Description

Preva Calci Paste – Non Hardening Calcium Hydroxide

Preva Calci Paste is a ready-to-use, radiopaque, non-hardening calcium hydroxide paste designed for temporary intracanal medication during endodontic treatment. Because it delivers a high alkaline pH of approximately 12.8, it creates a strong antibacterial environment inside the root canal. As a result, it supports healing and stimulates hard tissue formation.

In addition, the hydrophilic formulation allows the material to adapt effectively within the moist canal environment. Therefore, clinicians can achieve consistent placement and predictable therapeutic outcomes.

Moreover, the radiopaque composition enables clear visualization under radiographic examination. Consequently, dentists can monitor placement and evaluate treatment progress with confidence.

Clinical Indications

• Apexogenesis in permanent and primary teeth with incomplete root development
• Apexification procedures in teeth with open apices
• Formation of an osteoid or cemental barrier
• Conservative management of chronic apical periodontitis
• Temporary intracanal medication during root canal treatment
• Management of incompletely formed apices in primary teeth associated with periodontitis

How Preva Calci Paste Supports Endodontic Success

Preva Calci Paste actively promotes biological repair. Specifically, it:

• Encourages dentinal and cemental barrier formation
• Supports continued root growth in immature teeth
• Promotes regeneration of periapical tissues
• Stimulates secondary dentine formation
• Reduces periapical changes during intracanal medication

Because the material remains non-hardening, clinicians can remove and replace it easily whenever required. Thus, it fits well into multi-visit endodontic protocols.

Why Choose Preva Calci Paste?

• Delivers strong antimicrobial action due to high pH
• Promotes hard tissue formation and biological repair
• Radiopaque for accurate radiographic monitoring
• Hydrophilic formulation adapts to moist canals
• Non-hardening consistency allows easy removal
• Supplied in a convenient ready-to-use syringe

Overall, Preva Calci Paste gives clinicians a dependable and biologically supportive intracanal medicament for predictable endodontic care.

Frequently Asked Questions

What is Preva Calci Paste used for?

Preva Calci Paste is used as a temporary intracanal medicament during endodontic treatment. It is commonly indicated for apexogenesis, apexification, management of chronic apical periodontitis, and stimulation of hard tissue formation.

Is Preva Calci Paste a permanent root canal filling material?

No. Preva Calci Paste is a non-hardening calcium hydroxide paste intended for temporary intracanal use. It must be replaced periodically and followed by permanent root canal obturation once treatment objectives are achieved.

How does Preva Calci Paste work?

Preva Calci Paste has a high alkaline pH of approximately 12.8. This creates an antimicrobial environment inside the root canal and promotes the formation of dentinal or cemental barriers, encouraging healing of periapical tissues.

How long can Preva Calci Paste remain inside the canal?

Depending on the treatment protocol:

• For apexification and apexogenesis: typically replaced after 3–4 weeks initially, then reassessed every 2–3 months.
• For chronic apical periodontitis: usually left for 7–10 days before reassessment.
• Clinical and radiographic evaluation determines replacement timing.

How do you remove Preva Calci Paste from the root canal?

Preva Calci Paste can be removed using standard endodontic irrigation and instrumentation techniques:

• Irrigation with sodium hypochlorite (NaOCl)
• Use of EDTA solution to assist in cleaning
• Mechanical agitation with files
• Ultrasonic activation (if required)
  Because it is non-hardening, it can be removed relatively easily compared to set materials.

Is Preva Calci Paste radiopaque?

Yes. It contains zirconium oxide, which makes the material radiopaque. This allows clinicians to verify placement and monitor treatment progress through radiographs.

Can Preva Calci Paste be used in primary teeth?

Yes. It may be used in temporary (primary) teeth, especially in cases involving incompletely formed apices associated with periodontitis, as per clinical judgment.

What precautions should be taken during use?

• Use rubber dam isolation whenever possible.
• Avoid excessive extrusion beyond the apex.
• Avoid contact with eyes and soft tissues.
• Do not use in patients with known hypersensitivity to any component.
• For professional dental use only.

Why is it important to tighten the cap immediately after use?

Preva Calci Paste contains hydrophilic components. Leaving the syringe uncapped may:

• Cause drying of material at the dispensing tip
• Alter consistency
• Affect working characteristics
• Reduce shelf life
• Always wipe the syringe tip clean and tighten the cap immediately after use to maintain product integrity.

Does Preva Calci Paste promote root development?

Yes. In apexogenesis procedures, it may assist in continued root growth and development by creating favorable biological conditions for hard tissue formation.

Can it help in periapical healing?

Yes. The alkaline environment supports antimicrobial action and may reduce periapical changes, promoting regeneration of bone and surrounding tissues.

What happens if the material is extruded beyond the apex?

Excessive extrusion should be avoided. While calcium hydroxide is biologically compatible, overextension may cause irritation. Careful placement and radiographic verification are recommended.

Is Preva Calci Paste easy to dispense?

Yes. It is supplied in a ready-to-use syringe along with intracanal tips , allowing controlled placement into the root canal with minimal waste.

Can it be used in regenerative endodontic procedures?

Preva Calci Paste may support pulp regenerative capacity and hard tissue stimulation when used according to accepted clinical protocols.
