Abstract：AIM:To observe the root apical type and related factors in adults after apexification.METH-ODS:50 teeth with root apex dysgenesis and chronic apical periodontitis were treated by apexification with Metapex un-til apex closure.The root canals were then filled.Same teeth in another site of the same jaw served as the controls.Da-ta including age,development of root apex,time of chronic apical periodontitis and root apical type were analyzed by rank correlation.RESULTS:20% of root apex were FrankⅡand 70% were Frank Ⅲ in apexification group,which was different from that in the control group.Root apical type was positively correlated with the time of chronic apical periodontitis,but were negatively correlated with age and development of root apex.CONCLUSION:The root apex does not develop after apexification in adults,only apical barrier can be formed.
