Dentin Hypersensitivity Treated With Diode Laser and Aminefluoride: A Randomized Clinical Trial.

Area of Science:

• Dentistry
• Biomedical Engineering
• Pain Management

Background:

• Dentin hypersensitivity (DH) is a common dental condition causing significant pain.
• Current treatments for DH include topical agents like amine fluoride (AF) gel.
• Novel therapeutic approaches are needed to enhance pain relief for DH.

Purpose of the Study:

• To evaluate the efficacy of amine fluoride (AF) gel with diode laser therapy versus AF gel alone in managing dentin hypersensitivity (DH).
• To compare the pain reduction outcomes between the two treatment groups over a 6-month period.

Main Methods:

• A split-mouth study design involving 43 patients (86 teeth) was employed.
• Teeth were treated with either 980 nm diode laser plus AF gel or AF gel alone.
• Pain was assessed using the Numerical Rating Scale (NRS) following thermal stimuli at baseline and at 1 week, 1, 3, and 6 months post-treatment.

Main Results:

• Both treatment groups showed a significant reduction in DH pain (p < 0.05).
• The diode laser combined with AF gel demonstrated significantly superior pain control over time compared to AF gel alone (p > 0.05).
• The combined therapy was more effective immediately after treatment and in the long term (p < 0.05).

Conclusions:

• Diode laser therapy in conjunction with AF gel provides enhanced pain reduction for dentin hypersensitivity.
• The combination therapy is a more effective treatment option for DH than AF gel alone.
• This approach offers significant benefits for long-term management of tooth sensitivity.
