About this study
Official title: CARies DEtection in Children 03 - The Impact of Two Different Clinical Criteria for the Evaluation of Caries Lesions Around Restorations in Primary Teeth
There is still great divergence in the aspects related to caries lesions around restorations. The methods and the systems used for the detection of secondary caries lesions have presented low validity. Also, the consequent treatment decisions of this kind of lesions have presented a lot of variation. However, the correct diagnosis of secondary caries may guarantee greater longevity to the restorative treatment, as well as oral health to the patients, reducing the cost and clinical time of the dentists. Therefore, the investigators aimed to perform this study to evaluate and compare two visual criteria for the evaluation of restorations in primary teeth in medium and long term outcomes for the patients, through a randomized clinical study. These criteria are the system proposed by the World Dental Federation (FDI) and the International Caries Classification and Management System - ICCMS.
Read the detailed description
Among the available diagnosis criteria to detect caries lesions around restorations, there are the World Dental Federation (FDI) criteria and the International Caries Classification and Management System - ICCMS. However, few studies have evaluated the accuracy of both methods. The impact of the use of these methods in the treatment decisions regarding the restorations was also not evaluated. In relation to the detection of caries lesions around restorations in primary teeth, no randomized clinical study was performed, so the aim of this study is to establish the best diagnosis and treatment decision to caries around restorations in children. For this, three different studies will be carried out according the following specific aims: (1) to evaluate the accuracy of the FDI criteria and the system proposed by the ICCMS for the evaluation of caries lesions around restorations in primary teeth through a cross-sectional study design; (2) to evaluate the impact and cost of using these two criteria in treatment decisions related to the evaluation of restorations in primary teeth through a cross-sectional study design; (3) to evaluate the influence of the use of these two criteria for the evaluation of restorations in primary teeth in medium and long term outcomes for the patients, through a randomized clinical trial. To reach these objectives 626 restorations will be evaluated in children from 3 to 10 years who have looked for dental treatment in our dental school. They will be randomly allocated in two groups according to the diagnostic strategy used for caries detection around restorations: diagnosis and treatment decision based on the criteria of the International Dental Federation (FDI) (control group) or diagnosis and treatment decision based on the CARS detection criteria and treatment decision proposed by the ICCMS (experimental group). The consequent treatment decision of the restorations will be divided into no restorative intervention; repair or replacement of the restorations. Children will be treated by dentists, blinded to the criteria used to reach the treatment decision and then, will be monitored for two years. Reassessments will be performed by a blind examiner in relation to the child's allocation group, and the occurrence of outcomes will be assessed according to predefined criteria described for evaluation of restorations performed in the context of atraumatic restorative treatment. The primary outcome will be the need for restorative intervention during the follow-up of the restorations evaluated by the different criteria. This outcome is composed of several components. The reference standard will be the presence of caries lesion adjacent to the restoration after removal of the restoration, and their occurrence will be compared among the methods by survival analysis.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Dental treatmentProcedure or surgery
Treatment of all dental restorations of the children according to the diagnosis criteria
| Study group | Role | What they receive |
|---|---|---|
| International Dental Federation | Experimental | Dental Treatment: according to the decision based on the International Dental Federation (FDI) criteria Receives: Procedure: Dental treatment |
| Caries Around Restorations System | Experimental | Dental Treatment: according to the decision based on the Caries Around Restorations System (CARS) and treatment decision proposed by the International Caries Classification and Management System (ICCMS) Receives: Procedure: Dental treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Restoration survival
Major failures of restorations: restorations presenting failures that need replacement or teeth with pulp involvement, pain or that need extraction (except due to orthodontic reasons). For restorations involving occlusal surfaces, score 4 of Frencken et al. criteria (1996) will be considered. For restorations involving other surfaces, the scores 21, 30, and 40.
The primary outcome was changed due to the COVID-19 pandemic situation. As we were not able to assess patients' restorations at 24 months, we could not evaluate the need for operative treatment at this time. Therefore, restoration survival was set as the primary outcome, as we can determine the restoration failure by the assessment date.
