Background and objective Occlusion rehabilitation and restoration are difficult in subjects with congenitally missing lateral incisors, either unilaterally or bilaterally, and often lead to malocclusion and warrant replacement. The present study was conducted to assess the agenesis of maxillary lateral incisor unilaterally and bilaterally and to examine tooth size discrepancy in agenesis subjects undergoing orthodontic treatment. Materials and methods We assessed 32 dental casts of both genders (17 males and 15 females) with missing maxillary lateral incisors either unilaterally or bilaterally. Mesiodistal dimensions were measured and a comparison of tooth sizes was done for control and test groups. The data were assessed and the results were documented. Results Lateral incisors of the maxillary arch were statistically smaller in the test group compared to the control group. This was true for both males and females (p=0.001 for both). A similar finding was observed with respect to the overall study group (p<0.0001). Conclusion Based on our findings, maxillary lateral incisor agenesis plays a role in malocclusion development.
对于单侧或双侧先天性侧切牙缺失的患者，咬合重建和修复都很困难，并且常常导致错牙合畸形，需要进行矫治。本研究旨在评估单侧和双侧上颌侧切牙先天缺失情况，并研究接受正畸治疗的先天缺失患者的牙大小差异。材料与方法：我们评估了32副牙模，包括单侧或双侧上颌侧切牙缺失的男性17例和女性15例。测量近远中径，并对对照组和试验组的牙大小进行比较。对数据进行评估并记录结果。结果：与对照组相比，试验组上颌牙弓侧切牙在统计学上明显更小。男性和女性均如此（两者p值均为0.001）。在整个研究组中也观察到类似结果（p<0.0001）。结论：根据我们的研究结果，上颌侧切牙先天缺失在错牙合畸形的发生中起作用。
