Protocol summary

Study aim
Clinical and radiographic evaluation of chitosan particles in treatment of periodontal intra bony defect
Design
clinical trial - with two test and one control group -double blind - randomized
Settings and conduct
Surgeries are done in periodontology department of Babol dental faculty. Patients don't know that involve in which group. The flap is set to "full thickness" then scaling & root planning is performed. In test groups in three-wall bone lesions, chitosan is placed in low or high molecular weight. Chitosan powder is mixed with some serum and placed in the bone lesion. Then, in each group, place the "Cenomembrane" membrane on the lumbar lesion and suture.
Participants/Inclusion and exclusion criteria
The entry requirements were presence of 3-walled intrabony defects in buccal or lingual sides of upper or lower first or second premolar or molars. The exclusion criteria were suffering from any kind of systemic disorders; a need for prophylactic antibiotics to prevent bacterial endocarditis; taking any drugs interfering with periodontal wound healing; smokers; presence of any periodontal surgery contraindications; teeth with anatomical complications such as cervical enamel projections; bifurcation ridge; accessory canal and concavity; presence of hemiseptal bony defects; presence of caries in the root of teeth adjacent to the intrabony defect and last but not least uncooperative patients
Intervention groups
People are divided into 3 groups. First, the chitosan test was done by the Acros Inc with high molecular weight (MW800000-600000) in intrabony defects during flap. Second, the chitosan test was done by the Acros Inc with low molecular weight (MW300000-100000) and in the control group the flap surgery is only done. The groups are matched with sex and place of the lesions.
Main outcome variables
Clinical attachment level - Probing pocket depth - Radiographic Defect Depth

Randomization (investigator's opinion)
Randomized
Randomization description
The randomization scheme was 1:1:1 (2cases groups and 1 control group). Randomization was stratified by clinical trial site. The unblinded trial statistician generated randomization sequences (block randomization with block size of eight) and the unblinded clinical trial staff assigned each participant to a treatment group.
Blinding (investigator's opinion)
Double blinded
Blinding description
Patients do not aware of treatment group which they included The evaluater is different from surger and she is blind.
