Vestibuloplasty by modified Kazanjian technique in treatment with dental implants.

Dentists are often faced with extensively resorbed mandibular ridges with shallow buccal vestibule and high insertion of the mentalis muscle in relation to the crest of the ridge, causing the displacement of the prosthesis. Vestibuloplasty techniques aim at eliminating the muscle insertions, reposition the mucosa, and increase the area chapeável, giving more stability to the prosthesis. Among the techniques to deepen the vestibule are submucosal vestibuloplasties by secondary epithelialization and with mucosal and skin grafts.

Endaural access to remove the projectile from a firearm.

Background: Surgical approaches to temporomandibular region have been the subject of numerous controversies in the literature. Pre-auricular approaches have been used with the observance of high success rate, and during surgery history, various modifications of this approach were conducted in order to reduce irreversible sequelae. Thus, given the relevance of the study, this article proposes to alert the professionals that carry out these surgical approaches in relation to the anatomical structures involved and to describe and emphasise the benefits of endaural approach.

Subgingival microbiota from Cebus apella (capuchin monkey) with different periodontal conditions.

This present study evaluated the subgingival microbiota of the Cebus apella with different periodontal conditions kept by the Tufted Capuchin Monkey Procreation Center (São Paulo State University - UNESP) or free-ranging monkeys. For this purpose, clinical specimens of subgingival biofilm were collected from 52 monkeys, of both genders, 40 kept in captivity and 12 free-ranging monkeys. The primates were submitted to periodontal evaluation and biofilm samples were transferred to VMGA III transport medium and ultrapure water.

Multidisciplinary care in the intensive care unit for a patient with Prader-Willi syndrome: a dental approach.

Prader-Willi syndrome is a genetic neurobehavioral disease affecting children's development and resulting in obesity, reduced height, hypotonia, endocrine disorders and cognitive deficits, which may impair oral integrity. This study aims to report on a case involving a white male 15-year-old patient with Prader-Willi syndrome whose oral examination revealed bacterial plaque, gingivitis, poor occlusion, viscous salivation and multiple lip, jugal mucosa, inserted gum and tongue ulcerations. An excision biopsy revealed oral ulcerations typical of herpes, which were considered to be likely to correlate with herpes encephalitis.

Ligature of external carotid artery as an optional technique in a patient with von Willebrand disease.

The von Willebrand disease (vWD) is a hereditary coagulopathy. There is no gender predilection. Clinically characterized by mucocutaneous bleeding, especially nose bleeding, menorrhagia and bleeding after trauma.

Foreign body in preauricular region.

Foreign bodies, although they are often found throughout the body, to a lesser degree in the face, still constitute a diagnostic challenge for the trauma surgeon. Its removal means danger of damaging important facial anatomic structures, even if its exact position from the image data was known. So, the objective is to describe a clinical report of a patient (42 years of age, male sex) who experienced falling to the ground, attended by the Department of Surgery and Traumatology Bucco-Maxillo-Facial Surgery, Faculty of Dentistry of Araçatuba, São Paulo State University, and 2 days after the trauma, he reported difficulty in mouth opening and pain.

Sialolithiasis of the submandibular gland.

Sialolithiasis of the salivary gland is a benign pathology that occurs most frequently in the submandibular gland because of its anatomic features. Depending on the sialolith size and calcification degree, it can be visible in radiographic examinations. Commonly, patients may experience pain and/or edema, when the ducts are obstructed.

Dental implants in patients with osteoporosis: a clinical reality?

Osteoporosis is a systemic disorder characterized by generalized decrease in bone mineral density. Dental implantology is a specialty with high predictability when both quantity and quality of the bone are respected. Therefore, the diagnosis and the implant treatment in patients with osteoporosis are important.
