A mineral-related feature of young plaque characteristic to periodontitis-affected adults.
The calcium concentration of 3-day-old total supragingival plaque in periodontitis-affected adults (n = 12) and their age and sex-matched periodontitis-free pairs was compared. The young plaque of the periodontitis-affected adults contained more calcium per protein (P less than 0.025, sign test) than that of the periodontitis-free pairs. The findings of the present study may suggest that high Ca-content of supragingival plaque is connected to the development of adult periodontitis.
