Interleukin-1 gene polymorphisms and chronic periodontitis in adult whites: a systematic review and meta-analysis.

Background: Interleukin-1 (IL-1) gene polymorphisms have been associated with increased levels of inflammatory mediators and several inflammatory diseases. Periodontitis is a bacterially induced chronic inflammatory disease that destroys the connective tissues and bone that support the teeth, affects substantial numbers of adults, and has been implicated as a contributing factor in systemic diseases. IL-1 gene polymorphisms, most prominently IL1A (-889), IL1A (+4845), and IL1B (+3954), have been associated with chronic periodontitis (CP) in whites.

Association between students' dental admission test scores and performance on comprehensive clinical exams.

This study examined the association between Dental Admission Test (DAT) scores and the comprehensive exams conducted at Harvard School of Dental Medicine. The authors hypothesized that students who scored high on the DAT would also perform well on the comprehensive examinations. Sixty-six students from the graduating classes of 2005 and 2006 were included.

The connection between selective referrals for radical cystectomy and radical prostatectomy and volume-outcome effects: an instrumental variables analysis.

Evaluation of a new assessment tool in problem-based learning tutorials in dental education.

The Harvard School of Dental Medicine (HSDM) uses a hybrid problem-based learning (PBL) approach to teaching in the D.M.D.

Association Between National Board Dental Examination Part II Scores and Comprehensive Examinations at Harvard School of Dental Medicine.

Harvard School of Dental Medicine (HSDM) uses a hybrid problem-based approach to teaching in the predoctoral program. The objective structured clinical examination (OSCE) is a formative examination designed to assess the performance of students in the problem-based learning (PBL) curriculum. At HSDM three comprehensive examinations with OSCE components are administered during the third and fourth years of clinical training.

Hospital emergency department visits attributed to pulpal and periapical disease in the United States in 2006.

Background: Relatively localized conditions such as infection of the pulp or periapical tissues if left untreated could spread and require hospital care. The objectives of this study were to assess the prevalence of such hospital-based emergency department (ED) visits, to quantify hospital charges associated with those visits, and to identify characteristics of those members of the population who are likely to make such visits.

Methods: The experimental design of this study involves the use of The Nationwide Emergency Department Sample for the year 2006.

Outcomes in patients visiting hospital emergency departments in the United States because of periodontal conditions.

Background: The chances of presenting to hospital emergency departments (EDs) are significantly higher in individuals who ignore regular dental care and in those with medical conditions. Little is known about nationwide estimates of hospital-based ED visits caused by periodontal conditions in the United States. The objective of this study is to determine the incidence of ED visits caused by periodontal conditions that occurred in a 2006 nationwide sample and to identify the risk factors for hospitalization during the ED visits.

Hospital based emergency department visits attributed to dental caries in the United States in 2006.

Objective: There is a paucity of published studies presenting nationally representative estimates on hospital-based emergency department visits primarily attributed to dental caries. The objective of this study is to provide estimates of hospital-based emergency department visits attributed to dental caries in the United States.

Complications rates of non-oncologic urologic procedures in population-based data: a comparison to published series.

Purpose: Published single institutional case series are often performed by one or more surgeons with considerable expertise in specific procedures. The reported incidence of complications in these series may not accurately reflect community-based practice. We sought to compare complication and mortality rates following urologic procedures derived from population-based data to those of published single-institutional case series.

Randomized trials published in the journal of dental research are cited more often compared with those in other top-tier non-specialty-specific dental journals.

Background And Aim: Randomized controlled trials (RCTs) are viewed as the gold standard for clinical research. Oftentimes the citation counts serve as an important measure for assessing the significance of an RCT to promote the dissemination of science. This study attempts to identify the factors associated with the number of times RCTs are cited within the first 24 months since publication.
