Oxidative stress and kidney injury in trans-radial catheterization.

Oxidative stress is linked to coronary artery disease and is a major mechanism in contrast-induced nephropathy. Trans-radial approach in coronary angiography (CA) with minimized peri-procedural bleeding is expected to reduce acute kidney injury incidence. In the present study, oxidative stress patterns observed in radial CA and their associations with early manifestations of kidney injury are described.

Dental arch spatial changes after premature loss of first primary molars: a systematic review of controlled studies.

Studies investigating dental arch spatial changes following first primary molar premature loss are controversial regarding clinical significance. The purpose of this review was to systematically investigate the relevant literature. Controlled studies investigating changes before and after premature loss of first primary molars were searched in various databases.

Are resin composites suitable replacements for amalgam? A study of two-body wear.

Objectives: Wear resistance is an important property of the dental materials, particularly for large restorations in the posterior regions and for the patients suffering from parafunctional activities. Additionally, the wear resistance of flowable composite resin materials is a clinical concern, although they are popular among dentists because of their easy handling. The aims of the present study were to evaluate the wear resistance of nine composite resins both condensable (G-aenial posterior, Venus, GrandioSO, Tetric EvoCeram, Ceram X duo, Filtek Supreme XTE) and new-generation flowable resin composites (G-aenial Universal Flo, GrandioSO Flow and GrandioSO Heavy Flow) and to compare these results with amalgam.

A retrospective evaluation of the aesthetics of the nasolabial complex after unilateral cleft lip repair using the Tennison-Randall technique: a study of 44 cases treated in a single cleft center.

Introduction: Among numerous techniques that have been described for lip repair, the Tennison-Randall method has gained popularity over time and is preferred by many surgeons due to the predictability of the outcome. This study aims to evaluate the esthetic outcome reached in the nasolabial region following primary lip repair with the use of this method.

Materials And Methods: Forty-four patients with unilateral cleft lip (with or without alveolar cleft) were assessed retrospectively through a photographic evaluation by two clinicians with regard to the aesthetics of the lip and nose separately as anatomical subunits as well as of the nasolabial region as an anatomical complex.
