A novel stable biomimetic adhesive coating for functionalization of orthodontic brackets against bacterial colonization and white spot lesions.
BMC Oral Health
January 2025
Oral Technology, University Hospital Bonn, 53111, Bonn, Germany.
Background: This study aimed to evaluate the efficacy of polydopamine (PDA) functionalization on orthodontic brackets in inhibiting biofilm formation and promoting surface bioactivity to buffer the acidity of caries-causing bacteria around orthodontic brackets and prevent demineralization. The stability of the coating in artificial saliva (AS) and distilled water was evaluated, along with its effect on pH changes in simulated body fluid (SBF) and distilled water.
Methods: Maxillary incisor orthodontic brackets underwent PDA functionalization using a dopamine hydrochloride solution following a specific protocol.
Influence of different print orientations on properties and behavior of additively manufactured resin dental devices: A systematic review and meta-analysis.

Associate Professor, Department of Clinical Science, College of Dentistry, Ajman University, Ajman City, United Arab Emirates.
Statement Of Problem: Different factors affect 3-dimensionally (3D) printed resin products. However, evidence on the effect of the print orientation on resin dental devices is lacking.
Purpose: The purpose of this systematic review and meta-analysis was to assess the impact of print orientation on the properties and accuracy of 3D printed implant surgical guides, occlusal devices, clear orthodontic retainers, and aligners.
LIPUS activated piezoelectric pPLLA/SrSiO composite scaffold promotes osteochondral regeneration through P2RX1 mediated Ca signaling pathway.
Biomaterials
January 2025
Department of Orthodontics, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai Jiao Tong University, 500 Quxi Road, Shanghai, 200011, China. Electronic address:
Addressing the concurrent repair of cartilage and subchondral bone presents a significant challenge yet is crucial for the effective treatment of severe joint injuries. This study introduces a novel biodegradable composite scaffold, integrating piezoelectric poly-l-lactic acid (pPLLA) with strontium-enriched silicate bioceramic (SrSiO). This innovative scaffold continually releases bioactive Sr and SiO ions while generating an electrical charge under low-intensity pulsed ultrasound (LIPUS) stimulation, a clinically recognized method.

J Esthet Restor Dent
January 2025
Department of Physiology and Pathology, School of Dentistry, São Paulo State University (UNESP), Araraquara, Brazil.
Objectives: To evaluate the color change and trans-amelodentinal cytotoxicity of a 22% carbamide peroxide (CP) bleaching gel containing different concentration of manganese oxide (MnO).
Material And Methods: Enamel/dentin discs adapted to artificial pulp chambers were distributed according to treatments: CN-No treatment; CP22%-22%CP; CP22 + 2MnO-22%CP + 2 mg/mLMnO; CP22% + 6MnO-22%CP + 6 mg/mLMnO; CP22% + 10MnO-22%CP + 10 mg/mLMnO applied for 2 h for 15 days. Color change-CC (ΔE and ΔWI) (n = 8) was determined at 5, 10, and 15-day periods (ANOVA/Sidak).
A Novel Team-Based Approach to Oral Diagnosis Education: Case of the Week.
Eur J Dent Educ
January 2025
Department of Orthodontics and Pediatric and Community Dentistry, College of Dental Medicine, University of Sharjah, Sharjah, UAE.
Background: Traditional oral diagnosis education often relies on passive lectures and individual case assessments. Team-based learning (TBL) offers an interactive alternative, but implementation challenges can exist. The 'Case of the Week (COW)' method presents a potentially modified TBL approach for oral diagnosis education.
