    Objective: Dental impaction is a very frequent problem. Supernumerary teeth, or hyperdontia, are the presence of additional teeth to the normal series in the either of the dentition. The presence of impacted and/or supernumerary teeth can cause various complications. The objective of the present study was to determine the prevalence of impacted and supernumerary teeth in the North Indian population. Study Design: The panoramic radiographic records of 4750 patients attending the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 were examined for this retrospective study. The ages of the patients ranged from 8 to 72 years, with a mean of 34.6 years. Results: A total of 798 (16.8%) patients presented with 1126 impacted teeth. Impacted canines were the most prevalent (9.7%), followed by impacted premolars (4.3%). Supernumerary teeth (1.6%) and impacted molars (1.2%) were less prevalent. Among the 842 impacted teeth, the most frequently affected teeth were the canines (56.7%), followed by premolars (27.8%), and supernumerary teeth (9.3%), while the prevalence of impacted molars was quite lower (6.2%). Conclusion: The most frequently impacted teeth were maxillary canines and the mesiodens were the most common supernumerary tooth. The early diagnosis of supernumerary and impacted teeth is essential to prevent malocclusion and malalignment of permanent teeth demonstrating the importance of panoramic radiographs in their detection

    Objectives: Lip lesions are a frequent cause of consultation in dentistry, as they comprise a signifi cant proportion of the oral lesions. The aim of the present study was to identify the different lip lesions and determine their prevalence in an Indian population. Material and methods: 5231 patients visiting a Department of Oral Medicine and Radiology were examined for the presence of different lip lesions during the period from October, 2011 to May, 2013. The statistical analysis was done using Chi-square test and p<0.05 was considered to be statistically signifi cant. Results: The age of the patients ranged from 8-70 years with a mean age of 32.6 years. The prevalence of lip lesions was 18.8%. The most commonly diagnosed lesions were those due to infections, which affected 32.6% of the po- pulation, followed by mucocele (29.8%) and premalignant lesions and conditions which were observed in 20.6% of the population. Males were more commonly affected than females. Conclusions: The relatively high prevalence of the lip lesions suggests dental practitioners and health care workers to educate the patients and create more awareness regarding them. The dentists should have adequate knowledge about the etiology, clinical features, diagnosis and management of the lip lesions

    Objectives: Oral submucous fibrosis (OSMF) is a potentially malignant disorder of oral cavity, pharynx and upper digestive tract, characterized by progressive inability to open the mouth. Based on clinical and/or histopathological features, various classifications and grading systems have been put forth till date. The aim of the present study was to study the variance in cheek flexibility in OSMF patients, the observance of which led to the introduction of a new grading for the condition. Material and Methods: The study included 412 patients with OSMF attending to the Department of Oral Medicine and Radiology during the period from December 2008 to June 2013. A detailed history and examination of the patients was performed with special emphasis on measuring cheek flexibility. Statistical analysis was done using Chi-square test and p<0.05 was considered to be statistically significant. Results: The most common etiological factor was tobacco (73.3%). All the patients reported with burning sensation of the mouth and blanching of the mucosa. Malignancy was reported in only 4.6% patients. 60.4% patients showed cheek flexibility of 30mm and above, while 29.6% patients showed cheek flexibility between 20-30mm and 10% patients showed less than 30mm of cheek flexibility. Conclusion: The observations of the present study have led to the proposal of a new grading of OSMF based on cheek flexibility which could assist in the categorization of the condition by the clinicians

    Like several other renewable energy resources, wind energy is also a dilute energy source and has an unpredictable and discrete nature which makes it unreliable as a continuous source of electricity. But from the consumer point of view, the electricity must be continuous and must have standard values to allow healthy operating conditions to the equipment. Non- conventional energy sources have satisfied these needs efficiently but because of their environmental impact there is a demand for technology to harvest energy from renewable energy sources. In order to enhance the continuity of renewable energy sources various energy storage devices are used throughout the world. In today’s date 125 GW of electricity is stored in the various storage devices. They allow storage and utilization of electricity according to the system conditions. Use of controllers enables the smoothening of intermittent nature non- conventional wind energy sources. This paper reviews the various energy storage devices that can be used with non- conventional energy resources to improve their reliability and continuity. An overview of the various control techniques to connect the storage devices is also included

    Social factors influencing diabetes mellitus in adults attending a tertiary care hospital in Nagpur: a cross sectional study

    Get PDF
    Background: Social determinants of the health are the conditions in which individuals are born, grow, live and age. Increasingly, these are being recognized for their relationship to the soaring incidence of diabetes mellitus. So, we conducted a study to find the social factors of diabetes mellitus.Methods: A cross sectional study was conducted in adults having type 2 diabetes in outpatient department of tertiary care institute in Nagpur from July to September 2015. Socio demographic factors, health care access factors, stress related factors and self-care behavior of these patients were studied. Data was analyzed using Epi Info 7.1 software.Results: Out of 140 diabetic patients studied females were predominant (55.71%). Most of them were married (92.85%), were Muslim by religion (47.14%), were from nuclear families, (53.57%) and lower middle class (40%). 50% said that they have health care facilities nearby their house and 50.71% do not get drugs regularly in that health care facility. and only (27.14%) were insured. 64.28% of study subjects said that they were accompanied by relatives to hospital. The financial stress (73.57%) and family stress (72.85%) was more in the patients than work stress (49.28 %). 75.72% and 71.42 % checked their blood sugar levels every 6 monthly and blood pressure every monthly and very less patients kept follow up for complications.Conclusions: Our study showed that in spite of having health care facility nearby, the irregularity of drugs was a major concern. Very less study subjects were insured for their health, this implicates higher stress related factors. They had less compliance towards follow-up of complications of diabetes mellitus

