Tool of the Trade Review: Hoya Diode Soft Tissue Laser


by Dr Laurie Kobler, Integrity Dental, Dural, NSW

About six years ago, I bought a combination hard and soft tissue Erbium laser. I then realised there were times when having a dedicated soft tissue laser was going to be significantly beneficial and worth the investment. So I also purchased the Hoya diode laser.

What’s good about it

It’s very simple to use. You initiate the fibre—which takes about two seconds—and then it’s ready to cut soft tissue with negligible bleeding. It also cuts with such minimal discomfort, I’m able to use it without local anaesthetic for minor soft tissues procedures.

The process of initiating is very simple. Once the laser is turned on, the tip is run across a piece of carbon paper. The carbon chars onto the tip which helps generate heat. An uninitiated tip won’t be able to cut but the laser energy will still kill bacteria.

I mostly use it for restorative procedures but it is also quite useful as a root canal disinfecting tool. The fibre is about 600 microns in diameter so it can pass quite a long way into a canal. The uninitiated laser energy kills bacteria and disinfects the prepared canal very effectively.

It can also be used to disinfect periodontal pockets in the initiated and uninitiated phase. The initiated fibre will cut the inside of the soft tissue in the pocket and the uninitiated fibre disinfects the pocket.

What’s not so good

The glass fibre that carries the laser from the unit to the handpiece needs to be constantly trimmed. Every time it is used, it must be trimmed again.

When using the unit, everyone in the room must wear safety glasses to protect their eyes from damage. I use magnification for virtually every procedure so I had to construct a system whereby I can use magnification while wearing the safety glasses. It took a while to sort out but it works fine.
