Abstract: Choosing suitable artificial teeth for partially edentulous patients and arranging these teeth in a way to look natural is difficult. An important factor in dentures construction is the mesiodistal width of anterior teeth, because a denture would not appearance natural if artificial teeth are of incorrect size. While for a successful orthodontic treatment, mesiodeistal width of teeth is important for space analysis and for establishing proper occlusion. The aim of this study is to determine the correlation between the average mesiodistal width of anterior and posterior teeth in male and female Iraqi population.40 Iraqi subjects with normal occlusion participated in this study. Mesiodistal measurement of all teeth was carried out on stone cast. Obtained data was analyzed using SPSS 15 computer software. Mean and standard deviation were calculated for each variable. Comparisons between male and female samples were made for each variable using t-test. The average mesiodistal width of maxillary central incisor for male and female samples was (8.84 0.46 and 8.58 0.45, respectively). Mesiodistal width for mandibular central incisor for male and female samples was (5.46 0.41 and 5.44 0.24, respectively). These results are well within normal value for other ethnic groups. The ratio between maxillary and mandibular anterior and posterior teeth was also calculated. Mesiodistal width of anterior teeth and posterior teeth can be used as a guideline for choosing correct artificial teeth for partially edentulous patients and it is important for a good outcome in an orthodontic treatment.
