JARQUIN HERNANDEZ, Douglas  and  BONILLA, Silvia. Temperature increase on the tooth surface during photo-polymerization. Odontología Vital [online]. 2016, n.25, pp.17-22. ISSN 1659-0775.

It is known that the heat is realeased during light-curing of dental materials, either by the light emitting source or by the polymerization reaction of the compound used. This temperature increase is transmitted to tissues, which may have an effect on them. Due to this, a comparative study of the temperature reached during the sealing and reconstruction of teeth In vitro was performed, using light-curing lamps from the type quartztungsten- halogen (QTH), LED and lamps formed by 4 LEDs, analyzing their programming: Ramp Mode,

Intermittent Mode, and normal: and clinical guidelines are proposed in order to reduce potential thermal risks to the pulp and supporting tissues

Keywords : Light curing unit; LED; halogen; composite resin; thermal irritation.
