You may be eligible if
A premolar or first molar with an NCL and hypersensitivity of ≥3 as indicated by the subject on the Numeric Pain Assessment Scale (2008 NCCN) with standardized air blast stimulation with no other tooth exhibiting hypersensitivity (≥2 as indicated by the subject on the NPAS) in the same quadrant. If the patient has a tooth in more than one quadrant that meet these criteria then the quadrant selected will be that containing the tooth with the highest hypersensitivity reading. If the sensitivities are the same the quadrant with the lesion with the greatest depth would be selected. If the sensitivities and depth are the same the quadrant with the most convenient restorative access will be selected.
Teeth with NCL depth of at least 1 mm as measured by placing a periodontal probe (e.g.) into the deepest part of the cervical lesion
Teeth free of mesial, distal, or buccal restorations (to avoid confounding hypersensitivity)
Teeth with mobility of \<1 mm when manipulated between blunt instruments
Subject able to follow the study protocol and willing to return for all evaluation appointments
Subject able to comprehend and sign the written consent form
Subject 18 years of age or older
You may not be if
Subject who has a medical condition that could interfere with reliable pain reporting
Subject who is taking a medication that could interfere with reliable pain reporting
Subject who has taken an analgesic medication (narcotic, NSAID, acetaminophen, salicylic acid) within 24 hr pretreatment
Subject who is undergoing active orthodontic treatment
Subject with any of the following: a) Hypersensitive teeth with carious lesions; b) Hypersensitive teeth with buccal vertical cracks in enamel; c) Hypersensitive teeth with an irreversible pulpitis (pain lasting more than 5 sec after stimulation); d) Hypersensitive teeth with full crowns; e) Hypersensitive teeth with partial denture clasps on the facial surface; f) Evidence of inflamed gingival tissue and bleeding on probing in the sextant being considered for treatment as part of the study (the etiology of these lesion is closely related to excessive or improper brushing perhaps with an abrasive dentifrice and there is almost never accumulated plaque associated with the NCL)
