Dental Caries
Conditions
Brief summary
The current study intends to evaluate the effect of cervical margin relocation with different restorative materials on three-year clinical performance of indirect Computer-Aided-Design (CAD)/ Computer-Aided-Manufacture (CAM) onlay restorations. This study is designed to test the null hypothesis that the three-year clinical performance of onlay restorations is significantly affected by cervical margin relocation with different restorative materials.
Interventions
different dental restorative materials used to relocate deep cervical margins before receiving onlay restorations

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Gingiva | three year follow up | Gingival Index Scale from 0 to 3 will be used for evaluation considering that score 0 represents normal gigiva while score 3 represents severely inflamed gingiva |
| Modified World Dental Federation (FDI) clinical Criteria | three year follow up | 1. Functional Properties of restorations: 1. Fracture of material and retention 2. Marginal adaptation 3. Radiographic examination 2. Biological Properties of restorations 1. Postoperative (hyper-sensitivity and tooth vitality 2. Recurrence of caries 3. Tooth integrity (enamel cracks, tooth fractures) 4. Periodontal Response 5. Adjacent mucosa Descriptive scale from 1 to 5. Note: 1 is clinically excellent 5 is clinically poor. Scores(1-3) are considered sufficient The overall cumulative success rate of restorations will be evaluated |
