Guided endodontics for the treatment and vital pulp concervation of type Ⅲ Dens Invaginatus in an immature maxillary lateral incisor with periapical periodontitis / 实用口腔医学杂志

ABSTRACT

A young maxillary lateral incisor of Oehlers type Ⅲ Dens invaginatus with peri-invagination periodontitis was reconstructed by CBCT,with the help of guided endodontics,the pathway to invagination was successfully established.The invaginated pseudo-root canal was treated with Vitapex mediation while preserving the pulp.After 6-month follow-up,the tooth was clinically asymptomatic.Radiological ex-amination indicated complete healing of the peri-invagination lesion with narrowed open apex,and the thickened root canal wall.
