The cation of the title compound, C(14)H(15)N(2)O(2) (+)·Cl(-), comprises two almost ideally planar systems, 3-nitro-phenyl (r.m.s. deviation = 0.0117 Å) and 4-methyl-phenyl (r.m.s. deviation = 0.238 Å), separated by the central C-N bond, and with their mean planes inclined to one another by 61.36 (5)°. In the crystal, hydrogen-bonded chains running along [001] are generated by connecting neighbouring mol-ecules via N-H⋯Cl hydrogen bonds and consolidated by C-H⋯Cl and C-H⋯O inter-actions. Within these chains, fused R(2) (1)(6) and R(3) (2)(10) ring motifs are formed. Parallel chains are further linked into a two-dimensional network parallel to (100) via C-H⋯O inter-actions.

Clinical Relevance: Horizontal rectus muscle surgeries may cause changes in corneal and anterior segment parameters. Corneal topography is an important device for identifying these alterations.
Background: The aim of this work is to evaluate the effects of horizontal rectus muscle surgeries on corneal topography, anterior chamber parameters and corneal wavefront aberrations.

Aim And Background: Glass ionomer cement (GIC) serves as a widely used restorative dental material, known for its direct bonding to tooth structures and fluoride-releasing properties. This study aims to investigate the enhancement of GIC through the incorporation of a green-mediated nanocomposite comprising chitosan, titanium, zirconium, and hydroxyapatite, with a focus on evaluating the wear resistance of the modified GIC.
Materials And Methods: A one-pot synthesis technique was utilized to prepare a green-mediated nanocomposite incorporating chitosan, titanium, zirconium, and hydroxyapatite nanoparticles.

Background And Objectives: The present study aims to assess and compare the accuracy of post-space impressions captured by three different intraoral scanners (IOS) using various canal diameters.
Methods: Three extracted natural maxillary central incisors were selected and prepared for a 1 mm wide margin and a 3 mm ferrule. All steps required for the endodontic procedure were performed, and the post space was prepared using post drills.

Objectives: To evaluate the accuracy (trueness and precision) of liquid crystal display (LCD)-printed orthognathic surgical splints under two different post-processing conditions-rinsing solvent and post-polymerization time.
Materials And Methods: An LCD 3D printer was used to create 48 surgical splints using the same reference standard tessellation language (STL) files. They were randomly assigned to two experimental studies.

Objective: This study aimed to compare the manufacturing accuracy of different printing techniques - Stereolithography (SLA), Digital Light Processing (DLP), and PolyJet-using digital dental models.
Methods: The study included cast models of 30 patients aged between 12 and 20 years. The selected models were scanned using an intraoral scanner, and surface topography format files were obtained.
