Dental Technology: Buying New Toys for Your Dental Office

By John Sarno DMD | Dental News


Breakthrough Clinical as Editorial Director Stacey L. Simmons, DDS, explains why she loves her new digital scanner and dental imaging, as well as what she looks for in buying a new piece of dental technology for her practice.

It’s clear that the digital and technological world has firmly induced its footprint in dentistry, and if you’re like me, you don’t want to get left behind. That clearly arrives at a price and again, if you’re like me, you have to study world markets for the most recent and greatest gadgets and gismos, assess your finances, and then decide whether to take the plunge and purchase said toy( s ). My colleague and co-editorial director, Dr. Josh Austin, is a specialist in dental technology.

Well, the most recent addition to my digital armamentarium has not frustrated. I recently bought the Carestream CS 3600 digital scanner. What do I like best? This part of dental imaging equipment didn’t transgress my budget, its small and easy to use, it integrates with my software( Eaglesoft ), it scans promptly, customer support is readily( and easily) available, my crown/ bridge and scanned denture instances come back quickly and accurately, there are no associated fees, I don’t have to mess with impression material, and my patients desire it! They get so excited about learning a scanned image of their tooth that can be flipped around on the screen–all of their friends only have to know about it. Talk about a win-win.

I’ve only been using it 2 months and I’ve not yet tapped into the full potential of the scanner, but that will come with time. Bottom line: I’m never going back to impression material.

Sleep apnea is something I’m trying to continually learn more about, and we’re fortunate to have the president of the American Academy of Dental Sleep Medicine as an author this month. Dr. Harold A. Smith writes about how we can bridge the gap between dentists and physicians when treating our sleep apnea patients. Teamwork is key to a successful

Retreat or apicoectomy ? What are the factors that we need to consider when a root canal is not successful? Dr. Michael Zuroff, an endodontist out of Michigan, is back to give us his perspective.

I know you’ll enjoy the pathology case from Ghana in West Africa. Give us your thoughts. You only can’t make this stuff up.

Happy fall, my friends!

Anti-inflammatory versus Antibacterial – Treating Periodontal Cancer

By John Sarno DMD | Dental News , Dental Treatments

A lot has been written lately about managing the inflammatory aspects of periodontal disease. After all, it is the body’s inflammatory reaction that is causing hard and soft periodontal tissue destruction.

When a patient presents to the office with periodontitis, an anti-inflammatory protocol may be indicated. Another way of thinking about this is revealed, however, if we go further back in the disease process. What induces mobilization of the inflammatory reaction in the first place? Bacterial invasion of the gingival epithelial cells is the trigger that ignites the body’s immune-inflammatory reaction, which is accompanied by the freeing of enzymes that destroy the gums and bone.

Using anti-inflammatory meds as part of the therapy plan appears to have virtue, but the primary objective should be knocking down the cause–namely the bacteria. How do we know how effective our bacterial reduction efforts were? We don’t unless we offer salivary testing both pre- and postop.

This is not rocket science, but sometimes the simplest answers are the most difficult to see.

TMJ Stem Cells Used to Mend Cartilage Tissue in the Joint

By John Sarno DMD | Dental News

Researchers from the Columbia University College of Dental Medicine have identified stem cells within the temporomandibular joint( TMJ) that can construct new cartilage and mend damaged joints.

According to the National Institutes of Health, up to 10 million people in the United States, primarily women, have TMJ agitations. Options for therapy currently include either surgery or palliative attention which addresses symptoms but can’t renovate the damaged tissue. Dr. Embree’s acquires suggest that stem cells already present in the seam “could’ve been” manipulated to repair it.

Cartilage helps to cushion the seams and allows them to move smoothly. The type of cartilage within the TMJ is fibrocartilage is also found in the knee meniscus and in the disc between the vertebrae. Because fibrocartilage cannot regrow or heal, gash or malady that impairs this tissue can be achieved through permanent disability.

