#32 Loupes

Loupes

Today in sim lab, our class spent the entire four hours practicing some Class 1 preparations/restorations (recall: Class 1 are preparations done on carious lesions found in occlusal pits or fissures). We specifically prepped and restored teeth #3, #4, #13, #14, #19, #21, #29, and #31. Given what we did today, I think it's an appropriate time to talk about the pros and cons of loupes.

The pair I use (and cherish) are 3.5x TTL (through-the-lens) EF (extended field) DFV (Design for Vision; company) with Buddy Holly (thick) frames. I also use them with the light that is offered by DFV (can't remember the name of it off the top). Prior to this, I used a pair of 2.5x no-name, cheap clip-ons as a way to get used to using loupes in the beginning. As mentioned above, I absolutely love them. They have a great field; you can see an entire arch with the extended field. This is a feature which is pricey, but absolutely worth it. It gives you both the flexibility of great magnification for a single tooth, while still being able to see the 'big picture'.

The learning curve for me was pretty low. It took me about 3 long (think 2+ hours) sessions of using them before I got to the point where it feels second nature. They allow you to see your prep very clearly; with the light, you do not get any shadowing effects occuring. Plus, the light follows your vision, so no constant adjustment is necessary. Also, they are FANTASTIC on your posture. I am able to perform my work from the ideal, ergonomic position, and have next-to-none muscle/back/neck fatigue after multiple hours of work. This will be invaluable to me during my future years.

The cons: expensive. Even with a student discount, you are going to have to shell out close to a couple grand for them. You do have the option of returning them at full cost prior to 45 days, but you should be comfortable with what you are getting into. As well, you do become dependent on them; looking at my typodont without them on, I question if I could do a respectable preparation without them. This point is slightly moot; it just means that I have to be careful with my loupes and be sure not to break them or lose them. This is unlikely as they have a strap attached to the back of the glasses, and I guard/treat them as if my life depends on it.

To summarize, buying a pair of loupes is a personal preference. However, I implore you to take a look at the pair I use. I am very, very pleased with the decision I made, and look forward to using them for many years to come.
