Comparative Evaluation of Microleakage in Class V Cavities Restored with Newer Bioactive Restorative Materials: Activa Bioactive Restorative and Activa Pronto.
Int J Clin Pediatr Dent
November 2024
Private Practitioner, Bengaluru, Karnataka, India.
Aim: To compare the microleakage in class V cavities restored with Activa Bioactive Restorative, Activa Pronto, and nanohybrid composite.
Materials And Methods: Standardized class V cavity preparations (mesiodistal: 3 mm; occlusocervical: 2 mm; axial depth: 1 mm) were made on the buccal surface of 60 extracted intact maxillary premolar teeth. The preparations were divided into three experimental groups ( = 20) depending on the restorative material used.
Student's perception of hybrid team-based and case-based learning in undergraduate endodontics education.

Conservative Dentistry Unit, School of Dental Sciences, Universiti Sains Malaysia, Health Campus, Kubang Kerian, Kelantan, 16150, Malaysia.
Background: Limited studies have explored the use of the hybrid approach combining team-based learning (TBL) and case-based learning (CBL) in dental education. This study evaluates how students perceive the hybrid TBL-CBL approach to learning endodontics and determines whether gender and ethnicity impact students' perceptions.
Methods: The final-year undergraduate Bachelor of Dental Surgery (BDS) students were invited to participate in a hybrid TBL-CBL session.

Center of Stomatology, Affiliated Hospital of Hangzhou Normal University, Hangzhou, China.
Purpose: We aimed to analyze the influence of different designs (inlay, onlay, and crown) on stress distribution and crack propagation in an endodontically treated cracked premolar.
Methods: Three-dimensional (3D) finite element analysis (FEA) was employed to model an endodontically treated cracked premolar with three different restorations (inlay, onlay, and crown). Six types of loadings (vertical loading of 600 N; hot thermal-600 N vertical coupling loading; cold thermal-600 N vertical coupling loading; oblique loading of 200 N; hot thermal-200 N oblique coupling loading; cold thermal-200 N oblique coupling loading) were applied to simulate the hot and cold food/beverages intake.
Fracture resistance and behavior of endodontically treated maxillary premolars with varying ferrule heights and post numbers: A laboratory study.

Department of Restorative Dental Science, College of Dentistry, University of Ha'il, Ha'il, Saudi Arabia.
Purpose: To investigate how varying ferrule heights and the number of glass fiber posts affect fracture resistance and behavior of endodontically treated maxillary first premolars with substantial loss of tooth structure.
Materials And Methods: Twenty-four extracted endodontically treated human maxillary first premolars were divided into three groups (n = 8) based on ferrule height and post number. The groups were as follows: premolars of 2 mm ferrule height that were restored with single posts (control group), premolars of 0.
An comparison of the fracture resistance of MOD inlay restorations using different lithium disilicates.

Department of Conservative Dentistry and Endodontics, Priyadarshini Dental College and Hospital, Pandur, Tamil Nadu, India.
Objective: The objective of this study was to evaluate and compare the fracture resistance of MOD inlay preparations restored with two different lithium disilicate glass ceramics.
Materials And Methods: Standardized MOD inlay cavities were prepared on 64 human permanent premolar teeth and divided into two groups to be restored with lithium disilicate glass-ceramic materials, i.e.
