Interventional
Description of intervention(s) / exposure
Second primary carious molars in children aged 5 - 8 years will be randomly divided into 2 groups:
Arm1: (0.2 g Chitosan)
Arm2: (0.2 g Mineral trioxide aggregate (MTA))
Each patient will receive vital pulpotomy in both second primary molars; in a split mouth design.
Intra- and extraoral examinations of patients will be performed before the treatment and their initial radiologic examinations will be performed.
Regional anesthesia will be performed, all cavity lesions will be removed, and an access cavity will be prepared under the isolation of rubber dam. A low-speed sterile round bur will be used for removing coronal pulp.
bleeding will be stopped using Sterile cotton pellets moistened with sterile saline. Then, pulp stumps will be covered with either chitosan films, or MTA.
All pulpotomized teeth will be restored with stainless steel crowns.
Interventions will be done by a pediatric dentistry resident and will take place in faculty of dentistry at Damascus university.
Clinical and radiographic evaluation will be performed after 3, 6 and 9 Months

Statistical methods / analysis
Sample size was calculate using g-power 3.1 software. The significance level was set at 0.05 and the power of the study was set to be 0.80.
Based on a Chi – Square test, it was estimate that 50 patients were required to demonstrate an effect size (0.4).
Sample size will be raised to 60 patients to avoid the negative effect of the possible drop rate.
Statistical analyses will be performed using the statistical software SPSS for Windows (version 25.0, SPSS Inc.,Chicago,IL,USA).

The chi-square and McNemar test will be performed. A P value <0.05 will be considered statistically significant.
