Revitalizing the Smile: A Case Report on the Modified Apexification Procedure for Discolored Non-Vital Immature Teeth With Periapical Lesions.

Apexification is the process of forming mineralized tissue at the apical portion of a tooth with an incompletely formed root. Although various materials and techniques for the endodontic treatment of such teeth have been employed for some time, selecting the appropriate material remains challenging due to limited literature. This report presents a case that evaluates the efficacy of a modified apexification procedure using mineral trioxide aggregate (MTA), followed by a walking-bleach technique to address discoloration resulting from trauma to anterior teeth.

Comparative Assessment of the Antimicrobial Efficacy of Photoactivated Disinfection Employing Distinct Photosensitizers: A Morphological Analysis Using Scanning Electron Microscopy and Confocal Laser Scanning Microscopy.

Background The complex morphology of the root canal system and bacterial infiltration to greater depths precludes complete debridement by mechanical preparation alone. Despite promising characteristics of photodynamic inactivation (PDI) and different photosensitizers (PSs), there has been limited research on the antibacterial efficacy of chitosan (CS)-based PS combinations for root canal disinfection. We aimed to evaluate and compare the antimicrobial efficacy of photoactivated disinfection (PAD) using two different PSs as an adjunct to final irrigation in root canal treatment.

A Comparative Analysis of the Antimicrobial Efficacy of Nisin in Different Vehicles Against Enterococcus faecalis: An In Vitro Study.

Aim To evaluate and compare the antimicrobial efficacy of nisin in different carriers against . Materials and methods Test materials were divided into four groups of five samples each as follows: group 1 = nisin + 17% ethylenediaminetetraacetic acid (EDTA); group 2 = nisin + 2% chitosan; group 3 = nisin + 2% chlorhexidine; group 4 = nisin + distilled water (control). The antimicrobial effectiveness was assessed using the direct contact method, where a standardized suspension was applied to the test materials.

Platelet-Rich Fibrin: A Self-Derived Biomaterial for Surgical Treatment of a Periapical Lesion.

This case report explores the application of platelet-rich fibrin (PRF) as an autologous biomaterial in the surgical management of a periapical cyst in an 18-year-old female patient. The patient presented with pain, discoloration, and swelling in the maxillary left central incisor region, indicative of an asymptomatic periapical lesion associated with a history of trauma. Despite initial endodontic treatment with calcium hydroxide, the lesion persisted, necessitating surgical intervention.

Advanced Management of Open Apex Utilizing Platelet-Rich Fibrin and Bone Graft As Apical Barriers With Mineral Trioxide Aggregate (MTA) Obturation: A Detailed Case Report.

Management of open apex cases in endodontics poses a significant challenge, especially in immature teeth with necrotic pulps. Traditional apexification techniques have been the mainstay of treatment, aiming to induce the formation of a calcific barrier at the root apex. However, newer approaches incorporating biological materials such as platelet-rich fibrin (PRF) and demineralized bone matrix (DMBM) have emerged as promising alternatives.
