    The impact of new complete dentures on oral health-related quality of life
    (South African Dental Association, 2007) Adam, R.Z.; Geerts, Greta; Lalloo, R.
    OBJECTIVE: To investigate the relationship between complete dentures and oral health-related quality of life (OHRQol). METHOD: Seventy-six patients were conveniently selected from the waiting list for complete dentures. At the first visit (pre-treatment) the patients were interviewed using the Ora Health Impact Profile for Edentulous Patients (OHIP-EDENT). Sixty-three of these patients were interviewed telephonically 2 to 3 months after receiving their new complete dentures (post-treatment). RESULTS: Mean domain scores were significantly lower post­ treatment for psychological discomfort and disability, social disability and handicap. CONCLUSION:This study shows that after the provision of a new set of complete dentures the OHRQoL of patients im­proved significantly on four of the seven domains for the first 2 to 3 months post-insertion.

    Recent Advances in the Development of Antimicrobial and Antifouling Biocompatible Materials for Dental Applications
    (MDPI, 2021) Ramburrun, P.; Pringle, N.A.; Dube, A.; Adam, R.Z.
    The risk of secondary bacterial infections resulting from dental procedures has driven the design of antimicrobial and antifouling dental materials to curb pathogenic microbial growth, biofilm formation and subsequent oral and dental diseases. Studies have investigated approaches based primarily on contact-killing or release-killing materials. These materials are designed for addition into dental resins, adhesives and fillings or as immobilized coatings on tooth surfaces, titanium implants and dental prosthetics. This review discusses the recent developments in the different classes of biomaterials for antimicrobial and antifouling dental applications: polymeric drug-releasing materials, polymeric and metallic nanoparticles, polymeric biocides and antimicrobial peptides. With modifications to improve cytotoxicity and mechanical properties, contact-killing and anti-adhesion materials show potential for incorporation into dental materials for long-term clinical use as opposed to short-lived antimicrobial release-based coatings. However, extended durations of biocompatibility testing, and adjustment of essential biomaterial features to enhance material longevity in the oral cavity require further investigations to confirm suitability and safety of these materials in the clinical setting. The continuous exposure of dental restorative and regenerative materials to pathogenic microbes necessitates the implementation of antimicrobial and antifouling materials to either replace antibiotics or improve its rational use, especially in the day and age of the ever-increasing problem of antimicrobial resistance.
