Risk Factor Targeted Perioperative Care Reduces Anastomotic Leakage after Colorectal Surgery: The DoubleCheck study.

Objective: The DoubleCheck study aimed to introduce pre- and perioperative interventions minimizing exposure to modifiable risk factors and determine its effect on CAL.

Summary Background Data: Colorectal anastomotic leakage (CAL) is a severe complication. In order to predict and prevent its occurrence, the LekCheck study identified intraoperative modifiable risk factors for CAL: anemia, hyperglycemia, hypothermia, incorrect timing of antibiotic prophylaxis, administration of vasopressors and epidural analgesia.

Management recommendations for invasive dental treatment in patients using oral antithrombotic medication, including novel oral anticoagulants.

Objective: The aims were (1) to search the scientific literature from 2007 to 2012 for guidelines and new studies on the dental management of patients using oral antithrombotic medication; (2) to summarize the articles' evidence and recommendations; and (3) to propose an updated clinical practice guideline for general dentists.

Study Design: A systematic literature search in MEDLINE, Embase, and the Guideline websites, from October 2007 to October 2012, produced articles that were critically evaluated.

Results: The systematic literature search for guidelines yielded 74 citations (MEDLINE, 45; Embase, 22; and the Guideline websites, 7).

Survey response of oral and maxillofacial surgeons on invasive procedures in patients using antithrombotic medication.

The aim was to evaluate the management strategies of Dutch oral and maxillofacial surgeons when performing invasive dental or oral surgery in patients using oral antithrombotic medication (OAM). In November 2009 a survey was mailed to all 213 members of the Dutch Society for Oral and Maxillofacial Surgery. A response rate of 57% was achieved with 79 surveys returned through mail and 38 surveys answered through the Internet.

Pain related to mandibular block injections and its relationship with anxiety and previous experiences with dental anesthetics.

Objective: Anesthetic injections should reassure patients with the prospect of painless treatment, but for some patients it is the main source of their fear. We investigated pain resulting from mandibular block injections in relation to anxiety and previous experience with receiving injections.

Study Design: Patients (n = 230) filled out questionnaires before oral surgery.

Reliability and validity of a continuous pain registration procedure.

Background: Conventional pain rating scales [i.e. visual analogue scales (VAS) or numerical rating scales (NRS)] only provide a summary for different levels of pain felt, while the duration of these levels is not accounted for.

Diagnosis, treatment and prevention of ankle sprains: an evidence-based clinical guideline.

Ankle injuries are a huge medical and socioeconomic problem. Many people have a traumatic injury of the ankle, most of which are a result of sports. Total costs of treatment and work absenteeism due to ankle injuries are high.

Treating dental patients who use oral antithrombotic medication: a survey of dentists in the Netherlands.

Background: For many years, international guidelines have advised health care professionals not to adjust oral antithrombotic medication (OAM) regimens before invasive dental procedures. The authors conducted a study to examine the opinions of Dutch general dentists regarding the dental care of patients receiving treatment with these medications.

Methods: The authors invited via e-mail 1,442 general dentists in the Netherlands to answer a 20-item Internet-based questionnaire that they developed.

The structure of common fears: comparing three different models.

Previous studies showed discrepant findings regarding the factor structure of common fears. The purpose of the present study was to expand on these findings and contribute to the development of a descriptive framework for a fear classification. Using data from the Dutch general population (n = 961; 50.

Non-participation in a randomized controlled trial: the effect on clinical and non-clinical variables.

Studies reporting clinical and non-clinical parameters of participants and non-participants of clinical trials are scarce. In the available studies non-participants were likely to show less favourable outcomes than participants on both socioeconomic parameters as well as on caries experience. However, the impact of non-participation on the total sample of the research population is not established.

[The complexity of the concept oral health-related quality of life].

The methods uses most often for developing and analyzing questionnaires, such as the explorative factor analysis and Cronbach's alpha, presume that psychological constructs are latent (imperceptible) and that there is a reflective-measurement model with the underlying assumption of local independence. Local independence means that the latent variable explains why the variables observed are related. Many questionnaires for measuring oral health-related quality of life are analyzed as if they were based on a reflective-measurement model assuming local independence.

Instrument-order effects: using the Oral Health Impact Profile 49 and the Short Form 12.

Whereas it is well known that the ordering of items can influence research outcomes considerably, very little literature addresses instrument-order effects. Therefore, the aim of this study was to evaluate the effect of changing the administrative order of the Short-Form-12 (SF-12) and the Oral Health Impact Profile-49 (OHIP-49). It was hypothesized that if the SF-12 was administered first, the results would show poorer scores on the SF-12 subscales, as responses would not be restrained to only the oral impacts described by the OHIP-49.

Attitudes towards oral health among parents of 6-year-old children at risk of developing caries.

Objectives: Parental attitudes are likely to play a role in achieving and maintaining a desired level of oral health in children. To be useful in individually delivered caries prevention programmes, parental attitudes should be identified at individual level. Q-methodology has been proved successful in identifying attitudes in a wide range of disciplines but in dentistry Q-studies are scarce.

Value of bitewing radiographs for detecting approximal caries in 6-year-old children in the Netherlands.

