Denture cleanliness and hygiene: an overview.

Dentures are an excellent treatment modality for partial and edentate patients; however, improper denture care and hygiene can result in both decreased longevity of the prosthesis and increased risk of developing dental caries, periodontal disease and oral candidosis. Previously, it has been shown that patients and dental professionals are unaware of the different materials and methods available for optimum denture care and hygiene. This article provides an overview of the key legislation and main commercially available methods for denture cleanliness and hygiene, and serves as a basis for providing tailored denture hygiene for denture wearers.

An ex-vivo model to determine dental pulp responses to heat and light-curing of dental restorative materials.

Aim: Based on histological studies from the 1960s, it is recommended that dental pulp temperature increases should not exceed 5.5 °C. However, no contemporary reliable models exist to explore the effects of heat on living dental pulp.

The effectiveness of adhesives on the retention of mandibular free end saddle partial dentures: An in vitro study.

Objectives: Existing in vitro methods for testing denture adhesives do not fully replicate the complex oral geometries and environment; and in vivo methods are qualitative, prone to bias and not easily reproducible. The purpose of this study was to develop a novel, quantitative and more accurate model to test the effect of adhesives on the retentive force of mandibular free end saddle partial dentures.

Methods: An in vitro model was developed based on an anatomically accurate cast of a clinical case.

Effect of Preoperative Occlusal Matrices on the Vickers Microhardness of Composite Disks Polymerized with QTH and LED Lamps.

Purpose: This study aimed to assess the reliability of the preoperative occlusal matrix technique in terms of the surface Vickers microhardness (VMH) of the underlying composite restorative material.

Materials And Methods: Two hundred microhybrid composite cylinders were built up and light-cured in a single-layer step, forming two experimental groups (N = 100) according to their heights (1.5 mm/2 mm).

Virulence and pathogenicity of Candida albicans is enhanced in biofilms containing oral bacteria.

This study examined the influence of bacteria on the virulence and pathogenicity of candidal biofilms. Mature biofilms (Candida albicans-only, bacteria-only, C. albicans with bacteria) were generated on acrylic and either analysed directly, or used to infect a reconstituted human oral epithelium (RHOE).

Improving some selected properties of dental polyacid-modified composite resins.

Objectives: Polyacid-modified composite resins (compomers) are restorative dental materials that exhibit certain features of traditional dental composites and glass-ionomer cements. The aim of this paper was to develop experimental compomers with enhanced properties, based on adhesive monomers vinyl phosphonic acid and pyromellitic dianhydride glycerol dimethacrylate, and to compare their properties to those of commercially available products.

Methods: Factorial experimental design was employed to optimize both chemical and physical properties.

An assessment of shade taking by dental undergraduates.

This study investigated the shade recording abilities of dental students using the traditional methods and that incorporating a colour correcting device to that of a digital shade recording device. Shade matching ability was evaluated between different groups of students at Malmö and Cardiff. The use of the colour correcting device improved a student's ability to match shades when compared to the traditional method under normal lighting conditions.
