Effects of local irritation and dextran sulphate administration on the periodontium of the rat

Abstract: Local irritation, provided by means of silk ligatures at the necks of mandibular first molars of rats, caused significant resorption of crestal alveolar bone. This resorption did not change significantly in extent from 27 days after placement of the ligatures. However, in rats receiving injections of dextran sulphate, there was no significant reduction in height of crestal alveolar bone of non‐ligated mandibular first molars. The injections of dextran sulphate caused the appearance of large numbers of multinuc… Show more

“…The groups with ligature around the mandibular right first molar 11 had an initial gingival lesion, and this fact provoked the dilatation of the microvascular net of the region, with an increase in the hydrostatic pressure and fluid permeability, and also in the displacement of the leucocytes to the crevicular gingival fluid; cell response had been well established between two and four days. In this study, the group treated with meloxicam did not show results statistically different from the group not treated with meloxicam when the treatment was performed for 15 days (groups VII and VIII (p > 0.05)).…”

“…Thus, the activation of other inflammatory mediators can be explained by the absence of the inhibition of bone resorption found in the groups treated with meloxicam in the available periods 11 . Meloxicam and other NSAIDs may be considered promising agents in the treatment of periodontal disease, but other studies may be necessary and should be idealized to explore the various aspects that are not yet elucidated.…”
