The relationship between research topics and academic prestige of journals is of relevance to assess venues for current research as well as trending areas of new research. This is of special relevance for those developing a research agenda or with defined productivity outcome expectations. This manuscript extracts prevalent topics using titles and abstracts from more than 10,000 manuscripts, constituting all published research in International Scientific Indexing (ISI) journals within the oral health specialties of oral surgery, orthodontics, and periodontics during 2018. Journals are clustered across four quartile categories according to their impact factors. The novelty of our work includes (a) an examination of a neglected unit of analysis (bigram) in oral health sciences which is of higher relevance than single-word topic definitions and (b) the use of an efficient Bayesian hierarchical approach to extract and rank topics across quartiles with information borrowing. Some topics persisted across quartile groups, while others show higher prevalence in specific quartiles, indicating that topics may find some journal quartiles a more appropriate venue for publication. All quartile groups show a prevalence of empirical research. The approach described in this manuscript offers the possibility to adjust/generate research agendas based on research topic prevalence and dynamics. This methodology is relevant for researchers looking to define their research agendas with potential outcomes aligned with the expectations of quantity and quartile set by their home institutions. It also serves researchers to assess most likely quartiles for publication of their work.
