Determining the knowledge of women and their attitudes regarding gynecological cancer prevention.

The current study determines the knowledge of female course attendees of the "Municipality Cultural Center for Women", located in the city center of Sivas, Turkey, and their attitudes regarding gynecological cancer prevention. The participants of the study include 497 women attending one of the two Municipality Cultural Centers situated in the city center of Sivas. In this study, the sample was not selected; all participants were encompassed within the scope of our research. A total of 418 female course attendees who volunteered to participate in the research were identified as the sample. The data were collected during the months March-June 2011, by a questionnaire developed by the researchers. To compare the distribution of the collected data "Anova", "two independent t test examples" and "chi square test" were used. The research indicates that 45.1% of the women had had gynecological examination as a consequence of a physical disorder. The reason for 54.9% of the women to have gynecological examination is to have been scanned to check for gynecological cancer, 51.2% had a pap smear test. Some 34.9% of them had obtained information about cervical cancer, 39.7% via radio, television or internet and 36.3% from a doctor. Age, education level and marital status of the women participating in this study demonstrated statistically significant correlations (p<0.05) with gynecological examination and undergoing a pap smear test.

Effects of water storage of E-glass fiber reinforced denture base polymers on residual methyl methacrylate content.

This study investigated the effect of water storage on residual methyl methacrylate (MMA) content of continuous E-glass fiber (Wetrotex International) reinforced denture base polymers. Heat-polymerization (short- and long-term boiling and conventional curing cycle using Meliodent), autopolymerization (processed in air at room temperature and in water at 60 degrees C with the use of Meliodent Rapid Repair), and microwave-polymerization (3 min at 500 W with the use of Acron MC) were employed. The residual MMA contents of 120 specimens were analyzed by high-performance liquid chromatography at deflasking (control) and after water (37 degrees C) storage of 1 day, 1 week, and 1 month. Bonferroni's pairwise comparison test was used for statistical analysis. Significant reduction were determined only in the long-term terminal boiled heat-polymerized test group at the end of 1 day (p < 0.01), 1 week (p < 0.05) and also 1 month of water storage (p < 0.01). Significant reduction in autopolymerized test groups started even after 1 week of water storage (p < 0.05). Microwave-polymerized test groups did not show a significant residual MMA reduction in all time intervals (p > 0.05). The polymerization methods and cycles applied to the glass fiber reinforced denture base polymers influence both the content and the reduction of residual MMA after water storage.

Effect of glass fibre reinforcement on residual methyl methacrylate content of denture base polymers.

OBJECTIVES: Residual methyl methacrylate (MMA) content in unreinforced and in glass fibre reinforced, heat-polymerized (long- and short-term terminal boiled and conventionally) autopolymerized (at room temperature and in water at 60 degrees C) and microwave-polymerized (3min at 500W) denture base polymers after processing were compared. METHODS: Ten specimens were prepared for each curing cycle (five unreinforced and five reinforced) adding up to a total of 60. Residual MMA content was determined using high-performance liquid chromatography. Data were analysed with one-way ANOVA followed by Tukey HSD and Paired Samples tests. RESULTS: For unreinforced and reinforced groups; residual MMA content succesively ranked from lowest to highest in; long- and short-term terminal boiled heat-polymerized, microwave-polymerized, autopolymerized specimens processed in water at 60 degrees C and conventionally heat- and autopolymerized specimens processed at room temperature. Generally residual MMA was found more in glass fibre reinforced test groups than unreinforced groups. However, when reinforced residual MMA increased significantly in long- and short-term terminal boiled heat- (P<0.05) and microwave-polymerized test groups (P<0.01). CONCLUSIONS: Although this increase was significant, lowest residual MMA content was found succesively in reinforced long- and short-term terminal boiled heat-polymerized and microwave-polymerized like in unreinforced groups.
