Aberrations in the internal dental anatomy present challenges for clinicians performing endodontic therapy. These challenges have been partly resolved in recent years by a more comprehensive knowledge of root canal anatomy as well as advancements in the endodontic armamentarium. The aim of this case series is to describe successful root canal treatment, under magnification, in 3 cases of mandibular first molars with 6 root canals. Two of these teeth had 2 roots (mesial and distal) with 3 canals in each root; the third tooth had 3 root canals located mesially and 3 present distally as well as a radix entomolaris...

Enamel defects, such as white or yellow-brown spots, usually cause problems that are more esthetic than functional. Enamel hypoplasia may be the result of hereditary, systemic, or local factors. Dental trauma is a local etiologic factor. It is relatively common in the primary dentition and can cause defects on the surface of permanent successors. Treatment for such defects can differ, depending on the depth of the spots. For deeper white-spot lesions, a composite resin restoration may be necessary. This is an excellent mode of treatment, due to both its low cost and its conservation of healthy tooth structure...

Multifocal epithelial hyperplasia (MEH), also known as focal epithelial hyperplasia and Heck disease, is a relatively rare condition caused by the human papillomavirus. This case report describes a 92-year-old man who presented with multiple, asymptomatic, circumscribed, soft, flattened papules in different sizes on the retrocommissure of his lower lip. The lesions were of 2 months' duration and had the same coloration as the adjacent normal mucosa. Histopathologic examination showed orthokeratinized stratified squamous epithelium with acanthosis, some areas of club-shaped rete ridges, and a few superficial epithelial cells with koilocytic changes and a mitosoid-like appearance...

The restoration of proximal surface cavities, originating from Class II carious lesions, to "normal" anatomical specifications is a fundamental objective for the dental practitioner. Cognitive interpretation of tooth morphology attained from evidence-based resources, together with the necessary psychomotor skills for correct design and completion, are considered essential strategies for restoration success. Also, the visualization of the original tooth structure, if present, should substantially benefit the dentist in the creation of a clinically satisfactory restoration...

The success of endodontic treatment is directly enhanced by elimination of microorganisms in infected root canals. Recently, chitosan, a natural, nontoxic biopolymer, has been introduced as an irrigant that has the capacity to remove the smear layer. The antimicrobial properties of chitosan as an endodontic irrigant have not yet been explored. The purpose of this study was to compare the antimicrobial efficacy of BioPure MTAD, 0.2% chitosan, 1% chitosan, 2% chlorhexidine gluconate, and 3% sodium hypochlorite (NaOCl) against Enterococcus faecalis, which is frequently isolated from persistent root canal infections...

This article describes a clinical case of gingival conditioning with provisional fixed prostheses to improve the esthetics of the soft tissues adjacent to fixed prostheses placed on malpositioned implants. Gradual application of pressure to the tissues is an easy, nontraumatic technique for inducing formation of papillae and reestablishing the appropriate shape and contour of the gingival tissues, thereby improving esthetics and phonetics. The proposed treatment proved to be effective in remodeling the surrounding soft tissues, providing suitable contours, and restoring esthetics and function lost due to surgical treatment with malpositioned implants...

Aerospace medicine is the medical discipline responsible for assessing and conserving the health, safety, and performance of individuals involved in air and space travel. With the upward trend in airline travel, flight-related oral conditions requiring treatment have become a source of concern for aircrew members. Awareness and treatment of any potential physiological problems for these aircrews have always been critical components of aviation safety. In a flight situation, oral and maxillofacial problems may in fact become life-threatening clinical conditions...

Epithelial-myoepithelial carcinoma (EMC) is a rare tumor, especially in the minor salivary glands. This case report describes a 40-year-old man who presented with an EMC on the palate. Histologically, the tumor was characterized by a biphasic structure consisting of duct-lining cuboidal cells in the inner layer and clear myoepithelial cells in the outer layer. The clear cells predominated, and the diagnosis was confirmed with immunohistochemical staining. The inner cuboidal epithelial cells were positive for cytokeratins, whereas the outer cells were positive for S-100 protein and smooth muscle actin...

Vascular anomalies such as hemangiomas or vascular malformations can produce negative esthetic effects in the maxillofacial region. These negative effects are the main complaints of patients. The clinical therapeutic efficacy of cryotherapy and sclerotherapy in the treatment of these lesions was evaluated in 10 patients who were clinically diagnosed with vascular lesions. Lesions were submitted to either cryotherapy or sclerotherapy, and follow-up showed that cryotherapy and sclerotherapy both were clinically effective in treating oral vascular lesions...
