Injuries to primary teeth occur mostly at
1) 6-12 months
2) 3-4 years
3) 5-6 years
4) 1.5-2.5 years
Pedodontics
Answer: 4
Injuries to primary teeth are most common in children aged 1.5 to 2.5 years, as this is a developmental stage where children are learning to walk and explore their environment, leading to a higher risk of falls and accidents.

2. Crater
3. Fenestration
4. Trough
Pedodontics

The advantage of electrosurgery over blade for gingival tissue management is
1. Rapid postoperative healing
2. Cheaper
3. Less haemorrhage
4. All of the above
The advantage of electrosurgery over blade for gingival tissue management is less hemorrhage.
The primary advantage of external splint compared to internal splint
1. Improved esthetics
2. Increased rigidity to occlusal forces
3. Conservation of tooth structure
4. All of the above
Pedodontics
Answer: 3
The primary advantage of an external splint compared to an internal splint is conservation of tooth structure.

A gingival index of score 2 means
1. Gingiva is healthy
2. Porbing elicits bleeding
3. Unprovoked spontaneous bleeding
4. No bleeding on probing
A gingival index score of 2 means probing elicits bleeding.
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.
In periodontal diseases, alveolar bone loss is the result of
1. Both apposition and resorption
2. Apposition only
3. Resorption only
4. None of the above
Pedodontics
Answer: 4
In periodontal diseases, alveolar bone loss is the result of both apposition and resorption.
