Answer: 4
Preeruptive caries refers to carious lesions that develop on teeth before they have erupted into the oral cavity. Research indicates that the mandibular second molars are particularly susceptible to preeruptive caries due to their position and the timing of their eruption. They are often more difficult to clean and can be affected by factors such as the presence of other teeth and the oral environment
