Comparison of modified Bass, Fones and normal tooth brushing technique for the efficacy of plaque control in young adults- A randomized clinical trial
2019
Background To compare the anti plaque efficacy of Modified Bass, Fones and Normal brushing techniques in young adults. Material and methods An investigator blinded randomized controlled trial with parallel design was adopted to compare the anti plaque efficacy of three tooth brushing techniques. The study population consisted of 120 dental students aged between 18 and 30 years. Results At the baseline, the mean plaque scores were 0.74 ± 0.39, 0.77 ± 0.34 and 0.98 ± 0.36 respectively, for Modified Bass, Fones and Normal brushing technique. After 24 hours without any oral hygiene activity, the plaque scores increased to 1.04 ± 0.30, 1.11 ± 0.32 and 1.21 ± 0.40, respectively. After 1 week of u…
Spectrophotometric evaluation of dental bleaching under orthodontic bracket in enamel and dentin
2013
Aware of the diffusion capacity of bleaching in the dental tissues, many orthodontists are subjecting their patients to dental bleaching during orthodontic treatment for esthetic purposes or to anticipate the exchange of esthetic restorations after the orthodontic treatment. For this purpose specific products have been developed in pre-loaded whitening trays designed to fit over and around brackets and wires, with clinical efficacy proven. Objective: The objective of this study was to evaluate, through spectrophotometric reflectance, the effectiveness of dental blea - ching under orthodontic bracket. Material and methods: Thirty-two bovine incisors crown blocks of 8 mm x 8 mm height lengths…
Emotions toward cognitive enhancement technologies and the body – Attitudes and willingness to use
2020
While technological development is becoming more integrated into our surrounding environments, it is also moving closer towards the human body. In fact, numerous examples can be seen in which information technology (IT) is being designed not just for use on the body, but also inside it. Technologies dominating this domain can be described as ‘cognitive enhancement technologies’ (CETs). These technologies are intended to enhance people's cognitive capabilities, and can be viewed in the forms of implants, lens, drugs, and then moving outward, smart clothing, watches and physical environments to name some. The present study focused on measuring peoples’ (N=104) emotions towards and willingness…
Pneumococcal histidine triads – involved not only in Zn2+, but also Ni2+ binding?
2018
Polyhistidine triad proteins, which participate in Zn2+ uptake in Streptococcus pneumoniae, contain multiple copies of the HxxHxH (histidine triad motif) sequence. We focus on three such motifs from one of the most common and well-conserved polyhistidine triad proteins, PhtA, in order to understand their bioinorganic chemistry; particular focus is given to (i) understanding which of the PhtA triads binds Zn2+ with the highest affinity (and why) and (ii) explaining whether Ni2+ (also crucial for bacterial survival and virulence) could potentially outcompete Zn2+ at its native binding site. There is no significant difference in the stability of zinc(II) complexes with the three studied protei…
Overweight Adolescents’ Self-Perceived Weight and Weight Control Behaviour: HBSC Study in Finland 1994–2010
2012
Introduction. Overweight and perception of being overweight, may lead adolescent to lose weight. The aim of the present study was to investigate overweight adolescents’ self-perceived weight, body dissatisfaction, and weight control behaviour during 1994–2010 in Finland.Methods. The country-representative, cross-sectional data of 15-year olds were obtained from the Health Behaviour in School-aged Children (HBSC) study, conducted in 1994 (; males: 48%), 1998 (; 49%), 2002 (; 50%), 2006 (; 47%), and 2010 (; 48%).Results. The majority of overweight boys (62–69%) and girls (89–100%) assessed themselves as too fat, and their body image was lower than in nonoverweight adolescents. The highest pre…
Argumentativeness among Selected Finnish and American College Students
1991
Summary.-Compared on the Infante/Rancer Argumentativeness scale, 247 Finnish university students had a significantly higher mean score on argumentativeness as a trait than 155 American university students. No significant difference was noted on the desire to approach arguments, but the American students were significantly more inclined to avoid arguments than the Finnish students. Conceptualized by Infante and Rancer (1982) as a personality trait, argumentativeness contains tendencies to approach and to avoid arguments. Persons with approach tendencies will advocate issues on controversial positions and attack conflicting positions. Those with avoidance tendencies try to stay out of argumen…
Dynamic Force Production Capacities Between Coronary Artery Disease Patients vs. Healthy Participants on a Cycle Ergometer
2020
Background: The force-velocity-power (FVP) profile is used to describe dynamic force production capacities, which is of great interest in training high performance athletes. However, FVP may serve a new additional tool for cardiac rehabilitation (CR) of coronary artery disease (CAD) patients. The aim of this study was to compare the FVP profile between two populations: CAD patients vs. healthy participants (HP). Methods: Twenty-four CAD patients (55.8 ± 7.1 y) and 24 HP (52.4 ± 14.8 y) performed two sprints of 8 s on a Monark cycle ergometer with a resistance corresponding to 0.4 N/kg × body mass for men and 0.3 N/kg × body mass for women. The theoretical maximal force (F 0) and velocity (V…
Striato-amygdaloid transition area lesions reduce the duration of tonic immobility in the lizard Podarcis hispanica.
2002
Neuroanatomical data suggest that the lizard striato-amygdaloid transition area is homologous with the mammalian central amygdala. In order to investigate possible functional similarities, tonic immobility was induced in adult lizards and its duration recorded. Each lizard was then randomly assigned to one of three treatments: (1) bilateral striato-amygdaloid transition area lesions, (2) bilateral dorsal cortex lesions or (3) untreated controls. Three days after trial 1, each lizard was subjected to a second trial and the tonic immobility duration recorded. The mean tonic immobility duration in lizards with striato-amygdaloid transition area lesions was significantly shorter (80.5%; p < 0.0…
Agreement between 2 swept-source OCT biometers and a Scheimpflug partial coherence interferometer
2020
PURPOSE To evaluate the agreement between different parameters obtained with 2 swept-source optical coherence tomography (SS-OCT)-based biometers and 1 Scheimpflug camera with partial coherence interferometry (PCI). SETTING Single center, Oftalvist, Alicante, Spain. DESIGN Prospective case series. METHODS Biometry was performed in 49 eyes using 3 optical biometers: ANTERION SS-OCT, IOLMaster 700 SS-OCT, and Pentacam AXL PCI. Keratometry (K), J0 and J45 vectors, anterior chamber depth (ACD), central corneal thickness (CCT), white-to-white (WTW), lens thickness (LT), and axial length (AL) were measured with each device. Bland-Altman analysis was applied. RESULTS This study comprises 49 eyes o…
