(2014-01-22)Objective: The aim of the present short-term longitudinal randomized case–control study was to assess the effect of nonsurgical periodontal therapy (NSPT) (with and without oral doxycycline delivery) on glycemic status ... -
The effect of orthodontic adhesive and bracket-base design in adhesive remnant index on enamel
(2015-02-14)Background: The purpose of this study was to identify the effects of bracket-base design and adhesive on adhesive remnant index (ARI) and enamel surface area covered by adhesive. Methods: The sample consisted of 32 ... -
Effect of Ovariectomy-Induced Menopause on The Rate of Orthodontic Tooth Movement: A Systematic Review of Animal Studies
(2019)Background: The menopause may theoretically affect the biochemical events leading to orthodontic tooth movement. Aim: To systematically investigate and appraise the quality of the available evidence from animal studies ... -
Effect of ovariectomy-induced osteoporosis on the amount of orthodontic tooth movement: a systematic review of animal studies
(2021)Background: Understanding the impact of osteopenia and osteoporosis on orthodontic tooth movement could be of benefit to the orthodontist, but research in humans presents practical and ethical problems. The ovariectomized ... -

Effect of poor cooperation between coaching and medical staff on muscle re-injury in professional football over 15 seasons
(2019)Background: Muscle injury is the most common type of injury in football. Previous research has focused on traditional risk factors (eg, age, injury history, muscle imbalance/ inflexibility) contributing to muscle re-injury. ... -
Effect of prior knowledge about treatment on cephalometric measurements
(2022)Objective: We hypothesised that prior knowledge of details for a growth modification treatment influences cephalometric measurements and results in a detectable bias. Design: Observational study. Setting: University ... -
Effect of Resveratrol on Pregnancy, Prenatal Complications and Pregnancy-Associated Structure Alterations
(2023)Abstract: Adverse pregnancy outcomes are considered significant health risks for pregnant women and their offspring during pregnancy and throughout their lifespan. These outcomes lead to a perturbated in-utero environment ... -
The Effect of Rooibos (Aspalathus linearis), Honeybush (Cyclopia intermedia) and Sutherlandia (Lessertia frutescens) on Testicular Insulin Signalling in Streptozotocin-Induced Diabetes in Wistar Rats
(2021)Background: Testicular insulin signalling is altered in diabetic (DM) males. While unravelling the mechanism through which DM exert these detrimental effects, studies have shown the importance of insulin regulation in ... -
The Effect of Sealer Application Methods on Voids Volume after Aging of Three Calcium Silicate-Based Sealers: A Micro Computed Tomography Study
(2022-03)Abstract: During obturation, air voids are undesirable as they may provide shelter for microorganisms or passage for fluids. This study aimed to compare the occurrence of voids between three calcium silicate-based sealers ... -
Effect of Silver Diamine Fluoride (SDF) Solution on the Stem Cells from Human Exfoliated Deciduous Teeth (SHEDs)
(2022)Background: SDF is a solution containing silver, fluoride, and ammonia. Clinically, it is used to arrest the progression of carious lesions in primary teeth. Recent studies have shown that SDF has indirect effect on pulp ... -
