Detection of Mesiobuccal Canal in Maxillary Molars and Distolingual Canal in Mandibular Molars by Dental CT: A Retrospective Study of 100 Cases
Sushma Rathi,Jayaprakash Patil,Prashant P. Jaju
International Journal of Dentistry , 2010, DOI: 10.1155/2010/291276
Abstract: Objective. To detect presence of MB2 canal in maxillary molars and distolingual canal in mandibular molars by Dental CT. Material and Methods. A retrospective study of 100 Dental CTs was done. Axial and paraxial images obtained were used to assess the presence of MB2 canal in maxillary molars and distolingual canal in mandibular molars. Results. The youngest patient was of 11 years while the eldest patient was of 77 years. Males were 58 in number and females were 42 in number. MB2 canals were present in 57 patients and distolingual canal was present in 18 patients. Maximum MB2 canals were present in age group between 51 and 60 years, while distolingual canals were present in age group of 21–30 years. Conclusion. Dental CT allows adequate visualization of variation in root canal morphology and can be important diagnostic tool for successful endodontic therapy. 1. Introduction The maxillary first molar is submitted to frequent endodontic treatment, and moreover, it presents the highest failure rates, often in relation to the presence of a second canal in the mesiobuccal root because the operator fails to detect, debride, or obturate this canal [1–4]. Similarly there is considerable variation in presence of distolingual canal in mandibular molars [1]. A thorough comprehension of the intricate 3-dimensional (3D) configuration of a root canal system is essential for the provision of successful endodontic therapy. Therefore the complex anatomic configuration of the maxillary first molar mesiobuccal (MB) root canal system has long been the subject of considerable scrutiny. The incidence of a second root canal in the mesiobuccal root (MB2) is 56.8%, in the distobuccal root 1.7%, and in the palatal root less than 1% [5, 6]. Frequency of MB2 canal have been investigated by numerous authors using different methods. In vivo clinical studies have included retrospective evaluations of patient records, radiographic assessments, and clinical examinations during endodontic treatment, both with and without the aid of magnification. In vitro laboratory studies have used extracted teeth and have included endodontic access, examination, radiography, scanning electron microscopy, grinding and sectioning, as well as numerous clearing studies using decalcification with India ink and other dyes [5, 7, 8]. Two-dimensional imaging like periapical radiography and panoramic radiography loses the battle for the lack of perception in the third dimension. With advent of Dental CT and Cone beam computed tomography (CBCT) the shortcomings of conventional imaging are overcome as they
ANALYTICAL STUDY OF CURCUMIN CONTENT IN DIFFERENT DOSAGE FORMS CONTAINING TURMERIC EXTRACT POWDER AND TURMERIC OLEORESIN
Rane Rajashree,Gangolli Divya,Patil Sushma,Ingawale Kanchan
International Research Journal of Pharmacy , 2013, DOI: 10.7897/2230-8407.04338
Abstract: Different dosage forms namely tablets, capsules, creams and syrups were analysed for curcumin content, by the well-known spectrophotometric method. Turmeric extract powder was used as a source of curcumin in capsule and tablet formulations. Turmeric oleoresin was used as a source of curcumin in cream formulation. Additionally, syrup formulations containing turmeric extract powder as well as turmeric oleoresin, separately, were also tested for their curcumin contents. Analytical results for curcumin content were found to be satisfactory in tablets and capsules containing turmeric extract powder. Whereas, in case of syrup containing turmeric extract powder, analytical findings for curcumin content, did not meet the expected specifications. However, when turmeric powder was replaced by the same quantity of oleoresin having similar strength, in cream and syrup, the results met the expected values, at the initial stages. But analysis data over a period of 1Year testing, showed declination in the initial findings due to unstability of turmeric oleoresin for long duration.
FEM Based Study of Concentration of Proliferating Cell in Brain Tumor  [PDF]
Sushma Nema, V. P. Saxena
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.38140
Abstract: In this chapter we have developed a deterministic model of growth of abnormal cell concentration in a human subject at different positions. The diffusion-reaction Equation has been applied to satisfy growth dynamics .The whole tumor region is divided into layers which, with the growth of tumor form necrotic, quiescent and region of proliferating of tumor cells. Finite element method for one dimension has been employed for solving the Equations. Here we have taken into account the cellular motility along with proliferative growth ,which is particularly required in case of some of the brain tumors, where motility of gliomas cells differ widely in gray and white matter.
Morbidity trends in Lymphatic Filariasis: Analysis from a tertiary care center in Kerala, Southern India
Sushma Krishna
Global Journal of Medicine and Public Health , 2012,
Abstract: Lymphatic filariasis in India contributes to nearly 40% of the global endemic burden. There is paucity of data regarding the association of chronic lymphatic filariasis with diabetes, coronary heart disease and other comorbidities. Case records over a period of ten years from 2001-2010 were reviewed and 113 diagnosed chronic filariasis cases from 13 districts of the state were identified.Prevalence of each of the morbidity with age and sex association was calculated. A total of 82(72.6%) of them were in the age group of 60-85 years. Hypertension was noted in 48, type II diabetes in 46 and coronary artery disease in 43. Filariasis had a significant association with type II diabetes mellitus and coronary artery disease (p value< 0.05). Secondary infection. of leg ranging from cellulitis to gangrene was seen in 33(29.2%). Lymphatic Filariasis may be linked as an inclining factor for the development of type II diabetes mellitus and coronary heart disease over 60 years. Secondary leg infections continue in diabetic patients. The immuno- modulatory mechanisms involved needs to be explored.
Application of Ozone Therapy in Dentistry
Sushma Das
Indian Journal of Dental Advancements , 2011,
Abstract: Ozone therapy has successfully being used in the medical field for treatment of various diseases for more than 100 years. The versatility of ozone therapy, its unique properties, noninvasive nature, absence of side effects or adverse reactions were responsible for its wide spread use. This review of literature is an attempt to summarize its therapeutic potential in dentistry and its possible clinical application in future.

MORPHOLOGICAL METHOD, PCA AND LDA WITH NEURAL NETWORKS-FACE RECOGNITION
Sushma Jaiswal
Journal of Global Research in Computer Science , 2011,
Abstract: The problem is, these forms of machine identification and verification aren’t very secure, because they can be given away, taken away, or lost and motivated people have found ways to forge or circumvent these credentials. The ultimate form of electronic verification of a person’s identity is biometrics; using a physical attribute of the person to make a positive identification. So we need a system, which is similar to the human eye in some sense to identify a person. To cater this need and using the observations of human psychophysics, face recognition as a field emerged. Different approaches have been tried by several groups, working world wide, to solve this problem. Many commercial products have also found their way into the market using one or the other technique. But so far no system or technique exists which has shown satisfactory results in all circumstances. A comparison of these techniques needs to be done. In this paper, we will try to do a comparative study of the performances of three algorithms - PCA, LDA and Morphological methods for face recognition. Keywords-Morphological Method, PCA, LDA, Neural Networks, Face Recognition, LVQ.
Face Recognition Using different level of Algorithms
Sushma Jaiswal
Journal of Global Research in Computer Science , 2011,
Abstract: This paper proposes the automatic face recognition method based on the face representation with five major processing modules- Filters, Face Location, Feature Location, Normalization, and Face Recognition. This precisely reflects the geometric features of the specific subject. We test our proposed algorithm database, and experimental results, show the effectiveness and competitive performance of the proposed method.
