Georgia anesthetist accused of molesting patients

Atlanta nurse anesthetist has been charged with molesting and sodomizing anesthetized patients in dental and medical offices, and police say the videotaped abuses could involve 100 or more victims.

Paul Patrick Serdula, 47, who worked in dental and medical offices across metro Atlanta, was arrested Monday night on child molestation and sodomy charges. The arrest came after authorities found several videos showing him fondling and groping patients who were under anesthesia at various offices, said Cobb County police officer Joe Hernandez.

Beauty Therapist convicted in Australia for doing tooth whitening

THE teeth-bleaching industry is in free-fall with many outlets forced to close after Victoria's dental and pharmacy boards warned that operators without dental training could be prosecuted.

The move comes after a Greensborough beauty therapist, Suong ''Becky'' Van Thi, was last month convicted and fined $2000 for being an unregistered person who performed ''invasive or irreversible'' procedures by whitening teeth in a beauty salon. MORE HERE 

Oral Bacteria May Trigger Multiple Sclerosis
Porphyromas gingivalis, a common oral bacterium in humans, produces a unique type of lipid, phosphorylated dihydroceramides (DHCs), which enhance inflammatory responses. These lipids are also likely produced by bacteria found in other parts of the body including the gastrointestinal tract. To determine if these lipids accentuate immune-mediated damage in autoimmune disease, researchers led by Robert B. Clark and Frank C. Nichols of the University of Connecticut Health Center administered phosphorylated DHCs in a mouse model of MS. The severity of disease was significantly enhanced by the addition of these lipids in a manner that was dependent on activation of the immune system. More HERE

Association of Periodontitis with Rheumatoid Arthritis
Journal of Periodontology,November 11, 2009.
In a cohort of U.S. veterans, periodontitis was more common and more severe in patients with rheumatoid arthritis compared to patients with osteoarthritis. Although unrelated to disease activity, the presence of periodontitis in RA patients was associated with seropositivity for both RF and anti-CCP antibody, highly relevant given the associations of these autoantibodies with poor outcomes and disease pathogenesis in RA.

Preventing H1N1 transmission in dental clinic
The Centers for Disease Control and Prevention (CDC) has released specific recommendations for dental healthcare professionals to prevent transmission of the 2009 H1N1 Influenza virus.

Viral transmission is thought to occur through droplet exposure of mucosal surfaces; through indirect contact, usually via the hands, with respiratory secretions from an infectious patient or contaminated surface; and through inhalation of small particle aerosols in the vicinity of the infectious individual.

The US authority encourages all dental healthcare personnel to receive seasonal influenza and 2009 H1N1 influenza vaccinations.  They should also continue to self-assess daily for symptoms of febrile respiratory illness (fever plus one or more of the following: nasal congestion/runny nose, sore throat, or cough), and not attend work until at least 24 hours after they are free of fever.

Tapered Rotary Systems Do not Clean apical third

Mesiobuccal canals of 60 molar teeth with angles of curvature between 25 and 35 degrees were prepared with a torque controlled low speed engine; 30 canals for each system. Each individual instrument was used to prepare four root canals and the time required for preparation was recorded. Standardized radiographs were taken before and following instrumentation and used to determine changes in canal curvature.

SEM analysis of the root canals showed no differences between groups. Clean dentine surfaces were seen in the coronal and middle thirds, but smear layer and debris remained in the apical third of the root canal with both systems. Only Complete system which cleans all parts of root is Smart Endo.  FULL PAPER

Do periodontopathogens disappear after full-mouth tooth extraction?
Journal of Clinical Periodontology,Volume 36 Issue 12, Pages 1043 - 1047

The elimination of subgingival niches, by extraction of all natural teeth, resulted in a 3-log reduction of Porphyromonas gingivalis and Tannerella forsythia, and more modest reductions of Aggregatibacter actinomycetemcomitans and Prevotella intermedia. However, the detection frequencies of these periodontopathogens in saliva and on the tongue remained unchanged after full-mouth tooth extraction.

Conclusion: In contrast to what has been believed so far, full-mouth tooth extraction does not result in eradication of all periodontopathogens but only in a significant reduction. The clinical consequences of this observation remain speculative.

Gum disease may reactivate HIV
Japanese study points to good oral health as a means to prevent spread of HIV

Good dental health may help prevent AIDS, say Japanese researchers.
The link, they say, could be periodontal, or gum, disease.

The researchers found that periodontitis-causing P. gingivalis bacteria can trigger a pathway that causes reactivation of latent HIV-1, the virus that causes AIDS. P. gingivalis is among the most widely existent bacteria worldwide.

