Contraindications; System Specifications - Ultradent Gemini EVO 810 Bedienungsanleitung

GENERAL SAFETY CONSIDERATIONS
• If performing a non-surgical procedure, use an un-initiated fiber tip.
• If performing a surgical procedure, use an initiated fiber tip.
Adjust the laser power settings as needed to fit the clinical circumstances of the case. The preset procedure settings built into Gemini EVO laser are simply a manufacturer's recommendation. Optimal power
level may vary case by case
CONTRA-INDICATIONS
Exercise caution for general medical conditions that might contra-indicate a local procedure. Such conditions may include allergy to local or topical anesthetics, heart disease, lung disease, bleeding disorders,
and immune system deficiency, or any medical conditions or medications that may contra-indicate use of certain light/laser type sources associated with this device. Medical clearance from patient's physician
is advisable when doubt exists regarding treatment.
The Gemini EVO 810+980 soft tissue laser is not indicated for hard tissue procedures. The Laser is attracted to melanin, hemoglobin, and to some extent, water. Avoid prolonged exposure of the energy
when working in and around the cervical areas of the tooth. Due to the thin layer of enamel in this area, energy may be absorbed by the hemoglobin in the pulp and pulpal hyperemia may occur. Extended
exposure to such energy could cause patient discomfort and even lead to possible pulpal necrosis.
EYE AND SKIN PROTECTION
While the Gemini EVO 810+980 soft tissue laser is in use, doctors, system operators, auxiliary staff, patients, and anyone in the operatory must wear the appropriate safety eyewear that has been designed for
use with the 800-plus nm wavelengths associated with lasers. Eye protection must conform to Specification DIN EN207 Annex II of the Directive 89/686/EEC with optical density of OD+5 for the wavelength
range of 800nm-1000nm.
Nominal Ocular Hazard Distance (NOHD) is the distance from the source of laser emission to the point where it no longer exceeds its Maximum Permissible Exposure (MPE – highest level of laser radiation to
which a person may be exposed without hazardous effects or adverse biological changes in the eyes or skin). The Nominal Hazard Zone (NHZ) is the space within which the level of direct, reflected, or scattered
radiation during normal operation exceeds the appropriate MPEs. The outer limit of the NHZ is equal to the NOHD. The NOHD for persons NOT wearing recommended safety glasses is shown in Table 1 below.

Never point the laser tip directly at the face, eyes, or skin of anyone while emitting energy.
EMERGENCY SHUTDOWN OPTIONS:
Perform any of these actions to terminate laser emissions in the event of a real or perceived emergency:
Press the emergency "STOP" Button. (Figure: 19.1)
Press the "ON/OFF" button. (Figure: 19.2)
Remote interlock open circuit deactivates the Laser. (Remote Interlock switch provided by request) (Figure: 19.3)
Touch the ACTIVE/STBY Guided Touch Interface selection (Figure: 19.4)
Release your foot from the Activation Pedal. (Figure: 19.5)
