Smallest bikini ever made from Dental Floss
The stunning fitness model and ‘Miss Bikini America’  wore even less than usual, in what must surely be the world’s smallest swimsuit or practically nothing ?
It consisted on three tiny strips of gold sequins, tightly fastened together with some transparent thread that looked a lot like dental floss.
Jennifer wore her barely there swimsuit at a shoot on Miami beach yesterday.
The top and bottoms left almost nothing to the imagination, revealing a body that any woman would be proud of.

Sexy vampire adv to encourage young Brit men to visit dentists!
Called Want a Dentist after Dark, the video forms part of a social media campaign for NHS Portsmouth, an area which has poor levels of dental health.
Inspired by films and TV series such as Twilight, it features a victim being appalled by a vampire’s bad teeth.
The social media campaign follows research into the barriers preventing young people from going to the dentist.
NHS Portsmouth’s Lee Loveless said: “Traditional methods to engage young men haven’t worked. We have looked at what appeals to our target group.”
The tongue-in-cheek video, entitled Want a Dentist after Dark?, was originally produced for NHS Northamptonshire.
It has been adapted for Portsmouth which has traditionally had poor levels of dental health. BBC NEWS

Endo is EASY, GOOD Endo is NOT Easy

Nonsurgical endodontic therapy of a left maxillary first molar with three roots and eight root canals was successfully performed. This unusual morphology was diagnosed using a dental operating microscope (DOM) and confirmed with the help of cone-beam computed tomography (CBCT) images. Results: CBCT axial images showed that both the mesiobuccal and distobuccal root contained a Sert and Bayirli type XV canal, whereas the palatal root showed a Vertucci type II canal configuration.
Conclusions: The use of a DOM and CBCT imaging in endodontically challenging cases can facilitate a better understanding of the complex root canal anatomy, which ultimately enables the clinician to explore the root canal system and clean, shape, and obturate it
more efficiently. (J Endod 2011;37:715–719)- This paper is by Jojo Kottoor et al from Meenakshi Ammal Dental College and Hospital, Chennai, congratulations

Ragging scandal hits Govt. college
College authorities are busy inquiring into a ragging scandal that has rocked the campus. They received a letter from a former student last month complaining about alleged ragging he had to endure while in college.

Viraat Jayswal (name changed), a Pune resident, had enrolled in the college in September 2010 as a fresher but went back to his home town within four months without citing any reason. In February, he applied for cancellation of his admission and requested that all his original documents in college possession be handed back to him. A month later, he sent a letter to the college detailing the actual reason for his leaving the college. NEWsLINK

Erectile dysfunction and chronic periodontitis link
Researchers from the department of periodontics at the Government Dental College and Research Institute in Bangalor, India, studied 70 male subjects with a mean age of 35.3 ± 3.64 years who were clinically diagnosed with erectile dysfunction.
The subjects were given the Sexual Health Inventory for Men questionnaire and underwent penile color Doppler ultrasound. Researchers recorded periodontal parameters such as probing pocket depth and clinical attachment level.
Prevalence for chronic periodontitis among all erectile dysfunction subjects was highest among those with severe ED, and while association of CP and ED was found to be correlated positively. LINK

New Fiber-Reinforced Composite Material Offers Advancements In Oral Implants
Distribution of stress and strain to the jawbone is significantly changed after reconstruction with oral implants. How an implant using fiber-reinforced composite reacts has not yet been well tested. This biomechanical connection between implant and bone can be different for each patient and is hard to measure.
Therefore, this study used a three-dimensional finite element model constructed from a mandibular bone and an implant to test these materials. The model was subjected to stress loads of 50 N (Newton) in vertical and horizontal directions.
Although variances were observed for both the fiber-reinforced composite and the titanium materials with these tests, the composite performed well. The strain distribution demonstrated a clear difference between the two materials. The results show that the vertical load stress range of the fiber-reinforced composite implant was close to the stress level for optimal bone growth. More ON FRC

Increased risk of stroke after trigeminal neuralgia
Cephalalgia April 2011
There are no reports on the risk of stroke after trigeminal neuralgia (TN). The aim of this population-based follow-up study was to investigate whether the occurrence of TN is associated with a higher risk of developing stroke.
This study showed a significantly increased risk of developing stroke after TN. Further studies are needed to investigate the underlying mechanism of this association.

