Objective: The purpose of this study was to investigate the periodontal response to the presence of all‐ceramic crowns (IPS Empress) in general practice patients. Methods: The convenience sample included 82 IPS Empress crowns placed in 64 patients. These crowns had been in place for an average of 16.27 (SD 9.26) months and ranged from 6.2 to 48.87 months at the time of clinical examination. Periodontal health status (as determined by dental plaque, gingival health status, periodontal pockets) was assessed around all crowned teeth and around matched contralateral teeth by one calibrated examiner. Periodontal indices utilized included the Plaque Index (PI), Gingival Index (GI) and pocket depth (PD) with calibrated probes graduated in millimetres. Plaque, gingival and PD values for crowned teeth were compared with those for control teeth using Wilcoxon signed‐rank test for each clinical parameters. Chi‐square was used to test the significance of the difference in their distribution between crowns and control teeth. Results: Statistically, PI (0.35), GI (0.41) and mean PD scores (1.42) of IPS Empress crowned teeth compared less favourably with scores of the control teeth (0.27, 0.23 and 0.86 respectively). Conclusion: Teeth with IPS Empress crowns had poorer periodontal health and more clinically evident plaque than uncrowned teeth.
