ABSTRACT
Introduction: The aim of this study was to assess the knowledge of general dental surgeons on the criteria for choosing the cervical margin in fixed prostheses in dental practices in Bamako and Kati. Methodology: This was a prospective descriptive study focusing on 73 general dental surgeons in dental practices in Bamako and Kati over a period of three months, from July to September 2025. Data were collected using a self-administered survey form given to practitioners. Results: The participating dentists represented a rate of 93.59%. Males represented a rate of 72.6%. The sex ratio was 2.63 (M/F). The 30-40 age group represented 53.4% of cases. Average: 33.78 years; Standard deviation: 4.98 years; Extremes: 27 and 46 years. Private dental practices were the most represented, accounting for 41.1% of cases. In our study, 34% of participants had completed other training courses. The number of years of experience was < 5 years in 46.6% of cases. Average: 6.96 years; Standard deviation: 4.26 years; Extremes: 1 and 15 years. The majority of participants were in the private sector, representing 72.7% of cases. The depth of the metal-ceramic crown was between 1.2 and 1.5 mm in 60.3% of cases. Shouldering accounted for 32.9% of cases for metal-ceramic crowns. The margin was between 0.8-1 mm in 61.7% of cases for metal crowns. The margin was recessed in 43.9% of cases for metal crowns. During the study, 58.9% of participants mentioned a depth between 0.8-1 mm for a zirconia crown. The chamfer margin was represented in 34.3% of cases for a zirconia crown. The margin was subgingival in 65.8% of cases to meet patients' aesthetic demands. The shoulder bur was used in 57.6% of cases for shoulder preparation. The chamfer bur was used in 57.6% of cases for chamfer repair. The pointed conical bur was used in 65.8% of cases for tracing preparation. The pointed conical bur was used in 50.7% of cases for highlighting undercuts. The margin was subgingival in 65.7% of participants for a m

ABSTRACT
Odontogenic infections represent a significant public health concern due to their high prevalence and potential for severe complications. These conditions commonly arise as a consequence of dental caries and periodontal disease, which remain leading causes of oral pathology worldwide.¹ In many cases, effective management requires an integrated approach combining pharmacological, dental, and surgical interventions², tailored to the specific clinical circumstances. The infection may originate within the dental structures or extend to the surrounding tissues. When the inflammatory process cannot be effectively controlled through antibiotic therapy, it may disseminate to the subcutaneous regions and, in severe cases, manifest extraorally.³ Such infections frequently present with pain and swelling in the orofacial region, often necessitating emergency endodontic intervention to alleviate symptoms and control the spread of infection.⁴ In patients exhibiting acute pain and clinical signs of facial swelling, endodontic management typically involves root canal treatment in conjunction with systemic antibiotic therapy.¹,²,³,⁴ Clinical Case: A 20-year-old male patient presented to the UABC Polyclinic in Mexicali with intense pain in the right submandibular region and noticeable right-sided facial asymmetry. Pulpal diagnosis: necrosis. Periapical diagnosis: acute periapical abscess affecting tooth #46. Endodontic treatment was initiated to achieve internal decompression, followed by completion using the crown-down biomechanical instrumentation technique, irrigation with 5.25% sodium hypochlorite (NaOCl), and obturation with MTA-Fillapex sealer. The clinical outcome was favorable, demonstrating complete resolution of the infection and absence of recurrence during follow-up.

ABSTRACT
Introduction: Acquired maxillofacial defects, most often of tumoral origin in West Africa, have major functional, aesthetic and psychological consequences. Maxillofacial prosthesis (MFP) remains the main rehabilitation option in Senegal, but local data on the lived experience of patients are scarce. The aim of this study was to assess satisfaction and the psychosocial impact of MFP in patients followed at IOS-UCAD. Methods: A descriptive cross-sectional study was conducted on 60 patients fitted with an MFP, recruited consecutively at the Prosthetics Department of IOS-UCAD in Dakar, from April to July 2025. Sociodemographic, clinical and prosthetic data, as well as satisfaction and psychosocial impact, were collected using a face-to-face questionnaire. Results: Mean age was 42.5 ± 18.8 years, with a female predominance (60.0%). The defect was of tumoral origin in 91.6% of patients. The MFP was maxillary in 90.0% of cases. Overall satisfaction reached 93.3%. Aesthetic (85.0%) and phonatory (85.0%) satisfaction was high; masticatory function remained the lowest-rated dimension. The patient–caregiver relationship was rated fully satisfactory by all patients on the five criteria assessed (100.0%). The psychosocial impact was positive: 96.7% of patients reported feeling at ease with themselves and having regained self-confidence; 93.3% reported improved social integration. Conclusion: MFP provides a rehabilitation considered satisfactory by the great majority of Senegalese patients and restores a quality of life compatible with social reintegration. Masticatory satisfaction is the main area for improvement. The expansion of MFP services within the Senegalese hospital network should be strengthened.

ABSTRACT
Aim of the Study: To compare the inhibitory antimicrobial effect of ginger, cinnamon, pomegranate peel extracts against Enterococcus faecalis. Streptococcus mutans, Staphylococcus aureus and Candida albicans. Materials and Methods: Fresh ginger, cinnamon and pomegranate peel were freshly purchased and accordingly prepared for 15% ethanolic extracts, subjected to microbiological assays to determine zones of growth and/or inhibition against Enterococcus faecalis, Streptococcus mutans, Staphylococcus aureus and Candida albicans. Results: Statistically significant antimicrobial inhibitory potential of Enterococcus faecalis, Streptococcus mutans, Staphylococcus aureus and Candida albicans were observed between and within the different extracted materials and the positive and negative control groups (p=0.000). The antimicrobial inhibition zone was significantly exhibited in the cinnamon extract group compared to the ginger and pomegranate peel groups, especially against Streptococcus mutans and Candida albicans, compared to the other groups. While staphylococcus aureus demonstrated substantial inhibitory effect towards pomegranate and cinnamon, whereas Enterococcus faecalis showed similar inhibitory zones with cinnamon and pomegranate. Conclusion: Cinnamon, Ginger, and Pomegranate exhibited prominent antibacterial inhibitory effects that hold potential for preventive and therapeutic applications. Particularly, Cinnamon showed the most significant antimicrobial activity against Streptococcus mutans and exhibited an anti-candidal inhibitory effect. Clinical Significance: The clinical significance of the antimicrobial effects of ginger, cinnamon, and pomegranate lies in their potential as natural alternatives or adjuncts to conventional antimicrobial agents, especially in the face of rising antibiotic resistance.

ABSTRACT
3D printing, or additive manufacturing, has revolutionized modern dentistry by enabling precise, customizable, and rapid fabrication of dental devices and anatomical models. Its applications span prosthodontics, orthodontics, oral and maxillofacial surgery, endodontics, and regenerative dentistry, facilitating the production of crowns, dentures, aligners, surgical guides, and tissue scaffolds with high accuracy. Despite these advancements, challenges such as material limitations, cost constraints, regulatory hurdles, and the need for specialized training continue to restrict its widespread adoption. Looking forward, innovations in biocompatible materials, multi-material printing, and integration with digital dentistry tools, including CAD/CAM systems and artificial intelligence are expected to enhance personalized dental care and expand regenerative and chairside applications. This review comprehensively examines the current clinical applications, limitations, and future perspectives of 3D printing in dentistry, highlighting its transformative potential in improving patient outcomes and shaping the future of dental practice.
