<jats:p><jats:bold>Abstract</jats:bold> The approximate shear bond strength of subgingival calculus was measured on freshly extracted teeth. The experimental method was validated on polycarboxylate controls. The object was to specify a suitable upper limit for periodontal dressing adhesion, and a level of 4.0MN/m<jats:sup>2</jats:sup> is suggested by these results</jats:p>
