Effect of placement of calcium sulphate when used for the repair of furcation perforations on the seal produced by a resin-based material

Aim  To evaluate the sealing ability of calcium sulphate when used under composite resin for the repair of furcation perforations having different diameters. Methodology  Perforations of different diameter were created in the floors of pulp chambers in 60 extracted human molar teeth with either a nu...

Description
Summary:Aim  To evaluate the sealing ability of calcium sulphate when used under composite resin for the repair of furcation perforations having different diameters. Methodology  Perforations of different diameter were created in the floors of pulp chambers in 60 extracted human molar teeth with either a number 3 (1 mm diameter) or 5 (1.5 mm diameter) round bur. The specimens of each group were divided into four sub‐groups which were repaired with composite resin either alone or in combination with calcium sulphate that created an artificial floor (15 teeth group‐1). Eight teeth without furcation perforations served as negative controls. In the leakage detection device, 1 mol L−1 glucose solution was forced under a pressure of 1.5 KPa from the crown towards the pulp chamber floor. The concentration of leaked glucose was measured at 1, 2, 4, 7, 10, 15 and 20 days using a glucose oxidase method and the data evaluated using the rank sum test. Results  The specimens with larger perforations repaired with composite resin alone had significantly more leakage (P
