Remodeling dental anatomy vs sham therapy for chronic temporomandibular disorders. A placebo-controlled randomized clinical trial.

Background: Evidence regarding the etiology or effective treatments for chronic orofacial pain, the majority diagnosed as temporomandibular disorder (TMD), is limited.

Purpose: To investigate whether occlusal equilibration therapy (ET) and decreasing the (higher) angle of the lateral guidance on the nonworking-side leads to a reduction in chronic TMDs intensity.

Methods: It was conducted a randomized, explanatory, single blind with blinded assessment, placebo-controlled trial with strong protection against bias involving patients with chronic TMDs.

Vascular Lesions: GLUT-1 expression as a diagnostic tool to discriminate tumors from malformations.

Vascular lesions constitute a widely heterogeneous group of tumors and malformations. For head and neck vascular anomalies, most studies have not attempted to make the differential diagnosis between true hemangiomas and vascular malformations, because an accurate diagnosis remains a challenge for physicians. The successful treatment of vascular anomalies depends on a profound knowledge of their biologic behavior and correct classification.

A comparative study of platelet-rich plasma, hydroxyapatite, demineralized bone matrix and autologous bone to promote bone regeneration after mandibular impacted third molar extraction.

Objectives: 1) to compare mandibular bone regeneration by applying autologous bone, platelet-rich plasma and two biomaterials (synthetic calcium hydroxyapatite, and demineralized bone matrix), and thus establish the potential benefits of these biomaterials in the regeneration of postextraction alveolar bone, 2) to identify which of them accelerates more bone regeneration and 3) to determine whether there are differences in the postoperative period (pain, swelling, trismus, infection) depending on the material used.

Study Design: It consists in a prospective, controlled (with a split- mouth design) and double blinded study. We use as a model an easily reproducible non-critical bone defect: the defect that remains after extraction of mandibular impacted third molar.

Temporomandibular juxtaarticular chondroma: case report.

Chondromas are benign tumours composed of mature hyaline cartilage. We present here the first case in the English language medical literature of juxtaarticular chondroma of the temporomandibular joint in the parotid region. Within the rarity of cartilage disorders of the temporo-mandibular joint (TMJ), this particular condition is a diagnostic curiosity.

Oral leiomyoma in retromolar trigone. A case report.

Leiomyomas are bening tumours originated on smooth muscle. The most frequent site of appearance are uterine myometrium, gastrointestinal tract and skin. The highest incidence occurs between 40 and 49 years of age.

Metastatic renal cell carcinoma presenting as a parotid tumor.

Metastases of malignancies to the parotid region are relatively infrequent (21%-42% of all malignant tumors 1 ), but metastases of infraclavicular origin are infrequent (0.16%-4% 1,2 ). From 1986 to 1998, only 17 cases of parotid metastases of renal clear cell carcinoma were documented in the literature reviewed.
