    Objective: To determine the total oxidant status (TOS), total antioxidant status (TAS), and the 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels and their interrelationship in the saliva of children undergoing fixed orthodontic therapy. Materials and Methods: Thirty children were randomly divided into three groups. The attachments were bonded to all of the teeth using three different orthodontic composites: Transbond XT, Kurasper F, and GrenGloo. The salivary levels of TOS, TAS, and 8-OHdG were determined three times, as follows: before treatment (T-1) and at 1 month (T-2) and 3 months (T-3) following appliance placement. All data were statistically analyzed. Results: There were no significant differences in TOS, TAS, and 8-OHdG within the same time periods among the three different orthodontic composites (P > .05). TAS in all composite groups decreased over time. These decreases were found to be significant for Kurasper F and GrenGloo at the T1 T3 and T2 T3 time periods (P < .05). In all composite groups 8-OHdG decreased between T1 and T2 (P < .05). However, 8-OHdG in all composite groups increased from T2 to T3. These differences in 8-OHdG were significant in Kurasper F and GrenGloo (P < .05). Conclusions: Fixed orthodontic appliances bonded with the tested composites did not increase the cytotoxicity markers in saliva.

    Turkish Validity and Reliability Study of the Scale of Psychosocial Assessment of Candidates for Transplantation (PACT)
    (Elsevier Science Inc, 2023) Gunes, Dilek; Erci, Behice; Uncu, Fatos; Saritas, Serdar
    Background. The Psychosocial Assessment of Candidates for Transplantation (PACT) scale shows a statistically acceptable level of reliability and validity and can guide clinicians in managing transplant candidates. This study aims to adapt PACT scale to Turkish and evaluate its validity and reliability for Turkish transplant candidates.Methods. This was a psychometric study of a sample of 162 patients in the organ transplant services of 2 hospitals in Turkey. The number of patients enrolled in the study was 20 times the number of items on the scale. The research data were collected using PACT. Descriptive statistics, Cronbach's alpha reliability coefficient, Pearson correlation, and factor analysis were used to evaluate the data.Results. The data were analyzed using varimax rotation in principal component analysis. The factor loadings of the items ranged from 0.56 to 0.79. The internal reliability coefficient of the scale is 0.87. It was also found that the scale accounted for the 52.82% of the total variance.Conclusion. According to the results of this study, evidence of the validity and reliability of the PACT was obtained.
