Triple Antibiotic Paste vs Simvastatin for Lesion Sterilization and Tissue Repair in Primary Molars.

This randomized, double-blinded, parallel-controlled clinical trial aims to compare the effectiveness of Triple Antibiotic Paste (TAP) and Simvastatin in Lesion Sterilization and Tissue Repair (LSTR) of primary molars with pulp necrosis. A total of 60 children (aged 5-8 years) with non-vital primary molars will be recruited from the Department of Operative Dentistry and Endodontics, Dow International Dental College, Karachi. Participants will be randomly assigned to one of two groups: Group 1 (Control): LSTR using Triple Antibiotic Paste (Ciprofloxacin + Metronidazole + Cefixime). Group 2 (Intervention): LSTR using Simvastatin paste. Both materials will be placed after non-instrumentation cleaning and sealed with glass ionomer cement, followed by stainless steel crown placement. Patients will be evaluated clinically and radiographically at 1, 2, and 3 months post-treatment. Primary outcomes include clinical success (absence of pain, swelling, or sinus tract) and radiographic success (reduction or absence of periapical radiolucency). Data will be analyzed using SPSS v26, with chi-square and t-tests applied as appropriate; p \< 0.05 will be considered significant. This study seeks to determine whether Simvastatin, owing to its antibacterial, anti-inflammatory, and regenerative properties, can serve as a viable alternative to antibiotic-based LSTR in managing necrotic primary teeth.

Evaluation of Regenerative Endodontic Treatment for Immature Teeth

The goal of this clinical trial is to evaluate if regenerative endodontic treatment using two different forms of demineralized dentin matrix (DDM) can effectively treat immature permanent single-rooted teeth compared to treatment using RetroMTA in patients aged 9 to 15 years. The main questions it aims to answer are: Does the use of DDM improve clinical and radiographic outcomes such as root length, dentinal wall thickness, and apex closure? Is DDM a viable bioactive alternative to RetroMTA as a coronal sealing material in regenerative endodontic procedures? Researchers will compare three groups: one using RetroMTA, one using a DDM-TheraCal LC mixture, and one using TDM-Hydrogel, to see if these materials differ in their effects on regenerative outcomes. Participants will: Undergo two treatment visits including canal disinfection, induction of bleeding to form a blood clot scaffold, Receive placement of one of the study materials over the blood clot as a coronal barrier, Have clinical examinations and CBCT imaging at baseline and multiple follow-ups up to 12 months to assess treatment success through signs, symptoms, and radiographic changes.

Bite Force Measurements

ABSTRACT: Acute dental pain from untreated decay often drives patients to emergency rooms (ERs), where the lack of definitive dental treatment results in nearly 75% of these patients receiving analgesics, predominantly opioids. Addressing the need for non-opioid pain alternatives is crucial. Emerging evidence suggests that dental pain from pulpal and periodontal conditions (affecting the tooth's nerve and surrounding tissues) involves neuropathic mechanisms, such as mechanical allodynia (MA) and central sensitization (CS). These mechanisms can amplify pain perception, causing typically non-painful actions, like chewing, to become painful and resulting in hypersensitivity extending beyond the affected tooth. Reliably identifying these mechanisms with quantitative measures can support improved pain assessment and targeted non-opioid treatment. This minimally invasive prospective cohort study will use the FDA-approved Innobyte® device, a precise bite-force measurement tool, to evaluate periodontal health and to quantify mechanical pain thresholds in patients requiring endodontic treatment (root canal therapy).

Comparison of LSTR and Pulpectomy in Primary Molars of Pediatric Patients (LSTR-PULP)

This study aims to compare the effectiveness of Lesion Sterilization and Tissue Repair (LSTR) with conventional pulpectomy in treating pulpal lesions in primary molars of pediatric patients aged 4 to 10 years. LSTR is a minimally invasive method that uses antibiotic paste to disinfect infected tissue without full canal instrumentation. Children participating in this study will receive either the LSTR technique or standard pulpectomy, and the clinical and radiographic success of both treatments will be evaluated over a 12-month period. The goal is to determine whether LSTR is a safe and effective alternative to pulpectomy in primary teeth.
