この横断的研究の目的は,慢性汎発性歯周炎患者および歯周病のない患者における小核およびその他のゲノム損傷マーカーの頻度を通じて染色体異常の発生を調査することであった.全身性慢性歯周炎患者35名と健康な歯周組織の対照被験者30名の剥離歯肉上皮細胞を用いて小核測定を行った。歯周状態を明らかにするために全顎臨床検査を行った。慢性歯周炎群および対照群で観察された微小核を有する細胞の平均数はそれぞれ1.8個(±1.49個)および2.0個(±1.34個)であった。群間の差は有意ではなかった(p=0.574)。対照群と比較して、慢性歯周炎患者では、二核細胞数(p≦0.001)および核形質ブリッジを有する細胞数(p=0.042)の有意な増加が認められた。研究の結果、慢性歯周炎は、健康な歯周組織の人と比較して、歯肉細胞における染色体損傷の高い発生とは関連しないことが示された。
The aim of this cross-sectional study was to investigate the occurrence of chromosomal abnormalities through the frequency of micronuclei and other genomic damage markers in patients with chronic generalized periodontitis and without periodontal disease. Micronucleus assay was performed in exfoliated gingival epithelial cells of 35 patients with generalized chronic periodontitis and 30 control subjects with healthy periodontium. Full mouth clinical examination was performed to define periodontal condition. The mean number of cells with micronuclei observed in chronic periodontitis and control groups was 1.8 (±1.49) and 2.0 (±1.34), respectively. Differences between the groups were not significant (p=0.574). Compared to control subjects, patients with chronic periodontitis showed a significant increase in the number of binucleated cells (p≤0.001) and number of cells with nucleoplasmic bridges (p=0.042). Study results indicated that chronic periodontitis was not associated with higher occurrence of chromosomal damage in gingival cells compared to individuals with healthy periodontium.
