Action-Packed Action Research: How Comic Books, Questions, and Reflection Can Transform Information Literacy Instruction

How many questions can you generate when looking at a single comic panel? Which are researchable, and why? These are questions that we’ve asked our students and our library colleagues. We invite you to ask these questions and more, and consider the broader significance of question-asking and reflective teaching to information literacy and ask if there is a place for comics -- or image-laden materials -- in your classroom

10 Research Experiences: An Active and Applicable Alternative to the Laundry List

A common requirement for students writing research papers in college is a “laundry list” of sources (e.g., an academic journal article; a “popular” article from a magazine or newspaper; a book or book chapter; and a website) they must locate and use in the final paper. In our experience as reference and instruction librarians, students are prone to checking items off these types of lists without really understanding why they are doing so. Absent context, the list simply becomes mechanical and students put forth the minimum effort required to cross items off. We realized that the goal with these “laundry lists” is to encourage students to see new ways of doing research (i.e., besides using natural language searching in Google) and to begin to evaluate which of these options is best in a given situation. In order to make this a more authentic learning experience for them, we thought that it would be better to focus on the experiences (e.g., where/ how they search) rather than the items they needed to locate

Shifting the Balance of Power: Asking Questions about the Comics-Questions Curriculum

We shift the balance of power in this paper by discussing a particular library lesson, the Comics-Questions Curriculum, with some of the students who participated in it, several years after they completed the workshop. By interviewing students and including them as co-authors of this paper, we re-center students in our analysis of this curriculum. In the process of reflecting on our work with the students and each other, we begin to see ways to engage in more meaningful, longer-term assessment of our classroom work while involving student voices in the process. We share our experiences here in order to take an honest look at our sometimes messy, unclear process, in the hope that others may reflect on, critique, and build on our work

Clinical and radiographic outcomes of zirconia dental implants-A systematic review and meta-analysis.

peer reviewed[en] OBJECTIVES: For the present review, the following focused question was addressed: In patients with root-analog dental implants, what is the effect of implants made of other materials than titanium (alloy) on implant survival, marginal bone loss (MBL), and technical and biological complications after at least 5 years. MATERIALS AND METHODS: An electronic (Medline, Embase, Web of Science) search was performed to identify observational clinical studies published from January 2000 investigating a minimum of 20 commercially available zirconia implants with a mean follow-up of at least 60 months. Primary outcome was implant survival, secondary outcomes included peri-implant MBL, probing depths (PDs), and technical and biological complications. Meta-analyses were performed to evaluate implant survival, MBL, and PD. RESULTS: From 5129 titles, 580 abstracts were selected, and 111 full-text articles were screened. Finally, 4 prospective and 2 retrospective observational clinical cohort studies were included for data extraction. Meta-analyses estimated after 5 years of loading mean values of 97.2% (95% CI 94.7-99.1) for survival (277 implants, 221 patients), 1.1 mm (95% CI: 0.9-1.3) for MBL (229 implants, 173 patients), and 3.0 mm (95% CI 2.5-3.4) for PDs (231 implants, 175 patients). CONCLUSIONS: After 5 years, commercially available zirconia implants showed reliable clinical performance based on survival rates, MBL, and PD values. However, more well-designed prospective clinical studies and randomized clinical trials investigating titanium and zirconia implants are needed to confirm the presently evaluated promising outcomes

Clinical outcomes and cost effectiveness of computerâ guided versus conventional implantâ retained hybrid prostheses: A longâ term retrospective analysis of treatment protocols

BackgroundComputerâ guided systems were developed to facilitate implant placement at optimal positions in relation to the future prosthesis. However, the time, cost and, technique sensitivity involved with computerâ guided surgery impedes its routine practice. The aim of this study is to evaluate survival rates and complications associated with computerâ guided versus conventional implant placement in implantâ retained hybrid prostheses. Furthermore, longâ term economic efficiency of this approach was assessed.MethodsPatients were stratified according to implant placement protocol into a test group, using computerâ guided placement, and a control group, using traditional placement. Calibrated radiographs were used to measure bone loss around implants. Furthermore, the costs of the initial treatment and prosthetic complications, if any, were standardized and analyzed.ResultsFortyâ five patients (149 implants in the test group and 111 implants in the control group) with a minimum followâ up of 5 years, and a mean followâ up of 9.6 years, were included in the study. While no significant difference was found between both groups in terms of biologic and technical complications, lower incidence of implant loss was observed in the test group (P  0.05).ConclusionsComputerâ guided implant placement for an implantâ supported hybrid prosthesis is a valid, reliable alternative to the traditional approach for implant placement and immediate loading. Computerâ guided implant placement showed higher implant survival rates and comparable longâ term cost to nonâ guided implant placement.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/145504/1/jper10157.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/145504/2/jper10157_am.pd

The effect of different abutment materials on peri-implant tissues-A systematic review and meta-analysis.

