  1. 1Vital = the tooth was diagnosed with either normal pulp or pulpitis, Non-vital = the pulp was necrotic; 2categorized as ‘normal’ or ‘with periapical pathology; 3M-D = mesio-distal, B-L = buccolingual; 4present = both adjacent teeth were present; 5extensive restoration=the restoration covered two or more of the tooth crown aspects, but not the whole crown, minor restoration = the restoration covered one aspect of the tooth crown; 6deep periodontal pocket = probing depth >4 mm; 7In cases where the evaluated parameters were not available from the patients’ medical records, the results were presented as a percentage from the number of cases in which that parameter was available; *P < 0.05.
