2. Failure of occlusal balance bilaterally
3. The force or the pressure beyond the physiological limits to the periodontium
4. None of the above

Occlusal trauma is defined as tissue changes in the periodontium from abnormal occlusal forces.
Which of the following is more common in children
1) Gingivitis
2) Periodontitis
3) ANUG
4) Pericoronitis
Pedodontics
Answer: 1
Gingivitis is the inflammation of the gums that is more common in children due to poor oral hygiene and accumulation of dental plaque. Periodontitis, on the other hand, is a more severe form of gum disease that typically occurs in adults due to prolonged or severe gingivitis. ANUG (Acute Necrotizing Ulcerative Gingivitis) is a specific type of severe gingival infection that is less common in children than gingivitis, and pericoronitis is an infection that occurs around the gum flap when a tooth is partially erupted, which is more common in teenagers and young adults.
An Ellis Class IV crown fracture
1. does not involve the pulp
2. is so extensive that the entire crown has been lost
3. involves only the enamel
4. may expose the pulp
Pedodontics
Answer: 2
An Ellis Class IV crown fracture is characterized by the loss of a significant portion of the crown, often such that the pulp may be exposed. This severe type of fracture requires immediate attention to prevent further damage to the tooth
Ellis Class IV fractures are the most severe form of crown fractures. They extend below the gingival margin and involve the enamel, dentin, and often the pulp. The pulp may be exposed, making it a dental emergency.
