Analysis of Satisfaction with Removal Dental Prosthesis among Hansen`s Patients / 나학회지

The purposes of this study were to investigate the satisfaction of use of removable denture elated to general, functional and esthetic factors among dental patients in national sorokdo hospital, and to establish the structure relationships of dental treatment satisfaction. Two hundred fifty hansen`s patients who consented with this survey were selected and examined their oral status. Satisfaction degree was estimated by means of self-developed questionarires, filled out by face-to-face interview. Collected data were analyzed by t-tast The obtained results were as follow : 1. The satisfaction degree of four subscales was highest in esthetic actor (3.17+/-0.36), denture retention factor(3.10+/-0.60), general treatment satisfaction factor(2.94+/-0.56), and masticatory function factor (2.90+/-0.68) in descending order. It was appeared that patients was generally satisfied with all four factor. 2. On the comparison between proportion of denture satisfaction and satisfactio 02n of subscales, as the satisfaction of general treatment, masticatory function and denture retention were increased, the proportion of denture satisfaction of esthetic function and proportion of denture satisfaction. 3. The masticatiory function factor, denture retention factor and genernal satisfaction of treatment factor were directly affected on the denture satisfaction, but esthetic factor was affected indirectly on the denture satisfaction as a result of path analysis

Cellular characteristics of primary and immortal canine embryonic fibroblast cells

Using normal canine embryonic fibroblasts (CaEF) that were shown to be senescent at passages 7th-9th, we established two spontaneously immortalized CaEF cell lines (designated CGFR-Ca-1 and -2) from normal senescent CaEF cells, and an immortal CaEF cell line by exogenous introduction of a catalytic telomerase subunit (designated CGFR-Ca-3). Immortal CGFR- Ca-1, -2 and -3 cell lines grew faster than primary CaEF counterpart in the presence of either 0.1% or 10% FBS. Cell cycle analysis demonstrated that all three immortal CaEF cell lines contained a significantly high proportion of S-phase cells compared to primary CaEF cells. CGFR-Ca-1 and -3 cell lines showed a loss of p53 mRNA and protein expression leading to inactivation of p53 regulatory function, while the CGFR-Ca-2 cell line was found to have the inactive mutant p53. Unlike the CGFR-Ca-3 cell line that down-regulated p16INK4a mRNA due to its promoter methylation but had an intact p16INK4a regulatory function, CGFR-Ca-1 and -2 cell lines expressed p16INK4a mRNA but had a functionally inactive p16INK4a regulatory pathway as judged by the lack of obvious differences in cell growth and phenotype when reconstituted with wild-type p16INK4a. All CGFR-Ca-1, -2 and -3 cell lines were shown to be untransformed but immortal as determined by anchorage-dependent assay, while these cell lines were fully transformed when overexpressed oncogenic H-rasG12V. Taken together, similar to the nature of murine embryo fibroblasts, the present study suggests that normal primary CaEF cells have relatively short in vitro lifespans and should be spontaneously immortalized at high frequency.
