  • Takayasu's arteritis 환자의 치과 치료 시 침습적인 치과 술식 전 심내막염 가능성을 고려하여 예방적 항생제를 투여한다. 복용 약물에 의해 치은증식이 발생할 수 있으므로 약물의 적용에 관한 의과적 자문이 필요하다.

  • The purpose of this study was to investigate the differences of histochemical characteristics in inflammatory fibrous gingival hyperplasia (FGH), phenytoin-induced gingival hyperplasia(PIGH), idiopathic gingival hyperplasia(IDGH) and control groups (healthy and inflammatory gingiva) by immunohistochemical method with various antibodies and histomorphological analysis. In immunohistochemical finding, antibodies to inflammatory cells (T/B lymphocytes, macrophages, other monocytes), proliferating cell nuclear antigen(PCNA), epidermal growth factor(EGF), factor VIII, and type I collagen were used. 1. The inflammatory infiltrates in FGH were less than those in inflammatory gingiva. The composition of inflammatory cells of PIGH was similar with that of FGH. IDGH showed a similar histologic findings with healthy gingival tissue. 2. In FGH, the number of fibroblasts and newly-formed collagen fibers was increased. No significant increase of fibroblasts and the dense accumulation of thick collagen fibers were seen in PIGH. The increase of fibroblasts and the dense accumulation of thick collagen were seen in IDGH. 3. PCNA-positive cells were localized mainly in the area accumulated with inflammatory cells and blood vessels, significantly increased in all hyperplastic tissue groups, and distributed evenly in IDGH. 4. The distribution of EGF were not observed in healthy gingiva but detected locally in area with confluent blood vessels,without significant difference between the other tissue groups. This results suggest that inflammation plays a significant role in inducing hyperplastic change of gingival tissue. While in DIGH, drug itself as well as inflammation seems to attribute to hyperplastic change.

  • Amlodipine, nifedipine, and felodipine are calcium channel blocking agents, which are cause of unwanted gingival overgrowth around natural teeth. Many studies has been performed about this unwanted effects. However, the exact etiology remains uncertain.Few reports and investigations can be found in the literature on drug-induced gingival overgrowth around dental implants. The present case reports that amlodipine-induced gingival overgrowth occurred in peri-implant sites, confirms clinical and histological features in hyperplastic peri-implant tissues. Clinical and histological features of amlodipine-induced gingival overgrowth around dental implants were similar to that of tissue around natural teeth.

  • Gingiva is remarkly sensitive to certain drugs. Especially, long term use of phentoin, dihydropyrydine (including nifedipine), cyclosporin and other drugs can be lead to pathologic changes in gingival tissue, especially in terms of proliferation of epithelium and connective tissue. Recent study in terms of proliferation of epithelium and connective tissue. Recent study is focused on the inhibition of drug-induced gingival hyperplasia by using medicaments. The purpose of this study was to investigate on the pharmacological effects of nifedipine, retinoic acid and glycyrrhetini acid to the activity in human gingival fibroblast. Human gingival fibroblasts were cultured from the healthy gingiva of orthodontic patients. Gingival fibroblasts were trypsinized and cultured in growth medium added $5{\mu}g/ml$ of nifedipine, $10^{+7}M$ of retinoic acid and glycyrrhetinic acid. The passage number of cultured fibroblasts were between fifth and eighth. The cell morphology was examined by inverted microscope and the cell acitivity was measured by the MTT assay. Nifedipine at the concentration of $5{\mu}g/ml$ was revealed significantly effective to increase the cell activity and lipopolysaccharide was cofactor to increase cell activity in the presence of nifedipine. However, retinoic acid was significantly effective on the globular change of cell morphology and loss of cell process regardless of the presence of nifedipine and LPS. Cell activity was significantly decreased by the glycyrrhetinic acid at the concentration of $10^-M$ regardless of the presence of nifedipine and LPS. These results suggested that the increased cell activity by nifedipine might be modulated by retinoic acid and glycyrrhetinic acid. Further study is needed to clarify on their toxicological effects during cellular modulation and mRNA expression change.
