Travex 37 (Travex)

Travex-37 (Travex) - phosphoric acid, known as a material for total etching (use of acid to improve adhesion when working with mixed filling materials) enamel and dentin, used in dentistry before the restoration of carious surfaces tooth.

The technique of the process of such etching involves the simultaneous treatment of the enamel and dentin surfaces with an acidic agent.

The etching material contains 37% of the highest grade phosphoric acid, aerosil, polymer, distilled water and methylene blue. Due to the strong viscosity of Travex-37, maximum working characteristics are guaranteed, which allow to further increase the adhesion strength of hard dental tissues with filling material.

The gel is characterized by increased ticstoriness, therefore, after being applied to the enamel surface, it does not dry out, does not drip onto the gums, it is securely fixed in the area of ​​use and is very easily washed off. In order to increase the effectiveness of antiseptic indicators, an antibacterial component, cetylpyridine chloride, is used in the production process of the etchant.

Release form: economical packaging; packaged in 3 syringes of 3.5 ml. Includes 20 interchangeable application tips for precise, easy application and control.

Method of administration and dosage

According to the instructions for use of Travex-37, you need to separate the protective cap from the syringe and insert a cannula for application instead. Squeeze the required amount of acid onto the selected area of ​​the tooth and wait 20-25 seconds. Then the agent should be removed from the treated area by abundant irrigation with water, using a saliva ejector, a special vacuum cleaner and cotton swabs.

The duration of the removal of the etchant with running water must necessarily correspond to the duration of the action of the acid, i.e. 25 seconds. Dry to a semi-dry state. As a result, the treated surface is prepared for subsequent actions.

There are several factors that influence the effect of acid etching of enamel:

• the time of exposure of the gel to the enamel;
• rinsing time with water;
• the degree of treatment of the enamel surface before the etching process itself;
• the state of the enamel and the degree of its mineralization.

The quality of the dental tissue etching process is assessed due to the following indicators:

• the remains of the gel are completely washed off with water;
• the enamel surface is dry and chalky;
• slightly shiny, but not overdried dentin.

The likelihood of getting the product on the mucous membranes should be excluded, since Travex contains phosphoric acid. Otherwise, the mucous membrane must be thoroughly and repeatedly rinsed with water.

Provided for professional use in healthcare facilities only. Do not use at home or for other purposes.

Indications and contraindications

Gel Travex is recommended for total etching of enamel or dentin for direct and indirect restorations. It also applies to processing fissure (natural depressions, irregularities and cracks on the chewing surfaces of the teeth) in front of them sealing. Improves the fixation of the filling material not only with the enamel surface, but also with dentin.

Contraindication to use is hypersensitivity to one of the components of the material. Use only for the intended purpose.

Precautions and storage conditions

The phosphoric acid in the gel can cause burns. Do not allow contact with the oral mucosa or skin. Otherwise, it is immediately required to remove the material with hydrophilic cotton wool moistened with water, and then rinse off the residues with water. Also, if the product accidentally gets into the eyes, be sure to rinse them with water and promptly seek help from specialists.
