Why People Hate the Dentist

Numerous posts on the internet have attempted to shed light on the why people hate the dentist. Tom over at OralAnswers.com has a two part series on why people hate the dentists located at http://www.oralanswers.com/2011/09/why-people-hate-the-dentist/ and http://www.oralanswers.com/2011/09/why-people-hate-the-dentist-my-theory-part-ii/ Dr. Joe Bulger DDS in Canada changed the name of his blog to hatedentists.com and his written several posts on the topic of people who hate dentists located at http://www.hatedentists.com/1319/hate-dentist/ , http://www.hatedentists.com/1326/dentist-haters/ , and http://www.hatedentists.com/1363/top-10-reasons-people-hate-dentists/ SaneDentist.com has a post by Dr. Mujtaba Ali regarding 5 reasons why people hate the dentist located at http://www.sanedentist.com/here-are-5-reasons-why-we-hate-the-dentist-and-what-a-dentist-thinks-about-them.html Reading, over these posts and potential explanations for hate towards the dentist just doesn’t seem to do the hate justice and doesn’t touch on all the issues. So here are some reasons why I think people really hate dentists (subjective opinion): 1) Being motivated by money to the point of detrimental care to their patients Let’s face it, people go to work to make money so they can survive and look after their loved ones. However, dentistry is not a business and should be about making people motivated to practice healthy habits and not pushing unnecessary surgeries and care. This is touched on on the controversy page of this […]

How does Flouride really Protect Teeth from Cavities?

A recent study that appeared in the journal Langmuir looked into the role of fluoride and their protection on teeth. The researchers who published the journal article found the protective shield fluoride forms on teeth is up to 100 times thinner than what was previously thought. It is well known that fluoride is found in toothpaste, mouthwash, and public drinking water in many areas in the world. The use of fluoride of course is to help prevent tooth decay which causes cavities to form. Researchers found the fluorapatite layer created by fluoride on the hard white substance covering teeth’s surface called enamel is only 6 nanometers thick. This layer is very small and over 10 times thinner than what was indicated in any prior studies. Hence the researchers raise questions about how a layer so thin can protect teeth from decay. Hence it is possible that fluoride may have another unrecognized effect on tooth enamel. It is worthy for researchers to explore how fluoride protects teeth from cavities as there is some controversy surrounding the fluoridation of drinking water. Previously I have discussed how large amounts of fluoride consumed can lead to fluorosis in young children. Source: Frank Müller, Christian […]

Growing Teeth Formula

Researchers at the  Institute of Biotechnology of the University of Helsinki developed a computer model reproducing population-level variation in  teeth. This has implications for growing correctly shaped teeth. With more than 15 years of work, Jukka Jernvall and his team have compiled data on the evolutionary development of mammal teeth and the main aspects of a formula for making teeth emerging. According to a mathematical computer model, a rather simple basic formula seems to be behind the complex gene puzzle resulting in tooth formations. The jungle of gene networks has a ‘patterning kernel’ which regulates the variation of teeth among individuals. It is possible that human teeth from the incisors to the molar teeth may result from a single factor which regulates cell division. The researchers have investigated their model on seal teeth. The Ladoga ringed seal collection  at the University of Helsinki served as an ideal population sample  because dentitions are highly variable. Isaac Salazar-Ciudad and Jukka Jernvall.

Perfect Looking Teeth

A new measuring technique determines the effect of dental care products and helps  them so they polish the rough tooth surfaces until they are perfectly smooth, while preserving the tooth enamel. The tooth surface wears down and gets uneven – and the problem is that dental plaque adheres particularly well to a rough surface. Dentists therefore offer professional cleaning services, removing plaque and discoloration with abrasive prophylactic pastes. This renders the tooth surface beautifully smooth, making it difficult for bacteria to gain a foothold. Yet there is a risk that the polishing treatment will also grind away precious tooth enamel and dentin at the exposed necks of teeth. The manufacturers therefore have to find the happy medium when developing their prophylactic pastes: The pastes should be just abrasive enough to remove superficial discoloration and plaque, but preferably not wear down the tooth enamel. Until now, scientists lacked any realistic objective measuring techniques to assess tooth abrasion caused by chewing and by the effect of toothpastes. A leading manufacturer of dental hygiene products asked the Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, one of whose specialties is the analysis and visualization of surface roughness, to help them develop new […]

Swimming Causes More Dentist Trips?

With the recent Michael Phelps frenzy in the 2008 Summer Olympics a lot of people may have a renewed interest in the sport of swimming. I personally have been actively swimming regularily for the past few years. I recently went on to the American Dental Association (ADA’s website) and took a look at some of their dental minute videos. One such video discusses how swimming more than 6 hours a week can cause your teeth to become brown. Thus swimming chemicals can stain your teeth. This can be managed though with regular dental exams. To view the video by practicing dentist Dr. Maria Lopez Howell go to the following link http://www.ada.org/public/media/videos/minute/additional_swimmingpoolchemicals_broadband.wmv (you will have to download it)
