Relapsing Polychondritis Concomitant With Synovial Chondromatosis of the Temporomandibular Joint.

Relapsing polychondritis (RP) is a rare, multisystem autoimmune disease characterized by inflammation, structural damage, and impaired function of cartilaginous tissues throughout the body. In the craniofacial region, this rare disease has been reported to affect structures of the ear and nose; however, reports of temporomandibular joint (TMJ) involvement are scarce. A second uncommon disorder of cartilage is synovial chondromatosis (SC), a progressive and proliferative disorder of the synovial membrane associated with the formation of variably sized cartilaginous and calcified loose bodies, often causing dysfunction of the joints and enlargement of the joint capsule.

Is the angulation of mandibular third molars associated with the thickness of lingual bone?

To find out whether the angulation of mandibular third molars is associated with the thickness of the bone at the site of impaction, and if so, which particular angulation affects the protective mechanism of the nerve, we retrospectively studied the thickness of lingual bone at the sites of impaction of 200 mandibular third molars in 149 patients using coronal, sagittal, and axial slices of cone-beam computed tomograms (CT). We measured the bone at the cementoenamel junction of the mandibular second molar, at the mid-root of the third molar, and at the apex of the root. Bone less than 1mm thick was defined as "thinning".

Three Synchronous Atypical Metastases of Clear Cell Renal Carcinoma to the Maxillary Gingiva, Scalp and the Distal Phalanx of the Fifth Digit: A Case Report.

Oral cavity metastasis of malignant tumors is extremely rare and accounts for only 1% of all malignant oral tumors. Renal cell carcinoma (RCC) can metastasize to any part of the body, with a 15% risk of metastasis to the head and neck region when the disease is disseminated and a 1% risk when it is not. RCC also is the third most common infraclavicular neoplasm that metastasizes to the oral cavity, after lung carcinoma in men and breast carcinoma in women.

Factors that are associated with injury to the inferior alveolar nerve in high-risk patients after removal of third molars.

Our aim was to answer the question: "Among patients at high risk of injury to the inferior alveolar nerve (IAN) after removal of 3rd molars, what factors are associated with postoperative neurosensory deficits?" We organized a retrospective, two-center study and enrolled a group of subjects who were at increased risk of injury to the IAN after removal of 3rd molars because radiographic findings indicated a risk on panoramic radiography that was high enough to warrant preoperative computed tomography (CT). The primary outcome variable was postoperative injury to the IAN. We used descriptive, bivariate, and multivariate analyses to assess the significance of differences, and probabilities of less than 0.

Incidentally detected asymptomatic metal foreign bodies (two nails) in shoemaker's maxillary sinus.

The diagnosis metal foreign bodies of maxillary sinus cannot be usually made in an acute setting and patients may present with chronic symptoms due to drainage and chronic irritation of the mucosa years later. Metal foreign bodies can be generally displaced to the maxillary sinus at the time of dental intervention. In this article, we report a very interesting case of 23-year-old male shoemaker with two metal foreign bodies (nails) which were non-related with any surgical intervention or trauma and found incidentally in the right maxillary sinus.

Keratocystic odontogenic tumors: predictive factors of recurrence by Ki-67 and AgNOR labelling.

Purpose: The purpose of the present study was to investigate the possible role of Ki-67 and argyrophilic nucleolar organizing regions (AgNOR) between the recurrent and nonrecurrent keratocystic odontogenic tumors (KCOTs). Another aim was to compare the correlation between these two markers.

Materials And Methods: 22 KCOTs were evaluated retrospectively.

The effect of irrigation temperature on bone healing.

Objective: Osteotomies, performed by rotational instruments, can cause temperature rise on the bone and elevated temperature can disrupt the bone healing. When the osteotomies are performed for the insertion of miniscrews, the bone healing disruption may cause stability loosening or failures. Saline irrigation is mostly used for the prevention of the heat generation during osteotomy.

Delayed removal of a maxillary third molar accidentally displaced into the infratemporal fossa.

The removal of an impacted maxillary third molar is an easy procedure for an oral and maxillofacial surgeon. The most commonly seen complications associated with this type of surgery are excessive hemorrhage, infection, pain, swelling, trismus, and root fractures. Although rarely encountered, unexpected complications may also arise during this procedure, such as the displacement of the tooth into an anatomic space.

Decompression, enucleation, and implant placement in the management of a large dentigerous cyst.

The dentigerous cyst is a developmental odontogenic cyst, accounting for 10% of all cysts of the jaws. The treatment options are decompression, marsupialization, or enucleation regarding the features of the lesions. In this article, a case of a 17-year-old adolescent girl having a large mandibular dentigerous cyst associated with an unerupted third molar is presented.

Clinical management of microstomia due to the static treatment of facial paralysis and oral rehabilitation with dental implants.

Facial-nerve paralysis is seldom seen and may occur because of a broad spectrum of causes. The most commonly seen cause of facial paralysis is the Bell palsy; iatrogenic causes and tumors are relatively rare. Facial asymmetry, drooling, garbled speech, and difficulty in feeding: all adversely affect the psychosocial conditions of the patients.
