Exploring the Most Effective Apical Seal for Contemporary Bioceramic and Conventional Endodontic Sealers Using Three Obturation Techniques.

Despite a plethora of studies conducted to date, researchers continue to investigate the best sealer and obturation technique combinations. The aim of this study is to compare the apical seal provided by two bioceramic sealers (Endoseal and Endosequence) with that provided by a calcium hydroxide sealer (Sealapex), and to evaluate the effect of different obturation techniques (cold lateral condensation, continuous wave compaction and single cone) on the apical seal under a stereomicroscope. A total of 110 single-rooted mandibular premolar teeth were decoronated, cleaned and shaped using the Endosequence filing system to tip size 30/0.

Impact of antimicrobial photodynamic therapy on the bond-strength and penetration of endodontic sealers: A systematic review.

Background: Antimicrobial photodynamic therapy (aPDT) has been used for the disinfection of root canals. Studies have been carried out on its effect on the bond-strength and penetration of endodontic sealers. The aim of this systematic review is to critically analyze the literature and summarize the outcomes of these studies.

Comparative Study Assessing the Canal Cleanliness Using Automated Device and Conventional Syringe Needle for Root Canal Irrigation-An Ex-Vivo Study.

The success of endodontic treatment relies on both apical and coronal sealing. To achieve a good three-dimensional seal, the removal of the smear layer becomes mandatory. This study aims to assess the difference in debris accumulation and smear layer formation while using automated root canal irrigation and conventional syringe needle irrigation.

Gene and protein interaction network analysis in the epithelial-mesenchymal transition of Hertwig's Epithelial Root Sheath reveals periodontal regenerative drug targets - An in silico study.

Background And Aim: Hertwig's Εpithelial Root Sheath (HΕRS) has a major function in the developing tooth roots. Earlier research revealed that it undergoes epithelial-mesenchymal transition, a vital process for the morphogenesis and complete development of the tooth and its surrounding periodontium. Few studies have demonstrated the role of HERS in cementogenesis through ΕMΤ.

Effect of Different Intracanal Medicaments on the Viability and Survival of Dental Pulp Stem Cells.

Background: Stem cells play an important role in the success of regenerative endodontic procedures. They are affected by the presence of medicaments that are used before the induction of bleeding or the creation of a scaffold for endodontic regeneration. This study examines the effects of different intracanal medicaments on the viability and survival of dental pulp stem cells at different doses and over different exposure times.

Analysis of occupational stress, burnout, and job satisfaction among dental practitioners.

Background: Dental practitioners can be prone to stress because of the long working hours, high patient expectations, and work environment.

Objective: To investigate dimensions of occupational stress among dental practitioners leading to burnout and to model its causality with job satisfaction.

Methods: An analytical cross-sectional study was conducted for five months.

Radicular canal disinfection using photodynamic therapy and sodium hypochlorite following three chelating agents' green tea extract, grape extract, and EDTA on the push-out bond strength of epoxy resin-based sealer.

Aim: To appraise the efficacy of photodynamic therapy (PDT) and conventional regime (NaOCl) following three chelating agents ethylene diamine tetraacetic acid (EDTA), Green tea extract (GTE), grape extract (GE) on pushout bond strength (PBS) of epoxy resin-based sealer with root dentin.

Material And Methods: 60 single-rooted human teeth were prepped using a ProTaper system and cleansed using photodynamic therapy (PDT) and 5% NaOCl (n = 30 each). Samples in each group PDT and 5% NaOCl were further divided into 6 sub-group (n = 10) based on the chelating agents used: 17% EDTA, GTE, and GE.

Objective: This study aimed to determine the level of anxiety along with anxiety-provoking factors among clinical dental students.

Methods: This study included dental undergraduate and postgraduate clinical students from a public university.

Influence of synthetic and natural photosensitizers activated by photodynamic therapy on extrusion bond strength of fiber post to radicular dentin.

Objective: To assess the effect of different photosensitizers activated by low-level laser therapy on EBS of glass fiber post to radicular dentin.
