Comparative evaluation of push-out bond strength of NeoMTA Plus with Biodentine and white ProRoot MTA.

ABSTRACT
OBJECTIVE:
The aim of this in vitro study was to evaluate the bond strength of a new calcium silicate cement, Neo MTA Plus (Avalon Biomed Inc. Bradenton, FL, U.S.A) by comparing ProRoot MTA and Biodentine.
MATERIAL AND METHODS:
Sixty dentin slices were instrumented to achieve a diameter of 1.3 mm. Group 1: white ProRoot MTA, group 2: Biodentine, group 3: Neo MTA Plus – G (powder mixed with gel), group 4: Neo MTA Plus – W (powder mixed with distilled water) were loaded into cavities. The push-out bond strength values were measured. Data were analyzed using Welch ANOVA with Bonferroni correction p = 0.05. Failure modes (adhesive, cohesive, and mixture) were analyzed.
RESULTS:
The highest bond strength value was recorded in Neo MTA Plus mixed with gel (5.23 ± 1.78 MPa), whereas white ProRoot MTA (2.57 ± 0.66 MPa) had the lowest. Bond strength values of Neo MTA Plus
mixed either with gel or with distilled water were statistically different from both white ProRoot MTA and Biodentine (2.61 ± 0.70 MPa) (p < 0.05). Adhesive failure was predominantly observed in all groups.
CONCLUSION:
Neo MTA Plus could be considered as alternatives to the ProRoot MTA and Biodentine due to its better performance in bonding to root dentin.

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
