In a 9-year-old which permanent tooth surface will show greatly increased caries incidence
1) Labial surface of central incisor
2) Occlusal surface of central incisor
3) Mesial surface of central incisor
4) Occlusal surface of lateral incisor
Pedodontics
Answer: 1
In children, the labial (facial) surfaces of anterior teeth, particularly the central incisors, are more prone to caries due to factors such as plaque accumulation, dietary habits, and the developmental stage of the teeth. The labial surface is more exposed to the oral environment and is often less effectively cleaned compared to other surfaces, making it susceptible to decay.
