Many studies in dental research are based on repeated measurements of several continuous variables. Statistical analyses of such data require advanced methods to explore the complexity of information within the data. Currently, the most frequently adopted approach is to undertake multiple univariate tests. ⋯ The aim of this article was to present a non-technical introduction to latent growth curve modelling for dental researchers. The emphasis was on conceptual understanding, rather than mathematical rigor, so path diagrams were used for visual presentations of various statistical models. When properly applied, latent growth curve modelling has great potential to give new directions for future longitudinal dental research.