Medical investigates have been working to use stem cells, immature cadres that can develop into various types of tissue, to renovate cartilage. Devoted the challenges presented by displacing donor stem cells, such as the possibility of rejection by the recipient, investigates are especially interested in finding ways to use stem cells already living in the body.

” The implications of these acquires are wide-ranging ,” said Dr. Mao,” including for clinical cares. They suggest that molecular signals that govern stem cells may have therapeutic have applied for cartilage and bone regeneration. Cartilage and certain bone defects are notoriously hard to heal .”

Dr. Mao is co-director of the Center for Craniofacial Regeneration at Columbia. His own study with stem cells has renovated teeth and the meniscus, the pad of cartilage within the knee joint, and the TMJ in 2003.

In a series of experiments described in the brand-new report, Dr. Embree, Dr. Mao, and their colleagues isolated fibrocartilage stem cells( FCSCs) from the seam and showed that the cadres can structure cartilage and bone, both in the laboratory and when implanted into swine.” I didn’t have to add any reagents to the cadres ,” Dr. Embree said.” They were programmed to do this .” And while some comings to renovating disabled tissue compel increment points or biomaterials for the cadres to germinate on, she memo, the FCSCs developed and ripened spontaneously.

Dr. Embree and her team also identified a molecular signal, Wnt, that saps FCSCs and effects cartilage deterioration. Introducing a Wnt-blocking molecule announced sclerostin into degenerated TMJs in swine energized cartilage increment and healing of the joint.

She and her peers are now searching for other small molecules that could be used to inhibit Wnt and promote FCSC growth. The suggestion, according to Dr. Embree, will be to find anti-retroviral drugs with minimum side effects that could be injected right into the joint.

Children with adolescent idiopathic arthritis can have stunted jaw increment that can’t be treated with existing medicines, Dr. Embree memo. Since the TMJ is a growth center for the mouth, the brand-new study is available through approaches for analysis these children and lead to a better understanding of how the mouth germinates and develops. While orthodontists currently rely on clunky technologies such as headgear to modify mouth increment, she lent, the findings could point toward ways to modulate increment on the cellular level.

Ultimately, Dr. Embree and her unit say the findings could lead to approaches for repairing fibrocartilage in other seams, including the knees and vertebral disc.” Those the different types of cartilage have differing cellular ingredients, so we would have to really analyze the molecular underpinnings regarding how these cadres are modulated ,” health researchers said.

This investigation was supported by awards from the National Institutes of Health( K99DE022060-01A, 5R00DE0220660, R01DE021134, S10RR027050, S10OD020056, and NO1-DE-22635 ).

Injected mix of Bone-augmenting Agents Causes New Bone Growth in Mouse Jaw

By John Sarno DMD | Dental News , Dental Treatments

Researchers centered at Tokyo Medical and Dental University( TMDU) deliver a protein/ peptide combination using an injectable gelatin carrier to promote bone constitution in mouse jawbones

Tokyo- The part of the jawbone containing tooth sockets is known as alveolar bone, and its loss over term or following dental ailment may eventually result in tooth loss. While dentures can be used as a tooth substitution, the mechanical stimulation for the purposes of the dentures effects farther bone loss. An alternative and more permanent solution is strongly hoped for. Recombinant human bone morphogenetic protein 2( BMP -2) has been used to stimulate osteogenesis( bone constitution) in humen, but high levels can cause inflammation and tumor progress. Hence, workers such as peptide remedies for accelerating bone augmentation need to be developed, even in the presence of lower levels of BMP -2. Additionally, there are no known means of arousing regional bone augmentation without acting surgery.

The peptide OP3 -4 has been shown to inhibit bone deterioration and stimulate the differentiation of cadres( osteoblasts) that figure bone. Now, an international team centered at Tokyo Medical and Dental University has injected a gelatin-based gelatin carrying OP3-4 and BMP -2 into mice jawbones to provoke regional augmentation of bone all over the injection area. The examine was recently reported in the Journal of Dental Research .

