Success of Lesion Sterilization and Tissue Repair Therapy
A Phase 4 study testing Lesion Sterilization and Tissue Repair Therapy and Different Antibiotic Combinations in people with Primary Teeth and Pulp Necrosis, run by Inonu University at 1 site in Turkey (Türkiye).
Trial summary
This study aimed to assess the clinical and radiographic success of lesion sterilization and tissue repair (LSTR) therapy with different antibiotic combinations, focusing on evaluating whether the alternative combination of clindamycin instead of minocycline is as effective as the standard 3Mix-MP formulation.

About this study
Official title: Evaluation of the Clinical and Radiographic Success of Different Antibiotic Combinations in Lesion Sterilization and Tissue Repair Therapy for Infected Primary Molar Teeth
This study aimed to assess the clinical and radiographic success of lesion sterilization and tissue repair (LSTR) therapy with different antibiotic combinations, focusing on evaluating whether the alternative combination of clindamycin instead of minocycline is as effective as the standard 3Mix-MP formulation.
Read the detailed description
All the clinical procedures were carried out by one clinician with 2 years of clinical experience in pediatric dentistry under rubber dam isolation and local anesthesia via mandibular nerve block. (Maxicaine Fort Ampoule, VEM, Turkiye). After the removal of carious tissues, an endodontic cavity was prepared, and infected coronal pulp tissue was removed up to the canal orifices via a sterile round steel bur. A sterile round steel bur was then used to prepare a medication cavity 2 mm deep and 1 mm wide. The root canals were not instrumented, and only the access cavity was irrigated with a 2.5% NaOCl solution. In cases where hemostasis could not be achieved, a sterile cotton pellet soaked in 5% NaOCl was placed in the pulp chamber and left for 1 minute. Once hemostasis was achieved, the endodontic cavity was dried using a sterile, dry cotton pellet. Pastes were then applied to the medication cavity and covered with a glass ionomer cement (Nova Glass II F, Imicryl, Turkiye) and a stainless steel crown (Kids Crown, Shinhung, Seoul, Korea) at the same visit. Clinical and radiographic evaluations were performed at 1, 3, 6, 9, and 12 months. During follow-up, the teeth were assessed on the basis of the following clinical criteria: pain, dentoalveolar abscess and/or fistula, and tooth loss. The radiographic criterion was periapical radiolucency.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Lesion Sterilization and Tissue Repair TherapyProcedure or surgery
LSTR treatment is a minimally invasive, cost-effective, and easy-to-apply procedure for necrotic primary teeth, with a focus on disinfection with an antibiotic mixture without the need for root canal instrumentation.

What is being measured
The primary outcome is the main question the study is designed to answer.
clinical success
clinical criteria: pain, dentoalveolar abscess and/or fistula, and tooth loss.
Measured: 12 months
radiographic success
radiographic criterion was periapical radiolucency.
Measured: 12 months
overall success
If at least one of the clinical findings was present, the treatment was considered unsuccessful. However, even if teeth fail radiographically, they are not classified as overall failure if no clinical signs are present.
Measured: 12 months

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
clinical success (time frame: 12 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2025; AzTrials last refreshed its copy on 7 Nov 2026.
