Abstract : 「緒言」歯科の二大疾患として齲蝕と歯周病があげられ, これらの原因としては, Streptococcus mutansやPorphyromonas gingivalisを代表とする細菌が主因であると示されている1,2). 歯科臨床では, 齲蝕や歯周病の主原因である細菌を排除する方法として, セルフケア, プロフェッショナルケアなどの概念により, ブラッシングによる物理的清掃と歯磨材, 洗口剤による化学的清掃といった方法が行われている. 近年, これらの疾患の罹患率は減少傾向にある3)が, 垂直性歯槽骨吸収を伴う局所的に急速に進行する歯周病の問題は, なお未解決の課題として残されている. 歯周病に関して注目すべき原因因子のひとつに, 咬合性因子があげられ1900年代初頭から論争が続いている. Glickman(1955)9-6)は, 咬合性因子のうち外傷性咬合が歯周病の促進因子であるという仮説を提案した.

Abstract : [Abstract] Since the proposition of theory that traumatic occlusion could act as a cofactor in the periodontitis (Glickman 1955), controversial argues has been still prevailed whether traumatic tooth contact contribute to the progression of periodontitis or not, larger because there were no direct evidences between them. In this study, we develop new device, by which it could be possible to analyze tooth contact pattern during bruxism and bio-marker of gingival crevicular fluids, simultaneously. Outer surface was for analyzing tooth contact, inner surface was for trapping crevicular fluids and then visualize crevice lactoferrin (Lf) contents by immunological technique. The device revealed that although incisor-canine (IC) contact group showed board Lf expression in the dentition, incisor-canine-premolar (ICP) and incisor-canine-premolar-molar (ICPM) contact groups indicated more Lf expression in the premolar and molar area than those of IC group. Results of coincidence between the occlusal contacts and the Lf expression demonstrated that coincidence was located in the anterior segment in the IC group, while coincidence was seen in the premolar and molar parts in the cases of ICP and ICPM groups. From these findings, it was concluded that there was somewhat correlation between the occlusal contact during sleep bruxism and the expression of Lf in the gingival crevicular fluid.
