Effects of ibuprofen and low-level laser therapy on orthodontic pain by means of the analysis of interleukin 1-beta and substance P levels in the gingival crevicular fluid

What Was Tested

Researchers studied Substance P in this randomized controlled trial publication.

The goal of this study was to compare the effects of ibuprofen and low-level laser therapy in alleviating orthodontic pain observed after elastomeric separator placement (ESP) by means of the analysis of interleukin 1‑beta (IL-1β) and substance P (SP) levels in gingival crevicular fluid (GCF) and visual analog scale (VAS).

Who Took Part

According to the abstract, 60 subjects were involved.

A total of 60 subjects requiring ESP for the banding of maxillary first molars were randomly assigned to the ibuprofen, laser, and control groups.

How the Study Was Run

The design is described as randomized and placebo-controlled.

The subjects were allocated by chance, so the Substance P group and the comparison group should start out alike.

The comparison arm used a placebo, so changes seen with Substance P could be set against what happens without it.

GCF samples were collected immediately after ESP (day 0) and on days 1, 3, and 7.

Pain intensity was evaluated using the VAS immediately after ESP (baseline) and at hours 2 and 6, as well as on days 1, 3, and 7.
