The study of multimodality in discourse reveals the way writers articulate their intended meanings and intentions. Systemic functional analyses of oral biology discourse have been limited to few studies; yet, no published study has investigated multimodal textual features. This qualitative study explored and analyzed the multimodal textual features in undergraduate dentistry texts. The systemic functional multimodal discourse analysis (SF-MDA) is framed by Halliday’s (Halliday, M. A. K. 2014. Introduction to Functional Grammar. Revised by Christian M. I. M. Matthiessen. 4th ed. London/New York: Taylor and Francis) linguistic tools for the analysis of Theme and Kress and van Leeuwen’s (Kress, Gunther, and Theo van Leeuwen. 2006. Reading Images: The Grammar of Visual Design. London: Routledge) framework for the analysis of visual designs. Oral biology discourse intertwines two thematic progression patterns: constant and linear. Although a split-rheme pattern was minimally employed, disciplinary-specific functions of this pattern emerged. The SF-MDA of the composition of information in oral biology pictures extends Kress and van Leeuwen’s functional interpretations of the meaning-making resources of visual artifacts. Finally, the pedagogical implications for science tutors and for undergraduate nonnative science students are presented.
