Abstract Statement of Problem Despite the growing utilization of direct intraoral scanners (IOSs) in dentistry, there is a scarcity of research investigating their accuracy, specifically in post and core. Few studies have conducted comprehensive three-dimensional assessments and comparisons of IOSs with the conventional impression technique, particularly...

Abstract Objectives To provide a 3-year follow-up of previously treated patients to assess and compare the periodontal responses and clinical performance of proximal subgingival open sandwich restorations. Materials and Methods Ninety-five adults participated in the study, with a combined total of 120 compound Class II cavities. These cavities had...

Abstract Purpose The purpose of the present clinical study was to compare the Ricketts and Steiner cephalometric analysis obtained by two experienced orthodontists and artificial intelligence (AI)-based software program and measure the orthodontist variability. Materials and Methods A total of 50 lateral cephalometric radiographs from 50 patients...

Abstract The reverse impression method involves the extraoral digitalization of the interim implant-supported prostheses and intraoral digitalization of antagonist arch and maxillomandibular relationship. This technique allows the fabrication of implant-supported prostheses by using a complete-digital workflow. The scan analogs make the reverse impression...

Abstract Objective The purpose of this in vitro study was to evaluate the effect of potassium aluminum sulfate (alum) application on the stainability and translucency of computer-aided design and computer-aided manufacturing (CAD-CAM) materials after coffee thermocycling (CTC). Materials and Methods Disk-shaped specimens (Ø10 × 1 mm; N = 200) were...

Abstract Objectives Determine visual 50:50% color difference acceptability thresholds (AT) for regions of the dental color space with varying chromaticity. Methods A 40-observer panel belonging to two different groups (dentists and laypersons) evaluated 144 dental resin composites pairs (divided in three different sets of 48 pairs according to chroma...
