简要总结

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.

详细描述

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.

入选标准

  • Children who sought dental treatment in our dental school (School of Dentistry, University of Sao Paulo, Sao Paulo, Brazil)
  • Children aged 3 to 6 years
  • Children with at least one restoration on a primary tooth of any material, on any dental surface and regardless of its condition.

排除标准

  • Children whose parents refuse to participate of the research
  • Children who refuse to participate of the research or exhibited behavioral problems during the initial appointment
  • All child's restorations will be included in the evaluation, except for restorations presenting fistula, abscess, pulp exposure, history of spontaneous dental pain or mobility.

结局指标

主要结局

Restoration survival

时间窗: 24 months

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.

次要结局

  • Restored teeth that presents symptoms of pulp inflammation or episode of pain(24 months.)
  • Presence of secondary caries lesion with dentin exposure(24 months.)
  • Operative treatment needs of the evaluated restorations (success of restoration)(24 months.)
  • Necessity to repair the restoration(24 months.)
  • Restoration replacement(24 months.)
