Non Extraction treatment of Mandibular crowding by Distraction, Unique approach
AJODO Volume 135, Issue 4, April 2009, Pages 530-535




In this article, we describe a midsymphyseal distraction osteogenesis treatment with a novel dentally supported appliance. This approach differs from that used in previous reports because the incisors were allowed to move during the distraction procedure. This report shows that midsymphyseal distraction osteogenesis can be used to expand both arches to produce a wider smile. Borderline cases can be treated with this technique without the compromising effects commonly observed with conventional therapy.

Enamel Strength Affected By Dental Home Bleaching

New research shows that human teeth lost some enamel hardness after the application of several different products used in the home to whiten teeth. The study suggests that future generations of such products might be reformulated in an effort to reduce these side effects.

The researchers noted that teeth typically can restore their previous hardness after losing small amounts of enamel calcification. But this is the first study to show at a nanometer scale - measuring in billionths of a meter - how human teeth are affected by the popular home whiteners. MORE HERE

The dental gold rush is on

The market in dental gold hasn't reached bonanza heights, but people squeezed by the recession are making a few extra bucks by selling old gold caps, bridgework and other bits of what is known in the trade as "dental scrap." Depending on weight and other factors, a gold tooth can go for $50.

Outside the Continental Coin and Jewelry Co. in Van Nuys, an electronic marquee draws prospective sellers by flashing images of money-making opportunities -- a dazzling gold ring here, a bright gold dental crown there.

"If it's gold, we're buying it," said marketing director Jeff Ringer. "You'd be amazed at what people bring in." MORE HERE

Dentists In The Dark About Teeth Grinding (Bruxism)

Teeth grinding and clenching, more commonly referred to as `bruxism` is an involuntary action, usually occurring at night and endured by millions of people in the UK. Although there are many possible causes, the main culprit appears to be stress. The consequences for the chronic bruxer can be severe. Not only can it result in disturbed sleep for themselves, but their partner can lose sleep from the constant grinding and gnashing noises. In the morning, the sufferer may wake up with several symptoms, including a throbbing headache and neck, shoulder and jaw pain. In extreme cases, they may also find that their fillings have become loose or fallen out altogether and teeth are fractured and worn down.

NoBrux, a UK company that specializes in the supply of US made dental guards to dentists and sufferers have carried out a survey on their website [http://www.nobrux.co.uk/] Respondents were asked "Does your dentist routinely ask whether you grind your teeth and discusses treatment options with you?" Around 80% of respondents said "no". MORE HERE

Frustrations of an unknown Dentist

This is an email from a Dentist, it could be anyone among you, change your life today, join our Molar Endodontics one week course to transform your life and never be frustrated again.

"I Am frustrated using all the systems like MM SONIC , PROTAPER ,X MART(was promoted to me to ensure less file fracture but in vain) and ultimately PROPEX II apex locator which falls at least 5-7mm short of apex.

I am a UG, completed in 1996 and practicing in Chennai. I get frustrated to get appointment from the Endodontist and match the same time for the patients to come. If I do RCT it takes almost an hour and in my practice that is too much time. I have used all Endo systems and costly equipments still I am uncomfortable. Recently I bought Propex II, X Smart but they have been of no help at all."
