Internal resorption is a rare lesion in permanent teeth. Managing perforating internal resorption is a great challenge for dentists. This report presents a successful surgical treatment of a maxillary central incisor that had extensive root perforation due to internal resorption. After unsuccessful nonsurgical approach, during surgical intervention apical part of the resorption defect was removed and the coronal part was filled with mineral trioxide aggregate. Three years later the tooth was symptom free with normal mobility and pocket depth despite unfavorable crown-to-root ratio. This case report have shown that surgical intervention and using mineral trioxide aggregate as root canal filling material in a tooth with extensive internal resorption and unfavorable crown-to-root ratio can be considered as a treatment option.

Pulp chamber and root canal obliteration (PCO/RCO) presents a challenge for clinicians when nonsurgical endodontic treatment is indicated. Guided endodontics (GE) aims to precisely locate the root canal (RC) system while preserving as much pericervical dentin as possible. GE involves integrating cone-beam computed tomography (CBCT) of the affected tooth with a digital impression of the maxillary/mandibular arch, allowing for careful planning of the drilling path to the RC system through a three-dimensional (3D) static guide.

Introduction: Septic arthritis, primarily caused by (), is a severe joint infection that leads to joint and bone damage. lipoproteins (LPPs) bind to Toll-like Receptor 2 (TLR2), inducing arthritis and localized bone loss. Aging affects TLR2 immune response to pathogens.

Background: Anterior disc displacement (ADD) is the most common type of temporomandibular joint (TMJ) internal derangement and may lead to condylar resorption (CR) during the adolescence period, but the specific malocclusion associated with ADD and CR remains unclear.
Objective: This study aimed to investigate the malocclusion associated with TMJ ADD and CR in adolescents.
Methods: This cross-sectional study included a clinical examination of adolescent patients aged 11-19 years.

Mechanical unloading causes bone loss, but it remains unclear whether disuse-induced changes to bone microstructure are permanent or can be recovered upon reloading. We examined bone loss and recovery in 17 astronauts using time-lapsed high-resolution peripheral quantitative computed tomography and biochemical markers to determine whether disuse-induced changes are permanent. During 6 months in microgravity, resorption was threefold higher than formation.

Objective: To evaluate the effect of a newly developed MTA-based material and two antibacterial-enhanced MTAs as pulp capping materials in immature permanent dental elements underwent full pulpotomy.
Methods: The present animal study included 20 Wistar albino rats that, after full pulpotomy, were randomly divided into 4 groups receiving different MTA formulations as pulp capping materials: conventional MTA, Tricalcium aluminate (TCA)- free MTA, and MTA enhanced with metronidazole or doxycycline. Histopathological assessments were carried out at 7- and 28-days post-treatment to evaluate dentinal bridge formation, inflammatory reactions, pulp tissue necrosis and internal resorption.
