What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Sensitivity Relief (Self-Assessment)	All subjects completed a questionnaire titled "How sensitive are your teeth?" to assess their whole-mouth tooth sensitivity prior to the baseline assessments. The questionnaire contained a 4-item verbal descriptor scale as follows: Score 0= no discomfort or awareness of sensitivity; 1=mild discomfort/pain from sensitive teeth; 2=moderate discomfort/pain from sensitive teeth; 3=severe pain from sensitive teeth. 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
Post- Scaling Sensitivity Relief (Self-Assessment)	All subjects completed a questionnaire titled "How sensitive are your teeth?" to assess their whole-mouth tooth sensitivity immediately following the scaling procedure. The questionnaire contained a 4-item verbal descriptor scale as follows: Score 0= no discomfort or awareness of sensitivity; 1=mild discomfort/pain from sensitive teeth; 2=moderate discomfort/pain from sensitive teeth; 3=severe pain from sensitive teeth. 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.	Post-scaling procedure,immediate
Post-prophylaxis Sensitivity Relief (Self-Assessment)	All subjects completed a questionnaire titled "How sensitive are your teeth?" to assess their whole-mouth tooth sensitivity immediately following the timed, 1-minute prophylaxis paste application. The questionnaire contained a 4-item verbal descriptor scale as follows: Score 0= no discomfort or awareness of sensitivity; 1=mild discomfort/pain from sensitive teeth;2=moderate discomfort/pain from sensitive teeth; 3=severe pain from sensitive teeth. 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.	Immediately following post-prophylaxis treatment.
Long-term Sensitivity Relief (Self-Assessment)	All subjects completed a questionnaire titled "How sensitive are your teeth?" to assess their whole-mouth tooth sensitivity 28 days following prophylaxis treatment. The questionnaire contained a 4-item verbal descriptor scale as follows: Score 0= no discomfort or awareness of sensitivity;1=mild discomfort/pain from sensitive teeth; 2=moderate discomfort/pain from sensitive teeth; 3=severe pain from sensitive teeth. 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.	28 days post-prophylaxis treatment.
