Brief Summary:
The purpose of this study is to examine and compare the effects of autogenous dental pulp tissue on bone formation in the extraction sockets as compared to commonly used particulate bone graft. The effects on bone formation will be examined using a wide variety of assays.

Arm Intervention/treatment
Experimental: Particulate bone graft plus autogenous dental pulp tissue
Dental pulp will be isolated from teeth extracted for non-periodontal reasons chairside. The isolated dental pulp will be mixed with hydrated particulate bone graft, and the mixture will be placed in the debrided extraction socket. The socket will be covered by a resorbable collagen membrane and sutured.
 Other: Particulate bone graft
Creos allo.gain allogenic bone particulate mineralized cortical bone will be hydrated and placed in the extraction socket.
Other Names:
  • creos allo.gain
  • allogenic bone particulates

Other: Autogenous dental pulp tissue
Dental pulp will be isolated from teeth extracted for non-periodontal reasons chairside, mixed with hydrated particulate bone graft, and then placed in the extraction socket.

Other: Resorbable collagen membrane
After placement of particulate bone graft or particulate bone graft plus autogenous dental pulp tissue, socket will be covered by a resorbable collagen membrane and sutured.

Other: Suture
Resorbable or non-resorbable suture material
Active Comparator: Particulate bone graft
Hydrated particulate bone graft will be placed in the debrided extraction socket. The socket will be covered by a resorbable collagen membrane and sutured.
 Other: Particulate bone graft
Creos allo.gain allogenic bone particulate mineralized cortical bone will be hydrated and placed in the extraction socket.
Other Names:
  • creos allo.gain
  • allogenic bone particulates

Other: Resorbable collagen membrane
After placement of particulate bone graft or particulate bone graft plus autogenous dental pulp tissue, socket will be covered by a resorbable collagen membrane and sutured.

Other: Suture
Resorbable or non-resorbable suture material
