Gingival recession is a common clinical condition that creates unfavorable esthetics and dentinal hypersensitivity. Treatment of gingival recession aims to create or increase keratinized tissue and provide root coverage. The aim of this article is to present 2 clinical cases of severe Miller Class II gingival recession with absence of keratinized tissue. Each patient was treated with a free gingival graft associated with a coronally positioned flap. Follow-up indicated that the use of the free gingival graft was effective in increasing keratinized tissue and in covering the recession in a satisfactory manner...

Following injury to a peripheral nerve, patients may complain of pain over the distribution of the same contralateral nerve, a phenomenon referred to as contralateral pain or mirror pain (MP). Symptoms of MP usually begin after the neuropathic pain from the original nerve injury has become chronic. Chronic neuropathic pain can lead to sensitization and spread of pain. Because the diagnosis of MP can be missed, patients may undergo multiple treatment procedures that prove to be ineffective in relieving the pain...

Schwannomas (also known as neurilemomas) are benign tumors that arise from the Schwann cells of the nerve sheath. While they seldom occur in the oral cavity, the tongue is the most common site. Palatal schwannomas are extremely rare. This article reports a case of a large, slowly developing schwannoma that caused bone erosion in the hard palate of an 18-year-old man. The diagnosis was based on histopathologic and immunohistochemical findings. The tumor was completely excised, and no recurrence was observed at a 1-year follow-up...

The simple bone cyst (SBC) is a benign intraosseous lesion that is considered to be a pseudocyst because the cystic cavity does not present an epithelial lining. The most accepted theory regarding its etiology is that the SBC develops when the blood clot fails to organize subsequent to bleeding caused by trauma. The SBC is asymptomatic, and therefore the diagnosis is made through routine imaging examinations. In imaging examinations, the lesion is characterized by a radiolucent, unilocular, well-delimited appearance and an irregular or scalloped contour with or without a sclerotic halo...

The frenum is a mucosal fold that attaches the lips or cheeks to the alveolar mucosa, gingiva, and underlying periosteum. Consequences of an abnormal frenal attachment include gingival recession, decreased vestibular depth, decreased range of lip movement, and involvement of interdental papilla, causing a diastema. Several methods to eliminate ectopic frenal attachments have been suggested, including frenectomy (elimination) and frenotomy (repositioning). This case report describes the use of a modified frenectomy technique in a 15-year-old girl with excess gingiva between the maxillary central incisors, which exhibited a 3-mm diastema...

Medical emergencies are not uncommon in dental practices. Syncope has commonly been found to account for the majority of these emergencies in a dental setting, but some studies have reported cardiovascular events as the most common type of emergency. It is critical that every dentist be prepared with the knowledge and equipment necessary to respond in emergency situations. This article aims to provide dentists with essential knowledge about management of cardiovascular emergencies.

Soft tissue integration in the transmucosal zone of dental abutments supports the peri-implant tissues, improves esthetics, ensures soft tissue seal against microorganisms, and preserves crestal bone level. 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. An electronic search of the PubMed/MEDLINE database was performed, seeking relevant English-language articles published between January 1, 2003, and October 11, 2014...

The purpose of this study was to compare the marginal fit of press-fabricated lithium disilicate crowns with that of computer-aided design/computer-aided manufacturing (CAD/CAM) lithium disilicate crowns to determine if the fabrication method has an influence on marginal fit. The marginal fit of 25 pressed and 25 CAD/CAM crowns was measured using the replica technique. The sites measured were the mesial, distal, facial, and lingual margins. A microscope at 10× magnification was used to obtain the measurements...

The aim of this case report is to describe the treatment of an 11-year-old boy who was referred to an endodontist for evaluation of external inflammatory root resorption in the distal apical third of the permanent maxillary left lateral incisor, caused by deviation in the eruption path of the permanent maxillary left canine. The results of the pulpal sensitivity test of the permanent maxillary left lateral incisor were inconclusive and similar to those for the homologous tooth, so the endodontist opted for a clinical and radiographic follow-up...

The combination of ethylenediaminetetraacetic acid (EDTA) and sodium hypochlorite (NaOCl) has been suggested as an irrigant for root canal therapy. However, the chemical interaction between these agents is a complex subject that is not completely understood. The aim of this study was to evaluate the interference of an EDTA chelating agent in the antibacterial ability of NaOCl, while also considering variations in methodology. Various concentrations of NaOCl and EDTA solutions were prepared from 6% and 17% solutions, respectively...

This study analyzed nanostructured silver vanadate (AgVO3) films on certain substrate surfaces found in dental implant devices in order to see if these films promote antimicrobial activity. Enamel and glaze vehicles were used to apply the nanomaterial (0.0% [control], 2.5%, 5.0%, and 10.0% concentrations) on 3 substrates (280 specimens per substrate): polytetrafluoroethylene (PTFE), polyacetal, and acrylic resin. An agar diffusion method was performed in triplicate to determine the antimicrobial activity against 8 microorganisms...

Bleaching is a conservative treatment for discolored teeth, but the effect of this treatment on newer, silorane-based composite resins is unclear. This study evaluated the effect of at-home bleaching on the microhardness of methacrylate- and silorane-based composites. Forty blocks each of a methacrylate-based composite and a silorane-based composite were prepared. The 80 specimens were tested in 8 groups (n = 10): 2 composites, each exposed to 3 different carbamide peroxide concentrations (10%, 16%, or 22%) as well as distilled water (control)...

Due to improvements in esthetic dentistry, the number of patients seeking to obtain a more harmonious smile has increased. A 40-year-old woman was referred for treatment because she was dissatisfied with the effect that diastemas and a conoid tooth had on her smile. Her maxillary anterior teeth were relatively short, resulting in a compromised esthetic relationship between height and width. Orthodontic treatment for better distribution of her teeth was recommended to the patient, but she refused, wanting faster and less expensive treatment...

Polishing techniques are known to enhance the longevity and appearance of composite resin restorations. However, the influence of the timing of polishing on the final results of a restoration is not well documented. The aim of this study was to determine the effect of immediate and delayed polishing on the color stability of a composite resin. Sixty composite resin specimens were fabricated and randomly divided into 2 groups according to immersion solutions: group 1, deionized water (control); and group 2, coffee (as staining solution)...

Traumatic bone cysts (TBCs) are uncommon intraosseous lesions, classified as pseudocysts because they lack an epithelial membrane lining. The etiology of a pseudocyst has not been determined. Various hypotheses have been put forward to explain its pathogenesis, of which the traumatic-hemorrhagic theory is the most commonly accepted. Minor trauma, insufficient to cause fracture or iatrogenic injury, is commonly implicated as the stimulus initiating cyst formation. A TBC presenting after jaw fracture has been rarely reported in the literature...

The aim of this study was to evaluate the fluorination of a zirconia surface as an alternative treatment for bonding to resin cement; the null hypothesis was that fluorination would not improve adhesion values. Four different surface treatments were performed on the surface of yttria-stabilized tetragonal zirconia polycrystal discs (N = 80): Ctrl (control), no treatment; SB, sandblasting with 50-μm alumina particles; SBS, sandblasting with 30-μm silica-modified alumina particles and application of silane; and SF, fluorination with sulfur hexafluoride-containing plasma...
