Skeletal Maturity Indicators Short Essays

Question 1. Hand Wrist Radiograph.
Answer.

It is one of the skeletal maturity indicators

Significance Of Hand Wrist Radiograph:

• Describes ossification and union of small bones of hand and wrist
• Determines skeletal age of patients

Indications Of Hand Wrist Radiograph:

• In the discrepancy between dental and chronological age
• Determines the skeletal age of the patient
• Determines skeletal malocclusion
• Predict future skeletal growth
• Predict pubertal growth spurt
• Aid in research
• Assess the growth status of individual

Methods Of Hand Wrist Radiograph:

• Atlas method by Greulich and Pyle
• Bjork, Grave, and Brown’s method
• Fishman’s skeletal maturity indicator
• Hagg and Taranger’s method

Anatomy Of Hand Wrist:

Consist of:

• Distal ends of long bones of the forearm
• Carpals
• Metacarpals
• Phalanges

Question 2. Maturity Indicators.
Answer.

Importance Of Maturity Indicators:

• Determine the stage of maturity
• Assess skeletal growth
• Decides the treatment planning
• Helps in objective diagnosis
• Assess different ossification centers

Methods Of Maturity Indicators:

• Hand wrist Radiograph
• Cervical vertebrae
  • By Hassel and Farman
