Periodontal Probe Williams Handle Number 30 Qulix - Hu-Friedy - Delynov

What is the Hu-Friedy Williams periodontal probe handle #30 Qulix?

The Williams periodontal probe designed by Hu-Friedy is a manual diagnostic instrument used in periodontology and oral surgery. This specific model is distinguished by its handle #30 and its Qulix marking system. Williams graduations follow a precise sequence of 1-2-3-5-7-8-9-10 mm, intentionally omitting the 4 mm and 6 mm marks to facilitate visual reading during clinical examination. Manufactured by Hu-Friedy Mfg. Co., LLC, this probe is a Class I medical device intended for evaluating the state of the tooth's supporting tissues. Its structure is optimized to offer fine tactile feedback when exploring the gingival sulcus.

What are the clinical indications for this instrument?

The use of this williams periodontal probe is indicated for the millimeter measurement of the depth of the sulcus or periodontal pockets. In clinical practice, it allows dental surgeons to quantify attachment loss, monitor gingival recession, and evaluate furcation involvement. It is also used to check the stability of peri-implant tissues during follow-up visits. This instrument is essential for establishing an accurate periodontal diagnosis, planning scaling and root planing interventions, or delimiting areas requiring debridement surgery or tissue regeneration.

What are the technical characteristics of the Williams Qulix probe?

The Hu-Friedy Williams probe presents rigorous technical characteristics. It features Qulix marking, a black band marking process that ensures optimal visibility even in the presence of oral fluids. Graduations are positioned at intervals of 1mm, 2mm, 3mm, 5mm, 7mm, 8mm, 9mm, and 10mm. The absence of marks 4 and 6 is a historical specificity of the Williams probe aimed at reducing parallax errors and facilitating rapid reading. The handle #30 is a reference specific to the Hu-Friedy catalog, offering a diameter and weight designed for practitioner comfort during repeated probing across the entire dental arch.

What are the contraindications for the use of this device?

In accordance with information from the manufacturer Hu-Friedy Mfg. Co., LLC, the use of this instrument is reserved exclusively for qualified healthcare professionals. Although the regulatory text does not list specific medical contraindications related to the patient, the use of the probe must be adapted to the inflammatory state of the tissues. Excessive pressure during probing should be avoided to prevent damaging the epithelial attachment or causing bleeding that is not representative of the actual periodontal state. It is imperative to read the instructions for use carefully and respect sterilization protocols before any intervention in the mouth.

What are the maintenance precautions for this non-resorbable probe?

As a Class I reusable metallic instrument, the Hu-Friedy Williams probe requires a strict decontamination and sterilization protocol after each use. Although the term resorption does not apply to manual instrumentation, the durability of the Qulix markings depends on compliance with the cleaning agents recommended by the manufacturer. Corrosive solutions that could alter the readability of the millimeter graduations should be avoided. Regular visual inspection of the probe tip is recommended to ensure the absence of bending or dulling, thus guaranteeing the accuracy of clinical measurements essential for patient follow-up.
