Dental Plaque: Nature, Formation and Effects*. BY IRWIN D. MANDEL,** B.S., D.D.S., NEW YORK, NEW YORK. IN 1897, J. Leon Williams demonstrated in a series of ground sections the presence of a thick felt like mass of microorganisms covering the surface where decay had commenced. He described this mass as "so
Dental plaque is broadly classified based on its position as: a) Supragingival plaque: is found at or above the gingival margin b) Sub gingival plaque: is found below the gingival margin. The process of plaque formation can be divided into three phases: a) Formation of Dental Pellicle b) Initial colonization of bacteria.

The oropharynx is an open ecosystem wherein bacteria are always present; bacteria attempt to colonize in all favorable locations. Most bacteria, however, can only persist after the formation of a biofilm upon desquamation-free surfaces,. i.e., hard substances (tooth and root surfaces, restorative materials, implants
OF DENTAL PLAQUE FORMATION. A.AA. SCHEIE. Department of Oral Biology. Dental Faculty, University of Oslo. Pb 1052, Blindern. N-0316 Oslo, Norway. Adv Dent Res 8(2):246-253, July, 1994. Abstract—Much effort has been placed on elucidating the diverse mechanisms of microbial adhesion to tooth surfaces.
The different regions of plaque are significant to different processes associated with diseases of the teeth and periodontium. • For example, marginal plaque gingivitis. Supragingival plaque and tooth-associated subgingival plaque are critical in calculus formation and root caries. Subgingival plaque soft tissue destruction.
Whereas microbial adhesion to tooth surfaces is a general prerequisite for initiation of plaque formation, microbial multiplication is probably the dominant feature in the build-up of dental plaque. Local environmental factors which influence the establishment and composition of the ultimate plaque community are therefore of
