Follow on Google News | Management of Gingival Tissue - Gingival Troughing using Diode LaserGingival troughing is the preparation of gingival tissue prior to taking impressions of teeth that have been prepared to receive a dental prosthesis.
By: Pioon laser technology co., ltd Treatment modalities- Techniques such as mechanical and chemical methods have been followed for gingival retraction. Retraction cords and pastes have been available for many years to help dilate the sulcus, thus exposing the finish line for an optimal impression. These methods, are technique sensitive. With hemorrhagic tissue, removal of the retraction cord or paste may reinitiate bleeding, preventing the impression material from fully capturing the preparation margins. This becomes more problematic as the preparation margin is placed deeper in the sulcus (sub-gingival) Almut Marsch in 2013 used wavelength 980nm, Dr. Kurtzman in 2017 used 810nm and NH Kamar Affendi et al in 2020 used dual wavelengths (810 nm and 980 nm) for gingival troughing and suggested that the use of diode lasers facilitates soft tissue management during impression making and serves as a valuable tool during the fabrication of accurate fixed prostheses. Rationale behind Use of Lasers- Laser offers certain advantages such as lesser operating times and lesser collateral heat generation, with good hemostasis and patient comfort. Use of diode lasers for retraction purposes has shown less recession around natural teeth as compared to retraction cord with laser. Studies have also shown bacterial reduction at treatment site and improvement in gingival marginal health. Conclusion – Taking into consideration the excellent clinical outcome, the diode lasers can be considered as a better and acceptable alternative for gingival troughing. Reference – Almut Marsch.
