The dentine-pulp complex is normally protected from the microbial invasion by the intact enamel and cementum. The ingress of invading bacteria occurs when there is a break in the integrity of the overlying enamel and dentine by caries, trauma, and contamination of the pulp during dental treatment (including root canal treatment), seepage of saliva through cracks or inadequate coronal restorations. The bacteria of the carious process advances ahead when the infecting pathogen enters through caries. When there is trauma without pulp exposure, the access of the bacteria is through the dentinal tubules. With the establishment of infection, the microbial flora changes from an initially predominant facultative Gram positive flora to a completely anaerobic Gram negative bacteria when the canals have been infected for 3 months or more

ADVANCE DIAGNOSTIC AIDS IN SCREENING OF ORAL CANCER
Oral cancer is the sixth most common malignancy with almost 500000 new cases reported worldwide annually. The diagnosis of oral cancer at an early stage has a good prognosis as the survival rate is high (around 80%). However, the majority of oral cancer cases are diagnosed at a later stage with a considerably poor 5-year survival rate of 50% according to World Health Organization statistics. Thus, an effective management strategy for oral cancer will depend on its early identification and intervention which would pave the way for superior prognosi
Fracture Behavior of Biological Materials and Interfaces
Fracture Behavior of Inhomogeneous Biological Materials and Interfaces
Biological materials like bone, nacre, human tooth layers are inhomogeneous materials made up of soft collagen, and hard, hydroxyapatite (HAP) mineral arranged in such a fashion so that these materials have higher strength and toughness, the measure of crack resisting behavior in materials, at the same time, which is exclusive in nature for different class of materials available for different application areas. The interfaces in these biological materials are designed in such a fashion so that the load transfer between the constituents takes place so smoothly, therefore, become a region of strength, not susceptible to failure like in other man-made materials and composites. It is important to understand these aspects of biological materials so that they can be mimicked to the novel materials to satisfy the growing need of different industries.
This work is focused on studying different layers of human tooth, and its interface for crack initiation and growth, the crack arresting behavior of the interface layer of the outer cover of human tooth, the enamel, and the inner, dentine, called dentine enamel junction. These works are done by developing a numerical model using the commercial finite element analysis tool, ABAQUS. The crack growth pattern of the enamel and the dentine has also been investigated. The role of porosity and permeability on the energy release rate which is the measure of fracture toughness has also been investigated. The key features of the book are:
- Study on the role of shear modulus of the defect and the matrix material in which the defect is embedded on the energy release rate.
- The role of small coating layer between the outer matrix and the inner layer on the fracture behavior, especially the stress concentrations in these different layers due to change in the elastic modulus.
- The crack growth pattern in human enamel, the outer tooth layer.
- The crack arresting phenomena of the interfacial, dentine enamel junction (DEJ).
- The role of porosity and permeability on the energy release rate in the inner layer of human tooth, dentine.

मानवाधिकार का आधार मानव के सर्वांगीण विकास के लिए साधन
उपलब्ध कराना है। वस्तुतः मानवाधिकार की नींव ऐसे विचारों से
निर्मित है, जिनके अनुसार सभी व्यक्तियों को प्रकृति ने समान रूप से
समान अधिकार प्रदान किए हैं। मानवाधिकार प्रत्येक व्यक्ति को जन्म
के साथ ही प्राप्त हो जाते हंै, और मृत्युपर्यन्त तक संरक्षित रहते हैं।
मानवाधिकारो ं की प्राप्ति की एकमात्र अर्हता व्यक्ति का मानव होना है
अर्थात् सम्पूर्ण मानवों को यह अधिकार स्वतः ही प्राप्त हो जाते है।
मानवाधिकार गुण-धर्म, प्रतिभा, बुद्धि आदि ऐसे तत्व हैं, जिनसे वंचित
मानव की तुलना पशु से ही की जा सकती है।
Sabjiyo ki Adhunik kheti (Hindi)
भारत एक कृषि प्रधान देश है जहाँ की लगभग 70 प्रतिषत जनता कृषि कार्य करती है। बढ़ती हुई जनसंख्या तथा भूमि की उत्पादन दर कम होने के कारण कभी-कभी भोजन की पूर्ति की समस्या गंभीर रूप धारण कर लेती है। भारत में खाद्य पदार्थों का कम उत्पादन होने का दूसरा कारण यह भी है कि यहाँ अधिकतर लोगों की काम करने की क्षमता कम है क्योंकि वे असंतुलित एवं कम पोषण आहार के ऊपर निर्भर रहते हैं अतः स्वास्थय ठीक न रहने से उनकी कार्य करने की क्षमता भी कम होती है। इस प्रकार स्वस्थ्य जीवन के लिए सन्तुलित एवं पोषक आहार जरूरी है।
STEM CELLS IN DENTISTRY
“And now science has presented us with a hope called stem cell research, which may provide our scientists with many answers that have for so long been beyond our grasp. I don't see how we can turn our backs on this. There are so many diseases that can be cured or at least helped. We've lost so much time already. I can't bear to lose any more.”
The Postcolonial Experience
I would like to investigate the genre of postcolonial
science fiction in the context of capitalist globalization.
Science fiction is predominantly a western genre, and it is
very difficult to find postcolonial/third world works in this
genre. I will first try and establish the validity of this genre
and how it relates to globalization and imperialism. Some
of the key questions I will examine are: How postcolonial
science fiction relates to late capitalism and globalization?
What is the role of technoscapes in the genesis of
postcolonial science fiction genre and how in turn
postcolonial science fiction represents technoscapes?
