Objective: This article discusses the relationship between apical limit of root canal filling and success on endodontic treatment of a mandibular molar.
Study Design: A mandibular right first molar with vital pulp was endodontically treated, and 3 years later periapical lesions on mesial and distal roots were detected. The canals were retreated and obturated to the same levels as in the previous treatment.
Results: An 8-year radiographic follow-up showed repair of the periapical lesions on both roots.
Conclusions: Results suggest that the apical limit of obturation seems to have no influence in the repair of periapical tissues in mandibular molars.

One of the major issues encountered in patients undergoing evaluation for Transcatheter mitral valve replacement (TMVR) is the risk of Left ventricular outflow tract (LVOT) obstruction. LVOT obstruction is a catastrophic complication of TMVR, the result of displacement of the anterior mitral valve leaflet (AML) toward the interventricular septum. Several strategies to mitigate the risk of LVOT obstruction have been described and include percutaneous laceration of the anterior mitral leaflet (LAMPOON), alcohol septal ablation, trans-atrial leaflet modification (SITRAL) and Balloon Assisted Translocation of Mitral Anterior leaflet to prevent LVOT obstruction (BATMAN).

Methods to image the human RPE directly are limited, as it is only about 10 µm thick and situated between the photoreceptor outer segments and Bruch's membrane (BM).

The correlation between clinical, serological, and endoscopic findings and histological response after a gluten-free diet (GFD) is limited in adult celiac (CD) patients. This study aims to evaluate the effects of GFD on intraepithelial lymphocyte (IEL) localization by comparing the histopathological, clinical, serological, and endoscopic findings of adult CD patients. The patients (n = 131) were divided into three groups: those with good (CDgc) (n = 23) and poor (CDpc) (n = 21) GFD compliance and newly diagnosed ones (nCD) (n = 87).

Background: The purpose of the present case study is to describe the application of a modification of the Biologically-oriented Alveolar Ridge Preservation (BARP) principles in cases of peri-implant bone dehiscence (PIBD) due to a compromised alveolus at immediate implant placement (IIP).
Methods: The technique is based on the stratification of three layers: a deep layer with a collagen sponge (CS) in the apical part of the alveolus (where the buccal bone plate was still present) to support the blood clot; a graft layer to correct the PIBD; and a superficial collagen layer to cover the graft thus providing space and enhancing clot/graft stability. Healing was obtained by primary closure.

Background/purpose: The increasing importance of computer assisted implant surgery (CAIS) in the practice of implant dentistry calls for adequate education and training of clinicians. However, limited evidence exists to support optimal educational strategies and best practices. This study aimed to investigate the effectiveness of distributed training with dynamic CAIS (d-CAIS) on the precision of freehand implant placement by inexperienced operators.
