"They're just, like, there": A constructivist grounded theory study of student experiences with school resource officers.

School-based policing has become common practice, but there is limited qualitative research examining what meanings students make of police presence in their schools. This study sought to understand how students construct narratives of police presence in their schools based on their experiences with school resource officers (SROs). Drawing on constructivist grounded theory methodology with a sample of 17 students, this study found that students are continuously integrating multiple conflicting narratives about SROs: students experience SROs as an established yet ambiguous presence, which produces mixed feelings of reassurance, wariness, and intimidation.

Mediotrusive Occlusal Contacts: Best Evidence Consensus Statement.

Purpose: The impact of mediotrusive (MT) occlusal contacts has been a topic of controversy and confusion in both clinical practice and in the dental literature. The purpose of this Best Evidence Consensus Statement was to explore whether MT interferences are harmful in the natural or therapeutic occlusion directed by 4 focus questions relating to prevalence, jaw function, jaw dysfunction and biomechanical models.

Materials And Methods: An electronic search in October 2020 sought evidence in MEDLINE (Ovid) using (mediotrus* OR nonworking side OR nonworking contact OR balancing side OR interfer* side OR premature contact) in the multipurpose (.

Intra- and inter-examiner agreement when assessing radiographic implant bone levels: Differences related to brightness, accuracy, participant demographics and implant characteristics.

Objectives: Evaluate intra- and inter-examiner agreement of radiographic marginal bone level (MBL) assessment around Brånemark single implants; and whether agreement related to radiograph brightness, discrimination level (accuracy), participant demographics or implant characteristics.

Materials And Methods: Seventy-four participants assessed MBLs of 100 digital radiographs twice with normal brightness, and twice with increased brightness. Intra-examiner agreement with and without increased brightness to the same thread, and within one thread; and inter-examiner agreement as compared with the group (defined by the mode) for the first assessments with and without increased brightness, to the same thread, and within one thread were calculated with Cohen's Kappa.

In vitro comparison of guided versus freehand implant placement: use of a new combined TRIOS surface scanning, Implant Studio, CBCT, and stereolithographic virtually planned and guided technique.

Implant placement requires precise planning and execution to avoid collision with critical anatomical structures. Technology advances may improve placement outcomes. The purpose of this study was to trial and measure in an in vitro environment the accuracy of placing a single dental implant in the planned position using a specific guided surgery technique compared with a freehand surgery technique.

Satisfaction and Patient-Related Outcomes in 128 Patients with Single Implant Crowns In Situ for up to 14 Years.

Purpose: To assess patient satisfaction and patient-related outcomes across the domains of appearance, cleansibility, and costs; the perceived value and worth when single implant crowns (SICs) had been in situ up to 14 years; whether satisfaction differed between patients; and whether certain characteristics might affect the questionnaire response rate.

Materials And Methods: Patients treated at a private prosthodontic practice between 2001 and 2014 (n = 207) who received a SIC (n = 256) were prospectively included. A previously validated patient satisfaction questionnaire (PSQ) exploring patient-centered outcomes was mailed to participants.

A Critical Review of Search Strategies Used in Recent Systematic Reviews Published in Selected Prosthodontic and Implant-Related Journals: Are Systematic Reviews Actually Systematic?

Purpose: The aim of this study was to outline how search strategies can be systematic, to examine how the searches in recent systematic reviews in prosthodontic and implant-related journals were structured, and to determine whether the search strategies used in those articles were systematic.

Materials And Methods: A total of 103 articles published as systematic reviews and indexed in Medline between January 2013 and May 2016 were identified from eight prosthodontic and implant journals and reviewed. The search strategies were considered systematic when they met the following criteria: (1) more than one electronic database was searched, (2) more than one searcher was clearly involved, (3) both text words and indexing terms were clearly included in the search strategy, (4) a hand search of selected journals or reference lists was undertaken, (5) gray research was specifically sought, and (6) the articles were published in English and at least one other language.

