Experience of Dental Caries of Adult Patients in Relation To The Characteristic of Dental Visit and Brushing Behavior In Tikrit City

Aim: Dental decay is a process in which the hard mineral structure of teeth isdissolved. The process produces a cavity on the crown of the tooth or a softeningof the root surface. Without regular dental care people are often unaware of thecondition, whereas those who usually seek dental care for a check-up are morelikely to have dental decay treated in a timely manner The aim of the presentstudy was to determine the caries experience of public dental patients by age, sexwith the type of dental visit and brushing behavior in adults in Tikrit city, Iraq.Subjects and methods: A sample of 1284 individuals(580 males and 704females)with an age range of (18-60 years) attending the teaching dental hospitalof collage of dentistry of Tikrit university and the specialized dental center , wereexamined according to WHO guidelines using DMFT index. Questionnaires wereused to assess the level of dental health attitude among the individuals.Results: The distribution of patients was high at younger age for both sexes.Emergency visit had a higher percentage of patients (82.2%). 63.6% of thepatients brush their teeth two or more. The mean DMFT scores were 7.5 (8.3 forfemale and 6.7 for male). Mean DMFT for both sex increases with age. Thepercentage of decayed teeth (D/DMFT%) was the highest among younger agegroup (60.7% for female and 63.1% for male). There was statistically a highlysignificant difference between age, sex, dental visit type and brushing behaviorand DMFT. Emergency patient did show higher level of decayed and missingteeth while general patient did show higher level of filled teeth. Emergencydental visit had higher percentage of decayed teeth (57.3%) than general dentalvisit (42.5%). One or less brushing patient had higher level of decayed andmissing teeth, while two or more brushing patient show higher level of filledteeth. The percentage of decayed teeth for one or less brushing patients was(62.9%) higher than two or more brushing patients (50.1%).Conclusion: It was concluded that the present study findings for DMFT scores washigher than the global standers according to the world health organization(WHO). Therefore, there is a great need to combine restorative-oriented dentalservices with preventive- oriented dental services in order to improve the oralhealth status of this population.

Salt Sensitivity of the Thermoresponsive Behavior of PNIPAAm Brushes.

We report investigations on the salt sensitivity of the thermoresponsive behavior of PNIPAAm brushes applying the quartz crystal microbalance coupled with spectroscopic ellipsometry technique. This approach enables a detailed study of the optical and mechanical behavior of the polymer coatings. Additional conclusions can be drawn from the difference between both techniques due to a difference in the contrast mechanism of both methods. A linear shift of the phase-transition temperature to lower temperatures with the addition of sodium chloride was found, similar to the behavior of free polymer chains in solution. The thermal hysteresis was found to be decreased by the addition of sodium chloride to the solution, hinting to the interaction of the ions with the amide groups of the polymer, whereby the formation of hydrogen bonds is hindered. The results of this study are of relevance to the application of PNIPAAm brushes in biological fluids and demonstrate the additional potential of the ion sensitivity besides the better known thermosensitivity.

Jordanian adolescents’ health behaviour and school climate

AimThis study was conducted to assess the occurrence of physical activity, nutritional habits, tooth brushing and seat belt use behaviour among adolescent school students in Jordan, and to examine the effect of psychosocial aspects of school on these behaviours.MethodA cross-sectional descriptive correlational design was used to draw a sample of in-school adolescents aged between 11 and 15 years. The final sample included 1166 adolescents from five public and two private schools. Study participants filled in a translated version of the health behaviour in school aged children questionnaire. Descriptive statistics, correlational (point biserial), and bivariate analyses (chi-square tests) were used to analyse the data.ResultsAmong the study sample 34.5% of the adolescents practised exercise outside school hours once a week or less frequently, and only 53.1% of them brushed their teeth more than once a day. Regarding seat belt use, 44.7% of the adolescents used them rarely or never. Concerning carbonated sugary drinks and sweets consumption, about 64% and 83.3% of the adolescents, respectively, consumed them once a day or more often. The percentages of adolescents who never drank low fat or whole fat milk were 43.1% and 38.2%, respectively.ConclusionsThe study concluded that school adolescents do engage in unhealthy behaviour. Psychosocial aspect of schools were associated with students’ physical activity, nutritional habits, tooth brushing and seat belt use behaviours.

