ABSTRACT
Background: the places in which the anterior teeth appear to touch have been referred to as the Connector Zone [Space].There is the distinction between a connector zone and contact point. Connector zone is one the interposing factor if smile design which may vary with moving away from midline in anterior teeth, so the variation of this space should be very well noticed in order to reconstruct a good smile. Because of absence of this kind of a research in Iran and also presence of some incomplete article related to this topic, we decided to assess [ analyze ] the position of connector zone in anterior teeth of both female and male scholars and referred patients with different ages at Tehran Islamic Azad University, school of dentistry in 1384
Materials and Methods: this was a descriptive study in which 320 female and male samples divided in to four 10-year old groups[20-30 year-old,30-40 year-old,40-50 year-old, above50 year- old]. All of the interfering variables were omitted. Different stages of this study were clinical examination, completion of informative form, providing two photographs from frontal and lateral view of anterior teeth using digital camera and analyzing images in P.C. Connector zone rate between maxillary central incisors, between maxillary central and lateral incisors, and also between maxillary lateral incisors canine were finally measured considering 100 percent of the maxillary central incisors length and this results ere obtained which presented in tables and charts
Results: this study showed that the rate of C.Z. among maxillary anterior teeth decrease with moving away from midline. It has been also defined that sexuality is not an influencing factor in this issue. Rate of C.Z between maxillary central and lateral incisors and also between maxillary lateral incisors canine will increase with aging while it will not change noticeably between maxillary central incisors with aging
Conclusions: these results may empower dentists a criterion which will help them to reconstruct a proper smile line regarding their patient age
