Li Jinmeng, Ou Guomin
Digital technology is a new trend in implant dentistry and oral medical technology. Stereolithographic surgical guides, which are computer-guided implant placement, have been introduced gradually to the market. Surgeons are attracted to this approach because of it features visualized preoperative planning, simple surgical procedure, flapless implant, and immediate restoration. However, surgeons are concerned about the accuracy and complications of this approach. This review aims to introduce the classification of computer-guided implant placement...

The development of clinical implant dentistry was intensively affected by dental implant design improvement and innovation, which brought about new concept, even milestone-like changes of clinical protocol. The current improvements of dental implant design and their clinical importance could be highlighted as followings: 1) The implant apical design influences the implant preliminary stability in immediate implant. The apical 3-5 mm design of implant makes implant stable in immediate implant, because this part would be screwed into alveolar bone through fresh socket, the other part of implant could not be tightly screwed in the socket because of smaller implant diameter...

Dental caries is a major disease that threaten human's oral healthy severely with the characteristics of high incidence, low rate of treatment and high rate of retreatment. At present, restorative treatment remains the main method for caries treatment. With the development of the Minimally Invasive Cosmetic Dentistry (MICD), reasonable application of various treatment technologies, maximum preservation of tooth tissues and realizing the maximization of treatment effects become problems that call for immediate solution in dental clinics...

This study evaluated the effect of air-abrasion on t®m phase transformation, roughness, topography and the elemental composition of three Y-TZP (Yttria-stabilized tetragonal zirconia polycrystal) dental ceramics: two conventional (Lava Frame and IPS ZirCad) and one with high-translucency (Lava Plus). Plates obtained from sintered blocks of each ceramic were divided into four groups: AS (as-sintered); 30 (air-abrasion with 30 mm Si-coated Al2O3 particles); 50 (air-abrasion with 50 mm Al2O3 particles) and 150 (air-abrasion with 150 mm Al2O3 particles)...

Digital technology has been widely used in the field of implant dentistry. From a surgical standpoint, computer-guided surgery can be utilized to enhance primary implant stability and to improve the precision of implant placement. From a prosthetic standpoint, computer-aided design/computer-assisted manufacture (CAD/CAM) technology has brought about various restorative options, including the fabrication of customized abutments through a virtual design based on computer-guided surgical planning. This case report describes a novel technique combining the use of a three-dimensional (3D) printed surgical template for the immediate placement of an implant, with CAD/CAM technology to optimize hard and soft tissue healing after bone grafting with the use of a socket sealing abutment...

PURPOSE: The purpose of this study was to assess Canadian and American pediatric dentists' preferred level of participation in clinical decision-making. METHODS: A web-based survey was used to collect the opinions of all active Royal College of Dentists of Canada members and American Academy of Pediatric Dentistry members on the use of direct restorative materials in posterior teeth (n equals 4,648; 19.3 percent response rate). The main survey also included a domain to elicit participants' preferred role in clinical decision-making, ranging from an active role (the dentist takes the primary role in decision-making while considering patients/caregivers opinions) to a passive role (the dentist prefers to have the patient guide the decision-making)...

E King, L Shekaran, A Muthukrishnan
Introduction Record keeping is an essential part of day-to-day practice and plays an important role in treatment, audit and dento-legal procedures. Creating effective endodontic records is challenging due to the scope of information required for comprehensive notes. Two audits were performed to assess the standards of endodontic record keeping by dentists in a restorative dentistry department and students on an endodontic MSc course.Methods Fifty sets of departmental records and 10 sets of student records were retrospectively evaluated against the European Society of Endodontology 2006 guidelines...

The application of the Glass Ionomer Cements in clinical dentistry is recommended due to properties such as fluoride release, chemical adhesion to tooth, negligible setting shrinkage, and coefficient of thermal expansion close to tooth, low creep, and good color stability. However, the cement is vulnerable to early exposure to moisture due to slow setting characteristics. The uses of external energy such as ultrasound and radiant heat (Thermo-curing) have been reported to provide acceleration of the setting chemistry and enhance physical properties...

Internal bleaching in endodontically treated teeth requires care and protection to prevent harm to the periodontal ligament due to peroxide and may result in external root resorption. There is a myriad of treatment options when this occurs, such as monitoring, extraction, and subsequent rehabilitation with implants or fixed prosthodontics. In some cases, such as the one described here, a conservative attempt to maintain the tooth as a single structure can be made by sealing the resorptive defect. In the present case, we show a multidisciplinary approach where orthodontics, periodontics, and restorative dentistry were involved in treating the maxillary right central incisor (#8) of a 65-year-old patient with extensive cervical resorption, whose chief complaint was esthetics...

Objective: To compare the long-term dental treatment effects, oral health habits and oral-health-related qualities of life of children treated under general anesthesia (GA) and passive restraint (PR), respectively. Methods: Twenty seven 2 to 4-year-old children treated under GA and thirty four children treated under PR were recruited in the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology. Up to 2 years after the treatment, a follow up assessment was conducted. The data of general information, dental plaque level and the unplanned treatments were recorded and analyzed...

Self-assessment is a critical skill for health care professionals. Because these professionals must be lifelong, self-directed learners and self-regulating practitioners, the ability to self-assess is essential for them. The aims of this study were to measure how dental students self-assessed and peer-assessed their performance in preclinical operative procedures and to evaluate any relationship between their assessment ability and preclinical skills or academic performance. The study was conducted from 2015 to 2016...

STATEMENT OF PROBLEM: It is clear the contemporary dentist is confronted with a blizzard of information regarding materials and techniques from journal articles, advertisements, newsletters, the internet, and continuing education events. While some of that information is sound and helpful, much of it is misleading at best.

BACKGROUND: One of the disadvantages of the zirconia implants is the lack of elasticity, which is increased with the use of ceramic or zirconia crowns. The consequences that could result from this lack of elasticity have led to the search for new materials with improved mechanical properties. CASE PRESENTATION: A patient who is a 45-year-old woman, non-smoker and has no medical record of interest with a longitudinal fracture in the palatal root of molar tooth 1...

Veterinary dentistry has tended to follow the trends and advancements in the human dental field. As for any procedure performed on a patient, whether human or animal, an informed decision is based on the available evidence regarding treatment options. This is certainly true for the more involved treatments in veterinary dentistry which can include the disciplines of endodontics and dental implantology. A number of published case reports have been accepted by the specialty that endodontic therapy is indeed a predictable and a valuable service that can be offered to pet owners...
