This study examines the relationship between recuperation nurses' oral health knowledge and perceptions and senile denture management behavior. For this study, 198 recuperation nurses who work in recuperation facilities for elderly patients in Andong City, Gyeongsangbuk-do, are surveyed. The data are investigated statistically using t-test, ANOVA, Pearson's correlation analyses, and logistics regression analyses. The analyses results demonstrate that the rate of correct answers for oral health knowledge of recuperation nurses is 76.5%. The relationship between oral health perceptions and oral health knowledge is 0.324, which is slightly high correlation(p<0.01). In addition, the potential of senile denture management behavior is more likely among nurses who have high levels of oral health knowledge and perceptions. Therefore, it is necessary to explore measures that can promote denture management and oral health for the elderly who enter recuperation facilities through helping raise the level of recuperation nurses' oral health knowledge and perceptions.

Ni-Ti alloy has excellent corrosion resistance, biocompatibility, shape memory effect and superelasticity, so it has been used widely in biomedical fields. But it has difficulty in casting due to its high melting temperature and oxygen affinity at high temperature. Recently it has been attempted to cast Ni-Ti alloy using new casting machine and investment. The purpose of this study was to examine the superelastic behavior of cast shape memory Ni-Ti alloy and to compare the mechanical properties of the cast shape memory alloy with those of commercial alloys for removable partial denture framework. Ni-Ti alloy(Ni 50.25%, Ti 49.75% : atomic ratio) was cast with dental argon-arc pressure casting machine and Type IV gold alloy, Co-Cr alloy, Ni-Cr alloy, pure titanium were cast as reference. Experimental cast Ni-Ti alloy was treated with heat($500{\pm}2^{\circ}C$) in muffle furnace for 1 hour. Transformation temperature range of cast Ni-Ti alloy was measured with differential scanning calorimetry. The superelastic behavior and mechanical properties of cat Ni-Ti alloy were observed and evaluated by three point bending test, ultimate tensile test, Vickers microhardness test and scanning electron microscope. The results were as follows : 1. Cast Ni-Ti alloy(Ni 50.25%, Ti 49.75% : atomic ratio) was found to have superelastic behavior. 2. Stiffness of cast Ni-Ti alloy was considerably lesser than that of commercial alloys for removable partial denture. 3. Permanent deformation was observed in commercial alloys for removable partial denture framework at three point bending test over proportional limit(1.5mm deflection), but was not nearly observed in cast Ni-Ti alloy. 4. On the mechanical properties of ultimate tensile strength, elongation and Vickers microhardness number, cast Ni-Ti alloy was similiar to Type IV gold alloy, Co-Cr alloy, Ni-Cr alloy and pure titanium. With these results, cast Ni-Ti alloy had superelastic behavior and low stiffness. Therefore, it is suggested that cast Ni-Ti alloy may be applicated to base metal alloy for removable partial denture framework.

Objectives: The purpose of this study was to investigate the influencing factors of removable dentures satisfaction in the elderly. Methods: A self-reported questionnaire was filled out by 256 elderly in Jeollanam-do from September 1, 2013 to June 30, 2014. The questionnaire consisted of general characteristics of the subjects, denture related characteristics systemic health characteristics and dental health behavior. Removable dentures satisfaction was adapted from Ban. The questionnaire for Removable dentures satisfaction included general treatment satisfaction, masticatory function satisfaction, denture retention satisfaction, aesthetic satisfaction measured by Likert 5 scale. Cronbach's alpha was 0.850 in the study. Data were analyzed for a t-test, one-way ANOVA and multiple regression analysis by using SPSS(SPSS 18.0, USA) program. Results: According to subjective and systemic health condition and oral health condition, there was a statistically significant increase in general satisfaction of treatment, masticatory satisfaction of function, denture satisfaction of retention, aesthetic satisfaction. The overall satisfaction for removable denture showed a significant improvement. In the multiple regression analysis, variation of removable denture satisfaction was positively associated with oral health status{good(b=0.736, p=0.000)}, denture treatment services{dental hospital clinic(b=0.327, p=0.023)}, and systemic health status{good(b=0.241, p=0.047)}. Conclusions: Satisfaction of removable dentures may have a positive impact on oral health condition, hospital type, and associated systemic disease. It is necessary to develop incremental care programs for oral health and systemic health and to make public opinion to encourage the program.

The defects of partial denture frameworks are mainly shrinkage porosity, inclusions, micro-crack, particles from investment, and dendritic structure. In order to investigate a good casting condition of partial denture frameworks, the three casting alloys and casting methods were used and detected casting defects were analyzed by using electrochemical methods. Three casting alloys (63Co-27Cr-5.5Mo, 63Ni-16Cr, 63Co-30Cr-5Mo) were prepared for fabricating partial denture frameworks with various casting methods; centrifugal casting (Kerr, USA), high frequency induction casting (Jelenko Eagle, USA), vacuum pressure casting (Bego, Germany). The casting temperature was $1,380^{\circ}C$ (63Co-27Cr-5.5Mo and 63Ni-16Cr) and $1,420^{\circ}C$ (63Co-30Cr-5Mo). The casting morphologies were analyzed using FE-SEM and EDX. The corrosion test of the dendritic structure was performed through potentiodynamic method in 0.9% NaCl solutions at $36.5^{\circ}C$ and corrosion surface was observed using SEM. The defects of partial denture frameworks improved in the order of centrifugal casting, high frequency induction casting, and vacuum pressure casting method, especially, pore defects were found at part of clasp in the case of centrifugal casting method. The structure of casting showed dendritic structure for three casting alloys. In the 63Co-27Cr-5.5Mo and 63Co-30Cr-5Mo, $\alpha$-Co and $\varepsilon$-Co phases were identified at matrix and $${\gamma}$-Ni_2$Cr second phase were shown in 63Ni-16Cr. Also, the corrosion resistance of cast structure increased in the order of vacuum pressure casting, high frequency induction casting, and centrifugal casting method.
