DANB's Restorative Functions Sample Test

1 of 5

Which of the following is the process from which an amalgam will repeatedly expand and contract in the oral cavity? 





Correct Answer:
percolation


the correct answer to the question is "percolation." percolation in the context of dental restorations, particularly amalgam, refers to the process where there is repeated expansion and contraction due to temperature changes in the oral cavity. this phenomenon leads to the opening and closing of gaps between the dental restoration and the tooth structure.

amalgam, a common material used in dental fillings, expands and contracts in response to the thermal changes associated with the intake of hot or cold foods and beverages. when a dental amalgam undergoes these temperature fluctuations, it slightly changes in size. however, the tooth structure itself also expands and contracts but at a different rate compared to the amalgam. this differential in expansion and contraction rates can lead to microscopic gaps or spaces at the interface between the tooth and the amalgam filling.

the opening of these gaps, even if microscopic, can allow for the movement of fluids and bacteria in and out of the space between the tooth and the filling. this movement is referred to as percolation. the fluids that enter these gaps can potentially cause further damage, such as decay under the filling or further weakening of the tooth structure. additionally, the continuous process of expansion and contraction can weaken the bond between the amalgam and the tooth, potentially leading to the failure of the restoration.

understanding percolation is important for dental professionals when considering the longevity and effectiveness of amalgam restorations. it informs the need for careful choice of materials and techniques that can minimize this effect, thereby extending the life of the filling and maintaining oral health.
