Summary – What is Occlusal Effect Caries (OEC)?
Occlusal Effect Caries (OEC) forms as a result of biofilm formation inside cracks. These cracks are commonly a result of Peripheral Rim Fractures (PRF), which can form due to structural compromise. Bacteria enters through the crack which is located on the occlusal aspect of the tooth, causing caries.
