Correlation between Microleakage and Absolute Marginal Discrepancy in Zirconia Crowns Cemented with Four Resin Luting Cements: An In Vitro Study
Objectives. To evaluate microleakage and absolute marginal discrepancy (AMD) and to assess correlation between AMD and microleakage with four resin luting cements. Material and Methods. 20 extracted human third molars were prepared for full-coverage crowns. 20 zirconia copings were made (LAVA, 3M ESPE) and cemented. Specimens were randomly allocated for each used type of cement into 4 groups, R...
متن کاملMicroleakage of cements for stainless steel crowns.
Microleakage is related to recurrent decay, inflammation of vital pulps, and reinfection of previously treated root canals. The purpose of this investigation was to compare the abilities of new adhesive cements and conventional nonadhesive controls to prevent microleakage under stainless steel crowns on primary anterior teeth. Standardized preparations were made, and stainless steel crowns were...
متن کاملMicroleakage of three luting agents used with stainless steel crowns.
The microleakage through margins of stainless steel crowns cemented with polycarboxylate, zinc phosphate, or glass ionomer cement was evaluated by measuring the amount of 4SCa leakage through the crown margins through 56 days after cementation in an in vitro environment. There was no cement-specific difference in marginal leakage as measured by this technique. The amount of leakage for each cem...

متن کاملMicroleakage of Four Dental Cements in Metal Ceramic Restorations With Open Margins.
BACKGROUND Fixed prosthodontics is a routine dental treatment and microleakage is a major cause of its failure. OBJECTIVES The aim of this study was to assess the marginal microleakage of four cements in metal ceramic restorations with adapted and open margins. MATERIALS AND METHODS Sixty sound human premolars were selected for this experimental study performed in Tehran, Iran and prepared ...
متن کاملMicroleakage of various cementing agents for full cast crowns.
OBJECTIVES To evaluate microleakage and marginal gaps in full cast crown restorations bonded with six different types of cementing agents. METHODS Sixty non-carious human premolars and molars were prepared in a standardized manner for full cast crown restorations. The mesial and distal margins were located in dentin, while the vestibular and palatal/lingual margins were located in enamel. Cro...
