Background To evaluate the temperature values including initial, maximum, and rising caused by light-cured materials used for direct capping during polymerisation. Methods A 3 mm deep, wide, and length class-I cavity was prepared to a premolar tooth, leaving hard tissue at the pulpal floor of 1 mm thickness with a 1 mm diameter of exposure. The sample was placed in a customised mimicry setup in which the temperature was standardised (37 degrees C) by a double-verified system. Light-curing capping materials (Theracal LC, Theracal PT, Harvard BioCal, and Ultrablend Plus) were placed, polymerised, and temperature values were recorded. Kruskal-Wallis test was used to compare parameters among groups, and Dunn's test was used to define the group that caused the difference (p < 0.05). Results There were statistically significant differences between the materials in terms of initial, maximum, and temperature rising values (p(in)=0.014, p(max)=0.034, p(tr)= 0.016). The values of Theracal PT were measured highest in terms of temperature increase, while no statistically significant difference was observed between other materials during polymerisation. Conclusions Theracal PT caused higher temperature rise, however, it did not exceed 5.6 degrees C, which is the critical value for the pulp. Theracal PT should be used with caution as its use during direct capping causes high temperature increases, and there is a need for a light-curing regime to be designed for its use.
