ISSN 0906-6713 The role of local factors i the n etiology of periodontal diseases KENNETHS. KORNMAN& HARALD LOE Early concepts of periodontal disease were derived primarily from histopathological observations. Prominent pathologists interpreted the histopathology in various ways and produced somewhat divergent theories on the nature and causes of periodontitis (see Loe in this volume). Some scientists contended that periodontitis was the result of trauma from occlusion that produced excessive forces on the connective tissue and bone. Others believed that the disease had a systemic origin and was closely linked with systemic diseases. Some argued that certain forms of periodontitis were degenerative in nature and were therefore similar to other degenerative processes in the body. And for thousands of years, Egyptian, Hebrew and Chinese writings had spoken of individuals who were âlong of toothâ as a reference to individuals of old age. Some therefore argued that periodontitis was a natural consequence of aging. The accumulations of hard and soft material, including microorganisms, on tooth surfaces had been associated with periodontal disease for many years and, beginning in the late 1800s, various periodontologists and microbiologists contended that parasites, protozoa, streptococci, spirochetes and certain black-pigmented anaerobes were responsible for periodontal disease.
