Use of Facial Indicator for Choosing Anterior Teeth (Female Arabs and Persians Students)

Abstract

Background: The maxillary anterior teeth are important in achieving pleasing dental aesthetics. The size of the maxillary central incisors is important for they are the most prominent teeth in arch as individual is viewed from frontal position. Various methods are used to measure the size of them, including the size of the face determined from two points, zygoma and chin to estimate the width and height by using “facial indicator”. The average width of the maxillary central incisor is estimated to be one sixteenth of the face measured between the zygoma. Objectives: The purpose of this study is to investigate the accuracy of a new device called “ facial indicator “ in choosing anterior teeth in dentulous patients of two different ethnic groups, Female Arabs & Non-Arabs (Persians) by attempting to prove the existence of a direct relationship between the facial sizes and the size of the natural maxillary central incisor. Methods: Dental casts of the maxillary arches were made in this cross-sectional study from AUST university college students who met the inclusion criteria. The 90 female participants represented the Arabs and NonArabs (Persians) population main ethnics. The width and height dimensions of the maxillary central incisors were measured using digital caliper. Then Facial Indicator Device used to decide the width and height of face in an attempt to prove the existence of a direct relationship between the facial sizes and the size of the natural maxillary central incisor. Results: Comparison of the width and height of maxillary central incisor on the casts and the width and height dimensions of faces by using facial indicator, revealed that there was a significant statistical difference (p >0.05). Conclusion: A direct relationship between the facial width and the widths of the natural maxillary central incisors was found, while there is no relation between the lengths of the face with the length of the central incisors. Ethnic variation has no association with the use of facial indicator.
