Oral disorders, saliva secretion, and oral health ‐related quality of life in patients with primary Sjögren's syndrome
In conclusion, patients with pSS reported higher occurrence of dysgeusia, BST, and halitosis, and demonstrated relatively impaired chemosensory and salivary functions. The patients’ poorer OHRQoL was associated with dysgeusia, BST, and halitosis. (Source: European Journal of Oral Sciences)

Bacterial colonization of resin composite cements: influence of material composition and surface roughness
So‐called secondary caries may develop in the cement gap between the tooth and the bonded restoration. Cement materials with a low susceptibility to biofilm formation are therefore desirable. In the present study, the adhesion of Strepococcus mutans onto three adhesive (Multilink Automix, RelyX Ultimate, and Panavia V5) and three self‐adhesive (Multilink Speed Cem, RelyX Unicem 2 Automix, and Panavia SA plus) resin composite cements was evaluated. Previous studies have failed to evaluate concomitantly the effect of both the composition of the cements and their surface roughness on biofilm formation. The presence of S. ...

Higher expression of WNT5A protein in oral squamous cell carcinoma compared with dysplasia and oral mucosa with a normal appearance
WNT5A is a secreted signaling protein that promotes migration and invasion of oral squamous cell carcinoma (OSCC) cells through activation of non‐canonical WNT signaling. Here, we examined expression of WNT5A, β‐catenin, and E‐cadherin by immunohistochemistry in 21 human diagnostic incision biopsies that each had regions of oral mucosa with a normal appearance adjacent to the affected tissue, dysplasia, and OSCC. We also investigated the effect of recombinant WNT5A (rWNT5A) on expression of the cell‐adhesion proteins E‐cadherin and β‐catenin by western blot analysis. No expression of WNT5A protein was present...

Fracture resistance of zirconia ‐based all‐ceramic crowns after bur adjustment
Intra‐oral grinding is often required to optimize occlusion of all‐ceramic restorations. The effect of burs of different grit size on the fracture resistance of veneered zirconia crowns was investigated in this study. Forty‐eight standardized zirconia copings were produced. The ceramic veneer was designed with a positive ellipsoidal defect on the palatal aspect of the crowns. To simulate adjustment of dental restorations by burs, this palatal defect was removed by use of three different diamond‐coated burs with grit sizes 46, 107, or 151 μm (fine, medium, or coarse, respectively). Each different grit size of bur ...

Bulk ‐filled posterior resin restorations based on stress‐decreasing resin technology: a randomized, controlled 6‐year evaluation
This randomized study evaluated a flowable resin composite bulk‐fill technique in posterior restorations and compared it intraindividually with a conventional 2‐mm resin composite layering technique over a 6‐yr follow‐up period. Thirty‐eight pairs of Class II restorations and 15 pairs of Class I restorations were placed in 38 adults. In all cavities a single‐step self‐etch adhesive (Xeno V) was applied. In the first cavity of each pair, the flowable resin composite (SDR) was placed, in bulk increments of up to 4 mm. The occlusal part was completed with a layer of nanohybrid resin composite (Ceram X mono). In ...

Do traumatic events have more impact on the development of dental anxiety than negative, non ‐traumatic events?
The importance of exposure to traumatic events for the development of dental anxiety has not been investigated. The aim of the present study was to test the hypotheses that individuals who reported having been exposed to a traumatic event [that is, fulfilling Criterion A of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM‐5), for post‐traumatic stress disorder (PTSD)] as the cause of their dental anxiety would report significantly higher levels of dental anxiety, typical trauma‐related (PTSD) symptoms, and greater disturbance of memories involving these events than those who reported being ...

Comparison between universal adhesives and two ‐step self‐etch adhesives in terms of dentin bond fatigue durability in self‐etch mode
This aim of this study was to compare universal adhesives and two‐step self‐etch adhesives in terms of dentin bond fatigue durability in self‐etch mode. Three universal adhesives – Clearfil Universal, G‐Premio Bond, and Scotchbond Universal Adhesive – and three‐two‐step self‐etch adhesives – Clearfil SE Bond, Clearfil SE Bond 2, and OptiBond XTR – were used. The initial shear bond strength and shear fatigue strength of resin composite bonded to adhesive on dentin in self‐etch mode were determined. Scanning electron microscopy observations of fracture surfaces after bond strength tests were also made...

Analysis of organic components in resin ‐modified pulp capping materials: critical considerations
The purpose of this study was to elucidate the organic composition and eluates of three resin‐based pulp‐capping materials in relation to their indications and safety data sheets. Uncured samples of Theracal LC, Ultra‐Blend Plus, and Calcimol LC were investigated using gas chromatography–mass spectrometry (GC‐MS) and ultra‐performance liquid chromatography–mass spectrometry (UPLC‐MS). Identification/quantification of 7‐d leachables of cured samples was performed using GC‐MS for 2‐hydroxyethyl methacrylate (HEMA), 2‐(dimethylamino)ethyl methacrylate (DMAEMA), camphorquinone (CQ), ethylene glycol dime...

Effect of photoactivation on the reduction of composite resin contamination
This study aimed to evaluate contamination in vitro of the internal contents of composite resin tubes in the dental clinics of a higher‐education institution, as well as the effect of photoactivation on the level of contamination. Twenty‐five tubes containing composite resin were randomly chosen (by lottery). From each tube, two samples of approximately 2 mm of composite resin were removed, and then one sample, but not the other, was photoactivated. These samples were plated on Brain–Heart Infusion (BHI), Sabouraud and MacConkey agars, and the plates were incubated at 37°C for 24–48 h. Colony counting and Gram sta...

The factor structure of dental fear
There is limited empirical information as to whether or how stimuli associated with dental fear can be classified into distinct subtypes. The purpose of the current study was to develop a descriptive framework for the classification of dental fear. Data were collected using a survey among Dutch twin families (n = 11,771). The sample was randomly divided into two subsamples of, respectively, 5,920 and 5,851 individuals. An exploratory factor analysis (EFA) was performed on the first subsample to delineate the multidimensional structure of a set of 28 dental‐fear‐provoking objects and situations. The second sample was us...

Three ‐dimensional finite element analysis of zirconia all‐ceramic cantilevered fixed partial dentures with different framework designs
The purpose of this study were: to perform stress analyses using three‐dimensional finite element analysis methods; to analyze the mechanical stress of different framework designs; and to investigate framework designs that will provide for the long‐term stability of both cantilevered fixed partial dentures (FPDs) and abutment teeth. An analysis model was prepared for three units of cantilevered FPDs that assume a missing mandibular first molar. Four types of framework design (Design 1, basic type; Design 2, framework width expanded buccolingually by 2 mm; Design 3, framework height expanded by 0.5 mm to the occlusal su...