Effect of ionic strength and salt identity on poly(N-isopropylacrylamide) brush modified colloidal silica particles

HypothesisThe thermoresponse of poly(N-isopropylacrylamide) stabilised particles is influenced by the presence of salt and is dependent on the concentration, and ions present. The conformation and electrophoretic mobility of core/shell PNIPAM brush modified silica particles is expected to vary as a function of these specific ion effects. ExperimentsThe thermoresponse of PNIPAM brush modified silica particles was investigated via dynamic light scattering and electrophoretic mobility measurements between 5 and 45 °C in the presence of 11 different salt solutions. FindingsSpecific ion effects were observed in the presence of salt solutions for concentrations between 50 and 1000 mM. The temperature response could be mapped to a master curve unlike PNIPAM brush behaviour on planar substrates. The magnitude of brush layer lower critical solution temperature reduction was found to follow the order F− > CH3CO2− > Cl− > NO3− ∼ Br− > I− > SCN− for the potassium series and Na+ > K+ > Cs+ > Li+ ∼ NH4+ for the chloride salts. The electrophoretic mobility of the modified particles in the presence of 100 mM potassium salts increased in magnitude as the brush layer collapsed and also with the chaotropic nature of the anion.

Exploration of brushing behavior among university students in Iran: a qualitative research.

Background Currently, it is estimated that 40% of the Iranian population is less than 20 years old, and in the academic year of 2011-2012 about 4 million students of that age were educated. The general assessment of the outcomes of oral health programs and investigating determinants is substantial for developing future plans of oral health. This study was done with the aim of exploring brushing behavior among university students of Iran to specify and understand the important determinants of oral health behavior. Methods A qualitative research method was used. This study was conducted between August and November 2016 in Shahid Beheshti University. Maximum variation sampling was used among university attendees and 44 students with more than 2 years of study duration were selected to be included in the research. Semi-structured interviews were employed for data gathering. All of the recorded interviews and notes were accurately evaluated and data analysis was performed based on the content analysis. Results As a result of the interview analysis 16 main categories emerged: Religious Beliefs, Perceived Benefits, Perceived Barriers, Habitation, Salience of Behavior, Education, Subjective Norms, Peer Pressure, Observational Learning, Knowledge, Perceived Susceptibility, Perceived Severity, Outcome Expectation, Skills, Perceived Self-efficacy, and Perceived Behavioral Control. Codes of sub-theme and theme were identified in the study. Conclusion This present study provides additional evidence with respect to the religious beliefs and the impact of religious instructions in brushing among students. Salience of brushing behavior has been described as one of the structures in an integrated behavioral model. Despite earlier studies suggesting, that peer pressure only plays a role on children's brushing behavior, our study showed that peer pressure is effective on adults as well.

Behavior of Weak Polyelectrolyte Brushes in Mixed Salt Solutions.

Hydrophilic and hydrophobic weak polybasic brushes immersed in aqueous solutions of mixed salt counterions are considered using a mean-field numerical self-consistent field approach. On top of the solvent quality of the polymer, the counterion–solvent interactions are accounted for by implementing Flory–Huggins interaction parameters. We show that ion specificity within the brush can bring about large changes in conformation. It is found that the collapse transition of hydrophobic, weak polyelectrolyte brushes features an intermediate two-phase state wherein a subset of chains are collapsed in a dense layer at the substrate, while the remainder of chains are well-solvated and strongly stretched away from the it. Besides pH and ionic strength, solvent quality of counterions and the composition of ions in the solvent are important control parameters for the behavior of polyelectrolyte brushes. Increasingly hydrophobic counterions penetrate deeper within the brush and stabilize the collapsed region, while hydrophilic counterions do the opposite.

Brownian Dynamics Simulations of Rigid Polyelectrolyte Chains Grafting to Spherical Colloid

Brownian dynamics simulations are employed to explore the effects of chain stiffness and trivalent salt concentration on the conformational behavior of spherical polyelectrolyte brush. The rigid brush adopts bundle-like morphology at a wide range of trivalent salt concentration. The number variation of bundles pinned on the colloid surface shows a non-monotonic profile as a function of the chain stiffness. The radial distributions of monomers and ions and the charge ratio between condensed ions and monomers are calculated. The charge inversion is observed for the high salt concentration regardless of chain rigidity. Furthermore, the pair correlation functions of monomer-monomer and monomer-salt cation are used to elucidate the aggregated mechanism of the bundle-like structure.

Aspects of the Belousov-Zhabotinsky Reaction inside a Self-Oscillating Polymer Brush.

We have developed a novel polymer brush surface exhibiting autonomous swelling-deswelling changes driven by the Belousov-Zhabotinsky (BZ) reaction, that is, the self-oscillating polymer brush. In this system, the ruthenium tris(2,2'-bipyridine) [Ru(bpy)3] catalyst-conjugated polymer chains are densely packed on the solid substrate. It is expected that the BZ reaction in the polymer brush would be influenced by the immobilization effect of the catalyst. To clarify the effect of the immobilization of the catalyst on the self-oscillating polymer brush, the self-oscillating behavior of the polymer brush was investigated by comparing it with that of other self-oscillating polymer materials, the free polymer, and the gel particle under various initial substrate concentrations. The initial substrate dependency of the oscillating period for the polymer brush was found to be different from those for the free polymer and the gel particle. Furthermore, the oscillatory waveform was analyzed on the basis of the Field-Körös-Noyes model. These investigations revealed that the dense immobilization of the self-oscillating polymer on the surface restricted accessibility for the Ru(bpy)3 moiety. These findings would be helpful in understanding the reaction-diffusion mechanism in the polymer brush, which is a novel reaction medium for the BZ reaction.

