Teeth Sensitivity
Conditions
Brief summary
The aim of this study is to evaluate tooth sensitivity and marginal adaptation of porcelain laminates veneers prepared with modified gull wing preparation and conventional preparation.
Detailed description
Visit 1: Preoperative records, face-to-face adherence reminder session, clinical, radio-graphic examination and primary impression for diagnostic cast construction. Visit 2: Teeth preparation, secondary impression,temporary restoration and teeth sensitivity evaluation using United States Public Health Service criteria. Visit 3: Placement and permanent cementation of the final restoration Visit 4: marginal adaptation measurement by electron microscope using impression replica.
Interventions
PROCEDUREgull wing preparation of laminates veneers
preparation involving mesial and distal extension further lingualy.
PROCEDUREconventional preparation of laminates veneers
preparation not involving mesial and distal extension further lingualy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| measuring marginal adaptation of laminates veneers using stero-microscope | immediately before laminates delivery up to 4 week sfter tooth preparation | marginal adaptation of laminates veneers will be assess as follows, before laminates cementation, an impression material will be placed in the fitting surface of the veneers and placed over the reduced tooth using finger pressure, after material set the impression replica is separated from the laminates and the replica is section and measures under stero-microscope for marginal adaptation, measurement will be performed in eight different points on the buccal and mesio-distal sections, measurement will be in micrometer. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| measuring tooth sensitivity after tooth preparation for laminates veneers | one week after tooth preparation | measurment will be acording tomodified United States Public Health Service (USPHS) criteria used for the clinical evaluations of the restorations. post-operative sensitivity 0 No symptoms 1. Slight sensitivity 2. Moderate sensitivity 3. Severe pain |
