Device Story

Waterlase is an Er,Cr:YSGG laser system for dental hard and soft tissue procedures. It uses laser energy combined with water atomization (hydrokinetic technology) to cut, etch, or ablate tissue. For hard tissue, the water spray assists in tissue removal, cooling, and hydration; for soft tissue, it provides cooling and hydration. A flexible fiberoptic handpiece delivers laser energy, with a visible aiming beam to pinpoint treatment areas. Clinicians (dentists) adjust power output, pulse energy, repetition rate, and air/water flow rates based on the procedure. The device enables precise tissue management, potentially reducing the need for traditional mechanical tools and improving clinical outcomes in periodontal and endodontic applications.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Er,Cr:YSGG laser source; hydrokinetic water atomization system; flexible fiberoptic handpiece; adjustable power, pulse energy, repetition rate, and air/water flow; visible aiming beam.

Indications for Use

Indicated for adult and pediatric patients requiring hard tissue dental procedures (cavity prep, caries removal, endodontics, bone surgery, periodontal procedures) and soft tissue oral procedures (incision, excision, ablation, coagulation, biopsy, frenectomy, gingivectomy, etc.). Contraindicated for patients with specific medical conditions (e.g., anesthesia allergies, heart/lung disease, bleeding disorders, immune deficiency) where clinical judgment deems local procedures inappropriate.

Regulatory Classification

Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.

#### Waterlase®

#### Device Description:

The Waterlase hydrokinetic dental laser system is a diverse device utilized to perform a variety of dental applications. For hard tissue procedures the Waterlase uses the Erbium, Chromium: Yttrium, Scandium, Gallium Gamet (Er,Cr. YSGG) laser in combination with advanced water atomization technology to cut, remove, roughen and etch tissues. Soft tissue procedures are performed using a different mode of operation where direct Er.Cr.YSGG laser energy is applied to incise, excise or ablate these tissues. In soft tissue procedures the water spray is applied for hydration, cooling or to keep tissues clean. For hard tissue applications the spray is part of the tissue removing process as well as hydration, cooling and keeping the tissues clean.

A flexible fiberoptic handpiece delivers the Waterlase laser energy. A visible light emitted from the handpiece distal end pinpoints the area of treatment. In both hard and soft tissue applications the power output, pulse energy, repetition rate and air and water flow rates are adjustable to specific user requirements.

Patient risk must always be considered and fully understood before clinical treatment. The clinician must completely understand the patient's medical history prior to treatment. Exercise caution for general medical conditions that might contraindicate a local procedure. Such conditions may include allergy to local or topical anesthetics, heart disease, lung disease, bleeding disorders, sleep apnea or an immune system deficiency. Medical clearance from patient's physician is advisable when doubt exists regarding treatment.
