Applying an extended theoretical approach to identifying Canadian dental students' acceptance of teledentistry: A cross-sectional study.

Objective: Teledentistry is a promising innovation for improving service quality and patient outcomes. While studies have shown the relevance of theoretical frameworks in understanding behaviour change predictors for telehealth implementation efforts, their application in dentistry is limited. This study aimed to test different theoretical approaches to identify the factors affecting dental students' behavioural intention to use teledentistry.

Three-Dimensional Printing Methods for Bioceramic-Based Scaffold Fabrication for Craniomaxillofacial Bone Tissue Engineering.

Three-dimensional printing (3DP) technology has revolutionized the field of the use of bioceramics for maxillofacial and periodontal applications, offering unprecedented control over the shape, size, and structure of bioceramic implants. In addition, bioceramics have become attractive materials for these applications due to their biocompatibility, biostability, and favorable mechanical properties. However, despite their advantages, bioceramic implants are still associated with inferior biological performance issues after implantation, such as slow osseointegration, inadequate tissue response, and an increased risk of implant failure.

A technique to guide implant placement with the long axis parallel to the path of insertion of removable partial dentures.

This article describes a novel technique that allows the planning and placing of dental implants with their long axis parallel to a path of insertion chosen for a prospective removable partial denture. The technique is straightforward, uses digital technologies efficiently, and enables prosthetically driven implant placement. It also optimizes the outcome when dental implants are used in association with removable partial dentures.

Do onlays and crowns offer similar outcomes to posterior teeth with mesial-occlusal-distal preparations? A systematic review.

Objective: Teeth prepared for mesial-occlusal-distal (MOD) restorations have a significant risk of cusp fracture. Crowns and onlays can provide cusp coverage to reinforce posterior teeth at risk. Onlays are often more conservative of tooth structure which may be an advantage for teeth with large MOD preparations.

Virtual Oral Health across Canada: A Critical Comparative Analysis of Clinical Practice Guidances during the COVID-19 Pandemic.

During the COVID-19 pandemic, teledentistry was suggested as a cost-effective and promising approach to improve access to oral health care. In response, Canadian provincial and territorial dental regulatory authorities (DRAs) published teledentistry-related clinical practice guidances (TCPGs). However, an in-depth comparison between them is needed to understand their gaps and commonalities so as to inform research, practice, and policy.

Management of atypical occlusal discrepancy after condylar resection: A clinical report.

This clinical report describes the prosthetic management of occlusion for a patient who had received condylar resection as part of cancer treatment. Previous reports have identified that patients with unrepaired segmental resection of the mandible experienced a frontal plane rotation of the mandible toward the nonsurgical side. In contrast, because of preservation of temporomandibular muscles and their attachments, the mandible rotated toward the surgical side, and occlusal contacts were limited to a pair of molars on that side.

Comparison of the torque transferred to the implant-bone interface when tightening abutment screws and when torque testing implants: An in vitro study.

Statement Of Problem: Before dental implants are restored, osseointegration is often verified by torque testing the implant. For this test, it might be appropriate to select the torque subsequently used to tighten the abutment screw during prosthetic delivery. However, whether the full torque applied to the abutment screw is transferred to the implant-bone interface remains unknown.

A Prolonged Time to Diagnosis Due to Misdiagnoses: A Case Report of an Atypical Presentation of Eagle Syndrome.

BACKGROUND Eagle syndrome is an unusual condition in which the styloid process (SP) becomes elongated and causes different clinical symptoms due to pressure on adjacent anatomical structures. The symptoms are non-specific and include severe throat, facial, and ear pain, or headaches. They are usually exacerbated by head rotation, swallowing, yawning, or chewing, but atypical presentations exist.

Fracture Resistance of Immature Teeth Submitted to Different Endodontic Procedures and Restorative Protocols.

Introduction: The purpose of this in vitro study was to determine whether the methods used to treat endodontically and restore anterior immature teeth with a necrotic pulp influence their resistance to fracture.

Methods: After access opening and cleaning and shaping, 80 specimen teeth were assigned into 5 groups according to the endodontic obturation method and coronal restoration as follows: A1, apexification with a composite restoration in the crown area; A2, apexification with a composite restoration in the crown and 3 mm into the root; IR, immediate revascularization with a composite restoration in the crown area; SR, successful revascularization with a composite in the crown area; and the control group, a mature tooth treated with gutta-percha and sealer with a composite restoration in the crown area. The teeth were mounted in acrylic blocks and brought to fracture under compressive forces in a universal testing machine.

Reversing the Effects of 0.5% Bupivacaine Using Phentolamine Mesylate: A Preliminary Randomized Controlled Clinical Trial.

Phentolamine mesylate is the only commercially available dental local anesthetic reversal agent. It has been proven safe and effective for reversing most local anesthetics used in dentistry but was never tested with bupivacaine. The aim of this project was to evaluate the effectiveness of 0.

Resistance to fracture of extracted teeth used for pre-clinical endodontic procedures: Influence of storage conditions.