Measured: 24 months
Secondary outcomes (5)
Operative treatment needs of the evaluated restorations (success of restoration)
The necessity to repair the evaluated restorations during the follow-up examinations will be assessed by the Roeleveld et al. (1996) criteria (scores 11, 12, 13 and 30) or Frencken et al. (1996) criteria (scores 2 and 3). The criteria are described below:
Roeleveld et al. (1996): Score 11 - Restoration present, defect at the margin and/or wear of the surface; > 0.5 mm in depth, repair needed; Score 12 - Restoration present; underfilled > 0.5 mm, no gap, repair needed; Score 13 - Restoration overfilled > 0.5 mm, repair needed; Score 30 - Restoration not present, bulk fracture, loose, (partly) lost; repair needed (if still possible without exposing the pulp).
Frencken et al. (2006): Score 2 - Restoration present, marginal defect between 0.5mm and 1.0 mm, repair needed. Score 3 - Restoration present, marginal defect between > 1.0 mm, repair needed.
Measured: 24 months.
Necessity to repair the restoration
The necessity to repair the evaluated restorations during the follow-up examinations will be assessed by the Roeleveld et al. (1996) criteria (scores 11, 12, 13 and 30) or Frencken et al. (1996) criteria (scores 2 and 3). The criteria of the respective scores are described below:
Roeleveld et al. (1996) Score 11 - Restoration present, defect at the margin and/or wear of the surface; > 0.5 mm in depth, repair needed. Score 12 - Restoration present; underfilled > 0.5 mm, no gap, repair needed. Score 13 - Restoration overfilled > 0.5 mm, repair needed. Score 30 - Restoration not present, bulk fracture, loose, (partly) lost; repair needed (if still possible without exposing the pulp). Frencken et al. (2006) Score 2 - Restoration present, marginal defect between 0.5mm and 1.0 mm, repair needed. Score 3 - Restoration present, marginal defect between > 1.0 mm, repair needed.
Measured: 24 months.
Restoration replacement
Necessity of restoration replacement due to restoration loss (total or partial), with no signs of pulp involvement. For restorations involving occlusal surfaces, score 4 of Frencken et al. criteria (1996) will be considered. For restorations involving other surfaces, the scores 21, and 30.
Measured: 24 months.
Presence of secondary caries lesion with dentin exposure
Caries lesion with dentin exposure around evaluated restorations detected in the follow-up examinations will be assessed by the Roeleveld et al. criteria (scores 20 and 21). The criteria of the respective scores are described below:
Score 20 - Secondary caries, discoloration in depth, surface hard and intact, caries within dentin; repair needed. Score 21 - Secondary caries. Surface defect, caries within dentin; repair needed. Frencken criteria system does not deal with this aspect. Therefore, we considered the same parameters described above
Measured: 24 months.
Restored teeth that presents symptoms of pulp inflammation or episode of pain
The restored teeth that presents symptoms of pulp inflammation or episode of pain during the follow-up examinations and need to be extracted will be assessed by the Roeleveld et al. criteria (score 40) for all types of restorations. The criteria of the respective score is described below:
Score 40 - Inflammation of the pulp (restoration still in situ, not categorized in the former categories); fistula or severe pain complaints; extraction needed.
Measured: 24 months.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
There is still great divergence in the aspects related to caries lesions around restorations. The methods and the systems used for the detection of secondary caries lesions have presented low validity. Also, the consequent treatment decisions of this kind of lesions have presented a lot of variation. However, the correct diagnosis of secondary caries may guarantee greater longevity to the restorative treatment, as well as oral health to the patients, reducing the cost and clinical time of the dentists. Therefore, the investigators aimed to perform this study to evaluate and compare two visual criteria for the evaluation of restorations in primary teeth in medium and long term outcomes for the patients, through a randomized clinical study.
