Objective: To investigate the persistence of staining after the use of chlorhexidine gluconate mouthrinse.
Method And Materials: Twenty-four subjects (nine women and 15 men) who underwent periodontal therapy and were prescribed the use of 0.2% chlorhexidine gluconate mouthrinse participated in this study.
Aim: The aim of this study was to evaluate the heat generation of three different types of light curing units.
Methods And Materials: Temperature increases were recorded from a distance of 1 mm from a thermocouple to the tip of three different types of light curing units including one quartz-tungsten halogen (QTH), one plasma arc (PAC), and one light emitting diode (LED) unit. An experimental model was designed to fix the 1 mm distance between the tip of the light curing units and the thermocouple wire.
