ABSTRACT Polished dentures obtained from the laboratory require adjustment during insertion. A smooth surface on acrylic resin can be obtained using a chairside protocol for polishing using silicone polishing agents and polishing media. The aim of this paper is to study the effect of three different polishing agents-pumice, universal polishing paste and Brite-O on the surface finish and hardness of two types of denture base acrylic resins-auto polymerizing and heat-activated acrylic resin materials.

The Impact

ABSTRACT The denture bases made by using polymethyl methacrylates of Acrylic resin family have excellent physical properties, simple to process and easy to reline, rebase and repair. One of the inherent disadvantages of this material is the liability to break during function. The strength assessment of acrylic resins have been made generally by transverse deflection tests. Aim To evaluate the impact strength valves of certain brands of commercially available denture base resins and suggest their suitability. Materials and methods The denture bases we made using polymethyl methacrylates of acrylic resin family because they have excellent physical properties, simple to process and easy to reline and rebase. Six commercial brands of polymethyl methacrylate, namely Stellon (DPI-India), Acralyn-H (Asian Acrylate, India), Trevalon (Dentsply-England), Lucitone 199 (Dentsply/ York division), Acralyn-H (Super Unbreakable), Trevalon HI (Dentsply, Detray division, England) were tested by breaking them using Analog Pendulum (ASTM D 256). Results From the entire study the maximum impact strength was reported for Acralyn-H super unbreakable (Asian Acrylates, India) 62.19 joules. Conclusion All the analysis led to conclusion that there is basic change in material composition within and among the different groups of denture base resins. Clinical implications The complete dentures made using denture base resins with high impact strength valves (e.g. Acralyn-H super unbreakable) will be more durable and can be used by the patient for considerable period of time, i.e. beyond 4 to 5 years.

Surface Changes

Early forms of toothbrush have been in existence since 3000 BC. Several changes have happened since then, it has evolved from a‘chew stick’, into a bristle toothbrush, then a battery-operated toothbrush. Tooth brushing has been our primary way of cleaning theoral cavity and its structures to maintain good oral hygiene. However, prolonged brushing can be abrasive to one’s existing restorationand prosthesis increasing the surface roughness, leaving the resins vulnerable to damage and plaque accumulation. This study aims toevaluate the effect of tooth brushing using a manual toothbrush and a battery-operated toothbrush to the surface roughness ofcomposite resin restorations and denture base acrylic resin. Composite specimens and denture base acrylic specimens showed varyingwear and surface roughness with several variables taken into consideration such as brushing force, brushing stroke, dentifrice, type ofbristle, and type of toothbrush used. The expected result is that the specimens brushed using the battery-operated toothbrush withapplied toothpaste will have greater wear and surface roughness.
