中文摘要:
      目的:调查江苏汉族人群上颌前牙牙周生物型的分布,以及牙冠宽长比(crownwidth/crown length,CW/CL)、龈乳头高度(palilla height,PH)和附着龈宽度(attached gingival width,AGW),为前牙美学区的口腔治疗提供解剖学参考。方法:招募江苏地区牙周健康的汉族志愿者108例(男52例,女56例),根据牙周透射探针法,将上中切牙牙龈分成厚、薄两型,再结合牙齿形态和龈线起伏,细分为薄扇型、厚扇型或厚平型3种牙周生物型。同时,测量CW/CL、PH和AGW,分析上述解剖学指标在不同牙周生物型、性别、年龄和牙位间的分布差异。结果:江苏汉族人群中,薄扇型占30%,厚扇型占19%,厚平型占51%,平均CW/CL 0.84±0.09,平均PH(3.93±0.80)mm,平均AGW(4.80±1.39)mm。厚平型CW/CL和AGW明显大于其余两型(P<0.05),PH明显小于其余两型(P<0.05)。结论:江苏汉族人群牙周生物型以厚平型为主,口腔治疗的美学风险相对较小,不同牙周生物型的CW/CL、PH和AGW存在差异。
英文摘要:
      Objective:To expiore the distribution of periodontal biotypes and relate anatomic parameters in maxillary anterior teeth,including crown width/crown length ratio(CW/CL),gingival papilla height(PH)and attached gingival width(AGW),in Han population in Jiangsu Province.Methods:A total of 108 periodontal heathy Han volunteers (52 males and 56 femals)in Jiangsu Province were included.Three kinds of periodontal biotypes,thin-scalloped,thick-scalloped and thick-at,were assessed according to transparency of periodontal probe through gingival margin in maxillary central incisor and some related anatomic characteristics.In addition,CW/CL,PHand AGW of maxillary anterior teeth were also analyzed.Results:In Han population in Jiangsu province,30%persons were thin-scalloped type,51% were thick-flat type,and only 19% were thick-scalloped type.Mean CW/CL in Han population was 0.84±0.09,mean AGW was(4.80±1.39)mm,and mean PH was(3.93±0.80)mm.CW/CL and AGW in thick-flat biotype were singnificantly higher than those in thick-scalloped and thin-scalloped(p<0.05) ,while PH in thick-flat biotype was singinficantly lower than that in the other two biotypes(p<0.05).Conclusion:The most popular periodontal biotype in Han population in Jiangsu Province is thick-flat biotype,which is the biotype with lower aesthetic risks.Differences in CW/CL,PH and AGW do exist in different periodontal biotypes.
