Challenge-Based Learning in Dental Education.

Challenge-based learning (CBL) is a novel learning framework for a collaborative and multidisciplinary learning experience. It allows students, teachers, stakeholders, researchers, families, and society to work together to identify and solve real-world challenges. CBL helps students develop a deeper knowledge of the subjects they are studying.

Update on Dental Luting Materials.

A dental luting material aids in the retention and stability of indirect restorations on the prepared tooth structure. In dentistry, clinicians are using a wide range of luting materials for the cementation of indirect restorations. Zinc oxide eugenol and non-eugenol cements, zinc phosphate cement, zinc polycarboxylate cement, glass ionomer cement and resin cements are common dental cements used in dentistry.

Tunnel Restoration: A Minimally Invasive Dentistry Practice.

With advances in technology, dentists nowadays manage dental caries with the philosophy of minimally invasive dentistry. Dental restoration is now performed most conservatively with minimal destruction of tooth structure when operative dentistry is indicated. Some operative dentists suggested using tunnel restoration for treating proximal caries as a conservative alternative to the conventional box preparation.

Use of Computer Simulation in Dental Training with Special Reference to Simodont.

Simulation-based dental education has been increasingly implemented in dental training. Virtual reality simulators are being explored as an adjunct to dental education. Simulation-based dental education could serve as a powerful aid to preclinical instruction.

Nonrestorative Management of Dental Caries.

The World Dental Federation (FDI) policy statement in 2016 advocated evidence-based caries-control measures for managing dental caries. The caries management philosophy has shifted from the traditional surgical manners to minimal intervention dentistry. Minimal intervention dentistry aims to extend the longevity of natural teeth.

Distal Extension Denture - Case Report and Overview.

Replacing missing teeth distal to the last standing teeth with removable partial dentures poses considerable challenge to dentists. However, the insertion of implants turns a free-end saddle into a bounded saddle. Still, patients may not be able to accept implant insertions due to financial reasons, systemic medical conditions, local anatomical factors or complicated treatments involving surgery.

Prosthodontic Rehabilitation and Follow-Up Using Maxillary Complete Conventional Immediate Denture.

Despite global efforts to improve individuals' oral health, a considerable proportion of patients still progress to the stage in which the extractions of all teeth in one arch or both are indicated. An immediate complete denture remains a relatively accessible treatment option, particularly for those patients who cannot afford or do not need implant treatment. It is often one of the best solutions when the complete extraction of the remaining teeth is unavoidable.

Improving Esthetics of Removable Partial Dentures Using Palatal Retentive Arms.

A well-designed removable partial denture can replace the loss of hard and soft tissues, restore masticatory function and maintain arch integrity. It is relatively simple, non-invasive and economical compared to other treatment options. Removable partial denture is therefore a common option among various treatment replacing missing teeth.

Clinical studies on core-carrier obturation: a systematic review and meta-analysis.

Background: This systematic review aimed to evaluate the clinical performance of core-carrier obturation in endodontic treatment.

Methods: Keywords of "(core carrier OR Thermafil) OR (cold lateral condensation OR lateral condensation) OR (warm vertical condensation OR vertical condensation) AND (obturation OR root canal filling) AND clinical study" were searched for all obtainable publications up to year 2017 in the databases of PubMed, ScienceDirect, EMBASE, Scopus and Web of Science. The success rate, short-term postoperative pain, overfilling and adaptation of core-carrier obturation from clinical studies were selected.

Treatment outcomes of single-visit versus multiple-visit non-surgical endodontic therapy: a randomised clinical trial.

Background: Clincians have been providing single-visit and multiple-visit endodontic treatments for their patients. This study aims to compare the success rate, prevalence of postoperative pain and chairside time of single-visit and multiple-visit endodontic treatments.

Method: Patients who required primary endodontic treatment in a university dental clinic were randomly allocated to two general dentists for single-visit or multiple-visit treatments using the same materials and procedures.

Incidence of post-obturation pain after single-visit versus multiple-visit non-surgical endodontic treatments.

Background: Post-obturation pain is frustrating to both patients and dentists. Its incidence may change with the use of contemporary endodontic techniques. This randomised clinical trial aims to compare the incidence of post-obturation pain at one and seven days after single-visit and multiple-visit non-surgical endodontic treatments.

Perceptions of single-visit and multiple-visit endodontic treatment: a survey of endodontic specialists and general dentists in Hong Kong.

Aim: To study the preference of practice for single- and multiple-visit endodontic treatment by Hong Kong endodontists and general dental practitioners (GDPs), and to investigate their reasons for choosing single- or multiple-visit treatment in their practice.

Method: An anonymous questionnaire was mailed to all 16 registered endodontists and 800 randomly selected GDPs in Hong Kong to explore their preference and reasons for selecting single- or multiple-visit endodontic treatment for their patients. Information on the use of magnifying loupes, microscopes and the number of years they have been in dental practice was also collected.

Treatment time for non-surgical endodontic therapy with or without a magnifying loupe.

Background: Use of magnifying loupe may increase the efficiency of dental care. This clinical trial compared the time in performing non-surgical endodontic therapy with or without the use of a magnifying loupe.

Methods: Patients who required primary endodontic treatment in clinical trial centres at the University of Hong Kong (HKU) in Hong Kong and Peking University (PKU) in Beijing were invited to participate in this study.
