“…The results for plaque acids are in agreement with the previously reported range of these acids (17-20.5 nmol/ mg for lactate, 6-12.3 nmol/mg for acetate, and 3-11.0 nmol/mg for propionate) [Distler and Kröncke, 1983;Oliveby et al, 1990;Simone et al, 1992]. The slightly higher concentrations for lactate in the current study are probably caused by the differences in subject population, and the plaque sampling technique.…”

Effect of an Essential Oil Mouthrinse, with and without Fluoride, on Plaque Metabolic Acid Production and pH after a Sucrose Challenge

This clinical study evaluated the effect of rinsing with an essential oil-containing antiseptic mouthrinse, with or without 100 mg/kg fluoride ion, on the plaque metabolic acid production and plaque pH response after a sucrose challenge. This observer-blind, randomized study used a three-way crossover design. Twenty-four subjects rinsed with 20 ml of one of the following rinses: (1) essential oil (EO) mouthrinse, (2) essential oil mouthrinse plus 100 mg/kg fluoride, or (3) negative control, for 30 s, twice daily for 16 days. On day 17, 1 h after the last mouthrinse, subjects rinsed with 20 ml of mass fraction 10% sucrose solution for 1 min. Seven minutes after the sucrose challenge, supragingival plaque was collected from molar and premolar teeth. Plaque pH and metabolic acid ions were analyzed using a micro pH electrode and capillary electrophoresis, respectively. The results showed that after EO mouthrinse dental plaque produced 36% less lactate, 36% less acetate and 44% less propionate than after the negative control rinse. The dental plaque also exhibited a pH 0.42 unit higher after EO rinse than after the negative control rinse. These results were not affected by the addition of 100 mg/kg fluoride to the EO mouthrinse. From these results we concluded that this EO antiseptic mouthrinse, with or without fluoride ion, is effective in reduction of plaque acidogenicity after a sucrose challenge.

“…The acid/anion results from this study are similar to those reported by Geddes [1975], Vratsanos et al [1979] and Distler and Kroncke [1983], who have analysed pooled plaque from fasted subjects before and after sucrose rinsing. In the present study, like those cited above, it was found that the lactic acid exhibited a steep in crease following a sucrose rinse.…”

“…The two meth ods used to test the composition of the de posits which formed on the appliance were acid/anion profile analysis and microbiological assessment. These tests were chosen because the changes in or ganic acid levels of fasted plaque after ex posure to sucrose have been investigated thoroughly [Distler and Kroncke, 1983;Geddes, 1975;Geddes and Weetman, 1983;Gilmour et al, 1976] and the bacte ria normally present in 7-to 9-day-old dental plaque have been well character ised [Ritz, 1967],…”

The microbiological species and acid/anion profiles of the plaque-like material which accumulates on exposed surfaces of enamel sections mounted in the experimental troughs of the previously described in situ caries appliance were studied. Each experiment lasted 1 week and the volunteers’ diet and oral hygiene patterns were unaltered, except that interproximal plaque was allowed to accumulate in an interproximal space adjacent to one of the troughs. The appliance was removed once per day to facilitate cleansing of the lower lingual aspects of the natural dentition. The acid/anion profiles of the appliance samples were similar to plaque of equal maturity from the adjacent interproximal site. Qualitatively the microbiological species recovered from the natural and appliance plaque were similar and within the normal range for 7- to 9-day natural plaque. When the composition of appliance and natural plaque was compared some quantitative differences were found. Thus it would seem that the previously reported de- and remineralisation investigations using this appliance were carried out under the influence of an ecosystem similar to that of an adjacent interproximal site of the natural dentition. In addition, this appliance should provide a means for the study of the microbiology and biochemistry of early enamel caries.

“…Kuhn and Wilson (1985) mentioned that the dissolution of glass-ionomer and silicate cements included three steps: (1) surface wash-off, (2) diffusion in the solid state, and (3) surface corrosion. We reported in our previous article that the dissolution of glass-ionomer cements in an acidic acetate-buffer solution was controlled by the diffusion of species through the cement matrix, and that the elution of species was in proportion to the square root of immersion time.The mouth contains more organic acids than acetic acid (Distler and Kroncke, 1983). We reported that the H' ion concentration and the formation constants for soluble complexes between the acid anions and metal cations in the set cement controlled the degree of the erosion of a glass-ionomer cement in organic-acid solutions (Matsuya et al, 1984).…”

The Mechanism for Erosion of Glass-ionomer Cements in Organic-Acid Buffer Solutions

The behavior and mechanism for erosion of glass-ionomer cements in organic-acid buffer solutions were studied as a function of time, pH, and citric-acid concentration. In acidic solutions, the dissolution of the cement was controlled by the diffusion of the eluted species in the cement matrix, which depended on H+ ion concentration. In citric-acid solutions, the dissolution of the cement was controlled by both the diffusion and the surface reaction between the acid anion and the eluted species. Contribution of the latter reaction was larger with the increase in the acid concentration.
