What is it about?
Haemolysins are from several groups and each group has the potential to act as mechanisms for the bacteria to breach the pocket epithelium and thus invade the tissue. Importantly this study showed that the thicker the plaque, the greater the haemolysis.

Why is it important?
Thus simple plaque removal or reduction would seem to reduce the toxicity of the plaque. An important fact in reducing the ability of plaque to induce periodontal disease.
Perspectives
This paper supports the idea that plaque removal or reduction in volume would be likely to reduce the plaque pathogenicity. Up until now we have looked at plaque as a largely a specific bacterial colonization issue. This study raises questions about the early pathogenicity of plaque accumulation in periodontitis. More studies are warranted.
