Dental tartar apparently first made an appearance about 400,000 years ago.

Tel Aviv University researchers, along with scholars from Spain, the United Kingdom and Australia, found respiratory irritants in the dental calculus of 400,000-year-old teeth at Qesem Cave near Tel Aviv. This also happens to be a site of many major discoveries from the late Lower Paleolithic period.

The respiratory irritants were caused by smoke inhalation from indoor fires used for roasting meat.

The research was published in Quaternary International, led by Prof. Karen Hardy of ICREA at the Universitat Autònoma, Barcelona, Spain, together with Prof. Ran Barkai and Prof. Avi Gopher of TAU’s Department of Archaeology and Ancient Near Eastern Civilizations, in collaboration with Dr. Rachel Sarig of TAU’s School of Dental Medicine, Dr. Stephen Buckley of the University of York, Anita Radini of the University of York and the University of Leicester, U.K., and Prof. Les Copeland of the University of Sydney, Australia.

The age of the teeth, combined with the age of the plaque, did not give the researchers much hope of ascertaining a lot of information. But they were able to discover many materials entrapped within the calculus. The cave where the tooth was discovered had been sealed for about 200,000 years, so it was preserved well.

The findings showed that the teeth included remnants from charcoal from indoor fires, evidence that plant-based dietary components were consumed and there were fibers that could have been used to clean teeth.

Never before this study had there been evidence of people roasting meat indoors so early in history. The ensuing pollution was the first of its kind. There was also evidence of essential fatty acids in the their teeth, such as nuts or seeds.

This information filled in many gaps about how people lived in that time of history.

In a recent study published ahead of print in the Journal of Periodontology, Brazilian researchers have found that consumption of alcoholic beverages can have adverse effects on the health of a person’s gums, aggravating existing cases of severe periodontal disease or increasing periodontal disease risk factors. Moreover, previous research indicates that poor oral hygiene is a common trait in alcohol users, thus increasing drinkers’ susceptibility for developing periodontal disease. “Although the topic of alcohol use and its effect on periodontal health requires further research, this report offers valuable insight on why our patients should care for their gums and teeth, especially if they enjoy the occasional drink,” remarked Joan Otomo-Corgel, DDS, MPH, President of the American Academy of Periodontology. In the study entitled, “Alcohol Consumption and Periodontitis: Quantification of Periodontal Pathogens and Cytokines,” researchers assessed a sample of 542 regular alcohol users, occasional drinkers, and non-drinkers both with and without periodontitis. Some key findings noted in the study include:

• The severity of a regular alcohol user’s existing periodontitis correlated incrementally with the frequency of his or her alcohol consumption. As a result, these individuals were found to require additional periodontal treatment.
• Drinkers without periodontitis saw an increased incidence of gums that bled with gentle manipulation.
• More frequently than the non-drinkers in the study, drinkers who did not have periodontitis presented clinical attachment levels of four millimeters or greater.
• Drinkers without periodontitis exhibited a higher presence of plaque than their non-drinking counterparts. Study researchers noted that alcohol’s drying effect on the mouth may contribute to the formation of plaque that can trigger an inflammatory response in the gums.

“Alcohol slows the production of saliva, which helps neutralize the acids produced by plaque, and an accumulation of these acids can lead to the early stages of periodontal disease,” continued Dr. Otomo-Corgel. “For patients who are diagnosed with periodontal disease, it’s imperative that they are encouraged to be completely honest about their drinking habits. This information can guide in determining appropriate treatment and next steps.” A full version of “Alcohol Consumption and Periodontitis: Quantification of Periodontal Pathogens and Cytokines,” study can be found in an upcoming print edition of the Journal of Periodontology.

Now in its seventh year, the Pride Institute’s “Best of Class” Technology Award continues unparalleled in its integrity and approach to recognizing excellence in dental innovation. In 2015, the VALO LED curing light, from Ultradent Products, Inc., is one of those lauded as “Best of Class.”

“To be honored as ‘Best of Class’ is a sign that a product has revolutionized, simplified, or advanced its category in a distinctive way,” said Dr. Lou Shuman, "Best of Class" founder. “The manufacturers represented here are driving the conversation for how dental practices will operate today and in the future. The foundation for our success in bringing attention to these products has always been our formula: technology leadership in dentistry, unbiased, and not for profit.”

“Best of Class” honorees are chosen by a panel comprised of leading voices in dental technology, who come together each year to discuss, debate, and decide what products merit recognition. All technology categories are considered, but if there is no clear differentiator that sets a product apart in its category, then no winner is selected. Panelists who receive compensation from dental companies are prevented from voting in that company’s category. Over the years, the panel has developed a rapport that makes space for important conversations about the value of different innovations and how evolving categories become more or less valuable to the general dentist. The spirited debate that follows results in a variety of products—obscure and well-known, basic and aspirational—being honored.

“Technology decisions can be expensive and confusing for many doctors. Our job as ‘Best of Class’ panelists is to eat, sleep, live, breathe, and use technology in our general practices in real, everyday dentistry. We also have a chance to show and discuss these products with dental students and colleagues,” said Dr. John Flucke, writer, speaker, and Technology Editor for Dental Products Report. “This allows us to provide recommendations that a doctor and staff can rely on to make informed decisions regarding their technology purchases.”

