Table 4.
Percentiles for oligoelements involved in metabolic functions in patients with long-term titanium implant and dental fillings after 90 days of supplementation (d90, n = 16) and their basal levels (d0: before any supplementation, n = 16) and non-supplemented controls (control: without dental materials and non-supplemented, n = 21). All heavy oligoelements were expressed as μg g/g of hair.