Factors affecting tooth brushing behavior in multicultural migrant women

This study was to provide basic data on oral health promotion development model after studying acculturative stress, self-esteem and tooth brushing related behaviors of multicultural migrant women. To gather data, a self-administered questionnaire was conducted on 173 multicultural migrant women. The highest frequency of tooth-brushing a day is 2 times. 64.2% of the respondents brush their teeth before going to bed. As the way of tooth-brushing, 50.3% use the rolling method. The percentage of those who did not receive oral health education was 70.5%, which was high. Also, the acculturative stress was higher if the tooth-brushing frequency was less, the tooth-brushing was not performed before going to bed, the Fones method was used as a way of tooth-brushing, and oral health education was not experienced at all. The self-esteem was higher if the number of tooth-brushing was more, the roll technique was used as a way of tooth-brushing, and oral health education was experienced. The factors influencing the number of tooth-brushing were age, oral health education experience, and self-esteem. It is necessary to develop an integrated program that provide systematic education and manage it continuously in order to increase knowledge of oral health.

To Brush or Not to Brush: Product Rankings, Customer Search, and Fake Orders

“Brushing---the practice of online merchants placing fake orders of their own products to artificially inflate sales on e-commerce platforms---has recently received widespread public attention. On the one hand, brushing enables merchants to boost their rankings in search results, because products with higher sales volume are often ranked higher. On the other hand, rankings matter because search frictions faced by customers narrow their attention to only the few products that show up at the top. Thus, fake orders from brushing may affect customer choice. We build a stylized model to understand merchants’ strategic brushing behavior and its welfare implications. We consider two competing merchants selling substitutable products (one of high quality, the other of low quality) in an evolutionary sales-based ranking system that assigns a higher ranking to a product with higher sales. In principle, such an adaptive system improves customer welfare relative to a case in which products are randomly ranked, but it also triggers brushing as an unintended consequence. Since the high-quality merchant receives a favorable bias in the sales-based ranking, he mainly has a defensive brushing incentive, whereas the low-quality merchant mostly has an offensive brushing incentive. As a result, brushing is a double-edged sword for customers. It may lead customer welfare to be even lower than what it would be in a random-ranking system, but in some other cases, it can surprisingly improve customer welfare. If brushing is more difficult for merchants (e.g., due to tougher regulations), it may make customers worse off as it attenuates brushing by the high-quality merchant but induces the low-quality one to brush more aggressively. If search is easier for customers (e.g., due to improved search technologies), it can actually hurt them as it may disproportionately discourage the high-quality merchant from brushing.

Behavior of Spherical Poly(2-acrylamido-2-methylpropanesulfonate) Polyelectrolyte Brushes on Silica Nanoparticles up to Extreme Salinity with Weak Divalent Cation Binding at Ambient and High Temperature

The colloidal stability of nanoparticles (NPs) stabilized by grafted polyelectrolyte (PE) brushes in concentrated divalent ion solutions, at either ambient or high temperature, is of interest in a wide variety of applications including medicine, personal care products, oil and gas recovery, reservoir imaging, and environmental remediation. Previous attempts to determine the length of PE brushes at these conditions have been limited by lack of colloidal stability particularly when divalent ions form complexes with the charges on the brushes. We find that brushes of highly acidic strong PE poly(2-acrylamido-2-methylpropanesulfonate, AMPS) end-grafted to silica NPs provide colloidal stability at salinities up to 4.5 M CaCl2 or NaCl. Thus, the brush behavior could be studied with dynamic light scattering (DLS) and the electrophoretic mobility by phase analysis light scattering (PALS) from the salt-free condition to the extreme salinities of 4.5 M. In monovalent NaCl solutions, the highly extended poly(AMPS) b...

Experience of maintaining tooth brushing for children born with a cleft lip and/or palate

BackgroundChildren with a Cleft Lip and/or Palate (CL/P) have been reported to have poorer oral health than those without the condition. The consequences for these children can be particularly problematic due to implications for future treatments. Tooth brushing is an important behaviour contributing to children’s oral health, but is under researched in the CL/P population. The aim of the study is to explore the experience of maintaining tooth brushing among children in the United Kingdom (UK) with a CL/P and their parents.MethodsSemi-structured interviews were carried out with twenty-two parents and sixteen children with a CL/P (5-11 years), recruited at a cleft centre in the UK. Thematic analysis was used for data analysis.ResultsThree key themes were drawn from the qualitative data: first, parents of children with a CL/P generally had strong motivation to look after their children’s teeth but children’s motivation was inconsistent. Second, parents were primary enablers of children’s tooth brushing behaviour, often employing approaches adapted to their child’s characteristics to encourage tooth brushing. Third, a range of obstacles were encountered by parents and children in maintaining regular tooth brushing behaviours. They reported obstacles such as issues related to CL/P, ‘forgetting’ and childhood illness.ConclusionsThe paper suggests that parents of children with a CL/P need support to enact their intention to maintain regular tooth brushing and prioritise tooth brushing within the context of demanding and dynamic family life.

