Dentistry Journal, Journal Year: 2025, Volume and Issue: 13(4), P. 140 - 140

Published: March 25, 2025

Background: Peri-implantitis, the most prevalent cause of implant failure, is a multifaceted issue that influenced by various factors promote biofilm formation around implant. Although innovative methods for microbiological decontamination dental implants exist, universally accepted standard protocol has not yet been established. However, potential device generates an electric current (Ximplant®) in reducing survival microorganisms within promising development. Methods: In this vitro study, five implants, contaminated using microbial culture from sample saliva patient suffering peri-implantitis, were decontaminated Ximplant® peri-implantitis protocol. The experimental conditions included simulated peri-implant site and subsequent fluorescent assessment Live/Dead population. Results: qualitative quantitative image analyses showed predominant dead light signal on treated sample, demonstrating efficacy applying electrostatic field to surface viability implants. Conclusions: These findings could inspire new era treatment.

Are Dental Magnetic Resonance Imaging and Ultrasound Techniques reliable alternatives for treatment planning Dental Implants? A Systematic Review and Meta-Analysis

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: May 6, 2025

Background The rising global demand for dental implant highlights the necessity precise imaging techniques that minimise patient risk of radiation exposure. While cone -beam Computed Tomography (CBCT) remains gold standard, its ionizing exposure raises safety concerns. This systematic review and meta-analysis aim to evaluate accuracy non-ionizing alternatives, Magnetic Resonance Imaging (MRI) Ultrasonography, in implantology. Methods Databases (MEDLINE, Scopus, Cochrane) were searched studies (2014–2024) using predefined PICO criteria. Risk bias was assessed via QUADAS-2. Meta-analysis employed fixed/random-effects models synthesize quantitative data on geometric deviations soft-tissue accuracy. Results Twelve included this study. MRI generally exhibited greater deviation tip placement at 0.3mm (95% CI -0.08, 0.68), overall remained comparable CBCT. showed a higher mean entry level 0.38mm 0.04, 0.71) angulation with difference 0.81 degree -0.50, 2.12), indicating less precision under specific conditions. Conversely, Ultrasonography demonstrated superior performance soft tissue smaller compared CBCT, just 0.04mm -0.04, 0.13). Conclusion ultrasonography offer reliable alternatives planning, matching CBCT hard-tissue excelling assessment. Further standardisation protocols is needed address variability clinical workflows.

Introduction: Dental implants enhance the self-assurance and overall well-being of individuals by providing oral comfort during mastication a notable degree contentment. The objectives present study were to assess patients' perception opting or non-opting for dental as replacement missing teeth determine correlation between various factors perceived demand implant treatment. Materials methods: A cross-sectional observational was conducted on 214 partially edentulous aged 21 50 years. These patients sought treatment replace their teeth. participants provided with detailed information regarding options replacing teeth, including removable prostheses, fixed partial dentures, implants. researchers recorded evaluated reasons behind decision opt decline using chi-squared test. Categorical variables summarized percentages (n %). association binary data examined point biserial correlation, whereas, continuous data, Pearson coefficient employed. Results: About 65 (30.4%) opted 149 (69.6%) did not Missing found in 120 women (56.08%) 94 men (43.92%). main reason seeking need improvement functions such chewing (100%) patients, followed health 57 (88%), aesthetics 54 (83%), bone adjacent preservation 52 (80%), durability 46 (71%) patients. prostheses other than cost (100%), fear surgery 132 (91%), underlying issues 121 (81%), lack knowledge about (80.5%), time management 92 (62%).
