Effect of Vitapex apexification in inducing the root apex development of young permanent teeth

Objective To study the effect of the Vitapex apexification in inducing the root apex development of young permanent teeth.Methods A total of 300 drops of young permanent teeth were treated in the Stomotology Hospital of Shenyang from 1999 to 2004 with Vitapex apexification.The teeth included 40 anterior teeth,220 premolars and 40 molars.The reasons for pulp necrosis included 29 injury teeth,51 caries teeth and 220 abnomal apex fracture.Results Totally 290 teeth were treated successfully,and 10 failed,the achievement ratio being 96.6%;in the 40 anterior teeth,38 were treated successfully(95.0%);in the 220 premolars,216 were treated successfully(98.2%);in the 40 molars,36 were treated successfully(90.0%);of the 29 injury teeth,success in 27 teeth(93.1%);of the 51 caries teeth,success in 48 teeth(94.1%);of the 220 abnomal apex fractured teeth,success in 215 teeth(97.7%).The time of apex development was from 6 to 24 month.Conclusion The Vitapex apexification is an reliable and available approach in inducing the root apex development of young permanent teeth.
