The Effects of Mouthguard and Desensitizing Toothpaste in Reducing Dental Hypersensitivity

Not Applicable

Completed

• Conditions: Dentine Hypersensitivity; Tooth Erosion
• Interventions: Device: mouthguard; Device: mouthguard with desensitizing toothpaste

• Registration Number: NCT03515902
• Lead Sponsor: Khon Kaen University

Brief Summary

Tooth hypersensitivity due to dental erosion is one of the most common problem related to swimming in improper pH chlorinated pools. Because the teeth are exposed to acidic water for a long time, which cause the loss of dental hard tissue. Tooth hypersensitivity can lead to a negative effect on daily life such as dietary selection, maintaining optimal dental hygiene and beauty aspects. It has been found that using mouthguard while swimming can prevent the teeth directly contact to chlorinated water, so it can protect tooth structure and decrease tooth hypersensitivity. Moreover, using mouthguard with viscous products can seal the gaps between mouthguard and teeth which can help to protect tooth structure and decrease dental hypersensitivity more effectively. At present, there are many desensitizing products such as toothpaste, mouthwash and chewing gum. Desensitizing toothpaste is the most common over-the-counter (OTC) materials in desensitizing. Many research has endorsed the properties of desensitizing toothpaste that can reduce tooth tissue loss and helps to reduce tooth hypersensitivity effectively. So it can be hypothesize that when use the combination of mouthguard with desensitizing toothpaste, it might have synergistic effect on reducing tooth hypersensitivity in swimmers.

Detailed Description

Tooth erosion is the loss of dental hard tissue due to acidic agents without bacteria involvement.

Mouthguard is a protective appliance use for covering the teeth and gums to prevent the teeth from acidic chlorinated water.

Desensitizing toothpaste is toothpaste containing 8 percent arginine and calcium carbonate that can reduce tooth demineralization and promote remineralization.

Primary Outcome Measures

Name	Time	Method
Tooth hypersensitivity changes after using mouthguard with/without desensitizing toothpaste	baseline,2,4 and 8 weeks	* Tooth hypersensitivity changes will be measured by the mean difference of visual analog scale (VAS) score at baseline,2,4 and 8 weeks by using 2 clinical stimuli including tactile and cold stimulation. Each stimulation will be measured and separately recorded as follow : 1.Tactile stimulation; * The score range from 0 (no tooth hypersensitivity) to 100 (worst possibly tooth hypersensitivity); * The mean difference of tooth hypersensitivity from tactile stimulation at any time point will be analyzed.; 2. Cold stimulation; * The score range from 0 (no tooth hypersensitivity) to 100 (worst possibly tooth hypersensitivity); * The mean difference of tooth hypersensitivity from cold stimulation at any time point will be analyzed.

Secondary Outcome Measures

Name	Time	Method
The attitude and satisfaction of using mouthguard with/without desensitizing toothpaste	2,4 and 8 weeks	* The attitude and satisfaction will be collected by a self-administered questionnaire and interview at 2,4 and 8 weeks; * The score range from 0 (no satisfying) to 100 (most satisfying); * The mean score of satisfying at any time point will be analyzed.
