Evaluation of the Bond Strength of Universal Tray Adhesives on Silicone Impression Materials Using an Acrylic Tray.

Aim: To evaluate the bond strength of two commercially available universal tray adhesives on polyvinylsiloxane addition silicone and condensation silicone impression materials to an autopolymerizing polymethyl methacrylate acrylic tray material.

Materials And Methods: Sixty flat square specimens were fabricated from autopolymerizing polymethyl methacrylate tray material to which an eye hook was incorporated to serve as the point of attachment to a universal testing machine. A polyvinyl chloride (PVC) pipe of 15 mm diameter and 25 mm long was used to house the impression material, and a metal rod was inserted into two centered holes to provide retention that serves as the second point of attachment to the universal testing machine.

Nine years' review on preseptal and orbital cellulitis and emergence of community-acquired methicillin-resistant Staphylococus aureus in a tertiary hospital in India.

Context: Preseptal cellulitis is the commonest orbital disease which frequently needs to be differentiated from orbital cellulitis. Prompt diagnosis and treatment with appropriate antibiotics can prevent vision loss and life-threatening complications of orbital cellulitis.

Aims: To describe the clinical profile of cases with preseptal and orbital cellulitis admitted to a tertiary care hospital during a period of nine years.
