Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Clinical and radiographic success rate of two methods of caries removal. The outcome will be based on clinical and radiographic success rate, which will be evaluated as follows: Clinical success. - using modified USPHS criteria (United State Public Health Service) for clinical evaluation (6 to 24 months). This criterion clinically evaluates aspects of the restorations, as marginal discoloration, anatomical shape, marginal integrity and existence of caries lesions adjacent . results a and B considered successful and results C and D regarded as failure. The results will be presented in the form of prevalence. Radiographic success - if radiographically there is the suggestion of progression or not of carious lesion and the existence of any changes in furca region - between the roots - (6 to 24 months). These changes will be considered as failure. visually assessed criterion for blind evaluator.;In total, 35 teeth (19 that underwent TCR and 16 that underwent PCR) were followed up at year 2. At year 2, the success rates for each group were 89,47% and 93,75% for TCR and PCR, respectively (p > 0.05). | — |
Secondary
| Measure | Time frame |
|---|---|
| Main causes of restorative failure ;The cause of failure in the PCR group was a secondary caries lesion (1 teeth). In the TCR group, the causes of failure included restoration fracture (1 teeth) and increased radiolucency under the restorative material, suggesting progression of carious lesions (1 teeth). | — |
