Plain English summary of protocol
Background and study aims
The aim of this study is to evaluate the success rate of non-instrumentation endodontic treatment using a modified antibiotic paste of cefexime, ciprofloxacin and metronidazole with simvastatin (an anti-inflammatory, bone regeneration drug) on necrotic (dead) primary molars compared to traditional pulpectomy (complete removal of the pulp of the teeth).
Who can participate?
Children aged 4-8 years old with necrotic primary second lower molars
What does the study involve?
Participants will be randomly divided into two groups to be treated with antibiotics in non-instrumentation endodontic treatment or conventional root canal treatment. All the teeth will be evaluated after 1, 3, 6, and 12 months clinically and 3, 6, and 12 months radiologically (x-ray).
What are the possible benefits and risks of participating?
Because of the complexity of the root canal system in primary molars, long or multiple visits are needed to complete pulpectomy treatment, especially with non-cooperative children. Non-instrumentation endodontic treatment seems to be a good alternative choice to traditional pulpectomy as it's an easier and less time-consuming treatment.

| Scientific title | Clinical and radiological evaluation of modified triple antibiotic paste and simvastatin in non-instrumentation endodontic treatment of necrotic mandibular primary molars: a randomised controlled clinical trial |
| Study acronym | 3Mixtatin in NIET |
| Study objectives | This study is designed to assess the hypothesis that non-instrumentation endodontic treatment with 3mixtatn can be a good alternative treatment to traditional pulpectomy of necrotic primary molars. |

| Health condition(s) or problem(s) studied | Necrotic primary molars |
| Intervention | Forty-two necrotic mandibular primary second molars from healthy children aged 4-8 years will be randomly divided into two groups using http://www.randomization.com: Group A: teeth will be treated with 3mixtatin in non-instrumentation endodontic treatment Group B: teeth will be treated with conventional root canal treatment After local anesthesia using mepivicaine hydrochloride 3%, each tooth will be isolated using the rubber dam. The carious lesions will be removed and the access cavity will be prepared with a bur in a high-speed handpiece. In group A the canal orifices will be enlarged with a round bur (1 mm diameter and 2 mm depth). The pulp chamber and the canal orifices will be irrigated with 17% EDTA to remove the smear layer and the dentin permeability increased with chemical solutions and then with physiological serum, followed by irrigation with 10 ml 5.25% sodium hypochlorite to remove the necrotic tissues, then irrigated with physiological serum and finally with chlorhexidine gluconate 0.2%. This irrigation protocol will be administered in both two groups. 3Mixtatin preparation: The three commercially available antibiotics metronidazole, cefixime and ciprofloxacin will be mixed in a ratio of 1:1:1 with 2 mg of simvastatin after removing the coating materials and pulverized by porcelain mortars and pestles. The 3Mixtatin will be mixed with propylene glycol to obtain a creamy mix and placed over the canal orifices and the pulpal floor. The tooth will be sealed with a glass ionomer cement and then restored with a stainless steel crown. In group B conventional root canal treatment will be done using k-files and h-files and using the previously mentioned irrigation protocol in group A. The root canals will be dried with paper points and obturate with zinc oxide eugenol paste using a Lentulo spiral in a low-speed handpiece. The tooth will be sealed with a glass ionomer cement and then restored with a stainless steel crown. All procedures will be administered by a pediatric dentist. All the teeth will be evaluated after 1, 3, 6, and 12 months clinically and 3, 6, and 12 months radiologically. |
