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.

Evaluation of microhardness, sorption, solubility, and color stability of bulk fill resins: A comparative study.

Background: Due to the increasing popularity of bulk fill resins, there is a concern that their components can be leached; this is because these are inserted in a single 4-5 mm increment. This in vitro study evaluated the microhardness, sorption, solubility, and color stability of three restorative bulk fill resins, namely: Filtek Bulk Fill (FBF), Tetric N-Ceram Bulk Fill (TNC), and Opus Bulk Fill (OBF).

Material And Methods: Cylindrical samples were fabricated to be 15 mm in diameter and 1 mm thick (n = 10).

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).
