Retrograde root filling with amalgam and Cavit

Area of Science:

• Endodontics
• Dental Materials Science

Background:

• Retrograde root filling is a common endodontic procedure.
• Amalgam and Cavit are frequently used materials for retrograde root fillings.
• Incomplete orthograde root fillings may require revision, especially with posts.

Purpose of the Study:

• To compare the clinical success of retrograde root fillings using amalgam versus Cavit.
• To evaluate the influence of marginal bone loss on the outcomes of retrograde root fillings.

Main Methods:

• A 3-year retrospective review of 218 teeth.
• Teeth were treated with retrograde root filling using either amalgam or Cavit.
• Outcomes were assessed, considering factors like marginal bone loss.

Main Results:

• Amalgam fillings demonstrated significantly better results than Cavit fillings.
• Superior canal obliteration by amalgam is suggested as the reason for better outcomes.
• Results were less favorable in cases with existing marginal bone loss, regardless of filling material.

Conclusions:

• Amalgam is a superior material for retrograde root fillings compared to Cavit.
• Effective canal obliteration by amalgam may reduce the need for revision of incomplete orthograde root fillings.
• Marginal bone loss negatively impacts the success of retrograde root fillings.
