Evaluation of different decontamination procedures on bond strength to sound and caries affected dentin using "no-wait" universal adhesive.

Background: Current study aimed to evaluate the effect of different decontamination procedures on micro-shear bond strength (μSBS) of sound (SoD) and caries-affected dentin (CAD) of two universal adhesives after blood-saliva contamination.

Methods: One hundred and eighty bovine anterior teeth were prepared and allocated into the respective groups according to tested dentin substrates [SoD, CAD], universal adhesives [Clearfil Bond Universal Quick (UBQ), All-Bond-Universal (ABU)], adhesive contamination stage [none, contamination before and after adhesives light-curing], and according to decontamination procedures [no decontamination, water rinsing, adhesive rebond, Ethylenediaminetetraacetic acid (ETDA) and chlorhexidine (CHX) application]. Universal adhesives were applied according to manufacturer instructions in self-etch (SE) bonding mode.

Radium radioactivity in soil profiles following long term irrigation with high radioactivity fossil groundwater.

High radioactivity in a relatively saline confined aquifer water in different locations of the Disi area (South East of Jordan) was reported by some authors who recommended further investigation on the impact of that water on irrigated soils. Five well water samples (jointly used for irrigation and drinking) and 28 surface and subsurface soil samples from five profiles were collected from that area for the purpose of this study. Selected mineralogical, chemical, and physical properties of the soil samples were determined.

Effect of Arginine and nano-hydroxyapatite application on the hypersensitivity and color change of bleached enamel: A randomized controlled clinical trial.

Background: To evaluate the effect of 2.5% Arginine and nano-hydroxyapatite (nHA) application on the post-bleaching hypersensitivity (HS) and color change in a randomized controlled trial.

Material And Methods: Sixty-four participants were randomly allocated to four groups (n=16) according to the investigated desensitizing agents (UltraEZ gel, experimental 2.

Key socio-demographic characteristics of children and adolescents with gender dysphoria: A British Isles surveillance study.

The present research used linked surveillance systems (British Paediatric Surveillance Unit; and the Child and Adolescent Psychiatry Surveillance System) over a 19 month period (1 November 2011-31 May 2013) to notify of young people (4-15.9 years) presenting to secondary care (paediatrics or child and adolescent mental health services) or specialist gender services with features of gender dysphoria (GD). A questionnaire about socio-demographic, mental health, and GD features was completed.

Medium-term health and social outcomes in adolescents following sexual assault: a prospective mixed-methods cohort study.

Purpose: To describe medium-term physical and mental health and social outcomes following adolescent sexual assault, and examine users' perceived needs and experiences.

Method: Longitudinal, mixed methods cohort study of adolescents aged 13-17 years recruited within 6 weeks of sexual assault (study entry) and followed to study end, 13-15 months post-assault.

Results: 75/141 participants were followed to study end (53% retention; 71 females) and 19 completed an in-depth qualitative interview.
