Dentists in UK attack Ugly Betty, Dentist/Ortho Condemed in News

Dentists attack Ugly Betty ( Jassie Jaisi koi Nahin )



Dentists have described the makers of Ugly Betty, the Channel 4 show, as irresponsible because its lead character has worn braces on her teeth for too long.
British orthodontists said they were worried TV show Ugly Betty could discourage young viewers from seeking corrective dental treatment.
Now in its third season on Channel 4, Betty - played by actress America Ferrera - is still wearing heavy "train track" braces. Full Report

Orthodontist/Dentist Cheated me
By Lasya Shashimohan, in middle page of Deccan Herald on July 17,09

I was paralysed with bewilderment and dismay. It was not my image I beheld but Bugs Bunny’s. I remembered my prior set of pretty teeth and wept at their untimely extraction and this monstrous jutting out eyesore had been gelled with permanent cement. I quietly walked off, aesthetically uglier and many a thousand poorer. Read Full news

Australian endodontists' perceptions of single and multiple visit root canal treatment,
IEJ July 2009

Aim: To ascertain endodontist's point of view (treatment philosophy, rationale and preference) regarding single- and multiple-visit root canal treatment. To identify the basis on which the choice is made and how the information necessary for the choice is acquired.

Methodology: Endodontists registered with the dental practice board of every state in Australia were contacted, and if they agreed to participate, they were interviewed either face to face or by telephone. The following topics were addressed in an interview lasting 15 to 20 min: demographics, current clinical procedures, treatment rationales and preference. A hypothetical scenario was posed to investigate which treatment regimen they would prefer to deliver if biological concerns were eliminated from consideration.

Results: Fifty-two endodontists (71% of all Australian endodontists) agreed to participate in the study. Almost all (51/52) participants had performed single-visit root canal treatment, but very few routinely performed it. A majority of participants were willing to provide single-visit treatment where patients had time constraints, and in vital cases (including elective endodontics). The most powerful factor of influencing practice change was interpersonal contact with colleagues. Publications in academic journals have a weak influence in practice change.

Conclusions: Australian endodontists strongly prefer multiple-visit over single-visit root canal treatment even in cases where biological concerns are not an issue. Operator preference rather than biological or patient considerations appear to be the primary determinant of treatment choice. If you want to do Endo in single visit CLICK HERE

Magnification devices for endodontic therapy, Does it Help ?

There are no data to draw a sound conclusion on the effect of adopting either a microscope, an endoscope, or magnifying loupes for better visualisation in endodontic therapy, in terms of clinical outcomes. Though the use of magnification devices has often been associated with technical advantages for the operator and with an improved management of the root canal due to a better visualisation of the operative field, it still has to be demonstrated that their use may lead to an improved treatment success rate. More long-term well-designed randomised trials with a large sample size are urgently needed to address the issues of the present review. Full Review

ORAL HEALTH AND INFLAMMATION IN PATIENTS WITH END-STAGE RENAL FAILURE
Perit Dial Int 29(4): 472-479, 2009
76 Peritonail Dialysis (PD) patients, 100 Hemodialysis (HD) patients, and 111 Controls were included in the study. SFR (milliliters/minute) was measured in stimulated whole saliva, SpH was measured using the Merck indicator, and SBC was measured according to the method of Ericsson: 1 mL whole saliva was added to 3 mL 0.005 N HCl and a stream of air was passed through this mixture for 20 minutes. Finally, DMFT index and PI values were calculated.

PD patients have higher SFR, SpH, and SBC values than HD patients; however, higher DMFT index and higher numbers of filled teeth were observed in PD patients. Compared to healthy controls, patients on dialysis had worse dental and periodontal findings, which might have a role in microinflammation in this group of patients. More Here

Influence of Rotational Speed on the Cyclic Fatigue of Rotary Nickel-Titanium Endodontic Instruments, Journal of Endodontics,Volume 35, Issue 7, July 2009, Pages 1013-1016

During the preparation of curved canals, rotary nickel-titanium (NiTi) instruments are subjected to cyclic fatigue, which can lead to instrument fracture. Although several factors may influence the cyclic fatigue resistance of instruments, the role of the rotational speed remains uncertain. This study was intended to evaluate the effects of rotational speed on the number of cycles to fracture of rotary NiTi instruments.

