Purpose: The study examined the psychometric properties of the Korean Geriatric Depression Scale Informant-15 (KGDSI-15), an instrument measuring geriatric depression through their primary caregivers. Methods: The participants were 370 Korean older adults $\geqq$65-years-of-age registered in a visiting health center in S city. The Korean version of Geriatric Depression Scale-Short Form (GDSSF-K) was used for comparison. Internal consistency measured tool reliability and Pearson correlation coefficient measured validity. One-way ANOVA was used to determine the clinical usability of the instrument: depression levels were classified as normal, mild depression, and severe using GDSSF-K, and the depression scores of these three groups were comparatively measured by KGDSI-15. Results: The Cronbach's alpha coefficient was .831. The correlation coefficient with GDSSF-K was r=.616 (p<.001). KGDSI-15 results showed the depression level of older adults with severe depression was highest followed by those with mild depression and normal. The group differences were also statistically significant, which indicated the clinical usability of the instrument. Conclusion: KGDSI-15 is suggested to be reliable and valid to measure the geriatric depression through the primary caregivers of older adult.

Restoring composite resins with the optimal shades for all primary teeth is a great challenge for pediatric dentists. A newly developed single-shade composite resin can exhibit a color similar to that of the surrounding tooth structure based on the structural color phenomenon. This study aims to evaluate the color adjustment potential (CAP) of a single-shade composite resin compared to conventional multi-shade composite resins in primary teeth. A single-shade composite resin and two conventional multi-shade composite resins were included in this study. Two types of specimens, a single specimen and a dual specimen, were evaluated. For single specimens, duplications of the primary second molar denture teeth were made using experimental composite resins. For dual specimens, cavities were prepared on the buccal surfaces of extracted primary second molars and restored with experimental composite resins. The L<sup>*</sup>, a<sup>*</sup>, and b<sup>*</sup> values were measured using a colorimeter for the extracted teeth and specimens. The mean ΔE<sub>ab</sub><sup>*</sup> values for single and dual specimens and CAP were calculated. Bonferroni post-hoc analysis was performed to confirm the statistical significance between the ΔE<sub>ab</sub><sup>*</sup> and CAP values of the experimental resins. Among the single specimens, the single-shade composite resin showed significantly higher ΔE<sub>Single</sub> compared to other composite resins (p < 0.0167). There was no significant difference between ΔE<sub>Dual</sub> for all experimental resins. The single-shade composite resin showed highest CAP compared to other multi-shade composite resins. A single-shade composite resin exhibited the most prominent color adaptability compared to other conventional multi-shade composite resins for primary second molars. A single-shade composite resin can simplify shade matching and provide esthetic outcomes for the restoration of primary second molars.
