From: Hyaluronic acid skin booster injection and cold laser therapy in oral wounds: an experimental study
Figure 1. Study Design Flowchart. This in vivo experimental study was conducted using 24 Wistar rats, randomly allocated into four groups. Group 1 received a scalpel incision followed by the application of hyaluronic acid and cold laser treatment. Group 2 underwent a 976 nm diode laser incision with hyaluronic acid and cold laser treatment. Groups 3 and 4 served as control groups, with group 3 receiving a scalpel incision and group 4 undergoing a 976 nm diode laser incision. Biopsy samples were collected at baseline, postoperative day 3, and postoperative day 7 for histological analysis.
