ABSTRACT

<p><b>OBJECTIVE</b>To observe the effect of the IgY solution on dental plaque and mutans Streptococci in plaque and in saliva.</p><p><b>METHODS</b>A double-blind study was used. 44 school children at the third grade in test group used the IgY solution for 21 days; 41 children in control group used the placebo. The plaque index, the plaque weight, the level of mutans streptococci in saliva and in plaque were tested for all children.</p><p><b>RESULTS</b>The plaque weight in test group was (46.4 +/- 31.2) mg at baseline, and (36.6 +/- 25.6) mg at the end of the study (P = 0.007). The IgY solution reduced 21.1% plaque weight. Statistically significant differences for other indices were not shown in this study.</p><p><b>CONCLUSION</b>The 0.1% IgY solution reduces the mass of plaque on the tooth surfaces.</p>
