Conditions
Interventions
Six individuals will be selected with four teeth moderately to severely hypersensitive. In each individual, sensitive teeth will be randomly distributed into the following treatment groups: group 1 (
group 2 (6 teeth) - use of KNO3NaF and immediate restoration with composite resin Filtek Z250 (FZ250)
group 3 ( 6 teeth) – use of KNO3NaF once a week until remission of pain and restoration with FZ250
group 4 ( 6 teeth) - restoration with FZ250. The assessment periods will 0, 7, 30, 90 and 180 days

Inclusion criteria
Inclusion criteria: The volunteers: they will be included with age 18 years or older, enrolled in the clinics of dentistry UFPI having at least 20 dental elements. Non-carious lesions: at least four lesions whose sensitivity is classified by the patient for moderate to severe after administration of a air, and tooth wear between 2 and 4. These teeth must have an antagonist tooth.
Exclusion criteria
Exclusion criteria: The patient: will be excluded people who have made periodontal treatment and/or hypersensitivity treatment in the last six months, patients with bruxism in the active phase. Non-carious lesions: teeth with very deep lesions, when a ruber dam isolation is not possible and those that have been previously restored.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected that one of the interventions is more effective in controlling dentinal hypersensitivity not carious lesions. The outcome will be assessed by analyzing the presence of pain induce by an air jet against the site where the intervention was carried out. | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected that all interventions are effective up to 6 months of intervention. | — |
