To enable investigation of palatal changes in infants who are prematurely born, it is necessary to first establish a reliable method of measurement of these tiny edentulous palates. This study compared the Olivetti-Inspector machine, Vernier calipers, and stereophotogrammetry for this purpose. Measurements were taken of 12 palatal casts of four infants at prescribed time intervals during the neonatal period. In each of the three methods, measurements were recorded as variables generated in the X and Z axes of the Cartesian scale in relation to three specified points along the Y axis. The results revealed that all methods were comparable, but the Vernier calipers differed significantly from the other two methods in height measurements, (p < 0.001). It was also found that both the Olivetti-Inspector machine and the Vernier calipers consistently underestimated the width, compared with Olivetti-Inspector machine, (p < 0.05). Stereophotogrammetry was found to be the most consistent method of measuring the configuration of preterm infant palates.
