Implants Response of soft tissue to different abutment materials with different surface topographies: a review of the literatureFull Article (PDF) Self-Instruction Exercise No. 414
Feras Al Rezk
The aim of this literature review was to define the most favorable surface topography and macrodesign of the transmucosal zone of abutments to achieve optimal soft tissue seal. A search identified 12 articles—3 human studies, 3 animal studies, and 6 in vitro studies—meeting the inclusion criteria for final evaluation. The human histologic studies showed that laser-ablated, hydrophilic, and oxidized titanium surfaces result in perpendicular insertion of human gingival fibroblasts into the treated abutment surface. Epithelial cells seem to slightly favor zirconia and polished titanium surfaces.

Orofacial Pain Development of mirror pain following trigeminal nerve injury: a case report and review of neuropathic mechanismsFull Article (PDF) Self-Instruction Exercise No. 415
James A. Giglio
John M. Gregg
Mirror pain (MP) develops contralateral to the site of injury to a peripheral nerve, usually after neuropathic pain from the original nerve injury has become chronic. If the diagnosis of MP is missed, the patient may undergo treatment procedures that prove to be ineffective in relieving the pain. This article presents a case of apparent MP that appeared approximately 20 months following inferior alveolar nerve injury during placement of a dental implant.

Oral and Maxillofacial Surgery A modified frenectomy technique: a new surgical approachFull Article (PDF) Self-Instruction Exercise No. 416
Mehdi Ekhlasmand Kermani
This article describes a modified surgical technique for management of ectopic frena. A combination of frenectomy, papilla preservation flap, and frenotomy, the technique is designed to minimize the surgical scar on the buccal surface and preserve the papilla, thereby yielding optimal esthetic results.

Basic Science The effect of home bleaching carbamide peroxide concentration on the microhardness of dental composite resinsFull Article (PDF)
A study evaluating the effect of home bleaching on the microhardness of methacrylate- and silorane-based composite resins found that all carbamide peroxide concentrations (10%, 16%, and 22%) significantly decreased the microhardness of the methacrylate groups but significantly increased the microhardness of the silorane groups. There was no evident difference among the effects of the different gel concentrations (P > 0.05).

Fixed Prosthodontics A comparison of marginal fit between press-fabricated and CAD/CAM lithium disilicate crownsFull Article (PDF)
Richard S. Carlile
Wade H. Owens
William J. Greenwood
Peter H. Guevara
In an in vitro study, press-fabricated lithium disilicate crowns provided a better marginal fit than lithium disilicate crowns fabricated via computer-aided design/computer-aided manufacturing. However, both fabrication methods resulted in crowns with a clinically acceptable marginal fit.

Medical Emergency Training Cardiovascular considerations for the dental practitioner. 2. Management of cardiac emergenciesFull Article (PDF)
Medical emergencies are not uncommon in dental practices. Syncope has commonly been found to account for the majority of emergencies in a dental setting, but some studies have reported cardiovascular events as the most common type of emergency. This article aims to provide dentists with essential knowledge about the management of cardiovascular emergencies.

The simple bone cyst (SBC) is a benign, asymptomatic intraosseous lesion radiographically characterized by a radiolucent, unilocular, well-delimited appearance and an irregular or scalloped contour with or without a sclerotic halo. This case report describes an SBC in the mandibular condyle, discovered incidentally on imaging examinations.

Two patients with mandibular incisors exhibiting Miller Class II gingival recession and no keratinized tissue were treated with a 2-stage procedure involving a free gingival graft and a coronally positioned flap. Follow-up indicated that the combined approach was effective in increasing keratinized tissue and covering the recession.

This study analyzed nanostructured silver vanadate (AgVO3) films on substrate surfaces found in dental implant devices to see if the films would promote antimicrobial activity. Surface treatment with films containing AgVO3 in concentrations of 5.0% and 10.0% promoted antimicrobial activity on substrates, findings that have potential applications in implant dentistry.

This study evaluated the interference of an ethylenediaminetetraacetic acid (EDTA) chelating agent in the antibacterial ability of sodium hypochlorite (NaOCl). When NaOCl and EDTA were premixed, high concentrations (17% and 8.5%) of EDTA prevented the complete killing of Enterococcus faecalis by NaOCl. When NaOCl and EDTA were added simultaneously to a bacterial suspension without premixing, NaOCl was able to exert its full bactericidal action.

Endodontics External resorption of a maxillary incisor associated with a canine with a deviating eruption path: a case reportFull Article (PDF)
César Augusto Pereira Oliveira
Patrícia Maria Poli Kopper
This case report describes conservative treatment of external inflammatory root resorption affecting a permanent lateral incisor in a child. Because the results of pulpal sensitivity tests were inconclusive, the endodontist opted for regular follow-up rather than root canal therapy. After 3 years of monitoring, bone repair with dental remodeling was observed.
