The Slow Evolution of the High-Speed Dental Handpiece

The invention of the electric motor-driven dental handpiece was pivotal to the development of modern dentistry. High-speed handpieces enable modern dental professionals to perform intricate surgical work efficiently and at minimal pain or discomfort to the patient. But the handpiece (also known as the dental drill) has a long and fascinating history that predates the notion of anything ‘high-speed.’

Dentistry itself is known as one of the world’s oldest medical professions, dating back to 7,000 BC. Anthropologists in Pakistan have identified human remains from that era containing drilled molars; a drilled molar has also found in a Neolithic graveyard in Denmark dating to 3000 BC. In other words, there is evidence of some form of dental handpiece existing almost ten thousand years ago.

However, these early handpieces might not have looked anything like the dentist’s drill we recognize today. Before industrialization, dental cavities were prepared very slowly, with dentists twirling long flint-tipped burs manually or with a bow-like contraption. Many of us would cringe at the thought.

Despite its lack of sophistication, this was the reality of the dental drill for hundreds or even thousands of years; it wasn’t until the mid-18th century that development of the modern handpiece began in earnest.

French physician Pierre Fauchard is credited with re-discovering dental drill technology, describing its use for root canal procedures in a 1746 publication. This version of the dental drill consisted of a long metal rod and a bow used to power it. Not long after, in 1778, a hand-crank-powered drill was introduced, followed by device powered by the motion of a foot pedal. The foot-powered mechanical handpiece was significant because it freed both a dentist’s hands for surgical work.

Handpiece innovation really kicked into high gear in the late 19th century, when the first electrically-powered drills came on the scene. By 1938, dentists used motorized belt-driven drills that spun at speeds of 2000 rpm; by 1950, 6500 rpm had become the standard. Finally, in 1959, dentist John Borden filed a patent for a air turbine handpiece with bur speeds of 250,000 rpm that revolutionized the practice of dentistry.

Borden’s patent is remarkably close to the high-speed handpieces we still see in dental practices around the world. Subsequent innovations have focused on making the handpiece smaller, more durable and more comfortable for patients and practitioners alike. Today, the best quality high-speed handpiece parts are made from lightweight, durable materials like aluminum and platinum.

Why This Clean and Safe Silicone Bong Mouthpiece Is Awesome and Important

Cannabis is better when people consume it together. It has always been that way. Social consumption has been a central part of its usage thousands of years, all the way back to its use as a medicinal and spiritual tool by our prehistoric ancestors.

Many people still use cannabis for medical and spiritual purposes today; for others, it’s a way to bond and commiserate.

I never really appreciated this until I basically stopped drinking. I say ‘basically’ because I still drink very occasionally under limited circumstances, but for the most part I avoid it, knowing that I can no longer do so responsibly. Point is, cannabis achieves much the same purpose as alcohol in social situations, but without the looming Damocles of dependence.

But there is dimension to social smoking that doesn’t really exist with social drinking: sharing. Rarely do friends and acquaintances share a beer or a glass of wine outside the realm of drinking games, but puff-puff-pass is an intrinsic and valuable component of social smoking that adds another layer of togetherness.

That’s why preach the virtues of this clean and safe silicone bong mouthpiece called the Mouthpeace, the premise of which is to allow someone to participate in a smoking session without sharing the other participants’ germs.

Moose Labs, the company behind the Mouthpeace (and other bong pieces for cannabis use), pushes the product in a tongue-in-cheek way. Sharing a joint with a stranger is like kissing a stranger! Always practice safe sesh. It’s true, but for some people, it’s also fairly serious business.

When I first encountered the Mouthpeace, my thoughts immediately jumped to an old friend of mine: a generous social smoker who delights in sharing and introducing people to weird strains. But also, someone who is frequently immune-compromised to the point that they cannot even take public transit without respiratory protection.

During those times, smoking becomes a solitary activity designed to combat the medication’s appetite-suppressant effects. Sharing a joint at that point is unthinkable; it’s just not worth the risk.

The Mouthpeace wasn’t around when we were close, or at least I didn’t know about it. But I often think of that old friend when I use it, and wonder if it could help them relax and unwind with their friends when times are tough.

We don’t talk anymore; things came between us. But I’ve gifted a Mouthpeace or two to our mutual friends, so maybe they’ll learn of it someday. Maybe it’ll help.

I hope plenty of other people will discover it and benefit the same way.

Chest Freezer vs. Upright Freezer: What’s Better for a Small Home?

Confession: I hate couponing. Much as I consider myself a frugal shopper, I have no patience for flyers, coupons or meal planning. I admire those of you who plan your weekly grocery shopping in advance based on whatever is on sale, but it’s just not for me.

My lazy approach to frugal groceries is this: if the stuff I want is on sale, I buy it. Lots of it. If it’s not, then I skip buying it. That’s it. No meal planning, no change to my usual routine.

