OT primer plus

OT Primer Plus CS200 takes dentin adhesion to the next level. Combining the proven power of DMSO technology with chlorhexidine and a controlled hemostatic system, this multifunctional pretreatment enhances resin infiltration while delivering potent antibacterial protection and effective bleeding control.

Designed for challenging restorative cases, OT Primer Plus CS200 not only strengthens the hybrid layer and reduces nanoleakage, but also disinfects dentin surfaces and manages bleeding in deep cavity preparations or accidental pulp exposure.

As part of our next-generation adhesive system, OT Primer Plus CS200 provides maximum reliability for both etch-and-rinse and self-etch protocols, with added clinical safety and control.

Enhanced Resin Infiltration

DMSO technology improves monomer penetration into collagen fibrils for deeper, stronger bonding.

Superior Hybrid Layer Stability

Reduces nanoleakage and reinforces long-term bond integrity.

Potent Antibacterial Action

2% chlorhexidine delivers strong bactericidal activity — especially effective against Streptococcus and Lactobacillus species.

MMP & Cathepsin K Inhibition

Helps prevent enzymatic degradation of the hybrid layer.

Integrated Hemostatic Control

Rapid bleeding management in deep cavities and superficial pulp exposure.

Reduced Post-Operative Sensitivity

Improves dentin sealing and limits tubular fluid movement.

Universal Compatibility

Works seamlessly with all major adhesive systems (etch-and-rinse and self-etch).

Clinical Confidence in Complex Cases

Ideal for deep preparations, high caries-risk patients, and situations requiring enhanced disinfection.

Application

• Apply before any dental adhesive
• Application time: 40–60 seconds
• Chemically activated — no light curing required

In etch-and-rinse protocols:
Apply after rinsing the etchant and before adhesive placement.

In self-etch protocols:
Apply to prepared dentin before adhesive.

In accidental pulp exposure:
Apply directly to control bleeding and disinfect prior to pulp protection procedures.
