New Device Could Shorten, Improve Orthodontic Treatment

A team of orthodontists at The University of Texas Health Science Center at San Antonio hopes to speed up and improve orthodontic treatment using a new device called the AcceleDent.

Dubravko Pavlin, D.M.D., M.S.D., Ph.D., an associate professor in the Department of Orthodontics at the Health Science Center, worked with a team of investigators from OrthoAccel Technologies, Inc. of Houston to help develop the device.

The study involves 34 patients ages 12 to 40 who need braces. Patients receive standard orthodontic treatment including any necessary extractions, and are fitted for braces at the Health Science Center Orthodontic Clinic. Once their braces are on, patients are provided with an AcceleDent device to use at home. The device, which stands about 4 inches high and features a wafer-thin mouthpiece attached to a small, sleek battery-operated handle, almost resembles a gizmo from a science fiction movie.

Patients are instructed to place the device in their mouth and bite down for 20 minutes a day during orthodontic treatment. While in the mouth, the device delivers a low-frequency pulsating vibration to the teeth. The researchers believe the vibratory forces, in combination with standard orthodontic treatment, will enhance the metabolism in bone tissue surrounding the teeth, thus allowing the teeth to move and straighten faster and more effectively.

Impact of Mobile phones on human parotid gland secretion
Oral Diseases, Published Online: 8 Sep 2009

This study evaluated whether mobile phone induces physiologic changes in the adjacent parotid gland, located on the dominant side, in terms of secretion rates and protein levels in the secreted saliva.
Materials and method: Stimulated parotid saliva was collected simultaneously from both glands in 50 healthy volunteers whose mobile use was on a dominant side of the head.

Results: A significantly higher saliva secretion rate was noticed in the dominant mobile side compared with that in the non-dominant side. Lower total protein concentration was obtained in the dominant compared with the non-dominant mobile side among the right dominant mobile users.
Conclusions: Parotid glands adjacent to handheld mobile in use respond by elevated salivary rates and decreased protein secretion reflecting the continuous insult to the glands.

Prevent Periodontitis To Reduce The Risk Of Head And Neck Cancer
Chronic periodontitis, a form of gum disease, is an independent risk factor for head and neck squamous cell carcinoma. This suggests the need for increased efforts to prevent and treat periodontitis as a possible means to reduce the risk of this form of cancer.
Results of this study are published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
Findings showed that chronic periodontitis might represent a clinical high-risk profile for head and neck squamous cell carcinoma. The strength of the association was greatest in the oral cavity, followed by the oropharynx and larynx, according to Dr Mine Tezal.
The study of poor oral health including the possible carcinogenic role of microorganisms is part of a rapidly growing interest in how a community of microbes that live in the various environments of the human body can affect health. Full News