So, how do I manage not to run out of the essentials? Easy: when something is cheap, I buy as much as I can and stash it into the freezer.

That way, even if I don’t catch a sale again for another two months, I’ll still have everything I need. I’ve gone weeks without buying the fruits or veggies I like because I’ve got them stockpiled.

Now that I’m in a slightly bigger place, I’m looking to upgrade to a separate standalone freezer. But I’m still working with limited room. That lead me to the question of whether to go with a small chest freezer or an upright one.

Is a small upright freezer perfect for small homes, or are you better to go with a chest freezer? Here are the benefits of each.

Chest Freezer

  • Sits flush against the wall
    Small chest freezers usually have ventilation is on the side of the appliance, which enables you to put the back a chest freezer flush against the wall. Like refrigerators, upright freezers usually require some clearance around the back. Depending on the layout of your home, a chest freezer could save some space.
  • Energy-efficiency
    Chest freezers open at the top instead of the front, meaning the door less likely to be left ajar by accident. The door is also better-insulated than what you’ll usually find on an upright freezer, which is a bonus.
  • More affordable
    Chest freezers tend to be a bit cheaper than upright models. They’re also easier to find second hand, if you’re into that.

Upright Freezer

  • Better visibility
    It’s much easier to find what you’re looking for in an upright freezer compared to a chest freezer. All your food is laid out in vertical shelving instead of piled on top.
  • More storage options
    In addition to the shelving inside an upright freezer, you can store smaller items in the door for easy access. Easy access means less rooting through the freezer while the cold seeps out.
  • Smaller footprint
    This is one of the biggest points in favour of an upright freezer, so long as you have the vertical space to accommodate one.

It’s the upright freezer that wins out for me, personally, and I can’t wait to get one home.

Top Things To Prioritize Before Purchasing New Supplements

Acquiring enough nutrients each day is essential for your well-being. Nutrients give you the vitality to finish every day tasks, assemble muscle, repair body tissue, counteract disease and keep up a solid weight.

Supplements must be completely processed to do their thing. In the event that your stomach’s corrosive levels are low since you’re focused on, you smoke, or you don’t eat well, you should flush those tabs down the loo – not great when multi month’s supply can cost as much as an exercise center enrollment.

5 Times LED Lights Became Unexpected and Awesome Works of Art

Through my work with green tech companies, I’ve become more enthusiastic about the potential of LED lighting than I ever thought I would. But I also tend to see only the utilitarian side of the technology: the efficiency, affordability and so on. For a change of pace, I decided to go on an exploration of the artistic side of LED lighting, and discovered there’s an entire genre of sculptures and installation harnessing LED lighting to create beautiful and provocative imagery.

Here are five of my favourite examples so far.

MONUMENT (2008)

Jenny Holzer is a sculptor who has been using LED lighting to project political messages since 1982. Her works combine text written by her and borrowed from other sources, including poetry, to form thought-original pieces.

One of her more recent works was MONUMENT in 2008: a futuristic-looking monolith that displays LED phrases from declassified US government documents surrounding the War on Terror. The result is something that looks like an awesome prop from a movie I wish existed.

LIGHTING GIANTS (2014)

One of the awesome things about LED lighting is their ability to reframe mundane objects into something that gives you pause. That’s definitely the case with this installation in Croatia, in which shipyard cranes were transformed into beautiful geometric sculptures using only the power of colourful lights. Watch the video to see them in action — it’s something like a stationary fireworks display.

SCATTERED LIGHT (2011)

An early adopter of LED lighting in art, Jim Campbell has created temporary and permanent installations all over the US. This particular piece, illuminated in Manhattan’s Madison Square Park, was part of his Exploded Views series – which were meant to reveal hidden images when viewed from afar. Inhabitat’s description of them as LED Magic-Eye pictures is a good way of explaining it. Up close, it looks like a waterfall of LED lights, but it transforms into something else entirely when you take a step back.

ARROW OF TIME (UNFINISHED LIFE) (2016)

Tatsuo Miyajima’s Arrow of Time installation at the Met immersed viewers in an eerie, blood-red world that is meant to make them, “experience the irreversibility of their lives.” In other words, awesome. The work’s 250 LEDs are programmed to count from one to nine repeatedly, then go dark, repeating the sequence to symbolize the unending cycle of birth and death.

PIXEL (2013)

Unlike the other pieces on this list, Pixel is something you can actually buy and take home with you. Like a super-powered LITE BRITE, uses a 32 x 32 LED display to create sprite art. You can customize it using Raspberry Pi, or display one of the many pre-programmed images (but who’d want to settle for that?)

Create Your Own LED Masterpiece

LED lights are awesome, and you can’t go wrong with the guys at Tradeforce for commercial LED applications. On the other hand, if you’re building a 20-foot sculpture designed to remind us of the frailty of life, I’m sure they’d be able to help you out there as well.
