The effects of occluding dysfunction on marginal parodontopathies

: Occluding dysfunction (occluding dysharmony, occluding trauma) is an important etiologic factor of parodontal disease. It is an integrating element of the destructive process which characterizes the parodontal disease. Occluding dysfunction does not trigger gingivitis, or the development of parodontal pouches, but it does exert an influence on the progress and the importance of parodontal pouches determined by local irritation due to tartar and to bacterial plaques. Occluding dysfunction and the inflammation of parodontal tissues are different processes which occur in the course of the same disease namely of marginal parodonthitis. The inflammation develops in the gums and propagates in the parodontal sustaining tissues. Occluding dysfunction (also known as occluding dysharmony or occluding trauma) occurs in the parodontal sustaining tissues, and both determine tissue destruction. Occluding dysfunction and inflammation become codestructive factors which are interconnected, and are both capable to determine clinical and radiologic changes which are typical for diseased marginal parodontium. Due to the fact that individuals have variable parodontal reactions to local irritation factors, and considering the fact that inflammation and occluding dysfunction occur together but with variable degrees of severity, it is possible that they will not determine in all cases intraosseus pouches with angular lesions, or crater-like lesions. However, when we are confronted with such lesions it is very likely that the combined effects of inflammation and occluding dysfunction are at the origin.
