Abstract

Fiber reinforced composite (FRC) is widely used to replace porcelain fused to metal (PFM) for patients who have lost teeth. Fiber reinforced composite is resin matrix protheses with fiber reinforced to get optimal strength. Glass fiber dental is often used because it does not require complex preparations, not sensitive to chemicals and moisture, but it has an expensive price for Indonesian people and limited availability. An alternative material such as glass fiber non dental can used. Mouthwash is used as an antiseptic and anti-plaque material on the oral cavity. Mouthwah can affect of water sorption of FRC. The aim of this study is to know effect of mouthwash on the absorption of water in non dental glass fiber - reinforced FRC. Sixty specimens divided into four groups (n=4), 2 groups with glass fiber dental soaked on the bisguanida and aquades, 2 groups with glass fiber non dental soaked on the bisguanida and quaternary ammonium. The data analyzed with Anova. Anova test showed that there is an influence of mouthwash bisguanide and quartenary ammonium compounds on the value of absorption of glass fiber reinforced composite water (p<0,05). Water sorption of FRC in bisguanide mouthwash is higher than quartenary ammonium compounds.

Abstract

Background: Dental fibers were first introduced by Smith (1960) which are used in various fields of dentistry. Dental fibers are classified into two categories, natural and synthetic. Glass fiber that is often used in dentistry is E-glass fiber because of its resistance to chemical reactions, has good aesthetic properties, has almost the same mechanical properties as dentin and is biocompatible. In the oral cavity, acidic conditions occur due to consumption of food and beverages containing acid. Acidic conditions in the oral cavity can affect the mechanical properties of the composite resin. Factors that affect the mechanical properties of fiber reinforced composite are the properties of the composite material and fiber used, fiber quantity, fiber position, fiber direction, fiber adhesion to the composite matrix. To determine and study the effect of acidic pH on the mechanical strength of e-glass fibers. Method: This type of research is a literature review using a systematic review approach.Result: The decrease in compressive strength and resistance was influenced by structural disturbances and loss of most components due to acid exposure. The decrease in the tensile strength of the glass fiber increases the time associated with immersion of the fiber surface which can interfere with the continuity of the e-glass network. Acidic drinks, carbonated drinks, and alcohol can produce erosion on the surface of the composite resin. The longer the immersion, the more solution particles that enter the resin microporosity space and reduce the strength of the composite resin.Conclusion: The mechanical strength of e-glass fiber will decrease with the length of exposure to acid. Types of acids that can affect the decline in mechanical strength are strong acids such as hydrochloric acid (HCl), sulfuric acid (H2SO4), nitric acid (HNO3), and phosphoric acid (H3PO4).
