title: Biological restorations as a treatment option for primary molars with extensive coronal destruction--report of two cases.
abstract: This article reports the cases of two young children aged 4 and 5 years, in whom biological restorations using tooth fragments were placed in primary molars with severely damaged crowns due to extensive carious lesions. After radiographic and clinical evaluation, tooth fragments obtained from extracted teeth in stock were autoclaved, adjusted to the prepared cavity and bonded to the remaining tooth structure with either adhesive system (Case 1) or dual-cure resin-based cement (Case 2) over a calcium hydroxide layer and a glass ionomer cement base. Occlusal adjustment was performed and topical sodium fluoride was applied to tooth surface. Periodical clinical and radiographic controls were carried out and the restored teeth were followed up for 4 and 3 years, respectively, until exfoliation. In these two reports, the technical aspects are described and the benefits and disadvantages of biological restorations as an alternative treatment for rehabilitation of severely destroyed primary molars are discussed.
