Overview

The aim of this study is to evaluate and compare the clinical effectiveness of zinc oxide-propolis mixture with triple antibiotic paste in LSTR as root canal filling material in necrotic primary molars.

The promising results of propolis as a natural antibiotic in previous in- vivo studies made it interesting to combine propolis to the golden standard zinc oxide eugenol as an intracanal medication in pulp affected primary molars and use this mix as a natural substitute to the modified triple antibiotic paste (m-TAP) and therefore overcoming the antibiotic bacterial resistance, allergy and developmental anomalies that might arise in permanent successor teeth from m-TAP usage.

Zinc oxide propolisCOMBINATION_PRODUCT

Propolis liquid (Brazilian Green Bee Propolis Liquid Extract, Uniflora®) and Zinc oxide powder will be mixed on a glass slab with the help of a stainless -steel spatula. • The mixing ratio of zinc oxide powder and Propolis liquid is 2:1 until a paste like consistency is reached.

Modified triple antibiotic pasteCOMBINATION_PRODUCT

Chemotherapeutic agents used are metronidazole tablets 500 mg (Flagyl®, Sanofi, Egypt), ciprofloxacin tablets 500 mg (Ciprofloxacin tablets USP 39®, European pharmaceuticals, Egypt,), and clindamycin capsules 300 mg(Dalacin C™ Pfizer, Egypt). * After the removal of enteric coating of tablets with the help of blade, the drugs are pulverized into fine powder using sterilized mortar and pestle. * The same amount of each powdered drug (1:1:1) is mixed to form m-TAP powder which is mixed with one part of propylene glycol (P) and the same volume of macrogol (M) to form a paste like consistency

Outcomes

Primary Outcomes

Postoperative pain

Binary outcome measured with direct questioning to the patient

Time frame: 1 year

Tenderness to percussion

(binary outcome measured by percussion test using back of the dental mirror

Time frame: 1 year

Swelling / sinus tract

binary outcome measured with visual examination of the patient examination of the patient

Time frame: 1 year

Mobility

(measured by mobility test) and according to Miller's Grades; reduction in grade of mobility from preoperative baseline was treated as success

Time frame: 1 year

Secondary Outcomes

Radiographic success

The amount of furcation / periapical radiolucency in comparison to preoperative remained static or decreased

Time frame: 6 months
