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.
