Discordant tooth agenesis and peg-shaped in a pair of monozygotic twins: Clinical and molecular study
نویسندگان
چکیده
The present report aimed to study an uncommon case of a pair of twins that presented a discordant dental phenotype. Family investigation, clinical, radiographic examination and molecular analysis were performed in both girls. Molecular analysis confirmed the monozygosity by deoxyribonucleic acid chip technology. One twin presented tooth agenesis in left upper lateral incisor and peg-shaped on the contra lateral side while the other twin had no dental alterations. The dental casts study employed digital caliper to compare morphological dimensions and showed alteration only in peg-shaped tooth. In conclusion, this study provide support that one or more mutated gene could cause discordances in dental phenotype in these monozygotic twins.

Introduction & Objective: The study of monozygotic twins is a valuable method for distinguishing the genetic and environmental etiologic factors. The purpose of this study was comparison between occlusal indices and dental arch dimensions in monozygotic twins. Materials & Methods: This descriptive study was preformed on 40 monozygotic twins that their permanent teeth were fully erupted. The ...
متن کاملMonozygotic twins discordant for rubinstein-taybi syndrome.
A pair of male monozygotic twins discordant for Rubinstein-Taybi syndrome is reported. Monozygosity of the twins was established using blood grouping, typing of serum proteins, isozymes, HLA, and chromosomal heteromorphisms. The twins are the first twin pair discordant for the syndrome in which monozygosity has been firmly established. The pathogenesis of the syndrome is discussed in relation t...
متن کاملImpacted Primary Tooth and Tooth Agenesis: A Case Report of Monozygotic Twins
In the present report, a case of 19 year-old monozygotic twin brothers with similar tooth agenesis and impacted primary teeth is presented. Both twins (HDH, DHH) had agenesis of ten and eleven teeth (respectively), third molars excluded, consistent with oligodontia and both had four impacted primary teeth and the permanent successors of all these primary teeth were congenitally missing. The occ...
متن کاملTHE EFFECT OF GENETIC AL AND ENVIRONMENTAL FACTORS ON LIPIDS: A TWIN STUDY
To assess the relative contribution of genetic and environmental factors (particularly androgens) on circulating levels of lipid fractions, serum androgen and lipid fractions were measured in 34 pairs of female-female twins aged from 15- 45 years, some of whom were discordant for polycystic ovary syndrome (PCOS) diagnosed by ultrasound. Nineteen pairs were monozygotic twins (MZ) and 15 pai...
متن کاملMSX1 and PAX9 investigation in monozygotic twins with variable expression of tooth agenesis.
Non-syndromic agenesis of permanent teeth is one of the most common anomalies in human development, a multifactorial characteristic caused by genetic and environmental factors. We describe a pair of monozygotic twins who showed second premolar and third molar agenesis, albeit with different expressions. We studied the DNA of two genes, paired domain box gene 9 (PAX9) and muscle segment homeodom...
