Discoloration of nano composite resin by everyday drinks:in vitro study
The everyday consumption of various drinks has immediate affect on the composite resin materials extrinsic look. This changes mainly manifest as a change in the aesthetic appearance of human teeth which is why thru scientific researches we need to eliminate the possibility of such discolorations. For this research were made 30 discs of nano composite resin material Artiste, 2 mm thick and 15 mm in diameter. As colorants were used drinks like red wine, coca cola, filter coffee, aronia tea and distilled water as control group. Three color measurements were made by spectrophotometer X-RITE RM 200 which results will be used as basic, middle and final discoloration change on the composite discs. The results were evaluated thru the CIE L*a*b* system for colorimetric analysis which specified the warm colorants lead to rather bigger discolorations than the ones used on room temperature. The biggest discoloration was noticed in tea (ΞE*=31,83) followed by coffee (ΞE*=23,23) and wine (ΞE*=19,11). Coca cola (ΞE*=0,28) was the only colorant that did not cross the clinically acceptable threshold of Ξ2.7. Within the limitations of this study was acknowledged that some everyday drinks have rather bigger discoloration effect on the composite resin materials than others.

The effect of every day drinks on composite restorations aesthetics: in vitro study
Abstract:
Aim: The main objectives of this in vitro study is, within its limitations, is to evaluate whether every day drinks affect the aesthetics of the dental composite resin materials.
Method: Thirty microhybrid composite resin (Gradia Direct) discs were made (15 mm in diameter and 2mm thick) and randomly divided into five groups. The groups were immersed in colorants as red wine, coca-cola, filter coffee, aronia tea and distilled water as control group. Spectrophotometer X-RITE RM 200 was used to follow the changes in color with three measurements, first one at the beginning (baseline), second at the middle, third at the end of the research. Each group was immersed in its colorant twice a day for the duration of the study. The received data was analyzed according the CIE L*a*b* color system.
Result: Three out of four colorants have surpassed the clinically acceptable threshold of discoloration which is Ξ2.7. Significant discoloration was observed with the warm drinks compared with the ones used on room temperature. The tea caused most significant discoloration (Ξ22.17) followed by coffee (Ξ16.73) and wine (Ξ12.10). The drink that cased the least discoloration was the coca-cola (Ξ1.24).
Conclusion: The color stability of the composite resin restorations is affected by the everyday drinks that are consumed, from some more than others.

Composite resin discoloration caused by every day consumption products
Background: Composite resins revolutionized the modern restorative dentistry with its high value aesthetic properties especially in the frontal region, and satisfactory stability in the posterior region of the human dental arch. The aim of this poster presentation is to serve us as a reminder about the possible staining of the composite resins immersed into various drinks, food colorants and dental rinse products.
Methods and materials: For this type of research we used a number of scientific articles from the database of PubMed which dated from the year of 2009 until present time. We used only articles that had in vitro researches on plain composite resin based restorative materials which are most used in dental practices around the world.
Results: All the articles showed a small to a significant discoloration of the composite resins no matter of the chemical compound of the resin matrix, or the finishing technique. For any discoloration to occur there are many intrinsic and extrinsic causes which vary from resin to resin.
Conclusion: Composite resins are prone to discoloration (and wear) which occurs from the substances that are part of our every day consumption products. Discoloration can be slowed down with proper placement of the resins into the cavities, and adequate techniques of finishing and polishing
Modified Direct Composite Resin Bonded Bridge
Introduction. After losing a tooth in the anterior region the patients immediately seek a solution for this newly occurred problem. Should the indications be right, a resin bonded bridge enforced with glass fibre tape can be proposed as an aesthetic treatment option .
Case Description. A patient came to our clinic for a treatment after losing a left central lower incisor. After examining the patient, several options like prosthetic and surgical with prosthetic were proposed, but she declined them all. At last a resin bonded bridge was chosen as an option due to the aesthetic that it provides and the minimally invasive technique. A full mouth ultrasonic scaling was conducted prior to the treatment for optimal conditions. The adjacent teeth were etched with a 37 % phosphoric acid for 60 seconds. After the etching the teeth were rinsed off from the acid and kept dry for the entire treatment. On the etched surface a 7-th generation bond was applied and polymerized. A glass fiber tape was adapted and bonded on the surfaces off the adjacent teeth. Tooth like structure was build around the fiber glass tape with a micro-hybrid composite resin. The treatment ended with finishing and polishing the structure as well as instructions for the patient on how to maintain the resin bonded bridge.
Discussion. The adhesion that provides the 7-th generation bond and the glass fiberβs strength will play the key roles for the longevity off this structure
