This study aimed to explore the interactions between adhesive resins/liners and impression materials when using immediate dentin sealing (IDS). Inlay preparations were performed on extracted molars. Impressions of the specimens were made with (test) or without (control) IDS. Four different adhesive systems were used: Optibond FL, Scotchbond Universal, Optibond XTR, and Filtek LS. Two impression materials were used: Express STD or Impregum F. For each adhesive and impression material, six surface treatments were evaluated. Additional groups were tested by adding a liner on top of the IDS layer. The surfaces were scored in terms of adhered or unpolymerized impression material. No interactions were observed in control groups. The combination of vinyl polysiloxane (VPS) and simplified adhesives showed 100% unpolymerized impression material. Optibond FL demonstrated VPS inhibition (66.6%) only when untreated. The combination of polyether and IDS showed unpredictable results with varying amounts of negative interactions (0% to 100%). No interactions were observed when a liner was applied. Only the combination of VPS and Optibond FL yielded 100% perfect impressions when used in conjunction with any of the surface treatments. All other adhesives resulted in significant unpolymerized VPS even after surface treatment. Am J Esthet Dent 2013;3:200208. doi: 10.11607/ajed.0073