The findings were presented April 3 in Miami at a meeting of the International & American Association for Dental Research. MORE

Dentist faces arrest for cheating judge

MUNGER, Bihar: A non-bailable warrant of arrest was slapped on a private dental surgeon on Tuesday for allegedly cheating an additional district and sessions judge here. Chief judicial magistrate Manoj Kumar Sinha issued the warrant after police said the dentist was evading arrest.

The then Munger additional district and sessions judge, Amarnath Sahay, had lodged an FIR at Kotwali police station in March this year against dental surgeon K K Sinha in this regard.

Sahay alleged that he had paid Rs 10,000 to Sinha, who had advised him that his painful teeth needed to be capped when he had visited his clinic located near Durgaasthan in the Barabazar locality. MORE HERE


Excessive Gingival Display—Etiology, Diagnosis, and Treatment Modalities
(Quintessence Int 2009;40:809–818) 

Extensive exposure of the gingiva during a smile, called excessive gingival display, may be a point of concern for both patients and clinicians. Patients often present to the dental clinic seeking a solution to their “gummy” appearance. A clinician must fully understand the various factors involved in this situation, to provide patients with an appropriate answer. Thorough examination followed by the right diagnosis is imperative for achieving an esthetic and predictable result in the treatment of such situations. The aim of this article is to discuss the various aspects of excessive gingival display and its etiology and to present the current solutions that exist in the literature. Download FULL paper

How to Deal with a fractured Ceramic restoration (PFM)

Q Occasionally I see patients with a piece of ceramic fractured from a porcelain–fused–to–metal (PFM) crown or bridge or a space between two PFM crowns. I have some questions about these frustrating problems. What commonly causes the fractures, and what can I do so the restorations will hold for a reasonable period of time? Additionally, can I fill a diastema that has developed between two PFM restorations?

A Numerous factors can cause fracture of a piece of ceramic from a PFM restoration. The fault may be caused by the patient, technician, or dentist.

Patient–caused fractures: The ceramic material fired or pressed onto the surface of a metal framework to make a PFM crown has known strength and measurable bond to the metal. If the patient accidentally places too much load on the restoration, it will fracture. The same phenomenon is present for natural teeth. A hard piece of candy or ice, a cherry seed, or a chicken bone can certainly break a piece of enamel away from the underlying dentin. The same forces will break a PFM restoration. FULL REPLY

Researchers have discovered that gum disease can affect the brain in elderly patients.

This can happen by causing inflammation throughout the body, a risk factor for loss of mental function.

The study, based on adults aged 60 and older found those with the highest levels of the gum disease-causing pathogen Porphyromonas gingivalis were three times more likely to have trouble recalling a three-word sequence after a period of time.

The study, led by Dr James Noble at Columbia College of Physicians and Surgeons in New York, also found that adults with the highest levels of this pathogen were two times more likely to fail three-digit reverse subtraction tests. MORE HERE

New Gel to remove tooth decay

A new product made from an Arequipean fruit locally known as "Papaya arequipeña," (Carica pubescens) that allows the removal of tooth decay without the use of mechanical methods, was officially presented by the Interdisciplinary Center for Research and Innovation (CICA) at Arequipa's Catholic University of Santa Maria (UCSM).

The developers of this gel, called Renova Caries, claim that it softens dental decay and allows an easy manual removal of it, without using dental drill nor anesthesia, which reduces the patients' anxiety. More

Amalgam or Composites ?

"A lot of people, for aesthetic reasons, are choosing to use the composite type of materials even for the back teeth," Miliano said. "There certainly is a gradual decrease as composite fillings get better and easier to use. They are more expensive, but are usually covered to some degree by insurance companies."

She said amalgam becomes a danger to the environment when it breaks down in the wastewater system from heat and pressure and becomes methylmercury. Detailed REPORT

Masking of labial enamel white spot lesions by resin infiltration—A clinical report
(Quintessence Int 2009;40:713–718)
This article describes a novel approach to treat smooth-surface white spot lesions micro-invasively. The technique is based on the infiltration of enamel caries lesions with low-viscosity light-curing resins called infiltrants. After the surface layer is eroded, the lesions are desiccated and a resin infiltrant is applied. The resin penetrates into the lesion micro-porosities driven by capillary forces and is subsequently hardened. Infiltrated lesions lose their whitish appearance and look similar to sound enamel. Additionally, the treatment prevents lesion progression. The proposed technique might be an alternative to microabrasion and restorative treatment, in particular for white spot lesions of esthetically relevant teeth.

