Treatment of Proximal Superficial Caries Lesions on Primary Molar Teeth with Resin Infiltration and Fluoride Varnish versus Fluoride Varnish Only: Efficacy after 1 Year

Abstract

This split-mouth study aimed to assess the efficacy of resin-infiltrated lesions covered by fluoride varnish (FV) versus FV treatment only of proximal lesions on deciduous molar teeth. The study lasted for 1 year. Children with 2 or more superficial proximal lesions on deciduous molar teeth detected on bitewing radiographs were included. After written parental consent, two lesions in each of 50 children were randomly allocated to one of two treatments: resin infiltration followed by FV (2.26% F) application (test lesion) versus only FV (control lesion). The ICDAS scores of the selected lesions were recorded by 2 clinicians before the treatments (weighted kappa for inter- and intra-examiner agreement >0.79). FV was applied to both test and control lesions 6 and 12 months after the first treatment. After 1 year ICDAS scores were obtained for 42 children and radiographs for 39. One external examiner not familiar with the study scored the radiographs twice (weighted kappa 0.88). Baseline mean age of the children was 7.17 ± (SD) 0.68 and mean def-s was 8.1 ± (SD) 6.9. After 1 year the ICDAS scores of 31% of the test lesions and 67% of the control lesions had progressed (p < 0.01). Radiographically, 23% of the test lesions and 62% of the control lesions had progressed (p < 0.01). Thus, the clinical and radiographic therapeutic effect of both resin infiltration/FV over FV alone was >35% and significant. To conclude, resin infiltration in conjunction with fluoride varnish seems promising for controlling proximal lesion progression on deciduous molar teeth.

Therapeutic potential of Brazilian fluoride varnishes: an in vivo study

“…This finding corroborates those of previous studies (6,10,12,16,18,19). There was a 45.7% reduction in WSL size, which is in agreement with previous studies (9,10,12,16).…”

The influence of interdental spacing on the detection of proximal caries lesions in primary teeth

“…Certain discrepancies could be attributed to different samples or different methodologies. 14,20 Our results, however, demonstrated that the presence of proximal spacing did not influence the performance of proximal caries detection methods. Most likely, this finding reflects the fact that most of the proximal sites included in our study did not present wide biological spacing.…”

Efficacy of fluoride varnish for prevention of white spot lesions during orthodontic treatment with fixed appliances: A systematic review study

“…The studies (Hammad et al, 2012;Mueller et al, 2006;Paris and Meyer-Lueckel, 2010) showed a good effect of resin infiltration on WSLs after debonding orthodontic brackets. The studies concluded that treatment with resin infiltration in conjunction with fluoride varnish is promising for controlling proximal lesions (Ekstrand et al, 2010) and in fact, teeth treated with resin infiltration showed higher Vickers hardness values than untreated teeth (Palamara, 2010). Based on our knowledge, there were no study on the efficacy of resin infiltration versus fluoride varnish+ CHX for WSL treatment; therefore, more studies in the future are necessary to follow up on this comparison.…”
