Scientists uncover genes that influence tooth development
Genes that influence tooth development in the first year of life have been identified by scientists.

The research team has also uncovered a link between the delayed appearance of milk teeth and the need for future corrective work.

The research, which involved teams from Imperial College London, the University of Bristol and the University of Oulu in Finland, has identified several genes which affect tooth development in the first year of life.

They found that babies who carried specific genetic variants tended to have fewer teeth by their first birthday than other children. Full PAPER

How to achieve best position for Microimplants by Park et al
The midpoints between the roots were located distally to the contact point and from the cervical to the apical areas. The lines connecting these midpoints from the cervix to the
apex of the roots in the mandibular arch had more distal inclination than in the maxillary arch.
Conclusions: To minimize root contacts, microimplants need to be inclined distally about 10-20 degrees and placed 0.5 to 2.7mm distally to the contact point to minimize root contact according to sites and levels, except into palatal interradicular bone between the maxillary first and second molars.

Dentists in LONDON 'sickest of all health professionals'
The free, confidential service for practitioners living or working in the London area was launched by the National Clinical Assessment Service amid concerns that some doctors and dentists were either struggling to access appropriate care or were suffering in silence rather than seeking proper medical help because of fears they would be stigmatised.
Dentists are the sickest of all health professionals, according to the head of an NHS service aimed at helping clinicians struggling with physical or mental illnesses. MORE

How to Select Short implants ?
The key to the implants' strength is their width, Dr. Urdaneta said. As long as they are at least 3 mm wide, they do not break, he said. Typically, such implants are embedded about 7.9 mm into the bone, but some are inserted only 5 mm deep. By contrast, long implants can be placed more than 11 mm into bone.
With short implants, "most impressive is what happens below the gum," he said. Some patients who wear these implants for five years have gained more than 1.5 mm of bone, according to Dr. Urdaneta.
Contrary to popular belief, he said, relatively large crown-to-implant ratios don't cause crestal bone loss. He cited a study in the International Journal of Oral and Maxillofacial Implants that compared bone loss of implants with different crown-to-implant ratios (JOMI, January-February 2005, Vol. 20:1, pp. 69-76). "Long implants and/or splinting can result in greater crestal bone loss," the study authors concluded. MORE

Want to deliver a healthy Clean baby ? Clean your teeth in time.
PREGNANT WOMEN have been warned not to ignore dental problems following the case of an unnamed woman with the common gum disease gingivitis who delivered a stillborn baby at 39 weeks.
Doctors were able to trace the oral bacteria in the 35-year-old mother’s mouth to bacteria found in the baby’s bloodstream, lungs and stomach.
The research was carried out by microbiologist Yiping Han in the Department of Periodontics at Case Western Reserve University School of Dental Medicine, Ohio.
The findings, published in the February issue of Obstetrics Gynecology , suggest that any disruption to the amniotic fluid could present a risk to both mother and baby – making the infection from gum disease a real risk.

Researchers from Queen Mary University of London have also found that bacteria from a woman’s mouth could be transferred through blood and amniotic fluid to her child while still in the womb. MORE

Teeth Show Evidence of Radiation Exposure
Researchers at Howard University in Washington College of Dentistry believe that tooth enamel stores important data about a person’s exposure to radiation. The team is developing Electron Paramagnetic Resonance (EPR) to determine the level of free radicals in substances, including tooth enamel.

What will this information be used for? The hope is that EPR can assist medical workers in triaging patients or dividing victims of radiation exposure into classes by the amount of radiation received. The new technology is minimally-invasive and would provide data useful in treating people exposed to radiation in an accident or by a “dirty bomb,” which refers to a radiation dispersal device.  MORE

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

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

Objective: To determine if there is a significant difference in the clinical outcomes of cases treated with 0.018-inch brackets vs 0.022-inch brackets according to the American Board of Orthodontics (ABO) Objective Grading System (OGS).

