Trial Summary

What is the purpose of this trial?

The purpose of this study is to evaluate the efficacy and safety of KH001 in subjects with dentin hypersensitivity.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment KH001 for tooth sensitivity?

Research shows that treatments containing potassium compounds, like potassium chloride and potassium nitrate, are effective in reducing tooth sensitivity. These compounds are similar to those used in KH001, suggesting it may also help alleviate tooth sensitivity. ^{1 2 3 4 5}

Is KH001 safe for human use?

The studies on similar potassium-based treatments for tooth sensitivity, like potassium chloride and potassium nitrate, show they are generally safe for use in humans, with no harmful effects on oral tissues. ^{6 7 8 9 10}

How does the drug KH001 for tooth sensitivity differ from other treatments?

KH001 is unique because it may involve components like calcium hydroxide, which has been shown to be more consistently effective in reducing tooth sensitivity compared to other agents like potassium nitrate. This suggests that KH001 could offer a more reliable reduction in sensitivity to various stimuli, such as hot, cold, and mechanical irritation. ^{11 12 13 14 15}

Findings from Research

A systematic review of 8 trials involving 234 patients found that laser therapy for dentin hypersensitivity may offer a slight clinical advantage over topical desensitizing agents, although results were conflicting among studies.

The application of lasers was generally safe, with no reported adverse effects such as pulpal damage or allergic reactions, suggesting that laser treatment can be a viable option for managing tooth sensitivity.

Laser therapy may be better than topical desensitizing agents for treating dentin hypersensitivity. Blatz, MB.[2012]

In a study of 45 patients with dentinal hypersensitivity, both low-level laser therapy (LLLT) alone and LLLT combined with 5% potassium nitrate (KNO3) toothpaste significantly reduced sensitivity more effectively than using KNO3 toothpaste alone over a 3-week period.

The results indicated that LLLT alone provided better relief from hypersensitivity after just one week compared to the combination treatment, suggesting that using toothpaste with LLLT does not offer additional benefits.

Treatment with gaseous ozone significantly reduced pain in hypersensitive teeth by 55% immediately after application, based on a study involving 31 subjects over 54 weeks.

While the pain levels decreased significantly in both the treated and control teeth over time, there was no significant difference in pain reduction between the test and control teeth, suggesting that the long-term benefits of ozone treatment may not be superior to natural healing.

In a 12-week study involving 41 subjects, the dentifrice containing potassium chloride and sodium monofluorophosphate significantly reduced dentinal hypersensitivity compared to a placebo, with noticeable effects within just 4 weeks.

The KCl/MFP dentifrice not only alleviated sensitivity but also led to significant plaque reduction by week 8, indicating additional oral health benefits.

In a study involving 171 dentists and 1862 patients with dentinal hypersensitivity (DH), about 60% of patients reported a reduction in pain after receiving various treatments, indicating that community-based dental practices can effectively manage DH.

Patients who experienced pain relief from treatments such as glutaraldehyde/HEMA compounds, oxalates, and bonding agents also reported high satisfaction with their care, highlighting the importance of patient-centered outcomes in evaluating treatment effectiveness.

The experimental dentifrice containing 3.75% potassium chloride (KCl) significantly reduced dentin hypersensitivity (DH) more effectively than the standard fluoride dentifrice over an eight-week period, as measured by the Schiff sensitivity score.

Both dentifrices were well tolerated, but the reference fluoride dentifrice showed a greater increase in tactile threshold after eight weeks, indicating some differences in how each product affects sensitivity, despite both being effective.

A clinical trial involving 67 subjects demonstrated that toothpaste containing 5.53% potassium citrate significantly reduced dentine hypersensitivity compared to a control toothpaste over an 8-week period.

The test group using potassium citrate toothpaste reported a greater reduction in sensitivity to cold air and overall self-perceived sensitivity than the control group, with statistically significant results at both 4 and 8 weeks.

The novel varnish containing potassium chloride and fluoridated hydroxyapatite effectively occluded dentinal tubules and significantly reduced dentin permeability compared to commercial fluoride varnish, making it a promising treatment for dentin hypersensitivity.

The varnish demonstrated biocompatibility with gingival and pulpal fibroblasts, indicating it is safe for use in dental applications without causing cytotoxic effects.

A randomized controlled trial with 63 participants showed that a dentifrice containing 5% potassium nitrate significantly reduced dental hypersensitivity over a 4-week period, as measured by a pain scale.

After 4 weeks, the potassium nitrate dentifrice group reported a greater reduction in pain compared to the fluoride dentifrice group, indicating its superior efficacy for this condition.

Calcium hydroxide was found to be more effective than potassium nitrate and the control in reducing sensitivity of hypersensitive root surfaces, showing significant results immediately and after 3 months.

The study suggests that calcium hydroxide could be a useful desensitizing agent following periodontal surgery to help manage pain and facilitate better oral hygiene.

In a study involving 24 periodontal patients, the application of saturated potassium nitrate (KNO3) significantly reduced dentinal hypersensitivity, with a p-value of less than 0.0001 indicating strong statistical significance.

The treatment was assessed using a visual analogue scale, comparing pain levels before and after KNO3 application across 36 regions involving 98 teeth, demonstrating its efficacy in relieving pain associated with exposed dentin.

In a clinical study with 62 participants over 8 weeks, a dentifrice containing potassium chloride (KCl) significantly reduced dentin hypersensitivity compared to a placebo, showing effectiveness as early as 4 weeks.

The combination of KCl with sodium monofluorphosphate (MFP) was also effective, and both formulations led to significant improvements in patient comfort and reduced plaque levels by the end of the study.

In a study involving 48 subjects over eight weeks, a dentifrice containing 5.0% potassium nitrate significantly reduced dentinal hypersensitivity compared to a placebo, with improvements noted in both tactile and thermal sensitivity after just four weeks (p < 0.0001).

The effectiveness of the potassium nitrate dentifrice continued to show significant improvements at the eight-week mark, confirming its clinical efficacy in managing dentinal hypersensitivity.

In a study involving 36 patients, both calcium hydroxide suspension and glutaraldehyde-based dentine primer effectively reduced tooth sensitivity after full crown preparation, with significant decreases in sensitivity observed over time.

No significant differences in efficacy were found between the two desensitizers, suggesting that both can be used interchangeably to manage sensitivity during dental procedures.
