Darby Dental Supply Donates Massive Truckload of Supplies to the Philippines

Truckload Full of Darby and Darby Vendor Products
Sent Directly to Typhoon Haiyan Survivors

Jericho, NY (November 20, 2013) – For its latest philanthropic endeavor, Darby Dental Supply, LLC, the largest all-telesales national distributor of dental merchandise, donated a full truckload of relief supplies to survivors of Typhoon Haiyan in the Philippines. 

Jam-packed with numerous containers of dental and hygiene products and various infection control items including gloves and respirator masks, the truckload of contributed supplies were used to support the survivors of Typhoon Haiyan, the second-deadliest Philippine typhoon recorded in history. The natural disaster claimed the lives of nearly 4,000 people in the Philippines alone, with an estimated 1,200 still missing.

The situation in the Philippines is just truly devastating and we knew we had to act quickly," remarked Liz Meyers, Vice President Marketing & Purchasing at Darby Dental Supply.  Hopefully the many items that we’ve contributed will address some of the sanitization issues that are taking place right now and be welcome by the survivors who are currently suffering a great deal. We couldn't just sit and watch TV and observe what is happening. Based on what we’ve seen through all the media coverage, the people in the Philippines just absolutely need everything; they were left with nothing and they're fighting for survival."

Though Darby Dental Supply acted alone in its most recent relief efforts for the Philippines, throughout the years the company has partnered many times with Physicians for Peace, a nonprofit organization that supports and empowers healthcare professionals working with the world’s underserved populations. 

Darby has been partnering with the nonprofit organization for quite some time now and has been a regular contributor, benefitting countless healthcare facilities around the world. With the help of Physicians for Peace, Darby most recently contributed a large amount of dental and hygiene supplies to Hôpital Albert Schweitzer in Haiti, and has helped various Physicians for Peace partners in the Dominican Republic, Malawi, the Philippines, and the West Bank. 

However, Darby Dental Supply’s past diverse philanthropic efforts include both local and international relief efforts. The company has adopted a “think globally, act locally” philanthropic philosophy, encouraging its employees who want to help the less fortunate to make a donation to their local Red Cross chapter. Most recently, Darby employees contributed to national Red Cross efforts in order to help those affected by the recent tornado in Oklahoma, and also placed an emphasis on local Long Island residents who were affected by Hurricane Sandy in 2012.

The company is also a huge supporter of the military, providing numerous contributions throughout the years to U.S. troops deployed overseas. In addition, Darby provided much-needed medical supplies to a makeshift shelter in Kesennuma, Japan that was devastated by an earthquake and tsunami.

Periodontal disease prevalence is higher in certain populations; Public health programs needed to improve periodontal health of U.S. adults

November 22, 2013 – Chicago – A report recently released by the Centers for Disease Control and Prevention (CDC) includes, for the first time, a discussion of health disparities and inequalities within periodontal disease prevalence in the United States. The report, “CDC Health Disparities and Inequalities Report — United States, 2013,” is the second in a series to highlight discrepancies across a variety of diseases by sex, race, ethnicity, income, education, disability status and other social characteristics.

The report finds that while nearly half of U.S. adults aged 30 or older have periodontal disease, the prevalence is significantly higher in non-Hispanic Blacks and Mexican Americans compared to non-Hispanic Whites. In addition, periodontitis is higher in men than in women; in people with less than a high school education; in people of lower income levels; and in current and former smokers. The report is based on an analysis of the 2009-2010 National Health and Nutrition Examination Survey (NHANES).

The American Academy of Periodontology (AAP) has been working closely with the CDC since 2003 to determine the extent, severity and prevalence of periodontal disease in the U.S. According to Dr. Stuart J. Froum, DDS, President of the AAP, clinical professor and Director of Clinical Research in the Department of Periodontics and Implant Dentistry at New York University Dental Center, the inclusion of periodontal disease in this report indicates a significant public health concern.

“Almost 65 million US adults have some form of periodontal disease, and certain populations are more vulnerable than others,” says Dr. Froum. “I commend the CDC for drawing attention to the disparities that exist within periodontal disease prevalence. These findings support a need for both local and national public health programs to improve the periodontal health of all adults, regardless of age, race or education.”

The AAP recommends that all patients receive a comprehensive periodontal evaluation on an annual basis as a way to effectively assess for disease. “The insidious and sometimes asymptomatic nature of periodontal disease means that many patients may have periodontal disease, but do not know it. As dental professionals, it is crucial we ensure that our patients are being screened annually via a comprehensive periodontal evaluation to determine their disease status and treat accordingly.”

