Dental Pulp Necrosis
About this trial
This is an interventional treatment trial for Dental Pulp Necrosis focused on measuring Primary teeth, Dental Pulp Necrosis, Root Canal Obturation
Eligibility Criteria
Inclusion Criteria:
- Lower primary molars with clinical and / or radiographic history of pulp necrosis.
- Crown with sufficient dental structure to be restored with stainless steel crown.
- Rhizolysis equal to or less than 1/3.
Exclusion Criteria:
- Teeth that present calcium metamorphosis.
- Pathological root resorption.
- Coronary destruction that makes it impossible for the tooth to be restored.
- You have been using antibiotics for the last three months.

Group 1
Group 2
In group 1, Pulp Therapy will be done with the CTZ paste (composed of 62.5 mg of chloramphenicol, 62.5 mg of tetracycline, 125 mg of zinc oxide) will be manipulate with 0.1ml of eugenol in a sterile glass plate with flexible metal spatula at the time of use and will be taken at the tip of a number 5 exploratory probe and dispensed at the entrances of the root canals where it will be accommodated with light pressure of sterile cotton balls. The CTZ paste will be protected with a thin layer of gutta-percha, previously heated in an alcohol lamp and placed in a thin layer on the CTZ pulp. The gutta-percha blade will be condensed with medium size amalgam presser and has the objective of physically isolating the CTZ paste from the restorative material.
In Group 2, Pulp Therapy will be done with ZOE paste. The mechanical preparation of the root canals with 2% chlorhexidine solution and first-series K files will be performed. The instrumentation limit shall be 1 mm short of the radiographic apex. After finishing the chemical-mechanical preparation, drying of the root canals with sterile absorbent paper cones and ZOE paste insertion with K files will be performed. The zinc oxide of the ZOE paste will be supplied in 250mg capsules and handled with 0.1ml eugenol in a sterile glass plate with metal spatula at the time of use. The protection of the ZOE paste will follow the same sequence as the CTZ paste.
