Tooth Hypersensitivity

Outcome Measures

Primary Outcomes (6)

• Baseline Pre-Prophy Assessment (Tactile Sensitivity)

  Pre-prophy procedure baseline assessment is measured with an electronic force sensing probe (Yeaple probe). Grams of force needed to elicit pain are recorded as hypersensitivity score for the tooth. 10,20,30,40, up to 50 grams of force are applied to the hypersensitive tooth until pain is elicited. The higher the score (the more grams of force needed to elicit a response of pain), the lower the hypersensitiv Subjects were required to have two sensitive teeth which are not adjacent to each other and preferably in different quadrants. Scores were obtained by taking the average over the scores for the evaluated teeth.

  Pre-treatment measurement

• Immediate Sensitivity Relief (Tactile Sensitivity)

  Assessment of sensitivity score via tactile and air blast measurements immediately after treatment. Tactile hypersensitivity is measured with an electronic force sensing probel (Yeaple probe). Grams of force needed to elicit pain are recorded as hypersensitivity score for the tooth. Grams of force needed to elicit pain are recorded as hypersensitivity score for the tooth. 10, 20, 30, 40 up to 50 grams of force are applied to the hypersensitive tooth until pain is elicited. The higher the score (the more grams of force needed to elicit a response of pain), the lower the hypersensitivity. Subjects were required to have two sensitive teeth which are not adjacent to each other and preferably in different quadrants. Scores were obtained by taking the average over the scores for the evaluated teeth.

  Immediately after treatment .

• Long-term Sensitivity Relief (Tactile Sensitivity)

  Assessment of sensitivity score via tactile measurements long term after treatment. Tactile hypersensitivity is measured with an electronic force sensing probel (Yeaple probe). Grams of force needed to elicit pain are recorded as hypersensitivity score for the tooth. Grams of force needed to elicit pain are recorded as hypersensitivity score for the tooth. 10 to 50 grams of force are applied to the hypersensitive tooth until pain is elicited. The higher the score (the more grams of force needed to elicit a response of pain), the lower the hypersensitivity. Subjects were required to have two sensitive teeth which are not adjacent to each other and preferably in different quadrants. Scores were obtained by taking the average over the scores for the evaluated teeth.

  28 days (+/- 2 days) post treatment.

• Baseline Pre-Prophy Assessment (Air Blast Sensitivity)

  Pre-prophy procedure baseline assessment using Schiff Cold Air Sensitivity scale (0-3). Air blast hypersensitivity is measured using the Schiff Cold Air Sensitivty scale (0-3). The scale is scored as follows: 0=Subject does not respond to stimulus; 1= Subject responds to stimulus but does not request discontinuation of stimulus; 2=Subject responds to stimulus and requests discontinuation or moves from air stimulus; 3=Subject responds to stimulus, considers it painful and requests discontinuation. The higher the score, the higher the hypersensitivity. Subjects were required to have two sensitive teeth which are not adjacent to each other and preferably in different quadrants. Scores were obtained by taking the average over the scores for the evaluated teeth.

  Pre-treatment measurement

• Immediate Sensitivity Relief (Schiff Air Blast Sensitivity)

  Assessment of sensitivity score via air blast measurements immediately after treatment. Air blast hypersensitivity is measured using the Schiff Cold Air Sensitivity scale (0-3). The scale is scored as follows: 0=Subject does not respond to stimulus; 1= Subject responds to stimulus but does not request discontinuation of stimulus; 2=Subject responds to stimulus and requests discontinuation or moves from air stimulus; 3=Subject responds to stimulus, considers it painful and requests discontinuation. Subjects were required to have two sensitive teeth which are not adjacent to each other and preferably in different quadrants. Scores were obtained by taking the average over the scores for the evaluated teeth.

  Immediately after treatment .

• Long-term Sensitivity Relief (Schiff Air Blast Sensitivity)

  Assessment of sensitivity score Schiff air blast measurements long term after treatment. Air blast hypersensitivity is measured using the Schiff Cold Air Sensitivity scale (0-3). The scale is scored as follows: 0=Subject does not respond to stimulus; 1= Subject responds to stimulus but does not request discontinuation of stimulus; 2=Subject responds to stimulus and requests discontinuation or moves from air stimulus; 3=Subject responds to stimulus, considers it painful and requests discontinuation. Subjects were required to have two sensitive teeth which are not adjacent to each other and preferably in different quadrants. Scores were obtained by taking the average over the scores for the evaluated teeth.

  28 days (+/- 2 days) post treatment.