Employ of this injectable gelatin-based gelatin to carry the workers avoids the need for surgical implantation and resulted in no expand or other such complications in the experimental mice. The investigates observed individual regions of increased bone mass all over the BMP -2+ OP3-4 injection area that was larger than that considered to be in mice injected with BMP -2 alone, or with other masteries. This mass too had a significantly higher bone mineral material and concentration

Microscopic examination revealed the deposition of calcified tissue (mineralization) throughout the newly formed bone of BMP-2 + OP3-4-treated mice.

“Mineralization of the outer region evidently took place before that of the inner region,” lead author Tomoki Uehara says (Image2). “We speculate that the size of the new bone is determined before calcification starts, and that OP3-4 plays an important role in making a regeneration site at the early stage of bone formation.”

Corresponding author Kazuhiro Aoki adds: “OP3-4 further enhanced the number of bone-forming cells induced by BMP-2 treatment, and greatly increased the expression of genetic markers of bone formation.”

Diagnosis and Treatment for Breakthrough Clinical Oral Pathology

By John Sarno DMD | Dental News , Dental Treatments

This article first appeared in the newsletter, DE’s Breakthrough Clinical with Stacey Simmons, DDS. Subscribe here.

Last month I presented the oral pathology action of a healthy 40 -year-old woman who presented with a six-year history of a recurrent anterior mandibular growth. She experienced no hurting but was ashamed of being seen in public. She had two prior surgeries to compensate the original precondition. When the lesion was previously removed it was small and asymptomatic. The first surgery was done six years ago and the second largest surgery two years after that. After the second largest surgery, individual patients decided to pursue herbal medication because the regular medication wasn’t relenting a definitive arise. She returned 3 years later with no improved and the current rendition.


These are my differentials:

  • Ameloblastoma
  • Fibro-osseous lesion
  • Fibrous dysplasia
  • Ossifying fibroma

Definitive diagnosis: Recurrent ameloblastoma of anterior mandible

Recurrent ameloblastoma is a rare, benign tumor of the odontogenic epithelium occurring much more commonly in the mandible than the maxilla. Although it is rarely malignant or metastatic, it progresses slowly and can cause severe abnormalities of the face and jaws. Ameloblastoma has abnormal cell growth, which easily infiltrates and destroys surrounding bony tissues.

Incidence rates per million for ameloblastoma globally: (1)

  • Black males: 1.97
  • Black females: 1.23
  • White males: 0.19
  • White females: 0.45

Treatment: Wide surgical intervention is required to effectively treat this condition. A bilateral hemimandibulectomy was done for this particular patient.

Periodontal Disease Prevention: Identify Bacteria Through Salivary Diagnostics

By John Sarno DMD | Dental News , Dental Treatments

In his DentistryIQ blog, a Making the Oral-Systemic Connection, a Richard H. Nagelberg, DDS, says he has  a revolutionary idea: identify the bacteria in patients who don’t have periodontal disease.a He goes on to explain the ideal protocol for combatting periodontal disease and how you can begin to offer diagnosis and treatment in your practice use the information that is available regarding risk factors namely, salivary diagnostics.

The hallmark of prevention is to determine risk factors for disease and then to oversee those risk factors before the disease, provision, or occasion comes. This is why there is so much existing information regarding the risk factors for myocardial infarction. Periodontal canker is no exception. Identify the biggest risk factor for the periodontal disease–namely, the specific bacteria a patient keeps in his or her mouth–and then administer it with an antimicrobial etiquette before periodontal canker rears its unpleasant head.

Patients who have a strong family history of periodontal canker would be an ideal place to start. Since you can reasonably predict that these individuals have some degree of hoisted gamble for periodontal canker, why not catch out which oral bacteria they have? And the same for patients with gingivitis who have not yet changed to periodontitis. If the test shows very little bacteria at low levels, we are capable of concluding that, at this time, the patient is not at risk for the developed at periodontal canker, and vice versa. This just acquires sense.

