Due to a deviation one patient in the Sham group had toothpick samples collected at 7 weeks instead of the intended 8-week collection timepoint.

IAN function for hard stimuli was assessed by pressing a toothpick into the skin of the mandible and lower lip in 8 regions along the lower jaw. Regions right and left 1, 2, and 3 are on the skin of the lower face, 1 cm apart, starting on the midline, and right and left region 4 is the lower lip, separated at the midline. Right and left regions were abbreviated as R1, R2, R3, R4 and L1, L2, L3, and L4, respectively. Patients responded as to whether they were able to feel the toothpick using a binary Yes (+) or No (-) response. The number of patients who responded Yes (+) is summarized by study arm.

Study was terminated in advance of the 20-week timepoint and toothpick samples were not collected from any of the participants at 20 weeks post-surgery. Accordingly, there are no IAN function for hard stimuli results to report.

Post-operative pain was assessed and reported during each study visit using a single-item Visual Analog Scale (VAS) question. Patients rated the intensity of pain on each side of the mandible (right and left) on an 11-point Likert scale. Possible VAS scores ranged from 0 (complete absence of pain) to 10 (maximum amount of pain imaginable). Results were summarized by study arm using basic descriptive statistics.

24-hour post-surgical follow-up visits were not conducted during this study. Many patients were still admitted at 24 hours post-procedure and were unable to be brought into the dental clinic. In addition, the instruments and equipment required to conduct this assessment were not available in the hospital in-patient rooms. As a result, VAS scores were not obtained from any of the patients at 24 hours post-surgery and there are no post-operative pain results data to report.
