Diphosphonates reduce the rate of bone turnover. They have additional pharmacological properties improving adjuvant arthritis in rats and lowering ESR in this condition. We have evaluated etidronate disodium, a diphosphonate commonly prescribed in the United Kingdom for Paget's disease in patients with rheumatoid arthritis. Apart from an early improvement in articular index, perhaps reflecting anti-inflammatory activity, no significant change occurred in clinical variables or in laboratory indices of 'secondline' action at a dose of 5 mg/kg/day.

Objectives: This study evaluates the effect of different irrigation solutions for postoperative pain in the regenerative endodontic treatments (RET) of necrotic teeth with open apex.
Materials And Methods: This study included necrotic, deeply carious lower molars of 42 patients. Access cavities of the teeth were opened and working lengths were measured at the first visit.

Geranylgeranyl pyrophosphate synthase (GGPPS), a key enzyme in protein prenylation, plays a critical role in cellular signal transduction and is a promising target for cancer therapy. However, the enzyme's native hexameric quaternary structure presents challenges for crystallographic studies. The primary objective of this study was to engineer dimeric forms of human GGPPS to facilitate high-resolution crystallographic analysis of its ligand binding interactions.

Laser-activated irrigation (LAI) of root canal systems depends on the generation of cavitation bubbles in the endodontic irrigant. Physical studies thus far focused on pulse energy, pulse length, frequency, and fiber tip shape, mostly in plain water. This study investigated the effect of endodontically relevant molecules (sodium hypochlorite (NaOCl), 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP), and their combination) in water on physical properties of the resulting solution, and their impact on primary cavitation bubble features.

Objective: The objective of the study was to investigate the influence of different irrigation protocols on the shear bond strength (SBS) of self-adhesive resin cement (SARC) on primed radicular dentin.
Methods: Radicular dentin slabs (N=58) were embedded in acrylic. Subsequently, they were polished and randomly assigned to five experimental groups (N=8-12) and one control group, CG (N=8).

Context: Effective endodontic treatment relies heavily on proper instrumentation, thorough disinfection, and precise three-dimensional obturation of the root canal system.
Aims: This study aims to evaluate and compare continuous chelation (etidronic acid and sodium hypochlorite [NaOCl]) and sequential chelation (citric acid and NaOCl) on the dentinal tubule penetration of bioceramic-based sealer (Bio-C)-A confocal laser scanning microscopic study.
Settings And Design: experimental study.
