A digital approach to photographing and measuring cleft lip and palate dental study casts

This paper discusses whether a digital photographic technique can be used to produce a measurably accurate image of a dental cast arch, in order to assist the outcome assessments of cleft lip and palate surgery. It describes the measurement techniques, and discusses the factors affecting reproducibility. The results indicate that measurements which were taken from a digital image, using an on-screen measuring tool, correlated significantly with measurements taken manually from a plaster dental cast arch.
