Clinical characterization of stomatitis cases with an epithelial growth factor receptor inhibitor in metastatic colorectal cancer patients: A study of 7 cases and literature review.

Objective: The aim of this study was to report a case series of patients with metastatic colorectal cancer (mCRC) undergoing panitumumab-containing regimens affected by oral lesions and to review the current literature.

Study Design: Electronic medical records of mCRC patients referred to treat mouth sores during the treatment with the anti-epithelial growth factor receptor (EGFR)-panitumumab-were retrospectively reviewed. Patients' characterization, clinical profile of oral lesions, and management outcomes were documented.

Micro-CT and FE-SEM enamel analyses of calcium-based agent application after bleaching.

Objectives: The objective of the present study is to evaluate the effects of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) on bleached enamel.

Materials And Methods: A bleaching agent (35% hydrogen peroxide) was applied, 4 × 8 min on premolar teeth (n = 8). A CPP-ACP paste was applied for 7 days.

In-Office Bleaching During Orthodontic Treatment.

Objective: To demonstrate that it is possible to pursue teeth whitening treatment protocols during orthodontic treatment with no esthetic loss.

Clinical Considerations: Many patients undergoing orthodontic treatment desire to have a straight and well aligned dentition, but also whiter teeth. For many years, it was believed that carrying out a whitening treatment with positioned orthodontic brackets in place would result in localized spots on the enamel labial surfaces of teeth.

Effect of light irradiation on tooth whitening: enamel microhardness and color change.

The aim of this study was to evaluate the influence of light exposure associated with 35% hydrogen peroxide (Pola Office, SDI, Melbourne, Vic., Australia) or 15% hydrogen peroxide (BriteSmile, Discus, Culver City, CA, USA) on the microhardness and color changes of bovine enamel. Experimental groups were Britesmile + Light (BL) (15% hydrogen peroxide + plasm arc; 4 x 20 minutes), Britesmile + No Light (BN) (BL, no light), Pola office + Light (PL) (35% hydrogen peroxide + LED; 4 x 8 minutes), and Pola office + No light (PN) (PL, no light).

Diametral tensile strength and Vickers hardness of a composite after storage in different solutions.

This study evaluated the Vickers hardness (VHN) and diametral tensile strength (DTS) of the composite Z100 (3M ESPE) cured with: Quartz-Tungsten-Halogen light curing unit (QTH) (700mW/cm2- 40 s) and Argon laser (1,000mW/cm2- 10 s). Specimens of 2 mm depth and 8 mm diameter were immersed for 30 days at 37 degrees C in different storage means: water, alcohol, acetic acid, propionic acid and dry (control). The DTS (n = 8) was determined with a crosshead speed of 0.

Bond strength of hard chairside reline resins to a rapid polymerizing denture base resin before and after thermal cycling.

Purpose: This study assessed the shear bond strength of 4 hard chairside reline resins (Kooliner, Tokuso Rebase Fast, Duraliner II, Ufi Gel Hard) to a rapid polymerizing denture base resin (QC-20) processed using 2 polymerization cycles (A or B), before and after thermal cycling.

Materials And Methods: Cylinders (3.5 mm x 5.