How to Find Dental Survival Articles: Using the New Search Strategies.

Clinicians and readers rely on accurate identification of articles to answer clinical questions and explore hypotheses. Commonly, these questions relate to the outcome and survival of dental treatments. Errors in indexing and inconsistencies in descriptions of these studies have meant that such articles are difficult to locate.

Research Waste: How Are Dental Survival Articles Indexed and Reported?

Purpose: Research waste occurs when research is ignored, cannot be found, cannot be used, or is unintentionally repeated. This article aims to investigate how dental survival analyses were indexed and reported, and to discuss whether errors in indexing and writing articles are affecting identification and use of survival articles, contributing to research waste.

Materials And Methods: Articles reporting survival of dental prostheses in humans (also known as time-to-event) were identified by searching 50 dental journals that had the highest Impact Factor in 2008.

Search Strategy to Identify Dental Survival Analysis Articles Indexed in MEDLINE.

Purpose: Articles reporting survival outcomes (time-to-event outcomes) in patients over time are challenging to identify in the literature. Research shows the words authors use to describe their dental survival analyses vary, and that allocation of medical subject headings by MEDLINE indexers is inconsistent. Together, this undermines accurate article identification.

Lost in translation: Review of identification bias, translation bias and research waste in dentistry.

Objective: To review how articles are retrieved from bibliographic databases, what article identification and translation problems have affected research, and how these problems can contribute to research waste and affect clinical practice.

Methods: This literature review sought and appraised articles regarding identification- and translation-bias in the medical and dental literature, which limit the ability of users to find research articles and to use these in practice.

Results: Articles can be retrieved from bibliographic databases by performing a word or index-term (for example, MeSH for MEDLINE) search.

Survey of the use of statistical methods in the international journal of prosthodontics.

Purpose: This survey aimed to review how scientific articles were reported and to describe the types of statistical tests that had been recently and commonly used in The International Journal of Prosthodontics.

Materials And Methods: All 174 articles published in 2012 and 2013 were hand-searched to identify scientific articles (n = 151) and those using at least one statistical test to explore results (n = 111). Editorials, letters, comments, erratum, and award proceedings were excluded.

Accuracy of medical subject heading indexing of dental survival analyses.

Purpose: To assess the Medical Subject Headings (MeSH) indexing of articles that employed time-to-event analyses to report outcomes of dental treatment in patients.

Materials And Methods: Articles published in 2008 in 50 dental journals with the highest impact factors were hand searched to identify articles reporting dental treatment outcomes over time in human subjects with time-to-event statistics (included, n = 95), without time-to-event statistics (active controls, n = 91), and all other articles (passive controls, n = 6,769). The search was systematic (kappa 0.

Will your article be found? Authors choose a confusing variety of words to describe dental survival analyses.

Objectives: Identify the words and phrases that authors used to describe time-to-event outcomes of dental treatments in patients.

Materials And Methods: A systematic handsearch of 50 dental journals with the highest Citation Index for 2008 identified articles reporting dental treatment with time-to-event statistics (included "case" articles, n = 95), without time-to-event statistics (active "control" articles, n = 91), and all other articles (passive "control" articles n = 6796). The included and active controls were read, identifying 43 English words across the title, aim and abstract, indicating that outcomes were studied over time.

Understanding Kaplan-Meier and survival statistics.

Purpose: This paper aims to explore the mathematics of Kaplan-Meier and survival statistics, explain how the mathematics are relevant for prosthodontic treatment planning, and provide advice for future presentation of such data.

Materials And Methods: The mathematics of the Kaplan-Meier and related survival statistic formulas were explored with hypothetical data consisting of 100 prostheses, reviewed yearly for 10 years. The hypothetical impact of failures (n = 1, 2, 9, or 0) and censored data (n = 5, 9, or 10) were reviewed across three life tables and survival curves.