The panel consists of five dentists with significant knowledge of and experience in dental technology, including: Dr. Shuman; Dr. Flucke; Paul Feuerstein, DMD, writer, speaker and Technology Editor for Dentistry Today; Marty Jablow, DMD, technology writer and consultant for Dr. Bicuspid; and Parag Kachalia, DDS, Vice-Chair of Preclinical Education, Research and Technology, University of Pacific School of Dentistry.
Mike Simmons, Ultradent equipment brand manager says, “Ultradent is incredibly pleased and honored to receive this distinguished award for the 4th year in a row by such an esteemed and respected panel. Simply put, VALO delivers. It delivers a broadspectrum light that cures both camphorquinone and specialized proprietary photoinitiators. It delivers a uniformly collimated beam to cure a range of surfaces and working differences. It delivers accessibility, which translates to a more comfortable procedure for the patient. And most importantly, VALO delivers real value to the clinician—which is why it has been ranked #1 for four years in a row.”
The Pride Institute “Best of Class” Technology awards were launched in 2009 as a new concept to provide an unbiased, non-profit assessment of available technologies in the dental space. Through print and digital media coverage, the “Best of Class” message reaches the community of 150,000 dentists through multiple touch points—in print and online—educating them about the products. Honoree participation in the “Tech Expo” at the American Dental Association’s Annual Meeting offers face-to-face interaction with the companies as well as technology-centered education provided by members of the panel and the esteemed consultants of Pride Institute. Courses at last year’s 2014 meeting sold out. This year’s event will be held November 5–10 in Washington, DC.

New teeth may give some people renewed sense of happiness. For postmenopausal women with osteoporosis who are a greater risk of tooth loss, this is often the case, according to a new study. The Case Western Reserve University School of Dental Medicine study indicated that dental implants do wonders for this group of people. The information appeared in the Journal of International Dentistry. This study is part of a series of studies analyzing dental outcomes for women with osteoporosis. The research team looked at 237 women regarding their satisfaction with their replacement teeth and how their lives improved after receiving them. There were 23 survey questions that asked about various facets of their lives. The participants were from the Case/Cleveland Clinic Postmenopausal Wellness Collaboration. Osteoporotic women with one or more adjacent teeth missing (not counting wisdom teeth or third molars) were included in the study. The women had restoration work done such as implants, fixed partial dentures, and denture removal. There were also some who did not have any restoration work. The women with dental implants reported a higher satisfaction with all aspects of their lives. Fixed dentures produced the next greatest satisfaction, followed by false teeth. The women with no restoration work had the least satisfaction. This study shows that a patient’s satisfaction and happiness with the treatment’s aesthetics may be just as important as the return of functionally after undergoing a dental procedure.
A new study shows that internal stress works against crack propagation and increases the resistance of biostructure. An interdisciplinary team led by scientists of Charite Universitaetsmedizin Berlin looked at various aspects of dentin. As part of the study, engineers used internal stresses to strengthen materials for the specific technical purposes. Apparently evolution has been aware of this, which is why this has been put to use in natural teeth. Human teeth are not capable of repairing damage, which is unlike bones because bones are partially made of living cells. Human teeth are instead made of dentin, which is a bonelike material comprising mineral nanoparticles. The nanoparticles are embedded in tightly connected collagen fibers. This is why teeth are tough and damage-resistant. But prior to this study, it was unclear as to how crack propagation in teeth could be stopped. Researchers from Charite Julius-Wolff-Institute, Berlin have been working with partners from Materials Engineering Department of Technische Universitaets Berlin, MPI of Colloids and Interfaces, Potsdam and Technion - Israel Institute of Technology, Haifa, to further explore these biostructures. They conducted experiments in the mySpot BESSY facility of HZB in Berlin and examined the local orientation of the mineral nanoparticles using the nanoimaging facility of the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. The researchers determined that when the tiny collagen fibers shrink, the result is that the attached mineral particles are more compressed. They used changes in humidity to pinpoint how stress shows up in the mineral in the collagen fibers. The research team also analyzed the result if the tight, mineral-protein link is damaged by heating. In this case, the dentin in teeth becomes weaker. That’s why it’s crucial for the stress between particles and protein to be balanced to ensure the long-term survival of the teeth. This also shows why artificial tooth replacements may work well but they’re still not the same as regular teeth.
Brushing one’s teeth is apparently not as important as it used to be. Young people would rather spend their time using the dating app Tinder than brushing their teeth, according to a recent study. Careway Pharmacy recently conducted a study with 2,000 adults. About 40 percent of the participants ages 18 to 24 said they spent fewer than 60 seconds brushing their teeth. The same group said they spent about 90 minutes on Tinder. The study also showed that people ages 25 to 34 were most likely to brush twice each day. But 20 percent of that group said they regularly missed brushing in the morning or evening. This information doesn’t add up when you consider that a healthy smile is much more attractive than one with chipped, missing or stained teeth. If a person doesn’t maintain his or her oral health, he or she is also more susceptible to other health issues. Even spending only 2 minutes in the morning and at night can be the difference between being healthy and having some health issues. Dedicating that small amount of time to brushing can also aid in having that attractive smile that everyone covets.
