Introduction: This study was conducted to assess the determinants factors of the dental arch forms of Yemeni adult sample. Materials and Methods: The Eucledian clustering method of analysis was utilized for determination of the dental arch form, (398) study models were constructed and evaluated to do measurements for both arches using the modified sliding caliper gauge. A total of 6 dental cast measurements were divided into three sagittal measurements and three transverse measurements were utilized, which represent the dental arch widths and lengths measurements. Results: Narrow form is the most prevalent arch form 30.8% followed by wide form 24% their prominence appearance in females and the least prevalent arch form was the mid form 9.3%, whereas flat and pointed forms being in between 18.3% and 17.6 respectively. Conclusion: Five arch forms: Narrow, wide, mid, pointed and flat were distinguished as unique forms for the maxillary and the mandibular arches. It can be observed that the measurements related to the canine, have the widest range of reading and give the impression that the relation of canines to each other and to other teeth is the strongest factor in determining the dental arch form. |
