Periodontal health plays a significant role in the durability of prosthodontic restorations.The margin of discrepancy leads to enhanced buildup of dental biofilm, microleakage, hypersensitivity, margin discoloration, increased gingival crevicular fluid flow (GCF), recurrent caries, pulp infection and, finally, periodontal lesion and bone loss, which can lead to failure of prosthetic treatment.The aim of this study was to evaluate the oral hygiene of patients having various types of fixed prosthesis.Overall level of oral hygiene among patients with fixed prostheis was moderate. Age had a slight impact on oral hygiene, whereas type of prosthesis had a more significant impact on oral hygiene.
