Hereditary ectodermal dysplasia is an inherited disorder involving skin, hair, nails and teeth. Two main clinical forms have been described--hypohidrotic type and hidrotic type. A case of ectodermal dysplasia with absence of hypohidrosis and defective nails has been reported. The importance of early prosthetic management has been discussed.
In the past few years the importance of coronal seal following root canal therapy has been emphasised. Adhesive restorative materials have been used, considering their good bond strength and their sealing ability. In this study, the sealing ability of resin modified glass ionomer has been compared with composite resin used with fifth generation bonding agent (in vitro), using methylene blue dye penetration method. Resin modified glass ionomer showed greater leakage than composite resin, although it was not statistically significant. Further studies are needed to asses the sealing efficacy in clinical situations.
The importance of apical seal has always been stressed in endodontic therapy. Root canal sealers have been used along with gutta percha to enhance the seal. The apical sealing ability of AH26/silverfree, a modified version of AH26, a resin based sealer was compared with tubliseal, a zincoxide eugenol based sealer using methylene blue dye penetration method. AH26/silverfree showed superior sealing ability.
