You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

for use of the subject device are the same as for the predicate device CuringPen Dental Curing Light(K221152), except that the CuringPen Dental Curing Light has a wavelength range of 380-515nm per ISO 10650:2018 while the subject device(M-Cure 6), has a wavelength range of 385-515nm, but same with the reference device D-Lux+(K200809) with wavelength range of 385-515nm. **The difference does not raise new question of safety and effectiveness.** | | --- | --- | | **D2:** | The subject device is handpiece type using an internal rechargeable lithium ion battery, which is the same as the predicate device CuringPen Dental Curing Light(K221152). The battery power of subject device is similar with predicate device, the subject device can work normally and meet the performance including Light Intensity, Depth of cure under battery power. So the difference doesn't raise new questions of safety and effectiveness. | | **D3:** | 1.The subject device M-Cure 6 has same Standard mode and PULSE mode with the predicate device CuringPen Dental Curing Light(K221152). 2.The subject device has a **Caries checking mode**, which is functionally equivalent to the **Detect mode** of the predicate device CuringPen Dental Curing Light(K221152). Both are non-curing modes intended for diagnostic purposes. 3. The subject device M-Cure 6 has a Soft mode, while the predicate device has a RAMP mode. Both modes are designed to gradually increase light intensity. And M-Cure 6 has same Soft mode with the reference device D-Lux+(K200809). | 9 / 14 {13} | | 4. The Fast curing mode of the subject device is functionally equivalent to the MAX (Max Power) mode of the reference device D-Lux+. Both names indicate a mode that provides high-intensity, continuous light output for rapid curing. 5. The subject device M-Cure 6 has Ortho mode, which are same as ORT (Orthodontic) mode of the reference device D-Lux+(K200809). Therefore, the difference does not raise new question of safety and effectiveness. | | --- | --- | | **D4:** | The subject device has Adapter, Bracket, and Light hood, while the predicate device CuringPen Dental Curing Light(K221152) has Charging base, Protective light shield, Adapter, Disposable sleeves (1x100pcs), User Manual. The bracket of the subject device is used for holding the device during battery charging, Light hood of the subject device is used to protect dentists from hurting eyes, which have the same functions with charging base, protective light shield of the predicate device CuringPen Dental Curing Light respectively The accessories of the subject device are covered in the predicate device; therefore, the difference does not raise new question of safety and effectiveness. | | **D5:** | The subject device uses disposable isolation sleeve to prevent cross infection of the patient, which has the same function with the predicate device CuringPen Dental Curing Light(K221152) using the disposable sleeve. The difference does not raise new question of safety and effectiveness. | | **D6:** | As the subject device uses disposable isolation sleeve to prevent cross infection of the patient, the disposable isolation sleeve contacts with patient, while Disposable-Sheaths of primary devices use contacts with patient. The disposable isolation sleeve of subject device has cleared 510K. Therefore, the difference does not raise new question of safety and effectiveness. | 10 / 14 {14} | **D7:** | 1. Light Intensity of the subject device M-Cure 6 for standard mode(M1, M2, M3 mode,1000, 1500, 2300mW/cm²),soft mode(1000 mW/cm²), pulse mode(1000 mW/cm²) and caries checking mode(600 mW/cm²), are same with those of the predicate device CuringPen Dental Curing Light(K221152). 2. Light Intensity of the subject device M-Cure 6 for Ortho mode(1800 mW/cm²) is same with the reference device D-Lux+(K200809). 3. Light Intensity of the subject device M-Cure 6 for Fast curing mode(2500 mW/cm²) is a little larger than MAX (Max Power) mode(2400 mW/cm²) of the reference device D-Lux+(K200809), but same with the reference device LOOP LED Curing Light System(K200775). Therefore, the difference does not raise new question of safety and effectiveness. | | --- | --- | 11 / 14 {15} ## 8.
