Effect of micro osteo-perforations (MOP) on the rate of tooth movement and levels of interleukin- 1β - a split mouth study.

Introduction: Various procedures are available today to enhance tooth movement, with relative success rates, one among them being micro osteo-perforation (MOP). Our aim is to assess the rate of tooth movement and interleukin-1β levels in gingival crevicular fluid levels (GCF) after MOPs.

Methods: A group of 22 patients were selected, who required first premolars extraction and were designated for the split mouth study with equal allocation.

Evaluation of Mechanical and Physical Properties of Clinically Used and Recycled Superelastic NiTi Wires.

Introduction: The initial leveling and aligning phase has been simplified with the introduction of superelastic nickel-titanium archwires. The relatively high cost of these wires has prompted some of the clinicians to reuse them after sterilization. The quantitative changes in the surface properties of superelastic 'NiTi' wires after clinical application and recycling by autoclave method have not been established in earlier studies.
