  • Title: Mesiodens as a risk factor in treatment of trauma cases.
    Author: Alaçam A, Bani M.
    Journal: Dent Traumatol; 2009 Apr; 25(2):e25-31. PubMed ID: 19290890.
    Abstract:
    The presence of mesiodens often results in complications including retention of primary teeth and delayed eruption of permanent teeth, closure of eruption path, rotations, retention, root resorption, pulp necrosis, and diastema as well as nasal eruption and formation of dentigerous and primordial cysts. Less common complications involving the permanent incisors include dilaceration of the developing roots and loss of tooth vitality. Therefore, early diagnosis of mesiodens has particular importance in terms of preventing such complications. However, with respect to surgical removal of mesiodens, ideal timing of intervention - immediate or delayed intervention - remains to be a highly controversial issue. While predisposing factors of dental trauma such as open bite, increasing overjet with protrusion of upper incisors, and insufficient lip closure have been well documented in the literature, there is limited evidence indicating mesiodens as a risk factor in trauma. In this report of two cases, it is aimed to emphasize mesiodens as a risk factor in the treatment of dental trauma besides its effect on prognosis.