Receding Gums: Treatment Alternatives and Causes

By John Sarno DMD | Dental News , Dental Treatments

Treatment for receding gums

Most cases of mild gum recession do not need therapy. Dentists may simply give advice about prevention and offer to monitor the gums. Teaching people how to brush gently but effectively is a good early intervention.

For people who do need therapy, a number of options are available :
[teeth with braces] Orthodontics are one method of therapy for receding gums. Desensitizing agents, varnishes, and dentine bonding agents: These aim to reduce any sensitivity that may develop in the exposed tooth root. This treats the nerve symptoms and helps to keep normal oral hygiene by allowing brushing of sensitive teeth to continue Composite restoration: Tooth-colored composite resins are used to cover the root surface. They can also close black gaps between teeth, as shown in these before-and-after depicts from the British Dental Journal. Pink porcelain or composite: This is the same pink color of the gums. Removable gingival veneers made from acrylic or silicone. Orthodontics: Treatments designed to move the position of teeth can correct the gum margin. Surgery: Tissue is grafted from elsewhere in the mouth and heals over the gum recession.

The gums safeguard the fragile tooth roots from bacteria, plaque, and other means of decomposition.

The gums are also known as the gingivae. The gingiva is the moist pink tissue in the mouth that gratifies the base of the teeth. There are two such gums- one for the upper, and one for the lower set of teeth.

The gingiva is a dense tissue with a good furnish of blood vessels beneath a moist surface. The surface is called mucous membrane. It is joined to the rest of the mouth lining but is pink instead of shiny red.

The gums tightly surround the teeth up to the neck of each one and are firmly attached to the jaw bone. The gums usually cover the roots of the teeth, protecting them as they are more fragile than the rest of the teeth.

Gingival recession exposes the fragile tooth roots to bacteria, plaque, and other means of decay.
Why do gums recede?

Poor oral hygiene and periodontal disease connected to gingival recession. But receding gums can happen in people with good standards of oral hygiene, too.

Broadly, there are two causes of receding gums. Physical wear of the gums Inflammation of the gum tissues- this is a reaction of the immune system Inflamed gums known as gingivitis. This condition can lead to periodontitis Periodontitis ensues in spaces between the gums and teeth and loss of connective fibers and bone around the tooth roots. This leads to retreat gums Appearance Fear of tooth loss Sensitivity due to exposed tooth roots

Tooth Enamel Structure and Composition Revealed in 3-D Nanoscale Maps

By John Sarno DMD | Dental News , Dental Treatments

Using nanoscale technology, researchers have, for the first time, produced detailed 3-D maps of the composition and arrangement of mature human tooth enamel. The maps demonstrate the position of atoms critical to the process of tooth decay.
The new analyze makes detailed information about important trace ions in the tough arrangement of tooth enamel.The team of material and arrangement engineers and dentists- from the University of Sydney in Australia- produced the 3-D maps applying a relatively new microscopy technique called atom probe tomography.

The researchers describe their work in a newspaper published in the journal Science Advances and suggest it should help improve oral hygiene and to prevent caries or tooth decay.

According to the World Health Organization( WHO ), 60-90 percent of schoolchildren and virtually 100 percentage of adults worldwide have dental cavities, which result via the progressive dissolving of dental enamel.

Human dental enamel is the hardest tissue in the body. It protects teeth from the wear and tear of daily grinding and munching as well as from chemical attack.

Scientists have already established that the mechanical strength and resistance to fatigue of dental enamel comes from its complex hierarchical arrangement of sporadically organized bundles of hydroxyapatite( HAP) nanowires.
Potential for new treatments to protect tooth enamel

The new analyze makes detailed information about important trace ions in the tough arrangement of tooth enamel.

