The O'Leary‐Rudd periodontometry system was modified to facilitate longitudinal studies of horizontal tooth mobility. Repeated measurements of the horizontal tooth mobility of tooth #27 and tooth #28 were accomplished in six patients to determine the accuracy and experimental error of the modified system. The mobility value of each tooth in all six patients was within the previously reported physiologic range of mobility values. The reproducibility or tolerance of the modified system was evaluated by calculating the coefficient of variation of the mobility measurements obtained from the repeated trials. The average coefficient of variation of the measurements within a patient was 11%. The average coefficient of variation of the measurements between the six patients was 10 %.
