Heroic Dentistry: How Yoseph got his smile back

The Heroic Dentistry series celebrates oral health care providers who, like PULPDENT founder Dr. Harold Berk, have made it their mission to save teeth and help patients live in comfort and smile with confidence.   

Yoseph left his native Ethiopia in the summer of 2012 to start a new life in the United States. The teenager settled in Las Vegas, Nevada and enrolled in Clark High School, where he honed his English skills and joined the school cross-country team. Along with the usual academic and extracurricular activities, Clark High offered its students another special service: basic dental care.

Through a partnership with Nevada-based Future Smiles, Clark High students, and those in other low income neighborhoods, can receive oral health screenings and education, dental hygiene prophylaxis, fluoride varnish, sealants, and referrals to area dentists. The program provides services to children living below the federal poverty guidelines, Medicaid/CHIP enrollees, and the uninsured and underinsured. PULPDENT has been a proud sponsor of Future Smiles and has provided pit and fissure sealants and fluoride varnish treatments for thousands of students like Yoseph across Nevada.

Yoseph soon proved to be a good student and an avid runner on the cross-country team. In late 2015, he fell during a cross-country practice and fractured teeth #8, #9 and #10. “I was so devastated when I looked at my face,” wrote Yoseph in a letter to Future Smiles. “I am usually a smiley person but after the accident I lost my smile.”

Yoseph’s broken teeth were not merely an aesthetic concern; it also hindered his speech. He did not have dental insurance, and his school contacted Future Smiles for assistance.

Future Smiles referred Yoseph to Dr. David Fife, a local endodontist who provides discounted services for their program. Root canals were performed, although the endodontist had some concerns about tooth #9, which he shared in a note to Dr. Byron Blasco, a nearby aesthetic and restorative dentist who would contribute his time to complete the restorative work:

“#9 has a horizontal root fracture and may not make it – it is mobile and hurting. I used an MTA-based sealer, so I am hopeful that it helps calm the bone down in the fracture area – we’ll see. #8 is fine and needs a crown.”

Fortunately, #9 appeared to react favorably to the endodontic treatment, and Dr. Blasco completed the case without further complications. Tooth #8 was built up with composite and received a full coverage E-max crown (IPS Ivoclar Vivadent). Due to the horizontal root fracture in tooth #9 and the poor long-term prognosis for retaining this tooth, #9 was restored with a direct bonded composite restoration, and Yoseph was informed that he would most likely require an implant at a later time.

Thanks to Future Smiles, the local endodontist and the aesthetic and restorative dentist, Yoseph got his smile back, finished his senior year with excellent grades, and is now a freshman at the University of Nevada at Reno. He plans to major in mechanical engineering and says, “Hopefully, I will graduate and contribute my part to society.”

Dentaltown Publishes 70-Year Recall

Dentaltown has published the longest case history ever reported in dental literature. The 70-year recall of a vital calcium hydroxide pulpotomy performed by Harold Berk, DDS in 1946 was reported in the February 2017 issue and appears online. The article shows the step-by-step technique for the surgical procedure.

Vital pulpotomy is the amputation of the coronal pulp tissue and placement of a pulpal dressing with the intention of maintaining the vitality of the radicular pulp. Dr. Harold Berk, a pioneer and early researcher in pulp biology and vital pulp therapy, reported on the 50-year recall of his first human pulpotomy (1996) in his book, Save That Tooth. Dr. Ali Maddahi saw the patient in 2016 and is the lead author of the 70-year report.

Dr. Berk is the inventor of Pulpdent Paste, the first premixed calcium hydroxide-aqueous methylcellulose pulpal dressing, widely used in vital pulp therapy and root canal therapy. He served on the faculty of Tufts University School of Dental Medicine from 1946-2005.

Dr. Christopher Ramsey sampled the ACTIVA BioACTIVE-BASE/LINER and CEMENT and sent a video with feedback to Larry Clark from Pulpdent. Ramsey, a general and cosmetic dentist from Florida, describes the ACTIVA BioACTIVE-BASE/LINER as “over the top,” noting that the product eliminates post-op sensitivity. Ramsey calls the cement an “all-in-one” and says units cemented with ACTIVA BioACTIVE are staying in place and show no signs of microleakage.

