The main objective of this study was to compare the effectiveness of a low cost toothbrush ("monoblock") to that of a conventional toothbrush with and without addition of dentifrice with respect to the removal of dental plaque. Thirty-two 4- to 6-year-old children took part in this study: they were evaluated under four experimental conditions defined by the combinations of the values of two factors, toothbrush (conventional or monoblock) and use of dentifrice (with or without). The effectiveness of the treatments was defined in terms of the reduction of a bacterial plaque index evaluated before and after toothbrushing. No statistically significant differences were detected between the two types of toothbrushes with respect to the reduction of the bacterial plaque index. Similarly, there were no statistical evidences that the use of dentifrice improves the mechanical control of dental plaque. These results are important from a public health point of view, specially in developing countries, where the dissemination of educational and preventive techniques of low cost are fundamental.

The Impact

Background: Dextran is a branched polysaccharide and one of the polymers, present in the biofilm matrix. The dextran plays a perilous role in dental plaque formation, which is involved in the development of some common oral diseases like dental caries. The dextran-hydrolyzing enzymes are under investigation to treat and manage the dental plaques. Aims and Objective: The present study reporting the preliminary observations on the effect of the use of dextranase-containing mouthwash (DMW) on dental plaque and oral health. Materials and Methods: DMW was prepared with food-grade dextranase, preservatives, gellingagents, and water as detailed. Four weeks of experimental design was employed in fourteen healthy volunteers. The selected volunteers were recommended to use DMW for at least twice a day. The plaque index (PI), probing depth (PD), gingival index (GI) and bleeding on probing (BOP) of the volunteer's teeth have been assessed before and after four weeks of DMW use. Results:The volunteers were insisted to use a DMW solution twice a day for four weeks. The PI, PD, GI, and BOP was measured before and after the treatment. The plaque index of the subject at baseline and after treatment was 2.22 ± 0.48, and 1.88 ± 0.50, respectively. PI was significantly reduced after the use of DMW solution for four weeks. The value of PD was 2.00 and 2.00 at baseline and after the use of DMW, respectively. The value of PD was not changed when compared to the baseline values. The sensory evaluation of DMW was performed using questionnaires. Conclusion: The preliminary study results suggested that the use of DMW solution for four weeks (twice a day) notably reduced the PI without any change in PD. However, GI and BOP values were not affected after the use of DMW. The participants, based on the sensory evaluation, accepted the prepared DMW solution. Additional detailed research on the impact of DMW on oral hygiene is needed to confirm the beneficial effects of DMW.

The crisis of Australian-Russian relations after Russia’s annexation of Crimea in March 2014 and the set of factors that caused it have received little attention from scholars of international affairs. The article contributes to addressing this research lacuna. It examines the 2014–2015 crisis in bilateral relations from the point of view of both Moscow and of Canberra. The author analyses the evolution of these relations before 2014 to understand whether the Ukrainian crisis was the cause of their sharp deterioration in 2014–2015, or it only accelerated the process that began much earlier. He demonstrates that Australia had no close political and economic ties with Russia, and the two countries did not consider each other as priority partners. The article finds that in 2014–2015 the Kremlin did not take into account a number of factors, such as very limited interest of Australia in commercial exchanges with Russia, Canberra’s growing suspicions about Moscow’s foreign policy intentions and view of Russia as a revisionist power (especially after the 2008 Russia-Georgia war), a strong sense of solidarity with the West among Australia’s political elites, and Russia’s increasingly worsening public image in Australia, that negatively affected Canberra’s stance towards the Kremlin even before 2014, and which greatly contributed to the crisis in bilateral relations. As for future development, the author identifies two factors that may have a negative impact on Russian-Australian relations: 1) rising energy demand in China and India, making Russia and Australia potential competitors in Asia’s gas markets; 2) a too close rapprochement of Moscow with Beijing, fraughtwith the risk of embroiling Russia in a web of conflicts in the Western Pacific.

Abstract Dental plaque is formed from biofilm that coats the surface of the teeth and is an indicator of dental and oral hygiene. One way to control plaque is by brushing your teeth. Herbal toothpaste is expected to inhibit plaque growth because it is related to the ability of herbal ingredients to inhibit microbial growth. This study aims to determine the comparison of the effectiveness of herbal and non-herbal toothpaste on reducing the plaque index in children aged 15-18 years (WHO). This type of research is  experimental with pretest-postest group design on 30 respondents obtained by total sampling method and divided into 2 groups. A total of 15 respondents in the first group used herbal toothpaste and 15 respondents in the second group used non-herbal toothpaste. The plaque index is measured based on the Loe and Silness plaque index. Paired t test was used to determine the difference in dental plaque index before and after treatment. The results showed that there were significant differences in the dental plaque index on the use of herbal and non-herbal toothpaste for children aged 15-18 years.

The goal of this work was to test a patented pruning harvester and a mobile pelleting system specifically designed for the vineyard agripellet chain. Biomass was characterized before and after storage and after the pelleting stage. The performance, the fuel consumption, and the work quality of the harvester were assessed together with the productivity and the power consumption of the mobile pelleting system. Production costs of pellet were estimated for the whole logistic chain, considering two scenarios: Storage and pelleting directly at the farm site or at a dedicated location at variable distance from the fields. For comparison, the direct production of chips without pelleting was considered. Results indicate that harvester performance was quite good and comparable with commercial solutions; the chips produced exhibited excellent storage performance, allowing direct pelleting without forced drying; the pellet quality was good comparable with that produced from forestry biomass. From an economic point of view, in-field pelleting was the most cost-effective solution, with a good margin of profit up to 57€ t−1; on the other hand, when transport to an intermediate storage center is necessary, profit margin reduces gradually and fades off at an average 50 km distance from the fields.

