Assessing color mismatch in single-shade composite resins for enamel replacement.

Statement Of Problem: Shade selection is a challenge in restorative dentistry. While single-shade composite resins may simplify this process, whether the color mismatch between this composite resin and the substrate is within acceptable levels to ensure successful outcomes is unclear.

Purpose: The purpose of this in vitro study was to assess the influence of background and surrounding shade, thickness, and proximity to the surrounding on color mismatch when shaded and single-shade composite resins are used in the center of an enamel layer.

The role of interface distance and underlying substrate on the color adjustment potential of single-shade composites.

Objective: This study assessed how the distance from the composite interface and the underlying chromatic substrate affect the color adjustment potential (CAP) of two single-shade composites.

Materials And Methods: Cylinder-shaped specimens were created using Vittra APS Unique (VU), Charisma Diamond One (DO), and a shaded (A3) composite. Some single-shade specimens were surrounded by the A3 composite, forming dual specimens.

Background and surrounding colors affect the color blending of a single-shade composite.

This study evaluated the background and effect of surrounding colors on the color blending of a single-shade composite used in a thin layer. Disc-shaped specimens (1.0 mm thickness) were built with the Vittra APS Unique composite surrounded (dual specimens) or not surrounded (simple specimens) by a control composite (shade A1, A2, or A3).

Effects of surrounding and underlying shades on the color adjustment potential of a single-shade composite used in a thin layer.

Objectives: This study aimed to evaluate the surrounding and underlying shades' effect on the color adjustment potential (CAP) of a single-shade composite used in a thin layer.

Materials And Methods: Cylinder specimens (1.0 mm thick) were built with the Vittra APS Unique composite, surrounded (dual specimens) or not (simple specimens) by a control composite (shade A1, A2, or A3).

The effectiveness of the supplementary use of the XP-endo Finisher on bacteria content reduction: a systematic review and meta-analysis.

Objectives: This systematic review evaluated the efficacy of the supplementary use of the XP-endo Finisher on bacteria content reduction in the root canal system.

Materials And Methods: studies evaluating the use of the XP-endo Finisher on bacteria content were searched in four databases in July 2020. Two authors independently screened the studies for eligibility.

Color assessment of resin composite by using cellphone images compared with a spectrophotometer.

Objectives: This study assessed the reliability of digital color measurements using images of resin composite specimens captured with a cellphone.

Materials And Methods: The reference color of cylindrical specimens built-up with the use of resin composite (shades A1, A2, A3, and A4) was measured with a portable spectrophotometer (CIELab). Images of the specimens were obtained individually or pairwise (compared shades in the same photograph) under standardized parameters.

Ultra-low frequency transcutaneous electric nerve stimulation does not affect the centric relation registration.

Objective: To evaluate the influence of ULF-TENS on the displacement of the mandibular condyle and on the repeatability of centric relation (CR) registration of three different techniques: bimanual manipulation (BM), long strip technique, and harmonic centric occlusal relationship (R.O.C.

Comparison of mandibular movements in TMD by means of a 3D ultrasonic system and digital caliper rule.

Objective: To compare the amplitude of mandibular movement measurements obtained by two different methods: the ultrasound JAM system and digital caliper rule in individuals with temporomandibular disorder (TMD) vs.

Method: Sixty individuals, without distinction between sex and age were evaluated: 30 with diagnosis of TMD (RDC/TMD) and 30 controls. Mandibular movements of opening, protrusion, and left and right laterality were measured by means of two Instruments: Digital caliper rule and 3D ultrasonic Jaw Motion Analyzer (JMA-Zebris Medizintechnik, Isny/Allgäu, Germany).

An evaluation of patients' knowledge about perioperative information for third molar removal.

Purpose: Third molar removal is usually accompanied by a high degree of patient anxiety. Lack of knowledge about the procedure is a major contributor to this anxiety. The aim of this study was to investigate the perioperative perceptions of patients who underwent extraction of third molars to assess their concerns during the surgical experience.
