What suture pattern is used to close tooth extraction sites?

• A. Simple interrupted, cruciates
• B. Continuous running
• C. Vertical mattress
• D. Horizontal mattress

Answer: (A)

Closing tooth extraction sites requires precise mucosal edge alignment with controlled tension. Simple interrupted sutures give you exact placement at each point on an irregular socket and allow easy adjustment of tension. When tissue is loose, a cruciate variation helps bring the edges together securely across the socket, providing reliable coverage and reducing the risk of wound opening. Continuous running sutures offer less control over edge placement on uneven wounds, and vertical or horizontal mattress patterns can cinch or evurtle delicate oral mucosa, risking ischemia and drainage problems. So, using simple interrupted sutures with a cruciate component best supports predictable healing of extraction sites.
