Red Propolis has been shown to be a potent antimicrobial, antinflammatory, antitumoral and antioxidant, however, is less studied against microorganisms and periodontal disease. This study aimed to investigate the antimicrobial, citoxicity properties and control of a induced periodontal pocket in rats of a red propolis mucoadhesive gel -containing chitosan. For this, we used two gels with concentrations of 5% (RPG5%) and 10% (RPG10%) of propolis and were compared with chitosan gel base 5% (CHG), propolis extract 5% (FRP5%) and chlorhexidine 0.12% (CHX0,12%). The products were tested against S. mutans, S. salivarius, S. sanguinis, L. casei, A. actinomycetemcomitans, E. faecalis, P. gingivalis, F. nucleatum, and C. albicans ATCC standards. The Minimum Inhibitory Concentration, Concentration Minimal Bactericidal and agar diffusion tests were performed according to CLSI standards. Ligature induced periodontitis model were used and the gel product were applied in test and control rats group. The results showed that all microorganisms were sensitive to the gel RPG5% and RPG10%. There was a reduction in insertion loss and alveolar resorption in the animals treated with propolis gel. Chitosan appears to have not affected the antimicrobial activity of propolis and there seems to have been a synergism between the products. On the other hand, new tests and clinical trials studies should be performed to confirm these parameters.

Orthodontics and dentofacial orthopedics, the first specialty of dentistry aims for correction of malocclusion, by movement of teeth, orthopedic changes in jaw bones with growth modulation or by ortho-surgical planning for the varied skeletal malocclusion. Rapid Palatal Expansion (RPE) for treatment of maxillary constriction, growth modulation with forward posturing of lower jaw with myo-functional appliances and surgical repositioning of jaw bones with orthognathic surgery results in alteration of the nasal and oral volume. These changes affect the nasal and oral breathing patterns of the patient and may result in correction of Sleep Breathing Disorders (SBD) like Obstructive Sleep Apnoea (OSA). The conventional methods used to study these changes include 2D cephalometry, rhinomanometry etc. However, with the introduction of 3D evaluation technolo-gy of the craniofacial structures, it has helped orthodontist to evaluate these changes in volume. The contemporary methods include CT, CBCT and MRI. One less commonly explored modality in the field of Orthodontics is Acoustic Rhinometry (AR) and Acoustic Pharyngometry (AP), which is a non-invasive, non-ionizing modality to study upper airway in dynamic state. The AP device uses acoustic reflection technology to accurately map out the size, structure and collapsibility of the oral and nasal airway. The efficacy of the AP is found to be comparable with that of 2D Cephalometry and 3D modalities like CT, CBCT & MRI. This aim of this paper is to highlights the principal, use and importance of AP in the field of orthodontics and to advocate the use of this modality in ortho-dontic practice and training.

Background: Dental anxiety has been reported to lead to avoidance behavior and cause a delay in regular or necessary dental treatment and this also negatively affects dental health. However, the problem remained rarely investigated in our setting and at the national level. This study aims to assess the prevalence of dental anxiety and associated factors among dental clinics of Ayder comprehensive specialized hospital and Mekelle hospital. Objectives: To assess the magnitude of dental anxiety and associated factors among dental clinics of Ayder comprehensive specialized hospital and Mekelle hospital, Mekelle, Tigrai, Northern Ethiopia, 2019. Methods: An Institutional based cross-sectional study design was conducted to assess the prevalence of dental anxiety. The study was conducted from September 2019 to November 2019 on a total sample size of 236. A systematic random sampling technique was used to select participants. A Farsi version of the MDAS questionnaire was used to collect the data. The data collected was entered into a computer for analysis mainly using Statistical Package for Social Sciences (SPSS) for version 21. Then, data were coded, cleaned and some consistency checks were made to assess the quality. It was done by running frequencies and cross-tabulation among various reported cases or variables. Result: Females were 1.89 times AOR=1.896, 95% CI, [1.003-3.585] higher than males to develop dental anxiety. Urban residents were 2.57 times AOR= 2.576, 95% CI, [1.060-6.259] higher to develop dental anxiety than those who reside in rural. Regarding avoidance of dental care, those who avoid dental care were 5.77 times AOR=5.768, 95% CI, [2.107-15.79] higher to develop dental anxiety than those who don’t avoid dental care. In respect of pain, patients who have experienced pain during the recent visit were 2.75 times higher AOR= 2.747, 95% CI, [1.101-6.854] higher to develop dental anxiety than those who didn’t experience pain.Conclusion: The magnitude…

