Endodontic treatment of an invaginated maxillary lateral incisor with a periradicular lesion and a healthy pulp.

AIM To report the healing of a periradicular lesion following nonsurgical root canal treatment of a dental invagination. SUMMARY A case of dens invaginatus type 3 with a periradicular lesion and a healthy pulp is reported. Nonsurgical root canal treatment of the invagination was performed successfully and resolved an associated periradicular lesion. Despite the complex anatomy and a diagnosis of apical periodontitis, pulp health was retained after endodontic treatment of the invaginated canal. Clinical considerations and treatment are discussed and reported. KEY LEARNING POINTS Dens invaginatus can present in a variety of forms, knowledge of which can usefully inform endodontic diagnosis and treatment. In certain cases, success can be achieved by treating the invagination alone. Pulp health may be preserved during and after treatment of an infected invagination.
