Objectives
To quantitatively and qualitatively assess the characteristics of YouTube videos dealing with Sjögren's syndrome.
Materials & Methods
A comprehensive electronic search was performed for ...‘Sjögren's syndrome' in YouTube. After excluding duplicates, irrelevant videos, and non‐English‐language domains, 70 videos were included for analysis. Videos were classified as useful, misleading, or personal experience. The overall quality of videos was scored according to the Global Quality Scale (GQS). Useful videos were assessed for reliability and comprehensiveness based on two 5‐point scales. Key points of the misleading videos were explored and patients' personal experiences were further investigated.
Results
Thirty‐six videos (51.4%) were classified as useful, 6 (8.6%) as misleading, and 28 (40%) as patient's personal experience. Independent users tend to upload videos with personal experience, while university channels/professional organizations share useful videos with evidence‐based information. Significant difference was observed in GQS among useful, misleading videos, and patient's experiences. The mean reliability, comprehensiveness, and GQS scores of useful videos were 2.5 (s.d.:1.2), 2.6 (s.d.:1.4), and 3.4 (s.d.:1.0), respectively, whereas only six videos (16.7%) were rated as complete vis‐à‐vis content. The most frequently misleading topics were etiology and treatment.
Conclusions
Specialists should refer their patients to validated e‐information resources and actively participate in the development of video‐sharing platforms.
Objectives
To identify the most discussed dental articles on the Web and to assess the association between the intensity of online attention, publication characteristics, and citations.
Materials and ...methods
An Altmetric Explorer search was conducted for articles published in the 91 dental journals included in 2015 InCites™ Journal Citation Report® and mentioned online at all times. The 100 articles with the highest online attention, as measured by the “Altmetric Attention Score” (AAS), were screened for journal title, quartile of impact factor distribution (Q1–Q4), publication date, origin and affiliation of first author, article topic, type, and access. Citation counts were harvested from Scopus.
Results
The top 100 articles presented a median AAS of 119 and were mostly discussed on news outlets, Twitter, and Mendeley. Forty‐one articles were published in Q1 journals, 24 in Q2 journals, 32 in Q3 journals, and three in Q4 journals. AAS was significantly higher in articles of Q2 journals (median AAS = 398, range = 70–513) than in articles of Q1. A weak reverse correlation existed between AAS and time since publication (r = −.25, p < .05). No correlation was detected between AAS and other publication characteristics or number of citations.
Conclusions
Increased social impact of dental articles is not significantly associated with high citation rates.
Purpose
To evaluate the residual surface roughness of 5 common diamond-coated interproximal reduction (IPR) systems after consecutive in vitro applications in relation to system, diamond grain size, ...and instrument thickness.
Methods
IPR was performed on 80 extracted human incisors using motor-driven strips and discs under predefined conditions. The IPR auxiliaries were applied at 5 consecutive sessions of 20 s on intact interproximal surfaces, and the surface profile (R
a
, R
z
, R
max
) was analyzed at baseline and after each session with an optical profilometer.
Results
No overall significant difference in the roughness values was found between systems (
P
= 0.07 for R
a
,
P
= 0.33 for R
z
, and
P
= 0.48 for R
max
). There was a significant average decrease of R
a
, R
z
, and R
max
for all systems for every unit increase in time by −0.171 μm (
P
< 0.001), −3.297 (
P
≤ 0.001), and −2.788 μm (
P
= 0.001), respectively. R
a
, R
z
, and R
max
values increased significantly, i.e., by 0.194 μm (
P
= 0.003), 5.890 μm (
P
= 0.001), and 5.319 μm (
P
= 0.010) as instrument thickness increased by one unit. No significant reductions in R
a
, R
z
, and R
max
were observed across grain sizes (−0.008 μm
P
> 0.05, −0.244 μm
P
> 0.05, and −0.179 μm
P
> 0.05, respectively). There was no evidence of interaction between system and time as the
P
values for R
a
, R
z
, and R
max
were 0.88, 0.51, and 0.70, respectively.
Conclusions
All IPR materials presented significant gradual decrease of surface roughness after repeated applications. There were no significant roughness changes among auxiliaries of different grain sizes. Thinner auxiliaries showed significantly more roughness reduction, possibly requiring more frequent replacement than thick auxiliaries in clinical practice.
Background
The aims of this study were to survey the occurrence of acute medical situations in Dutch orthodontic practice and to examine the self-perceived competence of orthodontists in managing ...acute medical emergencies.
Methods
A self-designed questionnaire was distributed among all 149 Dutch orthodontists attending the spring meeting of the Dutch Society for Orthodontists. The questionnaire was divided into three parts, addressing background information of the orthodontist, precautions against and experiences in acute medical situations, and self-perceived competence of nine common medical emergencies. The statistical analysis was performed using the chi-square test and a multiple logistic regression analysis.
Results
The response rate was 74.5% (105 out of 149). The male to female ratio in this population was 55:50. Mean age of all participants was 46.9 years (SD 10.4 years) with on average 16.7 years of working experience (SD 10.6 years). The most common medical emergency reported by Dutch orthodontists was vasovagal collapse (
n
= 219), followed by acute allergic reaction (
n
= 163) and hyperventilation (
n
= 83). On average, 75% (
n
= 79) of the orthodontists felt competent to handle any acute medical situation with an average occurrence of 0.36 acute medical emergencies per orthodontist per year. Male participants were more likely to send patients towards the emergency department (
p
= 0.049). Moreover, a statistically significant negative correlation was observed between self-perceived competence handling hypoglycemia and years of clinical experience. The longer orthodontists were clinically active, the less competent they felt when encountered with a hypoglycemia (
p
= 0.031).
