No
The summary describes a laser system for soft tissue procedures and does not mention any AI or ML capabilities.
Yes
The device's intended uses clearly describe medical procedures for treating various conditions and tissues across multiple surgical specialties (e.g., incision, excision, vaporization, ablation, coagulation, hemostasis, removal of lesions, treatment of ulcers). These actions are therapeutic interventions aimed at restoring health or alleviating symptoms.
No
This device is described as a laser system for incision, excision, vaporization, ablation, coagulation, and hemostasis of tissues, which are all therapeutic or surgical functions, not diagnostic ones.
No
The device description explicitly states it is a "dental diode laser system" and describes hardware components like a "Gallium Aluminum Arsenide (GaAIAs) solid state laser diode" and a "flexible fiberoptic handpiece." This indicates it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue samples) taken from the human body to provide information about a person's health. This testing is done outside the body (in vitro).
- Device Function: The description of the Twilight™ dental diode laser system clearly states its function is to "incise, excise, and ablate intraoral soft tissues safely and effectively." It delivers optical energy to the body for surgical procedures.
- Intended Use: The extensive list of intended uses involves direct surgical intervention on various tissues within the body (oral soft tissues, ear, nose, throat, joints, GI tract, skin, etc.). These are all in vivo procedures.
The device is a surgical laser intended for direct treatment of tissues within the body, not for testing samples taken from the body.

Device Description
The Twilight™ dental diode laser system may be used to perform several dental applications. Twilight™ uses advanced laser technology to incise, excise and ablate intraoral soft tissues safely and effectively. A Gallium Aluminum Arsenide (GaAIAs) solid state laser diode provides optical energy to oral soft tissues.
A flexible fiberoptic handpiece delivers the Twilight™ laser energy. A visible light emitted from the handpiece distal end pinpoints the area of treatment. The optical power output and pulse may be adjusted to specific user requirements.

Cautions and Contraindications:
All clinical procedures performed with Twilight™ must be subjected to the same clinical judgement and care as with traditional techniques. 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.
Substantial Equivalence:
There are no unique applications, indications, materials or specifications presented herein. Twilight™ is identical to several other diode laser systems cleared by the FDA. Equivalent devices include: Premier, Aurora™(K954316), American Dental
Technologies, PulseMaster™ (K972325) and Dentek, LD-15 ™ (K974057) for general dental soft tissue applications, Premier, Aurora™ (K981379) for pulpotomy and American Dental Technologies, PulseMaster™ (K961269) and Premier, Aurora™ (K974586) for sulcular debridement.
Conclusion:
Twilight™ is substantially equivalent to several available, established dental diode laser products. Twilight™ performs through the same mechanism as other diode laser technologies.

Dear Ms. Rizoiu:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Ouality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (OS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
