Background: The etiologies of childhood dental fear/dental behavior management problems have been extensively studied, especially the role of children's temperaments. This study aimed to evaluate the effect of temperament and its associated variables on the anxiety and cooperation level of preschool children in a dental clinic.
Materials And Methods: This cross-sectional study involved 103, 4-6-year-old patients (39 boys and 64 girls).

Methods: A total of 30 patients with previous composite restorations and 30 patients with porcelain restorations on lateral and central incisors were selected. To simulate the effect of dental torque change, we asked the patients to tilt their heads upwards and downwards to represent buccal and palatal crown torque, respectively.
Background: There is a close relationship between the effects of free radicals and apoptosis, and vitamin C is known as a potent scavenger of free radicals.
Objective: The aim of this study was to evaluate the effect of vitamin C against the radiation-induced apoptosis and the ratio of Bax/Bcl-2 proteins in peripheral blood lymphocytes in patients undergoing cardiac procedures in vivo condition.
Material And Methods: In this clinical intervention study, blood samples from 6 patients in the first group were taken to assess the effect of radiation on the apoptosis and Bax/Bcl-2 proteins ratio, and 5 patients as the second group to evaluate the effect of vitamin C on the apoptosis and Bax/Bcl-2 proteins ratio before and 24 hours after the examination.
