A combined laser and ultrasonic device includes a combination laser and ultrasonic source, a control console and a combined laser and ultrasonic delivery handpiece. The system has three modes of operation: 1) laser energy only, 2) ultrasonic energy only and 3) combined laser and ultrasonic energy. All three modes of operation are controlled by a single foot-operated activation switch, which will operate the laser source, the ultrasonic source or both, depending on which mode the device is operating in according to a mode switch on the control console. The combined laser and ultrasonic delivery handpiece includes an ultrasonic transducer coupled to an ultrasonic vibrating tip, which is mounted in close proximity to a laser delivery wave guide, such as a flexible optical fiber. The combined laser and ultrasonic device can be used to perform a variety of surgical procedures, including an improved method of a laser excisional new attachment procedure (Laser E. N. A. P. ), which is described for treatment of periodontal diseases.

A reusable connector adapter for coupling any fiber optic transmittable laser source to a fiber optic laser delivery device, the laser source having a laser energy output port. The adapter allows the use of a variety of different laser sources with a variety of different fiber optic laser delivery devices. The adapter maintains the fiber optic laser delivery device adjacent to the laser energy output port such that the laser energy to be transmitted is communicated efficiently to the fiber optic laser delivery device. The adapter further comprises a laser interlock deactivation means such that if a laser source has a mechanical, electrical or optical interlock system, the adapter will function to deactivate the interlock system. Furthermore, the adapter also comprises a plurality of optical barriers to prevent the unintended transmission of laser energy when, for example, the fiber optic laser delivery device has not been installed or has not been installed properly.
