The observed phase transition temperatures were indeed independent, within the experimental uncertainty, of the laser pulse power and duration, whereas, of course, longer and more powerful laser pulses implied higher peak temperature, longer dwelling time beyond melting, larger vapour production etc
Example experimental endpoints: healing rate (time to closure), expression of repair markers (e.g., collagen I/III ratio), and functional recovery assays
Initially, three patients in the loading dose group and seven in the no loading dose group had GDS scores 5, decreasing to two patients in each group by study end
Evans blue concentration was determined by spectrophotometric measurement at 620 nm and expressed as g/g gingivomucosal tissue as described earlier by our group (6)
