A number of ways have been investigated for administration of antibacterial agents in dealing of plaque-initiated periodontal disease. These include prolonged release intrapocket devices which are inserted at diseased sites. Intrapocket drug delivery system was designed which contain Doxycycline Hyclate an antibacterial agent. The formulations were so developed with an aim to reduce the dose of...

In this study, Al/Gr composites with 5,10,15,20 weight percent of graphite were produced by in-situ powder metallurgy method. The produced powder mixtures were consolidated and sintered at optimum conditions. The resultant composites were solution treated at 495?C and aged at 170?C. The influence of graphite content on the bending strength of composites was studied. The distribution of graphite...
