Orthograde Endodontic Retreatment Following Apicoectomy and Resorption of Extruded MTA—A Case Report With 8‐Year Follow‐Up

Clinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT Orthograde retreatment following unsuccessful apicoectomy is a valid treatment option instead of surgical retreatment. This case report details the successful orthograde retreatment of a 34‐year‐old female patient with persistent symptoms following prior apicoectomy without retrofilling materials and conventional root canal treatment.

Management of Oehler's Type II Dens Invaginatus in a Maxillary Lateral Incisor With Asymptomatic Periapical Periodontitis: A Case Report

Clinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT Dens invaginatus (DI), also known as dens in dente, is a rare developmental anomaly where the enamel organ folds into the dental papilla, resulting in complex anatomical structures. This anomaly predisposes teeth to early pulp involvement, periapical pathology, and treatment challenges, particularly in maxillary lateral incisors, which are ...

Effect of Different Adhesive Systems and Resin Cements on the Push‐Out Bond Strength of Fiber Reinforced Posts to Root Dentin

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 10, October 2025.
ABSTRACT Good bond strength between fiber‐reinforced posts (FRPs) and root dentin is essential for successful rehabilitation of endodontically treated teeth. 45 human premolar teeth were divided into three main groups (n = 15) based on bonding agent use: no bonding (control), light‐cured (LC), and dual‐cured (DC). Each group was further split by cement

Nonsurgical management of a large periapical lesion using aspiration in combination with a triple antibiotic paste and calcium hydroxide

Iranian Endodontic Journal, 2010
Persistent microorganisms in the root canal are known to cause endodontic treatments failure. Overextended gutta-percha can also act as a periradicular tissue irritant, leading to large periapical lesions.
