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.

Detection of Early-Stage Pancreatic Cancer from Saliva
Dr. James Farrell, who manages patients with all stages of pancreatic cancer, I was eager to work with David Wong and his team at the dental school to explore the possibilities it could yield in diagnosing this disease."
In the study, the researchers successfully linked changes in the molecular signatures found in human saliva to the presence of early-stage pancreatic cancer. MORE

Maxillary second molar with 5 roots and 5 canals evaluated using cone beam Imaging
Triple O, Volume 109, Issue 2, February 2010, Pages e162-e165
This case report presents the endodontic management of maxillary right second molar exhibiting 5 roots and 5 root canals. The diagnosis was confirmed with the help of cone beam computerized tomography (CBCT). The article also describes the varied morphology associated with maxillary second molar and the use of a high-end diagnostic imaging modality like CBCT in diagnosing and negotiating these anatomic variations.

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

Psychosocial Problems Are Common in Children With Dental Fear
Children and adolescents with severe dental fear often come from families with a turbulent background. It is also more common that they have had counselling contact with a psychologist. These are the conclusions of research carried out at the Sahlgrenska Academy at the University of Gothenburg, Sweden. MORE

Tough Times ahead for Dental/ Medical colleges ?
Dental/Medical colleges found using brokers to get clearance to start post-graduate or under-graduate medical courses will face withdrawal of their recognition or may be debarred from admitting new batch of students for two years.
Health minister Ghulam Nabi Azad had also called for surprise checks in colleges by the Medical Council of India to assess standards. "Random checking should become the order. If the institutes know when the team will visit them, they will have everything in place. MORE
The central government has recognised post-graduation courses being conducted by the government dental college in the Himachal Pradesh, specialties in oral and maxillofacial surgery, periodontics, community dentistry and orthodontics have been recognised. MORE

Mobile will be all you NEED
Schmidt, Google CEO predicted that in three years, if not sooner, smartphones would pass global PC sales - "a remarkable achievement".
"Mobile web adoption is proceeding at eight times faster than the equivalent point 10 years ago for the desktop," said Schmidt.
"Half the new internet connections are for mobile devices. From a Google perspective, there are more Google searches on mobile than on desktop in emerging countries like Indonesia." MORE
