in Vitro Study of the Pulp Chamber Temperature Rise during Light-activated Bleaching
This study evaluated in vitro the pulp chamber temperature rise induced by the light-activated dental bleaching technique using different light sources. The root portions of 78 extracted sound human mandibular incisors were sectioned approximately 2 mm below the cementoenamel junction. The root cavities of the crowns were enlarged to facilitate the correct placing of the sensor into the pulp ch...
متن کاملIn vitro pulp chamber temperature rise during fabrication of provisional restorations on different types of teeth
Purpose: This in vitro study compared the temperature rise in the pulp chamber during fabrication of provisional resinous restorations on three types of teeth by a direct method. Materials and Methods: The tip of a thermocouple was positioned into the pulp chamber of thirty intact extracted human teeth. Then the teeth were divided into three different tooth groups (incisor, premolar, molar) and...
متن کاملPulp Chamber Temperature Rise during Resin Composite Polymerization
Objectives: To compare the pulp chamber temperature during illumination of resin-based composites using different light-curing units, and to assess the effects of a glass-ionomer (GI) base on the increase of pulp chamber temperature during polymerization. Material and Method: Standard occlusal cavities were prepared and restored with the adhesive bonding agent Clearfil Liner Bond 2V and the com...
متن کاملTemperature Rise Within the Pulp Chamber During Composite Resin Polymerisation Using Three Different Light Sources
UNLABELLED The purpose of the study was to compare temperature rise during polymerisation of resin based composites (RBCs) with two LED light curing units (LCUs) compared to a halogen control light. METHODS Forty-five extracted molars, patients aging 11-18 years were used. Thermocouples (TCs) were placed in contact with the roof of the pulp chamber using a 'split-tooth' method. Teeth were pla...
متن کاملA study of temperature rise in the pulp chamber during composite polymerization with different light-curing units.
AIM The study compared pulp temperature rise during polymerization of resin-based composites (RBCs) using halogen and LED light-curing units (LCUs). METHODS AND MATERIALS A total of 32 teeth extracted from patients aged 11-18 years were used in the study. Thermocouples placed on the roof of the pulp chamber using a novel 'split-tooth' method. In Group 1 a halogen LCU with a light intensity of...
