Postnucleation orbital implants.

A follow-up study of a group of 40 patients after the enucleation completed by the intra-orbital acrylic spherical magnetic implant (Roper-Hall style) is presented. The mean postoperative observation time is 3.3 years. Late complications were present in two patients: the extrusion of the implant in one of them was probably caused by his poor state due to chronic dialysis, while the traumatic luxation of the implant in the other was surgically repaired. Postoperative results in all other patients were satisfactory with the adequate orbital volume substitution and the ability of the prosthesis to twist and turn in any axis without fitting problems.

[Causes and treatment of hypersensitivity in tooth root].

The review article describes aetiology and treatment of dental root hypersensitivity. The three main theories of pain transduction from the exposed dentin surface to pain receptors in dental pulp are described. In addition, therapeutic compounds used to stimulate reparatory dentin formation and mineralization of peritubular dentin are described as well. The application of resins and adhesives on exposed dentin root surfaces is advocated in cases of chronic hypersensitivity. Finally, the authors emphasize the need for correct oral hygiene and early orthodontic treatment, if indicated, to prevent gingival recession and hypersensitivity of exposed root surfaces.
