From Molars To Bronchus; The Tale Of An Aspirated Dental Instrument, Yisroel Grabie, Sudeep Acharya, Fasih Sami Siddiqui, Gabriel A. Chavez Reyna, Michel Chalhoub

HCA Healthcare Journal of Medicine

Background

Aspiration of dental instruments is a rare event that carries potentially serious complications when it occurs, especially in older patients, where protective reflexes are diminished. Clinical management may be difficult because of the risk of granulation tissue and different retrieval strategies according to the object’s characteristics. In this report, we describe the case of an 84-year-old man who aspirated a dental bur during a routine dental procedure, necessitating immediate intervention. Timely and precise management was essential to avert severe complications.

Case Presentation

During a routine dental procedure, an 84-year-old man aspirated a bud-shaped cross-cut carbide dental bur. Despite initial …

Evaluation Of Dentistry Students' Perceptions And Attitudes Towards Artificial Intelligence In Kazakhstan, Yasin Yasa, Kubeisin Altynbekov, Nazgul Onaibekova

Journal of Dentistry Indonesia

Objective: Artificial intelligence’s (AI) potential to analyze medical data and improve patient outcomes is driving its rapid integration into healthcare systems. This study addresses the knowledge gap regarding Kazakhstani dental students’ attitudes toward AI in dentistry. Methods: A survey with 213 participants assessed dental students’ views on AI in dentistry at two Kazakhstani universities. A self-administered questionnaire (22 items) via Google Forms was used to gather data on demographics, baseline knowledge (information sources, understanding of AI principles, and familiarity with dental AI applications), and attitudes/perceptions. Frequency analyses and chi-square tests (p < 0.05) explored the responses. Results: The survey included 213 dental students (mean …

Synthesis And Partial Characterization Of Chitosan Phosphorylation From Marine Cuttlefish Sepia Aculeata (Orbingy, 1848) And Its Antimicrobial Potentials Against Oral Pathogens, Yathin Reddy Putta, Annathai Pitchai, Pasiyappazham Ramasamy

Journal of Dentistry Indonesia

Objectives: This study investigated the synthesis and partial characterization of phosphorylated chitosan extracted from the cuttlebone of Sepia aculeata (Orbingy, 1848) and evaluated its antimicrobial potential against oral pathogens. Methods: The synthesis of phosphorylated chitosan from Sepia aculeata cuttlebone involved several steps: cleaning, deproteinization, demineralization to extract chitin, deacetylation to produce chitosan, and phosphorylation to introduce phosphate groups. Phosphorylation enhances the properties of chitosan, making it a promising candidate for oral health applications. Phosphorylated chitosan was purified and characterized using Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD), and Scanning Electron Microscopy (SEM) to confirm structural changes. This process enhances …

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 …
