Dens invaginatus is a developmental anomaly resulting from an invagination of the enamel or¡©gan. The incidence is highest with maxillary permanent lateral incisors. The reported occurrence ranges from 0.04 to 10%. This anomaly may involve the pulp and periapical tissues and cause pulpal inflammation, loss of vitality, apical and lateral periodontitis, periapical abscesses and cysts and stimulate internal resorption. Qehlers describes dens invaginatus as occurrence in three forms.
In treating type 3 invaginatus, treatment strategy can be determined by considering the com¡©plexity and accessibility of invagination. In this case, showing simple invagination, it could be treat¡©ed by simple endodontic treament confining to invagination without loss of vitality of tooth.
After treatment of the present case, the results were as follows:
1. In type 3 dens invagiantus, if the tooth is vital and there is no evidence of communicating be¡©
tween invagination and pulp, we can save the vitality of the tooth and resolve the lesion by
endodontic treament confining to the invagination.
2. In the invagination with opened apex, the closure of apex can be induced by apexification pro¡©cedure doing this, we can avoid the neccessity of surgical intervention.