Objectives: The purpose of this in vitro study was to determine whether different storage conditions used during endodontic procedures affect the fracture resistance of extracted teeth used for pre-clinical dental education.

Methods: Freshly extracted mandibular incisors and canines were sterilised in an autoclave for 40 minutes at 24°F under a pressure of 20 psi and then stored in distilled water at 4°C until use. Specimens were randomly assigned to two groups based on the storage method used whilst undergoing endodontic procedures.

Use of a dental surveyor to ensure optimal seating of implant overdenture attachments.

Many implant overdenture attachments accommodate divergent abutments. However, there can be instances where the denture base resin surrounding the abutment may impede seating by binding on the axial surface(s) of the abutment. This article describes the use of a dental surveyor to aid clinicians in determining where the resin denture base might be preventing the seating of overdenture attachments.

Reversing the effects of 2% Lidocaine: A randomized controlled clinical trial.

Objectives: Prolonged soft tissue anesthesia following a dental appointment is a complaint that is frequently reported by patients. Soft tissue anesthesia generally exceeds the duration of pulpal anesthesia by a few hours. This can lead to difficulties with smiling, drinking, speaking and lip/cheek biting following dental appointments.

Effect of Different Disinfection/Sterilization Methods on Risk of Fracture of Teeth Used in Preclinical Dental Education.

The aim of this in vitro study was to determine whether different disinfection/sterilization methods affected the risk of fracture of extracted teeth used for preclinical dental education. Freshly extracted intact mandibular incisors were assigned to different groups according to the processing method used. In the autoclave group (n=20), teeth were autoclaved for 40 min at 240°F under a pressure of 20 psi; in the formalin group (n=20), teeth were immersed in 10% formalin for two weeks; and in the control group (n=10), teeth were not processed.

Effect of universal adhesive etching modes on bond strength to dual-polymerizing composite resins.

Statement Of Problem: Information is lacking as to the effect on bond strength of the etching modes of universal adhesives when they are used to bond dual-polymerizing composite resins to dentin.

Purpose: The purpose of this in vitro study was to investigate the bonding of dual-polymerizing foundation composite resins to dentin when universal bonding agents are used in self-etch or etch-and-rinse modes.

Material And Methods: Sixty caries-free, extracted third molar teeth were sectioned transversely in the apical third of the crown and allocated to 12 groups (n=5).

Digital scanning to aid guiding plane and rest seat preparations for removable partial dentures.

This article describes the use of a digital intraoral scanner to aid clinicians making rest seat and guiding plane preparations, simplifying the procedure and reducing the time needed to analyze the abutment modifications. No additional equipment is required other than a diagnostic cast and a digital scanner with preparation comparison software.

Compatibility between dental adhesive systems and dual-polymerizing composite resins.

Statement Of Problem: Information is lacking about incompatibilities between certain types of adhesive systems and dual-polymerizing composite resins, and universal adhesives have yet to be tested with these resins.

Purpose: The purpose of this in vitro study was to investigate the bonding outcome of dual-polymerizing foundation composite resins by using different categories of adhesive solutions and to determine whether incompatibilities were present.

Material And Methods: One hundred and eighty caries-free, extracted third molar teeth were allocated to 9 groups (n=20), in which 3 different bonding agents (Single Bond Plus [SB]), Scotchbond Multi-purpose [MP], and Scotchbond Universal [SU]) were used to bond 3 different composite resins (CompCore AF [CC], Core Paste XP [CP], and Filtek Supreme Ultra [FS]).

Hereditary gingival fibromatosis with extreme ridge thickness and insufficient interarch distance: A clinical report of surgical and prosthetic management.

Hereditary gingival fibromatosis is a rare genetic disorder resulting in gingival overgrowth that can be found in both dental arches. As a result of the gingival overgrowth and associated dental displacement, affected patients occasionally present with increased occlusal vertical dimension and/or inadequate lip closure. Depending on the disorder's severity, these patients can be challenging to treat.

Implant-assisted complete prostheses.

The current review was undertaken to obtain a better understanding of the knowledge base of implant-assisted complete dental prostheses (fixed and removable) in the treatment of the completely edentulous maxilla or mandible. Indications, advantages and disadvantages, complications and maintenance issues, as well as the cost-effectiveness of both treatments, are discussed to help clinicians in their therapeutic decision-making. In summary, when indicated and depending on the patients' needs, both removable and fixed implant-assisted prostheses are highly safe, reliable and satisfactory treatment modalities for the rehabilitation of edentulous jaws.

Localised irradiance distribution found in dental light curing units.

Objective: To measure the localised irradiance and wavelength distributions from dental light curing units (LCUs) and establish a method to characterise their output.

Methods: Using a laboratory grade integrating sphere spectrometer system (Labsphere and Ocean Optics) the power, irradiance, and spectral emission were measured at the light tips of four LCUs: one plasma-arc (PAC) unit, one single peak blue light-emitting diode (blue-LED) unit, and two polywave LED (poly-LED) units. A beam profiler camera (Ophir Spiricon) was used to record the localised irradiance across the face of the light tips.