Fast realities about tooth decay

Rates of tooth decay have fallen significantly in the United States over the last 40 times, except in young children, where they have recently started rising again 42 percentage of U.S. children aged 2-11 have decay in their primary teeth 92 percent of U.S. adults aged 20-64 have had tooth decay in their permanent teeth; 26 percentage have untreated decay.

Written “Report Card” Decreases Dentists’ Antibiotic Prescriptions

By John Sarno DMD | Dental News , Dental Treatments

Dentists are less likely to prescribe antibiotics after they experience a personalised report detailing their past prescription writing rates, according to a randomised restraint test of UK dentists published in PLOS Medicine , by Linda Young, NHS Education for Scotland, UK, Jan Clarkson, University of Dundee and Craig Ramsay, Health Services Research Unit, University of Aberdeen, and colleagues.

Dentists prescribe about 10 percentage of the antibiotics dispensed in UK community pharmacies. Previous considers discovered  that, despite clear clinical guidelines, they often prescribe antibiotics in the absence of clinical desire. To experiment an” audit and feedback” intervention to reduce these improper prescriptions, the RAPiD( Reducing Antibiotic Prescribing in Dentistry) test relied on dental prescribing and care claim data that was already routinely collected by the National Health Service. The investigates haphazardly allocated all 795 antibiotic prescribing general dentist rehearsals in Scotland( a total of 2566 dentists) to either receive or not experience a graph plotting their monthly antibiotic prescribing rate. A random subset of practices in the involvement group also received a written behavior change theme repetition national recommendations.

At the start of the test, the full amounts of the number of antibiotics prescribed per 100 NHS treatment declare were 8.3 in the limit group and 8.5 in the involvement radical. Over the 12 months following the start of the involvement, dentists in the limit radical rehearsals prescribed antibiotics at a rate of 7.9 per 100 declares, and dentists in the involvement radical rehearsals at a rate of 7.5, representing a 5.7% reduction in antibiotic prescriptions in the involvement radical relative to the limit radical. Additionally, dentists who received a written behavior change theme had an even greater reduction, of 6.1% relative to involvement dentists who did not receive such message.

While the findings suggest that accommodating individualized graphical feedback is coming from routinely collected data can reduce the antibiotic prescribing rate of dentists, it was not possible to evaluate the impact on the quality or appropriateness of dentists’ antibiotic prescribing in this study.

” The feedback provided in this study is a fairly straightforward, low-cost public health and patient safety intervention that could potentially help the part healthcare profession address the increasing provoke of antimicrobial opposition ,” the authors say.

This study was conducted as part of the TRiaDS program of implementation research which is funded by NHS Education for Scotland( NES ). The Health Services Research Unit which is funded by the Chief Scientist Office of the Scottish Government Health and Social Care Directorates.

Professor Unveils First Data on Dental Fillings that Will Repair Tooth Decay

By John Sarno DMD | Dental News , Dental Treatments

The first data on dental fillings that  are able  to actively fix tooth decay is putting forward Professor Robert Hill. Professor Hill is Chair of Physical Sciences at the Institute of Dentistry at Queen Mary University of London and co-founder and administrator of research at BioMin Technologies.

Over 80 percent of specific populations in the UK has at least one filling, with seven being the average while eight million holes are fitted with amalgam each year.

This data, indicating smart fixing of tooth decay, prolonging living conditions of composite fillings and reducing the need for mercury-based amalgams indicates a significant step forward in tooth restorative materials.

Professor Hill outlines how new bioactive glass composites are unique in their ability to freeing fluoride as well as the significant quantities of calcium and phosphate that would be required to sort tooth mineral.

Professor Hill explains that while current dental fillings include inert materials, the data on the new bioactive glass composite shows that it interacts positively with the body rendering minerals that replace those lost to tooth decay.

” Our scientists and dentists at Queen Mary University of London supplanted the inert tooth filling materials with our new bioactive glass, explained Professor Hill.” Not merely did this bioactive glass composite remineralize the partly rotted teeth, but it also makes an alkaline context that deters the bacteria that made the initial decay.
