Re-attachment of Anterior Tooth Fragment using a Self-etching Adhesive: A Case Report

Abstract

The purpose of this case report is to describe the re-attachment of an anterior tooth fragment using a selfetching adhesive. Background: Fracture of anterior teeth by trauma is a common problem in children and teenagers due to their active lifestyle. Restoration of these teeth often presents a challenge because of the large pulp in young teeth and open apical foramen depending on the age of the child. New dental adhesive materials offer an alternative solution for the treatment of some anterior tooth fractures. Report: A 17-year-old female patient presented for treatment of a fractured maxillary left central incisor. The clinical examination revealed the exposure of dentin, but there was no exposure of the pulp. The patient saved the tooth fragment making it available for re-attachment to the remaining tooth structure. Under local anesthesia and rubber dam isolation the tooth fragment was re-attached using a self-etching adhesive and a microhybrid composite. Summary: The re-attached tooth fragment was assessed clinically, radiographically, and using photographs at one, six, 12, 24, and 36 month intervals. The tooth remained vital, and there was no change in the color of the tooth at the three-year recall.

Cavity Carbon-Nanopipette Electrodes for Dopamine Detection

“…Small animal models such as Drosophila and zebrafish are easy to genetically manipulate, [1][2][3] but the small dimensions of their central nervous systems require better spatial resolution to implant the probe into a specific brain region. [4][5][6][7] In addition, measurements of neurotransmitters are being made in single synapses, which require an electrode with a nanosized tip, preferably in a disk geometry. 8 Carbon nanofiber microelectrodes fabricated on large silicon chips have been developed for neurotransmitter detection, but the large dimensions of the chip and the geometry limit the implantation.…”

Alternative Treatment Procedure in the Case of Fractured Abutment of Adhesive Bridge: A Clinical Report

“…This result is in agreement with the results of Toshihiro and Rintaro 21 who explained that the incisal fragment may regain some original color because of water absorption in the mouth. Many techniques have been proposed for reattaching the fragment to the remaining tooth such as placement of a circumferential bevel before reattaching the fragment, 4,5,11 placement of an external chamfer at the fracture line after bonding, 4,5,11 use of a V-shaped enamel notch, 4,5,11,26 placement of an internal groove, 4,5,11,23 leaving a superficial overcontour of restorative material over the fracture line, 4,5,26 when endodontic therapy is required, using the pulp chamber as an inner reinforcement 26 or using fiber posts. 1 Reis and colleagues 27 suggest that use of additional preparation (bevel, chamfer, and overcontour) is needed to enhance the resistance to fracture of the reattached fragment.…”

“…In the last three decades, many authors have proposed a valid alternative to conservative treatment of these fractures represented by the re‐bonding of the fractured fragment 4,6–9 . If a broken fragment is available, the restoration of teeth with its own fragment has been suggested as an alternative treatment 1,5,10–15 …”

Comparative Evaluation of Fracture Resistance and Microleakage of Reattached Anterior Tooth Fragment Using Two Different Flowable Composites- An in vitro Study

“…[3,4] Coronal fracture of permanent incisors represents 18-22% of all traumas to dental hard tissues; of these, 96% involve maxillary incisors (80% central incisors & 16% lateral incisors). [5][6][7][8][9] Traumatic dental injuries not only cause damage to the dentition, but also have a psychological impact on the child and his parents as well. [10] Chosack and Eildeman first described reattachment of tooth fragment after trauma to 12-year-old child.…”
