Objective:
Pit and fissure sealants have been used for many decades to prevent the initiation of caries on susceptible tooth surfaces. The purpose of this study was to analyze the peer-reviewed published scientific literature on pit and fissure sealants over the last 50 years.
Materials And Methods:
On the PubMed database, all publications on pit and fissure sealants from 1962-2011 were extracted using the search phrase [(pit OR fissure) AND (sealant OR sealants OR adhesive)]. Details of all retrievals were individually entered into SPSS for analysis.
Results:
A total of 2829 publications were found. The mean number of authors was 2.73 ± 1.90 (range = 1-23). Although single-authorship was the modal group with 32.1%, it had a sustained decrease from 75.0% for 1962-1971 to 17.6% for 2002-2011. On the contrary, publications with three or more authors increased from 8.3% to 47.3% during the same period. Human studies accounted for 88.6% and clinical trial was 11.9%, followed by reviews at 10.2% and randomized controlled trials at 6.9%. English was the language of reporting for 82.0% of the studies.
Conclusion:
It is anticipated that future research on pit and fissure sealants will focus on newer and more effective materials.
