[Root canal filling after apicoectomy, as seen on the scanning electron microscope].

The radiologically controled apicectomy shows frequently unsuccessful results. In histological examinations of the root apex area after apicectomy chronic inflammation is regularly seen even in negative radiologic findings. Examination of the most frequently used root filling material (zincoxyphosphate with guttapercha point) by scanning electron microscopy shows a porous surface and between the canal wall and the root filling material there appears regularly a deep groove as no contact is achieved. The rough surface structure, the chemical composition and the loose contact of the components in this area are considered irritative factors and reasons of failure in treatment.

Temporary restorative materials: properties and uses.

Various materials used for temporary restorations are reviewed, with reference to their chemical and physical properties. Research and standard specifications should be instituted in order to standardize and improve the many products now available to the profession. Knowledge of the materials and their properties will enable the dentist to arrive at correct selection of the material for each case, thus promoting more successful clinical procedures.

Instrumentation of finely curved canals.

The conclusion to be reached should not be that one method of enlargement is better than another in finely curved canals, or that one filling material is better than another but rather that all materials and methods have strong points and weak points which should be taken into consideration when endodontic therapy is performed. The stepback enlargement technique is probably the best technique for enlarging finely curved canals, but problems may be experienced with it also if careful procedures of instrumentation and cleansing are not followed. If these factors are kept in mind it will help us to provide the highest possible quality of endodontics.