Conclusions
Medical emergencies may be rare but challenging occurrences in the orthodontic practice. It is strongly recommended for all orthodontists and supporting staff to be trained regularly in the management of medical emergencies and to possess up-to-date evidence-based knowledge. Familiarity with and availability of appropriate drugs and equipment are deemed essential to the management of acute medical emergencies that may arise in the orthodontic practice.
Objective
To assess the qualitative standards of the information distributed via the Internet regarding xerostomia.
Materials and Methods
A comprehensive electronic search was performed for ...‘xerostomia’ and ‘dry mouth’ separately using four search engines. The first 30 results from each search term–engine combination were pooled for analysis. After excluding promotional product sites, discussion groups, video feeds, scientific articles, non‐operative sources, sites with denied direct access through password requirement, non‐English language domains, and online medical dictionaries, 50 Web pages were evaluated in terms of readability, accessibility, usability, and reliability using recommended research methodology the Flesch Reading Ease Score and the LIDA instrument. Author and information details were also recorded.
Results
The results revealed a variable quality of the available Internet information on xerostomia. The Web sites required advanced reading skills, while LIDA scores for accessibility, usability, and reliability ranged from medium to low with average scores extending from 29.1% to 81.3%.
Conclusions
The quality of information about xerostomia among Web sources presents high variability. The existing discrepancy should be alleviated by referring patients to evidence‐based education materials on the Internet. Improvement in xerostomia information e‐resources will contribute to a more advanced quality in oral health care.
The aim of this work was to investigate the published evidence on the comparison of self-perception and diagnosis of orthodontic treatment need. A search of Cochrane Library, MEDLINE, Scopus ...databases, and archives of two orthodontic journals was carried out from January 1966 to August 2011 by the two authors using Medical Subject Heading terms. Studies that investigated solely either self-perception of orthodontic need by laypersons or assessment of orthodontic need by professionals were excluded from the data analysis. The methodological soundness of each study and the aggregate level of evidence were evaluated according to predetermined criteria. Moderate level of evidence, the relatively highest grade, was assigned to 9.1 per cent of the 22 studies, finally included in the data analysis. The overall evidence level provided by the evaluated publications was rated as limited. However, the existing body of evidence indicated a highly variable association between self-perception of orthodontic treatment need and orthodontist's assessment. Future controlled studies with well-defined samples and common assessment methodology will clarify further the relationship between perception of treatment need by laypersons and orthodontists and enhance international comparison and development of health care strategies.
We report a numerical analysis of the scattered light from within the field of view of an eLISA-like full-duplex telescope and, by comparison to a nominal allowable scattered light specification, we ...place constraints on the permissible mirror surface roughness and contamination levels of the mirrors. Our analysis was performed with commercially available stray light software, typically used in non-interferometric imaging telescopes and we do not include polarization or coherent effects. This work therefore represents the early steps towards a more complete understanding of the scattered light budget.
Empirical evidence has indicated that only a subsample of studies conducted reach full-text publication and this phenomenon has become known as publication bias. A form of publication bias is the ...selectively delayed full publication of conference abstracts. The objective of this article was to examine the publication status of oral abstracts and poster-presentation abstracts, included in the scientific program of the 82nd and 83rd European Orthodontic Society (EOS) congresses, held in 2006 and 2007, and to identify factors associated with full-length publication.
A systematic search of PubMed and Google Scholar databases was performed in April 2013 using author names and keywords from the abstract title to locate abstract and full-article publications. Information regarding mode of presentation, type of affiliation, geographical origin, statistical results, and publication details were collected and analyzed using univariable and multivariable logistic regression.
Approximately 51 per cent of the EOS 2006 and 55 per cent of the EOS 2007 abstracts appeared in print more than 5 years post congress. A mean period of 1.32 years elapsed between conference and publication date. Mode of presentation (oral or poster), use of statistical analysis, and research subject area were significant predictors for publication success.
Inherent discrepancies of abstract reporting, mainly related to presentation of preliminary results and incomplete description of methods, may be considered in analogous studies.
On average 52.2 per cent of the abstracts presented at the two EOS conferences reached full publication. Abstracts presented orally, including statistical analysis, were more likely to get published.
This article reviews the present literature on the issues encountered while coping with children with autistic spectrum disorder from the dental perspective. The autistic patient profile and external ...factors affecting the oral health status of this patient population are discussed upon the existing body of evidence.
The MEDLINE database was searched using the terms 'Autistic Disorder', 'Behaviour Control/methods', 'Child', 'Dental care for disabled', 'Education', 'Oral Health', and 'Pediatric Dentistry' to locate related articles published up to January 2013.
Most of the relevant studies indicate poor oral hygiene whereas they are inconclusive regarding the caries incidence in autistic individuals. Undergraduate dental education appears to determine the competence of dental professionals to treat developmentally disabled children and account partly for compromised access to dental care. Dental management of an autistic child requires in-depth understanding of the background of the autism and available behavioural guidance theories. The dental professional should be flexible to modify the treatment approach according to the individual patient needs.
