Desensitizing effects of Gluma and Gluma 2000 on hypersensitive dentin

Area of Science:

• Dentistry
• Dental Materials Science

Background:

• Dentin hypersensitivity is a common clinical condition.
• Erosion and abrasion lesions can expose dentin tubules, leading to sensitivity.

Purpose of the Study:

• To evaluate the efficacy of Gluma 3 Primer and Gluma 2000 conditioning solutions in managing dentin hypersensitivity.
• To compare the long-term effects of these agents on sensitive teeth with erosion/abrasion lesions.

Main Methods:

• A clinical trial involving 34 patients with severe dentin sensitivity.
• Topical application of Gluma 3 Primer (40 teeth) or Gluma 2000 (42 teeth), with 34 teeth as a control group.
• Sensitivity assessment via tactile and cold air stimuli at baseline, post-treatment, and at 1 week, 1 month, and 6 months.

Main Results:

• Both Gluma 3 Primer and Gluma 2000 groups demonstrated significant sensitivity reduction post-treatment and at 1 week (P < 0.05).
• No significant difference in sensitivity was observed between 1 week and 6 months in the Gluma groups.
• The control group showed no pain reduction up to 1 month, with only slight spontaneous reduction by 6 months.
• At 6 months, 29 Gluma-treated and 31 Gluma 2000-treated teeth were free of dentin sensitivity.

Conclusions:

• Gluma 3 Primer and Gluma 2000 are effective in reducing dentin hypersensitivity caused by erosion/abrasion lesions.
• The desensitizing effects of these agents are significant and sustained for at least 6 months.
• These conditioning solutions offer a viable treatment option for managing dental hypersensitivity.
