Linear thermal coefficients of expansion () of seven commercial composite resins and four pit and fissure sealants were determined between 0 and 60°C on a thermomechanical analyzer. The thermal expansion curves obtained were nonlinear. Values of ranged from 26.5 to 39.6 x 10^-6 °/C for the composite and from 70.9 to 93.7 x 10^-6/°C for the sealants.