Treatment time and the ABO-OGS standards in alignment/rotations, marginal ridges, buccolingual inclination, overjet, occlusal relationships, occlusal contacts, interproximal contacts, and root angulations were used to compare clinical outcomes between a series of 828 consecutively completed orthodontic cases (2005–2008) treated in a university graduate orthodontic clinic with 0.018-inch- and 0.022-inch-slot brackets.
Conclusions: There were statistically, but not clinically, significant differences in treatment times and in total ABO-OGS scores in favor of 0.018-inch brackets as compared with the 0.022-inch brackets in a university graduate orthodontic clinic (2005–2008). FULL PAPER

Validity of Soft tissue cephalometrics ? Is Ceph needed to plan orthodontic treatment ?

World J Orthod 2009;10:301–304. 

Following conclusions were drawn from this study:
- Soft tissue analysis showed that measurements extracted from lateral cephalometric radiographs do not represent the true values to be found in a particular patinet.
- A single magnification factor can not be applied as a correction factor for the lateral cephalometric soft tissue measurements. 
Another study has earlier shown (European Journal of Orthodontics 30 (2008) 630–635) that cephalometrics are not required for orthodontic treatment planning, as they did not influence treatment decisions.

Orthodontists’ interest in smile design has dramatically increased as a result of both their collaboration with dentists in interdisciplinary treatment and as the potential of laser-assisted dentistry is more readily understood by orthodontists. The 810 nm diode laser, which has numerous benefits for orthodontic treatments. It is manageable in size and low in cost. Because in most cases only topical anesthesia is necessary.

Micromimplants for periodontally compromised patients
World J Orthod 2009;10:350–360. 

Gradual intrusion of the maxillary and mandibular anterior teeth was achieved with a relatively simple orthodontic force system. A significant profile improvement was observed during the 18 months of treatment due to the retraction and intrusion of the incisors in both arches. This intrusion was accomplished without any sign of apical root resorption. The mandibular incisors were uprighted 6.5 degrees, and their maxillary counterparts were uprighted 13.4 degrees. The 2-year follow-up examination revealed a stable result with an increase in periodontal attachment as well as esthetics and function. Conclusion: A combined orthodontic, periodontic, and restorative treatment approach with adequate patient motivation can lead to improved masticatory function, esthetics, and periodontal conditions.

The effects of lavender scent on dental patient anxiety
Community Dentistry and Oral Epidemiology-Volume 38 Issue 1, Pages 83 - 87
In a cluster randomized-controlled trial, patients' (N = 340) anxiety was assessed while waiting for a scheduled dental appointment, either under the odor of lavender or with no odor. Current anxiety, assessed by the brief State Trait Anxiety Indicator (STAI-6), and generalized dental anxiety, assessed by the Modified Dental Anxiety Scale (MDAS) were examined.
Analyses of variance (anovas) showed that although both groups showed similar, moderate levels of generalized dental anxiety (MDAS F(1,338) = 2.17, P > 0.05) the lavender group reported significantly lower current anxiety (STAI: F(1,338) = 74.69, P < 0.001) than the control group.
Conclusions: Although anxiety about future dental visits seems to be unaffected, lavender scent reduces present state of anxiety in dental patients.


Tooth decay in children has reached “epidemic” proportions in Australia
According to a report in the Daily Telegraph, tooth decay has reached “epidemic” proportions in NSW, with dental experts saying that teeth deterioration is forcing an increasing number of toddlers, as young as 18 months, to undergo dental work which entails expenditure in thousands of dollars.

Going by the information forwarded by dental experts, parents are spending up to $5,000 on crowns for their children whose teeth start showing signs of deterioration even before they start going to preschool.

Tooth loss and intakes of nutrients and foods: a nationwide survey of Japanese dentists
Community Dentistry and Oral Epidemiology Volume 38 Issue 1, Pages 43 - 49
This study analyzed the data from 20 366 Japanese dentists (mean age ± SD, 52.2 ± 12.1 years; women 8.0%) who participated in a nationwide cohort study from 2001 to 2006. The baseline questionnaire included a validated food-frequency questionnaire to estimate intakes of foods and nutrients. We computed the geometric means of daily intakes by the number of teeth, adjusting for age, sex, smoking, physical activity, and history of diabetes.
Conclusions: Tooth loss was linked with poorer nutrition even among dentists.
