A 45 year old female patient returns to your clinic with complaint of food lodgement in interproximal area of 47. On intraoral examination, 47 is restored with disto-occlusal amalgam restoration. What can be the most probable reason for this patient’s problem?
Correct Answer: Contact area placed more occlusally
Description: Proximal surface restorations often display an occlusogingival proximal contour that is too straight, thereby causing the contact relationship to be located too far occlusally (with little or no occlusal embrasure). This condition allows food impaction betwee teeth with resultant injury to the interproximal gingiva and supporting tissues and invites caries.