The use of ozone in oral health care is flourishing with the evidence of its effectiveness in treating dental caries. As we know its importance in the troposphere is now witnessed in the dental sphere. There is growing evidence that it can be employed as a therapeutic agent in both medicine and dentistry. Its painless, atraumatic, non-invasive nature and absence of discomfort make it an ideal treatment option especially in the case of paediatric patients where patient’s acceptance is of utmost importance. So, this article summarizes the therapeutic benefits of ozone in dentistry.

Periodontal disease, a common oral health problem is an inflammation of the supporting structure of tooth which is marked up by the association of several risk factors. Smoking tobacco has been conceded as the most influential risk factor among them. No other risk factors can impair to the extent that smoking alone can do in inducing periodontal disease. The more the duration and intensity of smoking, the more the extent and severity of periodontal breakdown. This study was designed to determine the proportion and severity of periodontal diseases among patients who are tobacco smokers attending Dhaka Dental college and Hospital, Mirpur-14. It was a cross-sectional study conducted among 115 participants using pretested semi structured questionnaires. Their periodontal status were examined using CPITN index, gingival index of Loe and Silness and periodontal severity index approved by American Academy Of Periodontology. Data analysis was done using appropriate statistical inferences like frequency, percentage, chi square test etc. Complete data were available of 115 participants of whom all were smokers. Among them, the proportion of periodontal disease was 93% and most of them were affected by moderate periodontitis (33.2%). From the bi-variate analysis done by chi square test, important correlates of periodontal status identified were oral hygiene maintenance practice & preventive knowledge, duration and intensity of smoking, presence of systemic diseases that affect periodontal health, presence of non-smoking tobacco using habit. On the other hand, periodontal severity were significantly associated with age, level of education, monthly income, oral hygiene maintenance practice and preventive knowledge, duration and intensity of smoking, presence of non-smoking tobacco using habits. In stead of having no significant relationship with periodontal status and severity, proportion of the disease was highest (82.6%) among current smokers as well as the cases of severe periodontitis were also highest (18.3%) among them. Proportion of periodontal…

Food for human and feed insecurity livestock is integrated systems that have been foe small holder farmers in Ethiopia in general and study area in particular. To reduce this problem this research was conducted with objectives of promoting and popularize improved lowland sorghum technologies and to create awareness through giving training and enhance stakeholders participation. A total of fifteen (20) trial farmers were selected from two potential sorghum growing kebeles of Dire Dawa administration and one from Harari region rural areas. Four FRG having 60 farmers was established. Two improved sorghum varieties (Melkam and Dekaba) were replicated on the plot of 20mx20m. Training on which a total of 78 participants took part were organized at research sites. Lowland Sorghum varieties were evaluated based on their early maturity, yield, Disease tolerance, seed color, seed size, biomass, and stalk and food test. The yield performance of the improved varieties (Melkam and Dekeba) were 26.58 and 26.44 qt/ha at Dodota, 28.24 and 26.78 qt/ha at Bishan Bahe respectively. The average yield performance of Melkam somewhat higher than Dekaba at both location but statistically no significant difference between two improved varieties across the locations and the biomass/stalk was high which helps for livestock feed. Thus, Melkam variety preferred well for these benefits over dekeba. Therefore, it is recommended that government, nongovernment and other stakeholders should popularize to reach large small holder farmers in similar agro-ecology.