ProTaper Universal instruments F3 and F4 (Maillefer SA, Ballaigues, Switzerland) were used in an artificial curved canal under rotational speeds of 300 rpm or 600 rpm. The artificial canal was made of stainless steel, with an inner diameter of 1.5 mm, total length of 20 mm, and arc at the end with a curvature radius of 6 mm. The arc length was 9.4 mm and 10.6 mm on the straight part. The number of cycles required to fracture was recorded. Fractured surfaces and the helical shafts of the fractured instruments were analyzed by scanning electron microscopy.

The results showed approximately a 30% reduction in the observed number of cycles to fracture as rotational speed was increased from 300 to 600 RPM (p < style="font-weight: bold;"> increase in rotational speed significantly increases chances of instrument fracture.

Want to die early, Screw up your Oral Health

Oral health is an integral part of general health; oral health contributes to and is influenced by a nexus of inputs from biological, psychological, and social functioning. Little is known about the relationship between markers of oral health and subsequent survival in late life.

This study found Oral health was significantly associated with subsequent survival in a sample of oldest-old individuals, although psychosocial factors were stronger predictors. MORE here

Temporary orthodontic anchorage devices for improving occlusion
Orthodontics & Craniofacial Research, Volume 12 Issue 3, Pages 195 - 205

Studies at Orhodontics Dept at Baylor have shown that successful and consistent clinical results are possible with MI (Microimplant) use. Although iatrogenic trauma may occur during the placement of MI, a translational research model has provided data used to develop a placement protocol in order to avoid this dilemma. Absolute skeletal anchorage is a reality with MI use and can be used for successful orthodontic outcomes in the correction of Class II bimaxillary protrusion malocclusions to ideal Class I occlusions. Moreover, meticulous care has been shown to be essential with treatment planning and during placement of MI. Significant and extensive damage can occur with poor placement while healing is possible following minor trauma. Start using microimplants today.

CVD has a wide range of categories, which affect adults in the United States every day including high blood pressure, coronary heart disease, stroke, and heart failure. A recent study that will be cited during the presentation explored the existence of bacteria known to cause periodontitis and the growth of blood vessel walls, which is a symptom of CVD. After examining the subjects used, the investigators found a positive connection between the growth of blood vessel walls and the existence of bacteria found in dental plaque, causing periodontitis.

Tooth Jewellery and now Tooth Tattoos, Tooth loss leads to Cancer

Tooth Tatoos

You may be familiar with tooth jewellery ? The popular one for quite a while has been the brand known as skyce. These are small crystals looking like diamonds and are fixed on front teeth to give a shine to your smile. If you are not familiar you can click here to learn more. As if this was not enough you now have tooth tattoos.

American tattoo artist Steve Heward, who is also a dental technician, has taken the art of tattooing from the body to the mouth and has made it a huge success. Heward, who has been practising his art since 1979, has also made crowns for a few famous people, including a candidate for the US presidency in 2000.

The tooth artists at Heward Dental Lab can create custom hand-painted artwork and paint celebrities on your tooth. "The work can take from five minutes to an hour. But I usually spend half an hour," said Heward.

And what are the damages? "For the artwork itself, I usually charge about $75 to $500 depending on the subject matter," said Heward.

"My crowns can last a lifetime. And removing the tattoos is also a brief and painless process."

Studying thousands of patients, Japanese researchers have found a strong link between tooth loss and increased risk of three cancers esophageal, head and neck, and lung. They suggest that preservation of teeth may decrease risk of developing these diseases.

In the May issue of Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research, scientists from Aichi Cancer Center in Nagoya and Nagoya University Graduate School of Medicine speculate that bacterial infection and inflammation resulting from poor oral care that leads to tooth loss could also be driving development of these cancers. Periodontal disease is known to increase risk for stroke and heart disease.

