How to become a dentist
Dr. Smile 30 December, 2007
(9) Comment There are different routes to becoming a dentist depending on which the country one lives. In some countries, high school graduates enroll in dental school. Some countries train medical school graduates to specialize in dentistry.
In the United States, dental schools choose top graduates of 4-year colleges for admission to dental school. These college students may choose any major course of study such as mathematics, chemistry, English, Music, or Art History. However, they must take a series of courses or prerequisites to prepare for dental school.
Most prerequisites are science courses, including one year of biology, two years of chemistry, and a year of physics. These courses enable the prospective dental student to understand applied science courses they will encounter in dental school such as pharmacology, anatomy, physiology, and dental materials. Communication is a very important skill for dentists; many dental schools ask that their applicants take at least one semester of a writing intensive humanities or social science course.

Lawyer Sues Insurance for failure to pay for White Fillings
Dr. Smile 30 December, 2007
(14) Comment A New Jersey lawyer who won a $45 million class action settlement last year from Horizon Blue Cross is suing the carrier in small claims court for not paying his $462 dental bill.
And the carrier, saying it fears the suit may be a prelude to another class action, has hired McCarter & English, the state’s largest firm, to make a federal case out of it.
A dentist charged Eric Katz $600 to fill a decayed tooth with composition bonding, but Horizon Blue Cross told him his coverage under his ex-wife’s family policy permitted reimbursement for an inexpensive silver filling only. The carrier pegged the benefit at $138, leaving the rest of the bill to Katz.
Katz appealed to the carrier, armed with a statement from dentist Fred Teschemacher that bonding was required because Katz’s teeth were “severely eroded.”

Proper Care Needed For Safety Of Mouthguards
Dr. Smile 18 December, 2007
(5) Comment Fractured teeth, neck injuries and abrasions in the mouth, also known as sports-related dental injuries, are ever present among athletes. According to the U.S. Centers for Disease Control, sports-related dental injuries account for more than 600,000 emergency room visits each year.
One may assume that mouthguards should serve as a preventive measure. In some 200,000 cases annually, mouthguards have been known to avert oral injuries and cut the risk of concussion by 50 percent. However, while a mouthguard may be popular for its ability to prevent the injuries that may temporarily and sometimes permanently disfigure a person’s appearance, what many may not be aware of is the importance of proper maintenance, cleanliness and care to prevent disease transmission and infection.
According to a study that appeared in General Dentistry, the AGD’s clinical, peer-reviewed journal, mouthguards harbor large numbers of bacteria, yeasts and molds that can possibly lead to life and/or health-threatening infectious/inflammatory diseases.

Cavities - Nature Or Nurture? $1 Million Grant To Pitt Dental School To Study Causes
Dr. Smile 18 December, 2007
(5) Comment Dental caries, also known as tooth decay or cavities, remains the most common chronic affliction of childhood, five times more common than asthma and seven times more common than environmental allergies. Four out of ten children have caries when they enter kindergarten. To identify the genetic and environmental risk factors that cause dental caries, the National Institutes of Health (NIH) has awarded a $1 million grant to the University of Pittsburgh School of Dental Medicine researcher Mary L. Marazita, Ph.D., director of the Center for Craniofacial and Dental Research, associate dean for research and professor and chair of oral biology. Dr. Marazita and colleagues will study the interaction between genes and environmental factors that lead to tooth decay. The results of these studies will allow a better understanding of the disease, which in turn will lead to earlier identification of children at risk and improved and targeted interventions.

gumEase- Drug Free Anesthesia
Dr. Smile 18 December, 2007
(7) Comment I have not tried this but it does look interesting. Go check out the gumEase web site for more information and watch the video.
Dental pain relief in seconds without drugs? The FDA says yes, recently certifying the first cryoanesthetic dental mouthpiece for the US OTC market. Used standalone or in conjunction with conventional anesthesia, gumEase provides pain relief without the side effects or complications of drugs. It’s a tempting solution for clinicians plagued with patient needle phobia, sharps and the complex issues of hypodermic delivery.
The easy-to-use, disposable device is a breakthrough in pain management - as effective as it is inexpensive. Inserted easily into the upper and lower sulci, the latex-free device delivers a soothing, cool temperature to the maxillofacial nerves, quickly diminishing pain across a wide area of the mouth. In patient tests the new gumEase diminished pain by 90% in 2 to 3 minutes for the average participant. Patients can apply them post-operatively as needed, and reuse without side effects by storing in a household freezer.

New CT Scanner
Dr. Smile 7 December, 2007
(4) Comment 
From the BBC News web site. Go check out the video
A new scanner has been unveiled which can produce 3D body images of unprecedented clarity while reducing radiation by as much as 80%.
The new 256-slice CT machine takes large numbers of X-ray pictures, and combines them using computer technology to produce the final detailed images.
It also generates images in a fraction of the time of other scanners: a full body scan takes less than a minute.
The Philips machine was unveiled at the Radiological Society of North America.
Because the images are 3D they can be rotated and viewed from different directions - giving doctors the greatest possible help in looking for signs of abnormalities or disease.
All images also can be accessed on any computer in a hospital or by colleagues and researchers remotely, to make it easier for the whole team to share information.

Humanoid robot teaches dentists to feel people’s pain
Dr. Smile 7 December, 2007
(2) Comment 
A group of robot and computer makers presented the high-tech dental patient in Tokyo at the 2007 International Robot Exhibition, a four-day technology showcase that opened Wednesday.
The medical simulation robot, named “Simroid,” is designed to be used for clinical training at dental schools, said Tatsuo Matsuzaki, an official at robot maker Kokoro Company Ltd., which developed the body and control system.
The 160-centimeter (five-foot-three) robot can say “it hurts” and frown when it feels uncomfortable from the dental drill.
“Because it’s so real, dental trainees can see patients’ feelings and will be able to develop good skills as they treat it, not as an object, but as a human being,” Matsuzaki said.

Dr. Smile 7 December, 2007
(4) Comment 
One of the larger booths at the GNYDM was from Ewoo Technology. They were displaying a number of imagining products including the Picasso Trio which is a CBCT, Panoramic, Cephlametric unit. You can get the unit without the Cephlametric. The images looked good and they were offering $20K discount with the trade in of your old Panorex machine. The EzImplant 3D software looked easy to use and the images were very good.
Check out more and the videos on the EWoo Technology website.

Root Amputation
Dr. Smile 5 December, 2007
(4) Comment
This tooth had been retreated once, and was failing to heal. Over time, an increase in the radio lucent lesion around the MB root was detected. The patient was then presented the options:
1. Root canal surgery to treat the MB root
2. Extraction & tooth replacement
Since the crown was in good shape, the patient wanted to try and save the tooth. The patient was informed that we would surgically expose the tooth, evaluated the root end. If no fractures are found, then we would recontour the root end (apical resection) and then place a reverse filling (retrofilling) in the end of the root. Patient was also informed if a crack is found down the length of the root, we’ll have to review other options.

Ultrasonic Irrigation
Dr. Smile 5 December, 2007
(3) Comment During endodontic treatment, our goal is to remove all pulpal tissue and micro-organisms, by-products from within the root canal system. We know that the root canal system is not only made up of the main canal, but may have isthmuses, fins, webs, anastomoses & other irregularities. These variations in the canal shape are impossible to cleanse mechanically. We must rely on our irrigant to reach the places that our files cannot reach. Opening the canals to a large enough size for the irrigant to reach the apex is an important step. I also like to use what I call “ultrasonic stirring”. I use an ultrasonic instrument to “stir” or “vibrate” the irrigant as it sits in the canal. Below is a little video clip showing how I do this.
