Fermentation of sugar by bacteria in plaque (results in lactate production) causes dental caries (see module 1; Dental Plaque Be Bad for more information on biofilm/plaque formation ). Plaque absorbs calcium and phosphate from saliva for the formation of supragingival calculus and from crevicular fluid for the formation of subgingival calculus. The purpose of the present study was to find out to what extent subgingival plaque formation may be prevented by toothbrushing. The experiment was carried out on a total of 28 molars in four monkeys.

Subgingival plaque biofilm can only be seen when it is removed from the pocket with an instrument. We observed recently that strains of Fusobacterium nucleatum also interacted with S. sanguis to form corncobs. Since the fusobacteria are among the first anaerobic filaments to colonize subgingival plaque, these interactions could serve as a connecting link between the transformation of supra- to subgingival plaque. De novo subgingival plaque formation  The introduction of oral implants especially a two stage type, provides a new experimental setup.  Oral implants have been used as a model to study the impact of surface roughness on subgingival plaque formation, smooth abutments (avg roughness < 0.2µm) were found to harbour 25 times less bacteria than the rough ones, with a higher density of coccoid cells.

Plaque formation at ultrastructural level. Pellicle.

This formation, also known as tartar, is a calcified mass that adheres to your teeth. Calculus is classified as either supragingival or subgingival, depending on its location on your teeth. The purpose of this study was to investigate the mode of subgingival plaque formation and its association with various microflora in the thoroughly debrided periodontal pocket by scanning electronmicroscopy. Eleven Periodontally involved teeth with an avarage pocket depth of 6 mm, were selected. Supragingival and Subgingival Plaque and Calculus Formation in Humans †.

Subgingival plaque formation

It occurs after the formation of the supragingival biofilm by a downward growth of the bacteria from above the gums to below. This plaque is mostly made up of anaerobic bacteria, meaning that these bacteria will only survive if there is no oxygen. Supragingival calculus formation is most abundant on the buccal (cheek) surfaces of the maxillary (upper jaw) molars and on the lingual (tongue) surfaces of the mandibular (lower jaw) incisors. These areas experience high salivary flow because of their proximity to the parotid and sublingual salivary glands. 37.

None of the subjects had taken antibiotics or undergone scaling or root planing within the 6 months before the study.
