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.

Save A Few Hours, Be More Productive

It seems like there are never enough days in the week, let alone hours in the day. Between work, children, and related responsibilities, a day can be over before you know it. You may have gotten everything done, but now there is no time left for you to concentrate on what you really enjoy. 

Here are four ideas that can help to save a few hours each week which you can then devote towards things you would rather be doing: 

COOK AND FREEZE 

Depending on what you’re cooking, it does not take all that much additional time to make more than you would regularly need. Doing this will allow you to put some in the freezer for later use, thus saving you having to cook from scratch every day of the week. 

PRACTICE NEATNESS 

Hate cleaning? Most people do. You can save yourself time here through the simple task of putting things away after you are done with them. Don’t throw them on the floor, leave them on the counter, or fail to toss them in the garbage. You’ll just have to do this later…and for many objects at once. 

SHOPPING EFFICIENCY 

Always remember to have a shopping list with you so that you don’t waste time wandering around the store trying to remember what you need. Also, it helps to go to a big box store where you can buy several types of things at once, rather than going to separate retailers for each thing. 

PUT THAT PHONE DOWN 

You would probably be aghast if you knew how much time you wasted each week looking at your phone, social media, and other things on the internet that do not really help you in any way. Limit your phone and computer time to just an hour or so a day, if possible. 

 

What the Interest Rate Hike Means for Mortgage-Holders

On July 12, 2017, the Bank of Canada raised its key interest rate from 0.50% to 0.75%. Canada’s five biggest banks immediately followed suite, matching the 0.25% increase in their prime interest rates.

The move came as no surprise to economists, who have been predicting a rate increase for some time now in response to record-high levels of consumer spending, housing prices, and household debt in Canada. But for many ordinary Canadians, who haven’t seen rates go up since 2010, the hike is alarming.

Some of you will have already felt the effects of the change. Others are still wondering if (and how) it will impact their day-to-day lives. We’ve examined how the new interest rate will impact two key areas: mortgages and the value of the Canadian dollar, and individuals like you.

What Does the Interest Rate Do?

As Canada’s central bank, the Bank of Canada sets the overnight interest rate. This is the rate banks pay to make one-day loans to each other. When the overnight interest rate goes up, banks usually increase their prime interest rate as well – which is what happened this week.

A bank’s prime interest rate is the rate banks use to calculate a variety of loans, including variable-rate mortgages and lines of credit. The five biggest Canadian banks (TD Canada Trust, Bank of Montreal, Scotiabank, and CIBC) all had a rate of 2.70% before the change. In response to the Bank of Canada’s change, they bumped the rate up to 2.95%.

That means bank customers with loans based on the prime rate will see their interest payments go up immediately.

Value of the Canadian Dollar

After the announcement went public, the value of the loonie shot up from 77.40 to 78.70 cents on the American dollar. That’s the highest the dollar has been since August of 2016. Some economists, including Adam Button of Forexlive.com and Scotiabank strategist Eric Theoret, predict it could hit 80 cents this year.

The cause? Confidence, according to Theoret. Though markets saw the rate increase coming, people were surprised by the Bank of Canada governor’s confidence in the move. This, along with positive economic data, shows the Canadian economy doing well and recovering from the recent oil-slump.

Mortgages and Housing Market

As mentioned, people with variable-rate mortgages will see an immediate uptick in the amount of interest they pay to lenders. The change could impact those with fixed-rate mortgages as well, as they could see higher rates when it comes time to renew.

For some, the change will be difficult to cope with. 0.25% is no small increase for those who are already struggling to pay their mortgages. It will be especially difficult for would-be house flippers who purchased a second or third home at the height of the housing boom in hope of a quick turn-around, seeing as the housing market has cooled since the spring.

But that’s not the only way the interest rate hike could impact housing. The other effect is harder to predict, but sure to be felt: a shift in consumer sentiment.

Preet Banerjee, the author of Stop Over-Thinking Your Money!, predicts the rate hike will change how Canadian consumers think about spending and borrowing.

“Because interest rates have fallen, and because borrowing money has become normalized, this could represent a real problem for them because they’ve gotten used to living month-to-month, paycheque-to-paycheque as a lot of people do, with very low costs of interest,” says Banerjee.

Right now, an alarming number of Canadians are comfortable carrying high debt loads and saving little to no money each month. Banerjee argues the interest rate hike could serve as a wake-up call.

This could only accelerate the recent dip in house prices, as consumers take a step back and wait for the right time to jump into the market. With real estate and financial services making up 20% of the Canadian economy, even small shifts in the market could have drastic effects on our economy overall.

Are Drive-Ins a Wise Investment?

Drive-ins were incredibly prolific in the 1950s. The combination of readily available and affordable cars, and teenagers looking to get away from their parents led to these outdoor cinemas enjoying considerable popularity.

However, the drive-in’s heyday started to decline in the ’70s and by the mid-80s, they were closing in droves. Home video caused many people to stay home, but one of the major considerations was the value of the land. As many towns expanded outwards, the drive-ins were no longer located far away. That increased the value of those particular plots, which were soon worth far when converted into shopping centers.

Drive-ins will never experience that kind of popularity again, but they have been getting more press lately, thanks to nostalgia and the fact that it is easier and cheaper to take a family to a drive-in than a multiplex.

As of this year, there are only 338 drive-ins left in the United States. A few decades back, it was not so unusual to have more than one in a single town; now you can drive through large sections of the country and not find a single one. In addition to fighting against the many forms of entertainment readily available, a good number could not afford the recent switch to digital projection and closed.

So, is a drive-in a good business investment? There are a few left that enjoy steady, large crowds, but generally, there are a lot safer ways for you to invest your money. If you do decide to open one, choose an area that is well away from expanding populations centers, but not so far away that people do not want to make the drive. Families tend to make up the lion’s share of patrons these days, so exhibitors tend to focus on booking movies that attract this demographic.

More Developments for Sears Canada

In the week since my previous post on Sears Canada, more news has come to light. While the majority shareholders in the company mull over their options, word has surfaced that the company’s pension fund may become a victim of the court-ordered restructuring.

The company announced that retirement benefits have been suspended for their employees. In addition to the loss of finances, the discontinuation of regular pension fund payout levels would likely also mean the termination of retiree health and life insurance benefits. With the pension plan currently underfunded, there is a very real chance this could occur. And you thought the loss of 59 locations, many jobs, and no termination packages was as bad as this could get?

There is something particularly despicable about robbing people of their pension benefits. The lure of a pension and financial freedom in your golden years causes many people to stay with a firm longer (sometimes much longer) than they would otherwise. That sort of employee loyalty is gained under false pretenses when you fail to protect their pensions in times of company financial strife. Sears’ problems are not the fault of their employees, but of systematic mismanagement in the C-suite. Will those men and women suffer in the same way? Probably not.

The law does not help the retirees’ case. They are considered to be the equivalent of unsecured creditors and that means their claims rank after those of banks and other secured creditors. Likely that means while they will get something, it will fall far short of the benefits they expected to receive until the end of their lives.

Such news is especially unfortunate for people this age because many are no longer in sufficient health to get a new job. This can lead to depression and anxiety woes, on top of the money concerns involved.
