Juvenile periodontitis (now referred to as localized aggressive periodontitis)
is characterized by localized bone loss and periodontal pockets, often affecting
adolescents and young adults. The sudden drifting of teeth and the severity of
bone loss in specific areas align with this diagnosis.

Most commonly used desensitising agent
1) Iontophoresis
2) 2 % Fluoride
3) Formalin
4) Sodium hypochloride
Periodontics
Answer: 2
2% fluoride is one of the most commonly used desensitizing agents in dentistry. It works by strengthening enamel and reducing the permeability of dentin, which helps alleviate sensitivity in teeth. Fluoride treatments are widely used in clinical practice to manage dentinal hypersensitivity effectively.