Self ligating brackets- DEMON are slow in correction of crowding EJO Apr 2011
This prospective study investigated the difference in clinical efficiency between Damon™ 3 self-ligating brackets (SLB) compared with Mini Diamond conventional ligating brackets (CLBs) during tooth alignment in straightwire fixed appliance therapy.
In the aligning stage, the CLB group showed significantly faster alignment of the teeth compared with the SLB group at the T1–T2 interval (P < 0.05). However, there were no differences at T2–T3, and T3–T4 for either group (P > 0.05). The CLB group showed 98 per cent crowding alleviation compared with 67 per cent for the SLB after 4 months of alignment and levelling. Mini Diamond brackets aligned the teeth faster than Damon™ 3 but only during the first month.

Remineralizing agents don’t hurt bleaching efficacy
Research presented last month at the International Association for Dental Research (IADR) meeting in San Diego found that adding calcium and fluoride to bleaching gels does not interfere with the whitening effect of the gels.
Adverse effects related to the use of bleaching agents on enamel include a reduction in enamel microhardness and some mineral alterations after bleaching procedures.
Previous studies have reported a decrease in the calcium concentration of enamel surface when high-concentrated hydrogen peroxide gels are used, she said. However, the resulting reduction in microhardness of bleached enamel can be reversed through exposure to saliva, she added.
“Nevertheless, these side effects can be reduced by adding fluoride or calcium to the bleaching gels,” Borges said. “Besides, remineralizing agents are added in bleaching gels as an attempt to reduce enamel solubility and tooth sensitivity.”

Biodegradable toothbrush
The new EcoBrushes and EcoFlossers are North America’s first biodegradable toothbrushes and flossers made from corn, wheat, tapioca and potatoes which are designed to decompose into organic material.
The handles of all Clean Idea dental products are made with a patented 100% compostable bio-resin which meets international standards for bioplastics and compostability (BPI (Biodegradable Products Institute), ASTM 6400D99, ASTM 6868, EN13432).
The resins will biodegrade within 180 days in a commercial compost facility. Unlike petroleum-based plastics, even when thrown into regular rubbish bins, Clean Idea products will eventually decompose into organic material. LINK

Homeopathy in Dentistry
Arnica is widely used in the treatment of trauma. It is of particular use in oral surgery to reduce post-operative pain and swelling, haemorrhage, and in all extensive restorative procedures. The medicine comes in tablet form and is dissolved under the tongue before and after treatment.
There is also a range of homeopathic mouthwashes available with the most effective being those which have been derived from Calendula, Myrrh or Propolis, a resin-like material from the buds of poplar and cone-bearing trees.
A solution derived from Plantain – a plant whose healing qualities are well established – when applied locally, is an excellent therapy for sensitive teeth, and will give immediate and long-lasting relief after just a few applications. MORE

Dentists more scary than snakes and spiders
Last month’s Adult Dental Health Survey which revealed half of adults – especially women – were classified as having moderate to extreme dental anxiety.
The Foundation asked 1,004 people – in the lead up to National Smile Month 2011 – what made them most nervous from a list including heights, flying, injections, doctors, snakes, spiders, going to hospital and visiting the dentist.
Over one in five people rated visiting their dentist as the thing that made them most nervous – more than any other category.
Overall, statistically, heights topped the poll of biggest fears, closely followed by visiting the dentist and going to the hospital.
Snakes were rated fourth and spiders came fifth.
In comparison to doctors, dentists also struggled.
The Foundation discovered that nearly 10 times as many people (22%) were made most nervous by their dentists, compared to their doctor (2%).