Introduction: Most of the mentally retarded children may not brush their tooth correctly. They need parents or caregivers to help and supervise the tooth brushing process to reduce the accumulation of dental plaque which may lead to oral diseases. This research was aimed to analyse the most effective toothbrush between parents’ toothbrush and regular toothbrush on children with mental retardation. Methods: This research was quasi-experimental with the blind method. Twenty-nine students with mental retardation consisted of boys and girls of YPLB Cipaganti Special Needs School-C (SLB-C) were selected with total sampling. Each individual was divided randomly and being given the parents’ toothbrush and regular toothbrush. Parents were responsible for brushing their children’s teeth during the period of the study. Plaque scoring was performed on the seventh day. The wash-out period was initiated after the seventh day for one week. Each group was given a different toothbrush from their first toothbrush, and the plaque scoring was performed on the first and seventh day. Plaque scoring was assessed using the Greene Vermillion Index. The data obtained were tested with the Wilcoxon and Mann-Whitney tests. Results: An average difference of plaque index before and after using parents’ toothbrush was 0.3, and the average difference of plaque index before and after using a regular toothbrush was 0.4. There was no significant difference in plaque index changes between these two toothbrushes (p-value > 0.05). Conclusion: Two types of toothbrushes, which are parents’ toothbrush and regular toothbrush are able to reduce plaque.

Plaque on the teeth of smokers comes from cigarette smoke tar that settles on the surface of the teeth and roots of the teeth, causing the tooth surface to become rough and easier to stick with food debris and germs that will react making it easier for plaque to form. This study was aims to determine the safety and effectiveness of removing plaque in palm shell activated charcoal toothpaste with a concentration of 12% calcium carbonate combination of 25%. The content of calcium carbonate as an abrasive against the dental plaque of active smokers. The method used was measurement the plaque index score according to Turesky before and after using toothpaste on 20 panelists of active smokers. The decrease in plaque index in the use of toothpaste by using Wilcoxon's non-parametric statistical test, namely P = 0.000 (Sig <0.05). The results showed that toothpaste in the first week was able to reduce dental plaque by 59% compared to positive control by 45% and without activated charcoal by 34%. Toothpaste and positive control in the second week were able to remove dental plaque by 100%, while toothpaste without activated charcoal and calcium carbonate was only able to remove dental plaque by 68%. It can be concluded that palm shell activated charcoal toothpaste with a concentration of 12% combined with 25% calcium carbonate is safe and effective in removing plaque on the teeth of smokers.Keywords: dental plaque, efficacy, palm shells

The work presents a study through electroanalytical procedures for the determination of metals in gasoline samples. The determination of metals in fuel is an issue of environmental relevance because it believes that these elements can be released into the atmosphere causing damage to the environment and health. Also when present outside the established acceptable limit, the reactivity of these elements may directly imply the quality of the fuels. Thus, the use of low cost and efficient techniques such as electroanalytic are shown as a viable option for this purpose. The access to the metals by voltammetric techniques was only possible after the acid digestion of the samples and two digestion procedures were evaluated (Digestor Block and Microwaves) in different acid purities. The comparison between the two digestion systems (open and closed) using the same experimental conditions showed that the digestion in the closed system presented better results, due to the lower risk of contamination of the sample. The evaluated procedure presented satisfactory results from an analytical and statistical point of view and, therefore, it was considered adequate for the analyzed matrix.

Background: Fixed orthodontic appliance patients have a high risk to increasing plaque accumulation in tooth surface due to the presence of fixed appliance components. Using mouthwash with antibacterial agent from herbal material can control dental plaque accumulation. Bay leaf (BL) contains active compounds such as essential oil, tannin and flavonoid that have been known as an antibacterial agent. Purpose: The purpose of this study was to determine the effect of rinsing with 60% of BL aqueous decoction to the accumulation of dental plaque in fixed orthodontic appliance patients. Method: This research was an experimental clinical research with pretest and post-test control group design conducted on 20 subjects with age ranged between 18-25 years old. All subjects were undergoing the last stage (finishing) of fixed active orthodontic treatment. The subjects were instructed to rinse with 60% of BL aqueous decoction and 0.2% chlorhexidine as a control. Wash out period that needed between rinsing with 60% of BL aqueous decoction and rinsing with 0.2% chlorhexidine was 7 days. Each mouthwash used routinely for 7 days with same duration and intensity. Plaque scoring was measured before and after each treatment using Orthodontic Plaque Index (OPI). Result: One-way Anova test showed that there was a significant difference in the plaque index before and after treatment between the group of rinsing with 60% of BL aqueous decoction and group of rinsing with chlorhexidine (p<0.05). Conclusion: Rinsing with 60% BL aqueous decoction can decrease the accumulation of dental plaque in fixed orthodontic appliance patients.

Abstract. In a recent paper, Ferrer and Pardo (2014) tested several distribution-based methods designed to assess when test scores obtained before and after an intervention reflect a statistically reliable change. However, we still do not know how these methods perform from the point of view of false negatives. For this purpose, we have simulated change scenarios (different effect sizes in a pre-post-test design) with distributions of different shapes and with different sample sizes. For each simulated scenario, we generated 1,000 samples. In each sample, we recorded the false-negative rate of the five distribution-based methods with the best performance from the point of view of the false positives. Our results have revealed unacceptable rates of false negatives even with effects of very large size, starting from 31.8% in an optimistic scenario (effect size of 2.0 and a normal distribution) to 99.9% in the worst scenario (effect size of 0.2 and a highly skewed distribution). Therefore, our results suggest that the widely used distribution-based methods must be applied with caution in a clinical context, because they need huge effect sizes to detect a true change. However, we made some considerations regarding the effect size and the cut-off points commonly used which allow us to be more precise in our estimates.
