Pedodontics
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

📝 Explanation:

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.

Pedodontics
Deviations in which of the following stages of development of the dentition result in supernumerary teeth?
1. Apposition
2. Morphodifferentiation
3. Initiation
4. Multiplication

📝 Explanation:

Supernumerary teeth, or extra teeth beyond the normal complement, typically arise from deviations during the initiation stage of dental development. This stage involves the formation of the dental lamina, which is responsible for the development of teeth. Abnormalities in this process can lead to the formation of additional teeth.
