In Araújo M, Linder E, Lindhe J Effect of a xenograft on early bone formation in extraction sockets: an experimental study in dog. Clin Oral Implants Res. 2009 Jan; 20(1):1-6. What was found after placement of a Bio Oss graft into sockets of fresh extraction sites?
The placement of Bio-Oss Collagen in the fresh extraction wound obviously delayed socket healing.Thus, after 2 weeks of tissue repair, only minute amounts of newly formed bone occurred in the apical and lateral borders of the grafted sockets, while large amounts of woven bone had formed in most parts of the non-grafted sites

Effect of calcium hydroxide-based materials on periapical tissue healing and orthodontic root resorption of endodontically treated teeth in dogs.
Dent Traumatol. 2009 Apr; 25(2):213-218.
What was the study evaluating? What was the ultimate finding?
This study evaluated periapical tissue healing and orthodontic root resorption of endodontically treated teeth sealed with calcium hydroxide in dogs.
Under the tested conditions, Ca(OH)2-based materials had a favorable action on periapical tissue healing and repair of orthodontic root resorption in endodontically treated dogs’ teeth.

Dimensional changes of the ridge contour after socket
preservation and buccal overbuilding: an animal study.
J Clin Periodontol. 2009 May; 36(5):442-448.
What was the result of buccal overbuilding after tooth extraction?
Overbuilding the buccal aspect in combination with socket preservation is not a suitable technique to compensate for the alterations after tooth extraction.

Outcome of root canal treatment in dogs determined by periapical
radiography and cone-beam computed tomography scans.
J Endod. 2009 May; 35(5):723-726
How were the animald divided into groups?
Ninety-six roots of dogs’ teeth were used to form four groups (n= 24). In group 1, root canal treatments were performed in healthy teeth. Root canals in groups 2 through 4 were infected until apical perio- dontitis (AP) was radiographically confirmed. Roots with AP were treated by one-visit therapy in group 2, by two-visit therapy in group 3, and left untreated in group 4.

Outcome of root canal treatment in dogs determined by periapical
radiography and cone-beam computed tomography scans.
J Endod. 2009 May; 35(5):723-726
What was the purpose of the study?
The purpose was to compare the treatment outcome after performing root canal therapy in dogs as determined by PR and cone-beam computed tomography (CBCT) scans

J Endod. 2009 May; 35(5):723-726
What was the difference between the success of PR versus CBCT in detecting periapical pathology?
No AP lesions were detected with PRs at day 14 after root canal infection and 47% could be detected at day 21, whereas CBCT evaluation detected AP in 33% at day 14 and 83% at day 21

What other significnat finding was made?
Unfavorable outcomes determined by CBCT occurred more frequently after one-visit therapy compared with two-visit therapy.
