To provide the best possible treatment, factors such as the patient's cosmetic and functional needs as well as the cost factor should be considered. Case DesCriptionA 13-year-old boy with the chief complaint of a missing tooth in the upper front tooth region for 2 years reported to our department. The patient gave a history of fall from a bicycle 2 years ago, following which he had undergone treatment in a private dental clinic. The patient gave no significant medical or dental history. On clinical and radiographic examination, soft tissues and avulsed socket was all healed, missing maxillary right central incisor and a part of FRC was found attached to 12 and 21 (Figs 1A and B). The implant was not introDuCtionThe loss of anterior teeth regardless of age or gender has a huge impact on the quality of life. Missing teeth in a highly visual zone due to trauma, periodontal infection, or failed endodontic treatment leads to esthetic, phonetic, and functional disability.¹ The management options for replacing the anterior missing tooth include removable temporary acrylic prosthesis, resin-bonded bridges, metal and ceramic fixed partial dentures, and implant-supported prosthesis.² There have been a number of different techniques described in the literature related to restorative dentistry, for splinting teeth using adhesive composite resins, wire, metal mesh, nylon, and so forth bonded to adjacent teeth and adding a natural tooth pontic, denture tooth, or composite resin tooth pontic.³Case selection criteria for a natural tooth pontic bonded with fiber-reinforced composite (FRC) resin are the following:• Patients requiring a minimally invasive procedure.• Patient needs an immediate esthetic fix.• The extracted tooth crown and abutments must be in good condition. • Natural tooth pontic not present in a heavy stress.• Cost-effective alternative.• Periodontally compromised teeth.• Unsuccessful reimplanted tooth.
To evaluate and compare the diametral tensile strength and shear bond strength of Cention N, FujiCEM 2 with a conventional glass ionomer cement. A total of thirty samples were used for the evaluation and comparison of diametral tensile strength. Ten samples of each of the restorative material were prepared with the help of metallic moulds and stored in distilled for 24hrs, following which they were tested on the Universal Testing Machine at crosshead speed of 5.5 mm/min. A total of thirty-three premolars were used to evaluate the shear bond strength with eleven premolars in each group. The premolars were then grinded perpendicular to the long axis of the tooth, restored with the respective cements following the manufacturer's instructions and stored in distilled water at room temperature for 7-10 days, later they were subjected to thermocycling. After 24 hours, the specimens were tested in the Universal Testing Machine at a crosshead speed of 0.5 mm/min. The obtained data was statistically analyzed. There was statistical difference in diametral tensile strength values of Cention N when compared to FujiCEM 2 and Fuji IX (p value= 0.00). The shear bond strength of Cention N was significantly higher than that of FujiCEM 2 and Fuji IX (p=0.005 and p=0.008 respectively). The results of our study concluded that Cention N performed better in terms of mechanical properties than FujiCEM 2 and Fuji IX.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
