Background and aims. The accelerating effect of plasma rich in growth factors in the healing of extraction sockets has been shown by some studies. The aim of the present investigation was to evaluate the effect of deproteinized bovine bone matrix (DBBM) with and without plasma rich in growth factors (PRGF) in canine extraction socket.

Materials and methods. Distal roots of second and third upper premolars were extracted bilaterally in six mongrel dogs. Buccolingual (BL) and apico-coronal (AC) dimensions of extraction sockets were measured. The extraction sockets were randomly grafted with DBBM+PRGF or DBBM. The ungrafted extraction sockets were allowed to be filled with clot which served as control. The dogs were sacrificed after 3 months and the extraction sockets were evaluated from clinical and histological viewpoints.

Results. There were significant differences in post extraction vertical dimensions of the sockets among the study groups. The mean AC changes were 6.25±2.13 mm, 6.83±1.83 mm, and 3.83±1.63 mm in DBBM, BDDM+PRGF, and control groups, respectively (P=0.034). The mean BL dimension reduction in both DBBM+PRGF and DBBM groups was 2.00±1.09 mm, whereas this amount was 2.66±1.47 mm in the control group (P=0.627). The greatest amount of bone resorption occurred in the control group whereas the PRGF group exhibited the least amount of bone resorption. The control group exhibited a complete bone fill and bone formation rate which was more than that in the experimental groups.

Conclusion. The findings of this study indicate that using of DBBM with and without PRGF might successfully maintain socket dimensions.
