Evaluation of hemosponge in promoting dental socket healing after 3rd mandibular premolar extraction in a feline model|
Tavakoli, Azin & Sagart, Alireza
Aim: To investigate the healing process following use of collagen sponges in the dental socket after
extraction. Wound complications during the study were also evaluated.
Methods: 32 cats were
included in this study. IV administration of the combination of diazepam (0.22 mg/kg) and ketamine
(10 mg/kg) was used to induce general anesthesia. Surgical extraction of both 3rd mandibular
premolars was performed. The open dental sockets were divided in two groups. In Group A, the
open dental socket on the left side was closed using 4-0 Monocryl in simple interrupted pattern. In
Group B, the right dental socket was filled with lyophilized hydrolyzed collagen and the buccal and
lingual flaps were sutured using 4-0 Monocryl and simple interrupted pattern. Meloxicam (0.2 mg/kg) was used to manage the post-extraction pain in all cats. Ampicilline 20 mg/kg was used as
prophylaxis. The wounds were observed during the study to evaluate any signs of inflammation
or dehiscence. Radiographs were taken to compare healing of the socket 3 weeks after the
procedure. A 1 mm biopsy punch sample was taken from sockets in all cats for comparison of the
healing in both groups.
Results: Hemorrhage occurred only in the sockets of Group A. Remission
of radiolucent area occurred in both groups. Mean score of inflammation was lower and mean
scores of fibrotic reaction and fibroplasia were higher in Group B (p<0.05).
Conclusions: Use of
hemosponge in alveolar socket may accelerate fibroplasia and formation of the connective tissue
and reduce inflammation after tooth extraction. Therefore, post-extraction use of the hemostatic
agent in the dental socket is recommended.
