64th ORCA Congress. July 5-8, 2017, Oslo, Norway: Abstracts

The aim of this in vivo study is to report on the combined use\udof a fluorescence intraoral camera and transparent sealant for the\udclinical monitoring of pits and fissures. 96 permanent molars with\uda ICDAS II code 0, 1, or 2, (in 48 patients aged 12–14) were registered\udat the First Observation Unit (Oral and Maxillofacial Sciences\udDepartment), Sapienza University, Rome. Clinically selected\udteeth were double-checked using a VistaCam iX Proof (Durr Dental\udAG) and sealed with a transparent sealant (ControlSeal, VOCO\udGmbH), following the established indications for use if a pit and\udfissure condition was confirmed within the camera’s internal cutoff\udpoint of 1.5 (“early enamel demineralization”). Clinical followup\udwas performed using VistaCam at 6 and 12 months to assess\udsealant retention and any demineralization trend. At baseline,\ud57.4% of the registered teeth were sound, both visually and when\udusing the fluorescence camera, 42.6% presented an early demineralization\ud(<1.5 with VistaCam and ICDAS II 1- 2). Subsequent\udVistaCam assessment of surfaces underlying the transparent sealant\udtotally confirmed initial evaluations. Complete sealant retention\udrated 95% at 6 months, and 91% at 12 months. No case of\udcomplete detachment was observed. At the 12-month follow-up,\udVistaCam measurements resulted stable in the whole sample, except\udfor one permanent molar, which presented a demineralization\udincrement and partial sealant retention. Visual and fluorescence\udassessments were consistent and feasible. Incomplete sealant\udretention occurred in 5% of cases at 6 months and 9% of cases at\ud12 months and was probably due to procedure imperfections. The\udcombined use of transparent sealant and a fluorescence camera\udshows clinical effectiveness and diagnostic efficacy for occlusal\udsurface monitoring
