Title Of Article :
THE ROLE OF TEMPERATURE CHANGESWITHIN THE ORAL CAVITY IN CLINICAL FAILURE OF DENTAL RESTORATIONS
Abstract :
The oral cavity is subjected to thermal irritation from hot and cold foods and beverages. Thermal conductivity and thermal expansion of nonmetallic restorative materials, metal, and tooth structures are significantly different. Tooth structures and restorative materials expand or contract with the increase or decrease of temperature in the mouth. In many studies, it was shown that temperature changes in the oral cavity is responsible for the thermal stresses in the restorative materials and the tooth structures when restorative materials that have different thermal expansion coefficients were used. In the same time, these stresses may cause fracture of the dental structure or leakage of the restoration. Therefore, internal stress caused by different thermal expansions and contractions is clinically important. The aim of this study is to exhibit the effects of thermal stresses in clinical failure of the restorations by evaluating the studies about thermal stresses and temperature distribution occurred in dental restorations and tooth structures due to temperature changes in the oral cavity.
