Assessment of the Depth of Clinically Detected Approximal Caries Lesions Using Digital Imaging Fiber-Optic Transillumination in Comparison to Periapical Radiographs.

ABSTRACT: Objectives:The aim of present prospective clinical trial was to assess the depth of clinically detected approximal caries lesions using digital imaging fiber-optic transillumination in comparison to periapical radiographs. Material and Methods:One calibrated examiner diagnosed 31 approximal carious lesions in 10 patients with a mean age of 21.8 (SD 1.1) years. The lesions were assessed using digital imaging fiber-optic transillumination (DIFOTI) and digital periapical radiographs (PA). Depending on the depth of the lesions, scores for demineralisation in PA (R) and DIFOTI (F) images were given by two examiners: R0/F0 - no demineralisation, R1/F1 - demineralisation confined to the outer half of the enamel, R2/F2 - into the inner half of the enamel, 3/3 - along the amelodentinal junction, R3/F3 - into the outer half of dentine, R4/F4 - into the inner part of the dentine. Spearman's rank correlation coefficient and kappa were calculated. Results:Spearman's rank correlation coefficient between DIFOTI and PA was 0.031 (P > 0.05), kappa was 0.077. In 26% of the cases, DIFOTI showed higher scores of demineralisation, relative to PA. In 36% of the cases, PA showed higher scores of demineralisation than DIFOTI. PA showed demineralisation into the outer and inner half of the dentine in 89% of the cases with underlying shadow and in 70% of the cases with opacities. Conclusions:Digital imaging fibre optic transillumination and periapical radiographs produce evaluations of the depth of approximal caries lesions that do not match.

Project description:BackgroundApproximal surfaces are a challenge to caries lesions control. Silver diamine fluoride (SDF) is a simple,low-cost and promisor intervention for arresting caries lesions, but it has never been tested on approximal surfaces. Our aim is to evaluate the efficacy and cost-efficacy of SDF in arresting initial lesions compared to resin infiltration and exclusively flossing (control group). Our second aim is to assess discomfort and satisfaction regarding interventions.Methods/designThis is a randomized clinical trial, double-blinded, placebo-controlled study. Children/adolescents presenting at least one approximal initial caries lesion in primary molars/permanent premolars and molars will be included. Surfaces with advanced dentine lesions identified by radiography and participants who refuse to participate or present negative behaviors will be excluded. A minimum sample size of 504 surfaces will be required for each subgroup. Individuals will be randomly allocated in three groups of interventions: SDF, resin infiltration, and control group. Depending on the allocation, the patients will receive the active treatment and respective placebo therapies. All patients will be oriented to daily flossing the included surfaces. Our primary outcome will be caries progression by clinical and radiographic examinations. Appointments will be timed and costs of materials will be considered to calculate cost-efficacy. Patient discomfort will be assessed after interventions. Parent and patient satisfaction with the treatment will be collected after treatment and in the last follow-up visit. Individuals will be assessed at 1 and 3 months after treatment to evaluate dental biofilm and at 6, 12, and 24 months to assess caries progression by visual examination and/or radiography. Multilevel analyses will be used to verify if the type of treatment influenced on the tested outcomes. Costs will be compared and analyses of cost-efficacy will be performed. Poisson analysis will test the association between intervention and reported discomfort and satisfaction.DiscussionOur hypothesis is that SDF is the most cost-efficacious option from all tested interventions. If our hypothesis is confirmed, the use of SDF in private and public contexts could represent an easier and effective option in the treatment of enamel approximal caries in children/adolescents.Trial registrationClinicalTrials.gov (NCT01477385), Initial release: 11/16/2011: last update: 06/02/2014.
