The Faculty as a whole has increased its publications and held a steady state of about 1 publication per staff since 1996. The staff publication ratio is comparable with top international dental schools.

Categorisation of journals for publication impact

A large scale University-level exercise was carried out in 2001 to reclassify the existing journals into 4 categories:

  • Premier (top 10%)
  • Leading (next 20%)
  • Reputable (next 25%)
  • Others (next 45%)

The purpose of this exercise is formative - to know where NUS is today based on the quality of our publications and to move towards a profile characteristic of a prestigious university where presumably the number of publications peaks in the "premium/leading" journals category and tails off in the "others" category.

The quality of publications improved over the years as staff concentrated not on quantity but the quality of publications. Reviewing the publications in the past 6 years, none was submitted to premier journals (top 10% of dental journals) in 1995. In 1996 and 1997, there were a total of 15 papers (32.6%) published in the premier category. In 2000 alone, 14 papers (48%) were published in premier journals.
