Effectiveness of low power laser in reducing postoperative signs and symptoms after third molar surgery: a triple-blind clinical trial.

The objective of this research was to evaluate the effectiveness of using LPL (Low power laser) to reduce pain, edema, and trismus after impacted lower third molar extraction. A split-mouth randomized triple-blind clinical trial was conducted at the Federal University of Ceará. For inclusion criteria, it was necessary that the patient presented a clear indication for removal of both lower third molars, in addition to both molars being in similar positions.

Anti-Inflammatory Effectiveness of Oral Dexamethasone 4 mg on Mandibular Third Molar Surgeries: A Split-Mouth Randomized Clinical Trial.

Purpose: This study aimed to evaluate the anti-inflammatory effect of oral dexamethasone 4 mg in a single dose preemptively administered to reduce pain, swelling, and trismus following mandibular third molar surgeries.

Methods: A split-mouth randomized clinical trial was performed including 22 participants undergoing surgical removal of bilateral and symmetrically positioned third molars. A total of 44 teeth were allocated by simple randomization to either the test or nonintervention/control side.

Diagnostic challenge of T-cell MALT lymphoma in oral cavity.

Mucosa-associated lymphoid tissue lymphoma (MALT) is a neoplasm of B cells from the extranodal marginal zone and a non-Hodgkin lymphoma subtype. We report a case of MALT lymphoma in the hard palate in a 74-year-old woman with the previous diagnosis of lymphoid hyperplasia. The intetion about this letter is to show the appropriate clinical conduct and the diagnostic challenge about this pathlogy in oral cavity, stressing the importance to incisional biopsy and immunohistochemical analysis to guide the right diagnostic of this rare lesion.

Radiographic study of mandibular third molars: evaluation of the position and root anatomy in Brazilian population.

Objectives: The root anatomy and position of mandibular third molars are important factors in assessing the level of difficulty of surgical removal procedures. In this light, this study aims to identify the most frequent position and the root anatomy of mandibular third molars.

Methods: The study sample comprised 1205 mandibular third molars from 710 panoramic radiographs evaluated.

Ewing's Sarcoma Family Tumors in the Jaws: Case Report, Immunohistochemical Analysis and Literature Review.

Due to the low incidence of the Ewing's Sarcoma (ES) family tumors, the available epidemiology is likely to be unreliable, and at present, there are no standard diagnostic or clinical guidelines outlining their management. This report describes a case of peripheral primitive neuroectodermal tumor (ES/pPNET) which initially mimicked cystic lesions, and describes a comparison between ES and ES/pPNET in the jaws by the World Health Organization classification. This review addressed 63 cases published in the English literature between 1950 and 2016.

Oral compound nevus.

The melanocytic nevus is a benign and focal proliferation of nevus cells that can be congenital or acquired. Intraoral lesions are uncommon, and the etiology and pathogenesis are poorly understood. The occurrence rate of oral compound nevus is about 5.

Clinical and image findings in bisphosphonate-related osteonecrosis of the jaws.

Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is characterized as exposed bone in the jaws for more than 8 weeks in patients with current or previous history of therapy with bisphosphonates (BPs) and no history of radiotherapy in the head and neck. We report a case series of 7 patients with BRONJ and analyze the variations of clinical and imaging signs, correlating them with the presence or absence of bone exposure. Among the patients, 6 were women and 1 was a man, aged 42-79 years.

Central giant cell granuloma: treatment with calcitonin, triamcinolone acetonide, and a cystic finding 3 years and 6 months after the primary treatment.

Background: Central giant cell granuloma is a benign condition of the jaws which may present an aggressive behavior.

Case Report: A 9-year-old boy was complaining of swelling in the floor of the mouth. A solid swelling was observed in the area of the lower incisors.

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.

Impacted lower third molar fused with a supernumerary tooth--diagnosis and treatment planning using cone-beam computed tomography.

This paper reported a case of fusion between an impacted third molar and a supernumerary tooth, in which a surgical intervention was carried out, with the objective of removing the dental elements. The panoramic radiography was complemented by the Donovan's radiographic technique; but because of the proximity of the dental element to the mandibular ramus, it was not possible to have a final fusion diagnosis. Hence, the Cone-Beam Computed Tomography-which provides precise three-dimensional information-was used to determinate the fusion diagnosis and also to help in the surgical planning.
