Spreader #40 ISO handle #30 0.40/28mm black

What is the Spreader #40 ISO handle #30 0,40/28mm black?

The Spreader #40 ISO marketed under the brand Hu-Friedy is a specific manual endodontic instrument. This manual spreader features a tip diameter of 0,40mm, corresponding to ISO standards, and a working length of 28mm. It is equipped with a size #30 handle in black for quick visual identification during clinical procedures. This instrument is designed to assist the practitioner in the critical stages of canal obturation, offering a structure adapted to the precise manipulation of gutta-percha within the endodontium.

What are the clinical indications for this instrument?

This device from the brand Hu-Friedy is indicated for canal obturation procedures in endodontics. More specifically, it is used as a lateral gutta plugger during the cold lateral condensation technique. Its clinical role is to compress the gutta-percha against the dentinal walls of the previously prepared root canal. By creating lateral space, it allows for the successive insertion of accessory gutta-percha cones to achieve a hermetic and three-dimensional seal of the canal system, thereby preventing post-treatment bacterial reinfections.

What are the technical characteristics of the Spreader #40 ISO?

The Spreader #40 ISO from the brand Hu-Friedy is characterized by a tapered tip of 0,40mm in diameter, respecting ISO codification standards. The working part measures 28mm, providing sufficient reach for the majority of root anatomies encountered in daily practice. The ergonomic size #30 handle is associated with the black color code. As a manual spreader, it provides tactile feedback essential to the dental surgeon for evaluating resistance and insertion depth during the condensation of gutta-percha in the canal.

What are the contraindications for the use of this device?

According to information provided by the manufacturer Hu-friedy, the use of this device is strictly reserved for qualified healthcare professionals. Contraindications include the use of the instrument by untrained personnel or in non-sterile conditions. Although the source text does not list specific pathologies, use should be avoided if the canal anatomy presents extreme curvatures that risk compromising the integrity of the instrument or if the clinical diagnosis contraindicates tooth preservation by endodontic treatment.

What are the precautions for use and maintenance?

The Spreader #40 ISO is a non-resorbable instrument that requires rigorous handling. Before any use, it is imperative to carefully read the instructions provided by the manufacturer Hu-friedy. The practitioner must ensure the appropriate decontamination and sterilization of the device before each intervention. During lateral condensation, excessive pressure must be avoided to prevent any risk of root fracture or deformation of the instrument tip. Visual verification of the shaft's condition before insertion is recommended.

Who is the manufacturer and what standards are respected?

The official manufacturer of this spreader is Hu-friedy, located at 3232 N. Rockwell St. Chicago, Il 60618 USA. This medical device belongs to Class I according to current regulations. Compliance with manufacturing standards guarantees the conformity of the instrument for professional use in dental surgery. The CE marking is not specified in the current technical data, but the product follows strict directives relating to Class I medical devices, thus ensuring the traceability and safety necessary for endodontic procedures performed in the clinic.
