Abstract EN
Background : possibly the greatest deterrent to the development of an ideal restorative material is the leakage that occurs along the restoration, tooth interface.
There is yet no truly adhesive dental material that exactly duplicates physical properties of the tooth structure.
This in vitro study was carried out to compare the micro leakage of two types of restorative materials used in pediatric dentistry Colored light curing composer (Twinky star) and nano ceramic restorative material (Ceram.x)) with that of amalgam by measuring their ability to prevent dye penetration.
Materials and Methods : Standardized Proximo-occlusal cavity preparations were prepared in 30 extracted sound primary first lower molars.
Pulpotomy was performed, and pulpotomy paste filled the pulp chamber with hard setting cement over it all have same occlusal depth.
The teeth were then randomly divided into three groups : Group A : filled with Amalgam.
Group B : filled with compomer (Twinky star).
Group C : filled with nano ceramic (Ceram.x) After that the teeth were stored in distilled water for 30 days at 37 °C in an incubator and during the period of storage the teeth were subjected to 300 thermal cycles (10 cycles each day), then sectioned to be examined under the stereo microscope.
Results : data was analyzed using ANOVA test with help of spas software, even though nano ceramic (Ceram.
X) Showed higher resistance to dye penetration, when compared to compomer (Twinky star and amalgam), there were no significant differences between the three studied groups in their resistance to dye penetration.
Conclusion : depending on the ability to prevent marginal leakage, nano ceramic (ceram.x) and compomer (Twinky star) restorative materials can be used as an alternative to amalgam in restoring pulpotomized primary teeth.
