福利姬视频

The 福利姬视频 recommends brushing teeth twice a day for two minutes using a fluoride toothpaste. Brushing for two minutes has been shown to achieve clinically significant plaque removal³ and use of a toothpaste containing fluoride enhances fluoride concentration levels in biofilm fluid and saliva, and is associated with decreased risk of caries and remineralization of teeth.⁴

There are a number of techniques for brushing teeth; any of which may have advantages depending on a patient’s particular needs.⁵ In general, the 福利姬视频 suggests that people place the toothbrush against the gumline at a 45-degree angle to remove plaque from above and just below the gingival margin, and move the toothbrush gently back and forth in short strokes.⁶ To clean the inside surfaces of the front teeth, they should tilt the brush vertically and make several up-and-down strokes. 

Regardless of the technique used, brushing should touch upon all surfaces—inner, outer and chewing. Also, when brushing, the 福利姬视频recommends that people use a soft-bristled toothbrush and apply gentle pressure, both of which may help reduce the risk of gingival injury.^{7, 8}

Here are some toothbrush care tips to share with your patients:

• Toothbrushes should not be shared.  Sharing a toothbrush could result in an exchange of bodily fluids and microorganisms between people.⁹
• Rinse the toothbrush thoroughly after each use to remove any remaining paste and debris.⁹
• Store toothbrushes in an upright position after use and allow them to air dry.  Storing a moist toothbrush in a closed container promotes microbial growth more so than leaving it exposed to the open air.¹⁰
• Toothbrushes should be replaced approximately every three to four months or more often if the bristles become matted or frayed.  The effectiveness of the brush decreases as the bristles become worn.¹¹

Toothbrushes have been shown to harbor bacteria (including fecal coliform bacteria that can be released into the air when the toilet is flushed or can be spread to the toothbrush when the owner touches a contaminated surface before handling his or her brush).¹²  While toothbrushes have been shown to harbor bacteria, there is no evidence that these bacteria cause adverse health effects.  Nonetheless, some patients may be interested in sanitizing their toothbrushes.  While there is little data in the literature regarding toothbrush sanitizing, one study indicates that soaking a toothbrush in 3 percent hydrogen peroxide or Listerine mouthwash greatly reduces (i.e., 85 percent) bacterial load.¹³  Microwaving or putting toothbrushes in the dishwasher is not recommended as such high heat may damage the brush.  Toothbrush sanitizer devices are available. Patients should look for a device that has been cleared by the U.S. Food and Drug Administration (FDA).

A myriad of toothbrush head design options are available.¹⁴ One systematic review found that toothbrushes with either multi-level bristles or angled bristles perform better than the conventional flat-trimmed bristles in removing plaque.¹⁵ Although toothbrushes with medium bristles have been shown to be effective at biofilm removal, the 福利姬视频recommends use of a toothbrush with soft bristles because they minimize the risk of gingival abrasion.⁸

The 福利姬视频Seal Category section on ADA.org provides a list of manual toothbrushes that currently have the 福利姬视频Seal of Acceptance. The Seal of Acceptance indicates that the toothbrush is both safe and efficacious for the removal of plaque and reduction of gingivitis. In addition, ANSI/福利姬视频standards are used for testing the safety of manual toothbrushes.¹⁶

If a toothbrush differs significantly from previously accepted toothbrushes, the Council may request clinical studies to demonstrate that the toothbrush could be used without supervision by an average adult to achieve a significant decrease in mild gum disease and plaque over a 30-day period.¹⁶

Both manual and powered toothbrushes are effective at removing plaque.^{15, 17} While the powered toothbrushes can be more expensive than most manual toothbrushes, some people prefer the powered version. People who have dexterity problems—like the elderly, people with disabilities, or children—or those who have dental appliances, like braces, may find a powered toothbrush easier to use.

The 福利姬视频Seal Category section on ADA.org provides a list of powered toothbrushes that currently have the 福利姬视频Seal of Acceptance. The Seal of Acceptance indicates that the toothbrush is both safe and efficacious for the removal of plaque and reduction of gingivitis. In addition, ANSI/福利姬视频standards are used for testing the safety of powered toothbrushes.¹⁸

A variety of powered toothbrushes that use a different types of head movement (e.g., side-to-side, counter oscillation, rotation oscillation, circular, ultrasonic) are available.

Look for the 福利姬视频Seal—your assurance that the product has been objectively evaluated for safety and efficacy by an independent body of scientific experts, the 福利姬视频Council on Scientific Affairs. The 福利姬视频Seal Category section on ADA.org provides a list of manual and powered toothbrushes that currently have the 福利姬视频Seal of Acceptance. A manual or powered toothbrush earns the 福利姬视频Seal for toothbrushes when the manufacturer provides scientific evidence demonstrating safety and efficacy in the removal of plaque and reduction of gingivitis. Toothbrushes with the 福利姬视频Seal have had data reviewed by the 福利姬视频Council on Scientific Affairs and have met the recommendations for both manual and powered toothbrushes.

ANSI/福利姬视频standards are used for testing the safety of manual¹⁶ toothbrushes. To qualify for the Seal of Acceptance, the manufacturer of a manual toothbrush must provide evidence that:

• All toothbrush components are safe for use in the mouth
• Bristles are free of sharp or jagged edges and endpoints
• Handle material demonstrates durability under normal use
• Bristles won’t fall out with normal use.
• The toothbrush can be used without supervision by the average adult to provide a significant decrease in mild gum disease and plaque

If a toothbrush differs significantly from previously accepted toothbrushes, the Council may request clinical studies to demonstrate that the toothbrush could be used without supervision by an average adult to achieve a significant decrease in mild gum disease and plaque over a 30-day period.

To earn the Seal, a powered toothbrush goes through tests based on the ANSI/福利姬视频standards for testing powered toothbrushes.¹⁸  These tests evaluate qualities like electrical safety, tuft retention, mechanical strength and chemical resistance.  The Seal program also requires powered toothbrushes to complete a clinical study demonstrating that they are safe for use on oral hard and soft tissues as well as restorations and that they meet the requirements of a safety laboratory such as Underwriters Laboratories, Inc.
