socket preservation using biodentin versus xeno graft for single rooted mandibular teeth

after extraction of single rooted mandibular teeth the socket will be filled with xeno graft or biodentine and the socket will be closed using gel foam and sutures then CBCT will be taken to measure bone width after 6 months of healing CBCT will be taken again to measure the difference in bone width and a core biopsy will be taken followed by implant placement

Inclusion Criteria:

• Patients of both sex with badly decayed tooth indicated for extraction
• The ages of the patients ranged from 25 to 50 years.
