Summary of "Humic Acid, a Polyphenolic Substance, Decreases Alveolar Bone Loss in Experimental Periodontitis in Rats."

The purpose of this study was to evaluate the biochemical, morphometric, and histopathological changes associated with experimental periodontitis in rats in response to local administration of humic acid. Thirty-eight Wistar rats were divided into 5 experimental groups: nonligated (NL) group, ligature-only (LO) group, and ligature + local administration of humic acid (20, 80, and 150 mg/kg body weight per day for 15 days, respectively; L-20, L-80, and L-150 groups). Changes in alveolar bone levels were clinically measured as the distance from the cementoenamel junction to the alveolar bone crest with a stereomicroscope. Tissues were histopathologically examined to assess the osteoclast numbers, osteoblastic activity, and inflammatory cell infiltration among the study groups. Enzyme-linked immunosorbent assay interleukin1β (IL-1β) and IL-10 levels in serum and gingival homogenates were evaluated. At the end of 15 days, the alveolar bone loss was significantly higher in the LO group compared to the NL, L-20, and L-150 groups ( < .05). The osteoclast number in the LO group was significantly higher than the NL, L-20, and L-150 groups ( < .05). Inflammatory cell infiltration was significantly higher in the LO and L-80 groups than the other groups ( < .05). The highest serum and gingival homogenate IL-10 levels were determined in the NL group ( < .05). The serum and gingival homogenate IL-1β levels in LO group were significantly higher than the NL, L-20, and L-150 groups ( < .05). Within the limits of this study, it can be suggested that humic acid, when administered locally at 20 and 80 mg/kg doses, may prevent alveolar bone loss in the rat model.
