PURPOSE: The purpose of this study was to investigate the effect of various surface treatments (ST) on the shear bond strength of resin composite to three bilayer dental ceramics made by CAD/CAM and two veneering ceramics. MATERIALS AND METHODS: Three different bilayer dental ceramics and two different veneering ceramics were used (Group A: IPS e.max CAD+IPS e.max Ceram; Group B: IPS e.max ZirCAD+IPS e.max Ceram, Group C: Vita Suprinity+Vita VM11; Group D: IPS e.max Ceram; Group E: Vita VM11). All groups were divided into eight subgroups according to the ST. Then, all test specimens were repaired with a nano hybrid resin composite. Half of the test specimens were subjected to thermocycling procedure and the other half was stored in distilled water at 37℃. Shear bond strength tests for all test specimens were carried out with a universal testing machine. RESULTS: There were statistically significant differences among the tested surface treatments within the all tested fracture types (P < .005). HF etching showed higher bond strength values in Groups A, C, D, and E than the other tested ST. However, bonding durability of all the surface-treated groups were similar after thermocycling (P>.00125). CONCLUSION: This study revealed that HF etching for glass ceramics and sandblasting for zirconia ceramics were adequate for repair of all ceramic restorations. The effect of ceramic type exposed on the fracture area was not significant on the repair bond strength of resin composites to different ceramic types.

PURPOSE: The purpose of this study was to examine the psychometric properties of the Children's Somatization Inventory (CSI) in Turkish schoolchildren and adolescents. METHODS: The CSI was translated using translation and back-translation. The participants were 813 schoolchildren, adolescents and their parents (n = 453). Content and construct validity were assessed to test the validity of the CSI-24. Internal consistency reliability, interrater reliability (child-parent agreement) and test-retest reliability were assessed to test the reliability of the CSI-24. RESULTS: Psychometric analyses of the Turkish version of the CSI-24 indicate high reliability and good content and construct validity. CONCLUSION: The Turkish version of the CSI-24 is a useful instrument for measuring self-reported somatic complaints in Turkish schoolchildren and adolescents between the ages of 9 and 15.

PURPOSE: The aim of this research was to adapt the Sun Protection Behavior Scale (SPBS) to Turkish and to perform validity and reliability analyses. METHODS: The scale was administered to a total of 900 adolescents, the retest to 91 adolescents. The construct validity of the scale was evaluated using exploratory (EFA) and confirmatory factor analysis (CFA). The EFA and CFA were applied to sample groups of 449 and 451 people, respectively. RESULTS: The Cronbach alpha coefficients for the Turkish form of the SPBS (alpha = .74) and its sunscreen (alpha = .88) and hat use (alpha = .70) subscales were found to be > or =.70 while the sun avoidance subscale was calculated to be .67. The item-total score correlation between the scale and its subscales was > or =.26 and the test-retest correlations were found to be > or =.51. The CFA results verified the 8-item, 3-factor Turkish version of the SPBS. The confirmatory factor loadings for the scale were .45-.80 for sun avoidance, .72-.93 for sunscreen use, and .66-.83 for hat use. In particular, SPBS and sunscreen use (p < .001) exhibited significantly high mean scores among girls and economically better backgrounds (p = .007, p < .001, respectively). In addition, SPBS (p = .004) and hat use (p < .001) revealed that the mean scores were significantly high in younger adolescents. CONCLUSIONS: The SPBS was found to be valid and reliable and its psychometric characteristics acceptable. The scale can be used to measure the behavior of Turkish adolescent populations with respect to sun protection.

Background: Internalized stigma, adoption of negative attitudes and stereotypes of the society regarding persons’ illness, has not been studied previously in pediatric psoriasis patients. Objective: We aimed to investigate the internalized stigma in pediatric psoriasis patients and to determine differences according to factors affecting internalized stigma compared to adult psoriasis patients. Methods: This multicenter,cross-sectional, comparative study included 125 pediatric (55 female, 70 male; mean age±standard deviation [SD], 14.59±2.87 years) and 1,235 adult psoriasis patients (577 female, 658 male; mean age±SD, 43.3±13.7 years). Psoriasis Internalized Stigma Scale (PISS), Dermatology Life Quality Index (DLQI), Perceived Health Status (PHS), and the General Health Questionnaire (GHQ)-12 were the scales used in the study. Results: The mean PISS was 58.48±14.9 in pediatric group. When PISS subscales of groups were compared, the pediatric group had significantly higher stigma resistance (p=0.01) whereas adult group had higher scores of alienation (p=0.01) and stereotype endorsement (p=0.04). There was a strong correlation between mean values of PISS and DLQI (r=0.423, p=0.001). High internalized stigma scores had no relation to either the severity or localization of disease in pediatric group. However, poor PHS (p=0.007) and low-income levels (p=0.03) in both groups, and body mass index (r=0.181, p=0.04) in the pediatric group were related to high PISS scores. Conclusion Internalized stigma in pediatric patients is as high as adults and is related to poor quality of life, general health, and psychological illnesses. Unlike adults, internalized stigma was mainly determined by psoriasis per se, rather than disease severity or involvement of visible body parts, genitalia or folds.