Background: When diagnosing caries using clinical judgment only, the prevalence of approximal caries is highly underestimated. Yet, surveys on this topic predominantly included adolescents and young adults.

Aim: To determine the additional diagnostic value of bitewing radiographs in 6-year-old children and to detect approximal dentin caries in the primary dentition.

Patients' and parents' expectations of orthodontic treatment.

Objective: To investigate the expectations of children and their primary care-givers towards orthodontic treatment and to compare the results with those of a UK sample.

Design: A questionnaire survey of children and their primary care-givers attending for their first consultation.

Setting: The Department of Orthodontics at the Academic Centre for Dentistry Amsterdam (ACTA), the Netherlands.

Perceptions of Dutch orthodontic patients and their parents on oral health-related quality of life.

Objective: To test the hypotheses that 1) there is no difference between orthodontic patients' and their parents' reports of patients' oral health-related quality of life, and 2) there are no gender differences.

Materials And Methods: The sample consisted of 182 orthodontic patients (age range, 8-15) and their parents. Respondents were required to complete the Child Oral Health Impact Profile (COHIP).

Model specification in oral health-related quality of life research.

The aim of this study was to analyze conventional wisdom regarding the construction and analysis of oral health-related quality of life (OHRQoL) questionnaires and to outline statistical complications. Most methods used for developing and analyzing questionnaires, such as factor analysis and Cronbach's alpha, presume psychological constructs to be latent, inferring a reflective measurement model with the underlying assumption of local independence. Local independence implies that the latent variable explains why the variables observed are related.

Preparatory information for third molar extraction: does preference for information and behavioral involvement matter?

Objective: The objectives of the present study were to: (1) evaluate the impact of high versus low information provision in terms of anxiety towards third molar extraction (TME) as well as satisfaction with information provision. (2) Investigate how preference for information and behavioral involvement, interacted with the provision of information in terms of satisfaction with information and anxiety related to TME.

Methods: Psychology freshmen completed the Krantz Health Opinion Survey and questions concerning anxiety about TME (pretest).

The Dental Discomfort Questionnaire: the basis of a 'Toothache Traffic Light'.

Aim: Firstly to provide an overview of the combined results of the studies done with the Dental Discomfort Questionnaires (DDQ) and second to present a behaviour checklist, a 'Toothache Traffic Light', based on the DDQ, which could possibly be used to raise awareness for toothache among parents and healthcare providers and to improve communication.

Methods: A total of 652 DDQ were analysed to compare the prevalence of toothache related behaviours between children without caries, children with caries but without toothache, and children with caries and toothache. The children had a mean age of 44.

Young children's Oral Health-Related Quality of Life and dental fear after treatment under general anaesthesia: a randomized controlled trial.

During the past decade the research interest in Oral Health-Related Quality of Life (OHRQoL) has been prospering. This study was performed to test (using a randomized controlled trial design) the hypothesis that young children's OHRQoL improves after oral rehabilitation under general anaesthesia (GA). A further aim of this study was to explore whether dental fear also changes.

Anxiety and pain during dental injections.

Objectives: The aim of this study was to study the relationship between anxiety and pain felt during a dental injection in a sample of 'normal' patients about to undergo 'invasive' dental treatment.

Methods: Duration and intensity of pain during a dental injection were measured within a sample of 247 patients. In addition, data on dental anxiety, fear of dental pain, type of treatment, amount of anesthetic fluid, injection location and the use of surface anesthesia were also collected.

Dental management of patients using antithrombotic drugs: critical appraisal of existing guidelines.

Objectives: The aims were: 1) to identify the guidelines available for management of dental invasive procedures in patients on antithrombotic drugs; 2) to assess their quality with the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument; and 3) to summarize their conclusions and recommendations.

Study Design: Systematic literature search for guidelines in several electronic databases. Retrieved guidelines were evaluated with the AGREE instrument for quality assessment.

Prevalence of dental fear and phobia relative to other fear and phobia subtypes.

The purpose of the present study was to estimate the point prevalence of dental fear and dental phobia relative to 10 other common fears and Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV-TR subtypes of specific phobia. Data were also analysed to examine differences with regard to severity, presence of distressing recollections of fear-related events, gender, and prevalence across age. Data were obtained by means of a survey of 1,959 Dutch adults, 18-93 yr of age.

Burnout development among dentists: a longitudinal study.

Knowledge on the development of burnout among dentists is important for purposes of prevention and intervention. Using a two-wave longitudinal design, this study examined the chronological sequence of the three dimensions of the Maslach Burnout Inventory: emotional exhaustion; depersonalization; and personal accomplishment. Structural Equation Modelling was employed among a representative sample of Dutch dentists to examine the fit of several models proposed in earlier research.

Dutch primary schoolchildren's attitudes toward their dental appearance.

Purpose: This study's purpose was to examine children's attitudes toward dental appearance and compare these with attitudes toward general health, body shape, grades in school, friends, money, and sports. The study also explored whether subjects reporting that they have attractive teeth believed themselves to have higher grades in school, more friends, a slim body shape, and better health than subjects reporting that they have unattractive teeth.

Methods: A sample of 216 9- to 13-year-old Dutch children participated.
