Abstract
Objective: To determine the mean vertical dimension of occlusion among dentate population by using different anthropometric measurements in relation to eye. Study Design and Setting: It was a cross sectional study conducted at outpatient department of prosthodontics, Liaquat University of Medical and Health Sciences, Jamshoro from March –Sep-2019. Methodology: Five eye characteristics were measured. The distance between the outer canthus of one eye and the inner canthus of the opposite eye is measured in millimeters, outer canthus to rima oris distance, interpupillary distance, mid pupil to rima oris distance and canthus to tragus distance. Data were analyzed using SPSS Version 20. Mean and SD for age distinction between right and left pupil, rima oris and tragus. The outcome was assessed using age and gender stratification. The age and gender groups were compared using a t -test. Results: Total n=100 patients with complete dentitition were included for data collection. Mean age was 22.75±1.86 years. Mean vertical dimension of occlusion (OVD) among dentate population was 67.73±1.02 mm. The mean inter canthus distance was 63.13±2.95mm, the mean interpupillary distance was 61.21±1.67mm, rima oris to pupil was 67.46±1.53mm and eye to ear distance was 70.04±1.68mm Conclusion: The OVD index identifies the precise vertical dimensions as being present in dentate populations. This index could be used in clinical setting before using other methods to estimate vertical dimension to provide a general sense of the patient's vertical dimension.
