Clinical internal and marginal fit of metal-ceramic fixed dental prostheses fabricated with selective laser melting and 3D-printed pattern casting using cobalt-chromium metal alloy.

Purpose: To evaluate the fit of metal-ceramic three-unit fixed dental prostheses (FDPs) fabricated using selective laser melting (SLM) and 3D-printed casting pattern (CP) and to compare the effect of tooth type and ceramic veneering on marginal and internal gaps.

Materials And Methods: Patients requiring posterior three-unit FDPs were selected. For each subject, two FDPs were fabricated using SLM and CP.

Mechanical properties of 3D-printed resin denture teeth: An in vitro study.

Purpose: The purpose of this study was to compare the wear, fracture strength, and mode of failure of various brands of 3D-printed resin denture teeth with prefabricated acrylic resin. Additionally, the study aimed to analyze the different modes of failure exhibited by these teeth.

Materials And Methods: The study utilized 90 3D-printed and 30 prefabricated, 3D-printed resin teeth from three brands: L = Optiprint Lumina, A = ASIGA DentaTooth, P = Power resins, along with prefabricated acrylic teeth from M = Major Super Lux.

Fracture strength of endocrown maxillary restorations using different preparation designs and materials.

Purpose: This study investigated the impact of preparation design and material types on fracture strength in maxillary premolars endocrowns after thermodynamic aging.

Materials And Methods: Eighty two-rooted maxillary premolar crowns underwent endodontic treatment (N = 80, n = 10). The teeth were categorized into ten groups (4-mm deep with no intracanal extension lithium disilicate glass ceramic & multilayer zirconia endocrowns (LE0 & ZE0); 4-mm deep with 4-mm intracanal extension in one canal (LE1 & ZE1); 4-mm deep with 2-mm intracanal extensions in both canals (LE2 & ZE2); flat overlays with no endocore (LO & ZO); glass fiber reinforced post & core and crown (LC & ZC)).

Blended learning in undergraduate dental education: a global pilot study.

Aims: To explore the global trends in blended learning in undergraduate dental education during the COVID pandemic and during the recovery phase by engaging with the students and faculty and evaluate the implications for dental education in the post-COVID era.

Methods: It was a pilot cross-sectional study which employed a convenience sampling technique to recruit representatives of dental faculty and undergraduate students in 80 dental institutions globally. A previously validated questionnaire consisting of a combination of closed and open-ended items was used for data collection.

Implications of resin-based composite (RBC) restoration on cuspal deflection and microleakage score in molar teeth: Placement protocol and restorative material.

Objective: To assess the cuspal deflection of standardised large mesio-occluso-distal (MOD) cavities in third molar teeth restored using conventional resin-based composite (RBC) or their bulk fill restorative counterparts compared with the unbound condition using a twin channel deflection measuring gauge. Following thermocycling, the cervical microleakage of the restored teeth was assessed to determine marginal integrity.

Methods: Standardised MOD cavities were prepared in forty-eight sound third molar teeth and randomly allocated to six groups.
