Recurrent dislocation of the temporomandibular joint: a literature review and two case reports treated with eminectomy.

Aims: Dislocation of the temporomandibular joint (TMJ) is a troublesome condition that occurs in a chronic or acute form. It is a distressing and highly embarrassing situation that may occur as a result of daily activities such as yawning, laughing, or during events that require keeping the mouth open for a long time. This review aims to present and discuss different conservative and surgical techniques to treat patients with a dislocated mandible, and to present two cases of surgical treatment.

Horizontal and vertical maxillary osteotomy stability, in cleft lip and palate patients, using allogeneic bone graft.

Objective: This study was carried out to evaluate maxillary stability after orthodontic-surgical treatment of patients with cleft lip and palate. Cephalometric analysis was applied to two different groups, with and without allogeneic bone graft.

Methods: The sample comprised 48 patients with cleft lip and palate.

Eagle's syndrome: treatment by intraoral bilateral resection of the ossified stylohyoid ligament. A review and report of two cases.

The complexities of Eagle's syndrome are examined according to anatomical, historical, clinical, and treatment aspects. There appears to be little correlation between the extent, form, and size of the anomalies of the styloid process and the stylohyoid ligament and the predictability of patients with related symptoms. Surgical treatment and the advantages and disadvantages of each surgical approach (intra- and extraoral) are discussed.

Oral and maxillofacial manifestations of familial adenomatous polyposis (Gardner's syndrome): a report of two cases.

Aim: The aim of this case report is to emphasize the importance of an early diagnosis of Gardner's syndrome through the detection of lesions appearing in the oral and maxillofacial area as well as to present two cases of the disease.

Background: Gardner's syndrome is an autosomal dominant disease characterized by gastrointestinal polyps that develop in the colon as well as in the stomach and upper intestine, along with multiple osteomas, skin, and soft tissue tumors. Cutaneous findings may include desmoid tumors, epidermoid cysts, and other benign tumors.

Oral focal mucinosis.

Oral focal mucinosis is an uncommon clinicopathologic condition that is considered the oral counterpart of cutaneous focal mucinosis. It is a disease of unknown etiology where the connective tissue undergoes a focal myxoid degeneration. A literature review disclosed 47 published cases of oral focal mucinosis.

Myopericytoma of the lip: report of case.

Background: Myopericytoma is a recently delineated entity showing a hemangiopericytoma-like vascular pattern. This rare mesenchymal neoplasm arises within the subcutaneous tissue of the extremities. Only 3 cases of myopericytoma involving the soft tissues of the mouth have been reported, and this case is the first, to the best of our knowledge, that involves the lips.

Osteochondroma of the mandibular condyle: literature review and report of a case.

Aim: The intent of this report is to present a brief review of the literature on osteochondroma and to present a case involving the surgical removal and replacement of a major portion of the condyle and angle of the mandible using free autogenous mandibular bone.

Background: While osteochondroma is the most common tumor of skeletal bones, it is relatively uncommon in the jaws occurring at the condyle or the tip of the coronoid process. This benign cartilage-capped growth is usually discovered incidentally on radiographic examination or on palpation of a protruding mass in the affected area.

Treatment of extrusive luxation by intentional replantation.

Background: The accepted treatment for extrusive luxation is repositioning of the extruded tooth at the earliest possible opportunity.

Case Report: Repositioning was not possible in a patient who presented for treatment 4 days after the accident, and therefore, an intentional replantation was performed instead. The tooth was carefully extracted, the blood clot removed from the alveolus and the tooth was then replanted.

Knowledge of general practitioners dentists about the emergency management of dental avulsion in Curitiba, Brazil.

The prognosis of traumatized teeth in general and of avulsed teeth in particular depends on prompt and appropriate treatment. Management of traumatic injuries may be a challenge to the non-specialized dentist, as they may occur when dentists are least prepared for it. The objective of this research was to investigate the knowledge of general practitioner dentists about the emergency management of dental avulsion in Curitiba, PR, Brazil.

Traumatic pseudolipoma of the oral cavity: report of a case.

