This study includes comparatively evaluating and drawing general conclusion about the best advisable taper and cement for maximal retention. Eighty extracted human maxillary premolar teeth with sound surfaces were selected using dial vernier caliper. Selected teeth were randomly divided into five different taper groups (0°, 3°, 6°, 9° and 12°). The crown(More)
The efficient citral hydrogenation was achieved in aqueous media using Pd/CMS and alkali additives like K 2 CO 3. The alkali concentrations, reaction temperature and the Pd metal content were optimized to enhance the citral hydrogenation under aqueous media. In the absence of alkali, ci-tral hydrogenation was low and addition of alkali promoted to ~92%(More)
