Jason Pang: A Review of the Nd:YAG for Photobiomodulation and Practical Application of the Genova Handpiece in Dentistry
The use of low level laser therapy or more appropriately photobiomodulation (PBM) has been investigated for over 30 years. The effects include improved wound healing, reduction of inflammation and pain relief. Research into its benefit in veterinary and medical settings have been well documented using a range of laser wavelengths. Limiting factors to its more widespread use have been the long exposure time and operator variability.
The 1064 nm Nd:YAG laser penetrates deeply into cellular tissues and has been shown to be a suitable wavelength for biostimulation. The use of PBM in dentistry has been underutilised, and research into the use of Nd:YAG for PBM in dentistry has been limited. However, there have been cellular studies, clinical cases and case reports indicating that there is enormous potential for its use.
The Genova handpiece is unique in its design, with a collimated flat-top radiance profile. The uniform delivery of high peak power, low-level laser energy allows us to minimise exposure time and simplify delivery. The advantages of this handpiece compared to other available handpieces and defocused output will be explained.
A review of current research using Nd:YAG for PBM will be presented along with rationale for use of the Genova handpiece at this wavelength in dentistry. Dental uses for PBM include acute and chronic oral lesions, post-surgery/implant placement and extraction as well as restorative, orthodontic, endodontic and periodontal applications, and in combination with Er:YAG procedures such as NightLase.
