Effect of Commonly Consumed Beverages on Microhardness of Two Types of Composites.

Objective: The objective of the present study was to assess the influence of commonly consumed beverages on the microhardness of microhybrid and nanofilled composite resins.

Materials And Methods: Two hundred and forty cylindrical specimens were produced using circular aluminum molds of an internal diameter of 10 mm and a thickness of 2 mm, 120 samples each from microhybrid composite (Filtek Z250, 3M, ESPE, USA) and nanofilled composite (filtek Z250, 3M, ESPE, USA). They were divided into 4 subgroups of 30 specimens each.

Ainhum: A Spot Diagnosis.

Ainhum is an acquired progressive condition presenting with a constriction ring around the fifth toe. Classically, it was reported in people of African origin and has been very rarely reported in India. Ainhum when diagnosed and treated early can be prevented from progressing to mutilating deformities.

Investigations of some aspects of the spray process in a single wire arc plasma spray system using high speed camera.

A high speed camera has been used to record and analyze the evolution as well as particle behavior in a single wire arc plasma spray torch. Commercially available systems (spray watch, DPV 2000, etc.) focus onto a small area in the spray jet.

Thoracoscopic removal of impacted denture: Report of a case with review of literature.

Impacted foreign bodies in the oesophagus are common. Because of their large size, rigidity and pointed edges, dentures get frequently impacted in the oesophagus and are difficult for endoscopic retrieval. Traditional thoracotomy for retrieval of impacted foreign bodies in the thoracic oesophagus is associated with significant morbidity.

Regeneration of plantlets in Sapindus trifoiatus L.

Continuous production of healthy plantlets of Sapindus trifoliatus L. was achieved via somatic embryos from long term cultures of an embryogenic mass (EM). A highly embryogenic culture of S.
