Devilat Devitalizing Paste (3 g syringe) – Effective and Comfortable Anesthesia for Endodontics (Latus)

Purpose and General Description

Devilat (Latus) is a high-quality devitalizing paste in a convenient 3 g syringe, designed for the irreversible devitalization (killing) of the dental pulp in the treatment of pulpitis. It is an indispensable tool in cases where the use of anesthesia is difficult or contraindicated, as well as for patients who have a heightened fear of injections.

Devilat paste ensures rapid and reliable pulp necrosis and guarantees a convenient and controlled process for the clinician. It is an excellent alternative to arsenic preparations as it contains less toxic active components.

Key Composition and Mechanism of Action

The formula of Devilat paste is carefully balanced for maximum effectiveness and minimization of pain:

• Paraformaldehyde ($30\%$): This is the main devitalizing component. It causes chemical necrosis (destruction) of the pulpal tissue. Its action is milder and more controlled compared to arsenic, reducing the risk of periodontal damage.

• Lidocaine Hydrochloride: This is a powerful local anesthetic. Its inclusion in the paste provides rapid and deep pain relief immediately after application, which significantly reduces or completely eliminates the pain that can arise during the action of paraformaldehyde. This makes the devitalization process comfortable for the patient.

• Fibrous Filler and Excipient: Serve to form the paste, ensure its plasticity, facilitate placement into the cavity, and provide adhesion to the dentin.

Advantages and Unique Characteristics

• Safe Alternative to Arsenic: Contains paraformaldehyde, which is considered less toxic to periapical tissues than arsenic, while still providing high devitalizing ability.

• Immediate Pain Relief: Thanks to the presence of lidocaine, Devilat paste almost immediately eliminates pulpal pain that often occurs upon contact of paraformaldehyde with vital pulp.

• Convenient Packaging ($3 \text{ g}$ syringe): Ensures accurate, hygienic, and economical dosing of the material. The syringe allows the necessary amount of paste to be easily placed directly into the carious cavity or onto the exposed pulp.

• Rapid Effect: Devitalization usually occurs within $24-72$ hours (depending on the condition of the pulp and individual characteristics).

• Easy Removal: The paste has a noticeable color, simplifying its visualization and complete removal during the subsequent visit.

• Minimal Risk of Complications: When following the instructions, the risk of toxic effects on the periodontium is minimized.

Indications for Use

• Pulpitis: Used for irreversible devitalization of the pulp before its extirpation (removal).

• Treatment of Children and Adolescents: Particularly useful in cases where the child cannot tolerate injection anesthesia.

• Contraindications to Local Anesthesia: Used when the patient is contraindicated against the administration of anesthetics (e.g., allergic reactions).

• Incomplete Anesthesia: As an additional agent if local anesthesia has not provided a complete analgesic effect.

Instructions for Use (Scheme)

1. Isolation and Preparation: The tooth is isolated. The carious cavity is opened.

2. Pulp Exposure: Direct access to the pulpal chamber (or pulp horn) is secured.

3. Paste Placement: A small ball of Devilat paste (the size of a pinhead) is placed onto the exposed pulp area.

4. Isolation and Sealing: The tooth cavity is hermetically sealed with a temporary filling.

5. Exposure Time: The paste remains in the cavity for 1-3 days.

6. Second Visit: During the subsequent visit, the pulp is removed painlessly (as it is already devitalized), and standard endodontic preparation of the root canals is performed.

Devilat is the choice of professionals who value reliability, speed of action, and patient comfort during pulp devitalization.