Protection from periodontitis and related chronic diseases

28 October 2013 Antimicrob. Agents Chemother. doi:10.1128/AAC.01375-13
American Society for Microbiology

A drug currently used to treat intestinal worms could protect people from periodontitis, an advanced gum disease, which untreated can erode the structures - including bone - that hold the teeth in the jaw. The research was published ahead of print in Antimicrobial Agents and Chemotherapy.
Current treatment for periodontitis involves scraping dental plaque, which is a polymicrobial biofilm, off of the root of the tooth. Despite this unpleasant and costly ordeal, the biofilm frequently grows back. But the investigators showed in an animal model of periodontitis that the drug Oxantel inhibits this growth by interfering with an enzyme that bacteria require for biofilm formation, says corresponding author Eric Reynolds, of the University of Melbourne, Australia. It does so in a dose-dependent manner, indicating efficacy.
The researchers began their search for a therapy for periodontitis by studying the symbioses of the periodontal pathogens, using genomics, proteomics, and metabolomics, in animal models of periodontitis. They soon found that the periodontal biofilm depended for growth on the availability of iron and heme (an iron-containing molecule related to hemoglobin), and that restricting these reduced levels of the enzyme, fumarate reductase. Since Oxantel was known to inhibit fumarate reductase in some bacteria, they then successfully tested its ability to inhibit fumarate reductase activity in Porphyromonas gingivalis, one of the major bacterial components of periodontitis biofilms. Fumarate reductase is absent from humans, making it an ideal drug target.
They also showed that Oxantel disrupted the growth of polymicrobial biofilms containing P. gingivalis, Tannerella forsythia, and Treponema denticola, a typical composition of periodontal biofilms, despite the fact that the latter alone is unaffected by Oxantel.
The researchers found that treatment with Oxantel downregulated six P. gingivalis gene products, and upregulated 22 gene products, all of which are part of a regulon (a genetic unit) that controls availability of heme.
Periodontitis affects an estimated 30-47 percent of the adult population with severe forms affecting 5-10 percent. It also increases the risks of diabetes, heart disease, stroke, arthritis, and dementia, says Reynolds. These risks arise due to the pathogenic bacteria that enter the blood stream from periodontitis, as well as from the chronic inflammation caused by this disease, he says. Additionally, periodontitis correlates with increased risk of cancers of the head and neck, the esophagus, the tongue, and the pancreas, the investigators report.

Concentrations of and application protocols for hydrogen peroxide bleaching gels: effects on pulp cell viability and whitening efficac

Available online 13 November 2013
In Press, Accepted ManuscriptNote to user




to assess the whitening effectiveness and the trans-enamel/trans-dentinal toxicity of experimental tooth-bleaching protocols on pulp cells.


Enamel/dentin discs individually adapted to trans-well devices were placed on cultured odontoblast-like cells (MDPC-23) or human dental pulp cells (HDPCs). The following groups were formed: G1–no treatment (control); G2, G3, and G4–35% H2O2, 3 × 15, 1 × 15, and 1 × 5 min, respectively; and G5, G6, and G7–17.5% H2O2, 3 × 15, 1 × 15, and 1 × 5 min, respectively. Cell viability and morphology were evaluated immediately after bleaching (T1) and 72 h thereafter (T2). Oxidative stress and cell membrane damage were also assessed (T1). The amount of H2O2 in culture medium was quantified (Mann-Whitney; α=5%) and colour change (ΔE) of enamel was analysed after 3 sessions (Tukey's test; α=5%).


Cell viability reduction, H2O2 diffusion, cell morphology alteration, oxidative stress, and cell membrane damage occurred in a concentration-/time-dependent fashion. The cell viability reduction was significant in all groups for HDPCs and only for G2, G3, and G5 in MDPC-23 cells compared with G1. Significant cell viability and morphology recovery were observed in all groups at T2, except for G2 in HDPCs. The highest ΔE value was found in G2. However, all groups presented significant ΔE increases compared with G1.


