Diode Laser and Gas Ozone equally effective for treatment of Dentin Hypersensitivity

In a groundbreaking exploration, a recent study has delved into the realm of dentin hypersensitivity (DHS), evaluating the clinical efficacy of two innovative treatments – diode laser and gas ozone. This research, aimed at enhancing our understanding of effective DHS management, brings forth promising results that could reshape dental care practices. The study concluded that Diode laser and gas ozone demonstrated efficacy in treating dentin hypersensitivity with ozone maintaining consistent effectiveness even after 6 months.

The study results were published in the Journal of Endodontics.

The study, conducted on 44 patients with 132 teeth exhibiting moderate DHS, employed a split-mouth design to randomize the teeth into three groups. The diode laser group received targeted irradiation using an 808-wavelength diode laser with an incremental power from 0,2 to 0,6 W, with 20 seconds of interval, while the gas ozone group underwent a high-dose ozone application via a silicon cup. The placebo group, serving as a control, received no therapeutic intervention. Dentin sensitivity was meticulously assessed at various intervals – immediately post-treatment, after 3 months, and after 6 months – using cold air blast challenges and tactile stimuli. Pain severity was quantified through the Visual Analogue Scale (VAS).

Results:

• Excitingly, both the diode laser and gas ozone groups displayed a noteworthy reduction in DHS levels immediately after treatment, and this positive trend persisted at the 3-month and 6-month marks.
• Of particular interest is the longevity of the gas ozone's effectiveness, with sensitivity values remaining statistically lower than those treated with diode lasers after 6 months (p < 0.05).
• The study's findings bear significant implications for dental practitioners and patients alike.
• Diode lasers and gas ozone emerge as effective therapeutic options for addressing dentin hypersensitivity, offering hope for those grappling with this common dental woe.
• Furthermore, the sustained efficacy of gas ozone presents an intriguing avenue for long-term DHS management.

In conclusion, this comprehensive study underscores the promising efficacy of diode laser and gas ozone in combating dentin hypersensitivity. The sustained impact of gas ozone, even six months post-treatment, introduces an exciting dimension to dental care practices. As the dental community embraces these advancements, patients can look forward to more effective and lasting solutions for dentin hypersensitivity, marking a transformative chapter in oral health care.
