Overview
This study aims to evaluate and compare the clinical and radiographic outcomes of Lesion sterilization and tissue repair using zinc oxide/ 6-gingerol mix versus triple antibiotic paste in non-vital primary molars.
Description
In routine dental practice, clinicians often face challenges when primary teeth are affected by dental caries and periapical changes, which may exceed the limits of conventional endodontic treatments. Extraction often becomes the only viable option due to factors like extensive root resorption, poor bone support, and uncooperative young patients.
One promising less invasive method is Lesion Sterilization and Tissue Repair (LSTR), developed by Niigata University. This approach uses minimal instrumentation and applies an antibiotic mixture to disinfect the root canal and periapical lesions, often using a "three mix MP paste" of metronidazole, ciprofloxacin, and minocycline. Recently, clindamycin has been used instead of minocycline to avoid tooth discoloration.
Eligibility
Inclusion Criteria:
- Age from 4 to 8 years.
- Both sexes
- Children must have at least two restorable non-vital primary molars
- Periapical radiolucency.
- Pain on mastication.
- Pathological mobility.
- Internal or external root resorption.
- Furcation involvement should not extend to the developing tooth germ.
Exclusion Criteria:
- Presence of systemic diseases.
- Teeth with physiological mobility near exfoliation time.
- Teeth with vital pulp.
