通过病变灭菌和组织修复评估坏死原代磨牙管理中不同药物的评估
基于纳米的药物与双重抗生素糊管理非重要原发性磨牙:一项随机临床试验和维特罗研究
Management of non-vital primary molars is challenging due to the natural anatomy of primary teeth, patients' young age, and their behavior toward dental treatment. A simple and effective technique such as Lesion Sterilization and Tissue Repair offers a solution to cases with poor prognosis; however, the medicaments used in this technique have some limitations. This study will evaluate three different medicaments regarding the clinical success, radiographic success, and antibacterial activity.

详细说明
This randomized controlled trial will include 108 non-vital mandibular primary molars in children aged 4-8. Patients will be randomly allocated into three groups according to the studied medicaments as one positive control group and two experimental groups. The groups are as follows:
Group I (conventional double antibiotic paste) positive control group Group II (double antibiotic paste-loaded chitosan-coated silver nanoparticles) experimental group Group III (chitosan-coated silver nanoparticles) experimental group
The antibacterial activity of studied medicaments will be tested against Enterococcus Faecalis bacteria in planktonic and biofilm forms. Teeth will be evaluated clinically and radiographically to obtain baseline data. After local anesthesia administration and isolation of teeth, an access cavity will be performed, then the medicament will be placed over the floor of the pulp chamber according to the corresponding group. Afterwards, teeth will be filled with resin-modified zinc oxide and eugenol followed by stainless steel crowns. Blinded clinical evaluation will be done at baseline, 1, 6, and 12 months and blinded radiographic evaluation will be done at baseline, 6, and 12 months.
