intrapulp temperature, photoirradiation's time, composite resin


  • Aim: The present study was performed to measure intrapulpal temperature when photoirradiation of composite resin and glass ionomer liner at different curing times.
  • Material and Methods:  Thermocouple (TC) was placed in the intrapulpal space of an extracted human mandibular premolar which had a ClassV cavity preparation (1.5mm dentin thickness remaining on the buccal surface), and restored with composite resin" a bulk fill "and with LED unit " a high-intensity " at different photoirradiation times (10, 20. & 40sec). A temperature increase was obtained during photo-irradiation.
  • Result: The Rise in intrapulpal temperature was associated with an increase in photo-irradiation times and significant in each study groups (p<0.05).
  •  Conclusion: intrapulpal temperature increase was attributed to photo-irradiation's time of composite resin. However, temperature's increase during polymerization were below the critical value.
