Full-Arch Rehabilitation Of Post-Mucormycosis Edentulous Maxilla Using Quad Zygomatic Implants: A Clinical Case Report, Akansha Bansod, Sweta Kale Pisulkar, Arushi Beri, Mony Behera, Pragya Manushree, Utkarsh Umre, Michael Subal Pramanik

International Arab Journal of Dentistry

Rehabilitating the maxilla in the patient who has had surgical resection for mucormycosis poses a distinctive set of anatomical, surgical, and prosthetic challenges. The extensive maxillary bone loss after aggressive debridement often makes traditional implant-supported prosthetic options impossible. In these circumstances, zygomatic implants have proven to be a predictable, graftless solution, especially in patients with extremely atrophic maxillae. Where the bone loss is severe, the quad zygoma procedure—two implants for each zygomatic arch—is possible to support full arch rehabilitation with a fixed prosthesis. This report presents the successful rehabilitation of oral function and appearance in a patient with post-mucormycosis edentulous …

Management Of A Periapical Cyst In An 8-Year-Old Patient With Challenging Etiology: A Case Report With Three-Year Follow-Up, Nancy Nochahrly, Claire El Hachem, Josephine El Balaa, Elie Khoury, Christelle Abdel Nour, Marlene Khoury

International Arab Journal of Dentistry

The success of pulp therapy in primary teeth depends on accurate diagnosis and effective treatment. Periapical inflammation due to bacterial infection or pulpal necrosis can result in granulation tissue and may activate epithelial rests of Malassez, leading to a periapical cyst. In large cysts, especially in children, marsupialization is preferred to preserve developing teeth and minimize damage to surrounding structures. This case report describes an 8-year-old presenting with spontaneous pain in the lower right jaw. Radiographic examination revealed a round welldefined radiolucency over 1 cm around tooth #84 with root canal treatment and #85 with pulpotomy, with dental bud displacement. …

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 …
