Difficult ortho patients may have body dysmorphia
Orthodontists are all too familiar with the occasional hard-to-please patient. But some patients may be more than just difficult — they could be suffering from a psychiatric condition known as body dysmorphic disorder (BDD), according to a study in the American Journal of Orthodontics and Dentofacial Orthopedics-Feb 2011.
Education on BDD is crucial for orthodontists, especially those with a substantial volume of adult patients according to author of this study.
Warning signs
-Patients who perform certain compulsive behaviors or express obsessive thoughts, such as emphasizing that they want things to be perfect or “just right”
-Patients who count, tap, or repeat certain words or concerns over and over
-Patients who ask the same question over and over
-Patients who express how a specific flaw they want corrected makes them anxious or embarrassed, or it is all they can see when they look in the mirror — particularly when the flaw they’re so concerned with is a trivial or negligible dental flaw, such as an incipient dental rotation or minimal interdental spacing

Light weight maxillary complete denture-with thermocolThermocol being a light weight material can be left in the denture without compromising the integrity of the denture, avoiding the tedious effort to remove the spacer material from the denture. Moreover, the small window in the cameo surface in the previous techniques has potential for leakage between the heat polymerized resin and auto polymerized resin portions. This technique is simple to execute and allows control of spacer thickness.
A simplified technique for fabricating light weight maxillary denture using thermocol as a spacer that can be left in the denture without compromising denture strength. FULL TECHNIQUE

Dental pulp stem cells in regenerative dentistry -Odontology Jan 2011

Stem cells constitute the source of differentiated cells for the generation of tissues during development, and for regeneration of tissues that are diseased or injured postnatally. In recent years, stem cell research has grown exponentially owing to the recognition that stem cell-based therapies have the potential to improve the life of patients with conditions that span from Alzheimer’s disease to cardiac ischemia to bone or tooth loss. Growing evidence demonstrates that stem cells are primarily found in niches and that certain tissues contain more stem cells than others. Among these tissues, the dental pulp is considered a rich source of mesenchymal stem cells that are suitable for tissue engineering applications. It is known that dental pulp stem cells have the potential to differentiate into several cell types, including odontoblasts, neural progenitors, osteoblasts, chondrocytes, and adipocytes. The dental pulp stem cells are highly proliferative. This characteristic facilitates ex vivo expansion and enhances the translational potential of these cells. Notably, the dental pulp is arguably the most accessible source of postnatal stem cells   .LINK

Regenerative Endodontics- A case report


This case report describes the treatment of two pulpless immature maxillary central incisors. Conventional apexification techniques were not used. A regenerative technique based on literature to achieve revascularization was followed. This treatment approach involves disinfection of the canal space with topical antibiotics followed by blood clot induction from the periapical tissues. At the one year follow-up, significant root growth was achieved. FULL Report

MCI to crack down on doc-firm nexus- Dentists ?
Pharmaceutical companies may soon be officially allowed to sponsor medical conferences. However, they cannot pay the expenses of individual doctors like travel, room and board for conferences.
Also, the money that companies would pay for the event has to be given directly to the conference secretariat.
The secretariat can pay for the travel and hospitality only if the delegate is a post-graduate student or a faculty member. Individual delegates to the conference cannot be sponsored by the secretariat.
All medical conferences, workshops and training programmes will have to be first registered with Medical Council of India (MCI). All audited accounts of the conference will have to be submitted to MCI for scrutiny to make sure that no individual doctor’s trip was sponsored. Doctors also cannot take gifts from any pharmaceutical company that costs more than Rs 1,000.  TIMES NEWS

Denture paste poisoning now being investigated by FDA
This month, dentists nationwide were warned for the first time to be on the lookout for denture paste poisoning in a letter from the Academy of General Dentistry titled “The Tooth about Zinc.”
The FDA now admits it has received “numerous” complaints similar to one made by Marsha Hill of Irving, who was interviewed by WFAA last year.
“I can’t get out of bed, I can’t take care of my kids,” Hill said. “I can’t get a job. Yeah, yeah, it’s definitely had an impact on my life.”
She is among the many claiming denture paste poisoned her.
Denture wearers often use too much product, swallowing the excess. Federal health officials now confirm that can cause a toxic buildup of zinc. Zinc is an ingredient in several popular denture adhesives.
In some cases, zinc poisoning causes crippling nerve damage, called neuropathy. It can make walking and daily functioning difficult. NEWSLINK

Tooth palace in Making
Children across Britain are being asked to donate their milk teeth to create PALACES; a spectacular glittering sculpture made from crystal resin and decorated with retired pearly whites. The project is a part of an art-science collaboration that aims to inspire the nation with the regenerative potential of adult stem cells.
The PALACE will grow over time like a coral reef, to form a fantastical palace-like structure made of thousands of milk teeth donated by children around the UK.
Artist Gina Czarnecki and stem cell biologist Professor Sara Rankin from Imperial College London hope that thousands of children will contribute to their participatory art project.

Evolution of Tooth Brush
Tooth brush is essential part of each one of us today, what would be life without it ? Traces of the first toothbrush can be dated back as early as 3500 B.C.E. (before common era) and were thought to be used by the Egyptians and Babylonians. This piece of toothbrush history proves that this device is one of the oldest still used by man. The primitive form of the toothbrush was found in the pyramids of the Egyptians. India also has history of many indigenous methods.
These ancient civilizations used a “chew stick” to clean their teeth. This consisted of chewing on one end of the stick until the fibers of the wood formed a brush. These chewing sticks were made out of Salvadora persica branches, which were believed to have healing and antiseptic qualities. India common ones are known as Neem and Babul. More HERE
