Summary
The Aquafresh Between Teeth Buzz toothbrush demonstrated superior plaque removal efficacy in laboratory tests. This new vibrating toothbrush outperformed two leading oscillating-rotating models in interproximal cleaning.
Area of Science:
- Dental hygiene and oral care technology.
- Biomechanical assessment of toothbrush efficacy.
Background:
- A novel toothbrush featuring elongated fine bristles and a vibrating bristle field has been developed.
- Evaluating new oral hygiene products requires robust laboratory methods predictive of clinical outcomes.
Purpose of the Study:
- To compare the interproximal access efficacy (IAE) of the new toothbrush against two commercially available oscillating-rotating powered toothbrushes.
- To assess the simulated plaque removal capabilities of the new toothbrush in a laboratory setting.
Main Methods:
- The study employed an interproximal access efficacy (IAE) assay using artificial plaque on a pressure-sensitive substrate around simulated teeth.
- Brushing motions included horizontal and vertical techniques.
- Three toothbrushes were tested: Aquafresh Between Teeth Buzz, Oral-B Vitality Precision Clean, and Oral-B Professional Care 6000. Each was tested 24 times.
Main Results:
- The Aquafresh Between Teeth Buzz toothbrush showed statistically significant superiority (p < 0.05) over both Oral-B models in all conducted tests.
- Consistent and superior performance was observed for the new toothbrush in the IAE assay.
Conclusions:
- The new toothbrush demonstrated significantly higher overall efficacy in the IAE assay compared to the tested commercial powered toothbrushes.
- The laboratory IAE assay's predictability suggests the new toothbrush will effectively cleanse dental interproximal sites.

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