    Objectives: Oral submucous fibrosis (OSMF) is a potentially malignant disorder predominantly seen in the Indian subcontinent due to areca nut, tobacco and their products. The aim of the present study was to compare the efficacy of oxitard and aloe vera in the management of OSMF. Material and Methods: 120 subjects with OSMF were included in the study. The patients were clinico-pathologi - cally diagnosed and divided equally in 2 groups, Group A (oxitard group) and Group B (aloe vera group). Group A was administered 2 oxitard capsules twice daily and Group B was given 5 mg aloe vera gel to be applied topically thrice daily for 3 months. Different clinical parameters were evaluated at regular intervals. Data was analyzed using the Student's paired t test and Chi-square test. P-value <0.001 was considered to be statistically significant. Results: Clinical improvements in mouth opening and tongue protrusion was significant in the oxitard group (p=0.0005). Subjective symptoms of pain associated with the lesion (p=0.0003), difficulty in swallowing (p=0.0000) and speech (p=0.0001) also significantly improved in the Group A. The improvement in burning sensation was not statistically significant between the 2 groups (p=0.002). There was a mild to moderate decrease in the size of the lesion. Conclusions: Though there is no definitive treatment for the condition however, overall assessment of symptoms like mouth opening, tongue protrusion, difficulty in swallowing and speech and pain associated with the lesion showed that oxitard capsules can bring about significant clinical improvements than aloe vera gel in the treatment of OSMF

    Aim: Pulp stones are discrete calcified bodies found in the dental pulp. Sialolithasis is the most common salivary gland disease. The aim of the present study was to determine the relationship between the pulp stones and salivary gland stones. Material and Methods: 196 patients were randomly selected from the out patient department for the study. The periapical radiographs for all patients were evaluated for the presence or absence of the narrowing of dental pulp chambers and pulp canals. The intra oral occlusal radiographs were also evaluated to determine the presence or absence of salivary stones. The results were compared and analyzed using the Chi-square test ( p <0.001). Results: Salivary gland calcifications were detected in 5 patients. 191 patients had pulp narrowing and 118 patients had pulp stones. There was no statistical correlation between pulp narrowing and salivary stones ( p >0.001) and also between pulp stones and salivary gland stones ( p >0.001). Conclusions: However, the incidental findings of salivary gland stones on intra oral occlusal radiographs can pro - vide useful information in the early diagnosis of the condition, but in the present study no significant relationship was found between the presence of pulp stones and salivary gland stones

    Hyperlop Transportation System

    As we know that there are four modes of transportation are, rail, road, water, and air. These modes of transport tend to be either relatively slow (e.g., road and water), expensive (e.g., air), or a combination of relatively slow and expensive (i.e., rail). Hyper loop is a new mode of transport that seeks to change this paradigm by being both fast and inexpensive for people and goods. Hyperloop is also unique in that it is an open design concept, similar to Linux. Feedback is desired from the community that can help advance the Hyperloop design and bring it from concept to reality. Hyperloop consists of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube. The capsules are supported on a cushion of air, featuring pressurized air and aerodynamic lift. The capsules are accelerated via a magnetic linear accelerator affixed at various stations on the low pressure tube with rotors contained in each capsule. Passengers may enter and exit Hyperloop at stations located either at the ends of the tube, or branches along the tube length. In this study, the initial route, preliminary design, and logistics of the Hyperloop transportation system have been derived. The system consists of capsules that travel between Los Angeles, California and San Francisco, California. The total one-way trip time is 35 minutes from county line to county line. The capsules leave on average every 2 minutes from each terminal carrying 28 people each (as often as every 30 seconds during rush hour and less frequently at night). This gives a total of 7.4 million people per tube that can be transported each year on Hyperloop. The total cost of Hyperloop is under 6billionUSDfortwoonewaytubesand40capsules.Amortizingthiscapitalcostover20yearsandaddingdailyoperationalcostsgivesatotalof6 billion USD for two one-way tubes and 40 capsules. Amortizing this capital cost over 20 years and adding daily operational costs gives a total of 20 USD plus operating costs per one-way ticket on the passenger Hyperloop

    The purpose of this article is to describe the development in prosthetic legs. Artificial limbs may be needed for a variety of reasons including diseases, accidents and congenital defects. As the human body changes over time due to growth or change in body weight, the artificial limbs have to be changed and adjusted periodically. This constant need for change or adjustment may become costly if the material used is expensive. This study will emphasis the prosthetic legs by focusing on the socket part as it is often changed and replaced with natural-based bio composites. The results of this study are based on the compatibility of the properties of existing and proposed materials which contribute towards providing alternative materials that are more cost efficient, eco-friendly and yet maintaining the features required for artificial limbs. The findings are expected to help patients or wearers to live independently when they are young, who cannot afford to have this essentially
