Pinwheel Pedicle Flap Technique for Increasing Keratinized Tissue at Stage 2 Implant Surgery.

Introduction: The goal of stage 2 implant surgery is to uncover implants while maintaining or augmenting the peri-implant keratinized tissue. Although the absolute requirement for keratinized tissue around natural teeth can be debated, implants appear to have consistently improved postoperative clinical parameters and health when there is an adequate keratinized peri-implant tissue.

Case Presentation: This article presents a new technique to optimize the keratinized tissue around implants during stage 2 surgery.

Evaluation of the Sealing Capability of the Internal Conical Connections of Implants with Titanium and Zirconia Abutments.

Aim: The purpose of this in vitro investigation was to evaluate the sealing capability of the conical implant-abutment interfaces under different abutment screw torque values using titanium and zirconia abutments with Morse taper designs.

Materials And Methods: A total of 42 dental implants (n = 21 for titanium abutments and n = 21 for zirconia abutments) were inoculated internally with three bacteria. These assemblies were divided into four test groups (n = 10) based on screw fixation torques of 35 or 20 Ncm and placed in sterile broth; the remaining abutments were used as positive controls and torqued to 10 Ncm.

A Comparison of Three Camera Systems for Intraoral Photography.

A single lens reflex camera, a prosumer camera and a smartphone camera were compared for their ability to produce digital intraoral images. Standardized intraoral images produced by the three cameras were evaluated according to sharpness, depth of field, exposure, white balance and image composition. The digital SLR camera was significantly superior to the prosumer camera regarding sharpness and depth of field.

The rate of adverse events during IV conscious sedation.

Conscious sedation has become an integral part of dentistry; it is often used to reduce anxiety or fear in some patients during oral surgery, periodontal surgery, implant placement, and general dentistry procedures. The purpose of this study was to evaluate the frequency of adverse events during IV conscious sedation provided by credentialed general dentists and periodontists in the United States Air Force (USAF). Sedation clinical records (Air Force Form 1417) from calendar year 2009 were requested from all USAF bases.

Effect of repeated refrigerant spray applications using various carriers on pulpal temperature change.

This study sought to determine how repeated applications of a refrigerant spray on various cotton carriers affected the change in pulpal temperature. A thermocouple was placed at the roof of the pulp chamber of a human maxillary canine and connected to a thermometer logging at one-second intervals while the root was immersed in a water bath at 37 degrees C. Four different carrier types were used: large cotton pellets, small cotton pellets, cotton-tip applicators, and cotton rolls.

Retrospective analysis of dental implants among United States Air Force basic military trainees.

Objective: To determine the prevalence of dental implants among the Air Force basic military trainees and to radiographically identify the type of dental implant systems.

Methods: All digital panoramic radiographic images acquired from Oct 1, 2006 through July 31, 2007 of newly recruited Air Force trainees were evaluated for evidence of dental implants. The following data were collected: total number of implants per radiograph, gender and age of subjects, implant location, type of implant retention method, and restorative implant status.

Human periodontal fibroblast response to enamel matrix derivative, amelogenin, and platelet-derived growth factor-BB.

Background: The ideal goal of clinical therapy in periodontal defects is regeneration of all lost structures. For regeneration to occur, cell proliferation, migration, and extracellular matrix synthesis are prerequisites. Attempts at regeneration of periodontal defects by guided tissue regeneration using bone grafts and membranes have not always yielded predictable results.
