Abstract

Cancer is increasingly recognised as an important public health problem worldwide. Of the 5.9 million cases each year globally, three million come from developing countries. Circumstantial evidence in man suggests that immunity is important in host resistance aganist antigenic malignant disease and that any breakdown of the normal mechanism facilitates the development of malignant tumors.

Abstract

With the evolution of web technology, there is a huge amount of data present in the web for the internet users. These users not only use the available resources in the web, but also give their feedback, thus generating additional useful information. Due to overwhelming amount of user's opinions, views, feedback and suggestions available through the web resources, it's very much essential to explore, analyze and organize their views for better decision making. Opinion Mining or Sentiment Analysis is a Natural Language Processing and Information Extraction task that identifies the user's views or opinions explained in the form of positive, negative or neutral comments and quotes underlying the text. Text categorization generally classifies the documents by topic. This survey gives an overview of the efficient techniques, recent advancements and the future research directions in the field of Sentiment Analysis.

Abstract

Background: Wettability of impression materials is essential to obtain a void-free cast. The purpose of this study was to evaluate the wettability of the impression materials immediately after setting and also to determine the change in wettability after 24 hours.

Materials and Method: Four impression materials were selected among which two were hydrocolloids and two were elastomers. Fifteen samples of each were experimentally tested immediately and 24 hours after sample preparation. Data obtained were subjected to t-test and analysis of variance for statistical comparisons at a 5% level of significance.

Results: The contact angle values were recorded immediately and 24 hours after setting. Lesser the contact angle value more the wettability of the impression material. The changes in wettability with respect to time were statistically analysed and it showed a statistically significant difference between the materials both immediately and after 24 hours.

Conclusion: Within the limitations of the study, Elastomers showed better wettability when compared to the hydrocolloids at both time interval and they have negligible time dependant change. Newly introduced cream alginate showed better wettability at both time intervals equivalent to the elastomers and can be considered for usage.

Abstract

Impression materials are used to record intraoral structures for the fabrication of definitive restorations. Accurate impressions are necessary for construction of any dental prosthesis. The relationship between static and mobile oral structures must be reproduced accurately for an optimum cast. Making a cast in gypsum materials from an impression of dental anatomy aids dentists in designing and constructing removable and fixed prostheses. The accuracy of these final restorations depends greatly on the impression materials and techniques. Accurate impressions depend on identifying the applications that do or do not fit each material’s characteristics. Materials used without adequate knowledge of their characteristics can impair a successful outcome. Often, the choice of impression materials depends on the subjective choice of the operator based on personal preferences and past experience with particular materials.

Abstract

Multiple missing teeth situation always claim careful attention and meticulous treatment planning. It becomes more challenging when unilateral or bilateral distal extension situation exists. Successful treatment can be done with some contemporary and conventional treatment planning. This clinical report describes about the treatment planned for a 35 years old patient with a partially edentulous upper and lower jaw. The prime consideration was given to aesthetics and masticatory function.
