ABSTRACT
Introduction: Mesiodens is a common supernumerary tooth occurring in anterior region of maxilla. Its occurrence is more in permanent dentition than the primary dentition. Presence of mesiodens is associated with various complications, cystic changes being less common complication of mesiodens itself. Objective: The aim of the present article is to report an atypical mesiodens with cystic changes causing complication in adjacent structures. Case report: Hereby we report a case of dentigerous cyst associated with atypical mesiodens which was impacted, inverted and had dilaceration in the crown. Surgical removal of cystic lesion along with the mesiodens was carried out. Conclusion: Supernumerary tooth associated with dentigerous cyst may result in considerable bone destruction along with other complications. Dentist should be aware of complications associated with supernumerary structures.
ABSTRACT
Impaction with a severely dilacerated root is seldom reported, especially in the maxillary incisor. It is probably because of the high clinical difficulty associated with bringing the dilacerated tooth into proper position, and the high chance of failure due to ankylosis, external root resorption, and root exposure after orthodontic traction. Even the successful cases may need periodontal surgery to improve the unesthetic gingival shape. However, it has previously been reported that an impacted maxillary central incisor was successfully treated by proper crown exposure and orthodontic traction. This article presents a case of an invertedly impacted maxillary right central incisor with a developing dilacerated root, which was aligned into proper position after orthodontic traction composed of two stages of a closed eruption technique.
