Histology of NeoMTA Plus and Quick-Set2 in Contact with Pulp and Periradicular Tissues in a Canine Model.

ABSTRACT:
The purpose of this study was to compare the healing of pupal and periapical tissues in dogs after exposure to NeoMTA Plus and Quick-Set2 after pulpotomy and root-end surgery procedures.

METHODOLOGY:
Seventy-two teeth (36 for each procedure) in 6 beagle dogs received pulpotomy or root-end surgery using either NeoMTA Plus or Quick-Set2. The dogs were sacrificed at 90 days, and the teeth and surrounding tissues were prepared for histologic evaluation. Sixty teeth were evaluated and scored histologically (29 with pulpotomies and 31 with root-end resections). Specimens were scored for inflammation, quality and thickness of dentin bridging, pulp tissue response, cementum and periodontal ligament formation, and apical bone healing.

RESULTS:
Both materials displayed favorable healing at 90 days. The only significant difference was the quality of dentin bridge formation in pulpotomies using NeoMTA Plus compared with Quick-Set2.

CONCLUSIONS:
Quick-Set2 and NeoMTA Plus had similar effects on inflammation, pulp response, periodontal ligament and cementum formation, and apical tissue healing in dogs. NeoMTA Plus had superior dentin bridge quality compared with Quick-Set2.

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
