Endo-restorative management of a type II dens invaginatus in mandibular premolar associated with a large cyst

Abstract

We present the management of a case of Type II dens invaginatus in a mandibular premolar with a large invagination in the coronal third of the root on mesial aspect of the crown in proximity of cementoenamel junction significantly compromising the strength of the crown structure. We describe in detail the various measures taken to assess the internal tooth structure destruction and enhance the fracture resistance of the involved premolar. The case has a long-term follow-up of 36 months showing clinical and radiographic signs of healing. We highlight use of a simple “foil coated fiber postblocker technique” for root reinforcement in the first premolar. Successful management of teeth with dens invaginatus can be effectively done using with careful treatment planning and selection of reinforcing adhesive restorative materials.

Application of personalized templates in minimally invasive management of coronal dens invaginatus: a report of two cases

“…CDI has diverse clinical manifestations, encompassing multiple shapes and sizes [ 5 ]. The thin lining of the invagination can retain plaque and food debris, thereby increasing the risk of caries, pulp necrosis, periapical inflammation, and even odontogenic cyst formation [ 6 ]. Oehlers categorized CDI into three types based on the extent of invagination: type I (65.9%), type II (29.5%), and type III (4.6%) [ 2 ].…”
