In vitro osteogenic/dentinogenic potential of an experimental calcium aluminosilicate cement

ABSTRACT
INTRODUCTION:

Calcium aluminosilicate cements are fast-setting, acid-resistant, bioactive cements that may be used as root-repair materials. This study examined the osteogenic/dentinogenic potential of an experimental calcium aluminosilicate cement (Quick-Set) by using a murine odontoblast-like cell model.

METHODS:

Quick-Set and white ProRoot MTA (WMTA) were mixed with the proprietary gel or deionized water, allowed to set completely in 100% relative humidity, and aged in complete growth medium for 2 weeks until rendered non-cytotoxic. Similarly aged Teflon disks were used as negative control. The MDPC-23 cell line was used for evaluating changes in mRNA expressions of genes associated with osteogenic/dentinogenic differentiation and mineralization (quantitative reverse transcription polymerase chain reaction), alkaline phosphatase enzyme production, and extracellular matrix mineralization (alizarin red S staining).

RESULTS:

After MDPC-23 cells were incubated with the materials in osteogenic differentiation medium for 1 week, both cements showed up-regulation in ALP and DSPP expression. Fold increases in these 2 genes were not significantly different between Quick-Set and WMTA. Both cements showed no statistically significant up-regulation/down-regulation in RUNX2, OCN, BSP, and DMP1 gene expression compared with Teflon. Alkaline phosphatase activity of cells cultured on Quick-Set and WMTA were not significantly different at 1 week or 2 weeks but were significantly higher (P < .05) than Teflon in both weeks. Both cements showed significantly higher calcium deposition compared with Teflon after 3 weeks of incubation in mineralizing medium (P < .001). Differences between Quick-Set and WMTA were not statistically significant.

CONCLUSION:

The experimental calcium aluminosilicate cement exhibits similar osteogenic/dentinogenic properties to WMTA and may be a potential substitute for commercially available tricalcium silicate cements.

NeoMTA Plus is a stainproof, tricalcium silicate-based bioactive cement that can be used universally for vital pulp and other endodontic indications in primary and permanent teeth. NeoMTA Plus is a bioceramic cement that triggers the healing process. With NeoMTA Plus, general dentists, pediatric dentists, and endodontists now have a superior and reasonably priced bioceramic. Dentists praise the multi-use NeoMTA Plus because it mixes more smoothly, is easier to dispense and the unique gel enables more stable placement, washout resistance and faster clinical setting.

New, stain-free light color:

Ideal for pediatric dentistry—won’t discolor teeth
Liquids such as sodium hypochlorite won’t cause discoloration

Multiple indications:

Pulp-capping to base/liner
Pulpotomies to apexification
Sealer to perforation repair
Root-end filling to resorption

Non-cytotoxic

Inhibits bacterial growth* *Tested in vitro. Not a disinfectant

Grey MTA Plus is a bioceramic tricalcium silicate-based Dental Cement, which is slightly more radiopaque than (white) MTA. The light silvery color of MTA Plus is visible during placement. Grey MTA Plus is indicated for both Vital Pulp Therapy and Endodontic procedures. General dentists and endodontists praise the multi-use Grey MTA Plus because it mixes more smoothly and is easier to dispense. The unique gel enables more stable placement, washout resistance and faster clinical setting.

Multiple indications:

Pulp-capping to Base/Liner
Pulpotomies to Apexification
Sealer to Perforation Repair
Root-end Filling to Resorption

New, light grey color:

More radiopaque than the leading white MTAs
Visible for precise placement
Inhibits bacterial growth in vitro of Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Pseudomonas aeruginosa.
Non-cytotoxic

Better mixing, handling and placement:

Finer powder mixes more easily and smoothly
Dispense as little as 0.1 gm
