨牙和/或磨牙缺失没有导致MI的任何变化,两种性别的PMI-i和PMI-s指数。
