Intrusive luxation of permanent upper central incisor into the nasal cavity: A case report.

This case report outlines a rare complete intrusion of a permanent, maxillary central incisor (tooth 11) into the nasal cavity, with a late diagnosis and treatment. An eight-year-old boy was referred to an oral and maxillofacial surgery service with absence of tooth 11 after an episode of a fall from his own height. Approximately 50 days after the trauma, the patient presented with a complaint of obstruction of the right nostril.

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.

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.

Conservative approach of condylar fracture in a child by the use of rubber elastics: 7-year follow-up.

Condylar fractures in pediatric patients occur frequently, often with minimal pain and discomfort. Thus, these fractures in children are overlooked during emergency care. Condylar fractures can be treated conservatively or by open reduction.

Radiographic evaluation of marginal bone level around internal-hex implants with switched platform: a clinical case report series.

Purpose: The purpose of this retrospective investigation was to evaluate the influence on the adjacent cervical bone of moving the implant-abutment microgap inward from the outer edge of an internal-hex implant platform (ie, a platform-switched configuration).

Materials And Methods: A convenience sample of 26 patients received 42 Frialit-2 (Dentsply-Friadent) implants for single tooth replacement and were divided into two groups. One group followed the original protocol (control group), and the other (study group) received narrower replaceable components.

Evaluation of mandibular ramus morphology using computed tomography in patients with mandibular prognathism and retrognathia: relevance to the sagittal split ramus osteotomy.

Purpose: The purpose of this study was to evaluate and compare the thickness of the mandibular ramus in patients with mandibular prognathism and retrognathia, as well as to assess the distribution of cancellous bone between the external and internal cortical plates above and posterior to the lingula.

Patients And Methods: The mandibular ramus of 40 patients, of whom 20 had prognathism and 20 had retrognathia, were evaluated by use of high-resolution computed tomography scanning.

Results: The mean thickness of the ramus in the prognathism group was 8.
