    Additional Manufacturer Narrative · 1

    THE DENTAL OFFICE REPORTED THAT THREE EVENTS OCCURRED WITHIN A 2-DAY PERIOD USING THE SAME LAVA C.O.S DEVICE. THEREFORE, THREE REPORTS ARE BEING SUBMITTED AND THIS REPORT IS RELATED TO MFR REPORT# 3005174370-2011-00002 AND 3005174370-2011-00003. AFTER EQUIPMENT INSTALLATION AND DURING 3MS OFFICIAL CERTIFICATION TRAINING OF THE DENTIST, THE DENTIST USED THE LAVA C.O.S TO PERFORM A SCAN OF AN ASSISTANT. DURING THE SCANNING PROCEDURE, THE DENTIST STATED THAT HE FELT A PALPABLE CURRENT WHEN HOLDING THE TIP OF THE WAND ON HIS PALM. A MILD SHOCK OCCURRED TO THE ASSISTANT WHEN THE DENTIST TOUCHED THE ASSISTANT'S TEETH WITH HIS FINGER; BUT THE DENTIST DID NOT FEEL THE SHOCK HIMSELF. SERIAL NUMBER (B)(4) REFERS TO THE UNIQUE SERIAL NUMBER OF THE SCANNING WAND COMPONENT OF THE LAVA C.O.S DEVICE WITH A MFR DATE OF 04/2010. METHOD: AN ELECTRICAL SAFETY CHECK IN THE DENTAL OFFICE REVEALED THAT THERE WAS A ELECTRICAL POTENTIAL BETWEEN THE NEUTRAL LINE AND THE PROTECTIVE EARTH ON EVERY POWER OUTLET THE LAVA C.O.S DEVICE WAS CONNECTED TO (RANGING FROM 0.9V TO 18V) AND THE VOLTAGE WAS STABLE. ALSO, AN INITIAL CHECK OF THE ELECTRICAL SAFETY OF THE DEVICE WAS CHECKED IN THE OFFICE-THE LAVA C.O.S DEVICE MET ITS ELECTRICAL SAFETY SPECIFICATION. SUBSEQUENTLY, THE LAVA C.O.S DEVICE WAS RETURNED TO 3M ESPE AND WAS VISUALLY INSPECTED AND ELECTRICALLY TESTED. OTHER REMARKS: VISUAL INSPECTION OF THE WAND SHOWED A SMALL GAP BETWEEN THE PLASTIC HOUSING AND THE METAL TIP OF THE WAND. HOWEVER, ELECTRICAL TESTING CONFIRMED THE DEVICE MET ALL ELECTRICAL SPECIFICATIONS. THE 3M ESPE REVIEWED THE EXISTING USER MANUAL; IT INSTRUCTS THE USER TO EXAMINE THE WAND AND THE SYSTEM (CART, SCREEN, ETC.) FOR PHYSICAL DAMAGE BEFORE EACH USE AND TO CONTACT CUSTOMER SUPPORT IF THERE IS VISIBLE DAMAGE. HOWEVER, ELECTRICAL TESTING CONFIRMED THE DEVICE MET ALL ELECTRICAL SPECIFICATIONS. CONCLUSIONS: AT THIS TIME 3M ESPE CONCLUDES THAT THE LAVA C.O.S DEVICE ITSELF DID NOT CAUSE THE ELECTRICAL SHOCKS BUT ACTED AS A CONDUCTOR FROM A DEFECTIVE SOCKET. THE 3M ESPE CONTINUED TO INVESTIGATE THIS EVENT AND WILL PROVIDE SUPPLEMENTAL REPORTS, AS APPROPRIATE.
