This study reflects willingness of dental students to adopt digital revolution in dental education which in turn may present an opportunity for educators and policy makers to modify educational methods and thereby advance student's current learning approaches.
Purpose: To study and compare the sagittal condylar angles set on a Hanau articulator using intra-oral protrusive records to angles found using a panoramic radiographic image in male and female dentulous patients. Materials and Methods: A total of 20 subjects (10 male and 10 female) Aged between 21 to 30 years, free of signs and symptoms of temporomandibular joint disorders and with intact dentition were selected. Impressions were made using irreversible hydrocolloid and all dental stone casts (type-III), were mounted on a Hanau articulator using a spring bow type of face bow. For all patients, the protrusive records were made with polyether bite registration paste when the mandible was moved forward by approximately 4-6 mm, using compound jig. All procedures for

Gums and resins occupy a prime place among Non-Wood Forest Produce (NWFP/NTFP) and are known to mankind since time immemorial. Gums are metabolic by-products of plant tissues either in normal course or often as a result of disease or injury to the bark or wood of certain plants and it cannot be reenter with plant system. Gum Karaya (Sterculia urens Roxb.) is a dry deciduous tree belonging to the family Sterculiaceae distributed throughout India and Chhattisgarh. The impact of gum enhance ethephon was found significantly superior, regarding the production of biopolymers. The biological (anatomical), studies were done via taking the sample of soft (sapwood) after injecting the gum enhancer ethephon at different time intervals. It can observed that the application of ethephon enhance the process of gummosis due to formation of gum duct. The gum duct formation was observed in histological analysis of bark section within 2 hrs of ethephon treatment in gum Karaya. The histological changes indicated that the gum ducts lysigenously are present in the pith and cortex of the young stem of Sterculia urens but absent in the xylem. The commercial tapping of Karaya is done by blazing, peeling, or by making deep cuts at the base of the bole using an axe or a cycle. These methods often lead to the death of the tapped trees. On account of crude tapping methods and over exploitation the population of karaya trees has markedly declined. The harvesting method currently used are traditional and injurious due to which often obtained inferior quality of products. Hence, the study was undertaken in ICAR Network Project to develop the scientific tapping technique for sustainable harvesting in major gum producing tree of Chhattisgarh state to enhance the livelihood of the rural areas as well as to protect the plant and generate the revenue of the government. The chemical tapping method using ethephon and IAA injected by battery operated drill machine. However, temperature and relative humidity also play significant role in gum exudation. The ethephon @ 3.9% in 4 ml in two consecutive doses in 45-60 days intervals at high temperature in month of April to June was found significantly effective for maximum gum production during both the year 2015 and 2016. The physiochemical properties of exudated gum were investigated and gum was found to be mild acidic, least soluble in cold water but absorb water and swell, soluble in hot water but insoluble in organic solvent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