Strong Stretching of Poly(ethylene glycol) Brushes Mediated by Ionic Liquid Solvation.

We have measured forces between mica surfaces coated with a poly(ethylene glycol) (PEG) brush solvated by a vacuum-dry ionic liquid, 1-ethyl-3-methyl imidazolium bis(trifluoromethylsulfonyl)imide, with a surface forces apparatus. At high grafting density, the solvation mediated by the ionic liquid causes the brush to stretch twice as much as in water. Modeling of the steric repulsion indicates that PEG behaves as a polyelectrolyte; the hydrogen bonding between ethylene glycol and the imidazolium cation seems to effectively charge the polymer brush, which justifies the strong stretching. Importantly, under strong polymer compression, solvation layers are squeezed out at a higher rate than for the neat ionic liquid. We propose that the thermal fluctuations of the PEG chains, larger in the brush than in the mushroom configuration, maintain the fluidity of the ionic liquid under strong compression, in contrast to the solid-like squeezing-out behavior of the neat ionic liquid. This is the first experimental study of the behavior of a polymer brush solvated by an ionic liquid under nanoconfinement.

Understanding flexible abrasive brush behavior for double disk magnetic abrasive finishing based on force signature

The Double disk magnetic abrasive finishing process (DDMAF) poses better finishing characteristics while finishing paramagnetic thin work piece, when compared to plain magnetic abrasive finishing. This is due to the significant change in the behaviour of the flexible magnetic abrasive brush (FMAB) formed in two cases under similar conditions. Observing and comparing the behaviour of FMAB in action visually is a difficult task. However, FMAB average behaviour can be understood by observing the force signature. Thus present work aims at developing a setup that can be used to capture force signature for the two cases and then understand the FMAB behaviour. The present work present the FMAB force signature obtained while performing finishing with MAF with single disk and double disk. The force signature and the basic magnetic principle have been used to understand the FMAB behaviour and thus understand implications on the finishing process.

Some of the Strongest Predisposing Factors on the Behavior of Tooth Brushing among Iranian School Age Children

Background Oral Health is a criterion for general health. Oral diseases have a chronic process as well as multifactorial nature. Predisposing factors are the strongest factors in behavior formation at personal level. The aim of this study was to determine the strongest predisposing factors affecting oral health behavior among Iranian school age children. Materials and Methods This descriptive-analytical study was conducted on 441 students (9-12 years old) in Rafsanjan city, Iran. Researcher-made questionnaire was used as data collection tool designed based on the reviewing scientific references, text and qualitative research, consisted of three parts including 8 demographic questions, 8 predisposing factors (Knowledge, Attitudes, Perceived Susceptibility, Severity and Benefits, Subjective Norms, Motivation to Comply and Observational Learning) and checklist of weekly behavior of tooth brushing. Data were analyzed using SPSS version 16.0 software. Results Mean score of majority of constructs, except for Knowledge, were at optimum level. Frequency of tooth brushing behavior of twice and more per day was equal to 66.1%. There was a statistically significant positive relationship between tooth brushing behavior and Knowledge of students (r=0.1, P<0.05). According to multi-criteria regression analysis, Knowledge and perceived severity had the strongest predicting role in daily behavior of tooth brushing. Conclusion Perceived severity and knowledge were most important predisposing factor and predictor of tooth brushing behavior among children. Considering these factors in designing interventions to improve the behavior of brushing is recommended.

Abrasive cylindrical brush behaviour in surface processing

Mechanical disintegration of glass surface layers by the action of composite filaments of a cylindrical brush is a new and unique technology for flat glass frosting. So far, similar tools have been used for metal treatment, e.g. for tool edge grinding or for surface treatment of stainless metal sheets. The technology has a high application potential, and facilitates the creation of new types of products for use in the fields of interior glass, domestic architecture, furniture, and lighting. Firstly, the paper describes the theoretical solutions of the new principle of frosting, and how the acquired knowledge can have a wider applicability in the fields of deburring, grinding of surfaces and edges of metal materials etc. Then, it presents a simulation of the kinetics of a separate filament brush, including an evaluation of the marks formed. Subsequently, the results are verified by laboratory experiments. In the conclusion, we recommend technical conditions for implementing the process of surface frosting.
