To describe the clinical management of an unusual dens invaginatus type 2.

A case of dens invaginatus in a maxillary lateral incisor with a periapical lesion is reported. The patient presented with pain and localized swelling. Despite the complex anatomy and diagnosis of dens invaginatus , non-surgical root canal treatment was performed successfully.

Key learning points.
• Dens invaginatus may be presented in many forms, and the aetiology of this phenomenon is not fully understood.
• Due to abnormal anatomical configuration, dens invaginatus presents technical difficulties in its clinical management.
• Non-surgical root canal treatment can be performed successfully.

This study was undertaken to determine the incidence of root fractures during post removal, as well as the methods used and the success rates achieved with various post removal devices and techniques.

This study indicates that, with good case selection, post removal is a predictable procedure. If appropriate techniques and devices are used for the particular type of post being removed, then root fracture is a rare occurrence.

This work was designed to investigate the potential cytotoxicity of two of the newer dental restorative materials, Spectrum® composite resin and Dyract® AP compomer.

These results indicate the restorative materials to be potentially toxic, particularly if the degree of light-cure is inadequate.

» A comparative study of root canal preparation using ProFile .04 and Lightspeed rotary Ni–Ti instruments
By JofER editor | Published 01/18/2002 | Endodontic Articles 1 | Unrated

J. Versümer, M. Hülsmann & F. Schäfers
Department of Operative Dentistry, University of Göttingen, Germany

The purpose of this study was to compare several parameters of root canal preparation using two different rotary nickel–titanium instruments: ProFile .04 (Dentsply/Maillefer, Ballaigues, Switzerland) and Lightspeed (Lightspeed Technology Inc., San Antonio, TX, USA).

Both systems under investigation respected original root canal curvature and were safe to use. Both systems can be recommended for clinical use.
