[Minimally invasive caries treatment].

The development of minimally invasive caries treatment has dramatically changed dentistry. Instead of traditional, often invasive methods that resulted in significant loss of healthy dental tissue, this approach focuses on preserving the vitality of the pulp and minimizing tissue loss by delaying and scaling back restorative treatments. This involves the use of modern methods, with selective caries removal with or without indirect (pulp) capping being the norm for treating extensive lesions.

Oral health status of Dutch Armed Forces recruits in the years 2000, 2010 and 2020, a retrospective repeated cross-sectional study.

Background: Studies on oral health status of adults are sparse and rarely include data on endodontic treatment and trauma. In the military, those data are available because recruits are routinely assessed with a clinical and radiological examination at the start of their career. This study aimed to identify differences in oral health status of Dutch Armed Forces recruits between cohorts, departments, sex, age and rank, with DMF-T, endodontic treatment and dental trauma as outcome measures.

Um, so, like, do speech disfluencies matter? A parametric evaluation of filler sounds and words.

The efficacy of remote video-based behavioral skills training and awareness training on public speaking performance.

This study evaluated the efficacy of (a) remote video-based behavioral skills training (BST) with added speech outlines on teaching public speaking behaviors and (b) remote video-based awareness training (AT) on speech-disfluency rates. A multiple-baseline design across speech behaviors was used to evaluate the training. Remote video-based BST and AT were effective at teaching public speaking behaviors and reducing speech disfluencies, respectively, for both participants.

Long term clinical performance of 'open sandwich' and 'total-etch' Class II composite resin restorations showing proximal deterioration of glass-ionomer cement.

Objectives: To compare clinical performance of resin composite posterior Class-II restorations placed with etch-and-rinse adhesive or open sandwich technique using glass-ionomer cement.

Methods: Data on Class II restorations placed by one dentist between 1990 and 2016 were collected from patient files, including caries risk, tooth related variables, applied materials and dates of last check-up visit and restoration placement. Open sandwich restorations were placed before 2001, while after 2001, a total-etch technique using etch-and-rinse 3-step adhesive was used when placing a Class II composite restoration.

Do employees' work schedules put them at-risk? The role of shift scheduling and holidays in predicting near miss and incident likelihood.

Introduction: Using crew scheduling and injury incident data from a Fortune 500 manufacturing company, this study analyzed the effect of consecutive shifts and shifts near holidays on near misses and incidents.

Methods: Logistic regressions were conducted with consecutive workdays, days near holidays, and time of shift as predictors of incident and near miss outcomes.

Results: The logistic regression analysis indicated that working consecutive day shifts increases the probability of an incident occurring, with the fourth consecutive shift resulting in the most risk.

The efficacy of remote video-based training on public speaking.

This study evaluated the efficacy of remote video-based behavioral skills training (BST) on teaching public speaking behaviors to 4 participants. A multiple-baseline design across speech behaviors was used to evaluate the effects of the training. Remote video-based BST was effective at increasing public speaking behaviors for all participants.

[Risk factors for class II dental restoration survival:a practice-based study].

The aim of this practice-based cohort study was to determine the performance and influence of possible variables in class II restorations related to practice, patient, tooth, and restoration. To do this, electronic patient files from 11 general practices in the Netherlands were collected, and 31,472 restorations placed between January 2015 and October 2017 were analysed. The observation time of restorations varied from 0 to 2.

[A PhD completed. Restoration longevity: practice based research in the Netherlands].

Although composite and indirect restorations have been used for many years in oral care, clinical studies of the survival rates of restorations placed by general practitioners are lacking. The most important objective of this doctoral research was to investigate the influence of possible risk factors related to practice/operator, patient and tooth/restoration on the longevity of direct restorations. A large database of electronic patient files of general practitioners within the Practice-Based Research Network Nijmegen (PBRN) enabled us to answer these research questions.

Minimally Invasive Intervention for Primary Caries Lesions: Are Dentists Implementing This Concept?

Contemporary minimally invasive treatment concepts for restorative treatment of primary caries lesions include both delayed intervention and smaller-sized preparations restricted to removal of carious tissue. The aim of this study was to investigate whether these concepts have resulted in a trend towards a more conservative choice made by dentists regarding treatment thresholds and restorative techniques. The results from previously conducted, precoded questionnaires developed by Espelid and Tveit, as well as from a recent Dutch questionnaire, were collected and analysed.

Decision-making of general practitioners on interventions at restorations based on bitewing radiographs.

Objective: The aim of this study was to compare decision-making based on bitewing analysis of restored proximal surfaces by general dental practitioners (GDPs) with diagnossis and clinical decisions made by experts in cariology and restorative dentistry.

Methods: This practice-based study used a database of 7 general dental practices. Posterior bitewing radiographs were selected from the electronic patient files of patients, and 770 cases of proximal restored surfaces were selected.

Phosphorylcholine-coated silicone implants: effect on inflammatory response and fibrous capsule formation.

Introduction: The formation of capsular fibrosis around silicone breast implants is a common complication in reconstructive and plastic surgery. Foreign body reaction-induced infections are quite common because of the hydrophobic surface properties of silicone and are, in addition, considered to be a causative factor of capsular fibrosis.

Methods: In this experimental pilot study, 2 groups of 7 Sprague-Dawley rats were established to evaluate the periprosthetic collagen synthesis after implantation of coated silicone implants.

Comparison of various methods and materials for treatment of skin laceration by a 3-dimensional measuring technique in a pig experiment.

Background: The ability to obtain an objective comparison of scar formations by reproducible and quantitatively measurable results have posed a longstanding problem. This was especially troublesome when conclusions were to be drawn about the materials and methods applied. Two-dimensional methods (photography) gave no plastic impression about the spatial coherences in an examined scar.
