Each material was syringed into a brass mold with an inner diameter of 6 mm and a thickness of 2 mm. The replacement of lost tooth structure is usually desired to restore esthetics and function for which various esthetic restorative materials are used.
The pre and post immersion surface roughness values were recorded using a profilometer. The mold, with specimen material, was held between two glass slides and covered with a transparent polyester strip.
Frequent consumption of these easily and widely available carbonated beverages and fruit juices showed erosion of the enamel both in vitro and in vivo. Other factors responsible for this significant erosion were also discussed.
Erosion is a common condition which manifests due to consumption of high caloric and low pH acidic food stuffs such as carbonated drinks and fruit juices which cause irreversible damage to dental hard tissues and early deterioration of the dental restorations. The materials were polymerized for 30 s using a quartz tungsten-halogen light Astralis 3, Ivoclar Vivadent Inc.
Giomer, a true hybrid of glass ionomer and resin composite having properties like fluoride-release and recharge of glass ionomer cements plus excellent esthetic properties, good surface finish and strength characteristics similar to resin composites. In spite of many advantages like chemical bonding and fluoride-releasing property their moisture sensitivity, low mechanical strength and poor wear resistance made them less durable.
The main aim of this study is to evaluate and to compare the erosive potential of carbonated drink cola and fruit juice orange fruit juice by measuring the surface roughness Ra values on two commonly used dental restorative materials.
Specimens were finished and polished with Sof-Lex disks 3M, St. Significant surface changes of the dental restorative materials can take place when exposed to low pH drinks for a prolonged period. The glass slide was held firmly during setting to avoid the presence of air bubbles and to obtain a smooth surface.
Thus, the aim of this study is to evaluate changes in surface roughness of tooth colored filling materials compomer and giomer after immersion in various acidic drinks that represent popular diets and have the potential to cause dental erosion in the oral cavity.
Compomer showed more surface roughness when compared to giomer when exposed to the three tested media which can be attributed to the variation in filler content, decomposition of resin matrix and fallout of the fillers in composites when exposed to acidic drinks.
Dental erosion is defined as an irreversible loss of dental hard tissue by a chemical process without the involvement of microorganisms and is due to either extrinsic or intrinsic sources.
Six specimens in each group were discarded due to wide variation in pre exposed Ra values and the remaining 30 specimens in each group were further sub divided into 10 samples each according to the testing media used.
Extrinsic causes include acidic substances, beverages, medication and environmental exposure to acidic agents. Immersion regime was followed according to Von Fraunhofer and Rogers.
A total of 36 specimens each were prepared using both testing materials, compomer Group I and giomer Group II. Compomer, Erosion, Giomer, Orange fruit juice, Profilometer, Soft drink, Surface roughness Introduction Over the last few decades, there was a drastic decline in the prevalence of dental caries world-wide which has been accompanied by a remarkable increase in the incidence of non-carious lesions such as dental erosion.

Sucking frozen fruit juices could be more erosive than unfrozen fruit juices because of increase in buffering capacity of initial thawed juice .
The acidity increases on freezing, as the physical state of the residual juice changes. When juice is frozen, water alone is solidified to ice without the solute. erosion seems to have increased presumably due to an increase in the consumption of soft drinks and fruit juices.
 According to American dietetic association, it is estimated that 40% of preschool children consume ml of carbonated beverage/ day. The erosive effects of fruit juices have been recognized way back in by Darby. Citrus fruit juices are the nutrients rich in vitamins, minerals and dietary fibres necessary for normal growth and development and healthy nutrition.
Along with their high nutritional value, these citrus fruit juices may show an erosive effect on teeth enamel due to the fact that they contain citric, malic, tartaric, benzoic and oxalic acid.
Erosive potential of different types of grape juices Abstract: The purpose of the present study was to evaluate the erosive potential of different types (concentrated and powdered) and commer-cial brands of industrialised grape juices.
The pH of all five fruit drinks was measured at two time points: immediately after preparation and 24 hours later.
Diets that may pose an erosive risk to the teeth are those that include an unusually high consumption of citrus fruits, fruit juice and carbonated soft drinks. In addition, there has been increasing concern to adopt a healthy diet (including fruits, vegetables and fruit juices) which has led to increased consumption of acidic foods and drinks .Download
