DE and composite cervical restorations on the central incisors; used composite veneers were present on the lateral incisors. DE could not be evaluated on other maxillary teeth because they were all recovered by metal-ceramic FPD: an FPD on 13, 15 and 17 restoring the missing 14,16 and an extended FPD on 23 and 27 with intermediary for 24, 25, 26 (Fig. 1). A metal-ceramic FPD was found on 44, 45, 47 restoring the 46 missing tooth (Fig 1). Maxillary central incisors margins and buccal faces are affected by DE, resulting in important tooth wear with shape and color modifications (Fig. 1).
