Additional Manufacturer Narrative · 1

PATIENT SPECIFIC INFORMATION WITH REGARD TO GENDER, AGE AND WEIGHT WAS NOT PROVIDED. ALTHOUGH THE DOCTOR IDENTIFIED TWO (2) DIFFERENT LOTS ASSOCIATED WITH THE LOSS OF A CROWN, SHE COULD NOT VERIFY WHICH LOT WAS USED ON EACH PATIENT; THEREFORE, NO LOT NUMBERS WERE IDENTIFIED IN THIS REPORT. THE LOTS INVOLVED IN THE ALLEGED INCIDENTS INCLUDE LOT NUMBERS 4810518 AND 4884702. THE DOCTOR RE-CEMENTED THE CROWN FOR THE PATIENT USING THE SAME PRODUCTS WITHOUT FURTHER INCIDENT. TO DATE, THE PATIENT IS DOING FINE. THE PRODUCTS ALLEGED IN THIS INCIDENT WERE NOT RETURNED; THEREFORE, 'ADHESIVE STRENGTH' TEST OF THE RETAINED SAMPLES WERE EVALUATED YIELDING RESULTS WITHIN SPECIFICATIONS. A DHR REVIEW REVEALED THAT THERE WERE NO DEVIATIONS FROM THE MANUFACTURING PROCESS. IN ADDITION, NO SIMILAR COMPLAINTS WERE RECEIVED WITH REGARD TO LOTS 4810518 AND 4884702.
