摘要
目的:研究朝鲜族恒牙外层解剖形态。方法:将在离体牙用电子数显卡尺测量牙外层,牙体全长、冠长、根长、冠宽、颈宽、冠厚、颈厚等按王惠芸测量标准做统计学方法分析。结果:朝鲜族上颌前牙宽度小于王惠芸资料,朝鲜族恒牙全长、冠长短于王惠芸资料,相反朝鲜族上颌牙根长度长于王惠芸资料。结论:为朝鲜族牙齿的美容、修复临床工作提供科学参考数据。
Objective:To study the anatomic morphology of permanent tooth external layer of Korean-nationality. Methods; The dental external layer of extracorporeal tooth were measured by electronic data-displaying calipers, such as body of tooth, span, length of dental corona, length of radix dentis, width of depth corona, width of dental neck, deep of dental corona and depth of dental neck. Statistical analysis was performed according to the measure of Wang Hui-Yun. Results: The width of duntal corona of upper maxillary incisor of Korean-nationality was shorter than reported by Wang Hui-Yun, Span and length of dental corona of permanent tooth were shorter than those of Wang Hui-Yun reported,but length of upper tooth root was longer than that of Wang Hui-Yun reported. Conclusion:The reference data is usful in extraction of permanent tooth of Korean-nationality and in aesthetic and rehab and clinic practice.
