Abstract
Dimension of occlusion (VDO) indicates face length. Increased VDO may cause pain in muscles and joint, difficulty in phonation and swallowing, sensitivity in tooth because of traumatogenic forces, abnormal wearing of teeth, tired facial expression an, and elongated face. To determine the vertical dimension of occlusion by eye-Rima Oris distance and its relation to measurements of nasal to gnathion and subnasal to menton.Cross Sectional Study was done.The Department of Prosthodontics, Institute of Dentistry, LUMHS, Jamshoro. From April 2018-February 2019.Total 115 were enrolled in to the study. Dots were placed on nose tip (N) and chin tip (Gn) and observation were recorded. The gap between Me and Sn was also noted. Tounge blade was used for achieving parallelism between under chin and nasal septum. Distance from outer eye to mouth corner was measure to record outcomes variable (eye-RO). Relationship was determined using Pearson correlation. Statistical significance was considered for p≤0.05. Mean Nasion-gnathion, subnasal-menton and Eye-rimaoris was 66.36±2.58, 53.98±3.43 and 64.39±3.66 respectively. The results show positive and negligible correlation between Eye-rimaoris and Nasion-gnathion. While low positive correlation was found for as Eye-rimaoris with subnasal-menton. The results also showed significant mean difference of Eye-rimaoris with Nasion-gnathion and Eye-rimaoris with subnasal-menton..Eye-Rima Oris distance is a consistent approach for prediction of the Vertical Dimension of Occlusion.