Shortening the contact time of a 35%- H2O2 gel for 5 min, or reducing its concentration to 17.5% and applying it for 45, 15, or 5 min produce gradual tooth colour change associated with reduced trans-enamel and trans-dentinal cytotoxicity to pulp cells.
Clinical Significance: The experimental protocols tested in the present study provided significant tooth-bleaching improvement associated with decreased toxicity to pulp cells, which may be an interesting alternative to be tested in clinical situations intended to reduce tooth sensitivity and pulp damage.

Brånemark Novum® immediate loading rehabilitation of edentulous mandibles: 11-year retrospective study

Tealdo T, Menini M, Bevilacqua M, Pera F, Capalbo V, Pera P. Brånemark Novum® immediate loading rehabilitation of edentulous mandibles: 11-year retrospective study. Clin. Oral Impl. Res. 00, 2013; 17 doi: 10.1111/clr.12287




Short-term results indicated that the Brånemark Novum® protocol (Nobel Biocare AB, Goteborg, Sweden) allowed successful rehabilitation of mandibular edentulism with immediately loaded implants. Yet, long-term studies are lacking. The aim of the present retrospective study was to report the 11-year outcomes for patients treated according to this protocol.

Material and methods

Four patients treated according to the Brånemark Novum protocol (Nobel Biocare AB) were followed-up to evaluate implant and prosthesis cumulative survival rate (CSR), implant stability (RFA), marginal bone loss by periapical radiographs, probing depth (PD), and possible complications. Clinical and radiographic parameters were evaluated immediately after completion of the treatment and 1, 5, and 11 years after loading.


The 11-year implant and prosthesis CSRs were 100%. Implant stability (RFA values) remained stable over the 11-year follow-up. Small bone resorption was found next to distal implants (median 1 mm) after 11 years, while central implants showed greater bone resorption (median 4.5 mm). The PD (mean 3.75 mm at 11 years) grew together with marginal bone loss. One implant complication was detected on a central implant (crater-form bone destruction), and 10 prosthetic complications (fractures of resin or teeth), 80% of which registered on the same parafunctional patient.


The 11-year results demonstrated that the Brånemark Novum protocol (Nobel Biocare AB) is a predictable technique with favorable long-term outcomes. This was a rigid protocol, which could be applied only in patients with specific anatomical characteristics of the lower jaw, but it had the merit of indicating the key factors for full-arch immediate loading rehabilitations.

Coronal microleakage of endodontically treated teeth with intracanal post exposed to fresh human saliva

Journal of Applied Oral Science
Print version ISSN 1678-7757
J. Appl. Oral Sci. vol.21 no.5 Bauru Sept./Oct. 2013 

The aim of this study was to investigate the coronal microleakage of endodontically treated teeth prepared to receive an intracanal post and teeth with an intracanal post but without a prosthetic crown and exposed to contamination by fresh human saliva.

A mechanical-chemical preparation following the step-back technique was carried out in 35 extracted single-rooted human teeth. The teeth were randomly divided into five groups: G1=root canals instrumented, obturated, and prepared to receive an intracanal post (N=10); G2=root canals with cemented posts but without coronal sealing (N=10); PC1=positive control root canals instrumented and open (N=5); PC2=positive control 2 root canals without instrumentation and open (N=5); and NC=negative control healthy teeth (N=5). The crowns were removed except for the control group of intact teeth. The root canals were obturated and sterilized with cobalt 60 gamma irradiation and were then adapted in an apparatus using a Brain Heart Infusion (BHI) medium and fresh human saliva for contamination. Microbial growth was indicated by the presence of turbidity in the BHI liquid medium.

Data were submitted to the Kaplan-Meier Survival Analysis and the Holm-Sidak statistic method, which observed an index of 90% of microleakage in root canals after 24 hours for G1 and 70% of microleakage in samples at the end of 40 days for G2.

The results show that root canals with an intracanal post but without a prosthetic crown can be recontaminated when exposed to fresh human saliva in a short period.

Can mandibular bone resorption predict hip fracture in elderly women? A systematic review of diagnostic test accuracy

Gerodontology 2013; doi:10.1111/ger.12077 


The aim of this systematic review was to determine the diagnostic accuracy of the mandibular cortical width measurements and porosity in detecting hip osteoporosis.


All of the included studies used measurements on panoramic radiographs.

Materials and methods

Studies were included if they compared the radiographic measurements (or index tests) with central dual energy X-ray absorptiometry (DXA) of the hip as the reference standard. A measure of diagnostic accuracy such as sensitivity and specificity or area under the receiver operating characteristic curve was also required for inclusion.