ACTIVA Receives 2017 Top Bioactive Product Award

The Dental Advisor 2017 Top AwardACTIVATM BioACTIVE-RESTORATIVETM received the Top Bioactive Product Award from THE DENTAL ADVISOR for the second year running in 2017. Dentist evaluators were impressed with ACTIVA BioACTIVE’s delivery system and esthetics, especially for anterior restorations, and found it to be an “excellent material to use for restorations and cores.”

Unlike traditional restorative materials, ACTIVA BioACTIVE stimulates apatite formation at the tooth-material interface which reduces sensitivity, guards against secondary caries, and seals margins against microleakage and failure. The material is moisture-friendly and contains a shock-absorbing rubberized resin component, and bioactive glass fillers that mimic the physical and chemical properties of natural teeth. Over 2 million restorations have been placed with ACTIVA BioACTIVE-RESTORATIVE since the product was launched in 2013.

“To be considered for an award, products must receive an excellent rating by THE DENTAL ADVISOR, as well as stand out from all others in the market place,” said Dr. Sabiha Bunek, The Dental Advisor’s Editor-in-Chief. ACTIVA BioACTIVE responds to pH cycles and an evaluator for THE DENTAL ADVISOR noted that “having a good uptake of calcium, phosphate and fluoride ions is a huge plus.” (The Dental Advisor Evaluator Comments, Top Product 2017).

In 2015, The Dental Advisor rated ACTIVATM BioACTIVE-RESTORATIVETM as excellent, with 5 plus (+++++) and a 98% clinical performance rating after the first year of a long-term clinical trial of 96 restorations. “The material performed extremely well at one year.” (The Dental Advisor Clinical Evaluation, Nov 2015). Click here to view the full report.

ACTIVATM BioACTIVE is the first esthetic, bioactive restorative that delivers all the advantages of glass ionomers in a strong, resilient, bioactive resin matrix that resists fracture, chipping and crumbling. ACTIVATM‘s rubberized resin component is more durable and fracture resistant than composites.

ACTIVATM chemically bonds to teeth, and releases more calcium, phosphate and fluoride than glass ionomers. It contains no Bisphenol A, no Bis-GMA and no BPA derivatives.

Pulpdent Celebrates 70 Years of Dental Innovation

PULPDENT Corporation enters its eighth decade as the world leader in esthetic bioactive restorative dental materials and the company’s mission of saving teeth and promoting good health date back even further.

Pulpdent 70th AnniversaryBy the time he was eleven years old, Harold Berk had found his calling: dentistry. Years later he told his family that as a young boy he “wanted to fix children’s teeth.”

Born in 1917 to a family of Eastern European immigrants, Dr. Berk’s studies brought him to the Forsyth Dental Infirmary in Boston, MA where he conducted research on the use of calcium hydroxide in vital pulp therapy. In 1947 Dr. Berk started a company to manufacture and market his recently developed Pulpdent Paste, a premixed calcium hydroxide paste still used by dentists worldwide today. The company was eventually called PULPDENT Corporation in honor of Dr. Berk’s original product.

From the beginning, Pulpdent was guided by Dr. Berk’s “mission to save teeth and … help my patients live in comfort and smile with confidence.” In the 1970s, Dr. Berk’s three sons, Ken, Fred and Don, took over management and operations of the company. Dr. Berk continued to serve as a consultant while maintaining a busy dental practice and teaching at Tufts Dental School.

Dr. Berk understood nature’s healing powers and saw it as his responsibility “to create an environment that is favorable for the natural healing process.” Dr. Berk’s sons explored new ways to develop dental products that mimicked nature and supported oral health. A series of innovations over a period of fifteen years culminated in 2013 with Pulpdent’s launch of ACTIVA BioACTIVE, a dental filling material that behaves much like natural teeth. The material is “bioactive” meaning it stimulates the formation of apatite (the building blocks of teeth), chemically bonds to teeth and helps seal them against decay. ACTIVA BioACTIVE has received many awards, including top performance ratings from The Dental Advisor in 2016.

Pulpdent’s offices and manufacturing facilities are based outside of Boston, MA, just a few miles from where Dr. Berk practiced and taught dentistry. Two of Dr. Berk’s grandchildren, Lewis and Leah Berk, recently joined the company, ensuring it will remain family run for another generation.

Pulpdent celebrates its 70th anniversary this year with renewed commitment to product innovation, clinical education and patient-centered care. To commemorate this milestone, Pulpdent has launched Heroic Dentistry, a clinical case series that showcases clinicians who combine innovation and compassion to deliver life-changing results for their patients, which will be featured on the Pulpdent website.