Normally the level of nutrition status of School children in Sri Lanka is not favorable. The Situation is worst in the areas affected by ethnic conflict. Main objectives of this research were studying the current nutritional conditions and contributory factors that have been forced for this situation and remedial measures which could be adopted to correct the situation then we selected primary schools Childrens are from five schools in affected areas. They are Karadiyanaru Maha Vidthiyalayam, Ellupattichenai ambal Vidthiyalayam, Pankudavale Roman Catholic Vidthiyalayam, Kiththul Srikrishna Vidthiyalayam, Pullumalai Roman Catholic Vidthiyalayam. Were selected for this study and multi stage sampling method was used. Samples were randomly selected for areas and Data’s were collected in the form of interview schedule and dietary survey questionnaires. To find out the relationship between contributory factors and nutritional conditions, regression analysis method was used. Survey findings reported that there was a positive relationship between nutrition conditions and food consumption, income, and good sanitation practices. There was a negative relationship between nutritional conditions, infections diseases and body mass index among the dependents of the family. In case of food consumption (Calorie intake) and infectious diseases, there was a negative relationships between these two factors. Further considering the matter of age limits some differences were observed between standard weight and the normal weights of the targeted group. Having compared with standard values, it was found that 38% of school children were stunted, 42.24% were under weight. 20% were wasted there for it can be concluded that the nutritional status of school children in the selected school is poor. Thus immediate attention should be paid to correct the situation.

The grassland pasture of low nutritive value, feeds and climatic factors had led to various responses in blood indices. Cocoa pod and cassava pulp are part of agro-industrial by products that could be used as ruminants feed. The serum lipid profile of West African Dwarf does and kids fed dietary combinations of cocoa pod, cassava pulp and Acacia leaf silage was evaluated in this study using 20 West African Dwarf (WAD) does aged 12-13 months with average body weight of 14.35±0.21kg and kids of 2.5±0.00kg. They were divided randomly into five treatment groups and each treatment consisted of 4 goats per replicate and thereafter subjected to completely randomized design for 90 days feeding trial. The diets contained four levels of fermented cocoa pod at 0, 5, 10, 15 and 20 and cassava pulp at 60, 55, 50, 45, 40 percent levels respectively while 40% cut across the groups. Results showed that combinations of the silage had significant (p

Background: Bibliometrics is a completive method of research and analyses useful to understand the collective contributions of a given scientific community. The detail of the quantity (productivity) and impact as a surrogate marker of quality can shed light on what we have done (number of articles) and how we impact others (citations). It also shows the direction the community can take for further research, guided by its shortcomings and successes. The publications of Latin American medical institutions on brain neoplasms have never been studied. Objective: Analyze a clinical and experimental approach, identifying core journals, type of article, increase of published material with time, number of citations. Additionally, we identified the most researched topics involved in brain tumor literature. Material and methods: We harvested the articles published by at least one author from the Instituto Nacional de Neurología y Neurocirugía from Mexico from its inception in 1964 to 2020. Key bibliometric parameters, as the journal of publication, type of paper, number of articles, and citations were recorded. Results: In cerebral neoplasms, our institution produced 291 articles (clinical versus experimental: 227 vs. 64). With a modest productivity before 2000, the production had increased 8-fold by 2019. The main topic is glioblastoma, also with the highest number of citations. Researchers prefer to conduct original investigations rather than subject reviews. Most papers were published in Archivos de Neurociencias (institutional journal produced in Spanish), most papers published in English were in the Journal of Neuro-Oncology. Discussion: Productivity had an encouraging growth in the last decade, but more emphasis should be given to target international journals, which offer a high number of readers and citations. Strategies to reach these goals have to be found and should be implemented. Conclusion: Research on brain tumors in Mexico has recently shown buoyancy and we should profit from this inertia…

Mine water damage is a major threat to the safe production of coal mines in China, and how to predict mine water surges scientifically and effectively is an important basis for mine water damage accident prevention and protection of groundwater resources. This paper takes a mine field in northwest China as the research object, comprehensively grasps the geological and hydrogeological conditions of the mine and analyses the causes of coal seam water filling; applies Visual MODFLOW to establish a numerical model of groundwater flow in the study area, and carries out dynamic prediction of mine water influx under natural and artificial boundary conditions respectively based on the method of water conservation and coal mining. The results show that the water influx is significantly reduced under the modified boundary conditions, providing a strong basis for the selection of water-preserving coal mining methods and valuable experience for the mining of coal seams in areas with similar conditions.
