Abstract

---

Introduction: Genes play an important role in dental morphology, which is important in detecting the kinship between people and their identity. The study of teeth is an interesting topic which inspires a continuous production of books, especially in teeth morphology. Many studies supported the gene expression theory in dental role, which showed families and groups with same dental features and tooth morphology these variations in people is under the genetic control, but on the other hand dental anomalies and abnormalities is also a co-factor with genes. Materials and methods: This is an observational study, which focused on parents and their children’s similarity in tooth morphology. An alginate impression for the upper and lower arch was taken for both parent and child. This was followed by pouring the cast and recording the Ramfjord teeth measurements including height and width. 30 families, 2 persons from each family (one parent and one child) were included in the study. Results: The study participants were also divided on the basis of the parents' marriage statuses and it was noted that 45% had married within their family, whereas 55% married outside their family. The most common type of shape among maxilla and mandible was found to be ovoid. However, the least common was Vshape. A total of eight parent/child pairs exhibited similar shaped jaws. Conclusion: No significant relation was discovered among the parents who got married within or outside families as far as similarity in size and shape of arch was concerned.

Keywords: Tooth morphology, Genetics, Malocclusion, Arch shape, Roles of genes.
