Peter Yu Tsao Pan, Wendy Wang Chia Wei, Ling Loh Poey, Liang Shen, Victoria Yu Soo Hoon
A well-constructed essay is indicative of deep strategic understanding and is considered a valid assessment tool in many dental schools. It has been suggested that constructing MCQs could be an effective learning tool for students while at the same time contribute towards a pool of well-constructed MCQs that could stand up to scrutiny at high-stakes examinations. This study aimed to compare the quality of essays written by students trained and untrained in MCQ construction. The null hypothesis was that construction of MCQs did not result in higher grades achieved in "closed-book" time-limited assessment conditions...

Toshihito Takahashi, Tomoya Gonda, Yoko Mizuno, Yozo Fujinami, Yoshinobu Maeda
BACKGROUND: Removable prothodontics are often associated with mechanical troubles in daily use, such as fracture or deformation. These troubles render prostheses unusable and reduce wearers' QOL. Various reinforcements are used to prevent such problems, but consensus on reinforcement has not been reached. OBJECTIVE: This review aimed to summarize the effects of reinforcement, and to propose favorable reinforcement based on material, design, and position in the prostheses...

BACKGROUND: The reconstruction of a large mandibular defect poses a challenging issue in oral cancer ablation surgery. One popular option for mandibular continuity reconstruction after tumor resection involves the use of a reconstruction plate (R-plate), which maintains space and contour without bone harvesting. An R-plate, however, cannot provide final functional loading rehabilitation with implants or dentures. METHODS: We suggest a new method of functional mandibular reconstruction using retentive posts and an upper prosthesis...

A cross-sectional survey to investigate the use of intra radicular posts in clinical practice was distributed to GDPs attending continuing professional development lectures and delegates of a specialist prosthodontic conference. Fifty-six (51%) GDP's and fifty-three (49%) conference delegates responded. Forty-five percent of GDP's exclusively used metal posts in comparison to 25% of the conference delegates. The findings of this study suggest there are no differences in the use of intra-radicular posts between GDPs and conference delegates...

Daniele Manfredini, Carlo E Poggio
STATEMENT OF PROBLEM: The presence of temporomandibular disorders (TMDs) and/or bruxism signs and symptoms may present multifaceted concerns for the prosthodontist. PURPOSE: The purpose of this systematic review was to evaluate the relationship between prosthetic rehabilitation and TMDs and bruxism. MATERIAL AND METHODS: Three research questions were identified based on different clinical scenarios. Should prosthodontics be used to treat TMD and/or bruxism? Can prosthodontics cause TMDs and/or bruxism? How can prosthodontics be performed (for prosthetic reasons) in patients with TMDs and/or bruxism? A systematic search in the PubMed database was performed to identify all randomized clinical trials (RCTs) comparing the effectiveness of prosthodontics with that of other treatments in the management of TMDs and/or bruxism (question 1); clinical trials reporting the onset of TMDs and/or bruxism after the execution of prosthetic treatments in healthy individuals (question 2); and RCTs comparing the effectiveness of different prosthodontics strategies in the management of the prosthetic needs in patients with TMDs and/or bruxism (question 3)...

PURPOSE: On maxillofacial tumor patients, oral implant placement prior to postoperative radiotherapy can shorten the period of prosthetic reconstruction. There is still lack of research on effects of post-implant radiotherapy such as healing process or loading time, which is important for prosthodontic treatment planning. Therefore, this study evaluated the effects of post-implant local irradiation on the osseointegration of implants during different healing stages. MATERIALS AND METHODS: Custom-made implants were placed bilaterally on maxillary posterior edentulous area 4 weeks after extraction of the maxillary first molars in Forty-eight Sprague-Dawley rats...

Dental fluorosis results from excess fluoride ingestion during tooth formation and is commonly seen in certain endemic areas. Its clinical manifestations may range from white opaque patches of enamel in mild cases to pitting and loss of enamel in severe cases. The treatment of fluorosis is important not only because of esthetic and functional concerns but also to help improve a patient's self-esteem; therefore, a multidisciplinary approach is often necessary. This article describes a multidisciplinary approach to complete-mouth rehabilitation of a patient affected with fluorosis...

At the heart of prosthodontic treatment planning must be a sound understanding of the quality and reliability of the prosthodontic foundation. Implant prosthodontics relies almost entirely on the biological and mechanical properties of an osseous foundation. Initiation of therapy in the absence of a healthy and stable prosthodontic foundation risks unintended and suboptimal treatment outcomes. For conventional removable partial denture (RPD) therapy, consideration must be given to interactions between the soft and hard tissues available to support and stabilize planned prostheses...

Gunshot injuries to the face can have serious aesthetic, functional, and psychological consequences. The incapacitating nature of maxillofacial defects makes reconstruction of the maxilla and mandible challenging, owing to multiple surgeries and extensive rehabilitation phase. Outcome of prosthodontic treatment is one of the important parameters by which a patient measures the success of rehabilitation. A 5-year follow-up of comprehensive surgical and prosthodontic reconstruction of a gunshot injury using dental implants is described...
