Lesion Sterilization Tissue Repair and Conventional Pulpectomy in Primary Molars

The aim of this study was to compare the clinical and radiographic success of conventional root canal treatment and lesion sterilisation tissue repair methods in deciduous molars with necrotic or irreversible pulpitis.

Inclusion Criteria: * The participant is between the ages of 3 and 8 years. * The participant and their parent(s) have signed informed consent forms agreeing to participate in the study. * The patient is systemically healthy. * The patient's cooperation level is sufficient for performing the procedures. * No history of allergic reactions to the materials and substances to be used. * Mandibular primary molars diagnosed with pulp necrosis or irreversible pulpitis. * Presence of endodontic-origin gingival abscess or fistula in the involved teeth. * History of spontaneous pain. * Presence of radiolucency in the furcation or periapical region, not exceeding one-third of the affected area. * Presence of deep dentin caries causing pulp exposure. * Presence of mobility at level 0 or 1 according to Miller's classification (non-pathologic). * The tooth meets the criteria for restorability. * Root resorption does not exceed more than four-fifths of the root. * The tooth meets the criteria for isolation. Exclusion Criteria: * The participant is not between the ages of 3 and 8 years. * The participant and/or their parent(s) have not agreed to participate in the study or have not signed the informed consent forms. * The patient has a systemic disease. * The patient's cooperation level is insufficient to perform the procedures. * The patient has a history of allergic reactions to the materials and substances to be used. * Teeth with external or internal root resorption. * Mechanical or carious perforation of the pulp floor in the affected teeth. * Radiolucency and bone destruction in the furcation or periapical region exceeding one-third of the affected area. * Presence of caries that does not cause pulp exposure. * Pathological mobility according to Miller's classification (\>1 score). * The tooth does not meet the criteria for restorability. * Root resorption exceeds more than four-fifths of the root. * The tooth does not meet the criteria for isolation.
