PURPOSE. To assess removable prosthetic restoration tolerance according to the patient section of the short form of the Gagging Problem Assessment Questionnaire (GPA-pa SF) and the influence of gender, education level and prosthesis type and denture-related mucosal irritation on the GPA-pa SF scores before treatment and over a period of two months after prosthesis insertion. MATERIALS AND METHODS. 130 participants who required removable prosthesis were surveyed with a standard form that included questions regarding age, gender, education level, dental attendance, and prosthetic restoration type. Participants answered the GPA-pa SF before restoration (T0) and 1 day (T1), 2 days (T2), 15 days (T3), 1 month (T4), and 2 months (T5) after prosthesis insertion. RESULTS. Of the 130 participants, 110 participants completed the prosthetic restoration procedure, but only 93 of these were able to use the prosthesis over the two-month period. The mean GPA-pa SF score obtained at T0 was higher than the scores obtained at the other periods in the total of the sample. Significant difference was present between mean scores obtained at T0-T1 and T2-T3 than scores obtained at other periods (P<.05). Female participants and participants with denture-related mucosal irritation had higher GPA-pa SF scores at all time points analysed. Significant difference was present between mean GPA-pa SF scores obtained at T2-T3 than scores obtained at other periods for females and participants with denture-related mucosal irritation (P<.05). Education level and prosthesis type did not significantly influence the GPA-pa SF score at any time point analysed (P>.05). CONCLUSION. GPA-pa SF scores were higher before the restoration procedure began, and decreased over time with the use of prosthesis. Gender and denture-related mucosal irritation affected the GPA-pa SF scores.

Biofilm-forming ability and adherence to poly-(methyl-methacrylate) acrylic resin materials of oral Candida albicans strains isolated from HIV positive subjects

PURPOSE. This study evaluated the adhesion to acrylic resin specimens and biofilm formation capability of Candida albicans strains isolated from HIV positive subjects' oral rinse solutions. MATERIALS AND METHODS. The material tested was a heat-cured acrylic resin (Acron Duo). Using the adhesion and crystal violet assays, 14 oral Candida albicans isolated from HIV-positive subjects and 2 references Candida strains (C. albicans ATCC 90028 and C. albicans ATCC 90128) were compared for their biofilm production and adhesion properties to acrylic surfaces in vitro. RESULTS. There were no significant differences in adhesion (P=.52) and biofilm formation assays (P=.42) by statistical analysis with Mann-Whitney test. CONCLUSION. Denture stomatitis and increased prevalence of candidal carriage in HIV infected patients is unlikely to be related to the biofilm formation and adhesion abilities of C. albicans to acrylic resin materials.

Awareness and Practices Regarding Breast and Cervical Cancer among Turkish Women in Gazientep

Karadag, Gulendam,Gungormus, Zeynep,Surucu, Ramazan,Savas, Esen,Bicer, Fulya Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.3

Background: Cancer is a major public health problem both in our country and worldwide due to its disease burden, fatality and tendency for increased incidence. In Turkey, breast cancer ranks first with an incidence of 41.6% and cervical cancer is the tenth most common cancer with an incidence of 4.4%. Objectives and Design: This descriptive, cross-sectional study was conducted with 240 women aged from 15 to 65 years admitted to a gynecology-obstetrics outpatient clinic of a private hospital in Gaziantep. Study data were collected by the investigators through a 36-item questionnaire form which was generated using information gathered from similar surveys in the literature. Results: It was determined that 34.6% of women were high-school graduates, and 64.2% had a medium income level. The majority (79.2%) stated that they never performed BSE and 49.5% of them said that they did not know how to do it. Some 79.2% did not know what a Pap smear was and 73.3% had not experienced a smear test ever. Conclusions: In this study, we found that most of the women had insufficient knowledge of breast and cervical cancer, while knowledge and practices increased with the education level. Based on these findings, we suggest that there is a need for planning, implementation and assessment of health policies and healthcare services at the national and regional level and we believe that nurses working in the field of protective health services should develop educational programmes for women with a primary focus on cancer in order to increase awareness among the female population in Turkey.

Cultural Affordance, Motivation, and Affective Mathematics Engagement in Korea and the US

Investigating the relationship between intrinsic and extrinsic motivation and their effects on affective mathematics engagement in a cultural context is critical for determining which types of motivation promote affective mathematics engagement and the relationship with cultural affordance. The investigation in the current study is comprised of two dependent studies. The results from Phase 1 indicate that attitude and emotion are better explained by extrinsic motivation, while self-acknowledgment and value are better explained by intrinsic motivation. The results of Phase 2 indicate that the Korean sample has greater extrinsic motivation, attitude, and emotion, while the U.S. sample has greater intrinsic motivation, self-acknowledgment, and value. The key outcome for this research is that disentangling cultural affordance from the emotional and cognitive structures is impossible.
