Indian Dentist in UK nailed, Enamel defects are deadly, Revolution in Temporizing

Indian dentist in UK barred from treating women alone
Dr Surinder Hundle London-based cosmetic dentist, order of GDC reads:
 ‘You have admitted having had a sexual relationship with Patient A between about 2006 and September 2008. There are conflicting versions of events, in particular, about whether you or patient A initiated the relationship, and which of you ended the relationship.

‘Boundaries were transgressed so as to raise questions of public protection and the public interest. Any such behaviour must tend to bring the profession into disrepute because a sexual relationship between a dentist and his patient constitutes a breach of appropriate boundaries.' MORE

To Probe or NOT To Probe
Jonathon gave practical advice on techniques for use in the surgery and also maintenance tips for patients at home.
Many hygienists are reluctant to use a probe where an implant is present, but Jonathan assured his audience that using conventional probing with lightweight force would be unlikely to damage the peri-implant tissues, but would certainly help determine the health of gingival tissue.

‘Probing is essential for identifying the health of tissues around the implant. If there is a probing depth of more than 3mm, or bleeding on probing, you should administer antiseptic cleansing gel, antibiotics, or, in extreme cases, suggest regenerative surgery.' MORE

Late Baby Teeth May Mean More Orthodontic Visits
Several genes affect tooth development in the first year of life, according to the findings of a study conducted at Imperial College London, the University of Bristol in the UK and the University of Oulu in Finland. The research, published February 26 in the open-access journal PLoS Genetics, shows that the teeth of babies with certain genetic variants tend to appear later and that these children have a lower number of teeth by age one. Additionally, those children whose teeth develop later are more likely to need orthodontic treatment. FULL REPORT

Treat Canker sores (aphthous ulcer) with  Vitamin B 12
People with canker sores have much lower intake of vitamin B12 and folate than average, a study concludes.

Researchers at the University of Connecticut collected diet information on 100 people who had a history of canker sores. They compared this group of people to a national survey of more than 9,000 people. These people had completed a diet history, but did not have canker sores.

The canker sore group had much lower intakes of vitamin B12 and folate than the nationwide group without canker sores. Other studies have found vitamin B12 or folate deficiencies in some people with canker sores. In at least one study, people were treated for these deficiencies. Their canker sores either got smaller or disappeared altogether.MORE

Sweet tooth could mean something more serious
Children's response to intense sweet taste is related to both a family history of alcoholism and the child's own self-reports of depression, according to new research from the Monell Chemical Senses Center (Addiction, February 9, 2010).

Because sweet taste and alcohol activate many of the same reward circuits in the brain, the researchers examined the sweet preferences of children with a genetic predisposition to alcoholism. They also studied the influence of depression, hypothesizing that children with depressive symptoms might have a greater affinity for sweets because sweets make them feel better.

In the study, 300 children between 5 and 12 years of age tasted five levels of sucrose (table sugar) in water to determine their most preferred level of sweetness. The children also were asked questions to assess the presence of depressive symptoms, while their mothers reported information on family alcohol use. MORE

Bond Strength of different Adhesive systems

Etch-and-rinse adhesive AdperTM Single Bond 2 yielded high bond strength when applied to both normal and caries-affected dentin. The two-step self-etching adhesive Clearfil SE Bond generated the highest bond strength to ND among all adhesives tested but a significantly reduced strength when applied to CAD. For the one-step self-etching adhesives, Clearfil S3 Bond and iBond GI, the bond strength was relatively low regardless of the dentin type. SEM interfacial analysis revealed that hybrid layers were thicker with poorer resin tag formation and less resin-filled lateral branches in the CAD than in the ND for all the adhesives tested.
Conclusion:  The etch-and-rinse adhesive performed more effectively to caries-affected dentin than the self-etching adhesives. Full PAPER

New Material very effective for Dental Hypersensitivity, J D Res
The results of the dentin permeability tests showed that the novel mesoporous material exhibited a significant reduction in dentin permeability (p < 0.05), even under simulated pulpal pressure, as compared with our previously developed material, DP-bioglass, and a commercial desensitizing material, Seal & Protect®.

Successful Treatment of Early Implant Failure
Clinical Implant Dentistry and Related Research Feb2010
The study sample consisted of 18 implants presenting at 4–6 weeks postplacement with early progressive bone loss. Clinical examination indicated the presence of a fistula in the soft tissue covering the implants in most cases. Defects around the implants were curetted, exposed implant surfaces were mechanically debrided and treated with tetracycline solution, and the defects were filled with bone graft and doxycycline powder. Bioabsorbable membranes were used. Final crowns were placed after 6 months. The patients were followed for an average of 30 months.
Conclusions: Early detection and treatment of early progressive bone loss around dental implants are the key to saving early failing implants. The author recommends reevaluation visits 4–6 weeks postimplant placement to detect any signs of early failure so that immediate treatment can be undertaken if needed.

Which GP and sealer gives best performance in RCT ?
Triple O,Volume 109, Issue 2, February 2010, Pages e131-e135 
Four groups of premolars (n = 64) were instrumented to size 45/.04 ProFile and filled with laterally compacted gutta-percha cones or Resilon cones in association with AH Plus or Epiphany sealer. The specimens were stored for 2 weeks at 37°C and 100% humidity. After that, leakage was measured using the fluid filtration method and determined as μL/min · 10 psi.
Homogeneity of variance and multiple comparisons tests were performed and indicated that root fillings with the combination of gutta-percha cones and AH Plus sealer showed lower leakage values (P < .05) than the other groups.
Considering the experimental conditions and the results obtained, it was concluded that fillings made with gutta-percha cones in combination with AH Plus sealer had the best performance.

Biofilms: Discovery of a New Mechanism of Virus Propagation
Researchers at the Institut Pasteur and CNRS have shown for the first time that certain viruses are capable of forming complex biofilm-like assemblies, similar to bacterial biofilms. These extracellular infectious structures may protect viruses from the immune system and enable them to spread efficiently from cell to cell. "Viral biofilms" would appear to be a major mechanism of propagation for certain viruses. They are therefore emerging as new and particularly attractive therapeutic targets. MORE

Britain's not accepting students' visa applications in North India
From Monday, the UK's visa application centres in northern India will temporarily stop accepting visa applications for student visas. I much regret the need to take this step. But I am clear we had no choice.
One problem that we face in India is with unscrupulous agents. While there are many agents who offer a genuine and useful service to visa applicants, there are others who try to convince people that they can provide them with a route into the UK by the backdoor. MORE

Pre-procedural rinsing in reducing aerosol contamination
Results showed that a regimen of 30-seconds pre-procedural rinsing with 0.12% chlorhexidine gluconate before dental procedures consistently reduced colony-forming units than without rinsing due to the ability of antiseptic mouthwash to inhibit microbial growth. There was more aerosol contamination during scaling procedures than during the use of a high speed air turbine handpiece. The conclusion is that chlorhexidine is an effective primary measure in reducing aerosol cross-contamination when using dental devices in a dental set up. MORE

New Research finds way to Repair The After-Effects Of Gum Disease
Over recent years, Professor Ivanovski's research at the Griffith Institute for Health and Medical Research has been focussed on growing layers of cells such as stem cells and gingival (gum) fibroblasts for restoring damaged smiles.
"Previous work was involved in looking at the growth factors and optimal cell types for regenerating destroyed tissue."
"Now we are using new technology to harvest sheets of these cell cultures and transfer them safely to the surface of the tooth root," he said. Laboratory studies indicate that the cells can be successfully grafted with periodontal repair taking about six months.  MORE
