TI  - The effect of different light-curing methods on temperature changes of dual 
      polymerizing agents cemented to human dentin.
PG  - 57-64
AB  - AIM: This in vitro study aims to measure the temperature changes of resin luting 
      cements cemented to human dentin when using different light curing systems for 
      photo-activation. METHODS AND MATERIALS: The three different types of 
      light-curing units (LCUs) used for photoactivation were quartz-tungsten halogen 
      (QTH), light emitting diode (LED), and plasma arc (PAC). Two types of dual cure 
      resin cements were used [Variolink II (VL) and Choice (CH)]. Feltik Z250 
      composite resin material was used to prepare composite discs. Thirty human dentin 
      specimens were prepared for each resin luting cement (ten for each light source). 
      A total of 60 specimens were fabricated. Resin cement was applied on a dentin 
      bridge and covered with the prepared composite disc where specimens were 
      fabricated. Temperature change was recorded with a digital thermometer. RESULTS: 
      The lowest temperature was recorded when VL and CH were photo-activated with the 
      PAC unit. The PAC unit produced significantly lower recorded temperatures than 
      the LED and QTH units. No significant difference appeared between QTH and LED 
      units in terms of recorded temperature. CONCLUSION: The PAC unit produced 
      significantly lower temperature changes compared to QTH and LED curing units. The 
      risk for temperature rise should be taken into consideration during 
      photo-polymerization of adhesive resins with LED or QTH in deep cavities when 
      dentin thickness is 0.5 mm.
