Detailed Description
This study was designed as multicenter randomized control clinical trial. The present trial was conduced according to CONSORT statement for improving the quality of reports of parallel-group randomized trials .
The intra-bony defects of subjects allocated in test group were treated with a combination of minimally invasive surgical technique (MIST) and enamel matrix derivative(EMD), while the intra-bony defects of control group were treated using a combination of conventional open flap debridement with papilla preservation (COFD+PP) and EMD.
Primary outcome
The primary outcome was based on Clinical attachment level gain( CAL gain)
Null hypothesis
Statistically significant different in terms of CAL gain will be recorded between test and control procedures.
Sample Size Calculation
The investigators are planning a study of a continuous response variable from independent control and experimental subjects with 1 control per experimental subject. In a previous study the response within each subject group was normally distributed with standard deviation 0,92. If the true difference in the experimental and control means is 0,97, we will need to study 20 experimental subjects and 20 control subjects to be able to reject the null hypothesis that the population means of the experimental and control groups are equal with probability (power) 0,8. The Type I error probability associated with this test of this null hypothesis is 0,05. Twenty-six patients were enrolled in the study and allocated in test or control group. In each patients 1 intra-bony defect was considered.
Randomization
The patients were randomly assigned to one of the two experimental procedures. The allocation was carried out using a commercially available computer software package. Treatment allocation was performed at time of surgery by opening an envelope containing the information test (i.e.EMD + MIST) or control (i.e.EMD + COFD+PP) procedure, respectively.

Intervention / Treatment |
---|---|
EXPERIMENTAL: Minimally invasive surgical technique
The intra-bony defects of subjects allocated in test group were treated with a combination of minimally invasive surgical technique (MIST) and enamel matrix derivative( EMD).
|
After local anesthesia , for the sites of test group , a minimally invasive surgical technique (MIST) will be performed.
The defects associated inter-dental papilla will be surgically approached with a diagonal incision following the pattern of the simplified papilla preservation flap.
Flap elevation was to the buccal and oral aspect in the interdental space, An enamel matrix derivative (EMD) was applied into the defect.f
A primary closure of the interdental papillae will be achieved using a 5-0 monofilament non resorbable suturing material.
