A toothbrush impalement injury of the floor of mouth in autism child

Dental Traumatology — Thu, 02 Feb 2012 05:00:00 +0100

We report a case of a toothbrush impalement injury of the floor of the mouth in a child with autism. A 5‐year‐old boy with autism presented with an accidentally impaled toothbrush in the oral cavity. He was taken to the operation room and examined under general anesthesia. The handle of the toothbrush was cut off using rib scissors for mask ventilation, and intra‐oral intubation was performed. The toothbrush was located approximately 2.5 cm into the floor of the mouth. The toothbrush was removed uneventfully. Intravenous antibiotic therapy was instituted during hospitalization, and discharge from the hospital occurred 4 days after the operation. (Source: Dental Traumatology)

Judge blocks Medi-Cal rate cuts to providers

bizjournals.com Health Care:Physician Practices headlines — Wed, 01 Feb 2012 22:55:19 +0100

A federal judge has blocked California’s attempt to cut Medi-Cal rates to doctors, dentists, pharmacists and other Medi-Cal providers by 10 percent. U.S. District Court Judge Christina Snyder granted a preliminary injunction Tuesday that prohibits the state from implementing the cut, which is part of a budget fix adopted by the California Legislature last March. In twin rulings in December, the same judge tossed California’s 10 percent cuts in Medi-Cal fees to pharmacies and skilled nursing units inside hospitals...

Low burnout risk and high engagement levels among oral and maxillofacial surgeons

European Journal of Oral Sciences — Wed, 01 Feb 2012 05:00:00 +0100

Gorter RC, Jacobs BLTH, Allard RHB. Low burnout risk and high engagement levels among oral and maxillofacial surgeons.   Eur J Oral Sci 2012; 120: 69–74. © 2012 Eur J Oral SciLittle is known about the well‐being of oral and maxillofacial surgeons. The aim of this study was to measure the levels of burnout risk and the demanding work aspects of Dutch oral and maxillofacial surgeons, as well as the levels of positive work engagement and stimulating aspects of the work environment. The Maslach Burnout Inventory, Dutch version (UBOS), and inventories on positive engagement, work demands, and stimulating aspects of work, were sent to all 179 Dutch oral and maxillofacial surgeons currently in clinical practices. With a 70% response, UBOS mean scores on Emotional Exhaustion and D...

Influence of epigenetic modifications of the interleukin‐10 promoter on IL10 gene expression

European Journal of Oral Sciences — Wed, 01 Feb 2012 05:00:00 +0100

The objectives of this study were to analyze the effect of DNA methylation and histone modifications on IL10 gene expression, the differences in epigenetic modifications between GG and AA genotypes of the ‐1087 IL10 gene polymorphism, and the methylation pattern in the region close to the ‐1087 position. Using B cells obtained from subjects with GG and AA genotypes we demonstrated that treatment with histone deacetylase inhibitors and 5‐aza‐2‐deoxycytidine resulted in an increase in the production of IL10 mRNA. The chromatin immunoprecipitation assay revealed that stimulation with lipopolysaccharide resulted in a higher fold increase in the acetylation of histone H4 and in the methylation of histone H3 for GG genotype cells than for AA genotype cells. The increase in acetylation ...

Survivin gene promoter polymorphism ‐31G/C as a risk factor for keratocystic odontogenic tumor development

European Journal of Oral Sciences — Wed, 01 Feb 2012 05:00:00 +0100

Andric M, Nikolic N, Boskovic M, Milicic B, Skodric S, Basta Jovanovic G, Milasin J. Survivin gene promoter polymorphism ‐31G/C as a risk factor for keratocystic odontogenic tumor development. Eur J Oral Sci 2012; 120: 9–13. © 2012 Eur J Oral SciSeveral single nucleotide polymorphisms in survivin gene promoters, notably ‐31G/C, have been shown to modulate the expression and activity of the survivin protein. Consequently, the ‐31G/C polymorphism has been identified as a risk factor for the development of several types of tumors. The aim of this study was to investigate a possible association between the ‐31G/C polymorphism and the risk for keratocystic odontogenic tumor (KCOT) development. DNA from 52 biopsy specimens of KCOTs and from 82 buccal swabs of healthy individuals was...

Residual ridge resorption, lower denture stability and subjective complaints among edentulous individuals

Journal of Oral Rehabilitation — Wed, 01 Feb 2012 05:00:00 +0100

In conclusion, these results highlight the importance of denture maintenance treatment. As the extent of residual ridge resorption in the mandible was the most important factor that increased dissatisfaction with lower complete dentures, it is also important to inhibit the progression of resorption by preventing tooth loss or by using implant‐retained dentures.

Oral health attitudes and behaviours of final‐year dental students

European Journal of Dental Education — Wed, 01 Feb 2012 05:00:00 +0100

Conclusions: Final‐year dental students showed well established, favourable oral hygiene attitudes and behaviours, with evidence to suggest this knowledge was developed whilst in dental school. Despite many ceasing smoking, 5% still smoked. All dental students should receive training in motivational counselling and tobacco cessation to ensure this is included in patient care.

Paper Clips For Root Canals Lands Dentist In Jail

Health News from Medical News Today — Tue, 31 Jan 2012 22:00:00 +0100

When dentists do a root canal they are supposed to use steel posts, and definitely not paper clips. A dentist from Massachusetts has just received a 1-year prison sentence at the Bristol County House of Correction, for using paper clips for just such procedures - he had faced charges of assault and battery, as well as defrauding Medicaid to the tune of $130,000, and intimidating a witness. Dr. Michael Clair, according to prosecutors, in an effort to reduce costs, would use parts of paper clips for root canals. A number of patients developed a range of problems, including infections...

Maxillary rehabilitation of periodontally compromised patients with extensive one-piece fixed prostheses supported by natural teeth: a retrospective longitudinal study

Clinical Oral Investigations — Mon, 30 Jan 2012 16:05:27 +0100

Conclusions Restorative treatment with extensive one-piece FDPs resulted in long-term stability of the periodontal outcomes. Gingival conditions were shown to deteriorate mildly despite periodic recalls for SPT. An association between deterioration and compliance was observed, suggesting that periodic examinations are essential for maintaining oral hygiene and hence to the success of treatment. Clinical relevance Given a favorable distribution of potential abutment teeth, treatment with tooth-supported extensive FDPs is desirable even in patients with a history of periodontitis. Removable dentures would involve a number of shortcomings, including functional problems and severe degradation of oral ecology. Tooth-supported FDPs are capable of restoring fun...

Two-Arm Blood Pressure Checks May Spot "Silent" Risks

Health News from Medical News Today — Mon, 30 Jan 2012 10:00:00 +0100

A new study appears to support the idea that blood pressure checks should be done in both arms. Researchers at the University of Exeter Peninsula College of Medicine and Dentistry (PCMD) in the UK reviewed evidence covering differences in systolic blood pressure between arms and found it could be a useful way to spot elevated risk of vascular disease and even death in cases that might otherwise be "clinically silent".
