Effect of Pulp Protection Technique on the Clinical Performance of Amalgam Restorations: Three-Year Results

This study evaluated the influence of the pulp protection technique on clinical performance of amalgam restorations after three years, with particular reference to post-operative sensitivity and secondary caries. One hundred and twenty (120) Class II amalgam restorations (68 premolars, 52 molars; 78 MOD, 42 OD/MO) were placed in 30 participants (four restorations per participant).The restorations were divided into four groups according to the pulp protection technique used: copal varnish; 2% neutral sodium fluoride; adhesive resin and no pulp protection. The parameters evaluated were post-operative sensitivity, staining of the dental structure, tooth vitality, partial or total loss of the restoration and secondary caries. One hundred and eight (108)restorations were available for evaluation after three years. No partial or total loss of restorations had occurred; all teeth were vital, no tooth structure staining or secondary caries was detected in any of the restored teeth. Post-operative sensitivity was observed only in two restorations at baseline and at seven-days. The three year clinical performance of teeth restored with a high copper dispersed phase amalgam was not affected by the choice of pulp protection technique

2006 Scholar\u27s Day Program

Scholars\u27 Day was established in 1997 and is a day-long conference devoted to showcasing the wide array of scholarship, research and creative activities occurring on campus. In 2012, a new emphasis on student research lead to a name change to Transformations: A Student Research and Creativity Conference. This event focuses on student research, which is defined as an original investigation or creative activity through the primary efforts of a student or group of students. The work should show problem-solving skills and demonstrate new conceptual outcomes.https://digitalcommons.cortland.edu/transformationsprograms/1016/thumbnail.jp

A Software Engineered Voice-Enabled Job Recruitment Portal System

The inability of job seekers to get timely job information regarding the status of the application submitted via conventional job portal system which is usually dependent on accessibility to the Internet has made so many job applicants to lose their placements. Worse still, the epileptic services offered by Internet Service Providers and the poor infrastructures in most developing countries have greatly hindered the expected benefits from Internet usage. These have led to cases of online vacancies notifications unattended to simply because a job seeker is neither aware nor has access to the Internet. With an increasing patronage of mobile phones, a self-service job vacancy notification with audio functionality or an automated job vacancy notification to all qualified job seekers through mobile phones will simply provide a solution to these challenges. In this paper, we present a Voice-enabled Job Recruitment Portal (JRP) System. The system is accessed through two interfaces – the voice user’s interface (VUI) and web interface. The VUI was developed using VoiceXML and the web interface using PHP, and both interfaces integrated with Apache and MySQL as the middleware and back-end component respectively. The JRP proposed in this paper takes the hassle of job hunting from job seekers, provides job status information in real-time to the job seeker and offers other benefits such as, cost, effectiveness, speed, accuracy, ease of documentation, convenience and better logistics to the employer in seeking the right candidate for a job

Analysis of the Effects of Formative Assessment in Promoting Transfer of Learning in an Undergraduate General Microbiology Laboratory Course

The undergraduate microbiology lab serves an important role in establishing a foundation of best practices in aseptic technique and infection control for pre-medical, pre-nursing, pre-pharmacy, or pre-allied health students. The high incidence of hospital-acquired infections (HAIs) in the US and evidence in the literature of less effective implementation of proper aseptic technique among apprentice doctors and nursing students suggests that more effective transfer of learning could improve implementation of these procedures in the clinical setting. The research described in this study aimed to assess learning transfer as it applied to aseptic techniques and infection control skills learned in the undergraduate microbiology lab from pre- and post-lab formative assessments to midterm and lab practical summative assessments. Assisting students in building connections between the aseptic techniques learned in general microbiology and their application in the clinical setting through pre-lab formative assessments and reflective practices may lead to improvements in use of aseptic techniques and infection control measures as they progress into clinical careers and may ultimately reduce infection rates and mortality rates due to HAIs. The first major aim of this study was to explore the experiences of students with respect to learning transfer through qualitative analysis of student responses to post-lab free-response questions regarding difficulties faced in the lab and the relevance of microbiology to students\u27 future careers. The second major aim of this study was to determine if the implementation of an in-class pre-lab formative assessment facilitates learning transfer as evidenced by significant improvements on summative lab midterm and final lab practical exam scores. Qualitative analysis of student responses to open-ended reflection questions indicated evidence of predominantly low-road transfer with respect to transfer of automaticity. Additionally, qualitative analysis of student responses indicated evidence of lateral transfer regarding transfer of complexity. Finally, there was evidence of an evolution from near to far transfer of context indicating that students were able to perceive the application of the knowledge gained in the microbiology lab in contexts similar to the lab as well as contexts outside of the lab. Evidence from student responses suggested that primarily students intending to pursue careers in healthcare fields were able to perceive specific applications of the microbiology lab to their future careers. Further, evidence from student responses suggested that students predominantly had difficulties with procedures, interpretation of results, manual dexterity with microbiological equipment and materials, and expressed the need to practice these procedures and techniques. Statistical analyses provided quantifiable evidence that the implementation of pre-lab quizzes had both a statistically significantly positive impact and a practically positive impact on lab practical final scores in both of the semesters studied as compared to historical control groups with a large effect size. The statistically and practically significant impact of the pre-lab quizzes on lab practical final exams is an important finding and will add to the current literature on the importance of formative assessment in undergraduate microbiology education

Changes to the Equine Hindgut Microflora in Response to Antibiotic Challenge

Antibiotics are important to equine medicine, but can cause detrimental side-effects including reduced feed intake, allergic reactions, and diarrhea. Antibiotic-associated diarrhea (AAD) is attributed to disruption of the hindgut microflora, permitting proliferation of pathogenic microbes. The objectives were to evaluate the effects of antibiotics on beneficial fecal bacteria, AAD-associated pathogens, microbial species richness and fermentation. Horses were assigned to treatment groups: control (no antibiotics, n=6), trimethoprim-sulfadiazine (oral, n=6), or sodium ceftiofur (IM, n=6). Fecal samples were taken during adaptation (3 wk), antibiotic challenge (1 wk), and withdrawal (1 wk). Fecal cellulolytics decreased by \u3e99% during challenge and did not recover during withdrawal (P \u3c 0.0001). Lactobacilli decreased by \u3e60% during challenge (P = 0.0453). Salmonella spp. increased 94% with trimethoprim-sulfadiazine challenge (P = 0.0115). There was no detectable Clostridium difficile during adaptation or in any control horse. C. difficile increased (P \u3c 0.0001) when horses were challenged, and remained elevated 7 d after withdrawal. There was no effect of challenge on in vitro digestibility or microbial species richness as evaluated by denaturing gradient gel electrophoresis (P \u3e 0.05). These results indicate that antibiotics can disrupt the normal flora and allow proliferation of pathogens, even without affecting digestibility and causing AAD
