WVU Research Shows Fear of Dentist Causes Problems for Patient:

“Every patient that I see, I try not to assume that they’re not afraid or they are afraid because there’s a lot of people that do surprise me,” said Tiffany Summerlin, a dental hygienist at the Monongalia County Health Department. “Some people that you wouldn’t imagine that they are afraid. I can’t make assumptions about anyone. Some people are just deathly afraid of coming to the dentist and it’s important for me to validate those fears and talk them through it.”  .. Read More

Dentist Sues Airline for sending him to Grenada rather than Granada

An American dentist who said he is of Spanish-Jewish heritage is suing British Airways for flying him to Grenada rather than Granada.

Edward Gamson and his partner believed they had first-class tickets to fly from London to Granada, in Spain, but once off the ground they discovered that the plane was heading for the Caribbean island of Grenada.

Gamson is suing British Airways for $34,000 in damages. He said the airline refused to reimburse the couple’s tickets and put them on the next flight headed back to England and then on to Spain.

“I have a lifelong interest in Islamic art. I’m also of Spanish Jewish heritage, so it was something I had always wanted to do to visit Granada and the Alhambra,” Gamson told the British newspaper The Independent on Sunday.

Indian Origin Dentist Behind The Revolutionary Laser Coaxed “Dentin Regeneration”

Indian Origin Dentist Behind The Revolutionary Laser Coaxed “Dentin Regeneration”

In an email interview with Dr.Syed Nabeel, editor-in-chief of  Dental Follicle- The E Journal of Dentistry ,Dr.Praveen Arany – The man behind the revolutionary – Laser Coaxed Dentin Regeneration – talks about his research that will perhaps change the treatment approach of a dental patient. Dr.Praveen Arany, graduated from Rajiv Gandhi University of Health Sciences, Bangalore. following which he moved to Harvard. His detailed CV is here.

DF: Please explain us about the news headline which reads “Researchers use light to coax stem cells to repair teeth”?

PA:      Our recently published work demonstrates the ability of low power laser treatment to promote differentiation of resident adult dental stem cells (DSC) to form tertiary dentin. Essentially, it aids in the tooth repair-regeneration process in response to injury by utilizing the normally present endogenous factor and cells. This form of therapy is called Low Level Light Therapy (LLLT) or more appropriately, Photobiomodulation (PBM).

DF:  How does Laser coax stem cells?

PA  :    The mechanism of this phenomenon was carefully elucidated demonstrating that the photonic (laser) energy first induced a photochemical reaction generating Reactive Oxygen Species (ROS) that, in turn, is ‘sensed’ by a specific amino acid residue on a growth factor, TGF-beta 1, which activates it. The activated endogenous growth factor that affects the differentiation of DSCs to induce dentin.

DF:  In which year did you first find the effect of laser on, dentin of rodents?

PA:      We began working on the dentin induction via lasers in 2006 when I joined Prof. Mooney’s lab at Harvard. Prior to this, we had made an observation in a human clinical trial of the ability of laser treatment to induce TGF-beta1 expression in oral healing tissues. This was part of my Master’s thesis submitted to Rajiv Gandhi University in 2001 while I was doing my oral pathology program at KLE’s Institute of Dental Sciences, Belgaum and Indian Institutes of Science, Bangalore.

DF: Is the dentin formed after laser treatment same in composition and morphology?

PA:      The newly formed mineralized tissue is the ‘tertiary or osteodentin’. This newly formed dentin was carefully characterized based on its organic (non-collagenous matrix proteins) and inorganic (calcium hydroxyapatite).

DF: Can this technology be readily used in clinics to treat patients?

PA:      Yes. Laser technology is already a familiar tool in the dental clinic (as also in dermatology, oncology and ophthalmology) but usually with high dose. This specific application uses low doses and the key question remains the safety and effectiveness of the clinical dosing. The unraveling of one of the mechanisms gives us a good handle on outlining the ‘therapeutic window’ that my current group at the National Institutes of Dental and Craniofacial Research (NIDCR), along with many others around the world, are working towards this singular goal.