Are you scaring your Orthodontic patient away with Separators
Separators can be painful. Assess patient s pain thresh hold, if patient is very sensitive then it is much better to bond the anteriors and put a light NiTi or even braided archwire. As patient slowly adapts then we can use bands, or bond buccal tubes (works very well specially on max molars). By follwing this easy tip you will find that your patient acceptance rate will go up.

Management of Partially Impacted Mandibular Second Molars with an Australian Uprighting Spring-
The Orthodontic CYBER Journal, 11/05/09

Doshi J et al. – Impaction of permanent teeth is a common clinical occurrence that may involve any tooth in the dental arch. The teeth most often impacted, in order of frequency, are the maxillary and mandibular third molars, the maxillary canines and the mandibular second molars. A typical case of bilateral partially impacted mandibular molars is illustrated, with uprighting spring as a treatment option and different treatment modalities for impacted molars are discussed.

Dentists Can Identify Patients At Risk For Fatal Cardiovascular Event.

JADA Nov 2009
A new study indicates dentists can play a potentially life-saving role in health care by identifying patients at risk of fatal heart attacks and referring them to physicians for further evaluation.

The participating dentists and their staff members used a computerized system, HeartScore (European Society of Cardiology, Sophia Antipolis, France), to calculate the risk, in percentages, of a patient’s dying as a result of a CVD event within the next 10 years. Dentists advised patients with HeartScores of 10 percent or higher to seek medical advice. After six to 12 months, one of the authors conducted structured telephone interviews to ascertain the results of the medical referrals.
Conclusions. Oral health care professionals can identify patients who are unaware of their risk of developing serious complications as a result of CVD and who are in need of medical intervention. The authors’ findings suggest the need for more studies with larger sample populations. More HERE

Low-level laser therapy for pain caused by placement of the first orthodontic archwire
American Journal of Orthodontics and Dentofacial Orthopedics, 11/10/09
The patients in the low–level laser therapy (LLLT)  group had lower mean scores for oral pain and intensity of pain on the most painful day. Also, their pain ended sooner. LLLT did not affect the start of pain perception or alter the most painful day. There was no significant difference in pain symptomatology in the maxillary or mandibular arches in an evaluated parameter.
Conclusions
Based on these findings, it was concluded that LLLT efficiently controls pain caused by the first archwire.

New Filling Material is Born
Kent Coulter and his colleagues at Southwest Research Institute in San Antonio have developed a new proof-of-concept dental restorative material under a program funded by the National Institutes of Health that seeks to replace amalgam with other materials. They will describe the material on November 9 at a meeting of the scientific society AVS in San Jose. The new fillings are made with a plastic-like material containing zirconia nanoplatelets -- tiny crystals made of the same sort of material used to make fake diamonds and gem stones. Unlike their costume jewelry cousins, the zirconia nanoplatelets super hard because of a difference in the particular arrangements of the atoms in the material.

Coulter and his colleagues designed a way to make a roll of this material under vacuum. They envision that this material would be lifted from the roll and packed in a dental cavity and then cured -- using an ultraviolet lamp or some other means -- so that it hardens in place without shrinking.

New Bracket Design gives better bond strength
EJO Nov 2009

The R-system® provided a bond strength greater than that of the mesh-base bracket. EDS showed that the amount of calcium on the novel base was higher than that on the conventional base, which allowed transfer of torsional stress more uniformly to the substrate, resulting in higher bond values for the R-system®. On the other hand, as debonding of the R-system® occurred at the enamel–composite interface, lesions to the enamel substrate are possible.

Lung Cancer Signs may appear early in Oral Mucosa

Future lung cancer prevention trials, for example, could soon be designed so that surface tissues inside the cheek could be checked to detect tobacco-induced damage in the lungs, according to a study led by Mao last year published in the journal Cancer Prevention Research.

"We hypothesized that tobacco-induced molecular alterations in the oral epithelium are similar to those in the lungs," says Mao. "This might have broader implications for using the mouth as a diagnostic indicator for general health."

Ethical issue of root breakage, Implant Surgery Video, Antibiotic cause Birth Defects

Ethical/ Legal issues after the root breakage during extraction of tooth

'Although the dentist was not unethical in breaking the roots and referring the patient to a hospital, we do feel however that the patient management and communication aspects of the case have much room for improvement.'

He added that for difficult extractions, for example, a badly broken tooth or a tooth with multiple or curved roots, it is not uncommon to fracture (break) the roots during extraction.

'Therefore breaking roots during extractions is not considered a 'mistake'. However, the most important thing is what the dentist does after the roots break,' said Dr Ang.

If the dentist is able to, she should try to take out the roots.

If she is unable to, she has an obligation to refer the patient to another colleague, to a hospital or a specialist surgeon to remove the broken roots. MORE HERE

Antibiotics can Cause Birth Defects
