METHODS
32 female Wistar rats were divided into four experimental groups as; Group 1: healthy control (C, n = 8), group 2: Periodontitis (P, n = 8), group 3: periodontitis and 50 mg/kg VA administered group (P + VA-50, n = 8) and group 4: periodontitis and 100 mg/kg VA delivered group (P + VA-100, n = 8). Ligature-induced experimental periodontitis was carried out at mandibular first molar teeth of the right quadrant by placing submarginal 4-0 silk ligatures. VA was administered by oral gavage for 14 days beginning from the first day. Rats were euthanized on the 15th day. Morphological changes in alveolar bone were evaluated via a stereomicroscope. Mandibles were subjected to histological procedures. Osteoblasts, tartrate-resistant acid phosphatase synthesizing osteoclasts and inflammatory cells were counted. Inducible nitric oxide synthase (iNOS), cluster of differentiation (CD)-68, Matrix metalloproteinase (MMP)-1, tissue inhibitor of MMP-1, runt-related x factor-2 (RUNX2), and cyclooxygenase (COX)-2 expressions were determined by immunohistochemistry.
