Abstract: Background: Preservation of the original root canal anatomy during biomechanical preparation is essential for successful endodontic treatment. Canal transportation and centering ability are important parameters used to evaluate the shaping performance of endodontic instruments, particularly in curved root canals. Advances in nickel-titanium (NiTi) metallurgy and instrument kinematics have led to the development of systems designed to improve canal centering and minimize procedural errors.
Aim: To compare the canal transportation.....

To determine the prevalence of urolithiasis and assess hydration status among adults.
2.

Abstract: Background: Congenital and early-onset hearing impairment is one of the more easily overlooked disabilities in the neonatal period largely because affected infants look and behave at least outwardly much like their normally hearing peers. Neonates who pass through a difficult perinatal course prematurity, low birth weight, perinatal asphyxia, Hyperbilirubinemia or a stay in the neonatal intensive care unit carry a substantially higher likelihood of cochlear or retro-cochlear dysfunction than the general newborn population which is precisely targeted screening in this subgroup deserves close attention.
Objective: To evaluate...

Abstract: Background: Chelating irrigants facilitate smear-layer removal but may alter the mineral phase of root dentin. Etidronic acid (HEDP) permits continuous chelation with sodium hypochlorite (NaOCl), while diode-laser activation may modify irrigant–dentin interaction. Aim: To compare the elemental surface composition of apical root dentin after 17% ethylenediaminetetraacetic acid (EDTA) or HEDP used with or without 980-nm diode-laser activation. Materials......

Abstract: Background: Pericoronitis involving the operculum of a partially erupted mandibular third molar is a common indication for minor oral surgery. Operculectomy performed using conventional methods may be associated with bleeding and postoperative discomfort. Soft-tissue lasers provide potential advantages through precise tissue ablation and hemostasis. This case series compares the clinical outcomes of carbon dioxide (CO₂) and diode laser-assisted operculectomy in patients with pericoronitis.

Abstract: Background: Rehabilitation of severely resorbed edentulous arches is challenging because of inadequate bone volume, poor denture stability, and compromised function. The All-on-Four® concept provides an alternative approach for fixed full-arch rehabilitation by strategically positioning four implants to maximize available bone and reduce the need for extensive augmentation. Digital technologies such as cone-beam computed tomography (CBCT), virtual......