Seven studies were identified. Meta-analysis was not possible because of the heterogeneity of the studies. The studies all demonstrated moderate diagnostic accuracy.


If a patient with a thin or porous mandibular cortex is identified by a chance radiographic finding, additional clinical risk factors need to be considered and the patient referred for further investigation with DXA where necessary.

Bringing needed immune cells to inflamed tissue to treat gum disease

The red, swollen and painful gums and bone destruction of periodontal disease could be effectively treated by beckoning the right kind of immune system cells to the inflamed tissues, according to a new animal study conducted by researchers at the University of Pittsburgh. Their findings, published this week in the early online version of the Proceedings of the National Academy of Sciences, offer a new therapeutic paradigm for a condition that afflicts 78 million people in the U.S. alone.
Periodontal disease currently is treated by keeping oral bacteria in check with daily brushing and flossing as well as regular professional deep cleaning with scaling and root planing, which remove tartar above and below the gum line. In some hard-to-treat cases, antibiotics are given. These strategies of mechanical tartar removal and antimicrobial delivery aim to reduce the amount of oral bacteria on the tooth surface, explained co-author and co-investigator Charles Sfeir, D.D.S., Ph.D., director, Center for Craniofacial Regeneration and associate professor, Departments of Periodontics and Oral Biology, Pitt's School of Dental Medicine.
"Currently, we try to control the build-up of bacteria so it doesn't trigger severe inflammation, which could eventually damage the bone and tissue that hold the teeth in place," Dr. Sfeir said. "But that strategy doesn't address the real cause of the problem, which is an overreaction of the immune system that causes a needlessly aggressive response to the presence of oral bacteria. There is a real need to design new approaches to treat periodontal disease."
In the healthy mouth, a balance exists between bacteria and the immune system response to forestall infection without generating inflammation, said senior author Steven Little, Ph.D., associate professor and chair of the Department of Chemical and Petroleum Engineering, Pitt's Swanson School of Engineering. But in many people, a chronic overload of bacteria sets up the immune system to stay on red alert, causing harm to the oral tissues while it attempts to eradicate germs.
"There is a lot of evidence now that shows these diseased tissues are deficient in a subset of immune cells called regulatory T-cells, which tells attacking immune cells to stand down, stopping the inflammatory response," Dr. Little said. "We wanted to see what would happen if we brought these regulatory T-cells back to the gums."
To do so, the researchers developed a system of polymer microspheres to slowly release a chemokine, or signaling protein, called CCL22 that attracts regulatory T-cells, and placed tiny amounts of the paste-like agent between the gums and teeth of animals with periodontal disease. The team found that even though the amount of bacteria was unchanged, the treatment led to improvements of standard measures of periodontal disease, including decreased pocket depth and gum bleeding, reflecting a reduction in inflammation as a result of increased numbers of regulatory T-cells. MicroCT-scanning showed lower rates of bone loss.
"Mummified remains from ancient Egypt show evidence of teeth scraping to remove plaque," Dr. Little noted. "The tools are better and people are better trained now, but we've been doing much the same thing for hundreds of years. Now, this homing beacon for Treg cells, combined with professional cleaning, could give us a new way of preventing the serious consequences of periodontal disease by correcting the immune imbalance that underlies the condition."
Next steps include developing the immune modulation strategy for human trials. In addition to Drs. Sfeir and Little, the research team included Ph.D. candidate Andrew J. Glowacki,, Sayuri Yoshizawa, D.D.S., Ph.D., Siddharth Jhunjhunwala, Ph.D., all of the University of Pittsburgh; and Andreia E Vieira, Ph.D., and Gustavo P. Garlet, D.D.S., Ph.D., of Sao Paulo University, Brazil.

When your cell phone battery dies... Power Rocks Magic Stick to the rescue.

Being on the road lecturing sometimes can be a drain, not just physically but on my cell phone battery. Having a iPhone where the battery cannot be replaced puts me at a disadvantage when I have those long days on the exhibit floor and dinners and more afterwards. Long days have meant having to be careful with cell phone usage. The last thing I wanted was a dead battery when I was trying to get a cab via Uber and being stranded on a street corner.  On my previous iPhone 4s I purchased a Mophi case and would have to swap cases before leaving on a trip.  For my new iPhone 5s I am going to be trying the Power Rocks Magic Stick.  This should give me plenty of extra battery power and slip nicely into my bag or pocket. I will post a review up once I give it a work out.
