background: pain control during and after surgeries can reduce subsequent complications, improve the recovery period of the patient after the surgery and immediately after discharge from the hospital, and shorten the length of stay in the hospital. objectives: the present research aimed to study the relationship between the depth of anesthesia and severity of pain after general anesthesia. meth...

Abstract Objective The effect of polymerization time and resin shade on the depth cure (DOC) two nano-hybrid composites (Filtek Z250 XT IPS Empress Direct) was evaluated compared. Materials Methods Sixty specimens were prepared from shades (A1 A3) composites. allocated into groups that further divided three subgroups depending (20, 40, 60 sec; n = 5). After that, DOC by calculating polymerized ...

PURPOSE To evaluate the depth of cure and surface hardness of two resin composites when subjected to three preheating temperatures, three polymerization times and two types of curing lights. METHODS Two resin composites were used in this study (Esthet-X and TPH), three polymerization times (10, 20, 40 seconds), three preheating temperatures (70, 100, 140 degrees F/21.1, 37.7 and 60 degrees C)...
