Most dangerous airport,No Quality ortho without Mini implants ?

Tourists warned of Thailand airport scam, BBC news

We were questioned in separate rooms," Mr Ingram said. "We felt really intimidated. They went through our bags and demanded that we tell them where the wallet was."
The two were then put in what Mr Ingram describes as a "hot, humid, smelly cell with graffiti and blood on the walls".
Mr Ingram managed to phone a Foreign Office helpline he found in a travel guide, and was told someone in the Bangkok embassy would try to help them. Full Story

Comparison of the differences in cephalometric parameters after active orthodontic treatment applying mini-screw implants or transpalatal arches in adult patients with bialveolar dental protrusion -Journal of Oral RehabilitationPublished Online: 9 Jul 2009

The purpose of this study was to compare the differences in cephalometric parameters after active orthodontic treatment applying mini-screw implants (G1) or transpalatal arches (G2) as anchorage in adult patients with bialveolar dental protrusion needing extraction of four premolars. A total of 34 Chinese patients (18–33 years) with bialveolar dental protrusion were randomly assigned to G1 and G2.

Sliding mechanics and en-masse retraction of anterior teeth were applied to close extraction spaces. The changes in skeletal, dental and soft tissues were analyzed in both groups on lateral cephalograms before and after active orthodontic treatment. Independent samples and paired-samples t-tests were utilized to analyze the morphological changes in both groups. ANB angle was decreased in G1 and remained unchanged in G2 (P <> 0·05), there existed molars distalization in some patients. However, the maxillary molars in G2 were mesialized (P < style="font-weight: bold;">routinely recommended in patients with bialveolar dental protrusion.

Stopping Harmful Oral Bacteria

Yiping Han, associate professor at the Case Western Reserve University School of Dental Medicine, aims to understand how to build roadblocks for a common bacterium that's harmless in a mother's mouth but can turn deadly when it reaches an unborn child. She has received a five-year, $1.85 million grant from the National Institute of Dental and Craniofacial Research (NIDCR) at the National Institutes of Health to fund the effort.

According to Han this research into the mechanisms of bacterial transport not only has potential to prevent preterm and stillborn births, it may have implications in preventing periodontal disease. Periodontal disease has been linked to such health problem as arthritis, diabetes and heart disease. Full report

Periodontal health, oral health behaviours, and chronic obstructive pulmonary disease
Journal of Clinical Periodontology, Published Online: 14 Jul 2009

Aim: To evaluate the associations of periodontal health status and oral health behaviours with chronic obstructive pulmonary disease (COPD).

Materials and Methods: We conducted a case–control study of 306 COPD patients and 328 controls with normal pulmonary function. Their periodontal status and respiratory function were clinically examined and information on oral health behaviours was obtained using a validated questionnaire.

Results: Patients with COPD had fewer teeth and a higher plaque index than the controls. Univariate analysis showed that tooth brushing times and method, experience of dental floss use, dental visit and regular supra-gingival scaling, and oral health knowledge were significantly related to the risk of COPD. After adjusting for age, sex, and body mass index and stratifying by smoking status, inappropriate tooth brushing method (p=0.025 among non-smokers), lower regular supra-gingival scaling (p=0.027 among non-smokers and p<0.0001 p="0.019" p="0.044" style="font-weight: bold;">Conclusions: Poor periodontal health, dental care, and oral health knowledge were significantly associated with an increased risk of COPD. Our findings indicate the importance of promoting dental care and oral health knowledge that can be integrated into the prevention and treatment of COPD.

NEW Wonder Tooth Gel: Aloe Vera Gel benefits teeth and gums

ScienceDaily (July 17, 2009) — The aloe vera plant has a long history of healing power. Its ability to heal burns and cuts and soothe pain has been documented as far back as the 10th century. Legend has it that Cleopatra used aloe vera to keep her skin soft. The modern use of aloe vera was first recognized the 1930s to heal radiation burns. Since then, it has been a common ingredient in ointments that heal sunburn, minor cuts, skin irritation, and many other ailments. Buy Gum Correct- the best gum paint, email to icdr@hotmail.com

Texas Dental board More Lax and Lenient
The Austin American-Statesman reported Monday that the dental board is awaiting the results of a state auditor's review this month. The board, which has been dogged for years by critical audits and complaints of lax oversight, regulates 15,950 dentists, more than 33,000 hygienists and registered assistants, and 1,083 laboratories.

Association between periodontitis and Acute Myo Infarction confirmed
Journal of Periodontology-Posted online on July 16, 2009.

Background: The aim of the study was to evaluate the impact of clinical periodontal parameters and the presence of periodontal pathogens in patients with acute myocardial infarction (AMI).

Methods: A total of 104 subjects (54 patients with AMI and 50 healthy controls) were included. Subgingival plaque samples were analyzed for periodontal pathogens Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf) and Prevotella intermedia (Pi) using dot blot hybridization.

Results: AMI patients had a significantly higher frequency of probing depths (PD) of ≥4 mm than controls (39.2% vs. 14.9%, P <0.0001). p =" 0.0005)." p =" 0.0005)" p =" 0.0018)" style="font-weight: bold;">Conclusion: The results of our study confirm an association between periodontitis and AMI, in which periodontal destruction was correlated with the presence of periodontal pathogens. In particular, Pg might be considered as potential risk indicator for AMI.

Detection of root resorption using dentin and bone markers
Orthodontics & Craniofacial Research-Volume 12 Issue 3, Pages 229 - 235

with mild (<2>2 mm) were identified. Control group subjects with no loss of root structure or undergoing orthodontic treatment were also identified. Gingival crevicular fluid (GCF) was collected non-invasively from the mesial and distal sides of each of the four upper incisors by using filter paper strips. The eluted GCF was used for analysis using western blot and enzyme-linked immunosorbent assay (ELISA) techniques. Antibodies used were against osteopontin (OPN), (osteoprotegerin) OPG, and receptor activator of nuclear factor kappa B ligand (RANKL).

Results – Western blot analysis showed differential expression of OPN, OPG, and RANKL in the control and root resorbed subjects. However, processed forms of these proteins were only observed in the root resorbed subjects. Results from ELISA with OPG antibodies revealed a difference in OPG concentration between the control and root resorption groups. ELISA results with RANKL antibodies did show a statistically significant difference between the control group and the two study groups. The ratio RANKL/OPG was statistically higher in subjects with severe root resorption than in the control subjects.

Conclusions – Preliminary results confirm the presence of matrix proteins and cytokines in the GCF of root resorbed subjects. Further, OPG was locally present in excess amounts over RANKL and an increased RANKL/OPG in the study groups could be correlated with an increased bone resorption activity during orthodontic tooth movement.

Oral health linked to Alzheimer's risk
A study of Swedish twins shows several factors that increase risk for demetia. A new study of dementia led by USC researchers revealed that missing teeth and chronic inflammation of the mouth at an early age quadruples the risk of developing Alzheimer's disease.

The study, which was presented at the first Alzheimer's Association International Conference on Prevention of Dementia last week, examined the histories of over a hundred pairs of identical twins. Each pair consisted of one twin who had developed dementia, and one who had not. Acting on the premise that identical twins share an identical genetic blueprint, the study looked into external factors that could have led to the mental demise of the demented twin. More
