Change of salivary fluoride level with intake of fluoride releasing lozenges: A pilot study.

Aim: Long-term, low-level fluoride concentrations in saliva are highly effective in caries prevention and remineralization. The aim of the present two-phased study was to test whether fluoride-releasing lozenges compared to placebo significantly raise salivary fluoride levels above baseline achieved by 1100 ppm fluoride toothpaste in a double-blind, crossover pilot study.

Methods: In phase 1, a four-arm crossover basic study, four participants used one dissolvable lozenge with .

Integrating Caries Management by Risk Assessment (CAMBRA) and Prevention Strategies Into the Contemporary Dental Practice.

In the past, the dental profession has adhered to a rigid tenet: remove decay from a tooth and then restore, a mindset that has been proverbially dubbed as "drill and fill." Today, dental caries is recognized as an infectious disease that affects children and adults throughout life. The philosophy of CAries Management By Risk Assessment, or CAMBRA®, represents a paradigm shift.

Approximal and occlusal carious lesions: Restorative treatment decisions by California dentists.

Background: Investigators use questionnaire surveys to evaluate treatment philosophies in dental practices. The aim of this study was to evaluate the management strategies California dentists use for approximal and occlusal carious lesions.

Methods: In May 2013, the authors e-mailed a questionnaire that addressed approximal and occlusal carious lesion management (detection and restorative threshold, preferred preparation type, and restorative materials) to 16,960 dentists in California.

A Review of the Positive Influence of Crown Contours on Soft-Tissue Esthetics.

Successful crown restorations duplicate the natural tooth in hue, chroma, value, maverick colors, and surface texture. Equally important is the visual harmony of the facial and proximal soft-tissue contours, which requires the collaborative skills of the restorative dentist, periodontist, and dental technician. The treatment team must understand the biologic structures adjacent to natural dentition and dental implants.

Retrospective analysis of porcelain failures of metal ceramic crowns and fixed partial dentures supported by 729 implants in 152 patients: patient-specific and implant-specific predictors of ceramic failure.

Statement Of Problem: Porcelain fracture associated with an implant-supported, metal ceramic crown or fixed partial denture occurs at a higher rate than in tooth-supported restorations, according to the literature. Implant-specific and patient-specific causes of ceramic failure have not been fully evaluated.

Purpose: The purpose of this retrospective study was to evaluate the potential statistical predictors for porcelain fracture of implant-supported, metal ceramic restorations.

A simplified method to develop optimal gingival contours for the single implant-supported, metal-ceramic crown in the aesthetic zone.

Prosthetic replacement of the missing single maxillary central incisor with an implant-supported crown represents a profound aesthetic challenge for the restorative dentist, laboratory technician, and surgeon. In addition to the visual fidelity of color, translucency, contour, and surface texture, the proper soft tissue outline is sacrosanct to the illusion of a natural tooth. The contrast between the uniformly round shoulder of the implant and the tooth's curvilinear cementoenamel junction is particularly problematic.

Retrospective analysis of 56 edentulous dental arches restored with 344 single-stage implants using an immediate loading fixed provisional protocol: statistical predictors of implant failure.

Purpose: The purpose of this retrospective study was to evaluate the effects of implant dimensions, surface treatment, location in the dental arch, numbers of supporting implant abutments, surgical technique, and generally recognized risk factors on the survival of a series of single-stage Straumann dental implants placed into edentulous arches using an immediate loading protocol.

Materials And Methods: Each patient received between 4 and 18 implants in one or both dental arches. Periapical radiographs were obtained over a 2- to 10-year follow-up period to evaluate crestal bone loss following insertion of the definitive metal-ceramic fixed prostheses.

Tissue-directed placement of dental implants in the esthetic zone for long-term biologic synergy: a clinical report.

Implant dentistry steadily evolves as more is learned about the unique biologic interrelationship of the dental implant restoration and the surrounding hard and soft tissues. Important factors include the impact of the surface microtopography on biochemically-mediated cell differentiation, the unavoidable bacterial colonization of the implant-abutment (or crown) microgap, the vertical and horizontal dimensions of biologic width, and the histology of surrounding structures. The recipient site, implant design, surgical technique, and location of the restorative platform significantly influence the optimal esthetics and biologic stability of implant restorations.

The use of a trephine biopsy needle to obtain autogenous corticocancellous bone from the iliac crest: technical note.

In the absence of adequate bone height, augmentation of the maxillary antrum prior to placement of endosseous implants is a well-established procedure. Although there is a debate among clinicians as to which grafting materials are the most advantageous, autogenous bone is still considered by many to be the gold standard. Often patients require more graft material than is generally available from intraoral sites.

Development of gingival esthetics in the edentulous patient prior to dental implant placement using a flangeless removable prosthesis: a case report.

Development of gingival contours found in healthy natural dentitions enhances the esthetic results achieved with implant-supported fixed prostheses. However, this endeavor is frequently difficult to achieve, especially in the completely edentulous patient. Edentulous patients with optimal hard and soft tissue can be treated with a specially designed removable prosthesis that will develop gingival contours prior to implant placement.

Development of gingival esthetics in the terminal dentition patient prior to dental implant placement using a full-arch transitional fixed prosthesis: a case report.

Despite significant advances in dental therapeutics, there are patients for whom no reasonable treatment is available that will reliably restore or maintain their existing dentition. The causes of future edentulism include advanced caries, failing root canal therapy, inadequate numbers of teeth to support a fixed prosthesis, untreatable periodontal disease, or a history of failed previous rehabilitations. For these patients, dental implants may provide a more predictable future than retention of their remaining teeth.

Development of gingival esthetics in the edentulous patient with immediately loaded, single-stage, implant-supported fixed prostheses: a clinical report.

Many clinicians have reported on the success of immediately loaded implants supporting a bilaterally stabilized provisional fixed prosthesis. This protocol offers several advantages, including increased masticatory function, minimized uncontrolled transmucosal loading through cross-arch stabilization, improvement of psychologic well-being, and reduction in treatment time. However, the development and maintenance of proper dentogingival esthetics in the edentulous maxilla presents substantial challenges for the implant team.

The treatment dilemma of the furcated molar: root resection versus single-tooth implant restoration. A literature review.

Successful treatment of furcated molar teeth presents the periodontist and prosthodontist with a challenging dilemma. Accepted treatment modalities include chemotherapeutic maintenance, root planning, open flap debridement, modified Widman flap, bone grafting with and without guided tissue regeneration, and osseous resection with and without root removal. Determining the appropriate treatment for an individual patient that is both cost-effective and offers the greatest long-term prognosis can be a daunting task.

Fabrication of treatment restorations using acrylic resin denture teeth.

A technique is disclosed for fabricating esthetic, long-term treatment restorations by using acrylic resin denture teeth facings. The advantages of this method for provisional restoration construction are reduced costs and predictable, satisfying results.
