Abstract

Mesiodens is the most common form of supernumerary teeth, usually located in maxilla, in the region of medial line. The overall prevalence of mesiodens in primary, mixed and young permanent dentition varies between 0.09 and 2.05%. However, occurrence of double mesiodentes in patient without any associated systemic conditions or syndromes is a rare phenomenon. This paper presents a report of nonsyndromic double mesiodentes in 3.5-year-old girl with positive family history of supernumerary teeth. Both of mesiodentes had conical shape. One of supernumerary tooth was partially erupted and caused mesial displacement of deciduous maxillary right incisor, root resorption of that tooth found on intraoral radiograph, as well as rotation of the germ of permanent incisor. While the other was impacted and inverted. Mesiodentes were surgically removed under general anaesthesia. The healing was uneventful. As the mesiodens is a single or multiple anomaly that a dental practitioner may come across, the paper discusses signs, complications and management of mesiodentes. It also emphasizes the importance of early detection and adequate management of single or double mesiodentes to minimize the future dental complication or malocclusion caused by this anomaly.
