  3. In the field of operative dentistry, esthetic restorative materials and bonding to tooth constituted major subjects of the studies. In the field of endodotics, pulp biology was prominent and canal shaping, endodontic microbiology and canal obturation were steadily reported.

  4. According to author's school, similar number of papers were published in the field of operative dentistry and endodontics in general. However, some schools showed preponderances.

  5. Most studies were done by two or more authors. Studies published by two authors were most.
