Properties of NeoMTA Plus and MTA Plus cements for endodontics

Abstract:

To test a novel calcium silicate cement mixed with a water-based gel (NeoMTA Plus) with regard to chemical-physical properties and apatite-forming ability.

METHODOLOGY:
NeoMTA Plus (Avalon Biomed Inc. Bradenton, FL, USA; lot. 2014090301) and a commercial MTA-based material with similar properties (MTA Plus, Prevest Denpro Limited, Jammu, India; lot. 41001) were tested for ion-releasing ability, initial and final setting times, radiopacity, open and impervious porosity and apparent porosity, water sorption, weight loss, solubility, ability to nucleate calcium phosphates (CaP) after immersion in HBSS (Hank’s Balanced Salt Solution) by ESEM-EDX and micro-Raman spectroscopy. The results were analysed statistically with the anova test (P < 0.05).

RESULTS:
NeoMTA Plus had a prolonged setting time (315 min) and a satisfactory radiopacity (3.76 mm Al). Calcium and hydroxyl ion release was significantly greater and more prolonged in comparison with MTA Plus (P < 0.05). Both NeoMTA Plus and MTA Plus had high values of open porosity and solubility. ESEM-EDX and micro-Raman confirmed the ability to nucleate calcium phosphates on their surface after immersion in HBSS.

CONCLUSIONS:
NeoMTA Plus is a new calcium silicate-based cement for root filling with an adequate radiopacity and prolonged setting time. The ion release and CaP-forming ability could increase stability of the root filling and promote endodontic and periodontal tissue regeneration, enhancing the bioactivity and biocompatibility of the material.

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
Unique gel for stable placement
Washout resistant
No special equipment required

Smart, convenient packaging:

Protects fine powder in desiccant-lined bottle
Easy to dispense powder as needed
Dropper-tip gel bottle minimizes waste