An uncommon traumatic pseudolipoma of the oral cavity is presented. In this particular case there was evidence of previous trauma to the buccal fat pad during a difficult extraction of a maxillary premolar. Evidence is presented that iatrogenic trauma resulting in foreign body introduction might produce traumatic pseudolipoma in the oral cavity.

Dentoalveolar and mandibular body fractures caused by a horse kick: report of a case.

A rare case of multiple mandibular fractures and severe facial laceration is presented. The cause was a horse hoof kick to an unmounted equestrian. The pertinent literature is reviewed and the maxillofacial injuries associated with animal interaction are discussed.

Report of ankylosis of the temporomandibular joint: treatment with a temporalis muscle flap and augmentation genioplasty.

A case of true bilateral ankylosis of the temporomandibular joint (TMJ) is presented. A 19-year-old male patient had a life-threatening ear infection at the age of ten resulting in a progressive restriction of his mouth opening. He presented with almost complete lack of mobility of the mandible.

Combined endodontic therapy and surgery in the treatment of dens invaginatus Type 3: case report.

An accurate understanding of the morphology of the root canal system is a prerequisite for successful root canal treatment. Invaginated teeth have a complex root canal configuration that cannot be instrumented effectively and should be treated by both endodontic therapy and surgery. A case of dens invaginatus Type 3 in a maxillary lateral incisor with a periapical lesion and its successful treatment by these combined methods is reported.

Fracture of the alveolar process in a 2-year-old child: a report of an unconventional immobilization.

This is a report of fracture of the maxillary anterior segment of the alveolar process of an energetic 2-year-old child. The fracture was reduced under general anesthesia, and the fractured segment was immobilized using only 2-0 chromic gut in order to avoid a second surgical episode to remove traditional fixation after healing. The patient was followed for one year and healed well with no evidence of the lack of vitality of the involved teeth.

Aneurysmal bone cyst of the coronoid process of the mandible: a case report.

A rare case of aneurysmal bone cyst (ABC) located in the ramus of the mandible with involvement of the coronoid process is presented. The pressure of the slow growing tumor apparently caused severe resorption of the zigomatic arch. Treatment consisted of enucleation of the tumor via a pre-auricular access.

Recurrence of an ameloblastoma in an autogenous iliac bone graft.

A rare case of recurrence of an ameloblastoma in an iliac bone graft many years after the initial operation for a mandibular amelolastoma with evidence of soft tissue invasion is presented. A review of the literature disclosed only 11 cases of recurrence of ameloblastoma in bone grafts. In the case presented the initial operation was a hemimandibulectomy followed by autogenous iliac bone graft.

Multiple dentoalveolar traumatic lesions: report of a case and proposition of dental polytrauma as a new term.

Traumatic injuries to permanent teeth are common, and dramatic episodes can occur during childhood. The aim of this paper is to present a report of severe trauma to the orofacial complex of an 8-year old girl that resulted in multiple injuries. The use of the term "dental polytrauma" (concomitant different dental traumatic injuries) is advocated in this case presentation.

Aspergillosis of the maxillary sinus: review and case report.

A case of non-invasive aspergillosis affecting the maxillary sinus is presented. Reference is made to its possible aetiology (spores introduced to the antrum at the time of a root canal overfilling with a zinc oxide paste). A review is presented and the management of the case is described.

Partial spontaneous bone regeneration subsequent to mandibulectomy.

A case of spontaneous bone regeneration after mandibulectomy is presented. The patient was young and had a mandibular resection performed for a large fibroma. Only one of the condyles was preserved.

Congenital maxillary double lip: review of the literature and report of a case.

A double lip is an anomaly that may be either congenital or acquired. It occurs most often in the upper lip, although both upper and lower lips are occasionally involved. Surgical intervention (simple excision) produces good functional and cosmetic results.

Tooth replantation after traumatic avulsion: a 27-year follow up.

This report presents a case of replantation of a traumatically avulsed central incisor in a 32-year-old woman. The tooth was replanted after a 30-min extra-alveolar period. Emergency unconventional immobilization was performed, using 2-0 chromic gut, and a restorative composite made Gunning-type splint.
