Ozone Therapy Demonstrates Superior Long-Term Relief for Dentin Hypersensitivity

A recent randomized clinical study has revealed that ozone gas treatment provides more sustained relief from dentin hypersensitivity (DHS) than diode laser therapy.

The study involved 44 patients with moderate DHS, encompassing 132 teeth, which were randomized into three groups using a split-mouth design:

• ozone gas treatment
• diode laser treatment
• placebo group receiving no therapy

In the ozone gas group, a high dose of ozone (32 g/m³) was applied for 30 seconds using a silicone cup. The diode laser group received irradiation of the exposed dentin with an 808-nm wavelength laser at incremental power levels ranging from 0.2 to 0.6 W, with 20-second intervals.

Dentin sensitivity was assessed at baseline, immediately after treatment, and at 3 and 6 months post-treatment using cold air blast and tactile stimuli. Pain severity was quantified using a visual analogue scale.

Both ozone gas and diode laser treatments resulted in a significant immediate decrease in DHS compared to the placebo group. However, after six months, the teeth treated with ozone gas maintained significantly lower sensitivity levels than those treated with diode lasers (P < .05). This indicates that while both treatments are effective initially, ozone therapy offers more enduring benefits for DHS management.

The findings suggest that ozone gas treatment may be a more advantageous option for long-term relief of dentin hypersensitivity, potentially improving patient comfort and reducing the need for repeated interventions over time.
