Device Story
PerioLase Nd:YAG Pulsed Dental Laser System uses flashlamp-pulsed Nd:YAG rod in optical resonant cavity; energy/pulse width controlled by microprocessor-based flashlamp switching circuit. Device delivers laser energy via contact fiber-optic cable to soft tissue for ablation, incision, vaporization, and coagulation. Operator controls parameters (energy, pulse width, repetition rate) via touch screen; internal energy monitor provides feedback to microcontroller for adjustments. System includes independent watchdog microprocessor for safety monitoring and interlocks. Used in clinical settings by dental/surgical professionals. Output allows for precise soft tissue management, sulcular debridement, and periodontal regeneration (LANAP protocol). Benefits include improved clinical indices (probe depth, attachment level) and potential for true periodontal regeneration of cementum, ligament, and alveolar bone.
Clinical Evidence
Prospective human histological study (n=12 teeth from 8 patients) evaluated periodontal regeneration using LANAP protocol. Primary endpoint: histological evidence of new cementum, periodontal ligament, and alveolar bone coronal to a root notch. Results: 5 of 10 evaluable sites (50%) demonstrated true periodontal regeneration; 4 sites healed via long junctional epithelium; 1 site showed new cementum/reattachment. Study supports clinical claim of periodontal regeneration.

### 3. Device Description:
PerioLase Nd:YAG Pulsed Dental Laser System (same as K010771, K014272, and K030290)
The laser head consists of a flashlamp-pulsed Nd:YAG rod in an optical resonant cavity. The energy and the width of each laser pulse are determined by the size and shape of the current pulse through the flashlamp. The current pulse through the flashlamp is controlled by the flashlamp switching circuit. This circuit is based on a solid-state switch that sets the current level and pulse width according to the microprocessor controller. The rate at which the laser pulses are produced, the repetition rate or the pulses/second, is also determined by the microprocessorcontrolled switching circuit. The output energy of each laser pulse is measured by
{5}------------------------------------------------
the internal energy monitor. This value is compared to the energy setting by the microcontroller and adjustments are made if necessary.
The laser beam emitted from the laser head is coupled into a fiber-optic cable at the fiber port. The presence of the fiber-optic cable is detected by a sensor such that the laser will not fire if the fiber-optic cable is not in place. The laser aperture is at the distal tip of the fiber. The laser head is cooled by circulating water whose excess heat is removed by an air-water heat exchanger.
The operator controls the laser through the touch screen display. The microcontroller handles all of the logic required to set the energy levels, pulse widths, and repetition rates for the laser output, monitors the output pulses to assure proper output energy, monitors all of the interlocks and sensors, and checks for proper operation of the switches, power supplies, and cooling system. Proper operation of the microcontroller is checked by an independent watchdog microprocessor. The system is designed such that no single fault can result in a system failure.
All of the requirements of the laser safety standards of the CDRH as well as of the IEC 60825-1 standard are incorporated, including the remote interlock connector, the laser stop button, the key control, and the safety and manufacturers labels.

## 5. Summary of a Comparison of Technological Characteristics:
The comparison table provided in the Substantial Equivalence Comparison section of this submission establishes the basis for the determination of substantial equivalence of the PerioLase Nd:YAG Pulsed Dental Laser System to its named predicate device.
The PerioLase Nd:YAG Pulsed Dental Laser System has the identical wavelength, laser medium, beam delivery system type (optical fiber), laser activation method (footswitch), power source (conventional AC power), type of aiming beam and cooling system, and intended uses as its named predicate device.
The PerioLase Nd:YAG Pulsed Dental Laser System's power, pulse duration, energy per pulse, and repetition rate are identical to its named predicate device. There are no differences between the subject and predicate with respect to technology.
## 6. Nonclinical Performance Data:
The PerioLase Nd:YAG Pulsed Dental Laser System has been evaluated via verification and validation tests and inspections for conformance to applicable regulations and safety standards. Each PerioLase is tested for electrical safety and output characteristics to ensure it meets the design criteria for essential performance, its safety features and functions operate correctly, and it satisfies the performance requirements specified in 21 CFR 1010 and 21 CFR 1040.
{7}------------------------------------------------
Representative data is presented in the Performance section and accompanying appendix of this submission.
#### 7. Clinical Performance Data:
Periodontitis is an infectious disease that progressively destroys the alveolar bone, the periodontal ligament, and the root cementum that attach the teeth to the bone. Destruction of this attachment apparatus results in the loss of teeth. The ultimate aim of periodontal regeneration techniques is to induce or guide healing to regenerate the morphology back to its original configuration. In order to evaluate a regeneration technique experimentally, a notch is made on the root surface at the bottom of a periodontal pocket to provide a histological landmark for the apical extent of the destruction. True periodontal regeneration is then defined by histological evidence of new bone, periodontal ligament, and cementum appearing above the notch on a previously diseased root surface.
Results of a prospective human histological study provide evidence of true periodontal regeneration with new cementum, periodontal ligament, and alveolar bone on previously diseased root surfaces in patients treated nine months earlier with the LANAP® protocol using the PerioLase Nd:YAG Pulsed Dental Laser System.
Eight patients treated with the LANAP® protocol using the PerioLase Nd:YAG laser provided twelve treated teeth that were scheduled for extraction. After nine months of healing, en bloc biopsy extractions were evaluated histologically to assess periodontal wound healing.
Two teeth splintered during histological preparation and were not available for microscopic evaluation. Four teeth healed via long junctional epithelium and one tooth demonstrated new cementum and reattachment apical to the notch.
Five of the remaining ten sites (50%) healed coronal to the notch with true periodontal regeneration, demonstrating new cementum, new periodontal ligament, and new alveolar bone with inserting Sharpey's fibers forming functional reattachments.
Three teeth demonstrating regeneration coronal to the notch also presented with loss of attachment within furcations. These areas demonstrated new bone, new ligament, and new cementum as well.
#### 8. Conclusions:
The PerioLase Nd:YAG Pulsed Dental Laser System is substantially equivalent to the predicate device in technical characteristics, design features, operating principles, functional and performance characteristics, and for the intended uses in the stated medical specialties. The PerioLase is designed to comply with applicable federal and international safety and performance standards. Histologic data support the new clinical outcome claim. There are no new safety and effectiveness issues.