peer reviewed[en] OBJECTIVES: In patients with dental implants, what is the effect of transmucosal components made of materials other than titanium (alloys) compared to titanium (alloys) on the surrounding peri-implant tissues after at least 1 year? MATERIALS AND METHODS: This systematic review included eligible randomized controlled trials identified through an electronic search (Medline, Embase and Web of Science) comparing alternative abutment materials versus titanium (alloy) abutments with a minimum follow-up of 1 year and including at least 10 patients/group. Primary outcomes were peri-implant marginal bone level (MBL) and probing depth (PD), these were evaluated based on meta-analyses. Abutment survival, biological and technical complications and aesthetic outcomes were the secondary outcomes. The risk of bias was assessed with the RoB2-tool. This review is registered in PROSPERO with the number (CRD42022376487). RESULTS: From 5129 titles, 580 abstracts were selected, and 111 full-text articles were screened. Finally, 12 articles could be included. Concerning the primary outcomes (MBL and PD), no differences could be seen between titanium abutment and zirconia or alumina abutments, not after 1 year (MBL: zirconia: MD = -0.24, 95% CI: -0.65 to 0.16, alumina: MD = -0.06, 95% CI: -0.29 to 0.17) (PD: zirconia: MD = -0.06, 95% CI: -0.41 to 0.30, alumina: MD = -0.29, 95% CI: -0.96 to 0.38), nor after 5 years. Additionally, no differences were found concerning the biological complications and aesthetic outcomes. The most important technical finding was abutment fracture in the ceramic group and chipping of the veneering material. CONCLUSIONS: Biologically, titanium and zirconia abutments seem to function equally up to 5 years after placement

Alternative therapies in controlling oral malodour: a systematic review.

peer reviewedIs there a role for alternative therapies in controlling intra-oral halitosis? Treatments other than tongue cleaning and anti-halitosis products containing zinc, chlorhexidine and cetylpyridinium chloride were considered as alternative therapies. Four databases were searched (PubMed, EMBASE, Web of Science and The Cochrane Library). Inclusion criteria were: examination of alternative halitosis therapies, study population with oral malodour, a (negative or positive) control group and evaluation of breath odour via organoleptic and/or instrumental assessment. Data were extracted for descriptive analysis. The screening of 7656 titles led to the inclusion of 26 articles. Analysis showed heterogeneity concerning the population of interest (from cysteine-induced to genuine halitosis), the examined treatment and the reported outcomes. This made a meta-analysis impossible. Essential oils, fluoride-containing products and herbal substances were the most studied. Results varied enormously and none of the active ingredients had an unambiguously positive effect on the malodour. The risk of bias was assessed as high in all articles. Given the fact that little evidence was found for each of the investigated treatments, it could be concluded that there is currently insufficient evidence that alternative therapies are of added value in the treatment of halitosis.Clinical relevanceScientific rationale:Halitosis is a common problem causing social isolation. Out of embarrassment, patients search the internet, leading to many questions about alternative solutions (e.g. oil pulling, herbs). This is the first systematic review on these alternative therapies.Principal findings: Results varied among studies. Some promising results were found for fluoride-containing toothpastes and probiotics. For other products (such as herbal and antibacterial products and essential oils) results were inconsistent. Long-term follow-up studies on these products are scarce. Moreover, the quality of the studies was poor.Practical implications:No clear evidence was found to support a certain alternative anti-halitosis therapy

Periodontal screening and referral behaviour of general dental practitioners in Flanders.

peer reviewedOBJECTIVES: The objective of this study was to investigate the screening and referral behaviour of Flemish dentists concerning periodontitis and more specific, the use of the Dutch Periodontal Screening Index (DPSI). MATERIALS AND METHODS: An online questionnaire was electronically distributed through the different professional dental societies. It consisted of two parts: the first aimed at describing the profile of the dentist. The second part inquired the screening method, when this was applied, periodontal risk factors and referral behaviour. RESULTS: One thousand fifty dentists attended to the questionnaire. One hundred fifty-nine questionnaires were excluded since they did not match the target audience. Sixty-four percent of Flemish dentists used DPSI as a periodontal screening method, 28% screened based on probing pocket depth, 4% used solely radiographs and 4% had no screening method at all. The usage of DPSI is influenced by the year of graduation: the longer the dentists were graduated, the less they used DPSI. No influence of sex, education centre and location was found. Referral behaviour is influenced by different patient- and dentist-related factors. CONCLUSIONS: Regarding the screening behaviour, there seems a consensus among Flemish dentists that a periodontal probe should be used. For referral, there is no consensus about if and when to refer to a specialist. CLINICAL RELEVANCE: It is encouraging that 92% of the Flemish general dental practitioners use a probe when screening for periodontitis. However, DPSI is mainly used by younger dentists. An effort should be made to encourage all dentists to use this, so that in every patient, periodontitis can be detected timely, securing the best treatment outcome
