Study summary
P - Population/Patient Problem Adult patients requiring full coverage porcelain-fused-to-metal (PFM) crown restorations I - Intervention PFM crowns veneered with porcelain system cemented using self-adhesive resin cement in DUAL-CURED mode (light-cured for 20 seconds per surface) C - Comparison PFM crowns veneered with porcelain system cemented using self-adhesive resin cement in SELF-CURED mode (no light curing, 5 minutes self-cure) O - Outcome(s)
* Primary: Retention of PFM crowns (Modified USPHS criteria)
* Secondary: Marginal adaptation, recurrent caries, marginal discoloration (Modified USPHS criteria) T - Time 18-month follow-up period with evaluations at baseline, 6, 12, and 18 months
