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 …

Endodontic Management Of Dens Invaginatus Using Dynamic Navigation System In Pediatric Patient: A Case Report, Ayesha Fathima, Sahana Selvaganesh, Ganesh Jeevanandan, Pradeep Solete, Prabahdevi Maganur, Ather Syed Ahmed, Satish Vishwanathaiah

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 …

Objective: This case report provides two cases with varied approaches for the management of complicated and uncomplicated crown fractures using reattachment procedures. Case report: During the clinical examination, the first case described the management of an uncomplicated fracture using the …

Resin-Build-Up As A Direct Monoblock Concept For Root Canal Dentin, Core, And Crown Restoration On Anterior Endodontically Treated Tooth, Citra Kusumasari, Takashi Hatayama, Junji Tagami, Yasushi Shimada Prof.

Journal of Dentistry Indonesia

The long-term clinical performance of restoration in endodontically treated teeth (ETT) is an essential yet complicated strategy to achieve it. A resin-build-up tooth with higher elastic moduli is a minimally invasive strategy to decrease the risk of catastrophic root fracture. Additionally, intracanal resin composite anchorage simplifies the restorative procedure and increases the bonding. Objective: This case report describes a resin-build-up tooth restoration using the direct monoblock concept to replace a failed metal post and core and porcelain fused to metal (PFM) crown on the maxillary right central incisor. Case report: A 50-year-old man attended a dental university hospital …

Minimally Invasive Treatment Of Molar Incisor Hypomineralization Without Using Burs: Experiences Via A Case Series In Vietnam, Võ Truong Nhu Ngoc, Nguyen Phương Huyen, Le Khả Anh, Phan Thi Thu Hang, Hoang Kim Loan, Ta Thành Dong

Journal of Dentistry Indonesia

Mild form of molar-incisor hypomineralization (MIH) on anterior teeth are posing great challenges to dental practitioners as it can have a huge aesthetic impact. In terms of deep MIH-related lesion below the healthy enamel, highly invasive methods for approaching the lesion body and removing the entire hypomineralized enamel using burs could lead to failures including aesthetic problems and even further tooth structure damage to the affected teeth. Case report: To resolve t his issue, we have proposed a modified resin infiltration technique based on the minimally invasive philosophy. In this study, we would like to report three specific cases …
