下颌智齿萌出较晚且常阻生,阻生齿更易继发冠周炎及诱发龋齿,在治疗上多需拔除,但阻生齿在形态上变异较大,术中往往遇有一些困难,为了解下颌智齿的形态,我们共收集了拔除后的下颌阻生智齿490颗,正常位智齿300颗加以对比: 牙根数比较:490颗阻生智齿和300颗正常位智齿牙根数的比较是不完全相同的,后者之单根牙有91颗,占33.33%。前者单根牙有94颗,
Mandibular wisdom tooth eruption later and often impacted, impacted teeth more likely to secondary pericoronitis and induced dental caries, in the treatment of more removal, but the morphological variability of impacted teeth larger, often encountered some difficulties in surgery, as To understand the morphology of the mandibular wisdom teeth, we collected a total of 490 mandibular impacted wisdom teeth, compared with 300 wisdom teeth: Comparison of the number of teeth: The comparison of 490 impacted wisdom teeth and 300 normal wisdom teeth is not complete The same, the latter single tooth 91, accounting for 33.33%. The former single root teeth 94,
