A CBCT Evaluation and Histological Analysis of a Human Immature Permanent Tooth After Revascularization/Revitalization Procedure.
Objectives: To radiologically and histologically evaluate the outcome of a revascularization/revitalization procedure carried out on human immature permanent premolar with apical periodontitis.
Methods: A Immature Mandibular left second premolar with symptomatic apical periodontitis of a thirteen year old boy was treated with revascularization/revitalization procedure after elimination of the root canal infection. After a 3 year successful follow up the tooth was extracted due to orthodontic reasons.
Based on the post-operative and a 3 year follow up Cone Beam Computed Tomography (CBCT) scan, a radiographic quantitative evaluation was done of the outcome of the revascularization procedure using specialized DICOM software. Post extraction the tooth was processed for histological and immunohistochemical examination.
Results: The CBCT scan evaluation showed increase in dentinal wall thickness, decrease in volume of pulp space and reduction in size of the periapical lesion post revascularization procedure. The histological examination showed mineralized tissue similar to cementoid /osteoid tissue and uninflamed fibrous connective tissue.
Conclusions: Based on the CBCT evaluation and histological findings in the present case it can be said that regeneration of pulp like tissue is possible after a revascularization/revitalization procedure.
