ABSTRACT
Objective To investigate the relationship between the root diameter and the diameter of the root canal and the diameter of the root canal of the maxillary central incisors of Han nationality.Methods November 2014 to 2015 during November,select the database in a local three grade hospital in 420 cases of Han nationality in CBCT image data as the research object,according to the age will be all of the subjects were divided into six (8~12 years old,13 to 17,18 22,23 to 27,28 to 32,33 to 37 years old),70 cases in each group,men and women,15 cases in each group.Of all the research object of the maxillary central incisor root diameter and root pipe diameter were measured,take the cemento enamel junction from the apical 3/4,analysis of maxillary central incisor root diameter and root tube diameter and age,men and women of the maxillary central incisor root diameter.Results The men and women of the maxillary central incisor root diameter compared with significant difference (P<0.05);male and female maxillary central incisor root diameter compared with significant difference (P<0.05);male and female maxillary incisor root diameter and root diameter ratio compared with the difference significant (P<0.05);different genders maxillary central incisor root diameter and root diameter ratio and age has certain correlation (R2=0.623,P<0.05).Conclusion The root diameter and the diameter of root canal of maxillary central incisors of Han nationality were correlated with the age,and the trend of male root canal diameter was higher than that of female.
