Color Stability Of Conventional, 3d-Printed, And Milled Denture Teeth After Immersion In Coloring Agents: An In Vitro Study, Dany Nassif, Nancy Chemaly, Rim Bourgi, Carole Abi-Ghosn, Louis Hardan, Jihad Fakhouri

International Arab Journal of Dentistry

Objectives: This study investigates the color stability of denture teeth made from different materials when subjected to various staining solutions.

Methods: Forty-five A1 shade upper central incisors were divided into three groups: prefabricated, 3D printed, and milled denture teeth (N=45). Each group was further divided into three subgroups, with teeth immersed in coffee, wine, and artificial saliva for up to 120 days (n=5). ∆E values for color change were measured using an Optishade colorimeter.

Results: The type of teeth, type of solution, and immersion time had a significant effect on color stability (p < 0.001). Interactions between the three variables were all significant (p < 0.001). Conventional denture teeth showed slight color changes with saliva (ΔE = 1.256 by day 120), moderate changes with wine (ΔE = 2.893), and more significant changes with coffee (ΔE = 5.208). Milled denture teeth exhibited no color changes with saliva, noticeable changes with wine (ΔE = 5.359), and moderate changes with coffee (ΔE = 3.137). 3D printed denture teeth showed no color changes with saliva, but increased changes with wine (ΔE = 2.533) and highly significant changes with coffee (ΔE = 10.546). Coffee consistently caused the highest ΔE values, especially in 3D printed teeth.

Conclusions: The study …

International Arab Journal of Dentistry

Dens invaginatus, also known as dens in dente, is a dental anomaly resulting from infolding the enamel organ into the dental papilla. Dynamic Navigation Systems (DNS) like Navident, offer real-time guidance during endodontic procedures, proving especially useful in complex cases, such as calcified canals or pulp obliteration. This case report presents a 13-year-old female, who reported the chief complaint of continuous pain in the upper left front tooth region. Based on the clinical and radiographical findings, a diagnosis of pulp necrosis and chronic periapical abscess in relation to maxillary canine (23) was established with dens invaginated palatal canal ( Oehler’s …
