Congenital epulis of the newborn: a case report.

The objective of this case report is to describe a congenital epulis of the newborn. A 10-day-old female neonate was brought to a dental clinic for examination of an intraoral lesion that was present at birth. No systemic changes were noted during the extraoral examination.

A rare case of regression of brown tumors of tertiary hyperparathyroidism after parathyroidectomy and renal transplant: A 5-year follow-up.

Tertiary hyperparathyroidism (HPT) is a rare condition that affects patients with secondary HPT, which develop hyperplasia of the parathyroid glands, thus causing an increase in parathyroid hormone levels. Bone alterations are the main consequences of this condition including the development of osteolytic lesions called brown tumor. This article reports an unusual case of brown tumors located in the maxilla and mandible in a 19-year-old man with chronic renal failure with hyperplasia of the parathyroid glands.

Orthognathic surgery in patients with cleidocranial dysplasia.

The aim of this study was to report the orthodontic-surgical approach of a 21-year-old female patient diagnosed with cleidocranial dysplasia. An orthognathic surgery was performed in the maxilla and mandible during the same procedure to correct an existing dentofacial deformity (class III malocclusion). In addition, malar prostheses were used to correct midface deficiency.

Computerized cephalometric study of the pharyngeal airway space in patients submitted to orthognathic surgery.

Introduction: Pharynx is a muscular organ with is sustained by craniofacial bones. It is divided into nasal, oral and hipopharynx, and can be considered as a tube that serves both respiratory and digestive systems. Its anatomical morphology permits that factors facilitate its obstruction, leading to the sleep apnea syndrome.

Intranasal inverted tooth: a rare cause of a persistent rhinosinusitis.

The aim of this study was to report a case of two supernumerary teeth in the nasal cavity in a 22-year-old woman who presented pain, rhinorrhea, and inflammation of the nasal mucosa (rhinosinusitis). The computed tomograph scan showed two radiopaque images that were diagnosed as supernumerary nasal teeth. One was unerupted in the floor and the other inverted, and erupted on the floor on the left side of the nasal cavity.

Comparison of buccal infiltration of 4% articaine with 1 : 100,000 and 1 : 200,000 epinephrine for extraction of maxillary third molars with pericoronitis: a pilot study.

We compared the buccal infiltration of 4% articaine with 1 : 100,000 or 1 : 200,000 epinephrine without a palatal injection for the extraction of impacted maxillary third molars with chronic pericoronitis. This prospective, double-blind, controlled clinical trial involved 30 patients between the ages of 15 and 46 years who desired extraction of a partially impacted upper third molar with pericoronitis. Group 1 (15 patients) received 4% articaine with 1 : 100,000 epinephrine and group 2 (15 patients) received 4% articaine with 1 : 200,000 epinephrine by buccal infiltration.

Xeroderma Pigmentosum - A case report with oral implications.

Xeroderma Pigmentosum is a rare autosomal recessive genetic disorder characterized by defective DNA repair leading to clinical and cellular hypersensitivity to ultraviolet radiation and carcinogenic agents. Important clinical features are: intense cutaneous photosensitivity, xerosis, poikiloderma, actinic keratosis, acute burning under minimal sun exposure, erythemas, hyperpigmented lentiginous macules, and malignant lesions in sun-exposed areas, including basocellular carcinoma, squamous cell carcinoma, and melanoma. There is a great involvement of many parts of the body, especially head and neck.

Peripheral osteoma of the maxillary sinus: a case report.

Background: Paranasal sinus osteomas are rare benign tumors. Although various theories such as trauma and infection have been proposed, it is difficult to establish the pathogenesis of osteoma. Osteomas may be detected with routine radiographic examination or the tumors may enlarge and cause symptoms.

Large calcifying epithelial odontogenic tumor with extension into the maxillary sinus: a case report.

Calcifying epithelial odontogenic tumor (CEOT) is a rare, locally invasive neoplasm characterized by the presence of amyloid material that can become calcified. It often is found in the posterior region of the mandible. Such tumors in the maxilla and those that invade the maxillary sinus are extremely rare.

Evaluation of the buccal vestibule-palatal diffusion of 4% articaine hydrochloride in impacted maxillary third molar extractions.

Aims: The aim of this study was to evaluate the vestibular-palatal diffusion of 4% Articaine with epinephrine 1:100,000 and 1:200,000, in impacted maxillary third molar extractions, without palatal injection.

Materials And Method: Two hundred teeth were selected from patients age 15 to 46. Patients were divided into 4 groups: 1A, were anesthetized with 4% articaine 1:100,000 and the surgery was initiated 5 minutes following anesthesia.