DF:  How do you think your discovery will impact the dental industry?

PA: Dentistry today largely relies on a ‘restorative’ approach and we do a great job via fillings, root canals, crowns, dentures and implants. The new wave of dentistry using biomaterials and medical devices, including laser technology, are largely focused on ‘regenerative’ approaches that are aimed at promoting regeneration of natural soft and hard tissues to replace the diseased or destroyed ones.

DF: Many news headlines are deceiving, like one said “dentists can re-grow your teeth now.” Can you be specific in mentioning the advantages, applications and limitations of this new technology?

PA: This work, like many scientific research performed today, involves extremely sophisticated techniques and complex methods spanning multiple specialist fields. The popular press attempts to make these stories palatable so that the common man can grasp the essence of these findings and appreciate its implications for their healthcare.

In our interactions with the press, the specific explanation of our research was that the technique is able to ‘regrow a part of tooth’ – dentin – and that its significance was in preserving the natural tooth structure and hence, preventing its eventual loss. This has been misrepresented as ‘replacing Root Canal Treatments’ as well as ‘Regrow the missing teeth’.

We have not attempted to regenerate other key tooth structures such as Enamel, Cementum, Periodontal ligaments or alveolar bone. The inability of make enamel has also been incorrectly stated as a limitation of this study and this is erroneous. Not only are there a lack of readily available Ameloblasts in the clinical scenario, our current understanding of the cues to driving enamel differentiation are limited. In contrast, the role of TGF-beta in dentin biology, especially with DSCs are robustly established.

The major limitations of our current technique, as we outline in our paper, is the wide spread tertiary dentin induction due to the large area of laser-tissue interactions and the lack of the tubular dentin structure, we observe pulp stone-like, lamellar deposits. Moreover, these studies were performed in animal models (rat and mice) and human teeth in culture; human clinical dosing is currently ongoing and requires more work.

DF:   Please tell us more about, how you would like to take this research ahead and how do you think ,this would impact on how a patient is treated in a decade from now?

PA: Since 2012, the current research in my group is focused on outlining the clinical safety and efficacy parameters and we are in the process of submitting our work for publication. This would be a major step forward in bringing this technology to the clinic. It is hoped that the mechanism and clinical dosing parameters will spur the adoption of this technology for dentin regeneration in clinical applications such as dentin pulp capping and dentin desensitization. Further, the potent utility of a non-invasive device, lasers, to control endogenous ROS and TGF-beta1 has significant implications in various lab and clinical situations. We have extended our observations to Mesenchymal stem cells (accepted in Journal of Dental Research) and other biological scenarios such as wound healing, reduce pain and inflammation and immunomodulation (ongoing research studies) are being actively explored.

DF:   You are perhaps one of the most celebrated dentists today, how does it feel to be one?

PA: It is gratifying to see the recognition by our peers, and specifically pleasing to see the attention this is bringing to dental research in terms of regenerative medicine.

DF:  We are proud that you are of Indian Origin and perhaps graduated from the same university as I did – what would be your message to the alumni and students of Rajiv Gandhi University of Health sciences.

PA: This work was only possible due to the significant support from my past and current mentors, colleagues and my family. It did originate in India as a dental resident! My message to the current students and residents would be to think beyond the ‘why?’ (education), to ask ‘why not?’ (research) to improve care for our patients.

DF: Please tell us more about yourself and your family.

PA: My parents and family are based in Bangalore. My wife is also a RGUHS dental alumnus and we have a 9 year old daughter. When I am not working, I like to spend time with my family and play badminton.

DF: Last – what is your take home message for the world wide readers of – Dental Follicle – The E Journal of Dentistry  and DentistryUnited.com?

PA: To be a successful (dental) professional, you have to be pragmatic about your limitations and seek to push beyond barriers, usually time and/or money. This requires both strong intellectual tenacity and moral courage that persevere through the toughest of times when you doubt yourselves, a natural sequelae of research. Seek to surround yourselves with good people whom you can learn from and stay focused on a worthwhile, altruistic goal.
