Summary
Stannous fluoride (SnF2) offers effective pain relief for dentinal hypersensitivity. A combination of in-office 0.717% fluoride solution for immediate relief and at-home 0.4% SnF2 gel for long-term management is recommended.
Area of Science:
- Dentistry
- Dental Pharmacology
- Pain Management
Background:
- Exposed dentine causes pain, with various agents showing limited effectiveness.
- Stannous fluoride (SnF2) has demonstrated promising results in managing dentinal hypersensitivity pain.
Purpose of the Study:
- To review and summarize clinical literature on the effectiveness of SnF2 solutions/gels for dentinal hypersensitivity.
- To statistically re-evaluate studies and provide recommendations for optimal SnF2 use.
Main Methods:
- Review of seven blinded clinical studies comparing SnF2 formulations to placebos.
- Statistical power analysis and meta-analysis to assess efficacy.
Main Results:
- 0.717% fluoride solution provided immediate, long-lasting relief (months) when applied for 3-5 minutes.
- 0.4% SnF2 gel showed a more gradual effect, requiring 2-4 weeks of continuous use.
Conclusions:
- An effective strategy combines in-office 0.717% fluoride solution for immediate relief and at-home 0.4% SnF2 gel for sustained effect.
- 0.717% fluoride solution can be used for occasional symptomatic relief during the initial treatment period.

01:23Local Anesthetics: Mechanism of Action
Local anesthetics (LAs) block sensory and motor impulses by inhibiting the sodium channels on the nerve cell membranes. This induces temporary loss of sensation, relieving pain in a specific body area.
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...

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.
