RESUMEN
BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is an intense negative drug response causing increasing bone destruction in the maxillofacial area of patients. AIMS AND OBJECTIVES: To evaluate the knowledge and attitude of dental practitioner regarding risk factors of MRONJ in Saudi Arabia. MATERIALS AND METHODS: A cross-sectional, questionnaire survey was carried out in King Khalid Hospital, Al-Kharj among dental practioners. RESULTS: Approximately 60% of the practioners had a poor knowledge and there was a weak positive correlation with work experience. CONCLUSION: Poor knowledge regarding the MRONJ invites a continuing dental education specially to focus on general practioners.
RESUMEN
The conventional denture base resins had many drawbacks. Hence, the objective of this study was to compare the effect of incorporation of silver nanoparticles on mechanical properties of light-cured resin material. MATERIALS AND METHODS: Specimens of acrylic resin (control group) and acrylic resin reinforced with 2% silver nanoparticles (test group) were evaluated for mechanical properties such as impact strength, transverse strength, modulus of elasticity, and deflection. Unpaired t test was used for statistical analysis. RESULTS: Mechanical properties of light cure reinforced with silver nanoparticles were significantly higher than conventional light-cured resin (P < 0.05). CONCLUSION: The incorporation of silver nanoparticles into light-cured resin increases the mechanical properties making it more stronger material.
