In Vitro Evaluation of Cell Compatibility of Dental Cements Used with Titanium Implant Components

Abstract

Despite previous studies that showed enhanced cpTi corrosion activity for fluoride-containing compositions (NIB and ZP), there was no significant difference in cytotoxicity between cement alone and cemented-cpTi. In general, the MC3T3-E1 preosteoblast cells were more sensitive than HGF cells to cement composition. Ultimately, cement composition played a significant role in maintaining host cell compatibility. Results of this work help illustrate the impact of different cement formulations on host cell health and emphasize the need for understanding material properties when selecting certain formulations of dental cements, which can ultimately influence the survival of dental implant systems.

Long‐term retention of lithium disilicate crowns with a current bioactive cement

“…The type of cement most preferred for cementation of lithium disilicate crowns is composite resin with adhesive and use of a silanating agent. 1 However, given the attractiveness of a bioactive cement for some practitioners, the simplicity of its use and evidence of biocompatibility, 24,25 for KC was in agreement with results from another study. 7 During testing, a distinctive "pop" was heard with crown removal for all 24 specimens.…”

“…The type of cement most preferred for cementation of lithium disilicate crowns is composite resin with adhesive and use of a silanating agent 1 . However, given the attractiveness of a bioactive cement for some practitioners, the simplicity of its use and evidence of biocompatibility, 24,25 it was important to document the ability of CM in retaining crowns after long‐term storage and cycling. However, both cements tested are in the range of clinical acceptability and if a practitioner wishes to choose a bioactive cement when cementing lithium disilicate crowns, CM appears to be the best choice.…”

Can Dental Cement Composition Affect Dental Implant Success?

“…Overall, soft-tissue forming cells were found to be less sensitive than the other two cell lines, which confirmed the results obtained in a previous study. 12 The lack of sensitivity in the fibroblasts is probably a result of its ability to withstand the constant physiological and chemical changes that take place in the oral environment. On the other hand, dental bone tissue is not usually subjected to the abrasiveness of these conditions, and dental cement was not thought to come into contact with it until recent biopsy studies of cement- retained restorations proved otherwise.…”

Assessment of characteristics and cytotoxic effects of 316L stainless steel coated with a new titanium oxide nano-structure coating method

“…The TiO 2 coating with antibacterial and antiadherent properties and good biocompatibility had been reported in many studies. MC3T3-E1 cells were used for cytotoxicity assessment in the dentistry literature 17,18) . A significant difference in MC3T3-E1 cell morphology was observed in this study.…”

“…For the cytotoxicity study, MC3T3-E1 mouse preosteoblasts cells were used 17,18) . Cells were cultured in alpha-minimum essential medium (α-MEM) with 10% fetal bovine serum and 1% penicillin/streptomycin (PS) under 37ºC, 5% CO 2 environment.…”
