Calcium and Phosphorus Content of Plaque and Saliva in Relation to Dental Caries

Abstract

Plaque and saliva samples were obtained from 55 children aged 13–15 years: 23 of them were caries free (group N) while the other 32 had evidence of high-caries activity over the preceding 2 years, with a mean DMFS of 25.9 (group H). The average concentration of calcium in posterior plaque of children in group N was 3.57 μg/mg (dry weight), compared with 1.63 μg/mg for group H. The average concentration of calcium in anterior plaque was 11.55 μg/mg in group N and 2.57 μg/mg in group H. The differences between groups N and H were statistically significant (p < 0.01). Similar significant differences were found between phosphorus levels in plaque. Although the mean levels of both calcium and phosphorus in saliva were higher for group N than for group H, only for phosphorus did the difference reach statistical significance (p < 0.05). The present study therefore shows that levels of both calcium and phosphorus are significantly higher in plaque taken from children with no caries experience than they are in plaque from children who are caries susceptible.

Factores salivales asociados a prevalencia e incremento de caries dental en escolares rurales

“…Entre estos últimos, existen componentes de naturaleza proteica de tipo inmunológico (IgA) o no (lisozima, lactoferrina, sialoperoxidasas, proteínas con actividad aglutinante y proteínas ricas en prolina, estaterina) cuyas concentraciones en la cavidad bucal podrían infl uir en la resistencia o susceptibilidad a la caries dental. 4 Respecto a los componentes salivales inorgánicos, Shaw et al 24 informaron la presencia de altas concentraciones de calcio (Ca) y fosfato (P) en sujetos libres ABSTRACT OBJECTIVE: To evaluate the association between saliva and prevalence of dental caries.…”

“…Thus, the availability of calcium in plaque provides a natural anticaries protective effect, either by suppression of demineralization promoted by fermentative acids in mouth, through an increased remineralization by binding calcium ions to teeth enamel, or possibly a combination of both. An inverse relation between plaque calcium and caries incidence has been evidenced [124][125]. [126] has demonstrated that CPP-ACP can actually remineralize subsurface lesions in human enamel, and this is indeed the basis of one claim of his patent [127].…”
