Regional odontodysplasia

Regional odontodysplasia is a rare, severe, and nonhereditary developmental disorder in tooth formation and involves epithelial and mesenchymal-derived dental tissue. On radiographs, affected teeth have an abnormal morphology, a hypoplastic crown, and only a faint outline of hard tissue, a condition termed “ghost teeth.” We report clinical and radiographic findings from two children with regional odontodysplasia. Using computed tomography (CT), we calculated attenuation coefficients (i.e., Hounsfield units) for affected teeth and assessed the condition of dental follicles. To measure density, regions of interest were delimited and CT values were calculated. In our two patients, the CT values for enamel were lower in affected teeth than in sound teeth, while CT values for dentin were similar for affected and sound teeth. The average CT value for dental follicles in affected teeth was about 65 to 120, which suggests that dense fibrous connective tissues or hard tissue-like structures might be present in dental follicles. Analysis of CT values may be quite useful in the diagnosis and treatment of regional odontodysplasia.

Background. Odontodysplasia is an uncommon condition. It can be localised or generalised, isolated or part of a syndrome.Case Report. We first report the case of an 8.5-year-old boy who presented with abnormally shaped teeth and multiple intraoral abscesses. Findings of clinical and radiographic examinations were consistent with those of generalised odontodysplasia. A 2-step, conservative treatment plan was executed with a 10-year followup. Step 1 was root canal treatment of nonvital teeth. Step 2 was crowning without preparation of new vital, erupted, and malformed teeth. The second case is that of a 12-year-old girl who presented with lack of teeth in the upper-left quadrant. The impacted teeth were exposed surgically, and fixed restoration was performed for temporary aesthetic improvement.Conclusion. Instead of tooth extraction, an approach previously used in similar cases, conservative management is feasible and offers better prosthetic treatment options for the future.