"Tooth loss is a common consequence of chronic bacterial infection and may, therefore, serve as a surrogate for chronic infection and inflammation, which in turn may be important to the pathogenesis of cancer," said the study's lead author, Akio Hiraki, Ph.D., a researcher at the Aichi Cancer Center.

Researchers measured rates of 14 different cancers and rates of tooth loss in 5,240 cancer patients in Japan, and compared those rates among 10,480 matched cancer-free participants. The researchers specifically found that people with tooth loss were 136 percent more likely to develop esophageal cancer, had a 68 percent increased risk of developing head and neck cancer and a 54 percent greater chance of developing lung cancer. The researchers also found that the rate of cancer increased proportionally to the number of teeth a patient had lost.
Conclusion:
There is a significant positive association between tooth loss and the risk of head and neck, esophageal, and lung cancers after adjustment for potential confounding factors. The findings indicate that preventive efforts aimed at the preservation of teeth may decrease the risk of these cancers.

The use of visual assessment of dental radiographs for identifying women at risk of having osteoporosis: the OSTEODENT project published online on triple O, May 2008

Can you identify risk of osteoporosis from Intra oral radiographs? According to this article there is very high (90%) chance of predicting by seeing the trabecular density in premolar region.

Objective

The objective of this study was to investigate the diagnostic accuracy of visual assessment of the trabecular pattern in intraoral periapical radiographs to identify female subjects at risk of having osteoporosis.
Study design

Six hundred female subjects underwent intraoral periapical radiography of the maxillary and mandibular premolar region. Five observers assessed the trabecular pattern as dense, heterogeneous, or sparse, with the aid of reference images. All patients received a central dual energy x-ray absorptiometry (DXA) examination of the hip and lumbar spine.
Results

With sparse trabecular pattern as indicative of osteoporosis, mean specificity was high (91.6 for the upper jaw and 90.8 for the lower jaw) while the sensitivity was low (28.2 for the upper and lower jaw). The mean intraobserver agreement was comparable for radiographs of the upper and lower jaw (median κw 0.53 and 0.57, respectively).
Conclusion

Visual assessment of the trabecular pattern in intraoral periapical radiographs of premolar regions is a potential method to identify women at risk of having osteoporosis.

Microimplant screws for Anchorage

Friends,

MIA is an extremely valuable modality. It helps in your routine treatment and also enables to treat those difficult cases that we thought not treatable by orthodontics. It also improves outcomes in many cases and cuts treatment time. Long ago we had posted several cases on www.healthmantra.com/ic/ , one case was of correction of anterior cant of occlusion

Now there is a wonderful article on correction of post cant by use of MIA, it is in Aug issue of AJODO. here is the abstract and one pic

Introduction: Facial asymmetry is a major complaint of orthodontic patients. In those with severe facial asymmetry, combination treatment of LeFort I osteotomy and mandibular surgery was commonly used. This article demonstrates the usefulness of titanium screws for orthodontic anchorage to intrude the molars in 2 patients with facial asymmetry and canted occlusal plane. Methods and Results: The first patient was a woman, aged 29 years 6 months, with mandibular protrusion and canted occlusal plane; she was treated with molar intrusion and intraoral vertical ramus osteotomy. During presurgical orthodontic treatment, a titanium
screw was implanted in the zygomatic process, and the molars were intruded for 6 months by using an elastic chain of 200 g. After intrusion, the molars were intruded 3.0 mm, and the canted maxillary occlusal plane was improved. The second patient was a young man, aged 16 years 5 months, with mandibular deviation and canted occlusal plane; he was treated with a combination of titanium screw anchorage and intraoral vertical ramus osteotomy. A miniscrew was implanted in the alveolar bone, and the orthodontic load began immediately after placement surgery by using an elastic chain. After 5 months of intrusion, the molars
had been intruded by 3.0 mm. Conclusions: Compared with 2-jaw surgery, this method of molar intrusion is less invasive, involves less psychological stress, is less expensive, and results in less postoperative discomfort. Therefore, treatment with titanium screws for molar intrusion to correct a canted occlusal plane could become a new treatment strategy for patients with facial asymmetry.
