three weeks after delivery of a unilateral distal extension mandibular removable partial denture, a pt complained of a sensitive abutment tooth, clinical examination reveals sensitivity to percussion of the tooth, the most likely cause is:
***a-defective occlusion
b- exposed dentine at the bottom of the occlusal rest seats
c- galvanic action between the framework and an amalgam restoration restoration in the abutment tooth
