Bacterial Adhesion and In Situ Biodegradation of Preheated Resin Composite Used as a Luting Agent for Indirect Restorations.

Objective: To evaluate surface roughness and bacterial adhesion after in situ biodegradation of the cementation interface of indirect restorations cemented with preheated resin composite.

Methods And Materials: Resin composite blocks (Z250XT/3M ESPE) were cemented to bovine enamel (7 × 2.5 × 2 mm) using preheated microhybrid resin composites: (1) Filtek Z100 (3M ESPE) (Z100); (2) Gradia Direct X (GC America) (GDX); and (3) Light-cured resin cement RelyX Veneer (3M ESPE) (RXV) (n=21).

COVID-19 outbreak: Should dental and medical practices consider uv-c technology to enhance disinfection on surfaces? - A systematic review.

Aims: During the COVID-19 pandemic the search for complementary methods to enhance manual disinfection in dental and medical practices raised relevance. We sought evidence for the addition of ultraviolet-C (UV-C) disinfection to manual cleaning protocols -and whether it improves the logarithmic (log) reduction of surface pathogen colonies.

Methods: This review was registered at the International Prospective Register of Systematic Reviews (PROSPERO) under the number CRD420200193961.

Postoperative sensitivity in posterior resin composite restorations with prior application of a glutaraldehyde-based desensitizing solution: A randomized clinical trial.

Objectives: To evaluate the effect of a glutaraldehyde-based desensitizer on the postoperative sensitivity (POS) in posterior resin composite restorations up to 12 months using a universal adhesive (Tetric N-Bond Universal) with selective enamel etching (SE) or an etch-and-rinse (ER) strategy.

Methods: Class I and class II resin composite restorations (n = 220) at least 3 mm deep were inserted in 55 subjects. The universal adhesive was applied using the SE (self-etch strategy on dentin with selective enamel etching) or the ER strategy, with or without prior application of a glutaraldehyde-based desensitizer (Gluma Desensitizer - GL) to form groups SEGL and ERGL.

Cyclic Fatigue Resistance of Blue Heat-Treated Instruments at Different Temperatures.

The main aim is to evaluate the cyclic fatigue resistance of blue heat-treated instruments with different kinematics. Twenty-four endodontic instruments of the same brand were used for each of three experimental groups: VB (Vortex Blue 40/0.04), RB (RECIPROC Blue 40/0.

Thirty-six-month clinical evaluation of posterior high-viscosity bulk-fill resin composite restorations in a high caries incidence population: interim results of a randomized clinical trial.

Objectives: This study compared the clinical performance of two bulk-fill (BF) and one conventional resin composite in a population with a high caries incidence.

Materials And Methods: A total of 138 class I and II restorations were performed and randomly divided into three groups (n = 46) with equal allocation: Filtek BF (FBF; 3M ESPE), Tetric EvoCeram BF (TBF; Ivoclar Vivadent), and control Filtek Z250 (Z250; 3M ESPE). The evaluations were performed using the USPHS and FDI criteria at baseline and after 12 and 36 months by a previously calibrated evaluator.

Do Helmet Use and Type Influence Facial Trauma Occurrence and Severity in Motorcyclists? A Systematic Review and Meta-analysis.

Purpose: This article consists of a systematic review of the literature, which verified whether the use and types of helmets reduce the occurrence and severity of facial fractures in hospitalized motorcyclists after traffic accidents.

Materials And Methods: Prevalence studies and cohort studies, published in Latin American languages with no restrictions on publication dates, were considered. Two authors independently screened reference lists for eligible articles, assessed them for inclusion criteria, and extracted the data using a specific form.

Clinical Performance of Bulk-Fill Resin Composite Restorations Using the United States Public Health Service and Federation Dentaire Internationale Criteria: A 12-Month Randomized Clinical Trial.

Objective:  This study was aimed to compare the 12-month clinical performance of two full-body bulk-fill resin composites Filtek bulk fill/3M ESPE (FBF) and Tetric EvoCeram bulk fill/Ivoclar Vivadent (TBF) and a conventional microhybrid resin composite Filtek Z250/3M ESPE (Z250) using the modified the United States Public Health Service (USPHS) and Federation Dentaire Internationale (FDI) criteria. Also, the agreement between the two evaluation criteria was evaluated at baseline and after 12 months of follow-up.

Materials And Methods:  A total of 138 class I and II restorations were placed in posterior teeth (split-mouth design) of 46 volunteers following manufacturer's instructions and bonded with a self-etching bonding agent (Clear fill SE Bond/Kuraray).

Detection of Incomplete Root Fractures in Endodontically Treated Teeth Using Different High-resolution Cone-beam Computed Tomographic Imaging Protocols.

Introduction: The purpose of this study was to compare different high-resolution cone-beam computed tomographic (CBCT) imaging protocols in the diagnosis of incomplete root fractures of endodontically treated teeth.

Methods: Twenty single-rooted human teeth were endodontically treated, and an incomplete root fracture was induced. The teeth were scanned with the CBCT unit PreXion 3D (Teracom, San Mateo, CA) operating at 2 different protocols: high resolution/standard (HI-STD) (19 seconds and 512 basis images) and high resolution/high density (HI-HI) (37 seconds and 1024 basis images).

The influence of composite resin restorations and lining on radiographic diagnosis and decision-making: an in vitro investigation.

The objective of this study was to evaluate the influence of resin-based restorations on the interpretation of digital and conventional radiographic images and to correlate the proposed diagnosis with decision-making. Class II cavities were prepared in one of the proximal surfaces of extracted human molars. Teeth were divided into five groups (n = 10) according to the restoratives used: Natural Flow (NF) and Filtek Supreme (FS); Filtek Flow (FF) and FS; Tetric Flow (TF) and FS; Protect Liner F (PLF) and FS; and FS alone.
